A positive and negative pressure synergistic pulse cleaning device with explosion suppression function

Abstract

The invention discloses a positive and negative pressure synergistic pulse dust cleaning device with explosion suppression function, which comprises an upper pulse valve, a compressed air source, a filter cartridge and a dust collector box, and a plurality of upper pulse valves are arranged in the dust collector box And the filter cartridge, the upper pulse valve is installed above the top opening of the filter cartridge and connected to the compressed air source outside the dust collector box through the air pipe. The dust discharge device is installed at the bottom of the dust collector box, including the lower pulse valve and the vacuum chamber. , a vacuum generator, and a pulse controller, the lower pulse valve is arranged below the bottom surface of the filter cartridge and connected to the vacuum chamber; part of the bottom surface of the filter cartridge is a weak panel, and the weak panel is located in the vacuum chamber; the vacuum chamber is connected to the dust removal chamber in turn through the air pipe Vacuum generator and compressed air source outside the device box; the pulse controller is connected to the upper pulse valve and the lower pulse valve in turn. This positive and negative pressure cooperative pulse cleaning device with explosion suppression function can effectively suppress dust from flying , to achieve active explosion suppression; to slow down the explosion power and enhance the performance of passive explosion suppression.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a positive and negative pressure cooperative pulse dust removal device with an explosion suppression function, and belongs to the technical field of internal filter dust removal under explosive dust conditions. Background technique [0002] The dust removal process of the filter type dust removal system is the basic link of the dust removal work. The commonly used dust removal methods mainly include: air flow blowback, pulse injection and vibration dust removal. The airflow blowback method has simple structure, convenient operation, and uniform dust removal effect, but the backflush process will interrupt the dust filtration; the vibration dust cleaning method generally drives the eccentric wheel by the motor to shake the filter cartridge, and vibrates the collected dust. This method is the most effective for cleaning dust, and there is no dead angle in cleaning dust, but it needs to incr...

Problems solved by technology

However, these explosion venting methods will inevitably discharge a large amount of flammable mixture into the outside world, causing external disasters

It can be seen that even if active explosion suppression measures are taken, the dust removal system for explosive dust cannot completely eliminate the explosion hazard.
