Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and in particular relates to a waste gas treatment device for the reuse of high-temperature waste gas. Background Technology

[0002] Some factories generate a large amount of high-temperature gas during production operations. If the gas is directly discharged into the air, it will waste the high-temperature energy in the gas. Generally, cold water is used to replace the heat in the high-temperature exhaust gas. However, these high-temperature gases usually contain solid particles such as dust particles. During the replacement process, the solid particles in the high-temperature gas will fall into the replacement device under the influence of gravity and other factors. If they are not cleaned for a long time, it will cause the internal space of the device to decrease and the weight of the device to increase, resulting in the device failing to work properly.

[0003] As disclosed in patent application number CN202321312523.0, a waste gas treatment device for high-temperature waste gas reuse includes a water storage tank, an inlet pipe, an outlet pipe, a purification component, a fixing device, a high-temperature waste gas utilization mechanism, and a displacement structure. The water storage tank has an inlet pipe at its top and an outlet pipe at its bottom. Valves are installed on the surfaces of both the inlet and outlet pipes. The purification component is connected to the side of the water storage tank, and a fixing device is installed on its surface. The high-temperature waste gas utilization mechanism is connected to the water storage tank. A displacement structure is located at the bottom of the water storage tank. This invention, through the cooperation of the water storage tank, inlet pipe, outlet pipe, purification component, and fixing device, enables the purification component to filter and treat high-temperature waste gas, thereby preventing harmful substances from being emitted into the environment and causing pollution.

[0004] In existing technologies, the purification components, such as water tanks, inlet pipes, outlet pipes, purification components, and fixing devices, work together to filter high-temperature exhaust gases. However, there are still shortcomings. First, most high-temperature exhaust gases contain solid particles, especially exhaust gases from metal smelting plants. When these gases are replaced by water in the pipes, the solid particles fall into the high-temperature gas pipes. The curved and enclosed pipes are not easy to clean, but if they are not cleaned regularly, it will affect the normal operation of the device.

[0005] Furthermore, existing devices cannot efficiently exchange heat from high-temperature exhaust gas into cold water because the heat levels of the exhaust gas at the inlet and outlet are different, resulting in low utilization of heat from the high-temperature exhaust gas. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this invention provides a waste gas treatment device for the reuse of high-temperature waste gas. This invention utilizes a second support rod, an elastic telescopic rod, and a vibrator. The output of the vibrator drives the waste gas collection box and water pipe to vibrate, causing accumulated solid particles on the inner wall of the waste gas collection box and the outer wall of the water pipe to fall into the waste discharge pipe, achieving a cleaning effect inside the waste gas collection box. With the air inlet and water inlet located at the same end of the waste gas collection box, the significant temperature difference between cold water and high-temperature air allows for faster heat absorption, thus maximizing the absorption of heat from the high-temperature waste gas and improving its utilization rate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device for high-temperature waste gas reuse, comprising a base plate, a waste gas filter box disposed on the base plate, multiple filter plates disposed inside the waste gas filter box, a waste gas collection box slidably disposed above the base plate, an air inlet disposed on the upper end face of the waste gas collection box, an air outlet disposed on the bottom side wall of the waste gas collection box, a water inlet disposed on one side of the air inlet on the side wall of the waste gas collection box, a water outlet disposed on one side of the air outlet on the side wall of the waste gas collection box, a water pipe disposed between the water inlet and the water outlet inside the cavity of the waste gas collection box, multiple vibrators disposed on the waste gas collection box, a waste discharge pipe disposed at the bottom of the waste gas collection box, and a sealing plate slidably disposed on the waste discharge pipe.

[0008] Optionally, the exhaust gas collection box is provided with a first clamp, and a second clamp is provided on the outside of the first clamp. Multiple second support rods are rotatably provided on both the upper and lower end faces of the second clamp, and multiple elastic telescopic rods are rotatably provided between one side of each second support rod and the first clamp.

[0009] Optionally, multiple springs are provided between the first clamp and the second clamp.

[0010] Optionally, each of the second support rods is rotatably equipped with a roller at the end that abuts against the side wall of the exhaust gas collection box.

[0011] Optionally, a plurality of support blocks are provided on the end face of the base plate, and a first support rod is rotatably provided between each support block and the second clamp.

[0012] Optionally, a waste collection frame is slidably provided on the lower end face of the waste discharge pipe.

[0013] Optionally, the lower end face of the waste discharge pipe is provided with two grooves, and a protrusion is slidably disposed in each groove. One end of the protrusion is fixedly connected to the upper end face of the waste collection frame.

