Novel indoor fire-fighting device with fire extinguishing function

Abstract

The invention discloses a novel indoor fire-fighting device with a fire extinguishing function. The novel indoor fire-fighting device with the fire extinguishing function comprises a fire-fighting room, an air purification room, a communication chamber, a water storage tank and a reaction room. The device is used for extinguishing fire by utilizing the principle that sodium bicarbonate and aluminum sulfate react to produce a large number of carbon dioxide gases; the reaction chamber is arranged for separately storing the two substances; the sodium bicarbonate is stored in a second storage box;a servo motor is arranged at one end of the second storage box; when a temperature sensor detects that the indoor temperature is too high, a programmable logic controller (PLC) automatically judges that a fire breaks out, and the servo motor runs at the moment, so that a sodium bicarbonate solution in the second storage box is poured into a first storage box so as to be mixed with an aluminum sulfate solution, and a large number of generated carbon dioxide gases enter the fire-fighting room through an air outlet branch pipe at the top end of the reaction room so as to extinguish fire of the fire-fighting room; and in addition, when the fire happened, a first electromagnetic valve is at an off state, and an air sucking pump runs at the same time so as to pump the gas in the fire-fighting room, so that an anaerobic condition of the fire-fighting room is accelerated.

Description

technical field [0001] The invention relates to a fire-fighting device, in particular to a novel indoor fire-fighting device with a fire-extinguishing function. Background technique [0002] Fire-fighting facilities refer to fixed facilities such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings. Automatic fire protection facilities are divided into electric system automatic facilities and water system automatic facilities. The indoor fire protection system refers to the facility system installed indoors to extinguish the initial fire in the building. It mainly includes indoor fire hydrant system, automatic sprinkler fire extinguishing system, water mist fire extinguishing system, foam fire extinguishing system, carbon dioxide fire extinguishing system, haloalkane fire extinguishing system, dry powder fire extinguishing system, etc. According to fire statistics, the installation of indoor fire protection systems is an effective a...

AI Technical Summary

Problems solved by technology

[0003] The existing indoor fire extinguishing systems are generally filled fire extinguishers or fire hydrant fire extinguishers, but it is easy to cause injuries to the extinguishers, and the fire extinguishing efficiency is not high. This kind of system is only suitable for use in ordinary buildings. In some special single buildings or It is necessary to install a set of high-efficiency fire-fighting devices in a single data room, and the current data rooms generally do not have air purification systems, and those with air purification systems are independent of the indoor fire-fighting system, and there is no centralized purification and fire protection
