Prevention and collection method for oil and gas fire disasters

Abstract

The present invention relates to a prevention and collection method for oil and gas fire disasters, which is characterized in that a ventilating anti-backfire decompression safety device 7 is arranged on the top of a tank body 8, the oil inlet port and the oil outlet port at the bottom of the tank body 8 are horizontally equipped with a radiation-type anti-backfire valve gear 5 and a tank body valve 6 in parallel and are connected with an oil pipeline 4 in series; oil delivery pipeline valves 1 are horizontally connected with a pipeline radiation-type anti-backfire valve gear 2 in parallel, and an oil delivery pump 3 is arranged between the two oil delivery pipeline valves 1 so as to collect oil and gas burning in the tank body 8 or the pipeline 4 in time and transmits the oil and gas into the safe tank body 8 or the safe pipeline 4. The method is as follows: closing the valves 1 and 6, and opening the radiation-type anti-backfire valve gears 2 and 5 to delivery the oil and gas towards the direction of the safe tank body 8 and the safe pipeline 4, wherein the radiation-type anti-backfire valve gears 2 and 5 in the pipeline are characterized by preventing backfire phenomenon in the pipeline and simultaneously reducing the temperature when oil and gas passes the valve gears.

Description

Technical field [0001] The invention specifically relates to the technical field of safety and fire protection for petrochemical enterprises in the production and processing of crude oil and refined oil in reactors, pipeline transportation, storage in oil storage tanks, and transportation by tank trucks. Background technique [0002] As far as the inventor knows, the crude oil products of petrochemical enterprises at home and abroad are all flammable, explosive and corrosive substances, and most of the production process is through chemical reaction and It is completed by the transportation of materials, the continuous operation of the process is strong, the explosive mixture is easy to form in the process pipeline and the reactor, and there are many ignition sources in the production area, which has a great risk of fire and explosion. Petrochemical enterprises These own production and equipment characteristics determine the existence of unique fire hazards. In petrochemica...

Problems solved by technology

The above measures are important. Once a fire occurs, first close all valves and put out the fire; if an explosion occurs, the situation expands, and the difficulty of fire fighting increases, the fire department will be used to put out the fire. There is a lack of an effective way to reduce disasters and reduce losses while extinguishing the fire.
