Description

Technical Field

[0001] The present disclosure relates to the technical field of phosphoric acid production, and particularly to a liquid-phase cooling device and a circulating refrigeration device. Background Art

[0002] In the production of refined phosphoric acid, evaporation and concentration are often used for purification. However, a large amount of water vapor is generated in this process. To improve the utilization rate of water resources and reduce waste, the water vapor is usually cooled and reused. Therefore, in order to improve the cooling effect on the water vapor, some manufacturers have conducted research and development.

[0003] For example, Chinese Patent Document CN219462556U discloses a new type of pipeline gas-phase condenser, which includes a pipeline body. One side of the pipeline body is connected with an inlet pipe and a refrigerant inlet pipe, and the other side of the pipeline body is connected with an outlet pipe and a refrigerant discharge pipe. A connecting pipe in a spiral structure is fixedly connected inside the pipeline body, and the sides of the discharge pipe and the inlet pipe facing each other are respectively connected with both sides of the connecting pipe.

[0004] However, the design of the above new type of pipeline gas-phase condenser has the following problems:

[0005] For the above new type of pipeline gas-phase condenser, although heat exchange can be achieved by the contact between the connecting pipe and the pipeline body for cooling, since the refrigerant is prone to absorb heat and undergo a phase change during the cooling process, for example, from a liquid-phase refrigerant to a gas-phase refrigerant, the liquid-phase refrigerant and the gas-phase refrigerant are mixed together in the pipeline body. The gas-phase refrigerant, due to its lower density than the liquid-phase refrigerant, will float along the pipeline body and disrupt the flow direction of the liquid-phase refrigerant, resulting in the situation of the liquid-phase refrigerant flowing unevenly, and ultimately reducing the cooling efficiency. Summary of the Utility Model

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a liquid-phase cooling device and a circulating refrigeration device with stable refrigerant flow direction and high cooling efficiency.

[0007] The purpose of the present disclosure is achieved through the following technical solutions:

[0008] A liquid-phase cooling device includes a material conduit and a heat exchange cylinder. A refrigerant liquid cavity is provided inside the heat exchange cylinder. The material conduit is arranged in the refrigerant liquid cavity. The feed port of the material conduit extends out of the first end of the heat exchange cylinder, and the discharge port of the material conduit extends out of the second end of the heat exchange cylinder;

[0009] The liquid-phase cooling device further includes an outer sleeve and a plurality of vent pipes;

[0010] The outer sleeve is sleeved outside the heat exchange tube, and a refrigerant gas chamber is formed between the outer sleeve and the heat exchange tube; a plurality of the drain pipes are all arranged in the refrigerant gas chamber, the intake ends of the plurality of the drain pipes are distributed at intervals on the heat exchange tube and are respectively communicated with the refrigerant liquid chamber; the exhaust ends of the plurality of the drain pipes are respectively communicated with the refrigerant gas chamber.

[0011] In one embodiment, the plurality of the drain pipes are arranged at intervals from the first end of the heat exchange tube to the second end of the heat exchange tube.

[0012] In one embodiment, the plurality of the drain pipes are all arranged at the top of the circumferential wall of the heat exchange tube.

[0013] In one embodiment, the exhaust end of the drain pipe forms an exhaust port, and a one-way exhaust valve is arranged in the exhaust port.

[0014] In one embodiment, the tube wall of the material conduit located in the refrigerant liquid chamber protrudes radially to form heat dissipation ribs, a heat exchange chamber is formed in the heat dissipation ribs, and the heat exchange chamber is communicated with the inside of the material conduit.

[0015] In one embodiment, the number of the heat dissipation ribs is at least two, and the at least two heat dissipation ribs are distributed at intervals along the circumferential direction of the material conduit.

[0016] In one embodiment, the heat dissipation ribs extend along the axial direction of the material conduit.

[0017] A circulating refrigeration device includes a refrigerator and the liquid-phase cooling device of any one of the above embodiments; the refrigerant outlet of the refrigerator is communicated with the first end of the heat exchange tube, the refrigerant inlet of the refrigerator is communicated with the second end of the heat exchange tube, and the first end of the heat exchange tube is communicated with the second end of the heat exchange tube through the refrigerant liquid chamber.

