The recovery of amount.Because heat collector 8 is arranged at the outside for absorbing spray column 1, so present embodiment is referred to as cooling type embodiment party
Case.
The wet waste gas of heat enters absorption spray column 1 by hot wet exhaust pipe 51 from bottom, with spray dress in absorption spray column 1
The dense hygroscopic solution contact of 2 sprays is put, heat and mass transfer process, release sensible heat and latent heat is carried out and is directly heated hygroscopic solution, carried
The temperature of hygroscopic solution is risen, the low temperature drying waste gas after heat release is flowed out by dry and cold exhaust pipe 56 and absorbs spray column 1.
After the vapor and sensible heat in absorbing hot wet waste gas in spray column 1 is absorbed, concentration reduces to be formed hygroscopic solution
Dilute hygroscopic solution and temperature gets a promotion, dilute hygroscopic solution absorbing the bottom collection of spray column 1, absorb spray column 1 with
Between regenerator 4 under the driving of pressure difference, regenerator 4, the heat release in heat collector 8 of dilute hygroscopic solution are flowed to by weak solution pipeline 76
And heat-carrying agent is heated, and being preheated by dense hygroscopic solution in solution regenerator 6, dilute hygroscopic solution is swollen finally by throttling
Enter regenerator 4 after the reducing pressure by regulating flow of swollen device 9, dilute hygroscopic solution is in regenerator 4 by regeneration coil pipe 5 by boosting it
Indirect steam afterwards carries out heating concentration, produces indirect steam, and the concentration of hygroscopic solution is improved to form dense hygroscopic solution, dense
Hygroscopic solution is driven by solution circulation pump 7, and spray equipment 2, and the heat release in solution regenerator 6 are flowed to by concentrated solution pipeline 71
And dilute hygroscopic solution is preheated, temperature reduction, the dense hygroscopic solution of low temperature is by spray equipment 2 in absorption spray column 1

Explosive evaporation temperature its purpose is to reduce solution in regenerator 4, while the energy resource consumption of vapour compression machine is reduced, because
According to solution and the hot physical property and state rule of water, the pressure of indirect steam is higher, and the sealing property requirement to compressor is higher,
And realize that the energy consumption that identical condensation temperature lifting amplitude is consumed is higher.The pressure of regenerator is less than the pressure for absorbing spray column
Power, this is a significant difference with the absorption total heat recovery system of existing spray column of the invention.
The indirect steam produced in regenerator of the invention 4 is flowed out and in vapour compression machine 10 by indirect steam pipeline 61
Boost in pressure (accordingly the condensation temperature of indirect steam is also significantly enhanced), the secondary steaming after boosting are carried out under effect
Vapour is into exothermic condensation in regeneration coil pipe 5 into liquid, while the weak solution in thermal regeneration device 4 is concentrated through regeneration, it is complete
Indirect steam into condensation heat transfer realizes that pressure separates by steam trap connection 11 and the external world, while by aqueous water discharge system.
The setting of vapour compression machine of the invention 10 realizes boost in pressure and the condensation temperature lifting of indirect steam, so that
So that the temperature of indirect steam is higher than the temperature of solution in regenerator 4, the condensation heat of indirect steam can be used for solution concentration again
Raw heating, realizes recycling for condensation heat and regenerated heat, without additional high temperature thermal source and cooling thermal source, reduces the energy and disappears
