Smoke prevention device for gas-mist mixed flow air curtain

Abstract

A smoke prevention device for a gas-mist mixed flow air curtain comprises a shell, wherein air inlets are formed in the front side of the shell, a water storage tank is arranged at the bottom of the shell, a mixing chamber used for gas-mist mixing is arranged in the shell, a first motor and a stirring impeller are fixedly installed in the mixing chamber, and a reservoir is arranged on the lower side of the mixing chamber and connected with the water storage tank through an automatic water supplementing valve; and mist inlets are formed between the mixing chamber and the reservoir, the mixing chamber communicates with an exhaust chamber, a second motor and a fan impeller are fixedly installed in the exhaust chamber, an air outlet is formed in the lower side of the exhaust chamber, and a control box is fixedly installed on the side face of the shell. The smoke prevention device can generate the gas-mist mixed flow air curtain, and gas flowing traversing the jet flow surface is prevented through the pressure difference inside and outside the curtain to block smoke diffusion. The water mist particles can be combined with and adhered to smoke dust particles in the air and absorb heat of a fire scene, so that the smoke prevention efficiency of the air-mist mixed flow air curtain is greatly improved.

Description

technical field [0001] The invention relates to the field of fire and smoke prevention, in particular to an air mist mixed flow air curtain smoke prevention device. Background technique [0002] Fire accidents are the most harmful and frequent disasters in modern society. When a fire occurs, the high temperature, toxicity and suffocation of the fire smoke are the direct causes of casualties. Therefore, the fire smoke has a great impact on the life safety of personnel. threaten. [0003] Existing fire and smoke prevention equipment includes fire masks, fire blower boxes, fire dampers, smoke-proof rolling doors and the like. Fire masks are time-consuming to wear and are difficult to popularize in public places such as schools, shopping malls, and Internet cafes. The fire-fighting fan box has a large volume, which is inconvenient to install and use, and the price is relatively high. The fire damper has a complex structure, inconvenient operation and requires a lot of mainten...

AI Technical Summary

Problems solved by technology

Fire masks are time-consuming to wear and difficult to popularize in public places such as schools, shopping malls, and Internet cafes

The fire-fighting fan box is large in size, inconvenient to install and use, and expensive

The fire damper has a complex structure, inconvenient operation and requires a lot of maintenance costs in the later period

The smoke-proof rolling door is difficult to seal and is rigidly blocked, which seriously hinders the entry and exit of escape personnel and firefighters

Traditional smoke prevention equipment has poor smoke prevention effect, high maintenance cost and will affect personnel escape
