Abstract
The invention discloses a gas-direct-contact-type ice slurry generator. The generator comprises a concentric annular spray-nozzle, a de-icer, a stirrer, a drive shaft, an ice outlet, and a driving motor. The concentric annular spray-nozzle is arranged at the lower end of a generator body. The drive shaft is arranged at the center of the generator body. The stirrer is arranged on the drive shaft. The driving motor is arranged above the generator body. The ice outlet is provided on the side wall on the upper part of the generator body. The upper end of the drive shaft is connected with the driving motor. The lower end of the drive shaft is connected with the de-icer. The de-icer comprises a support and de-icing blades. The de-icing blades are vertically arranged on the lower surface of the support. The support is provided with 1-3 arms. The lower ends of the de-icing blades extend into annular flow channels of the concentric annular spray-nozzle. The number of the de-icing blades on a single support arm is the same with that of the annular flow channels of the concentric annular spray-nozzle. An ice-making solution is provided in the generator body. With the generator provided by the invention, ice blockage can be effectively prevented, and system ice-making solution leakage can be reduced. The ice slurry is stirred, such that a heat exchange effect is reinforced. Therefore, the stable and highly efficient operation of the ice slurry preparation system is promoted.
Description
Technical field
The present invention relates to energy field of air conditioning, relate in particular to a kind of gas direct contact type ice slurry maker.
Background technology
Gas contact method ice slurry preparation system [patent No. ZL 2,009 1 0102116.5] is using the environmental friendliness such as air, nitrogen working medium as refrigerating medium and ice making solution direct contact heat transfer preparing ice slurry.Adopt gas as refrigerating medium can reduction system investment and maintenance cost, avoided liquid refrigerating medium to dissolve in ice making solution causing the problem of cold-storage liquid contamination simultaneously.
But aforementioned ice slurry preparation system exists following problem: 1. it is serious that ice generator nozzle ice making solution is crossed cold rear ice crystal gathering, ice very easily occurs stifled, affects system stable operation; 2., when ice generator ice content (IPF) raises, the heat convection effect of refrigerating gas and ice making solution weakens, and affects system heat exchange efficiency; 3. system operation phase ice making solution leaks in a large number from nozzle, and maintenance cost improves.Therefore, considering to add in ice generator inside dynamic rotary parts to realize the stifled effect of anti-stagnant ice and ice slurry transports.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of gas direct contact type ice slurry maker is provided.
Gas direct contact type ice slurry maker comprises concentric ring shower nozzle, ice removal, agitator, power transmission shaft, ice mouth, drive motors, maker body lower end is provided with concentric ring shower nozzle, maker body center is provided with power transmission shaft, power transmission shaft is provided with agitator, maker body top is provided with drive motors, maker body upper portion side wall is provided with ice mouth, power transmission shaft upper end is connected with drive motors, power transmission shaft lower end is connected with ice removal, ice removal comprises support and ice removing blade, support lower surface is vertically provided with ice removing blade, support is provided with 1～3 arm, the annular channel of concentric ring shower nozzle is stretched in ice removing blade lower end, the ice removing blade quantity of support single armed is identical with the annular channel number of concentric ring shower nozzle, in maker body, fill ice making solution.
The beneficial effect that the present invention has compared with existing common ice generator is:
1) adopt the structure of rotating blade, by mechanical means, prevent that ice making solution from crossing cold formation ice crystal at nozzle and assembling, effectively solved the stifled problem of ice.Therefore ice making solution does not need to add any antifreezing agent (water), saves the cost of investment of system; In addition refrigerating gas require temperature range more extensive, be convenient to the low-temperature receiver of the coupling of ice slurry preparation system from now on liquefied natural gas (LNG) temperature range.
2) utilize liquid flooding principle, adopt long and narrow concentric ring runner as spout, in the time that air velocity reaches a certain critical value, ice making solution will can not leak downwards by spout; At concentric ring runner refrigerating gas access place assembling stop valve, by greatly reducing ice making solution and open, stop in system the leakage in stage, reduce ice-making system maintenance cost.
3) when in ice generator, ice content (IPF) raises, in ice making solution, refrigerating gas motion resistance increases, weaken with ice making solution heat convection effect, adopt agitator structure to increase flowing that in ice making solution, ice is starched, and the ice slurry of generation is transported to beyond ice generator in time, control ice content, can effectively strengthen heat transfer effect.

Detailed description of the invention
As shown in the figure, gas direct contact type ice slurry maker comprises concentric ring shower nozzle 1, ice removal 2, agitator 3, power transmission shaft 4, ice mouth 5, drive motors 6, maker body lower end is provided with concentric ring shower nozzle 1, maker body center is provided with power transmission shaft 4, power transmission shaft 4 is provided with agitator 3, maker body top is provided with drive motors 6, maker body upper portion side wall is provided with ice mouth 5, power transmission shaft 4 upper ends are connected with drive motors 6, power transmission shaft 4 lower ends are connected with ice removal 2, ice removal 2 comprises support 7 and ice removing blade 8, support 7 lower surfaces are vertically provided with ice removing blade 8, support 7 is provided with 1～3 arm, the annular channel of concentric ring shower nozzle 1 is stretched in ice removing blade 8 lower ends, ice removing blade 8 quantity of support 7 single armeds are identical with the annular channel number of concentric ring shower nozzle 1, in maker body, fill ice making solution.
Operation principle of the present invention is: refrigerating gas passes into ice generator inside and ice making solution generation heat exchange by concentric ring shower nozzle 1.According to liquid flooding principle, in the time that air velocity is enough large, ice making solution will can not leak downwards by shower nozzle.Ice removing blade 2 is insinuated among annular channel, drive motors 6 driven rotary that connected by power transmission shaft 4, and the ice crystal that can stop ice making solution to cross cold rear formation is assembled at spout position, has prevented the generation that ice is stifled.Agitator 3 is connected with drive motors 6 by power transmission shaft 4, by drive motors 6 driven rotary, the ice slurry generating is discharged outside ice generator in time by ice mouth 5, ice content (IPF) in maintenance ice generator is at ideal range, keep inner ice making solution and ice to starch in flow regime simultaneously, be conducive to maintain the heat convection effect of refrigerating gas and ice making solution.
