Description
(1) technical field
The utility model relates to refrigeration technology field, particularly one evaporation synergy gas-liquid separator.
(2) background technology
The air-cooled heat exchanger of fin that the eighties in 20th century grows up belongs to Refrigeration Technique of new generation, and now extensively model is applied in the refrigeration facility of all trades and professions.
In the refrigeration system of practical application, because degree of supercooling is not enough within the condenser, can flash gas be produced when refrigerant flows through throttling arrangement, after throttling arrangement, originally should present liquid refrigerant just can present gas-liquid mixture phase, cause evaporimeter separatory uneven, thus affect heat transfer effect.
In addition, the difference of tube side can make refrigerant produce the different degrees of superheat at evaporator outlet place.In the tube side of liquid supply rate deficiency, refrigerant can evaporate very soon, and cause the gas converting heat having very long a section before evaporator outlet, heat exchange area can not get effective utilization, just can produce the larger degree of superheat; And in the too much tube side of liquid supply rate, refrigerant only has the very little degree of superheat at evaporator outlet place, even can, with unevaporated liquid, compressor liquid will be caused time serious to amass.
Knockout carries the vital task of uniform distribution refrigerant in evaporimeter, but existing knockout is owing to can not accomplish that separatory is even or make gas-liquid mixed refrigerant enter evaporimeter, refrigerant will be caused to evaporate in evaporator pipeline, and insufficient so that refrigerating efficiency reduces, energy consumption increases, thus causes the instability of refrigeration system.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of low cost of manufacture, heat exchange efficiency is high, evaporation synergy gas-liquid separator that good refrigeration effect, working stability are reliable, easy for installation.
The utility model is achieved by the following technical solution:
A kind of evaporation synergy gas-liquid separator, it is characterized in that, comprise upper cover and low head that the housing of vertical direction and the upper and lower two ends of housing and housing form confined space, feed tube enters enclosure interior from low head, drain pipe enters enclosure interior from upper cover, and the upper end of feed tube is near upper cover, and the lower end of drain pipe is near low head, seal between feed tube and low head, seal between drain pipe and upper cover.
Described upper cover, between low head and housing, between feed tube and low head, between drain pipe and upper cover all by welded seal, described confined space bear pressure more than 0.5Mpa MPa.
The beneficial effects of the utility model are:
By the upper port of feed tube and upper cover at intervals, at intervals, formation is crisscross arranged the utility model for the lower end of drain pipe and low head; Because gas is different from the density of liquid, under same volume, the quality of gas is less than the quality of liquid, liquid in such system and gas will be separated, thus make the liquid refrigerants that is diverted in evaporimeter more even, refrigerant in evaporimeter is evaporated more fully and absorbs extraneous heat, improve refrigerating capacity thus improve refrigerating efficiency.The utility model structure is simple, easy to process, is easy to install, and cost is low.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the utility model structural configuration schematic diagram in refrigeration systems.
In figure, 1 housing, 2 upper covers, 3 low heads, 4 feed tubes, 5 drain pipes, 6 compressors, 7 condensers, 8 expansion valves, 9 knockouts, 10 evaporimeters.
(5) detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1, this kind of evaporation synergy gas-liquid separator, comprise upper cover 2 and low head 3 that the housing 1 of vertical direction and housing about 1 two ends and housing 1 form confined space, upper cover 2 and low head 3 respectively with housing 1 welded seal, confined space bear pressure more than 0.5Mpa MPa; It is inner that feed tube 4 enters housing 1 from low head 3, the upper end of feed tube 4 is near upper cover 2, as long as the distance of feed tube 4 upper end and upper cover 2 ensures not affect liquid and gas flows out from feed tube 4, it is inner that drain pipe 5 enters housing 1 from upper cover 2, the lower end of drain pipe 5 is near low head 3, distance between the lower end of drain pipe 5 and low head 3 only otherwise affecting liquid enters drain pipe 5, drain pipe 5 and feed tube 4 are crisscross arranged in housing 1, by welded seal between feed tube 4 and low head 3, between drain pipe 5 and upper cover 2, pass through welded seal.
The course of work is as follows: as shown in Figure 2, circulate compressor 6, condenser 7, expansion valve 8, the utility model, knockout 9, evaporimeter 10, compressor 6 connection successively, wherein housing 1 above-below direction of the present utility model is placed, feed tube 4 under, drain pipe 5 is upper, feed tube 4 is connected with expansion valve 8, and drain pipe 5 is connected with knockout 9; Cold-producing medium becomes the gas of HTHP in compressor 6 after overcompression, then enter condenser 7 and carry out condensation, become supercooled state, through the effect of expansion valve 8 reducing pressure by regulating flow, become gas-liquid two-phase and enter housing 1 from feed tube 4, because gas is different from the density of liquid, under same volume, the quality of gas is less than the quality of liquid, makes gas and fluid separation applications, and liquid refrigerants is deposited to the bottom of housing 1, gas rises to the top of housing 1, and gas becomes liquid after first becoming gas-liquid two-phase.The refrigerant entering evaporimeter 10 like this from drain pipe 5 to knockout 9 is liquid.Thus when the liquid refrigerants be diverted in evaporimeter 10 is coexisted than gas-liquid two-phase distribute more even, refrigerant in evaporimeter 10 is evaporated more fully and absorbs extraneous heat, overheated gas is become through heat absorption, flow into compressor 6 and complete circulation, thus raising refrigerating capacity, and then improve refrigerating efficiency.
Except technical characteristic described in description, all the other technical characteristics are those skilled in the art's known technology.
