Industrial waste gas dedusting, purifying and waste heat utilizing device

Abstract

The invention discloses an industrial waste gas dedusting, purifying and waste heat utilizing device. The device comprises a deduster body; the bottom end in one side of the deduster body is provided with a flue gas inlet, the top end of the deduster body is provided with a gas outlet; a blowing and sucking chamber, a dust settling chamber, and a dust storage cavity are arranged in the deduster body from top to bottom; and a filtering layer and an electric dedusting layer are arranged in the dust settling chamber. The industrial waste gas generated by combustion is introduced into the deduster body through the flue gas inlet, then the waste gas goes through the filtering layer and the electric dedusting layer in the dust settling chamber to remove the dusts, and the separated dusts are collected and stored in the dust storage cavity. The environment is protected, and the damage to the human body is avoided. At the same time, an air outlet pipeline and a cold water tank are arranged on the gas outlet; the air outlet pipeline is coiled and tightly attached on the external wall of the cold water tank, thus the waste heat of industrial waste gas can be utilized to heat the cold water in the cold water tank, the waste heat is utilized, the energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a dust removal and purification device for industrial waste gas, in particular to a dust removal and purification device for industrial waste gas produced by burning coal or other substances, and belongs to the technical field of environmental protection machinery and equipment. Background technique [0002] The progress of mankind is inseparable from the development of industry. The development of industry has also brought a series of hidden dangers to human health. Heart disease and various respiratory diseases have become one of the biggest killers of human health. At present, most of the boilers, burners, steam engines and other equipment used in industry use coal, natural gas or diesel as raw materials, and even biomass fuels are getting more and more attention from human beings. It contains sulfur dioxide, carbon monoxide, dust, impurities, fine particles and other harmful substances. Once these substances are absorbed by...
