The waste heat is recovered while treating the tail gas.

[0003] In some existing flue gas treatment devices, a simple spraying method is often used to treat flue gas. However, during use, a single spraying method causes some residual particles to rise with the flue gas, and some particles cannot be completely removed, thereby causing pollution to the environment.

[0015] Working principle: First, during use, the first motor drives the first bevel gear to drive the second bevel gear to rotate, and the second bevel gear drives the gas treatment spray rod to rotate when the inner wall of the protective shell rotates. At this time, the gas treatment spray rod rotates on the inner wall of the screw, and the gas treatment spray rod drives the smoke treatment bracket and the smoke treatment atomizing nozzle to rotate on the inner wall of the tank. Water or the treatment liquid used for flue gas treatment is transported to the inside of the gas treatment spray rod through the water tank and sprayed out through the smoke treatment bracket and the smoke treatment atomizing nozzle. During use, harmful gases in the flue gas can be adsorbed and sprayed, and then the flue gas passes through the adsorption plate to achieve the effect of adsorption treatment of the flue gas by the adsorption plate, and during use, it is discharged to the outside through the air outlet duct;

[0016] During use, the worm and the worm wheel are driven to rotate by the second motor on the inner wall of the protective shell, and the screw is driven to rotate on the outer wall of the gas treatment spray rod. The screw rotates inside the protective shell and the upper cover, and the adjusting frame is driven to move up and down by the screw. During use, the adjusting frame slides on the inner wall of the tank body, and the adsorption plate is driven to move downward by the adjusting frame. During use, cleaning liquid or water can be added to the gas treatment spray rod, sprayed through the smoke treatment bracket and the smoke treatment atomizing nozzle, and the adsorption plate is rinsed by water during the downward movement of the adsorption plate. During use, it not only plays the role of spraying harmful exhaust gas, and adsorbing residual exhaust gas through the adsorption plate, but also has the effect of moving the adsorption plate downward through the second motor and the worm when there are too many adsorbed particles on the adsorption plate, and quickly cleaning the adsorption plate through water or cleaning liquid. During use, the degree of automation is high and the structure is simple. During use, the cost is low and the effect of dual treatment of exhaust gas is achieved. When the adsorption effect of the adsorption plate decreases due to the adsorption of too many particles, the adsorption plate has the function of automatic cleaning for use;

[0017] When the adjustment frame slides on the inner wall of the tank body, the tank body plays the role of limiting the upward and downward movement of the adjustment frame. During use, the connecting sleeve allows the flue gas and clean water to flow in and out. During use, the inner partition can prevent the cleaning liquid from contacting the flue gas, which causes resistance when the flue gas rises and the flue gas accumulates inside the connection treatment box. The water flow bridge can allow the water flow to have a separate water flow channel, which is separated from the treatment inlet channel to make a partition treatment. During use, the gas treatment spray rod can further increase the suction force inside the tank body during the self-rotation process, which can increase the flue gas entry speed and prevent the flue gas from being blocked inside the heat recovery base and the inlet and outlet air boxes;

[0018] The inlet and outlet bellows connected to the left and right sides of the treatment box are used for flue gas to pass through during use. When the flue gas enters the inlet and outlet bellows through the smoke inlet channel, the flue gas has a relatively high temperature. At this time, water is injected into the water inlet pipe. When the flue gas contacts the outer wall of the heat conduction pipe, the temperature will be transmitted to the heat conduction pipe through the heat conduction pipe and the heat will be absorbed through the heat conduction pipe. The hot water will be discharged through the water outlet pipe. During use, the heat can be recovered, and the waste of excess energy can be avoided. The flue gas first enters through the heat conduction pipe on the right, and then goes down into the interior of the heat recovery base, and then is discharged into the interior of the connection treatment box through the inlet and outlet bellows on the left. During use, the waste of excess heat in the flue gas can be further avoided, and the high temperature can be avoided from causing damage to the internal structure of the tank. At the same time, harmful impurities in the flue gas and some particles in the flue gas can be first removed through the heat conduction pipe. It is adsorbed and treated. During use, not only can the water containing the treatment liquid be sprayed out through the gas treatment spray rod to adsorb the harmful components in the flue gas, and then discharged to the outside through the adsorption plate and the air outlet duct, which plays the effect of the first treatment, but it can also be sprayed through the smoke treatment bracket and the smoke treatment atomizing nozzle. During use, it can have the effect of automatically cleaning the adsorption plate. At the same time, the residual harmful gas can be adsorbed and finally discharged through the adsorption plate. The heat in the flue gas is adsorbed through the heat conduction pipe, and cold water is sent in through the water inlet pipe, and hot water is output to the outside through the water outlet pipe. During use, the waste of high-temperature flue gas is further avoided, and the effect of recycling heat is achieved. It also passes through the lower surface of the cover plate through the card plate. During use, it can have the effect of quickly installing and disassembling the filter, and can quickly replace the filter.

