Method for preventing high-temperature two-explosion of gas high-energy impulse dusting device

Abstract

A method for preventing high temperature two responses of fuel high energy pulse dust remove device. The fuel high energy pulse dust remove device is composed of a mixture tank, a backfire preventing tank, an ignition tank, a pulse tank and a pulse nozzle. The device is characterized in that: a wind curtain is formed between the pulse tank and the pulse nozzle, the said has certain wind pressure. The wind curtain which has certain wind pressure can be used to block mixture gas, improve mixture gas pressure and fullness in the ignition tank and the pulse tank, and block the direction contact of the mixture gas in the high temperature smoke and dust remove device. The method and device provided in the present invention can effectively block the direction contact of the mixture gas in the high temperature smoke and dust remove device, reduce the bad disturb to the work of the dust remove device from the high temperature smoke.

Description

technical field [0001] The invention relates to a boiler ash removal device, in particular to a method and an air curtain device for preventing the gas high-energy pulse ash removal device from high temperature secondary noise. Background technique [0002] The flue gas generated by the combustion of fuel in the heating boiler is attached to the heating surface of the boiler, which will increase the thermal resistance and reduce the heat exchange efficiency. The thermal conductivity of ash is 0.058~0.165W / (m 2 ℃), which is only 0.5% of the steel plate. If the heating area of ​​the boiler is ash and coke during operation, the thermal resistance will increase, the heat transfer will be weakened, the exhaust gas temperature will increase, and the heat loss will increase (the ash thickness is 1mm, and the heat loss will increase by about 4%. ), the efficiency of the heating furnace or boiler is reduced; the accumulation of dust can easily cause local overheating of the metal tu...

AI Technical Summary

Problems solved by technology

[0004] The temperature of the heating surface area where the soot is blown by the gas-fired high-energy pulse ash removal device is relatively high, and the temperature of the high temperature area is 700-1200°C. Due to the direct contact and radiation of the high-temperature flue gas to the mixed gas, the ash removal device is ignited in advance, and 2 beeps occur. The phenomenon

The working energy is reduced, and the good effect of ash removal cannot be achieved
