Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a device for treating odor of waste gas from tobacco production with noise reduction and dust removal functions. Background Art

[0002] A large amount of waste gas is generated during the tobacco production process. The waste gas contains solid impurities such as smoke and dust, as well as harmful gases. If it is discharged directly, it will cause pollution to the environment. Generally, it is necessary to remove the smoke and dust in the waste gas through a filter, and then the remaining harmful gases need to be adsorbed by activated carbon before they can be discharged.

[0003] However, the existing exhaust gas treatment equipment often becomes clogged after long-term use when removing smoke and dust through the filter, and the filter needs to be replaced or cleaned regularly, and the working efficiency cannot be guaranteed. Summary of the invention

[0004] The object of the present invention is to provide a tobacco production waste gas odor treatment device with noise reduction and dust removal functions to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution for tobacco production waste gas odor treatment equipment with noise reduction and dust removal functions, the waste gas odor treatment equipment includes a treatment tank, a dust removal mechanism and an adsorption mechanism, the treatment tank is provided with an air inlet pipe and an air outlet pipe, the dust removal mechanism and the adsorption mechanism are arranged in sequence in the treatment tank along the flow direction of the waste gas, the dust removal mechanism is tightly connected to the treatment tank, and the adsorption mechanism is tightly connected to the treatment tank.

[0006] A large amount of waste gas is generated during the tobacco production process. The waste gas contains a large amount of smoke and harmful gases. Appropriate equipment is needed to treat the waste gas to ensure that the discharged waste gas meets the standards. The waste gas to be treated enters the tank body through the air inlet pipe on the treatment tank for treatment. The waste gas first passes through the dust removal mechanism, which uses the power of the airflow itself to collect the smoke in the waste gas. Then the waste gas passes through the adsorption mechanism to remove the harmful gases. Finally, the treated gas is discharged from the outlet pipe.

[0007] Several dust removal mechanisms are horizontally arranged in the processing tank, and the several dust removal mechanisms include an outer shell, a guide block, a dust collecting assembly, an adjustment assembly and a drive assembly. The outer shell is tightly connected to the processing tank, an air inlet and an air outlet are arranged in the outer shell, the guide block is tightly connected to the outer shell, the guide block is triangular, and the tip of the guide block faces the air inlet, the dust collecting assembly is tightly connected to the guide block, the adjustment assembly is tightly connected to the guide block, the drive assembly is tightly connected to the guide block, and the drive assembly is transmission-connected to the dust collecting assembly.

[0008] The dust removal efficiency is improved by arranging a number of dust removal mechanisms in the treatment tank. The exhaust gas enters the outer shell from the air inlet. After being guided by the guide block, the airflow will flow along the inclined outer wall surfaces on both sides of the triangular guide block. When the airflow flows to the upper plane of the guide block, flow separation will occur to form a tail recirculation zone, causing the pressure in the recirculation zone to decrease, and two vortices will be formed on the plane of the guide block. The smoke in the exhaust gas will be enriched on the upper plane of the guide block under the action of pressure difference and vortex aggregation. The enriched smoke can be collected by arranging the dust collecting component on the upper plane of the guide block. The driving component is used to drive the dust collecting component to move, thereby realizing the enrichment of the smoke in the exhaust gas by the power of the airflow itself, thereby facilitating the dust collecting component to collect and process the smoke.

[0009] A dust collecting chamber is provided in the guide block, and the dust collecting assembly includes a dust collecting belt and a scraper. The dust collecting belt is transmission-connected to the driving assembly, the adsorption surface of the dust collecting belt is a mesh surface, the scraper is tightly connected to the guide block, and the blade of the scraper abuts against the adsorption surface of the dust collecting belt.

[0010] The driving assembly is used to drive the dust collecting belt to move. The smoke and dust enriched on the plane of the guide block will fall on the adsorption surface of the dust collecting belt under the action of airflow and its own gravity, and the continuously moving dust collecting belt can drive the adsorbed smoke and dust to the scraper. The scraper scrapes the smoke and dust on the dust collecting belt and drops it into the dust collecting chamber for collection, thus realizing uninterrupted collection of smoke and dust. The adsorption surface of the mesh surface can increase the adsorption area of ​​the dust collecting belt, thereby improving the adsorption effect.

