Washing device for heptafluoropropane storage tank and method thereof

Abstract

The invention provides a washing device for a heptafluoropropane storage tank. The washing device comprises a washing bin, a water spraying mechanism, a water supplying mechanism, a temporary storagebin, a gas supplying mechanism, a fixing base and an overturning mechanism, wherein the water spraying mechanism is arranged in the center of the washing bin in a penetrating mode, the temporary storage bin is arranged at the bottom of the water spraying mechanism, hydraulic rods for driving the temporary storage bin to move are fixed to the bottoms of the washing bin through bolts, the water supplying mechanism for supplying water to the water spraying mechanism is arranged on one side of the bottom of the washing bin, and the gas supplying mechanism for supplying gas to the water spraying mechanism is arranged on the other side of the bottom of the washing bin. Compared with the prior art, the washing device for the heptafluoropropane storage tank has the advantages that the interior ofthe heptafluoropropane storage tank is washed through high-pressure water spraying, chippings hung on the wall on the inner wall of the washed storage tank are further cleared through high-pressure gas spraying, and meanwhile, water stains in the inner wall of the storage tank can be rapidly dried through high-pressure gas spraying operation, the washing efficiency of the heptafluoropropane storage tank is improved, and the use effect is better.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a cleaning device and method for a heptafluoropropane storage tank. Background technique [0002] Heptafluoropropane is a clean gas fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects; it is colorless, odorless, low-toxic, non-conductive, non-polluting to protected objects, and will not cause damage to property and precision facilities; it can With a low fire extinguishing concentration, it can reliably extinguish Class B and C fires and electrical fires; the storage space is small, the critical temperature is high, the critical pressure is low, and it can be liquefied and stored at room temperature; after release, it does not contain particles or oily residues, which is harmful to the atmosphere. No damage to the ozone layer (ODP value is zero). [0003] However, when the existing heptafluor...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing heptafluoropropane storage tank cleaning device and its method are in use, the cleaning effect on the inside of the storage tank is not good, and the internal water stains after cleaning remain, the drying is slow, and the use effect is not good.
