interpretation
Explanatory item refers to the explanatory content
Tongxing Environmental Protection Technology Co.Ltd(003027) , the company and the company refer to Tongxing Environmental Protection Technology Co.Ltd(003027)
Beijing Fangxin refers to Beijing Fangxin Lihua Technology Co., Ltd., a holding subsidiary of the company
Anhui Fangxin refers to Anhui Fangxin Lihua Environmental Protection Technology Co., Ltd., a wholly-owned subsidiary of Beijing Fangxin
Ma'anshan Fangxin refers to Ma'anshan Fangxin Environmental Protection Technology Co., Ltd., a wholly-owned subsidiary of Beijing Fangxin
Thermal power refers to thermal power generation, mainly coal-fired power generation (coal power)
Non electric industry refers to the coal-fired industry other than thermal power, mainly including steel, coking, building materials and other industries
The flue gas treatment refers to the removal of sulfur oxides, nitrogen oxides, dust and other harmful substances in the exhaust gases of coal-fired boilers and kilns, so as to make the flue gas discharged up to the standard after combustion. Generally, it can be subdivided into dust removal, desulfurization and denitration
According to the specific needs of users, complete the overall scheme design, material procurement, construction and commissioning of the flue gas treatment project, and finally deliver it to users for operation after passing the acceptance, so as to achieve the purpose of emission reduction and pollution control
EPC refers to the general contracting of the project. The company is entrusted by the owner to contract the whole process or several stages of the design, procurement, construction and commissioning of the engineering construction project in accordance with the contract
Sulfur oxides include a variety of sulfur compounds, such as sulfur dioxide, sulfur trioxide, sulfur trioxide, sulfur sevoxide, etc. Sulfur dioxide and sulfur trioxide are common in the atmosphere, and their mixture is represented by SOX. Sox is the main pollutant of air pollution and environmental acidification. It coexists with water droplets and dust in the atmosphere. Due to the catalytic oxidation of iron and manganese in particles (including liquid and solid), sulfuric acid mist is formed or acidic rainfall is caused
Nitrogen oxides include a variety of compounds, such as nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen trioxide, nitrous oxide, nitrogen tetroxide and nitrogen pentoxide. The environment is exposed to several gas mixtures, often referred to as nitrous smoke (gas), which are mainly nitric oxide and nitrogen dioxide, mainly nitrogen dioxide, and the mixture is represented by NOx. Nitrogen oxides have different degrees of toxicity
Dust removal refers to the technical measures to remove particles from dusty gas to reduce its emission to the atmosphere
Desulfurization refers to the process of removing sulfur from fuel before combustion and flue gas before emission
Denitration refers to the process of removing nitrogen oxides from flue gas
Selective non catalytic reduction: SNCR refers to the injection of raw agents (such as ammonia and urea) into the boiler for selective reaction with nitrogen oxides. Without catalyst, it reacts with NOx in flue gas to generate nitrogen and water
Selective catalytic reduction: refers to the use of reducing agents (such as ammonia and urea) to "selectively" react with nitrogen oxides in flue gas under the action of catalyst to generate non-toxic and pollution-free nitrogen and water.
At present, it has become the most widely used and most
An effective flue gas denitration technology
Denitration catalyst refers to the core of SCR denitration technology. In SCR reaction, it promotes the reductant to selectively react with nitrogen oxides in flue gas at a certain temperature
Low temperature SCR denitration catalyst refers to the catalyst with high denitration performance in the temperature range of 180 ℃ ~ 300 ℃
Emission limit refers to the highest emission value in the national emission standards for various pollutants
Generally, it is a more stringent emission standard than the special emission limit. The ultra-low emission standard of the thermal power industry is that under the condition of 6% reference oxygen content, the emission concentration of soot, sulfur dioxide and nitrogen oxide shall not be higher than 10mg / m3, 35mg / m3 and 50mg / m3 respectively; According to the ultra-low emission instruction scheme for ultra-low emission transformation of iron and steel enterprises (Exposure Draft), the ultra-low emission standard of the iron and steel industry is that the hourly average emission concentrations of particulate matter, sulfur dioxide and nitrogen oxides are not higher than when the reference oxygen content is 16%
10mg/m3、35mg/m3、50mg/m3； The hourly average emission concentrations of particulate matter, sulfur dioxide and nitrogen oxides from other pollution sources shall not be higher than 10mg / m3, 50mg / m3 and 150mg / m3 respectively
Spray DryAbsorber, spray drying process is a semi dry flue gas desulfurization technology, and its market share of SDA is only inferior to that of wet process. The method is to spray the calcium hydroxide of the absorbent slurry in the reactor, spray the sulfur dioxide in the flue gas, and evaporate at the same time by the hot flue gas, and generate solid and collect by the dust collector.
Circulating fluid bed, flue gas circulating fluidized bed desulfurization process, is a kind of CFB technology of semi dry desulfurization. Through multiple recycling of absorbent, the contact time between absorbent and flue gas is more than half an hour, which greatly improves the utilization rate of absorbent
Gas heater, flue gas reheater, uses raw flue gas to add the desulfurized net flue gas
GGH refers to heat, which makes the exhaust gas temperature above the dew point, reduces the corrosion to the inlet flue and chimney, and improves the diffusion of pollutants; At the same time, reduce the temperature of flue gas entering the absorption tower and reduce the technical requirements for anti-corrosion in the tower
The reporting period refers to the period from January 1, 2021 to December 31, 2021
Yuan, ten thousand yuan and one hundred million yuan refer to RMB yuan, ten thousand yuan and one hundred million yuan
