Abstract
Description
Technical Field
[0001] This utility model relates to the field of condenser technology, and in particular to a multi-stage condenser for chemical production. Background Technology
[0002] Condensers are widely used in the chemical industry and are one of the main heat exchange devices. Currently, traditional condensers mostly use water cooling for heat exchange, where gaseous materials dissipate heat through convection with the water flow, achieving the purpose of condensing and liquefying the materials for recovery.
[0003] However, the water pipes that transport water inside existing condensers usually surround the condensation area, resulting in limited contact area, small heat dissipation area, long condensation time, and high production energy consumption. Utility Model Content
[0004] Therefore, the purpose of this utility model is to propose a multi-stage condenser for chemical production, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0005] To achieve the above objectives, one embodiment of this utility model provides a multi-stage condenser for chemical production, including a condenser tank. The condenser tank has two interlocking partitions inside, and the condenser tank has three cavities separated by the two partitions. Two of the cavities have annularly wound coils inside, one end of which is connected to a liquid inlet via a high-pressure connector, and the other end is connected to a liquid outlet via an expansion valve. All three cavities are connected to a water inlet for supplying water and a water outlet for draining water.
[0006] Preferably, the bottom of the condenser tank is provided with a fixed leg to support it, and a sealing ring is fixedly installed at one end of the condenser tank to seal it.
[0007] The above technical solution involves installing the condenser tank at the location where condensation is required using fixed legs. This allows material to be transported into the condenser tank, while simultaneously supplying condensing water to the inside of the condenser tank for material condensation. A sealing ring is used to seal the entire condenser tank, ensuring the internal structure of the condenser tank is secure.
[0008] Preferably, in any of the above embodiments, the two partitions are divided into an inner partition and an outer partition, which are distributed in a cross pattern. The inner partition and the outer partition are fixed to different sides inside the condenser tank, and there is a gap between the side of the inner partition and the outer partition away from the fixed surface of the condenser tank and the inner wall of the condenser tank.
[0009] Preferably, in any of the above embodiments, the cavities on both sides of the outer partition are connected, and the cavity inside the inner partition is connected to the cavity on both sides of the outer partition.
[0010] The above technical solution divides the internal space of the condenser tank into three cavities using inner and outer partitions. Water for condensation can be injected into the three cavities, allowing the injected condensate water to flow along the partitions of the inner and outer partitions. This maximizes the flow of condensate water within the condenser tank, prolonging the time the condensate water remains inside the condenser tank, increasing the heat transfer time during condensation, and improving the condensation effect.
[0011] Preferably, in any of the above embodiments, the coil is wrapped around the surface of the outer and inner partitions along the outside of the condenser tank and is distributed on both sides of the outer partition.
[0012] Preferably, in any of the above embodiments, the liquid inlet is located on the outside of the outer partition, the liquid outlet is located on the inside of the outer partition, and both the liquid inlet and the liquid outlet are installed through the condenser tank.
[0013] The above technical solution involves introducing the material to be condensed into the inside of the coil through the liquid inlet, allowing the material to flow along the coil from the outside to the inside of the condenser tank, and finally to the liquid outlet for discharge. The coil's encircling structure extends the material flow time and improves the condensation effect.
[0014] Preferably, in any of the above embodiments, the cavity on the outer side of the outer partition is connected to an inlet that penetrates the condenser tank, the cavity on the inner side of the outer partition and the cavity inside the inner partition are connected to an outlet that penetrates the condenser tank, and the outlet connected to the cavity inside the inner partition is connected to the inlet through a circulation pipe.
[0015] The above technical solution allows water to be injected into the condenser tank through the inlet. The water flows through the cavity along the space structure created by the outer and inner partitions. After condensation and heating, the water flows out from two outlets. The water flowing from the outlet on the outer side of the inner partition has a shorter flow path and a higher temperature, requiring it to be returned to the cooling equipment for further cooling before being introduced into the inlet for use. Conversely, the water flowing from the outlet on the inner side of the inner partition has a longer flow path and a lower temperature, allowing it to be directly returned to the inlet for recycling via a circulation pipe, thus saving water.
[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0017] 1. Multiple cooling cavities are opened inside the condenser tank, and annular coils are installed inside the cavities to condense and transport materials. The multi-layered design of the coils allows for better contact with the condensate inside the cavities, increasing the heat dissipation area inside the condenser and effectively improving the condensation effect. The interconnected design of the inlet and outlet of multiple cavities enables multi-stage condensation of circulating water, reducing energy consumption. At the same time, the small-diameter high-pressure connector and expansion valve increase the material flow rate, reducing the pressure and temperature of the material on the inner wall of the coils and improving the condenser efficiency.
