Formula heat exchanger, the air cooling equipment includes chassis, is set on the chassis and the cooler bin of upper end opening, be set to it is described cold
But several heat-dissipating pipes in case are provided with the air-cooler being connected to inside the cooler bin on the cooler bin.
By using above-mentioned technical proposal, when handling using above-mentioned processing system tail gas, successively by hot exhaust gas
It is passed through in multiple tube bundle heat exchangers, tentatively cooling, condensation is carried out to hot exhaust gas, preliminary tail gas after cooling is passed through air-cooled at this time
In device, while condensed water elimination is to waste water processing station.When tail gas is passed through air cooling equipment, the cold wind pair of air-cooler discharge is utilized
Tail gas is cooled down again, so that the heat of tail gas is further lowered.Finally tail gas is passed through in deodorizing tower, utilizes deodorizing tower
Toxic gas in tail gas is subjected to absorption removing, will finally be used as and help in the exhaust emissions to heating boiler without noxious material
Combustion wind burns.Using there is the exhaust treatment system of high automation, high airtightness to handle tail gas, tail gas is reduced
Discharge, at the same allow tail gas in time and quickly it is processed, reduce the pollution of tail gas, effectively protect environment and
People's health and life, while having achieved the effect that timely processing tail gas.
The further setting of the present invention are as follows: the last one described tube bundle heat exchanger in multiple tube bundle heat exchangers
Interior cooling medium is river water or lake water, and the cooling medium in remaining described tube bundle heat exchanger is fish soup.
By using above-mentioned technical proposal, therefore in fish meal manufacturing process, fish soup can be usually isolated, when the hot tail of fish meal
When gas is discharged, using fish soup as cooling medium, fish soup is heated using hot exhaust gas, improves the viscosity of fish soup,
Good concentrated effect is played, and then improves the quality of fish soup, while the heat in hot exhaust gas is adequately utilized, is reached
The effect of thermal energy recycling and reusing.Tail gas further progress is condensed further through river water or lake water, reduces the heat of tail gas again
Moisture content in amount and tail gas, so that the processing of tail gas is more thorough.And tail gas is carried out using river water or lake water cold
It is solidifying, condensed waste water is directly discharged in the network of waterways or lake, has saved water source, while will not cause to water resource
Pollution.

35, sparge pipe 36 is provided with and communicated between 31 bottom wall of tower body and spray head 35.
After gas is passed through in tower body 31, tail gas successively passes through bamboo-carbon layer 5, poly (sodium aspartate) powder bed 6 and activity
Layer of charcoal 7, so using bamboo-carbon layer 5 and active carbon layer 7 in tail gas water and foul smell adsorb.And make poly- asparagus fern
Propylhomoserin sodium makes-SH ,-NH2 ,=NH in tail gas that polymerization reaction occur, and accelerates the decomposition absorption of pernicious gas.
At the same time, when being passed through tail gas into tower body 31, the pressure of 31 bottom of tower body increases, at this time hydrogen peroxide solution edge
Sparge pipe 36 to 35 direction of spray head flow, finally sprayed by spray head 35, so that adsorption liquid 8 again inhales tail gas
It is attached, the decomposition absorption of pernicious gas is further speeded up, while another step has reached timely processing tail gas and reduced tail gas dirt
The effect of dye.
Working principle: right by multiple tube bundle heat exchangers 11 when handling using above-mentioned processing system tail gas
Hot hot exhaust gas carry out it is tentatively cooling, condense, while by condensed water elimination to waste water processing station.Then former using the heat exchange of cold wind
The heat radiation principle of reason and radiating fin jointly further cools down exhaust gas.Recycle bamboo-carbon layer 5, poly (sodium aspartate)
Powder bed 6 and active carbon layer 7 carry out absorption removing to water and toxic gas, extremely by the exhaust emissions without noxious material finally
It burns in heating boiler as combustion air.
Embodiment 2: a kind of tail gas treatment process of fish meal includes the following steps:
