Problems solved by technology

[0003] In the prior art, traditional plate heat exchangers are generally used to recover the heat energy in the flue gas. Since the flue gas contains large particles, it is easy to foul when passing through the traditional heat exchanger, and the heat exchange effect of the heat exchanger will be reduced. severely affected

Abstract

The invention relates to a smoke recycling welding-type plate-type heat exchanger, comprising a smoke channel and a cold medium channel, which are welded together and are divided by a plurality of plate sheets, wherein the smoke channel comprises a smoke inlet, a smoke outlet, a smoke channel exhausting opening and a dirt discharging opening. The cold medium channel comprises a cold medium inlet, a cold medium outlet, a cold medium channel exhausting opening and a dirt discharging opening; and the smoke inlet is located at the upper part of the plate-type heat exchanger. The smoke recycling welding type plate-type heat exchanger has the characteristic of small size, is easy to wash and solves the problems that the traditional plate-type heat exchanger is easy to scale and is not easy to wash.

Description

technical field [0001] The invention relates to a plate heat exchanger, in particular to a flue gas recovery welded plate heat exchanger. Background technique [0002] It is well known that the humidity of the flue gas is high, the temperature changes greatly, the flow rate is large, and there is a lot of dust. How to efficiently recover the heat energy in flue gas is an important issue in recent years. [0003] In the prior art, traditional plate heat exchangers are generally used to recover the heat energy in the flue gas. Since the flue gas contains large particles, it is easy to foul when passing through the traditional heat exchanger, and the heat exchange effect of the heat exchanger will be reduced. severely affected. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a flue gas recovery welded plate heat exchanger. [0005] Technical scheme of the present invention is as follows: [0006] A flue gas...
