Abstract

The invention discloses a multifunctional mist-carrying air curtain smoke prevention device which comprises a shell, a motor, an impeller, a wind shield, a filter block, an atomizing spray head, a water storage tank, a spray head controller, a control box and a smoke alarm. An air inlet is formed in the front side of the shell, a first air outlet is formed in the rear side of the shell, the first wind shield is arranged in the middle inside the shell, the water storage tank is fixedly installed at the bottom of the shell, the first motor and the impeller are fixedly installed between the air inlet and the first wind shield, the filter block is detachably mounted between the first air outlet and the first wind shield, and the atomizing spray head is connected with the water storage tank through a connecting pipe. According to the multifunctional mist-carrying air curtain smoke prevention device, the first motor is started through mobile phone software to drive the impeller to rotate, meanwhile, the atomization spray head is started to spray water mist, the smoke prevention device generates mist-carrying curtain-shaped airflow at a certain speed, and smoke spreading is efficiently blocked. At ordinary times, air enters from the air inlet, is filtered layer by layer by the filter block and is discharged from the first air outlet, so that the air purification function is realized.

Description

technical field [0001] The invention relates to the field of fire and smoke prevention, in particular to a multifunctional smoke prevention device with mist-filled air curtain. Background technique [0002] With the acceleration of my country's modernization process, the vigorous development of urban construction and the continuous emergence of super high-rise buildings. Of the 235,000 high-rise residential buildings nationwide, 46.2% are not equipped with automatic fire protection facilities. Due to its huge size, complex functions, and relative concentration of personnel and materials, super high-rise buildings can cause fires if they are not careful, causing serious casualties and economic losses. The smoke in the fire of super high-rise buildings is an important factor that endangers people's lives. When a fire occurs, the high temperature, toxicity and suffocation of the fire smoke are the direct causes of casualties, so the fire smoke poses a great threat to the safe...
