Dry powder extinguishment explosion suppression system of oil tank truck

Abstract

The invention belongs to the technical field of extinguishment explosion suppression of an oil tank truck and discloses a dry powder extinguishment explosion suppression system of the oil tank truck. The system comprises a powder storage box with a spraying hole on an oil tank, a control box, a fire detector, a high pressure gas bomb and a bottle head valve arranged on the high pressure gas bomb, the fire detector is electrically connected with the control box, the control box is electrically connected with the bottle head valve, an outlet of the bottle head valve is connected with a main air tube, the other end of the main air tube is connected with a first branch tube, the other end of the first branch tube stretches into the powder storage box, and the first branch tube stretches into an end socket of the powder storage box to be fixedly connected with a blowing powder mixing tube. The dry powder extinguishment explosion suppression system can effectively restrain detonation or explosion caused by accidents of the oil tank truck, is high in extinguishment speed and simple in equipment operation and has performance of installing a structure which has no influences on the oil tank truck. In addition, a reducing valve sends pressure gas in an oil tank to enable the pressure gas, and a user can safely overhaul the oil tank after certain concentration is achieved.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing and explosion suppression for oil tank trucks, and more specifically relates to a dry powder fire extinguishing and explosion suppression system for oil tank trucks. Background technique [0002] Explosions caused by accidents such as open flames, static electricity, welding, gunshots and collisions occurred one after another during the transportation or maintenance of oil tank trucks, which not only caused a devastating disaster to the lives of drivers and maintenance personnel and the safety of oil tank trucks, but also caused great harm to the surrounding people. and property causing great harm. Especially in recent years on the expressway because of the oil tank truck leaking and catching fire caused by the rear-end collision, the accidents that caused the explosion of the oil tank truck occurred from time to time because the vehicle itself lacked feasible fire extinguishing and res...
