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
Affiliated technical field
The present invention be specifically related to petrochemical enterprise to crude oil and product oil carry at reactor production and processing, pipeline, oil storage tank stores, safe fire prevention field in the oil truck transportation.
Background technology
Known to the inventor, the crude oil products of petrochemical enterprise all is inflammable, explosive, corrosion-prone materials both at home and abroad at present, the production process majority be at high temperature, high pressure, at a high speed, finish by transporting of chemical reaction and material under the rigor condition such as toxicity, corrosion, the technological operation continuity is strong, form explosive mixture in process pipelines and the reactor easily, and the burning things which may cause a fire disaster place of the igniting in the Production Regional is more, have great fire and explosion hazard, production, the equipment characteristic of petrochemical enterprise these self have determined there is distinctive disaster hidden-trouble.In petrochemical industry production, storage and transportation apparatus, it is that relatively effective measures take place in fire preventing that safety devices against fire is set.Safety devices against fire is extensive use of aborning and obtains having of good result: 1. back-fire relief equipment has safe fluid-tight, trapped well, spark arrester, check valve, fire insulation valve etc., and its effect is to prevent that flame from swarming into equipment, pipeline or stoping flame to be expanded betwixt.2. explosion-proof relief equipment has safety valve, rupture disk (burst disk), blow-down pipe etc., is installed on the production equipments such as pressure vessel, pipeline, and its effect has been the step-down explosion-proof.3. spark arrester.Be installed on the equipment and the device that produce Mars, its effect is to prevent the Mars combustible that ignites that flies out.4. autodetector.Be used to detect objects such as combustable gas concentration, temperature, smog, its effect is to report to the police automatically when surpassing certain value (concentration), starts the interlock automatic stopping and starts the self-extinguishing facility.Above-mentioned measure is no doubt important, in case burn, at first closes all valves, implements fire extinguishing; If blast, the state of affairs enlarges, and when the fire fighting difficulty strengthens, employs fire department and puts out a fire, and lacks the method that a kind of effective mitigation of collecting while put out a fire detracts.This method combines in above-mentioned former thereby a kind of prevention and collection method for oil and gas fire disasters is provided exactly.The using of this method makes the water oil pyrogene that goes out be reality.
Summary of the invention
Purpose of the present invention is exactly in order to solve fire and to take place, and avoids the chain reaction of inflammable and explosive substances and blast to burnout and provides a kind of and collect aflame petroleum gas safely and effectively, reduces quantity combusted, prevents the prevention and collection method for oil and gas fire disasters that fire continues to fire.The present invention is achieved in that described a kind of prevention and collection method for oil and gas fire disasters comprises: pipeline valve 1, pipeline heat dissipation type anti-backfire valving 2, oil transfer pump 3, pipeline 4, oil gas jar heat dissipation type anti-backfire valving 5, tank body valve 6, the anti-backfire pressure relief device 7 of can ventilating, tank body 8, pipeline connector 9.It is characterized in that: the anti-backfire pressure release safety device 7 of can ventilating is installed at the top at tank body 8, and the oil inlet and outlet level in tank body 8 bottoms is installed in parallel heat dissipation type anti-backfire valving 5 and tank body valve 6, and connects with petroleum pipeline 4; Petroleum pipeline valve 1 is in parallel with pipeline heat dissipation type anti-backfire valving 2 levels, settles oil transfer pump 3 between two petroleum pipeline valves 1.
Description of drawings
Accompanying drawing is a kind of prevention and collection method for oil and gas fire disasters schematic diagram, pipeline valve 1, pipeline heat dissipation type anti-backfire valving 2, oil transfer pump 3, pipeline 4, oil gas jar heat dissipation type anti-backfire valving 5, tank body valve 6, the anti-backfire pressure relief device 7 of can ventilating, tank body 8, pipeline connector 9 among the figure.
The specific embodiment
Embodiment is described in further details the present invention below in conjunction with accompanying drawing, say that as accompanying drawing a kind of prevention and collection method for oil and gas fire disasters that shows can collect aflame petroleum gas safely and effectively, can prevent that fire from continuing to fire, it is characterized in that: the anti-backfire pressure release safety device 7 of can ventilating is installed at the top at tank body 8, when fire takes place, open the anti-backfire pressure release safety device 7 of to ventilate, to prevent firing and pressure when reducing tank interior and firing of tank interior; The oil inlet and outlet level of tank body 8 bottoms is installed in parallel heat dissipation type anti-backfire valving 5 and tank body valve 6, and connects with petroleum pipeline 4; Petroleum pipeline valve 1 is in parallel with pipeline heat dissipation type anti-backfire valving 2 levels, settles oil transfer pump 3 between two petroleum pipeline valves 1, is transported in safe tank body 8 or the pipeline 4 so that in time collect the petroleum gas of burning in tank body 8 or the pipeline 4; Its method is valve-off 1 and 6, opens heat dissipation type anti-backfire valving 2 and 5, allows petroleum gas carry towards the tank body 8 and pipeline 4 directions of safety; The heat dissipation type anti-backfire valving (2) in the pipeline and the characteristics of (5) are to prevent from also will to reduce when tempering phenomenon from appearring in pipeline the temperature of petroleum gas through herein the time.
