To further standardize the construction and operation management of air pollution control projects in Xuzhou thermal power industry, protect and improve the environment, and prevent and control environmental pollution, our city has recently issued the "basic specification for air pollution control in Xuzhou thermal power industry in 2019". The specification puts forward specific requirements for the storage, loading and unloading, transportation of raw fuels, storage and transportation of by-products, flue gas collection and centralized purification and treatment system, vehicle transportation, road dust control system, monitoring and monitoring system, etc

monitor air pollution indicators in real time and publish them to the society in real time

it is understood that this specification is a general requirement for the prevention and control of air pollution in the thermal power industry throughout the city

the specification requires that the enterprise should operate legally, have the corresponding production qualification, industrial and commercial registration, land use, environmental protection procedures and other basic elements, and comply with industrial policies. Enterprises shall operate, maintain and manage air pollution prevention and control facilities in accordance with the requirements of relevant laws, regulations, standards and technical specifications, and be responsible for air pollution caused by their own production and operation activities, and bear the damage caused according to law

coal fired power generation and cogeneration enterprises support coal-fired boilers to implement the ultra-low emission standards promised by the emission permit in case of range jump. All production links that produce dust, such as raw fuel processing, transportation, loading and unloading, storage, etc., should be operated in a sealed environment; The storage link should be equipped with spraying or fog gun facilities to suppress the dust generated during loading, unloading and transportation; Dust suppression measures such as spraying or adding dust collection and dust removal shall be taken to prevent the emission of air pollutants

enterprises must, in accordance with the requirements of relevant specifications, configure air monitoring equipment at the main emission outlets and plant boundaries such as desulfurization, denitration and dust removal facilities, and connect with the monitoring platform of the environmental protection department to monitor air pollutant indicators in real time and publish them to the society in real time

raw fuel storage, loading and unloading, transportation and preparation system

closed special storage must be built

delimit special logistics channels

raw fuel yards such as enterprise coal must realize ground hardening. For those that cannot be hardened due to process requirements, they must be transformed and qualified in accordance with relevant specifications. Greening and covering measures shall be taken for the exposed ground in other areas of the plant to prevent dust

the storage places of raw fuels such as coal in the enterprise must be built with closed warehouses, silos, strip or circular closed silos for storage in recent years, which must meet the safety protection requirements and comply with relevant regulations. For example, powdery materials such as pulverized coal, lime or limestone powder must be stored in fully enclosed silos such as silos. Bag type dust collectors or other dust collection and treatment facilities should be set on the discharge hoppers and storage silos of auxiliary materials such as limestone. A special logistics channel must be delimited and clearly marked between the materials in the closed special storage and the loading port. The passage should be kept clean and there should be no dust on the road. If there is dust pollution during the transportation of coal and other raw fuels in the closed special storage, fixed and mobile sprinkler devices must be equipped

the conveyor belt, bucket wheel machine and other conveying equipment supporting raw fuels such as coal should be placed in the closed material warehouse, and the transmission equipment outside the closed material warehouse should be sealed. Dust collection devices should be installed at each transfer point and unloading point, and spraying or dust collection and dust removal measures should be taken if they cannot be sealed

by product storage and transfer system

special tank cars should be used for transportation

temporary storage places should be closed

temporary storage in the ash plant should adopt closed ash silos and slag silos, and dust removal facilities should be configured at the top pressure relief port, batching and blanking port and other positions; Pneumatic conveying is adopted in the fly ash plant, and special tank cars shall be used for transportation. Temporary storage places for gypsum, desulfurization and other by-products shall be closed

the management and control of the wet ash yard should be strengthened to ensure the centralized display of the upstream and downstream industrial chain of new materials and the water seal and coverage of the ash holding surface of end products, so as to prevent unauthorized mining

