Tube bundle type cooler soot deposit cleaning device

Abstract

The invention discloses a tube bundle type cooler soot deposit cleaning device which comprises a cooler machine body, wherein a plurality of rows of cooling tubes are arranged in the cooler machine body; a jetting tube is fixed above a space between the two rows of cooling tubes; each jetting tube is provided with a nozzle which is corresponding to the position of the tube mouth on the top of the corresponding cooling tube one by one; and one end of the jetting tube extends out of the cooler machine body and is communicated with an air supply system. The tube bundle type cooler soot deposit cleaning device has the advantages of simple structure, small energy consumption and low cost, is convenient to install and use and is convenient to operate and maintain, and instant expansion generated when air is compressed is used for impacting the soot deposit, raise the dust and take away the dust so as to prevent generation of scales.

Description

technical field [0001] The invention mainly relates to the treatment of ash accumulation in a tube-bundle cooling device for industrial high-temperature flue gas, in particular to a cleaning device for ash accumulation in a tube-bundle cooler. Background technique [0002] In industrial applications, tube bundle coolers are often used to cool dusty high-temperature flue gas; tube bundle coolers are mainly composed of tube bundles, reverse blowers and supports; tube bundles include intake horns, ash hoppers, cooling pipes, side beams and beams, etc. . The high-temperature flue gas enters the cooling tube through the inlet horn, and the cold air is blown into the tube bundle by the reverse blower. Through the tube bundle, the high-temperature flue gas and air perform heat exchange to achieve the purpose of cooling. The cooled high-temperature flue gas enters the pipe through the air outlet on the ash hopper and is discharged. [0003] However, in practical applications, due ...

Problems solved by technology

[0003] However, in practical applications, due to the precipitation of dust or gas in the flue gas when it is cooled, it is easy to stick to the inside of the pipe wall; especially the flue gas containing viscous substances such as tar, after a long period of cooling operation, deposits In the end, fouling is easy to occur, which will reduce the ventilation area of ​​the pipeline and increase the resistance, which will affect the flow and cooling of the airflow; in severe cases, it will cause blockage, affect the operation of upstream and downstream equipment, and cause accidents

Scaling occurs, only after the machine is shut down, it is manually cleaned through openings, the working environment is harsh, the process is cumbersome, and the workload is large; or it is mechanically cleaned, there are many faults and high energy consumption

If it is dangerous gas or dust, it will cause gas or dust leakage, resulting in personal injury or even accident
