Recently, Hangzhou Provincial People's Government for the quality of atmospheric environment issues issued a deadline for compliance plan, as follows.
First, the situation and challenges
Since the "Atmospheric ten" implementation of Hangzhou to build an ecological civilization as a guide to improve the quality of atmospheric environment as the goal, carry out air pollution prevention and control actions to protect the G20 summit in Hangzhou as an opportunity to promote a strong "coal-fired flue gas, industrial emissions , vehicle exhaust, dust gray gas, urban and rural exhaust "other" gas cohabitation ", strengthen regional joint prevention and control, air pollution control and achieved remarkable results, no built coal-fired thermal power, iron and steel producers no, no emission vehicles "three noes" urban atmospheric environmental quality continues to improve.
(A) Key Performance
1, ambient air quality improved significantly.
In the case of the national economy with an average annual growth of 9.1% of the "second five" major pollutants emission reduction achieved remarkable, sulfur dioxide, total nitrogen oxide emissions compared to 2010, respectively, decreased by 21.9%, 26.5%, exceeding the state-assigned the reduction targets and tasks.
2, energy and industrial structure gradually optimized.
The city's total energy consumption growth narrowed year by year, total energy consumption in 2015 was 39.48 million tons of standard coal, an average annual increase of "Twelfth Five-Year" period is only 3.4%, compared with the "Eleventh Five-Year" down 2.1 percentage points.
3, industrial pollution prevention deepened.
Promoting desulfurization and denitrification and dust removal facilities, coal-fired thermal power generating units are completed desulfurization, denitrification facilities, a total of 87 coal-fired thermal power generating units ultra-low emissions transformation.
4. The motor vehicle exhaust pollution prevention and continuous progress.
"Twelve Five" period, and comprehensively promote the yellow car out of work in 2015, the city basically eliminated emission vehicles.
5, comprehensively promote urban and rural waste gas treatment.
"Twelve Five" period, to strengthen the construction site dust management, the establishment of civilized city construction sites and construction dust pollution comprehensive rectification work leading group, the establishment of municipal, district, enterprise level management network.
6, continue to strengthen capacity building.
"Twelve Five" period, the construction of Hangzhou, air pollution control system for continuous improvement, introduced the "Hangzhou pollution prevention provisions of the atmosphere", and the issuance of the annual air pollution control plan and supporting the implementation of assessment methods.
(B) there is a problem
1, ambient air quality improvement into the bottleneck.
In recent years, the effectiveness of atmospheric environmental quality improved significantly, but control "Ambient Air Quality Standard" (GB3095-2012) secondary standards are still gaps.
2. Regional collaborative governance is still run-in period.
The analysis results Hangzhou PM2.5 sources, the contribution to the local discharge air in an urban environment PM2.5 concentration 62% -82%, about 72% on average. Regional transport to urban ambient air concentrations of PM2.5 contribution accounts for 18% -38%, an average of about 28%, in different seasons affect the Hangzhou area varies. A higher proportion of regional transport and complexity of the transmission source region to control air pollution in Hangzhou more difficult to establish and improve regional air pollution is critical institutional mechanisms of joint prevention and control.
3, into the deep water of air pollution control.
In recent years, Hangzhou, air pollution prevention and control work has achieved remarkable success, but there are still many "shortcomings" in the current governance of air pollution, structural, further highlights the deep-seated problems.
(1) optimize the industrial structure needs to continue, heavy pollution in some areas, high energy-consuming industries and the "messy dirty" business issues are still quite prominent.
Total coal (2) Energy consumption is still high, the use of natural gas supply capacity and scale need to be strengthened, industrial parks (industrial parks) are still blind spots of central heating, renewable energy development and utilization efforts still need to increase.
(3) heavy end of the treatment, the light source control and cleaner production, the work of "second five" major emission control measures revolve around the end of pollutants on source control and cleaner production process is still insufficient attention.
(4) With SO2, NOx reduction work continued in-depth, project emissions space shrinking, VOCs emissions is more a lack of technical means, the rigidity of the vehicle population growth, vehicles, ships and non-road mobile machinery and other mobile source pollution control to be a breakthrough. With the difficulty of the work of prevention and control of atmospheric pollution key areas continue to increase, the city is still on air pollution control into the deep water.
4, the basic work is still weak period.
Municipal government attaches great importance to air pollution control work, work-related basis more solid, but there are still many weak links. Hangzhou, organization and leadership of atmospheric pollution control systems should be strengthened, the department division of labor, the working mechanism of collaborative governance needs improvement. Local standards should be further improved, pollution resources and a list of atmospheric pollution still need to be updated regularly.