[0018] In one embodiment, a gas-liquid separator is further arranged between the refrigerator and the liquid-phase cooling device; the refrigerant inlet pipe of the gas-liquid separator is communicated with the refrigerant outlet of the refrigerator, and the liquid-phase outlet pipe of the gas-liquid separator is communicated with the first end of the heat exchange tube.

[0019] In one embodiment, a gas-phase refrigerant inlet and a gas-phase refrigerant outlet are respectively opened at both ends of the outer sleeve, and the gas-phase refrigerant inlet is communicated with the gas-phase refrigerant outlet through the refrigerant gas chamber; the gas-phase refrigerant inlet is close to the first end of the heat exchange tube and is communicated with the gas-phase outlet pipe of the gas-liquid separator; the gas-phase refrigerant outlet is close to the second end of the heat exchange tube and is communicated with the refrigerant inlet.

[0020] Compared with the prior art, the present disclosure has at least the following advantages:

[0021] 1) Since the material conduit is disposed in the refrigerant liquid chamber, the liquid-phase refrigerant in the refrigerant liquid chamber can come into contact with the material conduit. When water vapor moves from the inlet of the material conduit to the outlet of the material conduit, the water vapor will exchange heat fully with the liquid-phase refrigerant and be cooled. Also, since a number of vent pipes are disposed in the refrigerant gas chamber between the outer sleeve and the heat exchange cylinder, by connecting the inlet ends of the number of vent pipes to the refrigerant liquid chamber respectively and the outlet ends of the number of vent pipes to the refrigerant gas chamber respectively, the gaseous refrigerant generated by heat absorption in the liquid-phase refrigerant can enter the refrigerant gas chamber through the vent pipes, so as to discharge the gaseous refrigerant mixed in the liquid-phase refrigerant in a timely manner.

[0022] 2) Compared with the novel pipeline gas-phase condenser of the prior art, the liquid-phase cooling device of the present disclosure can timely empty the gaseous refrigerant generated in the refrigerant liquid chamber into the refrigerant gas chamber through a number of vent pipes, thereby avoiding the interference of the gaseous refrigerant mixed in the liquid-phase refrigerant on the flow of the liquid-phase refrigerant and finally reducing the occurrence of the situation of the liquid-phase refrigerant having uneven flow.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0034] Such as Figure 1 And Figure 2As shown, a liquid-phase cooling device 100 of an embodiment includes a material conduit 110, a heat exchange cylinder 120, an outer sleeve 130, and a plurality of vent pipes 140; a refrigerant liquid chamber 1210 is formed inside the heat exchange cylinder 120, the material conduit 110 is disposed inside the refrigerant liquid chamber 1210, the feed port 1110 of the material conduit 110 extends out of the first end of the heat exchange cylinder 120, and the discharge port 1120 of the material conduit 110 extends out of the second end of the heat exchange cylinder 120; the outer sleeve 130 is sleeved outside the heat exchange cylinder 120, and a refrigerant gas chamber 13a is formed between the outer sleeve 130 and the heat exchange cylinder 120; a plurality of vent pipes 140 are all disposed inside the refrigerant gas chamber 13a between the outer sleeve 130 and the heat exchange cylinder 120, the intake ends of the plurality of vent pipes 140 are spaced apart and distributed on the heat exchange cylinder 120 and are respectively communicated with the refrigerant liquid chamber 1210; the exhaust ends of the plurality of vent pipes 140 are respectively communicated with the refrigerant gas chamber 13a.

[0035] It can be understood that since the material conduit 110 is disposed inside the refrigerant liquid chamber 1210, the liquid-phase refrigerant in the refrigerant liquid chamber 1210 can contact the material conduit 110. When the water vapor moves from the feed port 1110 of the material conduit 110 to the discharge port 1120 of the material conduit 110, the water vapor will exchange heat with the liquid-phase refrigerant sufficiently and be cooled. Also, because a plurality of vent pipes 140 are disposed inside the refrigerant gas chamber 13a between the outer sleeve 130 and the heat exchange cylinder 120, by making the intake ends of the plurality of vent pipes 140 be respectively communicated with the refrigerant liquid chamber 1210 and the exhaust ends of the plurality of vent pipes 140 be respectively communicated with the refrigerant gas chamber 13a, the gaseous refrigerant generated by the liquid-phase refrigerant absorbing heat can enter the refrigerant gas chamber 13a through the vent pipes 140, so that the gaseous refrigerant mixed in the liquid-phase refrigerant can be discharged in time.