[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
[0019] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:
[0020] Figure 1 This is a cross-sectional structural diagram according to an embodiment of the present utility model;
[0021] Wherein: 1-condenser tank, 2-partition, 21-inner partition, 22-outer partition, 3-cavity, 4-coil, 5-liquid inlet, 6-liquid outlet, 7-water inlet, 8-water outlet. Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0023] like Figure 1 As shown in the figure, a multi-stage condenser for chemical production according to an embodiment of the present invention includes a condenser tank 1. The condenser tank 1 has two interlocking partitions 2 inside. The condenser tank 1 has three cavities 3 separated by the two partitions 2. The two cavities 3 are equipped with annular coils 4. One end of the coil 4 is connected to a liquid inlet 5 through a high-pressure connector, and the other end is connected to a liquid outlet 6 through an expansion valve. All three cavities 3 are connected to a water inlet 7 for supplying water and a water outlet 8 for draining water.
[0024] Preferably, the bottom of the condenser tank 1 is provided with a fixed leg to support it, and a sealing ring is fixedly installed at one end of the condenser tank 1 to seal it.
[0025] The above technical solution is adopted: the condenser tank 1 is installed in the position where condensation is required by fixing legs. The material is transported into the condenser tank 1, and condensing water is transported into the condenser tank 1 to condense the material. The condenser tank 1 is sealed as a whole by sealing ring to ensure the internal condition of the condenser tank 1.
[0026] Preferably, in any of the above schemes, the two partitions 2 are divided into an inner partition 21 and an outer partition 22, which are distributed in a cross pattern. The inner partition 21 and the outer partition 22 are fixed to different sides inside the condenser tank 1, and there is a gap between the side of the inner partition 21 and the outer partition 22 away from the fixed surface of the condenser tank 1 and the inner wall of the condenser tank 1.
[0027] Preferably, in any of the above schemes, the cavities 3 on both sides of the outer partition 22 are connected, and the cavity 3 inside the inner partition 21 is connected to the cavity 3 on both sides of the outer partition 22.
[0028] The above technical solution divides the internal space of the condenser tank 1 into three cavities 3 by the inner baffle 21 and the outer baffle 22. Water for condensation can be injected into the three cavities, and the injected condensing water flows along the isolation of the space by the outer baffle 22 and the inner baffle 21. This allows the condensing water to flow to the maximum extent inside the condenser tank 1, prolongs the time that the condensing water stays inside the condenser tank 1, increases the heat conduction time during the condensation process, and improves the condensation effect.
[0029] Preferably, in any of the above schemes, the coil 4 is wrapped around the outer side of the condenser tank 1 and attached to the surface of the outer partition 22 and the inner partition 21, with the coil 4 distributed on both sides of the outer partition 22.
[0030] Preferably, in any of the above schemes, the liquid inlet 5 is located on the outside of the outer partition 22, and the liquid outlet 6 is located on the inside of the outer partition 22. Both the liquid inlet 5 and the liquid outlet 6 are installed through the condenser tank 1.
[0031] The above technical solution is adopted: the material to be condensed is introduced into the inside of the coil 4 through the liquid inlet 5, so that the material flows from the outside to the inside of the condenser tank 1 along the coil 4, and finally flows to the liquid outlet 6 for discharge. The surrounding structure of the coil 4 can extend the material flow time and improve the material condensation effect.
[0032] Preferably, in any of the above embodiments, the cavity 3 on the outer side of the outer partition 22 is connected to the inlet 7 that penetrates the condenser tank 1, the cavity 3 on the inner side of the outer partition 22 and the cavity 3 inside the inner partition 21 are connected to the outlet 8 that penetrates the condenser tank 1, and the outlet 8 connected to the cavity 3 inside the inner partition 21 is connected to the inlet 7 through a circulation pipe.
[0033] Using the above technical solution: Water that needs to be condensed can be injected into the interior of the condenser tank 1 from the inlet 7. The water flows from the inlet 7 into the cavity along the spatial structure formed by the outer baffle 22 and the inner baffle 21. Finally, the condensed and heated water flows out from the two outlets 8. The water flowing out from the outlet 8 on the outer side of the inner baffle 21 has a shorter flow path and a higher temperature. It needs to be guided back to the cooling equipment to be cooled again before it can be introduced into the inlet 7 for use. The water flowing out from the outlet 8 on the inner side of the inner baffle 21 has a longer flow path and a lower temperature. It can be directly guided back to the inlet 7 for recycling through the circulation pipe, which can save water.
[0034] The working principle of this utility model for a multi-stage condenser used in chemical production is as follows:
[0035] Connect the liquid inlet 5 to the material feeding device and the liquid outlet 6 to the material recovery device. After the material is fed into the coil 4 through the liquid inlet 5, cold water is fed into the condenser tank 1 through the water inlet 7 to condense the material inside the coil 4.
[0036] Compared with the prior art, the present invention has the following advantages:
[0037] 1. Multiple cooling cavities 3 are opened inside the condenser tank 1, and annular coils 4 are installed inside the cavities 3 to condense and transport materials. The multi-layered design of the coils 4 allows for better contact with the condensate inside the cavities 3, increasing the heat dissipation area inside the condenser and effectively improving the condensation effect. The interconnected design of the inlet and outlet of the multiple cavities 3 enables multi-stage condensation of circulating water, reducing energy consumption. At the same time, the small-diameter high-pressure connector and expansion valve increase the material flow rate, reducing the pressure and temperature of the material on the inner wall of the coil and improving the condenser efficiency.
