The chilling ring 2 exports to be made up of Quench annular space 16 and spray apertures 14.Quench annular space 16 is the He of chilling ring shell 12
The annulus formed between chilling housing 5.Spray apertures 14 are arranged on Quench shell 12.
Because the presence of Quench annular space 16 so that the liquid of cooled flue gas forms the moisture film uniformly declined in inner walls,
Avoid high-temperature flue gas from directly being contacted with chilling housing 5, be effectively protected chilling housing 5.
Preferably, the injection direction of spray apertures 14 and converging transition center line, i.e., be 75 ° along Fig. 1 vertical direction angles.
From section, as shown in Fig. 2 the annular of the inner cavity chamber 18 and exocoel 17 is circular configuration, and inner cavity chamber
18 and exocoel 17 be concentric structure.
Preferably, the center of circle of the inner cavity chamber 18 and exocoel 17 is arranged on the housing 5 in chilling ring 12, Er Qiezuo
To be preferred, the refrigerant inlet 19 of described inner cavity chamber 18 is arranged at the home position of housing 5.By being arranged such, pass through
Experiment is found, can be greatly reduced the resistance of cooling liquid flowing, be improved the coefficient of heat transfer.
The chilling ring includes inlet 20, and the inlet 20 is arranged on the outside of housing 5.The inlet is circle
On the extended line for the center line that the center of circle of pipe, the inner cavity chamber 18 and exocoel 17 is arranged on pipe.
By being arranged such, it is found through experiments that, relative to other designs, it is possible to reduce the resistance of cooling liquid flowing,
Extend the service life of equipment.
In the outside of rapid-cooling heat exchanger, the shell of described chilling ring includes following four parts：With connecting outside housing 5
Connect, and the Part I 27 to stretch out relative to housing 5, it is then vertical since the end of Part I 27 away from housing 5
The Part II 28 upwardly extended, the Part III 29 to be extended internally then along the end horizontal of Part II 28, it is finally ring
The Part IV 30 of shape structure, the Part IV 30 are internally formed annulus 16 with shell 5.
Preferably, position and the distance in the center of circle that described Part I 27 is connected with housing 5 are greater than the 4th
Divide 30 and the annular spaces 16 that housing 5 is formed and the distance in the center of circle.
One end of the internal partition 13 of described inner cavity chamber 18 is connected to the end of housing 5, and the other end is connected on housing 5.
Ring cavity outlet 15 in being set on internal partition 13.The distance of the interior ring cavity outlet 15 and the one end of internal partition 13 be greater than with it is interior every
The distance of the other end of plate 13.It is positioned close to the opening position of the other end of internal partition 13, the Part IV of described exocoel 17
30 set outer ring cavity outlet 14.
Preferably, the included angle B that described inner cavity chamber outlet 15 is formed with housing 5 is less than exocoel outlet（Spray
Hole 14）The angle formed with housing 5.Pass through above-mentioned setting, it is meant that the outlet of inner cavity chamber is closer to housing 5, it is meant that exocoel
The outlet of room is higher than the outlet of inner cavity chamber.By above-mentioned setting, the space of inner cavity chamber 17 can be caused to become big, buffered from entrance
The impact of 20 fluids entered, reduce the resistance of inner cavity chamber.
Preferably, the extended line of the center line of inner cavity chamber outlet 15 passes through the center of circle.Preferably, the center of spray apertures 14
The extended line of line passes through the center of circle.

R1, the annular radius of exocoel 17 is R2, the outlet of described inner cavity chamber and the line and spray apertures 14 in the center of circle and the line in the center of circle
The angle of formation is C, i.e. the angle that the line of exocoel outlet and the center of circle is formed with housing 5 is B+C.It is found through experiments that, half
Footpath R1 is excessive, and R2 is too small, causes the flow resistance in exocoel 18 too big, and inner cavity chamber's flow resistance is too small, causes fluid to lead to
Cross that spray apertures outwards spray away from too far away, cause heat transfer effect poor, and R1 is too small, R2 is excessive, then can cause inner chamber chamber pressure
Excessive, and exocoel chamber pressure is too small, it is too near to again result in jet length, causes heat transfer effect too poor.For included angle A, together
Sample can not be excessive, if excessive, causes the spray angle of inlet 20 too inclined, cause into inner cavity chamber fluid very little, and
A large amount of fluids can be caused to overstock between the housing 5 and Part I of exocoel 17, add resistance, equally, for included angle B
