Abstract

The invention discloses an electric coagulation spray dust removal system which comprises a tower. A gas inlet pipe is connected to the bottom of the tower, an exhaust pipe is correspondingly connected to the top of the tower, an electric coagulation device with an alternating electric field is mounted on the gas inlet pipe, a high-pressure dust remover with a static electric field is mounted in the tower and is positioned above the gas inlet pipe, a plurality of sprayers are mounted above the high-pressure dust remover with the static electric field and are connected with an absorption liquid pipeline, a valve is arranged on the absorption liquid pipeline and is connected with an absorption liquid delivery pump, the absorption liquid delivery pump is connected with an absorption liquid distribution pond by a pipeline, a demister is mounted above the sprayers, and a liquid outlet is formed in the bottom of the tower. The electric coagulation spray dust removal system has the advantages that the purpose of synchronously removing fine particulate matters such as PM (particulate matter) 2.5 particulate matters in coal-fired flue gas can be achieved by the electric coagulation spray dust removal system, and the electric coagulation spray dust removal system is good in dust removal effect and low in cost.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an electrocoagulation method spray dust removal system. Background technique [0002] At present, the treatment of PM2.5 dust particles in coal-fired flue gas in China mostly relies on equipment such as electrostatic precipitators, bag-type precipitators or electric bag composite precipitators. In electrostatic dust removal, through the ionization effect of strong electric field, large particles are removed after being charged with free electrons, but because PM2.5 is in the mixed area of ​​on-site charging and diffusion charging, the charging ability is very poor and it is difficult to remove; bag type dust removal It has a good removal effect on fine particles, but the bag type dust collector is frequently cleaned, which reduces the service life of the filter bag and increases the difficulty of stable operation management; the electric bag composite...
