[0004] However, the current exhaust gas treatment device has the following problems: after the activated carbon is saturated with organic matter in the exhaust gas, it is not convenient to quickly switch the activated carbon, and the organic matter and pollutants in the exhaust gas cannot be effectively adsorbed or removed, resulting in excessive emissions of harmful substances in the exhaust gas, which will cause harm to the environment and human health. Therefore, we proposed a natural gas exhaust gas treatment device based on decorative paper production. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a natural gas tail gas treatment device for decorative paper production, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a natural gas tail gas treatment device for decorative paper production, comprising a device body, an air inlet pipe is fixed at the lower outer wall of the device body, an exhaust pipe is fixed at the top of the device body, a switching device is arranged inside the device body, the switching device comprises a fixed column, the fixed column is fixed to the bottom of the inner wall of the device body, a plurality of partitions are evenly and equidistantly fixed on the outside of the fixed column, a plurality of L-shaped mounting plates are evenly penetrated and slidably installed on the top circumference of the device body, and a single L-shaped mounting plate is located between two adjacent partitions, an activated carbon column is installed on the outer wall of the L-shaped mounting plate, a blocking column is fixed to the bottom of the L-shaped mounting plate, and the blocking column penetrates the bottom of the inner wall of the device body, A storage cylinder is fixed at the bottom of the device body, and an I-shaped cylinder is fixed at the upper inner wall of the device body. A ten-centimeter gap is left between the bottom of the I-shaped cylinder and the bottom of the activated carbon column, and a ten-centimeter gap is left between the fixed column and the top of the inner wall of the device body. The top of the fixed column and the top of the activated carbon column are in the same horizontal plane. When a single activated carbon column is saturated with organic matter in the exhaust gas, the L-shaped mounting plate is pulled upward, and the L-shaped mounting plate drives the activated carbon column to move upward, and the activated carbon column is moved out of the device body. At this time, the saturated activated carbon column can be replaced, and the L-shaped mounting plate will also drive the blocking column to move upward, and the blocking column will block the position of the activated carbon column that originally needed to be replaced. At this time, the exhaust gas can be purified through other activated carbon columns.

[0007] According to the above technical solution, a pressure plate is slidably installed on the upper outer wall of the L-shaped mounting plate, and a spring is provided between the top of the pressure plate and the top of the inner wall of the L-shaped mounting plate, the top of the pressure plate is in contact with the top of the activated carbon column, and a push rod is fixed on the top of the pressure plate, and the top of the push rod passes through the top of the inner wall of the L-shaped mounting plate. When the exhaust gas is discharged from the exhaust pipe through the activated carbon column, the gas will lift the pressure plate, the spring corresponding to the pressure plate is compressed, and the pressure plate will drive the push rod to move upward. The staff can judge whether the activated carbon column is saturated with adsorption by observing the lifting of the push rod. When the activated carbon column is saturated with organic matter, the gaps in the activated carbon column will be blocked by the organic matter, and at this time, there will be no gas circulation at the activated carbon column.

[0008] According to the above technical solution, a uniform device is arranged at the lower part of the interior of the device body, and the uniform device includes a motor and a rotating ring. The motor is fixed at the outer wall of the device body, and a pulley is fixed at the output end of the motor. The rotating ring is rotatably installed at the lower outer wall of the I-shaped cylinder, and the rotating ring and the pulley are connected by a belt drive. A plurality of fan blades are evenly fixed on the bottom circumference of the rotating ring. The motor drives the pulley to rotate. Under the belt drive, the pulley drives the rotating ring to rotate through the belt, and the rotating ring drives the fan blades to rotate. The fan blades stir the natural gas exhaust gas entering the device body.

