Flare backfire prevention device for thermal power plant

Abstract

The invention discloses a torch backfire-prevention device for a thermal power plant. The torch backfire-prevention device is characterized in that a fire eruption port is formed in the center of theupper surface of a top cover, a main body is mounted at the position, close to the bottom end, of the inner wall of the top cover in a threaded mode and internally provided with a water storage tank,four water pumping pipelines are inlaid in the positions, close to the bottom end at the periphery of the water storage tank, of the main body, an annular water storage channel is formed in the position, close to the middle, of the periphery of the main body, the other ends of the water pumping pipelines penetrate through the main body to mutually communicate with the water storage channel, a water pump is mounted at the bottom end in the water storage tank through bolts, and four water pumping pipelines are mounted at the output end of the water pump in a threaded mode. Through the arranged structures such as the water storage tank and the water storage channel, the torch backfire-prevention device is overall subjected to water sealing conveniently when used, effective cooling is conducted, and thus the situation of high-temperature backfire is prevented; and through cooperation with the structures of a hydraulic pump and the like, the airtightness of the torch backfire-prevention device is enhanced in use, and the situations of leakage and the like of the torch backfire-prevention device are prevented.

Description

technical field [0001] The invention relates to the technical field of backfire prevention, in particular to an anti-backfire device for a torch used in a thermal power plant. Background technique [0002] A thermal power plant, referred to as a thermal power plant, is a factory that uses combustibles (such as coal) as fuel to produce electrical energy. Its basic production process is: when the fuel is burned, the water is heated to generate steam, the chemical energy of the fuel is converted into thermal energy, the steam pressure drives the steam turbine to rotate, the thermal energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy. The prime mover is usually a steam engine or a gas turbine, and in some smaller plants, an internal combustion engine may also be used. They all generate electricity by using the pressure drop in the process of turning high-temperature, high-...

AI Technical Summary

Problems solved by technology

[0004] 1. The anti-tempering equipment of the torch in the prior art generally adopts two or more one-way valves to combine, but when such a structure is used, its anti-tempering structure cannot reach the anti-tempering structure, so it cannot Meet the needs of existing technology

[0005] 2. The torch in the prior art has a simple structure and poor sealing performance when it is installed with its top cover, so it cannot meet the needs of the prior art
