Positive pressure explosion-proof house

Abstract

The invention discloses a positive pressure type anti-explosion house. The positive pressure type anti-explosion house comprises a house body, a horizontally arranged partition plate is arranged in the house body, and the partition plate divides the house body into an auxiliary floor at the upper side and a working floor at the lower side; an air inlet pipe is arranged on one side of the auxiliaryfloor, and an exhaust pipe is arranged on one side of the working floor; a through hole is formed in the partition plate, a vent pipe is arranged in the through hole in a matched mode, and both endsof the vent pipe extend into the auxiliary floor and the working floor separately; and a blower is further arranged at the upper end of the vent pipe, a sealing device is further arranged at the lowerend of the vent pipe and a temperature controller is further arranged in the working floor, and the temperature controller is connected with the sealing device in a control mode. The positive pressure type anti-explosion house has the advantages that the auxiliary floor and the working floor are arranged, electrical components or voltage devices are installed in the working floor, and the bloweris arranged in the auxiliary floor to blow air into the working floor; arc vertical plates are arranged in the working floor, and the arc vertical plates has a drainage function; and the sealing device of the vent pipe is arranged in the working floor, and the sealing device can be automatically controlled by the temperature controller.

Description

technical field [0001] The invention relates to the technical field of explosion-proof hut production, in particular to positive-pressure explosion-proof huts. Background technique [0002] Explosion-proof houses are generally used in flammable and explosive places. Installing transformers or electrical components in explosion-proof houses can effectively block flammable and explosive gases outside the explosion-proof house, preventing electric sparks and flammable gas generated by electrical components or transformers during work. Explosion phenomenon occurs on contact with explosive gas. [0003] The positive pressure type explosion-proof house is to pressurize the traditional explosion-proof house by filling inert gas, so that the pressure in the explosion-proof house is greater than the external pressure, so that the flammable and explosive gas from the outside cannot penetrate into the explosion-proof house, so that it can effectively block the flammable and explosive ...

AI Technical Summary

Problems solved by technology

[0003] The positive pressure type explosion-proof house is to pressurize the traditional explosion-proof house by filling inert gas, so that the pressure in the explosion-proof house is greater than the external pressure, so that the flammable and explosive gas from the outside cannot penetrate into the explosion-proof house, so that it can effectively block the flammable and explosive Gas, but electrical components or transformers will generate heat during the working process, so after a long time of work, the temperature in the explosion-proof room will gradually rise, and electrical components and transformers are easily damaged when working in a high temperature environment, which will cause circuit paralysis