[0011] The driving assembly includes a driving motor, a transmission shaft, a bushing, a clamping block and a liquid distribution plate. The driving motor is tightly connected to the outer shell, the output end of the driving motor is transmission-connected to the transmission shaft, the clamping block is slidingly connected to the transmission shaft, the bushing is clamped with the clamping block, the bushing is transmission-connected to the dust collecting belt, the liquid distribution plate is tightly connected to the outer shell, the transmission shaft is rotationally connected to the liquid distribution plate, and the inner cavity of the liquid distribution plate is connected to the adjustment assembly.

[0012] The driving motor is the main power source of the driving component. The driving motor transmits torque to the transmission shaft, thereby driving the transmission shaft to rotate. The clamping block is used to connect the transmission shaft and the sleeve, thereby driving the sleeve to rotate, and then driving the dust collecting belt mounted on the sleeve to move to collect the smoke. The liquid distribution plate is fixed on the outer shell to provide a rotation basis for the transmission shaft. The liquid distribution plate is used to drive the adjustment component to move. The adjustment component is used to adjust the curvature of the edge of the guide block. The curvature of the edge of the guide block is appropriately reduced, and the edge of the guide block is sharper. The separation airflow along the inclined surface of the guide block increases, and the area of ​​the tail reflow zone is increased. The enrichment effect of the smoke will be correspondingly improved. That is, by adjusting the curvature of the edge of the guide block, the enrichment effect of the smoke can be adjusted. The smaller the curvature of the edge of the guide block, the better the enrichment effect of the smoke.

[0013] A liquid conducting channel, an arc groove and a liquid storage tank are provided in the transmission shaft. The liquid conducting channel is connected to the inner cavity of the liquid distribution plate. The driving assembly also includes an arc slider, a support spring and a pressure regulating plate. The arc slider is slidably connected to the arc groove, the arc slider is firmly connected to the block, one end of the support spring is firmly connected to the arc slider, the other end of the support spring is firmly connected to the inner wall of the arc groove, the pressure regulating plate is firmly connected to the arc slider, the pressure regulating plate is slidably connected to the liquid storage tank, the liquid storage tank is connected to the liquid conducting channel, and hydraulic oil is filled in the liquid storage tank.

[0014] When the dust collecting belt is running at no load, the support spring plays the role of supporting the arc slider. At this time, the arc slider is stationary, and the arc slider transmits the torque of the transmission shaft to the sleeve through the clamping block, thereby driving the dust collecting belt on the sleeve to move. When smoke and dust are adsorbed on the dust collecting belt, the mass of the dust collecting belt increases, the pressure on the sleeve also increases, the friction between the dust collecting belt and the sleeve also increases accordingly, and the reaction force of the dust collecting belt on the sleeve also increases accordingly, so that a relative offset occurs between the sleeve and the transmission shaft, and the offset direction is opposite to the rotation direction of the transmission shaft. At this time, the arc slider slides to one side along the arc groove driven by the clamping block, the support spring is stretched by force, and the pressure regulating plate slides along the liquid storage tank driven by the arc slider, and the hydraulic oil in the liquid storage tank is pressed into the liquid guide channel, thereby transmitting the pressure to the inner cavity of the liquid distribution plate, thereby driving the adjustment component to move; and the more smoke and dust adsorbed on the dust collecting belt, the greater the reaction force of the dust collecting belt on the sleeve, the greater the angle of the sleeve relative to the transmission shaft, and the greater the pressure transmitted to the adjustment component.

[0015] The adjustment component includes a guide sleeve, a piston rod, an elastic membrane and a push rod. The guide sleeve is hinged to the guide block. An adjustment chamber is provided in the guide sleeve. The adjustment chamber is communicated with the inner chamber of the liquid distribution disk. One end of the piston rod is slidably connected to the adjustment chamber. The other end of the piston rod is hinged to the push rod. A guide groove is provided on the guide block. The push rod is slidably connected to the guide groove. The push rod abuts against the elastic membrane. Both ends of the elastic membrane are tightly connected to the guide block. The vertical cross-section of the elastic membrane is arc-shaped.

