An intelligent micro-pressure explosion-proof positive pressure cabinet

Abstract

The invention discloses an intelligent micropressure and explosionproof positive-pressure cabinet. The intelligent micropressure and explosionproof positive-pressure cabinet comprises a main cabinet body, an inflatable cabinet body and a discharging cabinet body, wherein the main cabinet body is partitioned into an upper-layer installation bin and a lower-layer transition bin by a first partitionplate, a first sealing device is arranged in the transition bin, the inflatable cabinet is partitioned into an upper-layer inflatable bin and a cooling bin by a second partition plate, a first inflatable pipe is arranged at one side of the cooling bin, a first electric valve is arranged on the first inflatable pipe, a second electric valve is arranged on the second inflatable pipe, the dischargingcabinet body is partitioned into an upper-layer first discharging bin and a second discharging bin by a third partition plate, a through hole is formed in the third partition plate, and an X-moleculesieve filtering cylinder and an active carbon absorption filtering cylinder are arranged in the through hole. The intelligent micropressure and explosionproof positive-pressure cabinet has the advantages that air exchange is performed according to a temperature in the cabinet, mixed gas to be discharged can be filtered during discharging, hydrocarbon harmful gases in the mixed gas is absorbed, and no pollution to external atmosphere is generated.

Description

technical field [0001] The invention relates to the field of electrical explosion-proof technology, in particular to an intelligent micro-pressure 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 temper...

AI Technical Summary

Problems solved by technology

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