[0036] It can be understood that compared with the new pipeline gas-phase condenser of the prior art, the liquid-phase cooling device 100 of this embodiment can timely empty the gaseous refrigerant generated in the refrigerant liquid chamber 1210 into the refrigerant gas chamber 13a through a plurality of vent pipes 140, thereby avoiding the gaseous refrigerant mixing in the liquid-phase refrigerant and interfering with the flow of the liquid-phase refrigerant, and finally reducing the occurrence of the situation of the liquid-phase refrigerant having uneven flow.

[0037] Combined with Figure 2As shown, in one embodiment, a plurality of vent pipes 140 are arranged at intervals from the first end of the heat exchange cylinder 120 to the second end of the heat exchange cylinder 120. It can be understood that since the feed port 1110 of the material conduit 110 extends out of the first end of the heat exchange cylinder 120 and the discharge port 1120 of the material conduit 110 extends out of the second end of the heat exchange cylinder 120, when water vapor moves from the feed port 1110 of the material conduit 110 to the discharge port 1120 of the material conduit 110, the water vapor will move from the first end of the heat exchange cylinder 120 to the second end of the heat exchange cylinder 120, thereby exchanging heat with the liquid-phase refrigerant in the heat exchange cylinder 120. The liquid-phase refrigerant will generate a gas-phase refrigerant at both ends and the middle of the heat exchange cylinder 120 after heat exchange. By arranging a plurality of vent pipes 140 at intervals from the first end of the heat exchange cylinder 120 to the second end of the heat exchange cylinder 120, the gas-phase refrigerant generated in each part of the heat exchange cylinder 120 can be discharged in time through the corresponding vent pipes 140.

[0038] Combined with Figure 2 As shown, in one embodiment, a plurality of vent pipes 140 are all arranged at the top of the peripheral wall of the heat exchange cylinder 120. It can be understood that when the liquid-phase refrigerant in the refrigerant liquid chamber 1210 absorbs heat and becomes a gas-phase refrigerant, since the density of the gas-phase refrigerant is lighter than that of the liquid-phase refrigerant, the gas-phase refrigerant will float above the liquid-phase refrigerant, that is, the gas-phase refrigerant finally converges at the top of the refrigerant liquid chamber 1210. By arranging a plurality of vent pipes 140 at the top of the peripheral wall of the heat exchange cylinder 120, the intake ends of the plurality of vent pipes 140 are respectively communicated with the refrigerant liquid chamber 1210, so that the converged gas-phase refrigerant can be more fully emptied through the plurality of vent pipes 140.

[0039] Combined with Figure 2 And Figure 3 As shown, in this embodiment, the exhaust end of the vent pipe 140 forms an exhaust port 1410, and a one-way exhaust valve 1411 is arranged in the exhaust port 1410. It can be understood that by arranging a one-way exhaust valve 1411 in the exhaust port 1410, the gas-phase refrigerant generated in the refrigerant liquid chamber 1210 can be discharged to the refrigerant gas chamber 13a through the exhaust port 1410, and at the same time, it can prevent the gas-phase refrigerant in the refrigerant gas chamber 13a from flowing back into the refrigerant liquid chamber 1210 and weakening the cooling effect of the liquid-phase refrigerant.

[0040] Combined with Figure 3 And Figure 4As shown, in one embodiment, the tube wall of the material conduit 110 located in the refrigerant liquid chamber 1210 protrudes radially to form heat dissipation ribs 1130, and a heat exchange chamber 113a is formed inside the heat dissipation ribs 1130. The heat exchange chamber 113a communicates with the inside of the material conduit 110. It can be understood that by making the heat dissipation ribs 1130 located in the refrigerant liquid chamber 1210 protrude radially from the tube wall of the material conduit 110, the contact area between the material conduit 110 and the liquid-phase refrigerant in the refrigerant liquid chamber 1210 can be increased. Since the heat exchange chamber 113a formed inside the heat dissipation ribs 1130 communicates with the inside of the material conduit 110, the water vapor in the material conduit 110 can enter the heat exchange chamber 113a, and the water vapor can contact and exchange heat with the liquid-phase refrigerant in the heat exchange chamber 113a, ultimately accelerating the cooling process of the water vapor.

