Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a high-temperature waste gas treatment device for a factory. Background Art

[0002] During the industrial production process, high-temperature gases are generated. These gases are also called factory high-temperature exhaust gases. These exhaust gases contain a large amount of harmful substances, such as particulate matter, acidic gases, nitrogen oxides, volatile organic compounds, etc. These harmful substances cause serious harm to the environment and human health.

[0003] Before exhaust gas is discharged, the waste residue contained in the exhaust gas must be separated and treated first. At present, the commonly used equipment is to use filter plates to filter the exhaust gas. However, as the waste residue is continuously intercepted and accumulated on the filter screen of the filter plate, the filter screen will be blocked. At this time, the filter plate must be removed and the waste residue on the filter screen must be cleaned to avoid seriously affecting the normal production of industrial equipment. The removal of the filter plate will affect the treatment of the exhaust gas.

[0004] In actual applications, the upper filter plate is responsible for filtering a large amount of debris in the flue gas, which is easy to clog; while the lower filter plate is specifically used to filter tiny particles remaining in the flue gas, so it requires more delicate cleaning. Vibration cleaning is suitable for situations with weak adhesion and more particles, and can quickly remove debris from the upper filter plate, while brush cleaning is suitable for more delicate cleaning. However, due to the differences in pollutants and filter plate characteristics, a single cleaning method cannot meet all needs.

[0005] The technical solution of an environmentally friendly exhaust gas treatment device is disclosed in a Chinese patent with publication number CN107824012A. In the technical solution of the environmentally friendly exhaust gas treatment device, an air bag is used to expand the particles floating on the water surface, and at the same time, the second air bag is inflated to change the pressure in the delivery pipe, thereby forcing the pressure valve to open and causing the exhaust gas to be ejected from the through hole. The device can effectively control the amount of exhaust gas entering the cold water and prevent particles on the water surface from hindering the discharge of the purified exhaust gas. However, the patent still has many defects.

[0006] For example, when the conveying pipe is full of exhaust gas, the exhaust gas fan needs to be turned off to keep the exhaust gas in a fixed amount in the conveying pipe. After a long period of purification, the exhaust gas fan is started again. During the period when the exhaust gas fan is turned off, the exhaust gas cannot enter the conveying pipe. The entire exhaust gas filtration process is discontinuous, and frequent motor starting and stopping will accelerate the wear of the motor and increase energy consumption. In addition, an additional control system is required to coordinate the starting and stopping of the motor, which increases the complexity of the system. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-Figure 9 The present invention provides a factory high-temperature exhaust gas treatment device, including a box body 10, which is cylindrical. The interior of the box body 10 is divided into an inner cavity and an outer cavity by an annular plate 11, and the inner cavity is divided into a cooling chamber and an air suction chamber by an inner partition plate 12, and the outer cavity is divided into a solid filtration chamber and an adsorption chamber by an outer partition plate 13.

[0045] There is water at a lower temperature in the cooling chamber. When the high-temperature exhaust gas enters the box 10, its heat will be transferred to the low-temperature water, thereby reducing the temperature of the high-temperature exhaust gas. In this process, the high-temperature exhaust gas and the low-temperature water exchange heat through the annular plate 11. The low-temperature water serves as a medium and will produce water-insoluble precipitates such as calcium carbonate and magnesium carbonate after being heated. As time goes by, these precipitates will gradually adhere to the container wall or the inner wall of the pipe to form scale. Suction will be generated in the suction chamber, and this suction will suck the high-temperature exhaust gas entering the box 10 into the suction chamber.

[0046] The solid filter chamber is mainly used to capture solid particles in high-temperature exhaust gas to prevent it from causing air pollution and endangering human health. After the solid particles are filtered, the exhaust gas enters the adsorption chamber. The adsorption chamber uses adsorption to treat the exhaust gas. The adsorption chamber contains water, and the exhaust gas is mixed with water for purification to further reduce the exhaust gas temperature. During the adsorption process, floating particles will float on the water surface, and the adsorbed exhaust gas will continue to be discharged upward. However, in the prior art, the adsorbed exhaust gas cannot continue to be treated because the floating particles block the water surface, resulting in poor adsorption effect.

[0047] A motor 14 and an air intake device 20 driven by the motor 14 are provided on the top of the box body 10. The motor 14 provides power for the exhaust gas treatment device. Driven by the motor 14, the air intake device 20 draws external normal temperature air into the box body 10. The normal temperature air contacts the high-temperature exhaust gas that has just entered the box body 10, and the auxiliary cooling chamber can quickly reduce the temperature of the exhaust gas.

[0048] A driving rod 15 is fixed to the bottom of the motor 14, and the driving rod 15 extends to the bottom of the inner cavity of the box body 10. The motor 14 can rotate the driving rod 15; a scale cleaning device 30 driven by the driving rod 15 is installed in the cooling chamber, and the scale cleaning device 30 can clean the scale in the cooling chamber. An induced draft fan blade 16 sleeved on the outer ring of the driving rod 15 is installed in the air intake chamber. The induced draft fan blade 16 rotates driven by the driving rod 15 to suck the exhaust gas in the solid filter chamber into the air intake chamber.

