Subway fire emergency rescue co purification vehicle

Abstract

The invention discloses an emergency rescue carbonic oxide (CO) purifying vehicle for subway fire. The emergency rescue CO purifying vehicle for subway fire comprises a controlling chamber, a power chamber, a cooling chamber and a reaction chamber. The controlling chamber is connected with the power chamber end to end. The cooling chamber is connected with the reaction chamber end to end and communicated with the reaction chamber through a pipeline with a fan. A contractive flexible pipe which is communicated into the cooling chamber and contracts outwards is arranged outside the cooling chamber. The contractive flexible pipe is provided with a fan. CO absorption liquid is contained in the reaction chamber. With the technical scheme, by means of a power traction system, the emergency rescue CO purifying vehicle can automatically travel to a fire spot, uses the fan to convey toxic smoke into the cooling chamber for cooling. The cooled smoke is communicated into the reaction chamber to undergo CO absorption and exhausted into a subway system after being purified. The emergency rescue CO purifying vehicle for subway fire is simple in structure, convenient to operate, capable of benefiting production and use and convenient to popularize widely.

Description

technical field [0001] The invention relates to a subway fire emergency rescue device, especially suitable for an emergency rescue CO purification vehicle for eliminating CO poisonous smoke when the CO concentration in a subway fire is high. Background technique [0002] With the rapid development of subways, subway fires have attracted more and more attention. Since the 1990s, many major subway fires have occurred around the world. In my country alone, there have been 3 major fires and 1 extremely large fire. Subway fires are often accompanied by heavy casualties and huge property losses, and the social impact is extremely bad. After investigation and research, it is found that more than 80% of the casualties in subway fires are caused by carbon monoxide poisoning, but the current common method to eliminate carbon monoxide in subway fires is to rely on the smoke exhaust system. Once the smoke exhaust system fails, the consequences will be more serious. External rescue is ...

AI Technical Summary

Problems solved by technology

The common method of external emergency rescue is to use fans to exhaust and supply air from the ground. The pipeline is long and the effect is poor. Therefore, it is urgent to find a quick and effective method to eliminate carbon monoxide in subway fires.
