Novel ash cleaning apparatus

Abstract

The invention relates to a new type of dust cleaning device, which is provided with a moving trolley, an air blowing box is arranged on the moving trolley, a reverse blower is arranged on the top of the blowing air box, and a pipe opening is arranged at the bottom of the blowing air box. The reverse blower is airtightly communicated with the pipe opening through a ventilation pipe, and a blower pulse valve is arranged on the ventilation pipe. The control part of the invention is simple and reliable, the injection positioning is accurate, and the injection time and injection interval period should meet the requirements of different working conditions.

Description

technical field [0001] The invention relates to a dust remover, in particular to a novel dust removal device. Background technique [0002] There are generally two ways to clean the airflow of the traditional bag filter: one is to use compressed air to blow the dust, and the other is to use the blower to blow the dust. Compressed air back-blowing soot cleaning is to use the principle of compressed air injection and secondary drainage to inject gas into the filter bag in an instant, shake off the dust adhering to the outside of the filter bag, and realize the regeneration of the filter bag. In the ash method, the filter bag is thoroughly cleaned due to the impact of the instantaneous airflow, but there are certain limitations. First, the user must have a compressed air source. Secondly, because the airflow for the secondary drainage is filtered airflow, once the filter bag If there is any damage, the dust will be directly blown into the inside of the filter bag, which accele...

Compressed air back-blowing soot cleaning is to use the principle of compressed air injection and secondary drainage to inject gas into the filter bag in an instant, shake off the dust adhering to the outside of the filter bag, and realize the regeneration of the filter bag. In the ash method, the filter bag is thoroughly cleaned due to the impact of the instantaneous airflow, but there are certain limitations. First, the user must have a compressed air source. Secondly, because the airflow for the secondary drainage is filtered airflow, once the filter bag If there is damage, the dust will be directly blown into the inside of the filter bag, which will speed up the clogging of the filter bag and make the filter bag invalid quickly

The traditional fan blowback cleaning generally has insufficient cleaning strength, especially the room-by-chamber blowback cleaning, which lacks the instant injection effect of compressed air blowback cleaning, and when blowing, there are too many offline filter bags, which reduces the Effective filtering area; commonly used dust collectors that use fan rotary spraying, due to the lack of pulsating valves and directional blowing mechanisms, the cleaning strength is not high enough

These all lead to the early failure of the filter bag and reduce the service life of the dust collector
