Take the present technique solution, the heating condensate does not need external heat source, does not have the potential safety hazard of the detonation of similar electric heating, and long-pending oil groove has played the effect of condenser simultaneously, has strengthened the cooling effect of refrigeration system, has improved refrigerating efficiency.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Description of drawings
Fig. 1 is the structural representation that oil gas of the present invention reclaims evaporimeter.
Fig. 2 is the left view of Fig. 1.
Among the figure, 1 is evaporator body, and 2 is refrigerant inlet, and 3 is refrigerant outlet, and 4 is oil and gas import, and 5 is waste gas outlet, and 6 are long-pending oil groove, and 7 is the condensate discharge pipe, and 8 is passage, and 9 is dividing plate, and 10 are hot air intake, and 11 is cold liquid outlet.
The specific embodiment
Like Fig. 1 and Fig. 2; Oil gas of the present invention reclaims evaporimeter, comprise the waste gas after plate-fin evaporator body 1, the refrigerant inlet 2, the refrigerant outlet 3 that links to each other with compressor suction that link to each other with the throttle mechanism outlet, the oil and gas import 4, the discharge that supply oil gas to be recycled to get into recycle waste gas outlet 5, be in long-pending oil groove 6 and condensate discharge pipe 7 that the evaporator body bottom is used to collect condensate, refrigerant inlet 2 is communicated with through coolant channel in evaporator body 1 with refrigerant outlet 3; The coolant channel outside is a gas channel; This is the universal architecture of dividing wall type heat exchanger, and gas channel top connects oil and gas import 4, and the bottom connects long-pending oil groove 6; Long-pending oil groove 6 bottoms or on the lower side portion connect condensate discharge pipe 7; Sidewall or on the upper side portion connect waste gas outlet 5, stockpile in long-pending oil groove 6 bottoms to guarantee condensation is separated out from oil gas oil and moisture, discharge and reclaim from discharge pipe 7; The waste gas that can not condense is discharged from waste gas outlet 5; Also has the passage 8 that heat supply gas passes through in the long-pending oil groove 6, the cold liquid outlet 11 of these passage one termination hot air intake 10, one terminations.The direct high temperature refrigerant steam that comes from compressor of a part is from hot air intake 10 admission passages 8; Condensate and moisture in the long-pending oil groove 6 of heating make its temperature remain on the above freezing of water, in case moisture freezes and stops up condensate discharge pipe 7; Refrigerant vapour self then heat release is condensed into liquid; Be generally subcooled liquid, leave passage 8, return kind of refrigeration cycle from cold liquid outlet 11.
Passage 8 in the long-pending oil groove 6 can possible arbitrarily mode form, and for example adopts double wall or compound wall structure, as long as the high temperature refrigerant steam that comes from compressor is passed through, gets final product with condensate and moisture in the long-pending oil groove 6 of partition heat exchange mode heating.A kind of method is: in long-pending oil groove 6, establish the dividing plate 9 that is complementary with its bottom transverse cross-sectional shape; Dividing plate 9 surrounds with long-pending oil groove 6 bottom peripheral seal and forms an enclosure space, offers hot air intake 10 in this enclosure space one side, and cold liquid outlet 11 is offered in another position; Condensate discharge pipe 7 passes this enclosure space; Condensate discharge pipe 7 suitable for reading opening at dividing plate 9 upper surfaces, end opening are stretched out long-pending oil groove 6 bottoms, and condensate and moisture in the long-pending oil groove 6 are discharged through condensate discharge pipe 7 smoothly.
The condensing type oil gas retracting device comprises compressor, condenser, throttle mechanism and evaporimeter, and low-temperature refrigerant gas becomes high-temperature gas through compressor compresses, is condensed into middle geothermal liquid through the condenser heat release; Become cryogenic liquid through the throttle mechanism throttling again; Get into evaporimeter, absorb the heat of oil gas, flash to cryogenic gas; Get back to compressor and carry out next kind of refrigeration cycle, thereby realize condensing and recycling oil gas.
When the condensing type oil gas retracting device of employing evaporimeter of the present invention is in oil gas recovery operation state; Get into the coolant channel of evaporimeters 1 from refrigerant inlet 2 from the next liquid refrigerant of throttle mechanism; Absorb the heat of oil gas through the partition heat exchange; Be evaporated to gaseous state, leave evaporimeter 1, get back to compressor from refrigerant outlet 3; Oil gas to be recycled gets into the gas channel of evaporimeter 1 from oil and gas import 4; Be cooled to below-70 ℃ even-110 ℃; Be condensed into fluid oil, converge, discharge and reclaim from condensate outlet 7 into long-pending oil groove 6; The waste gas that residue can not liquefy is discharged from waste gas outlet 5, thereby realizes the recycling of oil gas.Be condensed into liquid from a part of condenser that gets into refrigeration system of the high-temperature gas of compressor discharge and be discharged into throttle mechanism, then from hot air intake 10 admission passages 8 of evaporimeter, condensate and the moisture in the oil groove 6 is amassed in heating to another part; Make the temperature of condensate and moisture remain on the above freezing of water, in case moisture freezes and stops up condensate discharge pipe 7, refrigerant vapour then heat release itself is condensed into liquid; Be generally subcooled liquid; Leave passage 8 from cold liquid outlet 11, be discharged into throttle mechanism, return kind of refrigeration cycle; This moment, passage 8 one side played heating condensate and moisture; Be equivalent to an additional condenser simultaneously, make high temperature refrigerant obtain better condensation, can improve the refrigerating efficiency of whole refrigeration system.
