Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a circulating condenser for an activated carbon adsorption device. Background Technology

[0002] In the process of waste gas treatment and purification, activated carbon adsorption and condensers are sometimes used in conjunction. Condensation separates condensable substances (such as water vapor and volatile organic compounds) from the gas, reducing the load on the activated carbon and improving its adsorption efficiency. The condenser lowers the gas temperature, causing condensable substances to condense into a liquid state, thus effectively separating and removing them. However, in existing condensers, water enters from one end and flows directly out from the other in a straight line. During this process, the contact time between the gas and the heat exchange tubes is short, resulting in low condensation heat exchange efficiency and an inability to effectively condense the gas discharged from the activated carbon adsorption device. Utility Model Content

[0003] The purpose of this invention is to provide a circulating condenser for an activated carbon adsorption device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a circulating condenser for an activated carbon adsorption device, comprising:

[0005] The cylinder has an air outlet pipe and an air inlet pipe at both ends of the top of the cylinder.

[0006] A heat exchange tube is placed inside the cylinder, and a partition plate is provided on the outside of the heat exchange tube to divide the inside of the cylinder into S-channels.

[0007] A collection pipe is placed at the bottom of the cylinder to collect condensate.

[0008] The cold water chamber is located at one end of the cylinder away from the water distribution chamber. A refrigeration unit is provided on one side of the cold water chamber. The refrigeration unit includes an evaporator tube placed inside the cold water chamber and a condenser placed inside the cylinder. The condenser corresponds to the air inlet pipe and is used to remove heat from the outside of the condenser by condensing gas.

[0009] Preferably, a plurality of collection pipes are fixedly connected to the bottom of the cylinder, and a connecting pipe is fixedly connected to the bottom of the collection pipe at an angle, with a liquid collection tank fixedly connected to one end of the connecting pipe.

[0010] Preferably, a water distribution chamber is fixedly connected to one end of the cylinder, and a water baffle is fixedly connected to the middle of the water distribution chamber.

[0011] Preferably, the water distribution chamber is internally fixed with two baffles to divide the water distribution chamber into an inlet chamber and an outlet chamber. The heat exchange tube is installed at the corresponding positions of the inlet chamber and the outlet chamber. An inlet pipe is fixedly connected to the top of the inlet chamber, and an outlet pipe is fixedly connected to the bottom of the outlet chamber.

[0012] Preferably, the outer side of the partition plate is fitted to the inner wall of the cylinder, and multiple partition plates are provided and arranged alternately in top and bottom.

[0013] Preferably, the refrigeration unit further includes a compressor fixed to the outside of the cylinder, the condenser is connected to the compressor, and the compressor is connected to the evaporator through an expansion valve.

[0014] Compared with existing technologies, the advantages of this invention are as follows: By setting up two sets of heat exchange tubes with upper inlet and lower outlet, and by using a partition plate to divide the inside of the cylinder into an S-shaped channel, the gas flows along an S-shaped path inside the cylinder, increasing the contact time and contact area between the gas and the heat exchange tubes, thereby improving the condensation heat exchange efficiency and enabling more effective condensation treatment of the gas discharged from the activated carbon adsorption device; cold water enters the upper heat exchange tube from the inlet pipe, is cooled by the cold water chamber, enters the lower heat exchange tube, and is then discharged from the outlet pipe, forming a circulation to ensure that the cooling water continuously and effectively cools the gas, thus achieving refrigeration. The unit includes an evaporator, a condenser, and a compressor. Through a refrigeration cycle, the water inside the cold water chamber is further cooled. The cooled water then comes into contact with the gas again in the lower heat exchange tubes, further enhancing the cooling capacity of the condenser and ensuring that the gas can be fully condensed. The condenser tube is located inside the cylinder and is positioned between two sets of heat exchange tubes, corresponding to the gas outlet pipe. When the gas is discharged through the gas outlet pipe, the air can carry away the heat from the outside of the condenser tube. At the same time, the heat from the condenser tube can dry the condensed air, improving the quality of the discharged gas and reducing the impact of water vapor on subsequent equipment or the environment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a circulating condenser for an activated carbon adsorption device, comprising: a cylindrical body 1, with an outlet pipe 2 and an inlet pipe 3 fixedly connected to both ends of the top of the cylindrical body 1; two sets of heat exchange tubes 14 fixedly connected to the inside of the cylindrical body 1 by a support plate, the heat exchange tubes 14 being arranged in two sets arranged vertically, the two sets of heat exchange tubes 14 being used for water inlet and water outlet respectively, and a partition plate 15 being provided on the outside of the heat exchange tubes 14 to divide the inside of the cylindrical body 1 into S-channels; a collection pipe 8 being placed at the bottom of the cylindrical body 1 to collect condensed liquid; a cold water chamber 10 being fixedly connected to the end of the cylindrical body 1 away from the water distribution chamber 6 to connect the two sets of heat exchange tubes 14; a refrigeration section being provided on one side of the cold water chamber 10, the refrigeration section including an evaporator pipe 12 placed inside the cold water chamber 10 and a condenser 13 placed inside the cylindrical body 1, the condenser 13 corresponding to the inlet pipe 3, and used to remove heat from the outside of the condenser 13 by condensing gas.

