Technical Field

[0001] The utility model relates to the technical field of evaporative condensers, in particular to a condenser with waste heat recoverable. Background Art

[0002] An evaporative condenser is a heat exchange device composed of a fan, condensing coil, heat exchange fins, a box and other components. The water at the bottom is pumped upward and evenly sprinkled downward, and the external cold air is drawn into the shell through the bottom port area by the fan above the inside and discharged upward to increase the evaporation effect of the scattered water droplets, so as to take away the heat of the condensing coil, and then the hot and humid gas is discharged upward.

[0003] Publication No. CN219776044U discloses an evaporative condenser with waste heat recovery function. The device is provided with a corresponding spiral tube at the air outlet of the condenser, cold water is introduced into the spiral tube, and the hot air discharged from the condenser is used to heat the spiral tube, and then the water passing through the spiral tube is heated to realize the reuse of the waste heat of the condenser. The spiral tube is fixed on a cross-shaped frame, and the frame is installed by a movable clamping plate to adapt to air outlets of different sizes, thereby increasing the overall flexibility and practicality. However, the patent still has the following problems in actual use:

[0004] The device heats the spiral tube by the hot air discharged from the condenser, and then heats the water passing through the spiral tube to realize the reuse of the waste heat of the condenser. However, the hot air of the device heats the cold water inside the spiral tube. When the water inside the spiral tube is heated and turns into water vapor, if the external temperature is low, the tube wall temperature may be lower than the dew point temperature, resulting in water droplets on the outside of the tube. Since the device is not provided with an anti-backflow structure, water droplets may fall into the inside of the condenser, thereby damaging and contaminating the internal parts of the condenser and the circulating water, causing inconvenience to the staff when using it.

[0005] A condenser with waste heat recovery is proposed to solve the above problems. Utility Model Content

However, the hot air of the device heats the cold water inside the spiral tube. When the water inside the spiral tube is heated and becomes water vapor, if the external temperature is low, the tube wall temperature may be lower than the dew point temperature, resulting in water droplets on the outside of the tube. Since the device is not provided with an anti-backflow structure, water droplets may fall into the inside of the condenser, thereby damaging and polluting the internal parts and circulating water of the condenser, causing inconvenience to the staff when using it.

[0007] To achieve the above object, the utility model provides the following technical solution: a waste heat recoverable condenser, comprising a condenser body, an air outlet pipe is installed inside the top of the condenser body, a double-way pipe is installed at the top of the air outlet pipe, a fan is installed inside the air outlet pipe, an anti-backflow mechanism is symmetrically arranged inside the double-way pipe, and heating components are arranged at both ends of the double-way pipe;

[0010] Preferably, an arc-shaped plate is installed inside the top end of the two-way pipe, and the bottom sides of both ends of the arc-shaped plate are in contact with the mounting ring.

[0011] Preferably, sliding sleeves are symmetrically installed at both ends of the push plate, and the interior of the sliding sleeve is slidably connected to a limit rod, and both ends of the limit rod are fixedly connected to the interior of the installation box.

[0012] Preferably, a collection box is symmetrically installed between the air outlet pipe and the two-way pipe, and the top of the collection box is fixedly connected to a water inlet pipe, and the top of the water inlet pipe passes through the two-way pipe and is fixedly connected.

[0016] 1. When the hot air squeezes the block, thereby making the block move away from the mounting ring, the block moves with the moving rod, and the movement of the moving rod drives the slider to slide inside the slide groove. At this time, the first telescopic spring contracts. When water droplets are generated in the double-way pipe and the fan stops running, the first telescopic spring contracts and resets, so that the block can be re-engaged with the inner side of the mounting ring, thereby preventing the water inside the two ends of the double-way pipe from flowing back into the condenser body, thereby greatly reducing the damage to the condenser body, improving the service life of the device, and bringing practicality to the staff when using it. Since the double-way pipe is arranged outside the condenser body, there is still a phenomenon of condensed water droplets when the hot air passes through the double-way pipe. Through the arc design of the arc plate, the condensed water droplets can slide into the interior of the mounting pipe through the arc, thereby further reducing the phenomenon of water droplet reflux, and the design of the arc plate can assist the hot air to blow to the two sets of mounting pipes, making the cold water heating efficiency higher;

