Introduction to the principle of washing dedusting equipment
Washing type dust removal equipment includes water bath type dust removal equipment, foam dust removal equipment, venturi tube dust removal equipment, water film type dust removal equipment, etc.
Water bath type dust removal equipment principle of work is in the dust removal equipment in the inland waters through nozzle spray mist, when protecting gas space through the mist, because of dust particles and the collision between droplets, intercept and cohesion function, dust particles with the liquid drop down.
Bath type dust removal equipment advantages: with a small aperture and orifice, can handle high dust concentration of flue gas and won't cause congestion, and filtered water can be recycled, until the washing liquid, concentration to achieve very high concentration in the simplified water treatment facilities; Disadvantages: the equipment is large and the ability to process fine dust is low. Therefore, this type of dust collector is often used to deal with smoke with high concentration of dust.
洗涤式除尘设备包括水浴式除尘设备、泡沫式除尘设备，文丘里管除尘设备、水 膜式除尘设备等，下面以水浴式为例简介：
水浴式除尘设备工作原理是在除尘设备内水通过喷嘴喷成雾状，当含尘烟气通过雾状空间时，因尘粒与液滴之间的碰撞、拦截和凝聚作用，尘粒随液滴降落下来。
水浴式除尘设备优点：内设很小的缝隙和孔口，可以处理含尘浓度较高的烟气而不会导致堵塞，而且过滤水可以循环使用，直至洗涤液中物质浓度达到相当高的浓度为止，简化了水处理设施；缺点：设备体积较大，处理细粉尘的能力较低。所以该类型除尘器常用于处理粉尘径大含烟浓度较高的烟气