[0016] When the amount of smoke adsorbed on the dust collecting belt increases, it means that the smoke content in the exhaust gas has increased. At this time, it is necessary to improve the smoke enrichment effect to improve the collection efficiency; in the initial state, the curvature of the elastic membrane arc is small, that is, the edge of the guide block is relatively flat. At this time, the guide block separates a small airflow, and the area of ​​the tail recirculation zone is small, so the smoke enrichment efficiency is small. When the amount of smoke adsorbed on the dust collecting belt increases, the pressure transmitted from the inner cavity of the liquid distribution plate to the regulating cavity will increase accordingly, thereby driving the piston rod to move upward along the regulating cavity, and then driving the push rod to move upward along the guide groove. The elastic membrane is deformed by force, and the curvature of its cross-section gradually increases, that is, the edge of the guide block changes from flat to sharp, the separation airflow increases, and the area of ​​the tail recirculation zone is increased, and the smoke enrichment effect will be improved accordingly, that is, it is realized that the smoke enrichment effect is automatically adjusted according to the smoke content in the exhaust gas, thereby improving the smoke collection effect.

[0017] The cross-sectional area of ​​the liquid storage tank is larger than the cross-sectional area of ​​the regulating cavity.

[0018] The relative offset between the dust collecting belt and the shaft sleeve is small. According to Pascal's principle, by setting the cross-sectional area of ​​the liquid storage tank to be larger than the cross-sectional area of ​​the regulating cavity, the displacement of the pressure regulating plate is amplified, thereby facilitating the change of the shape of the elastic membrane.

[0019] The adsorption mechanism consists of multiple layers of activated carbon.

[0020] Multi-layer activated carbon can absorb harmful gases in exhaust gas to ensure the cleanliness of exhaust gas.

[0021] A sound insulation layer is arranged around the dust removal mechanism.

[0022] When the exhaust gas flows through the dust removal mechanism, it will generate certain noise, and the noise is reduced through the sound insulation layer.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By setting a triangular guide block, the airflow will flow along the inclined outer wall surfaces on both sides of the triangular guide block after being guided by the guide block. When the airflow flows to the upper plane of the guide block, flow separation will occur to form a tail recirculation zone, causing the pressure in the recirculation zone to decrease and forming two vortices on the plane of the guide block. The smoke in the exhaust gas will be enriched on the upper plane of the guide block under the action of the pressure difference and the aggregation of the vortex. By arranging the dust collecting component on the upper plane of the guide block, the enriched smoke can be collected. The driving component is used to drive the dust collecting component to move, thereby realizing the use of the airflow's own power to enrich the smoke in the exhaust gas, thereby facilitating the dust collecting component to collect and process the smoke.

[0025] 2. The smoke and dust accumulated on the plane of the guide block will fall on the adsorption surface of the dust collecting belt under the action of airflow and its own gravity, and the continuously moving dust collecting belt can drive the adsorbed smoke and dust to the scraper. The scraper will scrape the smoke and dust on the dust collecting belt and drop it into the dust collecting chamber for collection, thus realizing the uninterrupted collection of smoke and dust, and only needs to clean the collected smoke and dust in the dust collecting chamber on time, without using a filter for filtering, thus avoiding blockage.

[0026] 3. In the initial state, the curvature of the elastic membrane arc is small, that is, the edge of the guide block is relatively gentle. At this time, the guide block separates a small airflow, the area of ​​the tail reflow zone is small, and the smoke enrichment efficiency is small. When the smoke adsorbed on the dust collecting belt increases, the mass of the dust collecting belt increases, the pressure on the shaft sleeve also increases, and the friction between the dust collecting belt and the shaft sleeve also increases accordingly. The reaction force of the dust collecting belt on the shaft sleeve also increases accordingly, causing a relative offset between the shaft sleeve and the transmission shaft. The offset direction is opposite to the rotation direction of the transmission shaft. At this time, the arc slider slides to one side along the arc groove driven by the block, and the support spring is stretched by force. Driven by the arc-shaped slider, the pressure plate slides along the liquid storage tank, and presses the hydraulic oil in the liquid storage tank into the liquid guide channel, thereby transmitting the pressure to the inner cavity of the liquid distribution plate, and then transmitting the pressure to the adjusting cavity, driving the piston rod to move upward along the adjusting cavity, and then driving the push rod to move upward along the guide groove. The elastic membrane is deformed by force, and the curvature of its cross-section gradually increases, that is, the edge of the guide block changes from gentle to sharp, the separated airflow increases, and the area of ​​the tail reflow zone is increased, and the enrichment effect of the smoke will be correspondingly improved, that is, it is realized that the enrichment effect of the smoke is automatically adjusted according to the content of the smoke in the exhaust gas, thereby improving the collection effect of the smoke.

