Description

Technical Field

[0001] The present application relates to the field of condensers, and in particular to a separate condenser. Background Art

[0002] Currently, the cooling circulation system widely used in the fine chemical industry generally consists of three core components: the cooling tower, the circulating pump station, and the condenser. The operating efficiency and effectiveness of this system largely depend on the performance of the weakest link among these three components. In other words, the heat exchange capacity is directly limited by the lowest limiting factor among the three. Specifically, the cooling tower is responsible for dissipating heat from the circulating water to the atmosphere, the circulating pump station ensures the continuous and stable flow of cooling water within the system, and the condenser is the key equipment for heat transfer, which is directly related to the thermal energy management efficiency of the production process.

[0003] However, in the heat exchange process of existing condensers, it is common that when gas and liquid undergo heat exchange reaction in the same channel, although the gas effectively absorbs the heat released by the liquid, it also carries a certain amount of water vapor with it and leaves in the process. This not only reduces the efficiency of heat exchange, but more importantly, it leads to direct evaporation of water, thereby wasting water resources. Utility Model Content

[0004] In view of this, the present application proposes a separate condenser, comprising: a cavity, an air heat exchange tube and a liquid heat exchange tube.

[0005] A material inlet is provided on one side of the cavity in the length direction, and a material outlet is provided at the bottom of the cavity, and the material outlet is provided on the side away from the material inlet; a gas phase inlet and a gas phase outlet are provided on the side of the cavity close to the material inlet, and the two ends of the gas heat exchange pipe are respectively connected to the gas phase inlet and the gas phase outlet; a liquid phase outlet and a liquid phase inlet are provided on the other side of the cavity in the length direction, and the two ends of the liquid heat exchange pipe are respectively connected to the liquid phase outlet and the liquid phase inlet.

[0006] In a possible implementation, the gas phase inlet is arranged at the bottom of the cavity, and the gas phase outlet is arranged at the top of the cavity.

[0007] In a possible implementation, a partition is further included, which is arranged between the gas heat exchange tube and the liquid heat exchange tube, and a preset distance is formed between the top and bottom of the partition and the inner wall of the cavity.

[0008] In one possible implementation, the gas heat exchange tube is a straight tube, a coil or a spiral tube.

[0009] In one possible implementation, the liquid heat exchange tube is a U-shaped tube, a coil or a spiral tube.

[0010] In a possible implementation, the liquid phase outlet is arranged on the top of the liquid phase inlet.

[0011] In one possible implementation, baffles are provided between the liquid heat exchange tubes.

[0012] In one possible implementation, a through hole is provided on the partition.

[0013] In one possible implementation, the ratio of the height of the partition to the height inside the cavity is 2:5-4:5, and the height of the partition is greater than the height of the liquid heat exchange tube; the ratio of the liquid heat exchange tube to the length of the cavity is 1:3-1:2.

[0014] In a possible implementation, a baffle is provided between the bottom of the liquid heat exchange tube and the bottom of the cavity, and the material outlet is provided at the bottom of the baffle.

[0015] The beneficial effects of the present application are as follows: when the high-temperature material enters the cavity, it first passes through the air heat exchange pipe near the inlet end of the high-temperature material, and then transfers the heat to the air in the air heat exchange pipe after passing through the air heat exchange pipe. Therefore, the cold air entering the air circulation heat exchange area will take away part of the heat in the material and become hot air, which is discharged through the gas phase outlet. The material after heat exchange through the air heat exchange pipe is then heat exchanged through the liquid heat exchange pipe, and the low-temperature material after heat exchange is discharged through the material outlet. The high-temperature material first passes through the air heat exchange pipe to take away part of the heat, thereby reducing the temperature of the circulating water at the liquid phase outlet and reducing the cooling burden on the cooling tower. The heat taken away can also be used as a heat source for heating or pipeline heating. At the same time, the present application can completely separate the gas and circulating water. While the gas takes away the heat, it will not cause volatilization loss of the circulating water, thus having a water-saving effect.

[0022] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0023] In addition, numerous specific details are provided in the detailed description below to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0024] The separate condenser of this application is used to be connected to the cooling tower in a loop. The high-temperature material exchanges heat through the condenser, and the circulating water in the condenser is used to be transmitted to the cooling tower for heat exchange. When the temperature is low in winter, the cooling efficiency of the cooling tower is high, while when the temperature is high in summer, the cooling efficiency of the cooling tower is low, which will affect the heat exchange efficiency of the condenser and limit the cooling of the material. Figure 1 As shown, a separate condenser includes: a cavity 100, an air heat exchange tube 200 and a liquid heat exchange tube 300.

[0025] A material inlet 110 is provided on one side of the cavity 100 in the longitudinal direction, and a material outlet 120 is provided at the bottom of the cavity 100, and the material outlet 120 is provided on the side away from the material inlet 110; a gas phase inlet 130 and a gas phase outlet 140 are provided on the side of the cavity 100 close to the material inlet 110, and the two ends of the gas heat exchange pipe 200 are respectively connected to the gas phase inlet 130 and the gas phase outlet 140; a liquid phase outlet 160 and a liquid phase inlet 150 are provided on the other side of the cavity 100 in the longitudinal direction, and the two ends of the liquid heat exchange pipe 300 are respectively connected to the liquid phase outlet 160 and the liquid phase inlet 150.

