Thermostatic liquid gasification jet spray gun system and its gasification and jetting method

Abstract

The invention relates to a constant-temperature liquid gasification air ejection spray gun system which comprises a liquid storage and pumping system, a compressed air pumping system, a double-fluid atomization spray gun, a combustor, a combustion boiler, a dust flue or container, a dust collector and an exhaust fan. The system is characterized in that the double-fluid atomization spray gun is changed into a constant-temperature liquid gasification air ejection spray gun with gasification air ejection, the constant-temperature liquid gasification air ejection spray gun comprises a constant-temperature spray gun and an evaporator, a liquid which is cooled by the constant-temperature spray gun and passes through an ejection tube flows to the evaporator through a pipeline after the temperature is increased to a certain extent, and is heated and evaporated rapidly in a high-temperature environment outside the evaporator, a vapor flow generated after evaporation flows into an ejection tubeof the constant-temperature spray gun and is ejected out from an ejection tube seam, then ejected air of the spray gun in (the combustor, the combustion boiler and the dust flue or container) has functions of (generating heat through combustion, achieving desulfurization and denitrification by being mixed with system air flows, and achieving dust collection by being mixed with system dust-containing air flows) respectively, and the operation cost and the like can be effectively reduced.

AI Technical Summary

Problems solved by technology

Due to the degree of atomization of (fuel type combustion spray gun, dust removal type spray gun, desulfurization and denitrification type environmental protection spray gun), it is determined by (combustion efficiency of fuel oil type combustion spray gun, dust removal efficiency of dust removal type spray gun, desulfurization and denitrification efficiency of desulfurization and denitrification type environmental protection spray gun) ), in fact, the above-mentioned types of dual-fluid spray guns have their optimal value and limit value of liquid-gas ratio. When the liquid-gas ratio is at the optimal value, the atomization effect is the best and the efficiency is the highest. Due to changes in production volume, temperature, gas volume, dust concentration and other factors, it is necessary to increase or decrease the amount of liquid. After increasing or decreasing the amount of liquid, the atomization effect of the spray gun will deviate from the optimal value or even exceed the limit value, which will cause atomization. Poor effect, low efficiency, increased liquid consumption, high operating costs

Since the working environment temperature of the fuel-burning spray gun and the desulfurization and denitrification environmental protection spray gun is basically above 800 degrees, there are general problems of high-temperature oxidation and burning of the spray gun tube or spray gun head, and the service life of the spray gun is reduced.

Due to the poor atomization effect of the dust removal spray gun, droplets are generated, and there is a problem that the wet bottom of the system pipeline equipment is blocked and the normal operation of the equipment is affected.
