Four-channel distribution and initiation cabinet with function of supplying air for novel protection air curtain

Abstract

The present invention relates to a new four-channel self-supply air supply and gas distribution induction cabinet for a new type of protective air curtain. The acetylene supply main pipe is successively installed with a filter fire arrester and an acetylene valve, and the air supply main pipe is equipped with a filter pressure reducing valve. The air supply branch pipe one is successively installed with an air solenoid valve one and an air one-way valve one, and the acetylene supply branch one is successively installed with an acetylene outlet valve one and an acetylene one-way valve one, and the above-mentioned mixed gas pipe one is Primary mixing check valve 1 is installed, and air solenoid valve 2 and air check valve 2 are successively installed on said air supply branch pipe 2. Acetylene outlet valve 2 and acetylene check valve are successively installed on said acetylene supply branch pipe 2. Two, the first mixing check valve two is installed on the gas mixing pipe two. The invention overcomes the disadvantages of high distributed price and high centralized risk through the setting of the four-channel self-supply air distribution trigger cabinet of the new protective air curtain, increases the reliability, reduces the cost, simplifies the structure, has low failure rate, and is safe. Reliable, energy saving and environmental protection, easy to operate.

Description

technical field [0001] The invention belongs to the field of boiler soot blowers, and in particular relates to a four-channel self-supply air supply and gas distribution trigger cabinet for a novel protective air curtain. Background technique [0002] The soot blowers currently in use often do not have the ability to prevent the impact of chemically corrosive gases on the soot blowing equipment. When the boiler flue gas has serious corrosive gases, these gases will chemically react with the inner wall of the soot blowing equipment, causing corrosion on the inner wall of the equipment, shortening the service life, and affecting the normal use of the equipment. This is mainly reflected in the use of furnaces such as roasting furnaces in metallurgical systems, waste heat furnaces in various chemical companies, and waste incinerators. At the same time, in winter, the hot gas in the flue and the heat dissipation structure of the pulse tank will generate convection between the fl...

AI Technical Summary

Problems solved by technology

At the same time, in winter, due to the hot gas in the flue and the heat dissipation structure of the pulse tank, there will be convection between the flue and the pulse tank, and the water vapor in the flue will be condensed into water, and the water will also corrode the soot blowing equipment.
