Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and specifically to an industrial waste gas purification device with self-cleaning function. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion or production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead and mercury, beryllium compounds, soot, and industrial dust. They often require purification treatment before emission to reduce their impact on the environment.

[0003] One of the most critical steps in the purification process is the filtration and removal of industrial dust and impurity particles from the exhaust gas. When the filter intercepts dust and particles, fine dust and particles inevitably adhere to the filter holes. After a period of use, this can easily lead to clogging of the filter, which not only reduces the filtration efficiency of the industrial exhaust gas but also increases the subsequent cleaning and maintenance costs. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an industrial waste gas purification device with a self-cleaning function, so as to solve the problem that the filter device in the prior art is prone to clogging after a period of use, which not only reduces the filtration effect of the filter device on industrial waste gas, but also increases the subsequent cleaning and maintenance cost of the filter device.

The processing cylinder is also equipped with connection ports at both ends that are connected to the purification chamber and the gas storage container, respectively. The inner cylinder can rotate to connect the air inlet to the connection port and the output port in sequence.

[0006] Furthermore, the fluid compression assembly includes a piston cylinder, a piston head, a piston rod, and a drive component connected to the processing cylinder. The outer circular surface of the piston head is in close contact with the inner wall of the piston cylinder, and the two are in sliding contact.

[0007] Furthermore, the driving component includes a motor and a turntable. The output end of the motor is coaxially connected to the center of the turntable. A trigger part is provided on the outer circular surface of the turntable. The rotation trajectory of the trigger part intersects with the sliding trajectory of the piston rod. The turntable can make the trigger part contact the piston rod through its own rotation, and drive the piston rod to move.

[0008] Furthermore, an elastic support member is sleeved on the piston rod. The end of the elastic support member away from the turntable is provided with a first plate, and the end closer to the turntable is provided with a second plate. The first plate and the second plate are respectively connected to the processing cylinder and the piston rod.

[0009] Furthermore, the triggering part is a protrusion or groove extending radially along the turntable.

[0010] Furthermore, a rolling element is provided at one end of the piston rod near the turntable. The rolling element is movably connected to the piston rod and contacts the side wall of the turntable.

[0011] Furthermore, the processing cylinder is also equipped with a water washing component and a water suction component, which are arranged sequentially from the inlet to the outlet. The bottom surface of the processing cylinder is provided with a collection chamber for collecting liquid, and the top surface of the collection chamber is connected to the purification chamber.

[0012] Furthermore, the absorbent component includes a sponge sheet, a fixed plate, and a movable plate. The sponge sheet, the fixed plate, and the movable plate are all coaxially arranged with the treatment cylinder. The outer circular surface of the sponge sheet is in contact with the inner circular surface of the treatment cylinder. The fixed plate is fixedly connected to the treatment cylinder, and the movable plate is slidably engaged with the treatment cylinder.

[0013] Furthermore, a connecting sleeve is provided on the side of the movable plate away from the fixed plate. A transmission rod is provided inside the connecting sleeve.

[0015] The beneficial effects of this invention are as follows: This industrial waste gas purification device with self-cleaning function uses a fluid compression component in conjunction with a gas storage container. The fluid compression component can increase or decrease the pressure inside the gas storage container, creating a pressure difference between it and the purification chamber. Under the action of the pressure difference, the gas in the gas storage container is sequentially input into the purification chamber through the connection port and the vent. The output airflow blows air onto the vent, blowing off some of the dust particles and impurities attached to the vent, thus preventing clogging and reducing the filtration effect. This allows the device to maintain continuous operation while performing dust removal.

[0024] Please see Figure 1-8 The present invention provides a technical solution: an industrial waste gas purification device with self-cleaning function, including a treatment cylinder 1 with a purification chamber inside, an inlet 101 communicating with the purification chamber at one end of the treatment cylinder 1; an inner cylinder 2 is rotatably disposed inside the treatment cylinder 1, the outer wall of the inner cylinder 2 is tightly fitted with the inner wall of the treatment cylinder 1 and the two are rotatably connected, and an outlet 102 and a vent 201 are respectively provided on the treatment cylinder 1 and the inner cylinder 2; The processing cylinder 1 is also provided with a fluid compression component 3 and a gas storage container 4. One end of the gas storage container 4 is connected to the fluid compression component 3. The processing cylinder 1 is also provided with a connection port 5 that is connected to the purification chamber and the gas storage container 4 at both ends respectively. The inner cylinder 2 can rotate to make the air inlet 201 connect to the connection port 5 and the outlet 102 in sequence.

