Dust collector

Share to:


【Plate wet electric dust】


Technical Features:


1、High efficiency of dust removing. The equipment adopts the way of water spray cleaning dust on the surface of the electrode and not causes the secondary dust for the dust density for export below 5mg/Nm3;


2、High ratio resistance rate of dust catcher. As electric field area is washed by water spray, it can help with adhesion to surface of dusts. Especially when adhesion to surface of dusts, it accelerate the speed of dust particles in flue gas to heteropolar in order to effectively solve the problem of high resistance dust dust collecting;


3、High removal efficiency of PM2.5 fine dust and aerosols. It Can collect subsequent PM2.5 in flue gas desulfurization by wet process fine dust and aerosols. The removal rate is greater than ninety percent;


4、The solution of wet desulphurization gypsum rain and blue smoke acid mist environmental problems. The removal rate of SO3 is greater than ninety percent. The removal rate of spray is greater than seventy five percent;


5、High removal efficiency of mercury and high heavy metal in flue gas. The removal rate is greater than ninety percent.




【Electrical precipitator in lower temperature】


Technical Features: 


1、Reducing the smoke temperature, flue gas volume flow gets down;  


2、The flue gas temperature can reduce the dust resistivity in the best efficiency of range;  


3、Decreasing smoke temperature and improving electric breakdown voltage of precipitator, that can effectively prevent corona of dust separator, and reduce the secondary dust to improve the efficiency of dust removal; 


4、This equipment can remove most of the SO3 and reduce low temperature corrosion of tail flue gas. For the flue gas temperature has dropped below the dew point temperature, flue gas dust concentration is higher and the total surface area is large to provide a good condition of sulfuric acid mist condenses attached;  


5、Specification is small and the efficiency of dust control is high. This equipment adopted four electric and low temperature of dust collector which shows that dust emission concentration of the outlet filter can reach 20 ~ 30 mg/Nm3 even or lower.




【Electrostatic-bag dust collector】


Technical Features: 


1、This product is our company independent research and development of new high efficiency dust collector With high efficiency of dustremoval, low resistance, stable operation, higher dust removal efficiency and so on;


2、Front end electric field can collect around 80% of dust in order to greatly reduce load of back-end bag filter, filter bag and prolong the service life of pulse valve; 


3、Efficiency of dust removal is long-term stable below 20 mg/Nm3, which can meet dust emission requirements below 5mg/Nm3;


4、The equipment can be on-line overhaul and offline ash removal;  


5、It can greatly increase the rate of PM2.5 fine dust capture;


6、The operation resistance of the filter is lower than that of bag filter.




Brief  Introduction

Cohen Environment Protection Technology Co.,Ltd.is a integrated service providers holding the air pollution control by a listed company -- Guangdong Keda Clean Energy Co., Ltd. (Stock Code: 600499). It specializes in the power, chemical, building materials, metallurgy, garbage and biomass power generation industries such as flue gas dust removal, desulfurization and Denitration and other ultra-low emissions of environmental protection technology and equipment development, engineering design, project operations and general contracting and it is the national high-tech enterprise managing business of the third party. The company has established a national enterprise technology center, national engineering laboratory of flue gas multi-pollutant control technology and equipment, the national environmental protection industrial furnace flue gas Denitration engineering center, Jiangsu Province enterprise academician workstation, Jiangsu Province key laboratory of new-style environmental protection  and other research and development platforms, which have accessed to more than 110 national patents, which has built an area of 200000 m2 of eastern environmental protection industrial base and 130,000 m2 of western environmental industrialization base in Jiangsu Yancheng, Ningxia Shizuishan respectively.
