Special spray gun for liquid-phase catalyst

Abstract

The invention discloses a special spray gun for a liquid-phase catalyst of ultralow-temperature liquid-phase catalytic reduction method denitration apparatus. The spray gun comprises a spray gun body;the spray gun body comprises a nozzle assembly, a gun rod, a liquid inlet device and an air inlet device; the nozzle assembly, the liquid inlet device and the air inlet device are connected with thegun rod; the liquid inlet device comprises a liquid-phase metal hose, a liquid-phase double-head screw nipple, a liquid-phase threaded check valve and a liquid-phase threaded adjusting ball valve; thegas inlet device comprises a gas-phase metal hose, a gas-phase screw nipple, a gas-phase threaded check valve and a gas-phase threaded ball valve; an adjusting assembly is arranged on the gun rod; the adjusting assembly comprises an adjusting plate, a rotating shaft and a rotating handle; one end of the rotating shaft is connected with the rotating handle; the other end of the rotating shaft penetrates through the gun rod to be connected with the adjusting plate; the adjusting plate is installed inside the gun rod; and the flow of atomized particles can be controlled through the design of theadjusting assembly.

Description

technical field [0001] The invention relates to the technical field of industrial pollution treatment, in particular to a special spray gun for liquid-phase catalysts. Background technique [0002] Flue gas is one of the main emissions of industrial production, which is produced by the combustion of combustibles in burners (ie boilers). Since the flue gas usually contains a large amount of nitrogen oxides such as NOx, if these nitrogen oxides are directly discharged into the atmosphere, it will cause highly corrosive acid rain, so the flue gas must be denitrified (that is, denitrified) before being discharged. . In the existing flue gas NOx treatment technology, the reducing agent containing amino groups is evenly sprayed into the denitration reaction section, and the NOx in the flue gas is selectively reduced to N2 and H2O, so as to achieve the purpose of reducing nitrogen oxides. The denitrification spray gun is the core component of the denitrification equipment. The pe...

AI Technical Summary

Problems solved by technology

The denitrification efficiency of the denitrification spray gun in the prior art is between 30% and 50%. The low denitrification efficiency cannot meet the environmental protection requirements and the use conditions are all under relatively high temperature conditions. The present invention proposes a new solution to the above problems Program
