AI Technical Summary

Technical Problem

A common problem in ash transmission system in thermal power plants is poor loading of the ash bucket. The main reason is that the gasification air duct is blocked, resulting in poor dry ash flowability in the ash bucket, increasing feed time, reducing dry ash temperature, and thus making transportation more difficult. .

Method used

It has designed a kind of anti -air -to -air air -based air device, including gasification of air tubular and gasized air tubes. By introducing ash compressed air as auxiliary gas sources, automatically judge and switch the gasification air system, and use pressure switch and pneumatic valves to achieve pairs. Automatic dredging of gasized wind tube.

Benefits of technology

Effectively prevent the blocking gas tube, ensure the liquidity of dry ash in the ash, ensure smooth gray, reduce hidden safety hazards, and improve the stability and efficiency of the ash -mouting system.

Abstract

The invention discloses an anti-blocking gasified air device which comprises a gasified air main pipe and gasified air branch pipes, the gasified air main pipe is communicated with a plurality of gasified air branch pipes, the middle of the right side of the gasified air main pipe is communicated with an air inlet pipe, and the middle and the other end of the air inlet pipe are connected with a heater and a plurality of groups of gasified fans respectively. The invention relates to the technical field of ash conveying devices, ash conveying compressed air is introduced to serve as an auxiliary air source of gasification air, and when the gasification air branch pipe is not smooth, the first connecting pipe is blown and dredged and then is switched into an original gasification air system; and automatic judgment and switching are carried out, the system can automatically judge the blockage condition of the first connecting pipe according to the gasification air pressure, an auxiliary air source is automatically switched for purging, and the system is automatically switched to an original gasification air system after purging dredging.
