Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to an energy-saving condensation device for difluorochloromethane. Background Technology

[0002] Dichlorofluoromethane is a colorless gas at room temperature with a slightly sweet odor. It has high chemical stability and is mainly used as a refrigerant. It is widely used in household air conditioners, commercial refrigeration equipment, and heat pump systems. In the refrigeration cycle, dichlorofluoromethane needs to release latent heat through a phase change from gaseous to liquid state. The condenser uses cooling water or air to force it to cool down and liquefy, thus completing the heat transfer.

[0003] A difluorochloroethane energy-saving condensing device, application number CN202022610194.0, includes a first condenser comprising a shell, end caps, an exhaust pipe, a pressure gauge, an inlet pipe, a coolant inlet, a coolant outlet, and an outlet pipe. A second condenser is fixedly installed on one side of the bottom of the first condenser, and the inlet pipe of the second condenser is connected to the outlet pipe of the first condenser via a pipe. A first water tank is fixedly installed on one side of the first condenser, comprising a tank body, an inlet, an outlet, and a return port. A second water tank is fixedly installed on one side of the second condenser, and a detector is fixedly installed on one side of the bottom of the second condenser. This difluorochloroethane energy-saving condensing device has a simple and reasonable structure, is easy to use, and effectively solves the problems of complex structure, high cost, lack of monitoring devices, and waste of water resources in most existing difluorochloroethane energy-saving condensing devices, thus possessing high practical value. However, when condensate is recycled, hard components such as calcium and magnesium ions in the water are prone to forming scale at high temperatures. The water may also carry particulate matter, microorganisms, or chemical precipitates, which can lead to blockage of condenser pipes over a long period of time, thereby reducing heat exchange efficiency and even causing equipment failure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an energy-saving condensation device for difluorochloromethane.

[0005] An embodiment of this utility model provides an energy-saving condensation device for difluorochloromethane, comprising:

[0006] A frame is provided, on which a first condenser and a second condenser are fixedly mounted and connected by a connecting pipe. Two water storage tanks are fixedly connected to both frames, respectively mounted on the first and second condensers. Filter assemblies are installed on both water storage tanks, and a stirring assembly is installed between the two tanks. Each filter assembly includes a mounting bracket that slides through the water storage tank, on which a filter screen is fixedly mounted. A fixed shell is fixedly mounted on the side wall of the water storage tank, and multiple springs are fixedly connected to the inner wall of the fixed shell. A connecting plate is fixedly connected between the springs, and the connecting plate is slidably connected within the fixed shell. A locking block is fixedly connected to the connecting plate, and a locking groove is formed on the mounting bracket, with the locking block matching the groove. A pull rod slides through the fixed shell and is fixedly connected to the connecting plate.

[0007] Furthermore, the stirring assembly includes two rotating rods rotatably connected to the inner wall of the water storage tank. Multiple stirring rods are fixedly connected to each of the two rotating rods. Sprockets are rotatably connected to the side walls of the two water storage tanks. The two sprockets are respectively fixedly connected to the two rotating rods. The two sprockets are driven by a chain. A first motor is fixedly installed on one of the side walls of the water storage tank. The rotating end of the first motor is fixedly connected to one of the rotating rods.

[0008] Furthermore, a pull ring is fixedly connected to the pull rod, the pull ring is provided with an anti-slip pad layer, and the locking block is wedge-shaped.

[0009] Furthermore, the water storage tank is connected to an injection pipe, a feed pipe, and a discharge pipe. A valve is installed on the discharge pipe. Each of the two water storage tanks is connected to a set of delivery pipes. The two sets of delivery pipes are respectively connected to the first condenser and the second condenser. The delivery pipes are grouped in pairs, and a water pump is installed on the delivery pipes.

[0010] Furthermore, each of the two mounting brackets is fixedly connected to a handle, and each of the two mounting brackets has a sealing gasket layer on its side wall.

[0011] Furthermore, multiple pads are fixedly connected to the lower end face of the frame, and each of the multiple pads is provided with anti-slip texture.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. After the condensate is collected into the storage tank, it will be filtered through the filter screen to remove any particulate matter, microorganisms or chemical precipitates that may be carried in the condensate, prevent condenser pipe blockage, ensure heat exchange efficiency, and avoid equipment failure. In addition, the mounting bracket is fixed by the use of clips and slots, which makes it easy for users to install and remove the mounting bracket, improving the portability of the device.

[0014] 2. Scale inhibitor is added into the water storage tank through the injection pipe. Then, the first motor drives one of the rotating rods to rotate. Under the transmission of the chain and sprocket, the rotating rod rotates and the stirring rod stirs and mixes the scale inhibitor and condensate, thereby interfering with the crystallization and deposition process of inorganic salts in the water, preventing scale from forming on the equipment surface, thereby improving heat exchange efficiency and extending the equipment life.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4 As shown in the figure, this utility model embodiment proposes an energy-saving condensation device for difluorochloromethane, comprising:

[0022] The frame 1 has multiple pads fixedly connected to its lower end face. Each pad has anti-slip texture to improve the stability of the device. The first condenser 2 and the second condenser 3 are fixedly installed on the frame 1. The first condenser 2 and the second condenser 3 are both existing technologies and are usually composed of a shell, cooling water tube bundle, tube sheet, end cap, support frame and connecting pipes. The heat is transferred quickly through high-efficiency heat-conducting materials and reasonable flow channel design. After the high temperature and high pressure dichlorofluoromethane vapor enters the condenser, it exchanges heat with the cooling water flowing through the condenser tube or shell. The flow of water carries away the latent heat of vaporization and sensible heat released by the refrigerant, causing the temperature of dichlorofluoromethane to drop below the saturation temperature and finally condense into a liquid state. The details will not be elaborated here. The first condenser 2 and the second condenser 3 are connected by a connecting pipe. A water storage tank 4 is fixedly connected to both frames 1.