[0025] In this scheme, the inner wall of the processing cylinder 1 is provided with an annular groove structure, and the outer circular surface of the inner cylinder 2 is provided with a limiting ring located in the annular groove. The limiting ring slides in the annular groove, and under the cooperation of the limiting ring and the annular groove, it forms radial and axial constraints on the inner cylinder 2, making it difficult for the inner cylinder 2 to be displaced, and maintaining rotational cooperation with the processing cylinder 1.

[0026] The vent 201 is displaced as the inner cylinder 2 rotates, moving along a circular trajectory. Both the output port 102 and the connection port 5 are on this displacement path. Therefore, the vent 201 can connect to both the output port 102 and the connection port 5 through the rotation of the inner cylinder 2. The position of the connection port 5 relative to the output port 102 causes the vent 201 to connect to the output port 102 first, and then to the output port 102; or, the position of the connection port 5 relative to the output port 102 causes the vent 201 to connect to the output port 102 first, and then to the connection port 5. When the vent 201 is opposite the connection port 5, the purification chamber is connected to the gas storage container 4; when the vent 201 is opposite the output port 102, the purification chamber is connected to the outside. The fluid compression component 3 works in conjunction with the gas storage container 4. The fluid compression component 3 can increase or decrease the pressure inside the gas storage container 4, creating a pressure difference between it and the purification chamber. Under the action of the pressure difference, the gas in the gas storage container 4 is sequentially input into the purification chamber through the connection port 5 and the vent 201. The output airflow blows air onto the vent 201, blowing off some of the dust particles and impurities attached to the vent 201, thus preventing clogging and reducing the filtration effect. This allows the entire device to maintain continuous operation while performing dust removal.

[0027] The air vent 201 on the inner cylinder 2 may be equipped with a filter structure to enhance the overall filtration effect of the device.

[0028] The output port 102 and the vent 201 can adopt a multi-hole structure. Specifically, both the output port 102 and the vent 201 are composed of multiple perforations distributed along the axial direction of the processing cylinder 1. The output port 102 has multiple sets distributed along the circumferential direction of the processing cylinder 1. The vent 201 can be connected to multiple sets of output ports 102 in sequence by rotation to allow the gas inside the processing cylinder 1 to be output.

[0029] In this embodiment, the fluid compression assembly 3 includes a piston cylinder 301, a piston head 302, a piston rod 303, and a drive member 304 connected to the processing cylinder 1. The outer circular surface of the piston head 302 is in close contact with the inner wall of the piston cylinder 301, and the two are in sliding contact. One end of the piston rod 303 is connected to the side wall of the piston head 302, and the other end extends to the outside of the piston cylinder 301 and is connected to the drive member 304. The end of the piston cylinder 301 away from the piston rod 303 is connected to the gas storage container 4. A one-way valve 6 is provided on the side of the piston cylinder 301 near the gas storage container 4.

[0030] Among them, the one-way output direction of the one-way valve 6 is inside the piston cylinder 301, that is, the input end is connected to the outside, and the output end is connected to the piston head 302.

[0031] In this design, the piston cylinder 301 and the piston head 302 cooperate to form a piston structure. The two are tightly and slidingly fitted together, forming a variable volume chamber in the piston cylinder 301 that is connected to the connection port 5. The piston head 302 can be driven to reciprocate linearly within the piston cylinder 301 by the cooperation of the piston rod 303 and the driving member 304.

[0032] When the piston head 302 moves away from the gas storage container 4, the volume of the chamber on the side where the piston cylinder 301 is connected to the gas storage container 4 increases and a negative pressure is formed. At this time, air is drawn from the outside into the piston cylinder 301 through the one-way valve 6. Then, when the piston head 302 moves closer to the gas storage container 4, the volume of the chamber on the side where it is connected to the gas storage container 4 decreases and a pressurization is formed. At this time, the air in the piston cylinder 301 is forced into the gas storage container 4 through the connecting pipe and temporarily stored.

[0033] In this embodiment, the driving component 304 includes a motor 3041 and a turntable 3042. The output end of the motor 3041 is coaxially connected to the center of the turntable 3042. A trigger part is provided on the outer circular surface of the turntable 3042. The rotation trajectory of the trigger part intersects with the sliding trajectory of the piston rod 303. The turntable 3042 can rotate to make the trigger part contact the piston rod 303 and drive the piston rod 303 to move.

[0034] In this design, the turntable 3042 is driven to rotate by the motor 3041, which in turn drives the trigger part to rotate synchronously in the same direction. Since the rotation trajectory of the trigger part intersects with the movement trajectory of the end of the piston rod 303, the trigger part will contact the piston rod 303 once for every rotation of the turntable 3042. That is, the end of the piston rod 303 away from the piston head 302 contacts the side of the turntable 3042 or the trigger part. During the switching of the contact object, the piston rod 303 will be displaced. The displacement of the piston rod 303, in conjunction with the piston head 302, causes a change in the volume of the chamber on the side where the piston head 302 is connected to the gas storage container 4.

[0035] In this embodiment, an elastic support member 7 is sleeved on the piston rod 303. A first plate 8 is provided at one end of the elastic support member 7 away from the turntable 3042, and a second plate 9 is provided at the other end of the elastic support member 7 near the turntable 3042. The first plate 8 and the second plate 9 are respectively connected to the processing cylinder 1 and the piston rod 303.

[0036] In this scheme, under natural conditions, the elastic force of the elastic support 7 pushes the second plate 9 and drives the piston rod 303 to move in the direction of the turntable 3042. That is, under the action of the elastic force of the elastic support 7, the piston rod 303 maintains the tendency to move in the direction of the turntable 3042 under normal conditions, so that its end remains in contact with the turntable 3042 or the trigger part.

[0037] In this embodiment, the triggering part is a protrusion or groove extending radially along the turntable 3042.

[0038] In this design, the trigger part is a radially protruding block. When the turntable 3042 rotates to a specific angle, the protrusion contacts the end of the piston rod 303. As it continues to rotate, the protrusion directly impacts or pushes the end of the piston rod 303, generating a driving force that causes the piston rod 303 to move in the direction of the piston cylinder 301. As the turntable 3042 continues to rotate, the end of the piston rod 303 gradually disengages from the protrusion. At this time, the elastic support 7 provides a restoring force to the piston rod 303, causing the piston rod 303 to displace. Its end contacts the outer surface of the turntable 3042, preparing for the next displacement.

[0039] The trigger part is a radially recessed groove. When the turntable 3042 rotates to a specific angle, the groove is opposite to the end of the piston rod 303. The elastic support 7 releases its elastic force to push the piston rod 303 into the groove. As the turntable 3042 continues to rotate, the piston rod 303 is squeezed by the inclined surface of the groove, which makes it overcome the elastic force of the elastic support 7 and gradually return to its original position until the end of the piston rod 303 contacts the outer surface of the turntable 3042 again, ready for the next displacement.

[0040] In this embodiment, a rolling element 10 is provided at one end of the piston rod 303 near the turntable 3042. The rolling element 10 is movably connected to the piston rod 303 and is in contact with the side wall of the turntable 3042.

[0041] In this design, the rolling element 10 is installed at the end of the piston rod 303 that contacts the turntable 3042 and can rotate freely. The piston rod 303 contacts the turntable 3042 through the rolling element 10. When the turntable 3042 rotates and drives the piston rod 303 through the trigger, the contact between the piston rod 303 and the turntable 3042 is rolling friction, thereby reducing the wear of the contact surface.

[0042] The rolling element 10 can be a roller or a ball, which rotates in conjunction with the end of the piston rod 303.

[0043] In this embodiment, the processing cylinder 1 is also provided with a water washing component 11 and a water absorption component 12. The water washing component 11 and the water absorption component 12 are arranged sequentially from the inlet 101 to the outlet 102. The bottom surface of the processing cylinder 1 is provided with a collection chamber 16 for collecting liquid. The top surface of the collection chamber 16 is connected to the purification chamber.

[0044] In this design, a water washing assembly 11 and a water suction component 12 are sequentially arranged along the flow path of the exhaust gas from the inlet 101 to the outlet 102. The industrial exhaust gas first passes through the water washing assembly 11, where it comes into contact with water. This allows some of the dust and soluble pollutants in the exhaust gas to be carried away by the water, achieving primary purification and cooling. The water used for washing the exhaust gas then flows naturally into the collection chamber 16 under gravity for centralized treatment and discharge.

