Wet-type vibrating-wire bipolar electrostatic coagulation deduster

Abstract

The invention relates to a wet-type vibrating-wire bipolar electrostatic coagulation deduster. The deduster comprises a shell, wherein one end of the shell is communicated with an air inlet pipe, the other end of the shell is communicated with an air outlet pipe, bottom of the shell is provided with a slurry bucket; bottom of the slurry bucket is provided with a slurry discharging port, the slurry bucket is connected with a sedimentation tank through an overflow pipe; the sedimentation tank is provided with a water pump which is connected with an atomizing nozzle through a circulating fluid pipe network; and the atomizing nozzle is arranged in the shell and on an air inlet channel of the air inlet pipe. The shell is further provided with a monolayer vibrating-wire grid and a multilayer vibrating-wire grid cooperating with each other and located between the atomizing nozzle and the air outlet pipe, wherein the monolayer vibrating-wire grid and the multilayer vibrating-wire grid are respectively connected with two electrodes of a DC high voltage power supply. The deduster has advantages of simple structure, low resistance, low energy consumption and large treatment amount for flue gas per unit area.

Description

technical field [0001] The invention relates to a wet vibrating wire dust collector, in particular to a wet vibrating wire bipolar electrostatic coagulation dust collector capable of efficiently trapping fine dust particles and water mist. Background technique [0002] The development of wet vibrating wire dust collector began in the late 1980s. For example, the Chinese invention patent No. 88100315.8 discloses a wet fiber grid dust collector. The dust collector has the advantages of small space occupied by unit processing air volume and low energy consumption. It is suitable for a wide range of dust concentrations, but its corrosion resistance is poor, and its service life is greatly reduced when it encounters corrosive fumes. In the 1990s, wet vibrating wire dust collectors using corrosion-resistant metal fibers appeared. For example, the Chinese invention patent No. 98229977.X disclosed a dust removal system for wet vibrating wire grids. Although the dust collector has th...

Problems solved by technology

Although the particle purification efficiency of the charged water mist vibrating wire washing dust collector has been improved, there are still the following shortcomings: First, the pre-charging method is adopted, and there is only Coulomb electrostatic attraction between the charged droplets and dust and the vibrating wire, but no electric field Second, the droplet is charged once, and the charge disappears when the droplet contacts the vibrating wire, so it is difficult to capture the dusty droplet that has not been separated after passing through the vibrating wire; thirdly, all of them are the same Polarly charged droplets, the repulsion between the droplets weakens the condensation effect