[0024] It should be noted that in this embodiment, the exhaust pipe 2 is located at one end of the cold water inlet. The exhaust port of the fan guiding the gas is connected to the intake pipe 3, and the cold water source delivery pipe is connected to the water inlet of the heat exchange pipe 14. The gas enters the cylinder 1 through the intake pipe 3. Under the action of the partition plate 15, the gas travels along the S-shaped channel inside the cylinder 1. During the travel, it comes into contact with the heat exchange pipe 14 for heat exchange, thereby achieving condensation. After the water comes into contact with the air in the heat exchange pipe 14, it enters the cold water chamber 10. Under the action of the evaporator pipe 12 of the refrigeration section, the water inside the cold water chamber 10 is cooled, and the cooled water moves towards the other end of the cylinder 1 in the lower heat exchange pipe 14. During this period, the gas comes into contact with it to achieve heat exchange. The gas after heat exchange and condensation is discharged upward through the exhaust pipe 2. Since the condenser pipe 13 is uniquely located at the exhaust pipe 2, the air carries the gas outside the condenser pipe 13 out of the exhaust pipe 2. The heat of the condenser pipe 13 can dry the condensed air.

[0025] In one embodiment, a plurality of collection pipes 8 are fixedly connected to the bottom of the cylinder 1, and a connecting pipe is fixedly connected to the bottom of the collection pipe 8 at an angle, with a liquid collection tank 9 fixedly connected to one end of the connecting pipe.

[0026] It should be noted that in this embodiment, the condensed liquid enters the connecting pipe through the collecting pipe 8, and then enters the liquid collection tank 9 through the connecting pipe. The bottom of the liquid collection tank 9 is fixed with a drain port and a corresponding valve, so as to facilitate opening the valve for sewage discharge.

[0027] In one embodiment, a water distribution chamber 6 is fixedly connected to one end of the cylinder 1, a water baffle 7 is fixedly connected to the middle of the water distribution chamber 6, and two water baffles 7 are fixedly connected inside the water distribution chamber 6 to divide the water distribution chamber 6 into an inlet chamber and an outlet chamber. The heat exchange tube 14 is installed at the corresponding positions of the inlet chamber and the outlet chamber. An inlet pipe 4 is fixedly connected to the top of the inlet chamber, and an outlet pipe 5 is fixedly connected to the bottom of the outlet chamber.

[0028] It should be noted that in this embodiment, the water baffle 7 divides the water distribution chamber 6 into two chambers. The inlet pipe 4 and the outlet pipe 5 are connected to the two chambers respectively. Cold water enters the heat exchange pipe 14 located in the upper group from the inlet pipe 4, then enters the cold water chamber 10 and then enters the heat exchange pipe 14 located in the lower group. Then it is discharged through the outlet pipe 5. The discharged water enters the chiller and is pumped back into the inlet pipe 4.

[0029] In one embodiment, the outer side of the partition plate 15 is attached to the inner wall of the cylinder 1, and multiple partition plates 15 are provided and arranged alternately in the upper and lower positions.

[0030] It should be noted that in this embodiment, the partition plate 15 divides the internal distribution of the cylinder 1, so that the space moves along an S-shaped path inside the cylinder 1, thereby increasing the contact time between the heat exchange tube 14 and the air, so that it can be fully heat exchanged. The water in the cold water chamber 10 that has been cooled moves in the opposite direction to the air flow direction, so that it can be contacted with the air again for cooling.

[0031] In one embodiment, the refrigeration unit further includes a compressor 11 fixed to the outside of the cylinder 1, a condenser pipe 13 connected to the compressor 11, and the compressor 11 connected to the evaporator pipe 12 via an expansion valve.

[0032] It should be noted that in this embodiment, the condenser 13 is connected to the compressor 11, which compresses and discharges the gaseous refrigerant. The compressor 11 introduces the refrigerant into the evaporator 12 through the expansion valve, which regulates the flow rate and pressure of the refrigerant. The evaporator 12 absorbs heat, causing the refrigerant to change from a liquid to a gaseous state during evaporation. The condenser 13 is located inside the cylinder 1 and between two sets of heat exchange tubes 14, and it can dry the condensed air.
