Heat exchanger

Abstract

The invention discloses a heat exchanger. The heat exchanger comprises a heat exchanger main body and an air inlet device, a water outlet device, a water return device, a smoke discharging device anda flue blocking plate which are correspondingly connected to the exchanger main body, wherein a circulating cavity is formed inside the exchanger main body, the exchanger main body consists of a frontsheet, middle sheets and a rear sheet, a plurality of middle sheets are sequentially connected between the front sheet and the rear sheet, the air inlet device and the flue blocking plate are connected to the end, deviating from the middle sheets, of the front sheet, and the water outlet device, the water return device and the smoke discharging device are connected to the end, deviating from themiddle sheets, of the rear sheet.

Description

technical field [0001] The invention relates to the technical field of heat engine heat exchange mechanical equipment, in particular to a heat exchanger. Background technique [0002] The boiler known as the "heart" of industrial production is a large energy consumer in my country, and it is also an important source of environmental pollution. High-efficiency special equipment mainly refers to the heat exchange equipment in the boiler. Up to now, conventional heat exchangers, exhausted flue gas If it is higher than 170°C, a large amount of CO2, NOX and a small amount of SO2 will be produced at the same time. These substances will be discharged into the atmosphere, which will cause the greenhouse effect and acid rain, and cause damage to the environment. At present, it is necessary to produce some special heat exchangers for boilers. Remove these harmful substances in the flue gas, improve thermal efficiency, and reduce environmental pollution. Contents of the invention ...
