Abstract
The utility model discloses a vapor-liquid separator and a refrigerating system. The vapor-liquid separator comprises a primary vapor-liquid separation device and a secondary vapor-liquid separation device; a diaphragm is arranged between the primary vapor-liquid separation device and the secondary vapor-liquid separation device; and an overflow pipe and a vapor balance pipe are arranged on the diaphragm. In the working process, the wet vapor returning from an evaporator firstly enters the primary vapor-liquid separation device, then enters the secondary vapor-liquid separation device, and finally the wet vapor is sucked by a compressor after being discharged from a secondary outlet. The redundant liquid at the bottom of the secondary vapor-liquid separation device can flow back to the primary vapor-liquid separation device at the lower layer from the overflow pipe, the liquid at the upper layer can be ensured not to enter a secondary U-tube, therefore the compressor can be spared of liquid impact, and a siphon can ensure the refrigeration oil to be sucked back to the compressor.
Description
Technical field
The utility model relates to a kind of refrigerating plant, relates in particular to a kind of vapour liquid separator and refrigeration system.
Background technology
Vapour liquid separator is a refrigeration system liquid distributing device commonly used.
As shown in Figure 1, vapour liquid separator of the prior art is vapor-liquid separating device for once, when system is in running order, the moist steam of returning from evaporimeter enters separator by moist steam import 2, liquid and oil are deposited to the vapour liquid separator bottom under the gravity effect, gas enters U type pipe from an import 4 of separator, once exports 5 discharge backs from separator and is sucked by compressor.Refrigerant liquid 3 parts that are deposited to the bottom flash to gas, and another part and oil are penetrated inspiration U type pipe and are atomized the back from spill port 1 together sucks compressor.
There is following shortcoming at least in above-mentioned prior art:
When the refrigeration system operate as normal is no problem, but when quitting work in system, owing to multiple reason can form more liquid in vapour liquid separator, enter U type pipe by spill port, in U type pipe, form full liquid phenomenon, when compressor starts again, liquid in the U type pipe can enter compressor once, thereby cause liquid hammer, refrigerant liquid that U type pipe is outer and oil are after start, enter an import 4 of separator because of pressure reduces a large amount of foams of formation that seethe with excitement rapidly, sucked by compressor and cause liquid hammer 2 times.
The utility model content
The purpose of this utility model provides a kind of vapour liquid separator and the refrigeration system that can avoid compressor is caused liquid hammer.
The purpose of this utility model is achieved through the following technical solutions:
Vapour liquid separator of the present utility model, comprise vapor-liquid separating device one time, a described vapor-liquid separating device is provided with the U-shaped pipe one time, and the top of a described vapor-liquid separating device is provided with the secondary vapor-liquid separating device, and described secondary vapor-liquid separating device is provided with secondary U-shaped pipe;
Be provided with dividing plate between a described vapor-liquid separating device and the secondary vapor-liquid separating device, the once outlet of a described U-shaped pipe penetrates described dividing plate and extend in the described secondary vapor-liquid separating device;
Described dividing plate is provided with the overflow pipe of up/down perforation.
Refrigeration system of the present utility model, this refrigeration system comprises above-mentioned vapour liquid separator.
The technical scheme that is provided by above-mentioned the utility model as can be seen, vapour liquid separator described in the utility model and refrigeration system, because vapour liquid separator comprises vapor-liquid separating device one time, the top of a vapor-liquid separating device is provided with the secondary vapor-liquid separating device, be provided with dividing plate between vapor-liquid separating device and the secondary vapor-liquid separating device, dividing plate is provided with the overflow pipe of up/down perforation.In the course of work, the moist steam of returning from evaporimeter at first enters vapor-liquid separating device one time, enter the secondary vapor-liquid separating device again, discharging the back from the secondary outlet is sucked by compressor, secondary vapor-liquid separating device bottom excess liquid can flow back to vapor-liquid separating device of lower floor from overflow pipe, thereby guarantees that compressor is not by liquid hammer.
Description of drawings
Fig. 1 is the structural representation of vapour liquid separator of the prior art;
Fig. 2 is the structural representation of vapor-liquid separating device of the present utility model.
The specific embodiment
Vapour liquid separator of the present utility model, its preferable specific embodiment comprises vapor-liquid separating device one time as shown in Figure 2, and one time vapor-liquid separating device is provided with the U-shaped pipe one time, the top of a vapor-liquid separating device is provided with the secondary vapor-liquid separating device, and the secondary vapor-liquid separating device is provided with secondary U-shaped pipe;
The once outlet 5 that is provided with 12, U-shaped pipes of dividing plate between vapor-liquid separating device and the secondary vapor-liquid separating device penetrates dividing plate 12 and extend in the secondary vapor-liquid separating device; Dividing plate 12 is provided with the overflow pipe 11 of up/down perforation.
The bottom of secondary U-shaped pipe can be provided with siphon pipe 6, and the end opening of siphon pipe 6 is lower than the suitable for reading of overflow pipe 11.
The bottom of secondary U-shaped pipe can be provided with spill port 9, and the suitable for reading of overflow pipe 11 can be lower than spill port 9, and the suitable for reading of siphon pipe 6 can be higher than spill port 9.
Refrigeration system of the present utility model, its preferable specific embodiment is that this refrigeration system comprises above-mentioned vapour liquid separator.The sidewall of a vapor-liquid separating device of vapour liquid separator is provided with moist steam inlet 2, and the secondary outlet of the secondary U-shaped pipe of vapour liquid separator is moist steam outlet 7; The moist steam inlet is connected with the outlet of the evaporimeter of refrigeration system; The moist steam outlet is connected with the inlet of the compressor of refrigeration system.
Operation principle of the present utility model is:
When system is in running order, the moist steam of returning from evaporimeter enters vapor-liquid separating device one time by moist steam import 2, liquid and oil are deposited to the vapor-liquid separating device bottom one time under the gravity effect, gas enters U type pipe one time from an import 4, enters the secondary vapor-liquid separating device from the once outlet 5 of a U type pipe;
In the secondary vapor-liquid separating device, liquid and oil are deposited to secondary vapor-liquid separating device bottom under the gravity effect, and gas enters secondary U type pipe from secondary import 8, discharge the back from the secondary outlet (moist steam outlet 7) of secondary U type pipe and are sucked by compressor.
In the course of work of the present utility model, after liquid entered vapour liquid separator, the liquid on upper strata can overflow to lower floor by overflow pipe, guarantee that supernatant liquid can not enter in the secondary U type pipe, and siphon pipe can guarantee the sucked back compressor of refrigeration oil.When compressor start, the liquid of lower floor is drawn onto the upper strata and carries out separate and subside, the liquid on upper strata and oil by siphon pipe be inhaled into and atomize after enter compressor.Excess liquid flows back to lower floor from overflow pipe, thereby guarantees compressor not by liquid hammer, can solve refrigeration system and return the liquid problem, avoids compressor is caused liquid hammer.