[0019] The present invention provides a tail gas treatment device and a waste heat recovery system. It has the following beneficial effects:

[0020] 1. In the present invention, flue gas enters the interior of the tank through the bottom cover plate, and water is then sent into the interior of the gas treatment spray rod through the water tank, and the first motor drives the first bevel gear to rotate, driving the second bevel gear and the gas treatment spray rod to rotate inside the protective shell and the screw, and the water containing the treatment liquid is sprayed out through the gas treatment spray rod to adsorb harmful components in the flue gas, and then discharged to the outside through the adsorption plate and the air outlet duct, and the worm and worm gear are driven by the second motor to rotate the screw, and the screw drives the adjustment frame to allow the adsorption plate to move downward under the inner wall limit of the tank. During use, cleaning liquid is added to the interior of the water tank, and can be sprayed through the smoke treatment bracket and the smoke treatment atomizing nozzle, so that the adsorption plate can be automatically cleaned during use, and the residual harmful gas can be adsorbed and finally discharged through the adsorption plate.

[0021] 2. The present invention collects the liquid after spraying through the connecting sleeve, flows into the interior of the connection treatment box through the water bridge and the sewer channel for collection, and filters the particles or other foreign matter remaining in the treatment liquid through the external filter shell, and then recycles it. During use, it reduces the cost of using the cleaning liquid and avoids pollution to the environment. After the flue gas enters the interior of the heat recovery base and the inlet and outlet wind box through the smoke inlet channel, the heat in the flue gas is adsorbed through the heat conduction pipe, and cold water is sent in through the water inlet pipe, and hot water is output to the outside through the water outlet pipe. During use, the waste of high-temperature flue gas is further avoided, and the effect of recovering and using heat is achieved.

[0022] 3. The present invention is interconnected with the heat recovery base through the lower side of the filter shell, and is connected to the processing box through the upper side. The processing box is then connected to the liquid processed inside the heat recovery base for processing, thereby reducing the investment in redundant filtering equipment and further reducing the cost of use. The pressing rod passes through the inner wall of the cover plate and pushes the card plate to drive the spring to be compressed inside the lock shell. During use, the card plate passes through the lower surface of the cover plate, which can achieve the effect of quickly installing and disassembling the filter screen during use, and can quickly replace the filter screen during use.

[0040] Specifically, during use, the first motor 2 drives the first bevel gear 3 to drive the second bevel gear 4 to rotate, and the second bevel gear 4 drives the gas treatment spray rod 5 to rotate when the inner wall of the protective shell 1 rotates. The protrusion of the gas treatment spray rod 5 can be used to slide the gas treatment spray rod 5 on the inner wall of the second bevel gear 4. At the same time, when the gas treatment spray rod 5 slides on the inner wall of the second bevel gear 4, it plays an effect of switching different spray modes.

