Industrial flue gas denitrification

The wet ESP is composed of two parts: the electrical equipment supplying high voltage direct current and the body of the ESP. The main structure of a wet electrostatic precipitator can be divided into the shell, gas distribution device, corona pole, precipitation pole, and washing device according to the function of each part structure. Wet electrostatic precipitator is mainly used in electric power, iron and steel, petrochemical, pharmaceutical, mining, textile and so on. it has good corrosion resistance, a convenient cleaning effect, no secondary dust, high efficiency of mist removal, and solves the problems of "gypsum rain" ammonia escape and aerosol.

All kinds of urban and rural domestic sewage are collected by the collection pipe network and transported to the integrated sewage treatment device, which is filtered and homogenized by the grid, treated by biological anaerobic and aerobic treatment, and then processed by membrane biofiltration and disinfection process. The effluent can reach the standard of reclaimed water reuse or be further treated as various industrial water sources. Can be used for residential areas, office buildings, and shopping malls.hotels, restaurants, agencies, schools, factories, and other domestic sewage and similar industrial organic wastewater treatment.

SNCR (selective non-catalytic reduction) flue gas denitration technology is an effective control measure for flue gas containing nitrogen oxides (NOx) after combustion. This technology is mainly used in coal-fired boilers of thermal power plants. The NOx in the treated flue gas is mainly composed of nitric oxide (NO) and nitrogen dioxide (NO2), of which NO accounts for about 95% of the total NOx emissions (volume concentration), while NO2 accounts for 5% (volume concentration).The core of SNCR technology is the use of ammonia (NH3) or urea as a reducing agent, which selectively reacts with NOx in a high-temperature environment. The reaction usually takes place in the furnace temperature range of 850 to 1100°C, so it is crucial to ensure effective injection of the reducing agent and good temperature control. In this way, SNCR technology can significantly reduce NOx emissions, improve combustion efficiency, and comply with increasingly stringent environmental standards.

Selective catalytic reduction (SCR) technology is an important means of controlling nitrogen oxide (NOx) emissions produced during the combustion process and is widely used in coal-fired boilers in thermal power plants. This technology effectively reduces the concentration of nitrogen oxides in flue gas, mainly targeting nitric oxide (NO) and nitrogen dioxide (NO2). Nitric oxide accounts for 95% of total NOx emissions, and nitrogen dioxide accounts for 5%.The core principle of SCR is to use a catalyst to reduce NO and NO2 to harmless nitrogen (N2) at a relatively low temperature using ammonia (NH3) as a reducing agent. This process is carried out under the action of a catalyst, which significantly improves the selectivity of nitrogen and effectively reduces the consumption of ammonia. When the molar ratio of NH3 to NOx reaches 1, the removal rate of NOx can be as high as 90%, while the amount of ammonia escape is controlled below 3mg/L.In practical applications, the operating conditions of the SCR system should be dynamically adjusted based on factors such as flue gas composition, temperature, and flow rate. Through real-time monitoring of flue gas components, the amount of reductant injection can be automatically adjusted to ensure that NOx emissions always meet regulatory requirements.