[0014] Optionally, a handle is provided on one side of the waste collection box.

[0015] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0016] (1) This utility model sets up a second support rod, an elastic telescopic rod, and a vibrator, etc. The output end of the vibrator drives the waste gas collection box and the water pipe to vibrate, so that the solid particles accumulated on the inner wall of the waste gas collection box cavity and the outer wall of the water pipe can fall into the waste discharge pipe, achieving the effect of cleaning the inside of the waste gas collection box cavity. While the vibrator vibrates and cleans the waste gas collection box and other components, the cooperation between the second support rod and the elastic telescopic rod and other components can absorb the vibration generated by the output end of the vibrator driving the waste gas collection box, thereby improving the stability and durability of the device.

[0017] (2) The present invention has an air inlet and a water inlet set at the same end of the exhaust gas collection box. Since the high temperature of the exhaust gas entering through the air inlet is the highest, the temperature at the top of the exhaust gas collection box is higher than that at the bottom. The water inlet is located at the top of the exhaust gas collection box, and cold water continuously enters through the water inlet. Since the temperature difference between the cold water and the high temperature air is large, the water absorbs heat faster, thereby absorbing more heat from the high temperature exhaust gas and improving the utilization rate of heat in the high temperature exhaust gas.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, 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.

[0027] Example 1:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a waste gas treatment device for high-temperature waste gas reuse includes a base plate 10, a waste gas filter box 32 disposed on the base plate 10, a plurality of filter plates 33 disposed inside the waste gas filter box 32, a waste gas collection box 11 slidably disposed above the base plate 10, an air inlet 20 disposed on the upper end face of the waste gas collection box 11, an air outlet 21 disposed on the bottom side wall of the waste gas collection box 11, a water inlet 22 disposed on one side of the air inlet 20 on the side wall of the waste gas collection box 11, and a water outlet 23 disposed on one side of the air outlet 21 on the side wall of the waste gas collection box 11, with the water inlet 22 and the water outlet 23 located between the cavity of the waste gas collection box 11. The body is equipped with a water pipe 24. The exhaust gas collection box 11 is equipped with a first clamp 12. The first clamp 12 is equipped with a second clamp 13 on the outside. Multiple second support rods 16 are rotatably installed on the upper and lower end faces of the second clamp 13. Multiple elastic telescopic rods 17 are installed between one side of each second support rod 16 and the first clamp 12. Both ends of each elastic telescopic rod 17 are rotatably connected to the first clamp 12 and the second support rod 16. Multiple vibrators 19 are installed on the exhaust gas collection box 11. The bottom of the exhaust gas collection box 11 is equipped with a waste discharge pipe 27. A sealing plate 28 is slidably installed on the waste discharge pipe 27.

[0029] Specifically, both the air inlet 20 and the water inlet 22 are located at the upper end of the exhaust gas collection box 11. Since the high-temperature exhaust gas entering through the air inlet 20 has the highest temperature, the temperature at the top of the exhaust gas collection box 11 is higher than the temperature at the bottom. The water inlet 22 is located at the upper end of the exhaust gas collection box 11, and cold water continuously enters through it. Due to the large temperature difference between the cold water and the high-temperature air, the water absorbs heat faster. Since the heat at the top of the exhaust gas collection box 11 is the highest, the heat absorption rate of the high-temperature exhaust gas is the highest, resulting in a higher heat absorption rate of the device. Furthermore, the water pipe 24 is spirally arranged, which allows for a longer water pipe 24 to be accommodated within the same size exhaust gas collection box 11 cavity, thus displacing more heat from the high-temperature exhaust gas and improving the utilization rate of heat in the high-temperature exhaust gas.

[0030] Vibrator 19 is a common vibrator, which is existing technology and will not be elaborated on in this solution. The vibration of vibrator 19 can drive the exhaust gas collection box 11 to vibrate, thereby allowing the solid impurities in the high-temperature exhaust gas adhering to the inner wall of the exhaust gas collection box 11 to detach from the inner wall of the exhaust gas collection box 11, thus achieving the removal of solid particles adhering to the inner wall.