[0026] In this embodiment, the high-temperature material is first cooled through the gas heat exchange pipe 200 and then cooled through the liquid heat exchange pipe 300 to reduce the temperature of the circulating water at the liquid phase outlet 160 . More specifically, the high-temperature material enters the cavity 100 through the material inlet 110, and the material inlet 110 is arranged on one side of the length direction of the cavity 100 to increase the reaction time of the material in the cavity 100. After the high-temperature material enters the cavity 100, it is restricted to pass through the air heat exchange pipe 200 for heat exchange. In this process, the material is cooled, and the air in the air heat exchange pipe 200 is heated. The hot gas can be connected to the heating end through the gas phase outlet 140. After the first cooling, the material passes through the area where the liquid heat exchange pipe 300 is provided. The circulating water cooled in the cooling tower passes through the liquid heat exchange pipe 300 and exchanges heat with the material outside the liquid heat exchange pipe 300. After heat exchange, the material is cooled again and discharged to the outside of the cavity 100 through the material outlet 120. The temperature of the circulating water in the liquid heat exchange pipe 300 increases and is discharged to the cooling tower through the liquid phase outlet 160 for cooling.

[0027] The high-temperature material first passes through an independent air heat exchange area. The material passing through this area transfers heat to the air in the air heat exchange pipe 200 in this area. The cold air in the air heat exchange pipe 200 will take away some of the heat and become hot air and be discharged outside the device. This process can not only take away some of the heat in the material, reduce the amount of heat absorbed by the circulating water, and reduce the temperature of the circulating water at the liquid phase outlet 160, thereby reducing the cooling burden of the cooling tower, but also can use the high-temperature gas generated in the air heat exchange pipe 200 as a heat source required for winter heating or pipeline heating. In addition, the separate condenser of the present application separates the gas and the circulating water independently. While the gas takes away the heat, it will not cause volatilization loss of the circulating water, thus achieving the effect of saving water.

[0028] It is worth noting that the high-temperature material of the present application must first pass through the gas heat exchange tube 200 for heat exchange, and then pass through the liquid heat exchange tube 300 to achieve the effect of lowering the circulating water temperature.

[0029] In a possible implementation, the gas phase inlet 130 is disposed at the bottom of the cavity 100 , and the gas phase outlet 140 is disposed at the top of the cavity 100 .

[0030] In one possible implementation, a partition 400 is further included. The partition 400 is disposed between the gas heat exchange tube 200 and the liquid heat exchange tube 300 . A preset distance is provided between the top and bottom of the partition 400 and the inner wall of the cavity 100 .

[0031] In one possible implementation, a through hole is provided on the partition 400 for connecting the gas heat exchange area and the liquid heat exchange area.

[0032] A partition 400 is installed between the gas heat exchange tube 200 and the liquid heat exchange tube 300. This partition 400 blocks material from flowing from a predetermined position into the liquid heat exchange tube 300. A predetermined distance exists between the top and bottom of the partition 400 and the inner wall of the chamber 100, allowing the material to pass through after primary cooling. The partition 400 blocks the transfer of material, reducing its transfer rate and thereby increasing heat exchange time and effectiveness.

[0033] In one possible implementation, the air heat exchange pipe 200 is a straight pipe, coil or spiral pipe, and the liquid heat exchange pipe 300 is a U-shaped pipe, coil or spiral pipe. The forms of the air heat exchange pipe 200 and the liquid heat exchange pipe 300 can be flexibly set according to actual needs.

[0034] In one possible implementation, the liquid phase outlet 160 is disposed on the top of the liquid phase inlet 150 .

[0035] In one possible implementation, baffles 310 are provided between the liquid heat exchange tubes 300 to increase the distribution area of ​​the circulating water in the liquid heat exchange tubes 300 , slow down the flow rate of the circulating water, and enhance the heat exchange effect.

[0036] In one possible implementation, the ratio of the height of the partition 400 to the height of the interior of the cavity 100 is 2:5-4:5, and the height of the partition 400 is greater than the height of the liquid heat exchange tube 300 .

[0037] In one possible implementation, the ratio of the liquid heat exchange tube 300 to the cavity 100 in the length direction is 1:3-1:2. The longer the liquid heat exchange tube 300 is, the better the heat exchange effect is.

[0038] In one possible implementation, a baffle 500 is provided between the bottom of the liquid heat exchange tube 300 and the bottom of the cavity 100, and the material outlet 120 is provided at the bottom of the baffle 500. The baffle 500 can slow down the heat exchange time of the material in the liquid heat exchange tube 300 area, so that it can fully exchange heat.

[0039] It should be noted that although a separate condenser is described above as an example in this application, those skilled in the art will understand that this application should not be limited thereto. In fact, users can flexibly set various parameters according to their personal preferences and / or actual application scenarios, as long as the design is reasonable.

[0040] In this way, when the high-temperature material enters the cavity, it first passes through the air heat exchange pipe near the inlet end of the high-temperature material, and then transfers the heat to the air in the air heat exchange pipe after passing through the air heat exchange pipe. Therefore, the cold air entering the air circulation heat exchange area will take away part of the heat in the material and become hot air, which is discharged through the gas phase outlet. The material after heat exchange through the air heat exchange pipe will then pass through the liquid heat exchange pipe for heat exchange, and the low-temperature material after heat exchange will be discharged through the material outlet. The high-temperature material first passes through the air heat exchange pipe to take away part of the heat, thereby reducing the temperature of the circulating water at the liquid phase outlet and reducing the cooling burden on the cooling tower. The heat taken away can also be used as a heat source for heating or pipeline heating. At the same time, the present application can completely separate the gas and circulating water. While the gas takes away the heat, it will not cause volatilization loss of the circulating water, thus saving water.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
