Specific description of a wet electric mist eliminator
2019-12-02
Wet electric mist eliminator is a new type of environmental protection equipment, mainly used to purify the fluid resistance of the minimum gas-liquid separation wet equipment, this equipment is mainly used in smelting flue gas acid, titanium dioxide calcination tail gas treatment, chemical plant all kinds of acid mist treatment. Electric mist eliminators are mostly used in sulfuric acid and other industries. Wet electric mist eliminators have multiple advantages. Today I will list the advantages of wet electric mist eliminators.
First, let's introduce the background of wet electric demister. In industrial production, if the gas contains steam of a certain substance, when it is cooled, the steam will condense into liquid or solid, or the gas will pass through a certain liquid at high speed, and the gas will be saturated with the steam of the liquid and entrain liquid droplets. Therefore, wet electric demister is needed to remove the maintaining liquid and solid particles suspended in the gas at this time.
wet electric mist eliminatorWork description: DC high-voltage electricity to the cathode line near the space gas ionization, dust particles charged in the electric field force under the action of moving and deposited on the surface of the dust collection anode, WESP with the dust collection anode surface water film or washing to remove dust.
wet electric mist eliminatorAdvantages:
Low resistance (<300Pa). Low operating and maintenance costs; service life of more than 30 years.
Widely used. Mainly used in electric power, metallurgy, boiler, chemical, waste incineration, building materials and other industries wet flue gas deep purification, ultra-low ultra-clean emissions.
Efficient. The removal rate of particulate matter such as PM2.5 is 85-95%; The chimney outlet dust can achieve the emission standard of 20mg/Nm3 and higher 5mg/Nm3; The removal rate of SO3 acid mist is 85-99%, and the corrosion of wet flue gas discharged through the chimney is greatly reduced. The removal rate of liquid droplets is 70-90%;
Comprehensive emission reduction of heavy metals and other pollutants. It can improve the cleanliness of flue gas emission and solve the problems of gypsum rain and white smoke.
Simple process: WESP and flue gas desulfurization system integrated design, new and transformation process is simple, compact structure, small footprint.
The secondary transformation can be installed after the desulfurization tower without changing the existing desulfurization and dust removal facilities, and can be operated stably for a long time.