[0023] Two water storage tanks 4 are respectively installed on the first condenser 2 and the second condenser 3. Each water storage tank 4 is equipped with a filter assembly, and a stirring assembly is installed between the two water storage tanks 4. The filter assembly includes a mounting bracket 5 that slides through the water storage tank 4, on which a filter screen 6 is fixedly installed. A fixed shell 7 is fixedly installed on the side wall of the water storage tank 4. Multiple springs 8 are fixedly connected to the inner wall of the fixed shell 7, and a connecting plate is fixedly connected between the multiple springs 8. The connecting plate is slidably connected inside the fixed shell 7, and a [missing information - likely a specific component or element] is fixedly connected to the connecting plate. The mounting bracket 5 has a slot for the locking block 9, which matches the slot. A pull rod slides through the fixed shell 7 and is fixedly connected to the connecting plate. A pull ring 15 is fixedly connected to the pull rod and has an anti-slip pad to facilitate the user's pulling of the pull rod, thus improving the portability of the device. The locking block 9 is wedge-shaped. Both mounting brackets 5 have handles fixedly connected to them, which facilitates the user's removal of the mounting brackets 5 and improves the portability of the device. Both mounting brackets 5 have sealing pads on their side walls, which improves the sealing between the mounting brackets 5 and the water tank 4.

[0024] The stirring assembly includes two rotating rods 10 rotatably connected to the inner wall of the water storage tank 4. Multiple stirring rods 11 are fixedly connected to each of the two rotating rods 10. Sprockets 12 are rotatably connected to the side walls of both water storage tanks 4, and the two sprockets 12 are respectively fixedly connected to the two rotating rods 10. The two sprockets 12 are driven by a chain 13. A first motor 14 is fixedly installed on the side wall of one of the water storage tanks 4, and the rotating end of the first motor 14 is fixedly connected to one of the rotating rods 10. A liquid injection pipe 16, a material injection pipe, and a discharge pipe are connected to the water storage tank 4. A valve is installed on the discharge pipe. A set of delivery pipes is connected to each of the two water storage tanks 4, and the two sets of delivery pipes are respectively connected to the first condenser 2 and the second condenser 3. The infusion tubing is arranged in pairs, and a water pump is installed on the tubing. The water pump is a current technology. The working principle of the water pump is based on centrifugal force and energy conversion. The drive device drives the pump shaft to rotate the impeller at high speed. The impeller blades push the liquid as it rotates, generating centrifugal force, which causes the liquid to be thrown from the center of the impeller to the outer edge, thus increasing its kinetic energy. After the liquid enters the pump casing, the volute structure with the gradually expanding flow channel converts part of the kinetic energy into static pressure energy. The pressurized liquid is discharged through the outlet pipe. Two of the water pumps can pump the water in the first condenser 2 and the second condenser 3 into the two water storage tanks 4 respectively. The other two water pumps can send the water from the two water storage tanks 4 into the first condenser 2 and the second condenser 3 respectively. This will not be described in detail here.

[0025] The detailed working process of this utility model is as follows:

[0026] Dichlorofluoromethane is introduced into the first condenser 2. The first condenser 2 and the second condenser 3 work together, using water to condense the dichlorofluoromethane. Indirect heat exchange between the cooling water and the high-temperature gaseous dichlorofluoromethane causes the gaseous dichlorofluoromethane to release latent heat under high pressure and change phase to liquid before being discharged. The condensate from the first condenser 2 and the second condenser 3 is pumped to the storage tank 4 by a water pump. The condensate is then filtered through the filter screen 6 to remove any particulate matter, microorganisms, or chemical precipitates that may be carried in the condensate, preventing blockage of the pipes in the first condenser 2 and the second condenser 3, ensuring heat exchange efficiency, and avoiding equipment failure. The user adds scale inhibitor to the storage tank 4 through the injection pipe. Subsequently, the first motor 14 drives one of the rotating rods 10 to rotate, and the chain 13 and chain... Driven by the wheel 12, the rotating rod 10 rotates, and the stirring rod 11 stirs and mixes the scale inhibitor and condensate, thereby interfering with the crystallization and deposition process of inorganic salts in the water, preventing scale buildup on the equipment surface, thus improving heat exchange efficiency and extending equipment life. After long-term use, the user can pull the pull ring 15 to remove the locking block 9 from the slot, allowing the mounting bracket 5 to be pulled out for easy cleaning and maintenance of the filter screen 6. After cleaning, the user inserts the mounting bracket 5 into the water storage tank 4. The side wall of the mounting bracket 5 will contact the locking block 9, which will be pushed and temporarily moved into the fixed shell 7. When the locking block 9 is aligned with the slot, the spring 8 automatically resets, and the locking block 9 automatically moves into the slot, thus limiting and fixing the mounting bracket 5. This facilitates the user's installation and removal of the mounting bracket 5, improving the portability of the device.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
