A multi-stage stacked variable-diameter split-flow anti-reflash tank device

Abstract

The invention provides a multi-cascade type reducing and shunting anti-backfire tank device which can solve the problem that the conventional anti-backfire tank is poor in backfire prevention effect. The multi-cascade type reducing and shunting anti-backfire tank device comprises a plurality of tank bodies and check valves arranged between every two tank bodies, wherein the tank bodies are filled with water, and more than two partitions which are distributed in a spacing manner are arranged below the water level; a plurality of through holes are formed in each partition; the number of through holes formed in each partition is continuously decreased from bottom to top, but the apertures of the through holes are kept being increased; air outlet ends are arranged at the tops of the tank bodies, and air inlet ends are arranged at the lower parts of the tank bodies; the air outlet ends of the tank bodies positioned at the front ends are connected with the check valves and then are connected to the air inlet ends of the tank bodies positioned at the rear ends; the check valves are opened along the direction from the tank bodies at the front ends to the tank bodies at the rear ends; water feeding ends are further arranged at the tops of the tank bodies, and water drainage ends are arranged at the bottoms of the tank bodies. According to the multi-cascade type reducing and shunting anti-backfire tank device, a multi-cascade type reducing and shunting mode is adopted in each tank body, so that an air duct for backfire is narrowed, and finally the flame can be eliminated; therefore, the extremely good backfire prevention effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of backfire prevention safety devices for flammable gas conveying pipelines, in particular to a multi-stage stacked variable-diameter diversion anti-backfire tank device. Background technique [0002] The anti-tempering tank is a safety device used to prevent the flame at the combustion end from going back to the gas source. The existing tempering tank uses liquid in the tank, and the flammable gas from the gas source enters the combustion end after passing through the liquid. The liquid in the tank Prevent the flame at the combustion end from going back to achieve the purpose of preventing backfire. However, in the actual use process, tempering still occurs from time to time. When the gas is tempered, it is tempered through the center of the gas channel, so the thicker the gas channel, the greater the possibility of gas tempering. Contents of the invention [0003] In order to solve the problems in the p...
