Knowledge of flue gas treatment for waste incineration power generation
Garbage incineration power generation refers to the work of using high-tech garbage incineration equipment to generate electricity in garbage incineration plants. However, the process of garbage incineration generates air pollution, which causes great harm to human health. Therefore, it is necessary to treat the air generated by garbage incineration technology. At present, the waste incineration power generation flue gas treatment technology is reliable, advanced, mature, and can provide the optimal flue gas treatment plan based on the treatment effect, achieving the goal of harmless to human health.1. What are the other emission indicators of waste incineration power plants? Compared to international standards, at what level?The biggest difference between domestic waste and foreign waste is that our waste is relatively wet. At present, the equipment is mature in technology, and the furnace temperature and flue gas emissions can be monitored in real time. That is to say, the data of various harmful emissions in the flue gas of incineration power plants can be seen by the Environmental Protection Bureau at all times, playing a supervisory role.All emission indicators in the flue gas can meet the requirements of the Notice on Further Strengthening the Management of Environmental Impact Assessment for Biomass Power Generation Projects issued by the National Environmental Protection Commission [2008] No. 82. The main project indicators can meet the requirements of this standard and also meet the standards of the European Union, which is very low and will not have an impact on the environment.The emission indicators of flue gas from incineration of garbage have reached the international level.2. What are the main components of smoke generated after garbage incineration?The main components of the flue gas after garbage incineration include dust, sulfur dioxide, carbon dioxide, nitrogen oxides, etc., as well as hydrogen fluoride, hydrogen chloride, furan, dioxins, etc. These harmful components will be treated and removed through advanced technological means, and the final emissions through the chimney are in accordance with the national environmental protection standard [2008] No. 82, with little impact on the environment.3. Will the smoke emitted from the chimney be toxic?After high-temperature combustion at temperatures ranging from 850 ℃ to 1100 ℃, some harmful gases can be decomposed, and then processed by a "semi dry method+activated carbon adsorption+bag dust removal" purification system. The harmful gases have been fully removed and can reach high standards. The dust (fly ash) adsorbed by harmful gases is treated as dangerous goods and strictly controlled. Finally, the gases discharged through the chimney are all up to standard, and the chimney height is generally 80 meters, Can be diffused in the atmosphere. Sometimes due to weather changes, white gas may be seen coming out of chimneys, which is just evaporated water vapor.4. Will the chimney emit ash outside?After high-performance special cloth bags are used to collect dust in the flue gas, there will be no floating ash phenomenon. Because the dust collection rate of bag dust removal can reach 99.99%, the dust is basically completely removed, so there will be no dust in the smoke discharged from the chimney. In addition, because it is not visible to the naked eye, there will be no floating ash phenomenon.5. How to control the production of NOx (nitrogen oxides)?The mechanism of NOx generation includes two aspects: firstly, the nitrogen content in garbage generates NOx during combustion, and secondly, the nitrogen content in the air oxidizes to produce NO2 at high temperatures. The most reasonable way to suppress NOx generation is to control the amount of NOx produced during combustion by limiting the amount of primary combustion air. Practice has proven that this is an effective method. Based on this principle, this project ensures that the NOx content (equivalent to NO2) in the flue gas is less than 400mg/Nm3 through furnace design and combustion control. Industry actual data shows that NOx control can be achieved through combustion control. The design reserves the location of SNCR (Denitration, i.e. removal of nitrogen oxides) device and spray inlet, which can greatly reduce NOx emissions and have no impact on the environment.