Gas, the working principle of a steam steam normal pressure boiler price gas heating device (burner) to release heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a lot of steam into the drum for generating steam separator (DC out furnace), separated the steam entering the superheater full, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. Power generation boilers are generally provided with a reheater, steam is used to heat the work of the high-pressure cylinder, the reheater go out of the reheat steam, the low pressure cylinder continuously to generate power. Plain speaking, a steam boiler the burning of the fuel absorbs heat energy must be water parameter (such as pressure, temperature, etc.) of the steam device. Boilers and boiler furnace divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace and burning the fuel to steam, with the basic principles of almost boiling water, the pot equivalent kettle, oven stove equivalent. Horizontal gas steam boiler Schematic heating apparatus (burner releases heat, radiation is first absorbed by the water wall heat transfer, vaporization of water boiling water wall, a lot of steam into the drum for generating steam separator (DC out furnace), separated full steam enters the superheater, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. power generating boilers are generally provided with a reheater, is used to heat the steam by the high pressure acting cylinder, and reheated steam reheater go out, the low-pressure cylinder continuously to generate power. plain speaking, a steam boiler the burning of the fuel absorbs heat energy must be water parameters ( the apparatus steam pressure, temperature, etc.) of the boiler and the boiler furnace is divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace burning fuel converted steam, boil water with the basic principle is similar to the equivalent of pot kettle, oven stove equivalent. vertical gas steam boiler principle diagram vertical gas steam boiler Furnace is an energy conversion device, the input energy to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, the boiler through the conversion of thermal energy must be externally output with steam, hot water or organic heat . used for power plant, boats, locomotives and mining enterprises. the main rationale original working passed to a boiler water in the container after use of the thermal energy released or the fuel burned in the industrial production of heat, the temperature of the water reaches the demanded or must steam pressure thermal equipment boiler in the "pot" and "furnace" two somewhat performed in conjunction with the water into the boiler in the future, the heat in the soda system boiler heating surface will absorb transferred to the water, the water heated to a bound of temperature and pressure generating hot water or steam, is drawn applied. in some incineration equipment, continued burning of the fuel heat release, high temperature flue gas occurs by thermal incineration of communication, transferring heat to the boiler heating surface, the temperature was gradually lowered itself, and finally discharged from the chimney classification steam boiler: a, divided by the fuel: 1, gas boiler, 2, oil-fired boiler, 3, gas boiler, 4, electric heating boilers, 5, atomic energy boiler, 6, waste heat boiler, etc., during the first four at most, the most common, the lowest operating costs of gas-fired boilers, but large area, environment pollution, the operator requested more; fuel gas boiler high degree of automation, operation cost is higher than gas, smaller footprint, fewer requests operator; electric heating boiler I have not had the operation, but the operation cost should be the highest, but a small boiler area, environmental best; other boiler is not introduced because they do not understand Second, by mode of heat transfer into the fuel gas-fired boiler is usually fire tube boiler water tube boiler, fire tube boilers, water, fire tube boilers and other. typical model: WNS series (horizontal burning boiler combustion chamber), the characteristics of such boilers: simple structure, an additional amount of evaporation is generally small (typically ten tons or less, there are also large, but usually do not exceed 35 tons), Kai boosting faster furnace, boiler water is relatively low request; gas boiler are usually water-tube boiler, water tube boiler high thermal efficiency, but messy configuration, the boiler high quality requested. Third, by additional pressure into the low-pressure boilers, pressure boiler, high pressure boiler Fourth, the use is divided into days boilers, industrial boilers, power generation, marine boilers.
Basics gas and steam oven basic principle as the principle gas steam steam normal pressure boiler price and knowledge: steam as a heat carrier gas, forced circulation pump circulating the liquid phase, and then reheated to return, once-special industrial furnace. Widely used, such as petrochemicals, textiles, printing, plastics, rubber, food processing, wood processing, thermal asphalt, carton production, vegetable dehydration, drying, and other drying foundry sand. Gas steam boiler is an energy, security, heating equipment, is an ideal alternative to steam boiler products. The working principle is conveyed back to the respective thermal heating apparatus petroleum oil heater (endothermic) (organic heat), heat conduction through the (thermal energy release), and then returned to the furnace, formation of a closed circle in the process of compulsory to achieve the purpose of heating. Performance and features: 1, low temperature. As the temperature rises conductive oil, the viscosity of the system will continue to reduce resistance to decline, it will also reduce stress, more conducive to the safe operation and safe operation. Steam boiler is high pressure high temperature plume. 2, gas and steam heating system uses hot water inlet and outlet temperatures and equipment is 20-30 degrees, the closed forced circulation, heat recovery can be repeated, there is no waste, high thermal efficiency, energy-saving effect. 3, a low pressure gas and steam heating system, requires pressure equipment and the system will be reduced, and therefore, a simple production process of steam boilers, low investment costs. 4, the thermal efficiency can be maintained at optimal levels in various loads a level of 320 degrees and can adapt to the production requirements of the following types of thermal load, and temperature control can be precisely adjusted. 5, heating furnace to increase two to three times the temperature cycle can provide a wide range of processes, a variety of equipment to meet the different temperatures greatly reduces the need for investment in equipment.