[0031] The elastic telescopic rod 17 is a common elastic telescopic rod, which is existing technology and will not be elaborated on in this solution. The exhaust gas collection box 11 is stretched and fixed by multiple elastic telescopic rods 17 and a second support rod 16 arranged between the first clamp 12 and the second clamp 13. When the multiple vibrators 19 on the exhaust gas collection box 11 are working, the multiple vibrators 19 will drive the exhaust gas collection box 11 to vibrate. The second support rod 16 and the second clamp 13 are rotatably connected. Multiple elastic telescopic rods 17 are rotatably arranged between the second support rod 16 and the first clamp 12. Therefore, the vibration generated by the vibrator 19 driving the exhaust gas collection box 11 can be absorbed by the multiple elastic telescopic rods 17, thereby keeping the exhaust gas collection box 11 stably fixed inside the second clamp 13. Moreover, the vibration of the exhaust gas collection box 11 driven by the vibrator 19 will not affect the stability and robustness of the entire device.

[0032] The sealing plate 28 that slides on the waste discharge pipe 27 can seal the waste discharge pipe 27, so that the high-temperature waste gas inside the waste gas collection box 11 will not leak out through the waste discharge pipe 27.

[0033] Furthermore, such as Figure 5 and Figure 6 As shown, a waste collection frame 29 is slidably provided on the lower end face of the waste discharge pipe 27. Two grooves 31 are provided on the lower end face of the waste discharge pipe 27. A protrusion 30 is slidably provided in each groove 31. One end of the protrusion 30 is fixedly connected to the upper end face of the waste collection frame 29. A handle 26 is provided on one side of the waste collection frame 29.

[0034] Specifically, the waste collection box 29 is slidable, which facilitates the disassembly of the waste collection box 29, making it easy to clean up in a timely manner when the waste collection box 29 is full of solid particulate waste, and the handle 26 makes it more convenient to assemble and disassemble the waste collection box 29.

[0035] The protrusion 30 and the groove 31 are slidably arranged to improve the sealing performance of the connection between the waste collection frame 29 and the waste discharge pipe 27.

[0036] Furthermore, such as Figure 5 As shown, multiple springs 18 are provided between the first clamp 12 and the second clamp 13.

[0037] Specifically, the spring 18 can absorb the vibration generated by the vibrator 19 driving the exhaust gas collection box 11, thereby improving the overall stability of the device.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, a plurality of support blocks 15 are provided on the end face of the base plate 10. Each support block 15 is provided with a first support rod 14 between it and the second clamp 13. The two ends of the first support rod 14 are rotatably connected to the side of the first clamp 12 and the end face of the support block 15, respectively.

[0039] Specifically, the first support rod 14 is rotatably connected to the side of the first clamp 12 and the end face of the support block 15, which can reduce the vibration transmitted to the base plate 10 along the first support rod 14 when the vibrator 19 drives the exhaust gas collection box 11 to vibrate, thereby improving the overall stability of the device.

[0040] Furthermore, such as Figure 2 and Figure 7 As shown, each of the second support rods 16 has a roller 25 rotatably mounted on the end that abuts against the side wall of the exhaust gas collection box 11.

[0041] Specifically, the roller 25 reduces the friction between the end of the second support rod 16 that contacts the side wall of the exhaust gas collection box 11 and the side wall of the exhaust gas collection box 11, thereby improving the durability of the device.

[0042] First, high-temperature exhaust gas is transported to the cavity of exhaust gas collection box 11 through air inlet 20. At the same time, cold water is transported to water pipe 24 through water inlet 22. The high-temperature gas inside exhaust gas collection box 11 will displace the cold water in water pipe 24 through the pipe wall of water pipe 24, thereby enabling the heat in high-temperature exhaust gas to be recovered and utilized.

[0043] During the above process, since high-temperature exhaust gas often contains a large number of solid particles and other impurities, these will accumulate on the inner wall of the exhaust gas collection box 11 and the outer wall of the water pipe 24 over a long period of time. Multiple vibrators 19 are activated, and the output end of the vibrators 19 drives the exhaust gas collection box 11 to vibrate. The exhaust gas collection box 11 drives the water pipe 24 to vibrate, thereby causing the solid matter accumulated on the inner wall of the exhaust gas collection box 11 and the outer wall of the water pipe 24 to fall into the waste discharge pipe 27 and then into the waste collection frame 29. If too much impurity accumulates inside the waste collection frame 29 and needs to be cleaned, the sealing plate 28 is closed to cut off the connection between the waste discharge pipe 27 and the waste collection frame 29. After the waste collection frame 29 is cleaned, the waste collection frame 29 is slid into the bottom of the waste discharge pipe 27, and then the sealing plate 28 is moved to open the connection channel between the waste discharge pipe 27 and the waste collection frame 29.