[0041] Please see attached Figure 2 and attached Figure 7 The outer wall of the adjustment frame 12 is slidably connected to the inner wall of the tank body 16, the inner wall of the tank body 16 is provided with a limit groove, the outer wall of the adjustment frame 12 is slidably connected to the inside of the limit groove, the outer wall of the adsorption plate 13 is slidably connected to the outer wall of the air outlet duct 17, and the outer wall of the water tank 14 is fixedly connected to the inner wall of the protective shell 1. The bottom end of the tank body 16 is fixedly connected with a connecting sleeve 23, and the inner wall of the connecting sleeve 23 is fixedly connected with an inner partition 24. The inner wall of the inner partition 24 is fixedly connected with a water bridge 25, and the outer wall of the water bridge 25 is fixedly connected with a water channel 26, and the inner wall of the inner partition 24 is provided with a processing inlet channel 27.

[0042] Specifically, when the adjusting frame 12 slides on the inner wall of the tank body 16, the tank body 16 has the effect of limiting the upward and downward movement of the adjusting frame 12. During use, the connecting sleeve 23 can allow the flue gas and clean water to flow in and out. During use, the inner partition 24 can prevent the cleaning liquid from contacting the flue gas, resulting in resistance when the flue gas rises, causing the flue gas to accumulate inside the connection treatment box 28.

[0043] Please see attached Figure 4 and attached Figure 5The switching component includes a hydraulic cylinder 39, the output end of the hydraulic cylinder 39 is fixedly connected to a rotating sleeve 45, the outer wall of the gas treatment spray rod 5 is rotatably connected to the inner wall of the rotating sleeve 45, a smoke treatment inner tube 41 is provided inside the gas treatment spray rod 5, a cleaning treatment inner tube 42 is provided inside the gas treatment spray rod 5, a spray water inlet 40 is provided inside the water tank 14, the opening of the smoke treatment inner tube 41 is arranged inside the smoke treatment bracket 6, a cleaning bracket 43 is provided inside the gas treatment spray rod 5, the opening of the cleaning treatment inner tube 42 is arranged inside the cleaning bracket 43, water storage cavities are provided inside the smoke treatment bracket 6 and the cleaning bracket 43, a cleaning DC nozzle 44 is provided inside the cleaning bracket 43, the inner cavity of the smoke treatment atomizing nozzle 7 is connected to the water storage cavity of the smoke treatment bracket 6, and the inner cavity of the cleaning DC nozzle 44 is connected to the water storage cavity of the cleaning bracket 43.

[0044] Specifically, during use, the hydraulic cylinder 39 drives the rotating sleeve 45 to drive the gas treatment spray rod 5 to move up and down. During use, the gas treatment spray rod 5 rotates inside the rotating sleeve 45, and the rotating sleeve 45 plays a limiting effect on the gas treatment spray rod 5, and plays a fixing effect on the gas treatment spray rod 5. The upper part of the gas treatment spray rod 5 is provided with a circular limiting block for the rotation of the gas treatment spray rod 5. During use, this circular limiting block is used to lift the gas treatment spray rod 5 and is also used to fix the gas treatment spray rod 5. The gas treatment spray rod 5 is limited, and the cleaning agent or water for treating the tail gas is sent into the gas treatment spray rod 5 through the spray water inlet 40 inside the water tank 14. During use, the annular connecting sleeve of the water tank 14 is provided with a cavity inside for storing water. When the gas treatment spray rod 5 moves up and down, through the annular connecting sleeve of the water tank 14, when the cleaning treatment inner tube 42 is connected with the spray water inlet 40, the gas treatment spray rod 5 rotates, and the liquid inside the cavity enters the cleaning treatment inner tube 42 and is output as direct current water, which is applied to the adsorption plate 13. Flushing is performed to clean the tank body 16 and the adsorption plate 13. When the hydraulic cylinder 39 drives the rotating sleeve 45 and the gas treatment spray rod 5 to rise, the cleaning treatment inner tube 42 is inserted into the interior of the annular sleeve, and the cleaning treatment inner tube 42 is blocked by the inner wall of the annular sleeve. During use, the cleaning treatment inner tube 42 and the smoke treatment inner tube 41 are sealed. The water pressure will flow into the inner wall of the cleaning treatment inner tube 42 or the smoke treatment inner tube 41 through the cavity. The cleaning treatment inner tube 42 and the smoke treatment inner tube 41 are output ports, and no water leakage will occur during use. During use, the smoke treatment bracket 6 and the smoke treatment atomizing nozzle 7 have the effect of atomizing spraying. During use, the residue in the exhaust gas can be atomized and sprayed, and better contact can be made with the particles in the exhaust gas to improve the treatment effect. During use, the cleaning bracket 43 and the cleaning DC nozzle 44 can have the effect of DC water spraying. During use, the DC water can better flush and clean the adsorption plate 13 and the inner wall of the tank body 16.

