[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, an industrial waste gas waste heat recovery device includes a base plate 1, a treatment tank 2 installed on the top of the base plate 1, a treatment component 4 installed inside the treatment tank 2, the treatment component 4 including a swirl plate 404 fixedly connected inside the treatment tank 2, an installation frame 401 slidably inserted inside the treatment tank 2, the swirl plate 404 being located at the top of the installation frame 401, two installation slots 402 being provided inside the installation frame 401, one of the installation slots 402 being located inside the treatment tank 2, a filter screen 403 being installed inside each of the two installation slots 402, a water collection pipe 3 being fixedly installed inside the treatment tank 2, a plurality of atomizing nozzles being provided at the bottom of the water collection pipe 3 being distributed at equal intervals, a water inlet pipe being installed at the top of the water collection pipe 3, and the water inlet pipe penetrating the treatment tank 2 and extending outward.

A drive frame 408 is threadedly connected to the lead screw 406. Two horizontally set limit rods 407 are fixedly connected inside the support frame 405. The drive frame 408 is slidably sleeved on the outside of the two limit rods 407. A motor 409 is fixedly installed on one side of the outer wall of the support frame 405. The output end of the motor 409 is coaxially fixed with one end of the lead screw 406.

[0026] Exhaust gas enters the treatment tank 2 through the side inlet and then passes through the internal channel of the swirl plate 404. Guided by the blades of the swirl plate 404, the exhaust gas rotates. Combined with the atomized droplets sprayed from the water collection pipe 3, impurities in the exhaust gas are captured by the droplets and then adhere to the inner wall of the treatment tank 2 under centrifugal force. Under gravity, the gas then flows downwards and finally falls into the filter screen 403 installed inside the mounting slot 402. Impurities are intercepted by the filter screen 403, while water flows through the filter holes and falls to the bottom of the treatment tank 2. During this process, the droplets also recover some heat.

[0027] After a period of use, the new filter screen 403 is installed in the mounting slot 402 outside the treatment tank 2. The motor 409 outside the support frame 405 is started. The motor 409 drives the lead screw 406 to rotate. The lead screw 406 drives the drive frame 408 to move closer to the treatment tank 2 along the two limit rods 407. The drive frame 408 pushes the mounting frame 401 to move synchronously. The new filter screen 403 enters the interior of the treatment tank 2. The filter screen 403 containing impurities moves to the outside, ensuring that the device can be put into use more quickly and that the impurities have sufficient time to be cleaned.

[0028] like Figure 1 and Figure 3 As shown, a recycling component 5 is installed on the top of the base plate 1. The recycling component 5 includes an exhaust pipe 501 fixedly installed outside the exhaust port of the processing tank 2. Several diversion pipes 502 are fixedly inserted into one end of the exhaust pipe 501. Several diversion pipes 503 are provided at one end of the bottom of each of the several diversion pipes 502. A thin tube 504 is fixedly inserted into the end of each of the several diversion pipes 503. The several thin tubes 504 are fixedly connected to the same connecting chamber 505.

[0029] A recycling tank 506 is fixedly installed on the top outer wall of the base plate 1. Several thin tubes 504 are fixedly inserted into the inside of the recycling tank 506. An installation port is provided on the top and bottom outer walls of the recycling tank 506.

[0030] The exhaust gas flows through the outlet at the top of the treatment tank 2 into the exhaust pipe 501, then into several diversion pipes 502, and then into several diversion pipes 503. After that, it enters several fine pipes 504. The exhaust gas is divided into several small streams, which can ensure that the heat in the exhaust gas can be absorbed more thoroughly by the water in 506. The water can be poured in from the opening at the bottom of the recovery tank 506 and then come out from the opening at the top, ensuring that the heat can be effectively absorbed.

[0031] like Figure 1 and Figure 2 As shown, a sealing ring is provided inside each of the external mounting holes of the treatment tank 2, which can improve the sealing effect between the treatment tank 2 and the mounting frame 401.

[0032] like Figure 1 and Figure 2 As shown, the installation groove 402 is cone-shaped. Under the flushing of water, impurities will flow down the slope of the installation groove 402, thus ensuring that the filtration effect of the upper part of the filter screen 403 can always be maintained.

Guided by the blades of the swirl plate 404, the exhaust gas rotates. Combined with the atomized droplets sprayed from the water collection pipe 3, impurities in the exhaust gas are captured by the droplets. Under centrifugal force, these droplets adhere to the inner wall of the treatment tank 2, and then flow downwards under gravity, finally falling into the filter screen 403 installed inside the mounting groove 402. The impurities are intercepted by the filter screen 403, while the water flows through the filter holes to the bottom of the treatment tank 2. During this process, the droplets... It can also recover some heat. After a period of use, the new filter 403 is installed in the mounting slot 402 outside the treatment tank 2. The motor 409 outside the support frame 405 is started. The motor 409 drives the lead screw 406 to rotate. The lead screw 406 drives the drive frame 408 to approach the treatment tank 2 along the two limit rods 407. The drive frame 408 pushes the mounting frame 401 to move synchronously. The new filter 403 enters the interior of the treatment tank 2. The filter 403 containing impurities moves to the outside, ensuring that the device can be put into use more quickly and that the impurities have enough time to be cleaned.

[0036] The exhaust gas flows through the outlet at the top of the treatment tank 2 into the exhaust pipe 501, then into several diversion pipes 502, and then into several diversion pipes 503. After that, it enters several fine pipes 504. The exhaust gas is divided into several small streams, which can ensure that the heat in the exhaust gas can be absorbed more thoroughly by the water in 506. The water can be poured in from the opening at the bottom of the recovery tank 506 and then come out from the opening at the top, ensuring that the heat can be effectively absorbed.
