AI Technical Summary

Problems solved by technology

Although the existing positive pressure cabinets are well sealed, a small amount of hydrocarbon gas will still be mixed into the cabinet. During the exhaust process, these hydrocarbon gases will be emptied directly with nitrogen, which will cause certain pollution to the atmosphere.

Abstract

The invention discloses a gas exhaust device for an explosion-proof positive pressure cabinet. The gas exhaust device comprises a main cabinet body (1) and a gas exhaust cabinet body (3), the main cabinet body (1) is internally provided with a horizontally-arranged first partition plate (1.1), the first partition plate (1.1) divides the interior of the main cabinet body (1) into a mounting bin (1.2) at an upper layer and a transition bin (1.3) at the lower layer, a first gap (1.11) is formed between one side of the first partition plate (1.1) and the inner wall of the main cabinet body (1), and a first sealing device (4) used for sealing the first gap (1.11) is arranged in the transition bin (1.3). The device has the advantages that during gas exhausting by the device, the mixed gas to bedischarged can be filtered so that the hydrocarbon harmful gas in the mixed gas can be absorbed, and then external atmospheric pollution can not be caused.

Description

technical field [0001] The invention relates to the technical field of electrical explosion protection, in particular to an exhaust device for an explosion-proof positive pressure cabinet. Background technique [0002] With the rapid development of coal oil chemical industry, metal smelting, chemical pharmaceutical and other industries, explosion-proof positive pressure cabinets are more and more widely used in system control. How to accurately use the positive pressure explosion-proof controller in the explosive gas hazard occasion. Because electrical equipment inevitably generates electric sparks or forms a hot surface during work, once they meet with the explosive gas mixture on site, it will cause an explosion accident, endangering the property and life safety of users. Existing explosion-proof positive pressure cabinet. During the use of the explosion-proof positive pressure cabinet, it is necessary to ventilate the cabinet frequently, so as to ensure that the tempera...