[0038] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution for a tobacco production waste gas odor treatment device with noise reduction and dust removal functions, the waste gas odor treatment device comprises a treatment tank 1, a dust removal mechanism 2 and an adsorption mechanism 3, the treatment tank 1 is provided with an air inlet pipe 11 and an air outlet pipe 12, the dust removal mechanism 2 and the adsorption mechanism 3 are sequentially arranged in the treatment tank 1 along the flow direction of the waste gas, the dust removal mechanism 2 is tightly connected to the treatment tank 1, and the adsorption mechanism 3 is tightly connected to the treatment tank 1.

[0039] A large amount of waste gas is generated during the tobacco production process. The waste gas contains a large amount of smoke and harmful gases. Appropriate equipment is needed to treat the waste gas to ensure that the discharged waste gas meets the standards; the waste gas to be treated enters the tank body through the air inlet pipe 11 on the treatment tank 1 for treatment, and the waste gas first passes through the dust removal mechanism 2. The dust removal mechanism 2 uses the power of the airflow itself to collect the smoke in the waste gas, and then the waste gas passes through the adsorption mechanism 3 to remove the harmful gases, and finally the treated gas is discharged from the outlet pipe 12.

[0040] There are several dust removal mechanisms 2 arranged horizontally in the processing tank 1, and the several dust removal mechanisms 2 include an outer shell 21, a guide block 22, a dust collecting assembly 23, an adjusting assembly 24 and a driving assembly 25. The outer shell 21 is fastened to the processing tank 1, and an air inlet 211 and an air outlet 212 are provided in the outer shell 21. The guide block 22 is fastened to the outer shell 21, and the guide block 22 is triangular, with the tip of the guide block 22 facing the air inlet 211. The dust collecting assembly 23 is fastened to the guide block 22, the adjusting assembly 24 is fastened to the guide block 22, the driving assembly 25 is fastened to the guide block 22, and the driving assembly 25 is transmission-connected to the dust collecting assembly 23.

[0041] By arranging a plurality of dust removal mechanisms 2 in the processing tank 1, the efficiency of dust removal is improved. The exhaust gas enters the outer shell 21 through the air inlet 211. After being guided by the guide block 22, the airflow will flow along the inclined outer wall surfaces on both sides of the triangular guide block 22. When the airflow flows to the upper plane of the guide block 22, flow separation will occur, forming a tail recirculation zone, causing the pressure in the recirculation zone to decrease, and forming two vortices on the plane of the guide block 22. The smoke in the exhaust gas will be enriched on the upper plane of the guide block 22 under the action of the pressure difference and the aggregation of the vortex. By arranging the dust collecting component 23 on the upper plane of the guide block 22, the enriched smoke can be collected. The driving component 25 is used to drive the dust collecting component 23 to operate, thereby realizing the enrichment of the smoke in the exhaust gas by the power of the airflow itself, thereby facilitating the dust collecting component 23 to collect and process the smoke.

[0042] A dust collecting chamber 221 is provided in the guide block 22, and the dust collecting assembly 23 includes a dust collecting belt 231 and a scraper 232. The dust collecting belt 231 is transmission-connected to the driving assembly 25, and the adsorption surface of the dust collecting belt 231 is a mesh surface. The scraper 232 is tightly connected to the guide block 22, and the blade of the scraper 232 abuts against the adsorption surface of the dust collecting belt 231.

[0043] The driving assembly 25 is used to drive the dust collecting belt 231 to move. The smoke and dust enriched on the plane of the guide block 22 will fall on the adsorption surface of the dust collecting belt 231 under the action of airflow and its own gravity, and the continuously moving dust collecting belt 231 can drive the adsorbed smoke and dust to the scraper 232. The scraper 232 scrapes the smoke and dust on the dust collecting belt 231 and drops it into the dust collecting chamber 221 for collection, thereby realizing uninterrupted collection of smoke and dust. The adsorption surface of the textured surface can increase the adsorption area of ​​the dust collecting belt 231, thereby improving the adsorption effect.

