Explosion-proof analysis cabin with improved safety coefficient

Abstract

The invention discloses an explosion-proof analysis cabin with an improved safety coefficient, and aims to solve the technical problems that an existing explosion-proof analysis cabin can convey toxicgas in the environment into the cabin, which threatens the health of analysts in the explosion-proof analysis cabin. According to the technical scheme, the explosion-proof analysis cabin with the improved safety coefficient comprises a cabin body, and a fan used for ventilation is arranged on the side wall of the cabin body; a harmful gas detection module is arranged on the outer side wall of thecabin body, the harmful gas detection device is electrically connected with a control module, and the control module is connected with a sealing module used for sealing the fan and an air purification module used for adjusting the air quality inside the cabin body; the sealing module comprises a sealing frame, a sealing plate and a driving piece which are arranged on the inner side of the fan; and the air purification module comprises an air storage unit, a compression unit and a switch unit, the compression unit and the switch unit are both electrically connected with the control module, andthe cabin body is also provided with an air pressure balance module. The effect of improving the safety coefficient of the explosion-proof analysis cabin in a complex environment is achieved.

Description

technical field [0001] The invention relates to the technical field of gas analysis, in particular to an explosion-proof analysis cabin with improved safety factor. Background technique [0002] The explosion-proof analysis cabin is a new technology that became popular internationally in the mid-1980s. It integrates the combination, complete set, installation and application of industrial online instruments, and is first widely used in oil refining and chemical enterprises. The standardized and professional design of the on-site analysis house makes the on-site installation and maintenance of the analysis instruments more convenient, and provides a good operating and running environment for the instruments. While ensuring the required use environment and the accuracy of the analytical data, the service life of the analytical instrument has been improved, and it has been used more and more in the process equipment, and has been widely used in the safety performance of the en...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the above-mentioned explosion-proof analysis cabin is used in an environment with toxic gases, since the fan provided on the explosion-proof analysis cabin ventilates the interior of the cabin, the toxic gas in the environment will be transported into the hut, and when the harmful gas reaches a certain concentration, it will pose a threat to the health of the analysts inside the explosion-proof analysis hut, so it needs to be improved
