Rotational self-cleaned wet-method dust collector

Abstract

The invention discloses a rotational self-cleaned wet-method dust collector, belonging to the technical field of environmental-friendly equipment. The rotational self-cleaned wet-method dust collector comprises an air inlet, a cleaning chamber, a capturing filtering chamber, a cyclone chamber, a separation chamber, a drying chamber and an exhaust hole which are positioned on a same axis, arranged in sequence and are communicated and fixedly connected, wherein a cavity is formed inside the washing chamber; a spray tube water guide hole is formed in the top of the capturing filtering chamber; a rotational filtering cylinder, a spray capturing unit and a rotating shaft are arranged inside the capturing filtering chamber; a second blow-down hole is formed in the bottom of the capturing filtering chamber; overhaul holes are designed in one side or two sides of the capturing filtering chamber. The rotational self-cleaned wet-method dust collector has the characteristics of being simple in structure, powerful in function, small in resistance, good in energy conservation, good in environmental friendliness and good in treatment effect.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a rotary self-cleaning wet dust collector. Background technique [0002] With the increasingly severe global air pollution situation, the environmental protection requirements for various industrial flue gas and dust are getting higher and higher. As terminal treatment equipment, wet dust collectors have been widely used in domestic coal-fired power plants and coal-fired kilns. Wet dust collector is a new dust removal equipment used to deal with dust and fine particles. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in the gas. Ideal equipment for dust pollution. However, the wet dust collector is a large-scale equipment. The current general wet dust collector has problems such as bulky size, large water consumption, complicated construction, and high cost, so it is urgent to improve it. ...

Problems solved by technology

However, the wet dust collector is a large-scale equipment. Now the general wet dust collector has problems such as bulky size, large water consumption, complicated construction, and high cost, so it is urgent to improve it.

Existing various types of dust collectors are divided into two categories: dry filtration and wet washing. The dry method uses filter materials to filter and clean dust and exhaust gas particles. In order to meet the emission requirements, the filter materials often have very small pore diameters, which is the resistance of small pore filter materials. Reducing the filter area requires relatively large and overall equipment is relatively large, and at the same time increases the material and cost of the equipment; wet washing uses water and flowing dust gas to mix and collide, absorb, diffuse, dissolve and coagulate water molecules, in order to improve contact, Capture efficiency, increase the volume of the dust collector to increase the mixing of water and dust gas, this method increases the volume of the equipment and increases the material and cost of the equipment; in order to increase the collision between water and dust gas, the curved type is usually used , cobblestone packing, etc. to change the airflow direction, which increases the resistance of the gas; if the amount of water spray is increased to increase the washing effect, this will lead to excessive water consumption and increase the amount of sewage treatment
