Abstract

The invention discloses a blockage clearing device for a multi-air-preheater system and a blockage clearing method of the blockage clearing device, relates to the technical field of air preheater cleaning, and aims to solve the problem that heat exchange fins in existing air preheaters are prone to soot impurity adhesion and difficult to clear along with long-time use. A first anti-blocking device is installed on one side of a heat exchange rotor, a first lead screw is rotationally installed at the upper end of the interior of the first anti-blocking device, a sand-containing spray head is fixedly installed below a first sliding block, and a sand storage barrel and an air compressor are arranged in a first fixing box. A recovery groove is formed in the lower end of the interior of the first anti-blocking device, a second anti-blocking device is installed on the other side of the heat exchange rotor, second lead screws are rotationally installed at the upper end and the lower end of the interior of the second anti-blocking device, a rotating base is fixedly installed at one end of a second sliding block, a cleaning head is rotationally installed in the rotating base, and a second fixing box is fixedly arranged on one side of the second anti-blocking device.

Description

technical field [0001] The invention relates to the technical field of air preheater cleaning, in particular to a blockage removal device and a blockage removal method for a multi-air preheater system. Background technique [0002] The air preheater is the heating surface where the flue gas in the flue at the tail of the boiler preheats the air before entering the boiler to a certain temperature through the internal cooling fins. It is a device used to improve the heat exchange performance of the boiler and reduce energy consumption. Air preheaters are generally divided into three types: plate type, rotary type and tube type. The rotary air preheater will rotate slowly during operation, and the flue gas will enter the flue gas side of the air preheater and then be discharged, while the flue gas The heat carried in the air preheater will be absorbed by the cooling fins in the air preheater, and then the air preheater rotates slowly, and the cooling fins move to the air side, ...
