FRP electric demister
With the continuous development of industry, China's air pollution is becoming more and more serious, especially the dust pollution in the air, which has caused severe haze and climate in recent years, endangering human health. Obviously, curbing the discharge of pollutants is one of the primary problems of industrial development today. In this way, it promotes the use of demisters in industrial production, and further enhances the development and research of electric demisters.
As we all know, the purification principle of the electric demister is: the strong electric field formed between the cathode and the anode is used to ionize the air molecules, and a lot of electrons, positive and negative ions that occur momentarily charge particles such as dust and mist droplets passing through the electric field. The action of the electric field force makes a directional movement to the cathode and anode, so particles such as dust and mist droplets are collected on the cathode and anode, thereby purifying the discharged flue gas.
The existing defogger mainly has the following shortcomings: 1. The air flow of the electric defogger is unevenly distributed, which means that there are high and low speed areas in the electric field, and there are vortices and dead angles in some parts. The power of acid mist removal is far from enough to compensate the reduction of power at high flow rate. In addition, high-speed airflow and vortex flow will cause scouring, which causes the acid mist on the anode tube to fly twice. Due to the poor airflow distribution, the power of the electric demister can be reduced by more than 20-30%, and the airflow is unevenly distributed to form the cathode line And the structure shakes fiercely, the electric field spark discharges frequently, and the electric field voltage is unstable, which affects the power of defogging. 2. In order to clean the dust and mist droplets accumulated on the cathode line and the anode tube, it is necessary to add an independent spraying device inside the casing. And placed in the upper part of the cathode area and the anode area, it is obvious that the internal structure of the current electric demister is more messy. In addition, the spray pipe of the independent spray equipment in the prior art is installed above the cathode bearing structure, and the spray rinse liquid is connected to clean the cathode line and the anode pipe. Many, complicated and messy structure; otherwise, the spray liquid flow is easily blocked by the cathode bearing structure, etc., which affects the coverage of spray cleaning and reduces the spray cleaning effect.