What questions should be paid attention to in different situations of exhaust gas treatment
What issues should be paid attention to in the treatment of exhaust gases in different situations?1. Treatment of inert gases:Although inert gases are not dangerous, the accumulation of a large amount of inert gases can reduce the surrounding oxygen content, leading to suffocation.(1) Discharge in an appropriate outdoor location.(2) If the steel cylinder or instrument is indoors, an exhaust duct can be connected to slowly discharge it outdoors.2. Treatment of combustion gas:(1) Powder, petroleum, grease, and flammable substances adhered to container valves or utensils must be thoroughly removed before proceeding with the treatment of auxiliary gas.(2) It is strictly prohibited to handle combustion gases and combustible gases in the same area or nearby to prevent explosion accidents.(3) There should be no sources of ignition, combustibles, or explosives around the area where combustion supporting gases are being processed.3. Handling of combustible gases:(1) If the emission of combustible gases is large, it is advisable to choose a place with fewer people as much as possible, pay attention to prohibiting fires in the surrounding area, and prepare corresponding fire extinguishers, sand, and water.(2) When discharging combustible gases from steel cylinders, workers should stand on the side of the gas outlet to prevent gas spraying and injuring people.(3) When using the combustion method for treatment, a pressure reducing valve should be installed to control the speed of combustible gas and try to slowly release the gas, so that it can be fully burned in the combustion device.4. Treatment of toxic gases:(1) When handling toxic gases, workers must wear protective equipment such as gas masks and gloves. Personnel unrelated to the handling work are prohibited from entering the toxic gas processing area.(2) The absorbents and adsorbents used in the treatment of toxic gases should ensure their effectiveness before use.

Comparison of photocatalytic oxidation and biological deodorization methods for treating waste gas
Comparison between photocatalytic oxidation and biological deodorization methods for treating waste gas:Biological deodorization method, also known as biological decomposition method, is the process of using circulating water flow to contain pollutants in foul smelling gases in water, and then cultivating microorganisms in a water culture bed to degrade the pollutants into low harmful substances. The deodorization efficiency can reach 70%, but due to the influence of microbial activity, the cultivated microorganisms can only treat one or several gases with similar properties. In order to improve treatment efficiency and stable operation, Frequent addition of chemicals, control of pH value, temperature, etc. is necessary, which results in relatively high operating costs and requires more manual labor. In addition, once the organism dies, it will require a longer period of re cultivation.The photocatalytic oxidation method uses high-energy UV rays to decompose and oxidize the molecular chains of odorous substances in the photodegradation purification equipment, change the material structure, and decompose and oxidize polymer pollutants into low-molecularly harmless substances. Its deodorization efficiency can reach 99%, and the deodorization effect greatly exceeds the national emission standard for odorous substances issued in 1993 (GB14554-93). It can process ammonia, hydrogen sulfide, methyl mercaptan, methyl sulfide, benzene, styrene, carbon disulfide, etc High concentration mixed gases such as trimethylamine and dimethyl disulfide have an internal light source that can be used for three years, and the equipment has a lifespan of more than ten years. The purification technology is reliable and very stable, and the purification equipment does not require daily maintenance. It can be used normally by simply connecting the power supply, with low operating costs and no secondary pollution.

Working principle of activated carbon adsorption tower
The activated carbon adsorption tower device mainly consists of an activated carbon layer and a support layer. Activated carbon has developed pores, a large specific surface area, and high adsorption capacity. It is precisely because of this characteristic of activated carbon that it is widely used in the deep treatment of water, such as domestic water supply, deep treatment of wastewater treatment in the later stage (purified water), etc.Dust containing gas is powered by a fan and enters the tower at either positive or negative pressure. Due to the presence of unbalanced and unsaturated molecular attraction or chemical forces on the surface of activated carbon solids, when the solid surface comes into contact with the gas, it can attract gas molecules, causing them to concentrate and remain on the solid surface. The pollutants are then adsorbed, and the exhaust gas enters the equipment's dust removal system after passing through the filter, purifying the gas and achieving high altitude emission standards.1. High adsorption efficiency, large adsorption capacity, and wide applicability2. Easy maintenance without technical requirements3. Large specific surface area and good selective adsorption4. Activated carbon has the characteristics of a wide range of sources and low price5. High adsorption efficiency and strong ability6. Easy to operate and safeAfter using activated carbon for a period of time, it adsorbs a large amount of adsorbate and gradually saturates, losing its working ability. In severe cases, it will penetrate the filter layer. Therefore, activated carbon should be regenerated or replaced. Date：2024-01-12 -
