Abstract

A pulsive corona discharge equipment for desulfurizing, denitrating and dusting fume is composed of gas-state hydrocarbon feeling unit, gas current distributing plate unit, water vapor and ammonia gas activating unit, pulsive corona unit and by-product collecting unit.

Description

1. Technical field [0001] The invention belongs to the technical field of waste gas purification. In particular, it relates to a pulse corona discharge flue gas desulfurization, denitrification, reaction and dust removal integrated device for purifying sulfur dioxide and nitrogen oxides in flue gas. 2. Background technology [0002] The pulse corona discharge flue gas purification device generally consists of the following five main unit structures: flue gas humidification and cooling tower, gas ammonia dosing device, pulse high voltage power supply, pulse discharge plasma reactor, by-product collection device, ammonia gas and Sulfur dioxide and nitrogen oxides in the exhaust gas react to form ammonium sulfate and ammonium nitrate, which are easily deposited in the pipeline between the pulse discharge plasma reactor and the by-product collector. To solve the deposition problem of ammonium sulfate and ammonium nitrate, it will increase Equipment for cleaning ammonium sulfate...