[0045] The collection chamber 16 is equipped with a drain pipe, which has a valve structure that can be opened to drain the water in the collection chamber 16.

[0046] The humid gas, after being washed with water, then passes through the water-absorbing element 12, which can effectively adsorb most of the water droplets and residual fine water mist carried in the gas, making the gas relatively dry before it is discharged.

[0047] In this embodiment, the absorbent component 12 includes a sponge sheet 1201, a fixed plate 1202, and a movable plate 1203. The sponge sheet 1201, the fixed plate 1202, and the movable plate 1203 are all coaxially arranged with the processing cylinder 1. The outer circular surface of the sponge sheet 1201 is in contact with the inner circular surface of the processing cylinder 1. The fixed plate 1202 is fixedly connected to the processing cylinder 1, and the movable plate 1203 is slidably engaged with the processing cylinder 1.

[0048] The inner wall of the processing cylinder 1 is provided with a guide groove extending along its axial direction. A guide block is slidably fitted in the guide groove. The guide block is connected to the side wall of the movable plate 1203. Through the cooperation of the guide groove and the guide block, the movable plate 1203 is constrained so that it can only move along the axial direction of the processing cylinder 1, thereby allowing it to only approach or move away from the fixed plate 1202.

[0049] In this design, the outer edge of the cylindrical sponge sheet 1201 is in close contact with the inner wall of the treatment cylinder 1, ensuring that all passing gas must pass through the sponge body. The porous structure of the sponge intercepts and adsorbs moisture in the gas. The fixed plate 1202 is stationary, while the movable plate 1203 can slide axially. When the movable plate 1203 is driven to move towards the fixed plate 1202, it squeezes the sponge sheet 1201 located between them. When the sponge is squeezed, the wastewater adsorbed inside is discharged and drips into the collection chamber 16 below. After squeezing, the sponge returns to a loose state, maintaining high adsorption capacity. Periodic squeezing prevents the sponge from becoming ineffective due to water saturation and can remove particles clogging the pores of the sponge, achieving self-cleaning.

[0050] In this embodiment, a connecting sleeve 14 is provided on the side of the movable plate 1203 away from the fixed plate 1202. A transmission rod 15 is provided inside the connecting sleeve 14. One end of the transmission rod 15 is located inside the connecting sleeve 14, and a bidirectional spiral groove extending along the axial direction of the processing cylinder 1 is opened on its outer surface. A slider is slidably fitted in the bidirectional spiral groove. The slider is connected to the inner wall of the connecting sleeve 14. The end of the transmission rod 15 away from the connecting sleeve 14 is connected to the motor 3041 for transmission.

[0051] In this scheme, when the transmission rod 15 rotates, the slider is restricted from rotating by the connecting sleeve 14 and can only move along the axial direction of the processing cylinder 1. The direction of the bidirectional spiral groove forces the slider to reciprocate along the axial direction, thereby driving the connecting sleeve 14 and the movable plate 1203 fixed thereto to move linearly. Under the bidirectional guidance of the bidirectional spiral groove, it reciprocates, thereby realizing the periodic squeezing and releasing of the sponge.

[0052] The transmission rod 15 is also connected to the turntable 3042 and the inner cylinder 2. Therefore, when the motor 3041 drives the transmission rod 15 to rotate, it can also drive the turntable 3042 and the inner cylinder 2 to rotate synchronously.

[0053] In this embodiment, the water washing assembly 11 includes two conical plates 1101 with matching conical surfaces. The tips of the two conical plates 1101 face the same direction, and a gap is formed between the two conical plates 1101. A water inlet pipe 1102 is provided on the treatment cylinder 1. One end of the water inlet pipe 1102 is connected to a water supply device, and the other end passes through the middle part of one of the conical plates 1101 and communicates with the gap between the two conical plates 1101.

[0054] In this design, two conical plates 1101 are installed in an overlapping manner, forming an annular gap between them. Water output from the water inlet pipe 1102 enters this gap, and the water flow accelerates, diffuses, and impacts the inner conical surface of the opposite conical plate 1101 within the narrow gap, thus forming a water curtain or a combination of water droplets and a water curtain. When exhaust gas enters from the periphery of the conical plates 1101 and passes through this water curtain area, dust particles collide violently with and agglomerate with the water droplets, thus being captured.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