flue gas collection and centralized purification and treatment system

all coal-fired units must be installed with desulfurization facilities

exhaust funnel permanent sampling

boilers that produce air pollutants must build flue gas collection systems and centralized purification and treatment facilities in accordance with the relevant national and Jiangsu provincial standards. Except for coal-fired boilers that have implemented "coal to gas", "dry desulfurization" and are listed in the shutdown plan, the rest need to be installed with cooling and dehumidification systems, And ensure normal operation

all coal-fired units should be equipped with desulfurization facilities, and coal-fired units other than circulating fluidized bed boilers need to be equipped with denitration facilities. Therefore, we need to open the fan cover and biomass fueled units to be equipped with efficient dust removal facilities. The processing capacity of desulfurization, denitration and dust removal devices must meet the production needs, must be able to maintain long-term stable operation, and must be qualified products designed and produced by professional manufacturers. The exhaust funnel must be provided with permanent sampling ports and constructed in accordance with the relevant national and Jiangsu specifications

the Trinity cleaning mode of vehicle transportation and road dust control system

ensures that the road surface is free of dust

special passages for logistics vehicles to enter and leave the plant must be set up, and the transportation vehicles entering the site must be covered tightly. The outlet of the special passage for materials in the production area must be equipped with a car wash station, where a two-stage (or three-stage) sedimentation tank should be set. The car wash sewage is recycled after sedimentation. The settled sludge shall be cleaned regularly and disposed reasonably

the transportation vehicles leaving the site must be covered tightly, and the chassis, wheels and body of the vehicle must be washed clean, and no dust is allowed on the road. In winter and other periods that are not suitable for washing, the pavement cleaning should be strengthened to prevent dust accumulation. The roads in the plant area should be hardened, equipped with cleaning facilities, sprinkler or dual-purpose sprinkler, and the main logistics channels must achieve the dust suppression effect of "wet but not dry"

enterprises should establish a full-time cleaning team and adopt the Trinity cleaning mode of "machine washing and manual cleaning" to ensure that there is no dust on the road. In the case of low temperature in winter without watering conditions, the frequency of suction and sweeping and manual cleaning should be increased

monitoring, monitoring system

full coverage, no blind area

electronic bulletin board real-time update data

the production area of the enterprise must be installed with a video monitoring system to achieve full coverage and no blind area of the monitoring system. The monitoring scope includes all kinds of material storage yards, production workshops, loading and unloading ports, sprinklers, as well as major air pollution control facilities, pollution source monitoring station buildings, car washing stations, factory roads and logistics vehicle entrances and exits. The storage time shall not be less than 3 months, and the storage time at the entrance and exit of logistics vehicles during the control period in autumn and winter shall not be less than 6 months

enterprises should set up electronic bulletin boards, which should be placed in eye-catching positions such as the main gate of the plant, to announce the real-time emission concentration of air pollutants and emission standards, date, wind direction and heavy pollution weather warning information, control measures, etc. to the society, and update the data in real time

enterprises must set up exhaust outlet monitoring points on the flue gas emission as required, and install, operate and maintain the automatic monitoring system of pollution sources to monitor the concentration of atmospheric pollutants such as soot, sulfur dioxide, nitrogen oxides, mercury and its compounds in real time and continuously

early warning and emergency response

during the orange and above heavy pollution weather early warning period

prohibit heavy trucks from entering and leaving the factory

enterprises should establish an emergency response leading group, formulate an emergency control plan for heavy pollution weather, and strengthen drills. After the emergency control plan is submitted to the local environmental protection department for review and filing, a letter of commitment is signed and publicized to the public

after receiving the heavy pollution weather warning notice, the enterprise should immediately start the emergency response according to the response level, and take measures such as limiting production, stopping production or stopping production by batch to reduce the atmospheric pollution emission load in strict accordance with the requirements of the heavy pollution weather emergency plan and emission reduction list. During the orange and above heavy pollution weather warning period and key periods, the entry and exit of all diesel trucks shall be registered. In principle, heavy trucks are not allowed to enter and leave the plant
