Positive-pressure sealing anti-blocking soot blower of waste incineration boiler

Abstract

The invention discloses a positive-pressure sealing anti-blocking soot blower of a waste incineration boiler. The positive-pressure sealing anti-blocking soot blower comprises a soot blower pipeline, a motor, a scraper and a baffle ring, the motor is installed on the outer surface of the bottom end of the left side of the soot blower pipeline, a sealing sleeve is installed on the outer surface of a shaft rod, a knife rest is installed on the outer surface of the top end of a supporting rod, a first sealing ring is installed on the outer surface of the right end of the soot blower pipeline, a fixing frame is installed above a baffle ring, a first baffle is installed on the surface of the inner side of the fixing frame, a second sealing ring is installed on the outer surface of the left side of the first baffle, a second baffle is installed on the left side of the baffle ring, and a third sealing ring is installed on the outer surface of the right side of the second baffle. According to the positive-pressure sealing anti-blocking soot blower of the waste incineration boiler, gas and dust are prevented from leaking outwards through the baffle ring, the inner wall of a pipeline is cleaned through the scraper, pipeline blocking caused by dirt such as dust is avoided, and the scraper is convenient to replace after being installed.

Description

technical field [0001] The invention relates to the technical field of waste incineration boilers, in particular to a positive pressure sealing anti-blocking soot blowing device for waste incineration boilers. Background technique [0002] When the boiler works for a long time, dust will accumulate on the inner wall of the boiler. When wrapping, the heat absorption will inevitably be affected, resulting in a reduction in the thermal efficiency of the boiler, so the soot blowing device will be used; [0003] However, when the existing soot blowing devices on the market are in use, if the soot blower is used for a long time, dirt will accumulate in the soot blowing pipe, which will cause the soot blowing pipe to block and affect the cleaning effect. There is a certain gap at the joint of the furnace wall, and the gas and dust in the furnace will leak out from the gap during the expansion and contraction of the pipeline. Therefore, a positive pressure sealing anti-blocking soo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a positive pressure sealing anti-blocking soot blowing device for a waste incineration boiler, so as to solve the problem that the existing soot blowing device on the market proposed in the above-mentioned background technology is used if the soot blower is used for a long time. Dirt will accumulate in the soot blowing pipe, which will block the soot blowing pipe and affect the cleaning effect. There is a certain gap between the soot blower pipe and the furnace wall, and the gas and dust in the furnace will leak from the gap during the expansion and contraction of the pipe. out of question
