A heat exchange pore plate is arranged inside the tank body, and the heat exchange pore plate is fixed to the inner wall of the tank body. An external circulation gas return port and an internal circulation liquid return port are formed in the side wall of the gas phase area of the tank body, and an external circulation liquid supply port and an internal circulation liquid outlet are formed in the side wall of the liquid phase area of the tank body. A safety valve is arranged on the top of the tank body. A pressure gage is arranged on the side wall of the gas phase area of the tank body, and a liquidometer is arranged on the side wall of the liquid phase area. Through the arrangement of the tank body, the heat exchange pore plate and the spraying nozzle, oilless operation for long-distance feed liquid of an overlapped low-temperature refrigerating system is achieved, meanwhile, phase change working mediums can be used as refrigerants, the problem that because of adoption of heat conduction oil and other refrigerants, configuration requirements of the system stay high is solved, and system cost is reduced.
Description
Technical field
The present invention relates to art of refrigeration units, specifically a kind of refrigerating circulation vessel.
Background technology
In refrigeration industry, most widely used circulation vessel is the low pressure recycle bucket in ammonia pump liquid provision refrigeration system at present, its function is to guarantee fully to ammonia pump supply low pressure ammoniacal liquor, simultaneously also played ammonia liquor separator, making is gaseous state refrigeration working medium to the diffluence of compressor air suction chamber.
Because said system is directly refrigeration of compressor, so long-range feed flow still needs to consider the problem of oily separation and oil return; And ammonia etc. other be applied to similar barrel pump system working medium its be all subject to the restriction of its freezing point, be only applicable to-50 ℃ and above operating mode.Consider above two kinds of reasons, thus existing low pressure recycle bucket with and the barrel pump refrigeration system that configured be not all suitable for the cascade refrigeration system that evaporating temperature is lower.
Due to technical limitations, present low temperature overlapping project can only adopt direct evaporation measure or traditional refrigerating medium scheme conventionally, but owing to directly evaporating the restrictions such as the oil return problem of long-range feed flow and the poor performance viscosity of heat conduction wet goods tradition refrigerating medium are large, above two schemes is not preferred version in a lot of occasions.As can be seen here, developing a kind of novel circulation vessel is of great significance for the popularization tool of cascade refrigeration.
Summary of the invention
Of the present invention for the deficiencies in the prior art, a kind of refrigerating circulation vessel is provided, can be applied to the refrigerating circulation of cascade system, as the liquid reservoir in the circulatory system and heat exchanger, use, realized moving without oil of the long-range feed flow of overlapping low-temperature refrigeration system; Can use phase-change working substance as refrigerating medium, avoid adopting heat conduction wet goods refrigerating medium to cause the high problem of system configuration, reduce system cost simultaneously.
For achieving the above object, the present invention by the following technical solutions: a kind of refrigerating circulation vessel, comprise tank body, described tank body top is gas phase zone, bottom is liquid phase region, its inside is provided with back liquid and drench swashs shower nozzle, described time liquid drenches and swashs shower nozzle and be connected with interior circulation liquid return hole; Described tank interior is provided with heat exchange orifice plate, and described heat exchange orifice plate is fixed on inner tank wall; Described tank body gas phase zone sidewall is provided with outer circulation return-air and interior circulation liquid return hole, and described tank body liquid phase region sidewall is provided with outer circulation liquor charging mouth and interior circulation liquid outlet.
Further, the position that described time liquid pouring swashs shower nozzle, heat exchange orifice plate is all positioned at tank body gas phase zone.
Further, described heat exchange orifice plate is positioned at back liquid and drenches sharp shower nozzle below.
Described tank body top is provided with safety valve.
Described tank body gas phase zone sidewall is provided with Pressure gauge, and liquid phase region sidewall is provided with liquid level gauge.
Advantage of the present invention:
1, the present invention has realized with refrigerating circulation and has replaced direct vaporization cycle;
2, the present invention realized long-range low temperature liquid-supplying system without oil circulation, with respect to direct evaporation system, do not deposit when oil condenses obstruction, high temperature at low temperatures the various potential hazards such as oil carbon pollution;
3, the present invention has realized the working medium charging amount that has significantly reduced refrigeration unit, has avoided the excessive situation of expansion vessel volume causing because cryogenic fluid charging amount is large in cascade system;
4, the present invention can use phase-change working substance, has avoided using the unit that the working medium such as conventional heat-conduction oil cause to configure the problems such as high, effectively reduces system cost;
5, the present invention is applicable to the occasion that temperature span of control is larger;
6, structural principle of the present invention is simple, applying flexible.