[0049] A first filter plate 40 and a second filter plate 50 are provided in the solid filter chamber. The first filter plate 40 is driven by the scale cleaning device 30, and the second filter plate 50 is driven by the first filter plate 40. The first filter plate 40 and the second filter plate 50 can be driven to perform vibration cleaning and brush cleaning respectively. Vibration cleaning is highly efficient and can quickly remove most of the impurity particles, thereby saving manpower and material resources. Brush cleaning can effectively remove tiny particles in the holes to ensure filtering accuracy. It is particularly suitable for filter plates with smaller pore sizes. For filter plates with different pore sizes, corresponding cleaning methods are adopted to give full play to the advantages of the two methods to achieve better cleaning effects.

[0050] The bottom of the driving rod 15 is connected to a transmission structure 60, which is installed on the bottom wall of the inner cavity of the box body 10. An exhaust structure 70 and a push plate 80 are installed in the adsorption chamber, and both the exhaust structure 70 and the push plate 80 are driven by the transmission structure 60. The exhaust gas in the suction chamber is introduced into the adsorption chamber under the driving action of the exhaust structure 70. At the same time, the push plate 80 can reciprocate under the driving of the transmission structure 60, so that waves are formed on the water surface in the adsorption chamber, and the particles floating on the water surface are pushed apart, so that the purified exhaust gas can be more easily discharged from the box body 10.

[0051] Furthermore, the air inlet device 20 includes an air inlet pipe 21 embedded in the top of the box body 10, and dustproof nets 22 are provided at both ends of the air inlet pipe 21 to effectively block pollutants such as dust and particulate matter in the external air from entering the box body 10. This can prevent these impurities from mixing with high-temperature exhaust gas to cause corrosion or blockage to the device, thereby extending the service life of the device.

[0052] In addition, an air intake fan 23 is also installed in the inner cavity of the air intake pipe 21, which is connected to the motor 14 through a belt. The rotation of the air intake fan 23 can drive the normal temperature air outside the device into the box 10, so that the normal temperature air comes into contact with the high-temperature exhaust gas that has just entered the box 10, thereby reducing the temperature of the exhaust gas and reducing the load of the subsequent cooling equipment.

[0053] In addition, a one-way valve or a non-return valve may be installed in the air inlet device 20. These valves only allow air to flow in one direction, that is, from the outside into the inside of the box body 10, to prevent exhaust gas from flowing back.

[0054] Furthermore, the scale cleaning device 30 includes a driving ring 31, the outer ring of which is fixed with a first ring gear 32, the first ring gear 32 is connected to the inner wall of the cooling chamber and can rotate, the driving ring 31 is fixedly sleeved on the outer ring of the driving rod 15, and the scale cleaning rods 34 are fixed on the upper and lower sides of the driving ring 31.

[0055] During operation, the movement of the drive rod 15 drives the drive ring 31 to rotate, thereby driving the scale cleaning rod 34 to rotate. The scale cleaning rod 34 continuously rubs against the inner wall of the cooling chamber to effectively remove stubborn scale, thereby shortening the downtime for maintenance and improving equipment utilization.

[0056] Furthermore, the first filter plate 40 includes a conical filter sleeve 41, the inner ring of which is fixed a second annular gear 42, the second annular gear 42 is connected to the solid filter chamber and is rotatable, and a collecting box 90 is fixed to the inner wall of the solid filter chamber.

[0057] The surface of the conical filter sleeve 41 is inlaid with a fine filter mesh 43, which can effectively intercept tiny solid particles to ensure the filtering effect. A waste cleaning rod 44 is provided on the top of the fine filter mesh 43, and both ends of the waste cleaning rod 44 are fixedly connected to the inner wall of the solid filter chamber.

[0058] The first annular gear 32 and the second annular gear 42 are threadedly connected to the double-headed gear 33 that passes through the annular plate 11. When the driving ring 31 rotates, the driving ring 31 drives the double-headed gear 33 to rotate through the first annular gear 32, and the double-headed gear 33 then drives the second annular gear 42 to rotate. Since the debris cleaning rod 44 is fixed on the inner wall of the solid filter chamber, the rotation of the conical filter sleeve 41 will allow the bristles of the debris cleaning rod 44 to continuously brush the fine filter mesh 43. The debris cleaning rod 44 can continuously clean the surface of the fine filter mesh 43 to ensure that it always remains clean, thereby maintaining a high filtration efficiency.

[0059] Furthermore, the second filter plate 50 includes a spring 51 and an annular shell 52, the bottom of the spring 51 is fixedly connected to the collecting box 90 and the protrusions on the annular plate 11, the top of the spring 51 is fixedly connected to the annular shell 52, the bottom of the annular shell 52 is provided with an arc-shaped protrusion 521, the top of the conical filter sleeve 41 is fixed with a top rod 411 used in conjunction with the arc-shaped protrusion 521, and the annular shell 52 is inlaid with a coarse filter screen 53. The coarse filter screen 53 can effectively remove large particles in the exhaust gas and protect the fine filter plate to prevent it from being blocked by large particles.

