High-temperature coom washing and recovering system

Abstract

The invention discloses a high-temperature coom washing and recovering system. The system comprises a cyclone dust collector, a washing tower and a drying tower, wherein the cyclone dust collector comprises a barrel body, a cone body and a dust bucket which are arranged from top to bottom; a coom inlet is formed in the sidewall of the barrel body, and a coom outlet is formed in the top part of the barrel body; a first water pipe is arranged around the outer wall of the cone body; the washing tower comprises a deacidification chamber, a dealkalization chamber and a water washing chamber which are formed from top to bottom; and the drying tower comprises a waterproofing breathing film, a plurality of drying layers and a plurality of water condensing nets, wherein the waterproofing breathing film, the drying layers and the water condensing nets are horizontally arranged from top to bottom. With the adoption of the system, micron-sized solid dust (such as sandy dust and coal dust), sticky liquid microspheres (such as oily fume and dust-haze) and soluble gas (such as hydrogen sulfide, nitric oxide and hydrogen chloride) in the coom can be effectively removed; the heat of high-temperature coom can be fully exchanged, so that the heat energy of the high-temperature coom can be utilized to the maximum, and as a result, a good dust removing effect is achieved; and in addition, the dust-removed gas can be dried, thus the resource is saved, and the environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of air purification. More specifically, the present invention relates to a high-temperature soot cleaning and recovery system. Background technique [0002] The high-temperature soot discharged from coal-fired power plants contains a large amount of insoluble dust, soot particles, and soluble gases (such as hydrogen sulfide, nitrogen oxides, hydrogen chloride, etc.). If these substances enter the atmosphere, they will not only seriously pollute the air, but also pass through Different ways enter the human body, some directly cause harm, and some have cumulative effects, which will seriously endanger human health. In addition, if high-temperature soot is directly discharged, the heat is often ignored, resulting in waste of resources. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be...
