Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a foam fire extinguishing device in a coking oil depot area. Background Art

[0002] The coking plant is a chemical industrial enterprise that produces hazardous chemicals. Its production process involves a large amount of hazardous substances such as crude benzene, coke oven gas, coal tar, washing oil, sodium hydroxide, sulfuric acid and other chemical raw materials. Therefore, once an accident occurs, the consequences will be disastrous. In the on-site disposal of the oil depot area, in order to effectively prevent and curb the occurrence of accidents, it is necessary to install supporting fire protection measures in advance to improve the disposal capacity and ability to respond to accidents in the oil depot area of ​​the coking plant.

[0003] Existing fire-fighting measures cannot respond quickly to fires if they rely solely on fire trucks. Therefore, supporting fire-fighting equipment is often installed in oil depot areas to quickly deal with sudden fires.

[0004] When the existing fire extinguishing device is performing fire extinguishing work, it is necessary to manually pull the fire water pipe and the outside foam truck to reach the vicinity of the fire source to perform foam and spray fire extinguishing work. The foam truck will still consume unnecessary time when it arrives at the connection or in the process of arranging the pipe, and it is easy to miss the best time for fire extinguishing. At the same time, oil tanks as containers of flammable materials should be protected, so as to reduce the probability of major fires. For this reason, we propose a foam fire extinguishing device for coking oil depot area. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a foam fire extinguishing device for a coking oil depot area.
