The way of traditional back-fire relief heat sink many employings Water spray, it is desirable to operating rate is low, device bulky, inefficiency；In terms of cooling and solution greenhouse gas emission, effect is undesirable；Gas attack after process is strong, and secondary pollution is serious.
Summary of the invention:
It is an object of the invention to provide a kind of waste gas trapping back-fire relief heat sink.
Above-mentioned purpose is realized by following technical scheme:
A kind of waste gas trapping back-fire relief heat sink, its composition includes: casing, described box house is provided with metal gauze demister, bottom described box house, there is alkaline detergent solution, air inlet, gas outlet is had on described casing, on described casing, high pressure positive blower is installed, described high pressure positive blower side, bottom surface have through hole, described air inlet is connected with high pressure positive blower bottom surface port, described gas outlet is connected with outlet pipe, described high pressure positive blower side through hole is connected with admission line, and described backblast pipe is immersed in alkaline detergent solution.
Waste gas trapping back-fire relief cool-down method, the Negotiation speed of waste gas is less than 3m/s, and waste gas sends into casing at air inlet through high pressure positive blower, and the pressure of high-pressure blast is 2000pa to 3000pa, and the flow of high pressure positive blower is 2000m3/h.Gas settles through air inlet pipeline, the area 0.4m of air inlet pipeline2Above, a length of more than 600mm, the degree of depth entering liquid is more than 50mm.Entering into alkaline detergent solution through air inlet pipeline effluent air, eliminate harmful gas therein, the composition of described alkaline detergent solution is based on sodium hydroxide, and the ph value of alkaline detergent solution is 7.5.Described gas carries out the process of water smoke through tinsel except mist net, and described tinsel is 50mm except the thickness of mist net, and installation interval is 50mm, most preferably 4 layers, and initial resistance is 50pa.
Waste gas trapping back-fire relief cool-down method, during work, waste gas enters the temperature of blower fan less than 80 degrees Celsius, the orifice diameter entering water diverter is 1mm, gas flow rate through demister is less than 3m/s, the blower fan of back-fire relief heat sink is equipped with and should ensure that work wind speed is less than 3m/s, solves resistance 2000pa, including the leading portion resistance of ducting.
Beneficial effect:
1. the present invention utilizes high pressure positive blower will thoroughly to block flame transmission in other introducing alkaline detergent solutions of thermal-flame, EGT is down to the temperature levels of cleaning mixture simultaneously, outlet temperature is less than 45 degrees Celsius, pro-alkaline oxide in scavenging and dust granules, through the process of multilamellar demister, the humidity of exit gas is less than 85%.
2. the present invention can quickly block flame propagation, good cooling effect, and Outlet Gas Temperature is close to wash temperature, and carbon dioxide absorption rate, more than 95%, reduces greenhouse gas emission effective, and discharging gas does not has secondary pollution.
Accompanying drawing 1 is the structural representation of the present invention.
