Abstract
The utility model discloses a thermal siphon vaporizing device, including a gas and liquid separator, a dry evaporator, a liquid falling pipe and an air inlet pipe. The dry evaporator is equipped under the gas and liquid separator which comprise an inner chamber and provided with an air outlet pipe. The liquid falling pipe is arranged at the position near one end of the gas and liquid separator and the dry evaporator. The upper end of the liquid falling pipe is communicated with the bottom of the gas and liquid separator and the lower end is communicated with the dry evaporator. The air inlet pipe is arranged at the position adjacent to the other end of the gas and liquid separator and the dry evaporator. The upper end of the air inlet pipe is communicated with the gas and liquid separator and the lower end is communicated with the dry evaporator. The upper end of the liquid falling pipe is arranged in the inner chamber of the gas and liquid separator. Adopting the utility model, the liquid falling pipe extending into the inner chamber of the gas and liquid separator can limit the refrigeration oil in the gas and liquid separator, not flowing into the dry evaporator so as to ensure heat exchange efficiency of the evaporation coil of the dry evaporator not to be influenced.
Description
Technical field
The utility model relates to a kind of vaporising device that uses in the indirect type refrigeration system at ammonia.
Background technology
The thermal siphon vaporising device mainly comprises dry evaporator and is positioned at the gas-liquid separator on dry evaporator top.Different with traditional horizontal-type evaporator, the tube side of dry evaporator is a coolant channel, and the pipe shell journey is the refrigerating medium passage.Liquid circulation in dry evaporator and the gas-liquid separator relies on the head of liquid of cold-producing medium and the thermal siphon phenomenon of density contrast generation to carry out.Yet, in existing thermal siphon vaporising device, when the cold-producing medium in the gas-liquid separator flows into dry evaporator, tend to make the refrigeration oil that is mingled with in the cold-producing medium also along with cold-producing medium flow in the evaporation coil of dry evaporator together, thereby can increase the thermal resistance of evaporation coil, reduce heat exchange efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of thermal siphon vaporising device, and this thermal siphon vaporising device can significantly reduce the refrigeration oil quantity from gas-liquid separator inflow dry evaporator.
The technical scheme that the utility model adopted is: a kind of thermal siphon vaporising device comprises gas-liquid separator, dry evaporator, declining liquid tube and air inlet pipe; Wherein, dry evaporator is arranged on the below of gas-liquid separator, and gas-liquid separator comprises an inner cavity chamber, is provided with escape pipe on gas-liquid separator; Declining liquid tube is arranged on the position near gas-liquid separator and dry evaporator one end, and the upper end of declining liquid tube is connected with the bottom of gas-liquid separator, and the lower end is communicated with dry evaporator; Air inlet pipe is arranged on the position near the gas-liquid separator and the dry evaporator other end, and the upper end of air inlet pipe is communicated with gas-liquid separator, and the lower end is communicated with dry evaporator; The upper end of declining liquid tube is arranged in the inner cavity chamber of gas-liquid separator.
After adopting technique scheme, the declining liquid tube that extend in the gas-liquid separator inner cavity chamber can make it can not flow into dry evaporator with freezing oil catch in gas-liquid separator, thereby the heat exchange efficiency of evaporation coil that can guarantee dry evaporator is unaffected.

Figure 1A is a structural representation of the present utility model;
Figure 1B is the side view of Figure 1A;
Fig. 2 is the local enlarged diagram of the P part of Figure 1A.
The specific embodiment
Figure 1A and 1B show the structural representation of thermal siphon vaporising device.As shown in the figure, the thermal siphon vaporising device comprises gas-liquid separator 1, dry evaporator 2, declining liquid tube 3 and air inlet pipe 4.Wherein, declining liquid tube 3 is arranged on the position near gas-liquid separator 1 and dry evaporator 2 one ends, and the upper end of declining liquid tube 3 is connected with the bottom of gas-liquid separator 1, and the lower end is communicated with dry evaporator 2.Air inlet pipe 4 is arranged on the position near the gas-liquid separator 1 and dry evaporator 2 other ends, and the upper end of air inlet pipe 4 is communicated with gas-liquid separator 1, and the lower end is communicated with dry evaporator 2.Also be provided with escape pipe 11 on gas-liquid separator 1, the gas-liquid separator top is different with in the prior art escape pipe being arranged on, and this escape pipe 11 is arranged on the side of gas-liquid separator 1, thereby has solved the superelevation problem in the equipment transportation effectively.
Behind the refrigerant liquid inflow gas-liquid separator 1 of evaporative condenser inflow, flow in the evaporation coil of dry evaporators 2 through declining liquid tube 3.The cold-producing medium evaporation of in evaporation coil, absorbing heat, part steam enters into by air inlet pipe 4 and carries out gas-liquid separation in the gas-liquid separator 1, and gas is taken away by escape pipe 11 cooled compressors, flow into dry evaporator 2 after liquid is separated and circulates once more.
As shown in Figure 2, gas-liquid separator 1 comprises an inner cavity chamber 12.Main improvements of the present utility model are that the upper end of declining liquid tube 3 is arranged in the inner cavity chamber 12 of gas-liquid separator 1.That is to say have one section declining liquid tube to stretch in the inner cavity chamber 12, this part declining liquid tube is convexly set on the bottom interior wall of gas-liquid separator 1, plays the effect of baffle plate.Because the density of refrigeration oil is greater than cold-producing medium, therefore be mixed in refrigeration oil in the cold-producing medium and can be deposited on the bottom of gas-liquid separator 1, and the declining liquid tube that reaches in the inner cavity chamber 12 exactly can make it can not flow into dry evaporator 2 with freezing oil catch in gas-liquid separator 1.In a kind of preferred implementation, the declining liquid tube length H that is positioned at inner cavity chamber 12 is 3mm～5mm.