[0041] Combined with Figure 3 As shown, in this embodiment, the number of the heat dissipation ribs 1130 is at least two, and at least two heat dissipation ribs 1130 are spaced apart along the circumferential direction of the material conduit 110. It can be understood that by making at least two heat dissipation ribs 1130 spaced apart along the circumferential direction of the material conduit 110, the material conduit 110 can contact the liquid-phase refrigerant more fully in the circumferential direction through the heat dissipation ribs 1130, and further improve the cooling effect of the liquid-phase refrigerant on the water vapor. Combined with Figure 4 As shown, specifically, the number of the heat dissipation ribs 1130 is four, and the four heat dissipation ribs 1130 are equally arc-distributed along the circumferential wall of the material conduit 110, so that the contact area between the material conduit 110 and the liquid-phase refrigerant at each circumferential part can tend to be consistent, that is, to ensure that the water vapor in the material conduit 110 can be cooled synchronously and uniformly in the circumferential direction, and ultimately improve the overall cooling effect on the water vapor.

[0042] Combined with Figure 2 With Figure 4 As shown, further, the heat dissipation ribs 1130 extend along the axial direction of the material conduit 110. It can be understood that by making the heat dissipation ribs 1130 extend along the axial direction of the material conduit 110, during the whole process of the water vapor moving from the feed port 1110 of the material conduit 110 to the discharge port 1120 of the material conduit 110, the water vapor can exchange heat with the liquid-phase refrigerant in the refrigerant liquid chamber 1210 through the heat dissipation ribs 1130, so that the water vapor and the liquid-phase refrigerant are in full contact, and further improve the cooling effect of the liquid-phase refrigerant on the water vapor.

[0043] Combined with Figure 2 With Figure 5As shown, the present disclosure also provides a cycle refrigeration device 10, including a refrigerator 200 and the liquid-phase cooling device 100 of any of the above embodiments; the refrigerant outlet 210 of the refrigerator 200 is communicated with the first end of the heat exchange cylinder 120, the refrigerant inlet 220 of the refrigerator 200 is communicated with the second end of the heat exchange cylinder 120, and the first end of the heat exchange cylinder 120 is communicated with the second end of the heat exchange cylinder 120 through the refrigerant liquid chamber 1210. It can be understood that since the first end of the heat exchange cylinder 120 is communicated with the refrigerant outlet 210 of the refrigerator 200, the liquid-phase refrigerant in the refrigerator 200 can enter the first end of the heat exchange cylinder 120 through the refrigerant outlet 210. The liquid-phase refrigerant flows from the first end of the heat exchange cylinder 120 to the second end of the heat exchange cylinder 120 through the refrigerant liquid chamber 1210 and exchanges heat with the material conduit 110. By making the second end of the heat exchange cylinder 120 communicate with the refrigerant inlet 220 of the refrigerator 200, the heat-exchanged liquid-phase refrigerant can flow back into the refrigerator 200 through the refrigerant inlet 220 for reuse. Finally, the liquid-phase refrigerant circulates between the refrigerator 200 and the heat exchange cylinder 120, so as to continuously cool the water vapor in the material conduit 110.

[0044] Combined with Figure 2 and Figure 5 As shown, in one of the embodiments, a gas-liquid separator 300 is further provided between the refrigerator 200 and the liquid-phase cooling device 100; the refrigerant inlet pipe 310 of the gas-liquid separator 300 is communicated with the refrigerant outlet 210 of the refrigerator 200, and the liquid-phase outlet pipe 330 of the gas-liquid separator 300 is communicated with the first end of the heat exchange cylinder 120. It can be understood that since the refrigerant outlet 210 of the refrigerator 200 is communicated with the refrigerant inlet pipe 310 of the gas-liquid separator 300, the liquid-phase refrigerant in the refrigerator 200 will first enter the gas-liquid separator 300 through the refrigerant inlet pipe 310. The gas-liquid separator 300 can separate the gas-phase refrigerant generated during the flow of the liquid-phase refrigerant, thereby purifying the liquid-phase refrigerant. By making the liquid-phase outlet pipe 330 of the gas-liquid separator 300 communicate with the first end of the heat exchange cylinder 120, the purified liquid-phase refrigerant can enter the refrigerant liquid chamber 1210 of the heat exchange cylinder 120 through the liquid-phase outlet pipe 330, and the purified liquid-phase refrigerant can cool the material conduit 110 more efficiently.

