Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to a shell-and-tube condenser with a filter cartridge. Background Technology

[0002] The shell-and-tube condenser is installed vertically on a water storage tank. Cooling water enters the pipes from the top distribution tank and flows downwards in a film-like manner along the wall. The flowing water is collected in the water tank below. Refrigerant vapor enters from the top of the shell, releases heat, condenses into liquid outside the tubes, and is discharged from the bottom. Cooling water flows through the tube side (inside the heat transfer tube bundle), while refrigerant flows through the shell side (the space inside the shell and outside the heat transfer tube bundle). That is, high-temperature, high-pressure refrigerant vapor is cooled, condensed, and collected in the shell on the outer surface of the heat transfer tubes.

[0003] Existing shell-and-tube condensers have a relatively simple approach to refrigerant fluid treatment, lacking effective pretreatment. For example, the refrigerant fluid entering the condenser may contain impurities, and without corresponding filtration devices, these impurities will adhere to the surface of the heat exchange tubes over a long period of use, affecting the heat transfer performance of the heat exchange tubes and thus reducing the heat exchange efficiency of the condenser. Utility Model Content

[0004] The purpose of this invention is to provide a shell-and-tube condenser with a filter cartridge. A partition divides the gas storage tank into two cavities. Water vapor flows into tube bundle A, then into tube bundle B through an exchanger tube connected to tube bundle A. Simultaneously, refrigerant is injected into the condenser tubes from the refrigerant inlet pipe. Multiple baffles obstruct the refrigerant, allowing it to pass through the connecting pipe into the interior of filter cartridges A and B. Filter cartridges A and B each contain multiple cavities with filter elements that adsorb impurities in the refrigerant, preventing them from adhering to the heat exchanger tube bundles A and B, thereby improving heat exchange efficiency.

[0005] The present invention adopts the following technical solution: a shell-and-tube condenser with a filter cylinder, comprising a condenser tube, both ends of which are fixedly connected to a flange, a heat exchange tube bundle A and a heat exchange tube bundle B are inserted into one side of the flange, a gas storage chamber is provided at the top of the condenser tube, and an exchange chamber is provided at the lower end of the condenser tube, and a filter cylinder A and a filter cylinder B are provided on the outside of the condenser tube.

[0006] The surface of the gas storage chamber is provided with an air inlet pipe and an air outlet pipe, and a partition is fixedly connected to the inner wall of the gas storage chamber. One end of the partition is fixedly connected to the surface of the flange, and the partition divides the gas storage chamber into two cavities.

[0007] The filter cylinder A and filter cylinder B are provided with multiple sealing plates inside, which divide the filter cylinder A and filter cylinder B into multiple cavities, and each cavity is provided with a filter element.

[0008] The condenser tube is equipped with multiple baffles, which divide the interior of the condenser tube into multiple cavities. Both ends of each cavity are fixedly connected to a connecting pipe, which is connected to the interior of filter cylinder A and filter cylinder B respectively.

[0009] Furthermore, sealing cover plates are fixedly connected to the surfaces of filter cylinder A and filter cylinder B respectively, and the sealing cover plates are connected to the surfaces of filter cylinder A and filter cylinder B by bolts.

[0010] Furthermore, the surface of the baffle plate is provided with tube bundle holes, which are slidably connected to the surfaces of heat exchange tube bundle A and heat exchange tube bundle B.

[0011] Furthermore, a refrigerant inlet pipe and a refrigerant outlet pipe are fixedly connected to the surface of the condenser tube, a support base is fixedly connected to the lower end of the exchange chamber, and a drain pipe is fixedly connected to the surface of the exchange chamber.

[0012] This utility model has the following beneficial effects:

[0013] 1. The gas storage box is divided into two cavities by a partition. Water vapor then flows into tube bundle A and then into tube bundle B through the heat exchange cylinder connected to tube bundle A. At the same time, refrigerant is injected into the condenser tube from the refrigerant inlet pipe. Multiple baffles block the refrigerant, allowing it to enter the interior of filter cylinder A and filter cylinder B through the connecting pipe. Filter cylinder A and filter cylinder B are equipped with filter elements in multiple cavities. The filter elements can adsorb impurities in the refrigerant and prevent impurities from adhering to heat exchange tube bundle A and heat exchange tube bundle B, thereby improving heat exchange efficiency.

[0014] 2. When replacing the filter element, simply loosen the bolts and remove the sealing cover to complete the replacement without disassembling the entire condenser, thus improving work efficiency. The drain pipe at the bottom of the exchange chamber can drain the condensate, ensuring the normal operation of the equipment. Attached Figure Description

Both ends of the condenser tube 1 are fixedly connected to a flange 2. A heat exchange tube bundle A7 and a heat exchange tube bundle B8 are inserted into one side of the flange 2. A gas storage chamber 3 is provided at the top of the condenser tube 1, and an exchange chamber 11 is provided at the lower end of the condenser tube 1. A filter cartridge A14 and a filter cartridge B15 are provided on the outside of the condenser tube 1.

[0024] An air inlet pipe 5 and an air outlet pipe 6 are provided on the surface of the air storage chamber 3, and a partition 4 is fixedly connected to the inner wall of the air storage chamber 3. One end of the partition 4 is fixedly connected to the surface of the flange 2, and the partition 4 divides the air storage chamber 3 into two cavities.

[0025] The filter cartridges A14 and B15 are provided with multiple sealing plates 17 inside, which divide the filter cartridges A14 and B15 into multiple cavities, and each cavity is provided with a filter element 18.

[0026] The condenser tube 1 is provided with multiple baffles 9, which divide the interior of the condenser tube 1 into multiple cavities. Both ends of each cavity are fixedly connected to a connecting pipe 16, which is connected to the interior of the filter cartridge A14 and the filter cartridge B15 respectively.

[0027] Furthermore, sealing cover plates 19 are fixedly connected to the surfaces of filter cartridges A14 and B15 respectively, and the sealing cover plates 19 are connected to the surfaces of filter cartridges A14 and B15 by bolts.

[0028] Furthermore, the surface of the baffle plate 9 is provided with tube bundle holes 10, which are slidably connected to the surfaces of the heat exchange tube bundle A7 and the heat exchange tube bundle B8.

[0029] Furthermore, a refrigerant inlet pipe 12 and a refrigerant outlet pipe 13 are fixedly connected to the surface of the condenser pipe 1, a support base 21 is fixedly connected to the lower end of the exchange chamber 11, and a drain pipe 20 is fixedly connected to the surface of the exchange chamber 11.

[0030] The working principle of this utility model:

[0031] Water vapor flows into the air storage tank from the air inlet. The partition 4 divides the tank into two cavities, allowing water vapor to flow into the heat exchange tube bundle A7. The other end of heat exchange tube bundle A7 is connected to the exchange chamber 11. Water vapor flows into the heat exchange tube bundle B8 through the exchange chamber 11. Then, refrigerant is injected into the condenser tube 1 from the refrigerant inlet pipe 12. Multiple baffles 9 block the refrigerant, allowing it to enter the filter cartridges A14 and B15 through the connecting pipe 16. The filter element 18 installed in the cavity can adsorb impurities in the refrigerant, preventing impurities from adhering to the heat exchange tube bundles A7 and B8, thereby improving heat exchange efficiency. When it is necessary to replace the filter element 18 in the filter cartridges A14 and B15, loosen the bolts and remove the sealing cover plate 19 to replace the filter element 18, thus improving work efficiency. The condensate can be discharged from the exchange chamber 11 through the drain pipe 20 at the lower end of the exchange chamber 11 to ensure the normal operation of the equipment.