[0060] When the conical filter sleeve 41 rotates, the push rod 411 also rotates. During the rotation, the push rod 411 will continuously contact the arc-shaped protrusion 521, and then the push rod 411 will continuously push up the annular shell 52, and then cooperate with the spring 51, so that the annular shell 52 will vibrate.

[0061] Furthermore, the top of the collecting box 90 is connected to the chip feed hole at the top of the annular shell 52 via a hose 91, and the annular shell 52 and the coarse filter 53 are inclined toward the chip feed hole and the hose 91. When the annular shell 52 and the coarse filter 53 vibrate, the waste chips on the coarse filter 53 move toward the chip feed hole and the hose 91, and enter the collecting box 90 through the hose 91.

[0062] The outer ring of the conical filter sleeve 41 passes through the collection box 90. The collection box 90 is provided with a hole near the conical filter sleeve 41. The hole is located at the waste cleaning rod 44. The fine filter screen 43 is designed to be inclined. When the waste cleaning rod 44 cleans the fine filter screen 43, the waste gathers near the hole and enters the collection box 90 through the hole.

[0063] A baffle 92 is installed at the chip taking opening where the outer ring of the box body 10 is connected to the collecting box 90. By opening the baffle 92, waste chips can be taken out from the chip taking opening.

[0064] Furthermore, the transmission structure 60 includes a slide 61 fixed at the bottom of the inner cavity of the box body 10, and a slide plate 62 slides on the slide 61. The slide plate 62 can slide along the extension direction of the slide 61. A driving disk 63 is provided at the center of the slide plate 62. A plurality of protruding rods are fixed to the top of the driving disk 63. These protruding rods are engaged with the protruding teeth of the inner ring of the slide plate 62. The bottom of the driving disk 63 is rotatably connected to the slide 61. In addition, the top of the driving disk 63 is fixedly connected to the driving rod 15. The rotation of the driving rod 15 can drive the driving disk 63 to rotate, thereby driving the slide plate 62 to slide back and forth.

[0065] Furthermore, the exhaust structure 70 includes an air pipe 71 installed on the annular plate 11 and connected to the suction chamber, the air pipe 71 is provided with a pressure valve 72, a pressure column 73 slides inside the air pipe 71, the pressure column 73 is fixedly connected to the slide plate 62, and the push plate 80 passes through the annular plate 11 and is fixedly connected to the slide plate 62.

[0066] During operation, the slide plate 62 slides back and forth, thereby driving the pressure column 73 and the push plate 80 to slide back and forth at the same time. When the pressure column 73 leaves the air pipe 71, the exhaust gas in the suction chamber will enter the air pipe 71. When the pressure column 73 enters the air pipe 71 again, it will squeeze the exhaust gas in the air pipe 71 to open the pressure valve 72. After opening, the exhaust gas in the air pipe 71 contacts the water in the adsorption chamber, and is discharged from the box body 10 after being fully cooled and purified. During this process, the motor 14 and the induced fan blades 16 do not need to be turned off, and the entire exhaust process is continuous, which avoids frequent starting and stopping of the motor 14, accelerating the wear of the motor 14, and increasing the energy consumption of the motor 14. No additional control system is required to coordinate the starting and stopping of the motor 14, which increases the complexity of the system.

[0067] At the same time, the push plate 80 reciprocates in the water, pushing the water surface in the adsorption chamber to form waves, thereby pushing away the particles floating on the water surface, making it easier to discharge the purified exhaust gas. The movement of the push plate 80 and the exhaust gas discharge by the pressure valve 72 are carried out simultaneously.

[0068] Furthermore, an air inlet pipe 101 and a water inlet pipe 102 are provided on the top of the box body 10, a drain pipe 103 is installed on the annular plate 11, the drain pipe 103 is connected to the cooling chamber, the drain pipe 103 runs through the outside of the box body 10, an air outlet pipe 104 and a water inlet pipe 105 are fixed to the bottom of the outer ring of the box body 10, these two pipes are connected to the adsorption chamber, and a water outlet pipe 106 is also fixed to the bottom of the box body 10, and the water outlet pipe 106 is also connected to the adsorption chamber.

[0069] During operation, the exhaust gas enters the solid filter chamber from the air inlet pipe 101, the solid particles are filtered out, the exhaust gas enters the suction chamber through the air vent 111, then enters the adsorption chamber through the air supply pipe 71 and the pressure valve 72, and is finally discharged through the air outlet pipe 104; the water in the cooling chamber enters through the water inlet pipe 102 and is discharged through the drain pipe 103; the water in the adsorption chamber enters through the water inlet pipe 105 and is discharged through the water outlet pipe 106.
