Problems solved by technology

[0003] Boiler explosion soot blowing is a common boiler soot blowing technology. By mixing combustible gas and combustion-supporting gas in a certain proportion, the combustion and explosion of gas is carried out by ignition in the combustion chamber, and the gas shock wave and sound wave generated by the gas explosion are used to affect the boiler. However, the shock wave generated by the explosion will also im

Abstract

The invention discloses a boiler explosion ash blowing technology injecting inert gas for flame retarding. An oxygen gas cylinder, an acetylene gas cylinder, a nitrogen gas cylinder, a Venturi injector, a combustion explosion device, solenoid valves, elbows, tee joints, circular straight pipes, a circular connecting pipe, bolts and nuts are included. An air flow generated by an explosion of oxygenand acetylene in the combustion explosion device is utilized to inject the inert gas, namely nitrogen when reversely passing through the Venturi injector, thus shock of the explosion to a gas delivering pipeline and the solenoid valves is weakened, the nitrogen can block a backfire face generated by the explosion, thus the combustion backfire face is prevented from extending towards the gas cylinders and the solenoid valves, the service life of equipment is prolonged, and the safety of an explosion ash blowing system is improved.

Description

technical field [0001] The invention relates to the field of Venturi technology, in particular to a boiler explosion soot blowing technology for flame-retardant injection of inert gas. Background technique [0002] Venturi involves many fields, including military, energy, agriculture, materials, chemical industry and many other fields. It can generate local low-pressure areas and has high utilization value. The principle of the Venturi tube is that when the fluid flows through the tapered section to the throat, the flow cross section shrinks sharply, the fluid speeds up and the pressure drops, forming a stable low-pressure area, thereby bringing about a low-pressure effect, which has high industrial application value. [0003] Boiler explosion soot blowing is a common boiler soot blowing technology. By mixing combustible gas and combustion-supporting gas in a certain proportion, the combustion and explosion of gas is carried out by ignition in the combustion chamber, and the...