[0045] Please see attached Figure 7 -Attached Figure 8, a waste heat recovery system for exhaust gas treatment, including a connection treatment box 28, the inner wall of the connection treatment box 28 is fixedly connected to the outer wall of the connection sleeve 23, the outer walls of both sides of the connection treatment box 28 are fixedly connected with inlet and outlet wind boxes 19, and the inner wall of the left inlet and outlet wind box 19 is fixedly connected with a water outlet pipe 21. The inner wall of the right inlet and outlet wind box 19 is fixedly connected with a water inlet pipe 20, the inner wall of the right inlet and outlet wind box 19 is fixedly connected with a smoke inlet channel 22, the lower surface of the water outlet pipe 21 is fixedly connected with a heat recovery base 18, the heat recovery base 18 and the inner wall of the inlet and outlet wind box 19 are fixedly connected with a heat conduction pipe 29, the outer wall of the heat conduction pipe 29 is S-shaped and fixedly connected to the inside of the heat recovery base 18 and the inlet and outlet wind box 19, the front end of the heat conduction pipe 29 is fixedly connected to the inner wall of the water outlet pipe 21, and the tail end of the heat conduction pipe 29 is fixedly connected to the inner wall of the water inlet pipe 20.

[0046] Specifically, the inlet and outlet wind boxes 19 connected to the left and right sides of the processing box 28 are used for flue gas to pass through during use. When the flue gas enters the inlet and outlet wind boxes 19 through the smoke inlet channel 22, the flue gas has a relatively high temperature. At this time, water is injected into the water inlet pipe 20. When the flue gas contacts the outer wall of the heat-conducting pipe 29, the temperature will be transmitted to the heat-conducting pipe 29 through the heat-conducting pipe 29 and the heat will be absorbed by the heat-conducting pipe 29. The hot water will be discharged through the water outlet pipe 21. During use, the heat can be recovered, and the waste of excess energy can be avoided during use. The flue gas first enters through the heat-conducting pipe 29 on the right, and then enters the interior of the heat recovery base 18 downward, and then passes through the inlet and outlet wind boxes on the left. 19 is discharged into the interior of the connection treatment box 28. The heat-conducting pipe 29 enables it to carry out effective adsorption treatment operations on various harmful impurities and some tiny particles carried in the flue gas. When the flue gas continuously flows through the heat-conducting pipe 29, the cold water inside it will produce a condensation reaction with the heat of the exhaust gas. Due to the condensation of water vapor generated by the contact between the cooling water inside the water pipe and the high-temperature air outside, the harmful impurities mixed in the flue gas, the chemical particles that pollute the environment, and some tiny particles that may affect the stability of the subsequent equipment operation are accurately adsorbed on the inner wall of the pipe. In this way, the preliminary purification treatment of the flue gas is achieved, so that the subsequent flue gas discharge or further treatment process can be carried out in a relatively safer way. In order to carry out the operation in a pure gas environment, the potential interference of impurities accumulated inside the equipment to the operation of the equipment is reduced. The heat-conducting pipe 29 is made of copper, which can have better thermal conductivity during use, so that it can make full use of the contact opportunity with the flue gas and efficiently adsorb and capture the large amount of heat contained in the flue gas. During the continuous operation of the equipment, the continuously generated high-temperature flue gas carries abundant thermal energy. When they flow through the heat-conducting pipe 29, the heat will be rapidly and continuously conducted to the inside of the pipe through the wall of the heat-conducting pipe 29 in the form of heat conduction. Through the water inlet pipe 20, a steady stream of cold water will be accurately and stably delivered to a specific heat exchange area closely connected to the heat-conducting pipe 29. In this area, the cold water and the flue gas that has absorbed a large amount of heat will be absorbed by the flue gas. The heat transfer pipe 29 with a large amount of heat conduction pipes 29 performs a full and detailed heat exchange process. Since heat always follows the natural law of transfer from a high-temperature object to a low-temperature object, during the heat exchange process, the heat adsorbed inside the heat conduction pipe 29 will be quickly and massively transferred to the cold water, causing the temperature of the cold water to gradually increase. As the heat exchange continues, the heated hot water will be orderly and smoothly output along the water outlet pipe 21, which can not only further effectively avoid the waste of excess heat in the flue gas, but also effectively recycle and reuse the heat energy that may have been lost in the air and convert it into a hot water resource that can be actually used, and can also fundamentally prevent the high-temperature flue gas from causing various damages to the internal structure of the tank body 16, such as deformation and degradation of material properties.This is effective in ensuring the normal operation of the equipment, extending the service life of the equipment, and achieving efficient use of energy.