[0044] The driving assembly 25 includes a driving motor 251, a transmission shaft 252, a sleeve 253, a block 254 and a liquid distribution disk 255. The driving motor 251 is tightly connected to the outer shell 21, the output end of the driving motor 251 is transmission-connected to the transmission shaft 252, the block 254 is slidingly connected to the transmission shaft 252, the sleeve 253 is clamped with the block 254, the sleeve 253 is transmission-connected to the dust collecting belt 231, the liquid distribution disk 255 is tightly connected to the outer shell 21, the transmission shaft 252 is rotationally connected to the liquid distribution disk 255, and the inner cavity of the liquid distribution disk 255 is communicated with the adjustment assembly 24.

[0045] The driving motor 251 is the main power source of the driving component 25. The driving motor 251 transmits torque to the transmission shaft 252, thereby driving the transmission shaft 252 to rotate. The clamping block 254 is used to connect the transmission shaft 252 and the shaft sleeve 253, thereby driving the shaft sleeve 253 to rotate, and then driving the dust collecting belt 231 sleeved on the shaft sleeve 253 to move to collect the smoke. The liquid distribution plate 255 is fixed on the shell 21 to provide a rotation basis for the transmission shaft 252. The liquid distribution plate 255 is used to drive the adjustment component 24 to move. The adjustment component 24 is used to adjust the curvature of the edge of the guide block 22. The curvature of the edge of the guide block 22 is appropriately reduced. The sharper the edge of the guide block 22 is, the greater the separation airflow along the inclined surface of the guide block 22 is, the greater the area of ​​the tail reflow zone is, and the enrichment effect of the smoke will be correspondingly improved. That is, by adjusting the curvature of the edge of the guide block 22, the enrichment effect of the smoke can be adjusted. The smaller the curvature of the edge of the guide block 22, the better the enrichment effect of the smoke.

[0046] A liquid conducting channel 2521, an arc groove 2522 and a liquid storage tank 2523 are provided in the transmission shaft 252. The liquid conducting channel 2521 is connected to the inner cavity of the liquid distribution disk 255. The driving assembly 25 also includes an arc slider 256, a support spring 257 and a pressure regulating plate 258. The arc slider 256 is slidably connected to the arc groove 2522, the arc slider 256 is tightly connected to the block 254, one end of the support spring 257 is tightly connected to the arc slider 256, the other end of the support spring 257 is tightly connected to the inner wall of the arc groove 2522, the pressure regulating plate 258 is tightly connected to the arc slider 256, the pressure regulating plate 258 is slidably connected to the liquid storage tank 2523, the liquid storage tank 2523 is connected to the liquid conducting channel 2521, and hydraulic oil is filled in the liquid storage tank 2523.

[0047] When the dust collecting belt 231 is running without load, the support spring 257 plays the role of supporting the arc-shaped slider 256. At this time, the arc-shaped slider 256 is stationary. The arc-shaped slider 256 transmits the torque of the transmission shaft 252 to the shaft sleeve 253 through the clamping block 254, thereby driving the dust collecting belt 231 on the shaft sleeve 253 to move. When the dust collecting belt 231 is adsorbed with smoke, the mass of the dust collecting belt 231 increases, and the pressure on the shaft sleeve 253 also increases. The friction between the dust collecting belt 231 and the shaft sleeve 253 also increases accordingly, and the reaction force of the dust collecting belt 231 on the shaft sleeve 253 also increases accordingly, so that a relative offset occurs between the shaft sleeve 253 and the transmission shaft 252, and the offset direction is the same as the transmission shaft 252. The rotation direction of the shaft 252 is opposite. At this time, the arc-shaped slider 256 slides to one side along the arc-shaped groove 2522 driven by the block 254, the support spring 257 is stretched, and the pressure regulating plate 258 slides along the liquid storage tank 2523 driven by the arc-shaped slider 256, and the hydraulic oil in the liquid storage tank 2523 is pressed into the liquid guide channel 2521, thereby transmitting the pressure to the inner cavity of the liquid distribution plate 255, thereby driving the adjustment component 24 to move; and the more smoke and dust adsorbed on the dust collecting belt 231, the greater the reaction force of the dust collecting belt 231 on the shaft sleeve 253, the greater the angle of the shaft sleeve 253 relative to the transmission shaft 252, and the greater the pressure transmitted to the adjustment component 24.

