Description

Technical Field

[0001] This utility model relates to the technical field of smoke exhaust equipment in public places, specifically a fire-fighting smoke exhaust filtration device for public places. Background Technology

[0002] Fire safety is of paramount importance in public places such as shopping malls, hotels, and office buildings. Once a fire occurs, the smoke produced will not only threaten people's lives but also damage the equipment and structure inside the building. Therefore, fire exhaust systems have become an indispensable part of public places. However, traditional fire exhaust systems often only focus on the emission of smoke while neglecting the filtration and purification of smoke, resulting in the emission of smoke still containing a large number of harmful substances and causing secondary pollution to the environment.

[0003] According to the information obtained from the authorization announcement number "CN222854954U", a fire smoke exhaust filtration device for public places is described. The device's primary filtration component uses a ring-shaped filter to initially filter the smoke and remove large particulate impurities. The secondary filtration component then uses activated carbon inside the first and second sleeves to further adsorb and filter the smoke, effectively removing harmful substances from the smoke and ensuring the purification effect of the smoke.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the existing technology: when a fire occurs in a public place, the smoke contains a large amount of dust. Although the above-mentioned reference cases can purify the harmful substances in the smoke, the effect on the dust in the smoke is poor.

[0006] Furthermore, because the dust in the smoke from a fire can absorb toxic gases and chemicals such as carbon monoxide, sulfur dioxide, and nitrogen oxides, it is very easy for people to inhale it when escaping from a fire. This can cause poisoning symptoms such as headache, dizziness, nausea, vomiting, and difficulty breathing, and in severe cases, it can even lead to coma and death. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The filtration mechanism of this utility model can effectively treat the smoke generated by fires in public places. The smoke is introduced into the box through the air intake fan in the air intake duct. The conical filter in the filter element can initially filter large dust and impurities in the smoke. Then, the air pump draws air from the inside of the water tank, creating a negative pressure inside the water tank. This negative pressure in the water tank is then used to draw air from the top of the inner cavity of the box through the vertical pipe connected to the air intake hood. The smoke is further filtered by the water in the water tank, effectively removing dust from the smoke. This makes up for the shortcomings of the existing technology in terms of poor dust treatment, greatly reducing the content of dust and harmful substances in the emitted smoke, reducing secondary pollution to the environment, and also reducing the risk of human inhalation of toxic and harmful substances.

[0023] 2. The cleaning mechanism in this utility model can clean the filter elements and ensure the continuity of the filtration effect. The motor drives the turntable to rotate, and the turntable drives the conical filter cylinder to swing through the swing rod. With the cooperation of the elastic telescopic rod and the fixed plate, the conical filter cylinder swings stably. The dust and other impurities filtered on the conical filter cylinder fall into the collection shell during the swing and enter the dust collection box through the sewage pipe. This realizes the automatic cleaning of the filter components, avoids filter screen clogging affecting filtration efficiency, extends the service life of the device, and reduces manual maintenance costs.