[0045] Combined with Figure 2 and Figure 5As shown, further, a vapor refrigerant inlet 1310 and a vapor refrigerant outlet 1320 are respectively provided at both ends of the outer sleeve 130. The vapor refrigerant inlet 1310 is communicated with the vapor refrigerant outlet 1320 through the refrigerant gas chamber 13a. The vapor refrigerant inlet 1310 is close to the first end of the heat exchange cylinder 120 and is communicated with the vapor outlet pipe 320 of the gas-liquid separator 300. The vapor refrigerant outlet 1320 is close to the second end of the heat exchange cylinder 120 and is communicated with the refrigerant inlet 220. It can be understood that by connecting the vapor outlet pipe 320 of the gas-liquid separator 300 to the vapor refrigerant inlet 1310 of the outer sleeve 130, the vapor refrigerant separated by the gas-liquid separator 300 can enter the refrigerant gas chamber 13a of the outer sleeve 130 through the vapor refrigerant inlet 1310. Since the vapor refrigerant inlet 1310 is close to the first end of the heat exchange cylinder 120 and the vapor refrigerant outlet 1320 is close to the second end of the heat exchange cylinder 120, when the vapor refrigerant flows from the vapor refrigerant inlet 1310 to the vapor refrigerant outlet 1320, the vapor refrigerant will contact and exchange heat with both ends and the middle of the heat exchange cylinder 120 at the same time. Because the vapor refrigerant separated by the gas-liquid separator 300 has a lower pressure and temperature than the vapor refrigerant generated in the heat exchange cylinder 120, the generation of the vapor refrigerant in the heat exchange cylinder 120 can be slowed down through heat exchange. And by connecting the vapor refrigerant outlet 1320 to the refrigerant inlet 220 of the refrigerator 200, the vapor refrigerant can be recycled back into the refrigerator 200 for reuse, improving the utilization rate of the refrigerant and reducing waste.

[0046] In one of the embodiments, for better understanding, the usage process of the liquid-phase cooling device 100 in the above embodiment is described as follows:

[0047] Combined with Figure 2 As shown, first, the feed port 1110 of the material conduit 110 is connected to the water vapor generated by the evaporation and concentration of phosphoric acid. The water vapor moves from the feed port 1110 of the material conduit 110 to the discharge port 1120 of the material conduit 110. The water vapor fully contacts and exchanges heat with the liquid-phase refrigerant in the refrigerant liquid chamber 1210 during the flow process. The vapor refrigerant generated by the liquid-phase refrigerant absorbing heat enters the refrigerant gas chamber 13a through the vent pipe 140, so that the vapor refrigerant in the refrigerant liquid chamber 1210 can be emptied in time, reducing the occurrence of uneven flow in the refrigerant liquid chamber 1210.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1) Since the material conduit 110 is disposed within the refrigerant liquid chamber 1210, the liquid-phase refrigerant within the refrigerant liquid chamber 1210 will be able to come into contact with the material conduit 110. When water vapor moves from the inlet 1110 of the material conduit 110 towards the outlet 1120 of the material conduit 110, the water vapor will exchange heat fully with the liquid-phase refrigerant and be cooled. Also, because a number of vent pipes 140 are disposed within the refrigerant gas chamber 13a between the outer sleeve 130 and the heat exchange cylinder 120, by connecting the inlet ends of the number of vent pipes 140 to the refrigerant liquid chamber 1210 respectively and the exhaust ends of the number of vent pipes 140 to the refrigerant gas chamber 13a respectively, the gas-phase refrigerant generated by the liquid-phase refrigerant absorbing heat will be able to enter the refrigerant gas chamber 13a through the vent pipes 140, thereby being able to timely discharge the gas-phase refrigerant mixed in the liquid-phase refrigerant.

[0050] 2) Compared with the existing new pipeline gas-phase condenser, the liquid-phase cooling device 100 of the present disclosure can timely empty the gas-phase refrigerant generated within the refrigerant liquid chamber 1210 into the refrigerant gas chamber 13a through a number of vent pipes 140, thereby avoiding the gas-phase refrigerant mixing in the liquid-phase refrigerant and causing interference to the flow of the liquid-phase refrigerant, and ultimately reducing the occurrence of the situation of the liquid-phase refrigerant having uneven flow.

[0051] The above-described embodiments merely represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