[0048] The adjusting assembly 24 includes a guide sleeve 241, a piston rod 242, an elastic membrane 243 and a push rod 244. The guide sleeve 241 is hinged to the guide block 22. An adjusting chamber 2411 is provided in the guide sleeve 241. The adjusting chamber 2411 is communicated with the inner chamber of the liquid distribution disk 255. One end of the piston rod 242 is slidably connected to the adjusting chamber 2411. The other end of the piston rod 242 is hinged to the push rod 244. A guide groove 222 is provided on the guide block 22. The push rod 244 is slidably connected to the guide groove 222. The push rod 244 abuts against the elastic membrane 243. Both ends of the elastic membrane 243 are tightly connected to the guide block 22. The vertical cross-section of the elastic membrane 243 is arc-shaped.

[0049] When the amount of smoke adsorbed on the dust collecting belt 231 increases, it means that the smoke content in the exhaust gas has increased. At this time, it is necessary to improve the enrichment effect of the smoke to improve the collection efficiency. In the initial state, the curvature of the arc of the elastic membrane 243 is small, that is, the edge of the guide block 22 is relatively gentle. At this time, the guide block 22 separates a small amount of airflow, and the area of ​​the tail recirculation zone is small, so the enrichment efficiency of the smoke is small. When the amount of smoke adsorbed on the dust collecting belt 231 increases, the pressure transmitted from the inner cavity of the liquid distribution plate 255 to the regulating cavity 2411 is increased. The force will increase accordingly, thereby driving the piston rod 242 to move upward along the adjusting chamber 2411, and then driving the push rod 244 to move upward along the guide groove 222. The elastic membrane 243 is deformed by the force, and the curvature of its cross section gradually increases, that is, the edge of the guide block 22 tends to be sharp from gentle, the separated airflow increases, and the area of ​​the tail recirculation zone is increased. The enrichment effect of the smoke will be improved accordingly, that is, the enrichment effect of the smoke is automatically adjusted according to the content of the smoke in the exhaust gas, thereby improving the collection effect of the smoke.

[0050] The cross-sectional area of ​​the liquid storage tank 2523 is larger than the cross-sectional area of ​​the regulating cavity 2411 .

[0051] The relative offset between the dust collecting belt 231 and the sleeve 253 is small. According to Pascal's principle, by setting the cross-sectional area of ​​the liquid storage tank 2523 to be larger than the cross-sectional area of ​​the regulating chamber 2411, the displacement of the pressure regulating plate 258 is amplified, thereby facilitating the change in shape of the elastic membrane 243.

[0052] The adsorption mechanism 3 is composed of multiple layers of activated carbon.

[0053] Multi-layer activated carbon can absorb harmful gases in exhaust gas to ensure the cleanliness of exhaust gas.

[0054] A sound insulation layer 4 is arranged around the dust removal mechanism 2 .

[0055] When the exhaust gas flows through the dust removal mechanism 2 , a certain amount of noise is generated, and the noise is reduced by the sound insulation layer 4 .

[0056] The working principle of the present invention is as follows: in the initial state, the curvature of the elastic membrane arc is small, that is, the edge of the guide block is relatively gentle. At this time, the guide block separates a small amount of airflow, the area of ​​the tail reflow zone is small, and the smoke enrichment efficiency is small. When the smoke adsorbed on the dust collecting belt increases, the mass of the dust collecting belt increases, the pressure on the shaft sleeve also increases, the friction between the dust collecting belt and the shaft sleeve also increases accordingly, and the reaction force of the dust collecting belt on the shaft sleeve also increases accordingly, causing a relative offset between the shaft sleeve and the transmission shaft, and the offset direction is opposite to the rotation direction of the transmission shaft. At this time, the arc-shaped slider slides to one side along the arc-shaped groove driven by the block. , the supporting spring is stretched under force, and the pressure regulating plate slides along the liquid storage tank driven by the arc-shaped slider, pressing the hydraulic oil in the liquid storage tank into the liquid guide channel, thereby transmitting the pressure to the inner cavity of the liquid distribution plate, and then transmitting the pressure to the regulating cavity, driving the piston rod to move upward along the regulating cavity, and then driving the push rod to move upward along the guide groove. The elastic membrane is deformed under force, and the curvature of its cross-section gradually increases, that is, the edge of the guide block tends to be sharp from gentle, the separated airflow increases, and the area of ​​the tail reflow zone is increased, and the enrichment effect of the smoke will be correspondingly improved, that is, the automatic adjustment of the smoke enrichment effect according to the smoke content in the exhaust gas is realized.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
