Cooling and oil evacuation firefighting unit for fire extinguishing with liquid oil tank

Abstract

The invention relates to a cooling and oil evacuation firefighting unit for fire extinguishing with a liquid oil tank, comprising a casing, wherein, the casing is a relative obturator, the panels of the casing are heat exchange trough plates, an oil collecting tank is arranged in the inner side of the right side plate, an openmouthed bend is arranged in the tank and connected with the pipeline ofan oil evacuation system; the left and right side plate of the casing are respectively provided with at least one water inlet and one water outlet, and the water inlet is connected with a water injection system; the casing is provided with a bearing pillar, and the bearing pillar is arranged between a heat exchange trough plate and a base plate; cooling water flows in the casing, inflammable oil is convectively cooled by cooling water on the heat exchange trough plate and is collected in a sealed accident oil storage pool. According to the invention, the problem that flow fire in the storage tank area is difficult to control is effectively solved, and by delivering the inflammable oil to the area far away from the tank, the heat harm of fire hazard on the tank can be reduced effectively.

Description

technical field [0001] The invention belongs to the field of fire safety facilities. Specifically, the utility model relates to the fire-fighting cooling and fire extinguishing of the flowing fire caused by the leakage of the tank body of the flammable liquid storage tank and the collection device of the leaked flammable liquid. Background technique [0002] With the development of the economy, a large number of petrochemical and other flammable liquid storage tank areas have emerged, which has brought new challenges to fire protection. A large amount of flammable liquid in the storage tank is easy to catch fire when it encounters a fire source. Once a leak occurs, it will cause a large area of ​​flowing fire, aggravate the spread of the fire, cause greater thermal damage to the tank wall, and may even cause the tank wall to fail due to high temperature. Especially for liquids with high vapor pressure, during the development of flowing fire, the steam pressure will increase...

AI Technical Summary

Problems solved by technology

[0009] In order to overcome the deficiency that the existing fire-fighting devices for storage tank farms cannot effectively restrain the early development of the flowing fire, and the existing fireproof grille cannot solve the problem of the cooling and extinguishing of the flowing fire under the grille, the present invention provides an easy-to-install , low cost, good cooling effect, can effectively extinguish the flowing fire cooling and oil discharge fire fighting device