[0017] 2. The push plate is moved by pulling the plug rod. At this time, the second telescopic spring contracts. By loosening the plug rod and then using the reset property of the second telescopic spring, the plug rod and the two-way pipe can be engaged and fixed, so that the hollow ring and the water storage pipe can be quickly installed and disassembled, which makes it convenient for subsequent staff to collect hot water generated by waste heat recovery, bringing convenience to the staff when using it. The sliding connection between the sliding sleeve and the limit rod can make the movement of the push plate more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Among them, the backflow prevention mechanism 2 includes a mounting tube 201 symmetrically installed inside the two ends of the double-way tube 102, and a mounting ring 202 is fixedly connected inside one end of the mounting tube 201, and a moving rod 203 is arranged inside the mounting tube 201, and a blocking block 204 is snap-connected to the inner side of the mounting ring 202, and the blocking block 204 is fixedly connected to the moving rod 203, and the inner sides of the mounting tube 201 are symmetrically provided with sliding grooves 205, and sliders 206 are symmetrically installed at both ends of the moving rod 203, and the slider 206 is slidingly connected to the sliding groove 205, and a first telescopic spring 207 is installed between the slider 206 and the inside of the sliding groove 205, so as to prevent the water inside the two ends of the double-way tube 102 from flowing back into the condenser body 1, thereby greatly reducing the damage phenomenon of the condenser body 1, improving the service life of the device, and bringing practicality to the staff when using it. On the outside of the condenser body 1, when the hot air passes through the two-way tube 102, there is still a phenomenon of condensed water droplets. An arc plate 208 is installed inside the top of the two-way tube 102, and the bottom sides of both ends of the arc plate 208 are in contact with the mounting ring 202. Through the arc design of the arc plate 208, the condensed water droplets can slide into the inside of the mounting tube 201 through the arc, thereby further reducing the phenomenon of water droplet reflux, and the design of the arc plate 208 can assist the hot air to blow to the two groups of mounting tubes 201, so that the cold water heating efficiency is higher. A collecting box 209 is symmetrically installed between the outlet pipe 101 and the two-way tube 102, and the top of the collecting box 209 is fixedly connected to the water inlet pipe 210, and the top of the water inlet pipe 210 passes through the two-way tube 102 and is fixedly connected. Through the design of the collecting box 209 and the water inlet pipe 210, the residual water droplets on the inside of the two-way tube 102 can be collected, which brings convenience to the staff when using it.

[0028] The heating component 3 includes a fixing ring 301 which is snap-fitted to both ends of the two-way tube 102, and a snap ring 302 is installed on one side of the fixing ring 301, and the outer side of the snap ring 302 is snap-fitted to the inside of the two-way tube 102, and a hollow ring 303 is fixedly connected to the inside of the fixing ring 301, and water storage pipes 304 are cross-installed between the inner sides of the hollow rings 303, the water storage pipes 304 are communicated with the hollow rings 303, and inlet and outlet pipes 305 are symmetrically installed on one side of the hollow rings 303, and a mounting box 306 is installed inside the fixing ring 301, and a plug rod 307 is slidably connected to the inside of the mounting box 306, and one end of the plug rod 307 is snap-fitted to the two-way tube 102, and a push plate is fixedly connected to the outer side of the plug rod 307. 308, and the outer side of the insertion rod 307 is sleeved with a second telescopic spring 309, through the reset property of the second telescopic spring 309, the insertion rod 307 can be engaged and fixed with the two-way pipe 102, so that the hollow ring 303 and the water storage pipe 304 can be quickly installed and removed, so that it is convenient for subsequent staff to collect the hot water generated by waste heat recovery, which brings convenience to the staff when using it.

[0029] Working principle: Before using this waste heat recovery condenser, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6As shown, when the fan 103 is running, the hot air is discharged through the two ends of the two-way pipe 102, and then the hot air heats the cold water in the water storage pipe 304 and the hollow ring 303. At this time, the hot air squeezes the block 204, so that the block 204 is away from the mounting ring 202. At this time, the block 204 moves with the movement of the moving rod 203, and the movement of the moving rod 203 drives the slider 206 to slide inside the slide groove 205. At this time, the first telescopic spring 207 contracts. When water droplets are generated in the two-way pipe 102 and the fan 103 stops running, the first telescopic spring 207 contracts and resets, so that the block 204 can be re-engaged with the inner side of the mounting ring 202, thereby preventing the water inside the two ends of the two-way pipe 102 from flowing back to the condenser body. 1, thereby greatly reducing the damage phenomenon of the condenser body 1, increasing the service life of the device, and bringing practicality to the staff when using it. Since the two-way pipe 102 is arranged outside the condenser body 1, when the hot air passes through the two-way pipe 102, there is still a phenomenon of condensed water droplets. Through the arc design of the arc plate 208, the condensed water droplets can slide into the inside of the installation pipe 201 through the arc, thereby further reducing the phenomenon of water droplet reflux. The design of the arc plate 208 can assist the hot air to blow to the two groups of installation pipes 201, making the cold water heating efficiency higher. Through the design of the collection box 209 and the water inlet pipe 210, the residual water droplets inside the two-way pipe 102 can be collected, which brings convenience to the staff when using it.

[0030] The cold water is poured into the hollow ring 303 and the water storage tube 304 through the inlet and outlet pipes 305, and then the fixing ring 301 and the clamping ring 302 are engaged with the two ends of the two-way tube 102, and then the push plate 308 is driven to move by pulling the insertion rod 307. At this time, the second telescopic spring 309 contracts, and the insertion rod 307 is loosened, and then the second telescopic spring 309 is reset, so that the insertion rod 307 and the two-way tube 102 can be engaged and fixed, so that the hollow ring 303 and the water storage tube 304 can be quickly installed and disassembled, so that the subsequent staff can collect the hot water generated by waste heat recovery, which brings convenience to the staff when using it, and the sliding connection between the sliding sleeve 310 and the limit rod 311 can make the movement of the push plate 308 more stable.
