Detailed description of the invention
Fig. 1 is the structural schematic diagram of this technology system flow.
Fig. 2 is the structural schematic diagram of this technology spray gun.
Specific embodiment
As shown in Fig. 1 Fig. 2: a kind of equipment reducing nitrous oxides concentration in glass furnace fume discharge, including pressure pan
1, the input terminal of the pressure pan 1 is connected with urea solution output end, and the urea solution output end is by being pumped, institute
1 top of pressure pan stated is equipped with the air pressurization device 2 for air pressurized, and air pressurization device 2 passes through compressed air hose
Road 3 connects pressure pan 1, and 1 output end of pressure pan connects spray gun 6 by urea water lines 5.
There are 2-3 stainless steel, high voltage bearing tank body respectively；2 stainless steel sector spray guns 6；Delivery system；Ratio by weight
The urea water liquid of preparation.
There are liquid feed valve, intake valve, exhaust valve, explosion-proof valve, tapping valve, liquid valve above stainless steel, high voltage bearing tank body.
The working principle of this technology are as follows:
It is 1050 DEG C in temperature, NO is restored as reducing agent using ureaXIt reacts as follows:
CO(NH2)2+NOX+1/2O2→2N2+CO2+H2O
Running the energy used is pressure-air, and pressure is not less than 0.4MPa.
There are liquid feed valve, intake valve, exhaust valve, explosion-proof valve, tapping valve, liquid valve above stainless steel, high voltage bearing tank body；
Stainless steel gun shot, fan-shaped lance head；
Pipeline system；
Spray gun 6 is mounted on the specific position of flue；
The urea water liquid of ratio preparation by weight.
Double pressure pans carry out single tank operation in fluid infusion, can mutually switch, not deactivate in operation.
By taking 2 pressure pan parallel-connection structures as an example, solid urea and water are melting into urine according to certain weight proportion first
After plain liquid, it is transported to pressure pan 1 using pump, pressure-air pressurization is then carried out and is transported to after pressure meets by transportation system
At spray gun 6, after being atomized finally by spray gun 6, at urea liquid spirt flue specific temperature.Reaching reduces nitrogen oxidation in flue gas
Object concentration meets environment protection emission requirement.