[0047] Please see attached Fig. 9 -Attached Fig.12 A filter shell 30 is fixedly connected to the front inner walls of the heat recovery base 18 and the inlet and outlet wind box 19, and a water pump is arranged inside the rear side of the filter shell 30. The water pump is used to pump water inside the inlet and outlet wind box 19 and the heat recovery base 18 into the filter shell 30. A lock shell 31 is fixedly connected to the outer wall of the filter shell 30, and a cover plate 32 is slidably connected to the upper surface of the lock shell 31 and the filter shell 30, and a handle 33 is fixedly connected to the upper surface of the cover plate 32. The inner wall of the lock shell 31 is slidably connected with a pressing rod 34, the inner wall of the filter shell 30 is provided with a mounting groove 36, the inner wall of the filter shell 30 is slidably connected with a filter screen 35, the outer wall of the filter screen 35 is slidably connected to the inner wall of the mounting groove 36, the outer wall of the pressing rod 34 is slidably connected to the inner wall of the cover plate 32, the right outer wall of the cover plate 32 is slidably connected with a clamping plate 37, the outer wall of the pressing rod 34 is fixedly connected to the inner wall of the clamping plate 37, the rear outer wall of the clamping plate 37 is fixedly connected with a spring 38, and the outer wall of the spring 38 is fixedly connected to the inner wall of the lock shell 31.

[0048] Specifically, sewage or treated water can be pumped into the filter shell 30 for filtering through a water pump, thereby preventing smoke from flowing out through the filter shell 30 during use. The treated smoke treatment liquid, smoke residues adsorbed by the heat transfer pipe 29, and other foreign matter during treatment can be filtered through the filter shell 30 during use. The filter screen 35 is driven to be inserted into the lock shell 31 and the filter shell 30 through the cover plate 32. At this time, the installation groove 36 inside the filter shell 30 plays a limiting and sealing effect during the insertion of the filter screen 35. During use, not only can the insertion of the filter screen 35 be more stable and smoother, but the edges and corners around the filter screen 35 can also be sealed to prevent unfiltered liquid or solution from flowing out from the side, resulting in poor filtering effect. During the process, the pressing rod 34 is pressed to pass through the lower surface of the cover plate 32, and the pressing rod 34 drives the card plate 37 to compress the spring 38 on the inner wall of the lock shell 31, and slides out from the inner wall of the cover plate 32 through the card plate 37, so that the cover plate 32 can be released during use. When the card plate 37 is loosened during use, the cover plate 32 is driven by the handle 33 to realize the design of quick installation and disassembly of the filter 35, so that the replacement of the filter 35 can be completed quickly and accurately. Since the filter 35 can be replaced and adjusted conveniently and quickly, when any problem occurs with the filter 35, it can be dealt with in time without spending too much time and energy on disassembly and assembly of the equipment, which greatly reduces the difficulty and workload of equipment maintenance, so that the entire equipment can always maintain a good operating state during long-term use.
