Abstract

The invention discloses coal cinder cooling waste heat recovery equipment. By means of the coal cinder cooling waste heat recovery equipment, complete cooling of medium-high temperature coal cinders can be achieved, waste heat can be recovered while the medium-high temperature coal cinders are cooled, high efficiency and energy saving are achieved, the coal cinder cooling waste heat recovery equipment can be effectively used for cooling the medium-high temperature coal cinders generated in the thermal power plant coal-fired boiler production process, and waste heat recovery can be achieved.

Description

technical field [0001] The invention relates to the technical field of cooling waste heat recovery, in particular to a coal slag cooling waste heat recovery device. Background technique [0002] For the cooling problem of medium and high temperature coal slag generated in the production process of coal-fired boilers in thermal power plants, the current solution is mainly water cooling or air-water combined cooling. Although the cooling effect is good, the waste heat recovery effect after cooling through heat exchange is not ideal, causing resources waste. Contents of the invention [0003] The purpose of the present invention is to aim at the technical defects existing in the prior art, and to provide a coal slag cooling waste heat recovery equipment, which is a kind of air-cooled medium-high temperature coal slag, which effectively cools the medium-high temperature coal slag, and also High-efficiency and energy-saving equipment that can recover waste heat. [0004] The ...
