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 produced the ice slurry with environmental friendliness working medium such as air, nitrogen as refrigerating medium and the direct contact heat-exchanging of ice making solution.Adopt gas can the reduction system to invest and maintenance cost, avoided liquid refrigerating medium to dissolve in the problem that ice making solution causes the cold-storage liquid contamination simultaneously as refrigerating medium.
But aforementioned ice slurry preparation system exists following problem: 1. it is serious that ice making solution in ice generator spout place is crossed the ice crystal gathering of cold back, and it is stifled that ice very easily takes place, and influences system stable operation; 2. when ice generator ice content (IPF) raise, the heat convection effect of carrying cold air and ice making solution weakened, and influences system's heat exchange efficiency; 3. system's operation phase ice making solution leaks from spout in a large number, and maintenance cost improves.Therefore, consider to transport at the inner anti-stagnant ice of dynamic rotary part realization stifled effect and the ice slurry of adding of ice generator.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of gas direct contact type ice slurry maker is provided.
The 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 the concentric ring shower nozzle, and maker body center is provided with power transmission shaft, and power transmission shaft is provided with agitator; Maker body top is provided with drive motors, and maker body upper portion side wall is provided with ice mouth, and the power transmission shaft upper end links to each other with drive motors; The power transmission shaft lower end links to each other with ice removal, and ice removal comprises support and remove ice blade that the support lower surface vertically is provided with except that ice blade; Support is provided with 1～3 arm; Remove the annular channel that the concentric ring shower nozzle is stretched in the ice blade lower end, the deicing knife number of support single armed is identical with the annular channel number of concentric ring shower nozzle, fills ice making solution in the maker body.
The present invention compares the beneficial effect that has with existing common ice generator:
1) adopts the structure of rotating blade,, prevent that ice making solution from crossing cold formation ice crystal and assembling at the spout place, solved the stifled problem of ice effectively through mechanical means.Therefore ice making solution need not add any antifreezing agent (water gets final product), practices thrift the cost of investment of system; What carry cold air in addition requires temperature range more extensive, is convenient to the low-temperature receiver of ice slurry preparation system coupling liquefied natural gas (LNG) temperature range from now on.
2) utilize the liquid flooding principle, adopt long and narrow concentric ring runner as spout, ice making solution will can not leak downwards through spout when air velocity reaches a certain critical value; Carry cold air porch assembling stop valve at the concentric ring runner,, reduced the ice-making system maintenance cost greatly reducing ice making solution opened, stops the stage in system leakage.
When 3) ice content (IPF) raises in the ice generator; Carrying the cold air resistance of motion in the ice making solution increases; Weaken with ice making solution heat convection effect, adopt agitator structure to increase flowing that ice is starched in the ice making solution, and the ice that will generate slurry in time is transported to beyond the ice generator; The control ice content can effectively strengthen the heat exchange effect.

The specific embodiment
As shown in the figure, the 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, and maker body center is provided with power transmission shaft 4, and power transmission shaft 4 is provided with agitator 3; Maker body top is provided with drive motors 6, and maker body upper portion side wall is provided with ice mouth 5, and power transmission shaft 4 upper ends link to each other with drive motors 6; Power transmission shaft 4 lower ends link to each other with ice removal 2, and ice removal 2 comprises support 7 and remove ice blade 8 that support 7 lower surfaces vertically are provided with except that ice blade 8; Support 7 is provided with 1～3 arm; Remove the annular channel that concentric ring shower nozzle 1 is stretched in ice blade 8 lower ends, support 7 single armeds to remove ice blade 8 quantity identical with the annular channel number of concentric ring shower nozzle 1, fill ice making solution in the maker body.
Operation principle of the present invention is: carry cold air and feed the inner and ice making solution generation heat exchange of ice generator through concentric ring shower nozzle 1.According to the liquid flooding principle, when air velocity is enough big, ice making solution will can not leak downwards through shower nozzle.Remove ice blade 2 and be insinuated among the annular channel,, can stop ice making solution to cross ice crystal gathering that cold back forms, prevented the stifled generation of ice at the spout position by drive motors 6 driven rotary that power transmission shaft 4 connects.Agitator 3 links to each other with drive motors 6 through power transmission shaft 4; By drive motors 6 driven rotary; In time discharge ice generator outside through ice mouth 5 the ice slurry that generates; Ice content (IPF) in the maintenance ice generator keeps inner ice making solution and ice slurry to be in flow regime at ideal range simultaneously, helps keeping the heat convection effect of carrying cold air and ice making solution.
