Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to solve the three major problems existing in the existing electrostatic purification method, ① the volume and floor area of ​​the equipment are quite large, so large that some units do not have the conditions for use; ② the electric field intensity and the purification rate drop sharply, Most of them will fail in a short period of time; ③At present, there is still no good way to clean the plates, resulting in many devices that cannot work even though they are in the working position

If adopting spray droplet then can be sprayed by infusion pipe 3 and nozzle 4, if use solid particle as particle flow, then set inlet to introduce in addition. Corona electric fields with opposite polarities are set on the path or entrance of the polluted airflow and liquid droplets or particle flow respectively. The two corona electric fields with opposite polarities can be combined into one place, or can be divided into two places or at different parts. E...

Abstract

This invention relates to a kind of apparatus and method for purifying flue dust and particulate, which can bring in spray liquid drop or corpuscular flow, and then set corona electric field of antipole in the path between contaminative airflow and the liquid drop or the corpuscular flow. When flue dust, particulate and liquid drop or corpuscular flow running through the corona electric field, they will charge the positive charge and negative charge respectively, and they will attract and impact each other. Then contaminative granules absorb in the particle of liquid drop or corpuscular flow and deposit with it, and yet clean air will be separated from the dust flow then driven out. By \ general treatment, the contaminative granules can be separated from the liquid drops or the granules of corpuscular flow, so that the liquid drops or the granules of corpuscular flow can get into recycled use. This invention has the advantages of scientific usage, reasonable projection, small apparatus volume and low cost, so it's a thrifty and applicable apparatus and method with high efficiency and blue-chip technical characteristic for environment protection.

Description

Technical field: [0001] The invention relates to a method and equipment for purifying smoke and dust in the field of environmental protection. Background technique: [0002] At present, among various purification methods of smoke and dust, the electrostatic purification method has the highest efficiency and the most economical operation. However, the purification equipment of various electrostatic methods all rely on electrodes of different forms to adsorb pollutant particles, which fundamentally restricts the application and development of electrostatic purification methods. [0003] (1) Due to relying on electrode adsorption for purification, limited by the driving speed of the electrostatic field, the speed of the dusty airflow can only be very low, generally not exceeding 2M / s, which increases the volume and floor area of ​​the purification equipment and greatly increases the cost , so that it cannot be applied in many cases. [0004] (2) Due to the accumulation and ad...
