FIREPROOF AND EXPLOSION-PROOF DEVICE AND METHOD FOR BOX DEHUMIDIFICATION, WATER REMOVAL AND CONDENSATION PREVENTION

Provided in the present invention are a fireproof and explosion-proof device and method for box dehumidification, water removal and condensation prevention. The device comprises: a box housing with a mounting hole, an air duct module, and a control module, wherein the air duct module is composed of an air duct, a filter screen, a pressure ring and a threaded sleeve, and the air duct module is fixed in the mounting hole of the box housing; and the control module is screwed to the threaded sleeve and is fitted to an end face of the air duct module. The control module is composed of a fan, a labyrinth exhaust block, a main control PCB module, a power supply, an internal temperature and humidity module, and an external temperature and humidity module. According to internal and external measured temperature and humidity data, other computational data and the current time moment, the control module controls the fan to actively exhaust air from a box or to be in standby mode, so as to exhaust moisture or water from
