Problems solved by technology

For the treatment of the flue gas discharged from the chimney, the best effect is the gas washing method (that is, the flue gas passes through water or aqueous solution), but this method is difficult to apply to the flue gas treatment of the height of the chimney due to the existence of the principle of the liquid connector At present, solid adsorption is mainly used to treat chimney flue gas
Industrial chimneys carry a lot of heat when they discharge flue gas. The existing method mainly uses water cooling to cool it down and then treat it. However, this treatment method increases the process, increases the cost, and does not effectively recover the heat. Utilization, the heat will be used for heating of residents in winter, but it will not be effectively used in summer, and the heat will have a lot of heat loss on the way to the heating equipment of residents

Abstract

The invention relates to a flue gas waste heat recycling environmental-friendly treatment device which comprises a flue gas washing chamber, an adsorption chamber, a heat exchange flocculation device,a centrifugal condensation device, a filtering chamber and a pure water recycling device. A flue gas is treated in a water washing mode by using a device of a specific structure, meanwhile heat of the flue gas is adopted to heat treatment water in two modes, then the temperature of the water is increased, and furthermore the water is purified in a gasification-condensation mode, so that only a very small amount of heat is consumed in gasification, and in a flue gas purification process, both the treatment water is recycled, and the heat is efficiently utilized.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to the field of recovering the waste heat of the flue gas while processing the flue gas, and in particular to an environmental protection treatment device for recovering the waste heat of the flue gas. Background technique [0002] The flue gas emitted by the chemical industry is the main source of air pollution. With the gradual advancement and further stringency of the environmental protection system, the treatment equipment for the flue gas discharged from industrial chimneys has become a hot spot for researchers. For the treatment of the flue gas discharged from the chimney, the best effect is the gas washing method (that is, the flue gas passes through water or aqueous solution), but this method is difficult to apply to the flue gas treatment of the height of the chimney due to the existence of the principle of the liquid connector At present, solid adsorption is mainly ...
