Wet dust collector is a device that makes the dust-containing gas in close contact with water, uses the inertia collision of water droplets and dust particles, or uses the full mixing effect of water and dust to capture particles to achieve the dust removal effect. Wet dust collectors can effectively remove liquid or solid particles with a diameter of 0.1 to 20 microns from the air stream, and at the same time, can remove some gaseous pollutants. It has the advantages of simple structure, small footprint, convenient operation and maintenance, etc. It can handle high-temperature and high-humidity airflow, reducing the possibility of fire and explosion.
There are many types of wet dust collectors. We generally provide spray, self-excited and venturi wet dust collectors, which are selected based on dust characteristics, gas concentration, humidity, viscosity, and collection efficiency. In general, the capture efficiency is related to the pressure loss of the system. The higher the required capture efficiency, the greater the pressure loss of the system, and the greater the energy consumption of the system.
Spray washing wet dust collector, the washing liquid is atomized into fine droplets and sprayed down uniformly through the nozzle, and the dust-containing gas enters from the lower part of the spray tower and flows from the bottom to the top. Collision and mutual agglomeration or agglomeration of dust particles greatly increase their weight and settle down by the action of gravity. The captured dust is gravity settled in the liquid storage tank to form a high solids-containing concentrated liquid at the bottom and periodically discharged for further processing. Part of the clarified liquid can be recycled, together with a small amount of supplemental clear liquid, through the circulation pump from the tower nozzle to the spray tower for spray washing. This reduces the consumption of liquid and the amount of secondary sewage treatment. The purified gas after spray-washing is removed from the top of the tower by removing small liquid droplets entrained by the gas through a demister.
Mainly used in: flammable dust, high temperature, high humidity, high viscosity dust, etc., including aluminum alloy grinding, polishing, shot blasting, chemical, pharmaceutical, metallurgy, casting and other industries.
由于水洗具有灭火性质，能够处理多种可燃性粉尘； ● Because water washing has fire extinguishing properties, it can handle a variety of combustible dusts;
由于气液接触同时发生传质和传热，因此既具有除尘作用，又具有烟气降温和吸收有害气体的作用； ● Because of gas-liquid contact, mass and heat transfer occur at the same time, so it not only has the function of dust removal, but also has the function of cooling the flue gas and absorbing harmful gases;
结构简单，占地面积小； ● Simple structure and small footprint;
维护成本低，不用更换过滤袋； ● Low maintenance cost, no need to change filter bag;
控制和操作简单； ● Simple control and operation;
运行安全； ● Operation safety;
