AI Technical Summary

Technical Problem

Existing explosion-proof dust removal equipment lacks proactive handling capabilities in terms of explosion prevention, cannot effectively suppress the risk of explosion, and poses the risk of localized high-temperature areas and secondary combustion hazards caused by high-temperature airflow.

Method used

By employing a combination of vent design and sleeve on the air intake pipe to form an annular exhaust channel, and combined with the guidance of inert gas, a multi-stage purification system is constructed, including an adsorption bed and dust removal filter bags. Through inert gas dilution and heat exchange, the potential causes of explosion are actively eliminated.

Benefits of technology

It achieves active fire suppression of high-temperature sparks and multi-stage dust purification, reducing the risk of explosion, ensuring a safe and stable dust removal environment, and avoiding localized high temperatures and secondary combustion.

Abstract

This invention discloses an explosion-proof cavity integrated particulate adsorption dust removal device, belonging to the technical field of separation and dust removal equipment. It includes a dust collection box, with upper and lower partitions installed at intervals inside, dividing the interior of the dust collection box from top to bottom into an exhaust chamber, a dust collection chamber, and a dust-to-be-removed chamber. An explosion-proof dust removal device is installed between the dust collection chamber and the dust-to-be-removed chamber. The explosion-proof dust removal device includes an adsorption bed for filling the dust collection chamber with adsorption medium, an air inlet pipe communicating with the dust-to-be-removed chamber on the lower side of the dust collection box, and several radially penetrating air holes evenly distributed on the air inlet pipe. This invention, through the cooperation of the guiding air pipe and the sleeve, allows nitrogen to form a circumferential air curtain in the exhaust channel area, actively dispersing the high-temperature, sparking, dust-laden airflow and diluting the oxygen concentration. A slightly positive pressure environment is created in the filtration area to isolate external air infiltration, fundamentally eliminating the accelerant conditions in the cause of an explosion.
