Cleaning-free flame arrester

Abstract

The invention discloses a cleaning-free flame arrester and relates to the technical field of flame arresters. The cleaning-free flame arrester comprises a left shell and a right shell, wherein the sides, opposite to each other, of the right shell and the left shell are fixedly connected through a first bolt; first flame retardant cores are movably connected with the opposite sides of the left shell and the right shell; and sealing gaskets are movably connected between the two first flame retardant cores and the left shell as well as between the two first flame retardant cores and the right shell. According to the cleaning-free flame arrester, second flame retardant cores and the first flame retardant cores rotate relative to each other, impurities such as greasy dirt blocked in the middleof meshes can be separated from the meshes, the impurities can be blown away from the meshes by using high-pressure gas, the anti-blocking effect is better, the flame arrester does not need to be manually disassembled for cleaning, the labor intensity of workers is greatly reduced, the cleaned impurities can be directly discharged out of the shells through a sewage discharge pipe, the operation isconvenient, and the sealing gaskets and sealing rings jointly act, so that the sealing effect of the flame arrester can be improved, gas leakage is prevented, and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of flame arresters, in particular to a no-cleaning flame arrester. Background technique [0002] The flame arrester is a safety device used to prevent the spread of flames of flammable gases and flammable liquid vapors. It is generally installed in pipelines conveying flammable gases, or on ventilated tanks to prevent the passage of flames (deflagration or detonation) , consisting of a flame arrester core, a flame arrester shell and accessories. Flame arresters are also commonly used on pipelines transporting flammable gases. If the flammable gas is ignited, the gas flame will spread to the entire pipe network. In order to prevent this dangerous In case of accident, a flame arrester should also be used. The flame arrester can also be used on the pipeline with open flame equipment to prevent backfire accidents, but it cannot prevent the open flame combustion of flammable gases and liquids that are burning ope...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a no-cleaning flame arrester, which solves the problem that the small through-holes on the internal fire arresting element are easily blocked by soot and impurities carried in the flame, and need to be dismantled and washed frequently for cleaning, greatly Increase the labor intensity of workers and reduce the problem of practicality
