Combustion-method flue gas purification device for remediating agricultural soil

Abstract

The invention belongs to the technical field of environment protection and in particular relates to a combustion-method flue gas purification device for remediating agricultural soil. Aiming at the problems of an existing combustion-method flue gas purification device that most design structures are relatively simple, purification treatment on flue gas is relatively coarse and the purification effect is relatively common, the invention provides the following scheme; the combustion-method flue gas purification device comprises a base, wherein supporting columns are welded at four corners of a top outer wall of the base; one top plate is arranged on the top outer walls of the four supporting columns; a filtering box and a gas pump are arranged at one side of the top outer wall of the top plate respectively; an input end of the gas pump is connected with the filtering box; a first filtering plate is arranged in the filtering box; a gas inlet hopper is arranged on an outer wall of one side, far away from the gas pump, of the filtering box. According to the combustion-method flue gas purification device, layered plates which are crossed at an equal distance are arranged so that the staying time of combustion flue gas in alkali liquid can be effectively prolonged, the alkali washing effect of an alkali washing box on the combustion flue gas is effectively improved and the combustionflue gas is conveniently subjected to rapid water cooling.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an incineration flue gas purification device for agricultural soil restoration. Background technique [0002] Incineration soil remediation generally refers to burning straw on farmland. The plant ash produced by burning straw is a good potassium fertilizer, and potassium fertilizer is a good fertilizer for crops. In the process of burning straw, the pests and eggs in the field can also be burned to death, which is beneficial to the growth of crops. However, the flue gas produced by straw incineration has serious pollution to the environment. The concentration of sulfur dioxide and inhalable particulate matter in the flue gas is several times higher than that in the air. ACCIDENT. [0003] Most of the existing incineration flue gas purification devices have a relatively simple design and structure, and the purification treatment of the flue gas is relatively ro...