[0009] According to the above technical scheme, the uniformizing device also includes a water storage ring box, an annular filter, and several sponge plates. The water storage ring box is fixed to the bottom of the inner wall of the device body, and the annular filter is fixed to the inner top of the water storage ring box, and the top of the annular filter is in contact with the bottom of the I-shaped cylinder. Several sponge plates are respectively fixed on one side of several fan blades close to the center of the rotating ring, and the sponge plates are in contact with the outer wall of the annular filter. At the same time, the sponge plates will absorb moisture inside the water storage ring box, and when the fan blades rotate, they will drive the sponge plates to rotate, and the sponge plates will wet the surface of the annular filter. After the natural gas exhaust enters the inside of the device body, the natural gas exhaust will first contact the wetted annular filter.

[0010] According to the above technical solution, an auxiliary device is arranged on the outside of the I-shaped cylinder, and the auxiliary device includes a plurality of elastic telescopic plates and a plurality of slide plates. The fixed ends of the plurality of elastic telescopic plates are evenly fixed on the top of the inner wall of the I-shaped cylinder, the telescopic end of the elastic telescopic plate passes through the bottom of the inner wall of the I-shaped cylinder, the bottom of the telescopic end of the elastic telescopic plate is arranged in a semicircular shape, and the telescopic end of the elastic telescopic plate is semicircularly located on the movement trajectory of the fan blade. The plurality of slide plates are evenly slidably installed on the bottom of the inner wall of the I-shaped cylinder, a hinged rod is hinged at the upper outer wall of the slide plate, and one end of the hinged rod away from the slide plate is hinged at the outer wall of the telescopic end of the elastic telescopic plate, and a plurality of knocking columns are evenly and equidistantly fixed on one side of the slide plate away from the elastic telescopic plate, and the knocking columns are equidistantly fixed to the I-shaped cylinder. The outer wall of the I-shaped cylinder is in contact with each other. During the rotation of the fanning blade, when the fanning blade rotates to the semicircular position of the telescopic end of the elastic telescopic plate, the fanning blade pushes the semicircular end of the telescopic plate to drive the telescopic end of the elastic telescopic plate to move upward, and the telescopic end of the elastic telescopic plate drives the slide plate to slide in the direction of the elastic telescopic plate through the hinged rod, and the slide plate drives the knocking column away from the outer wall of the I-shaped cylinder. When the fanning blade no longer pushes the semicircular end of the telescopic plate, under the action of the elastic force of the elastic telescopic plate itself, the telescopic end of the elastic telescopic plate is reset and moves downward, and the telescopic end of the elastic telescopic plate drives the slide plate to reset and move through the hinged rod, the slide plate drives the knocking column to reset, and the knocking column knocks on the inner wall of the I-shaped cylinder, the I-shaped cylinder vibrates and transmits the vibration force to the activated carbon column, thereby causing the activated carbon column to vibrate.

[0011] According to the above technical scheme, an L-shaped knocking rod is fixed at the outer wall below the telescopic end of several of the elastic telescopic plates, and one end of the L-shaped knocking rod away from the telescopic end of the elastic telescopic plate is in contact with the bottom of the inner wall of the I-shaped tube. When the telescopic end of the elastic telescopic plate moves upward, the L-shaped knocking rod will be driven to move upward, and the L-shaped knocking rod will be away from the bottom of the inner wall of the I-shaped tube. When the telescopic end of the elastic telescopic plate is reset, the elastic telescopic plate drives the L-shaped knocking rod to reset, and the L-shaped knocking rod knocks on the bottom of the inner wall of the I-shaped tube. The bottom of the inner wall of the I-shaped tube vibrates and transmits the vibration force to the annular filter, thereby causing the annular filter to vibrate.

[0012] The present invention provides a natural gas tail gas treatment device for decorative paper production.

[0013] Beneficial effects:

[0014] (1) The present invention sets a switching device so that the L-shaped mounting plate drives the activated carbon column to move out of the device body, so that the activated carbon column that has been saturated with adsorption can be replaced, and the L-shaped mounting plate will also drive the blocking column to block the position of the activated carbon column that originally needs to be replaced. At this time, the exhaust gas can be purified through other activated carbon columns, thereby avoiding the problem of unpurified exhaust gas overflowing from the activated carbon column to be replaced into the interior of the device body, thereby ensuring that the activated carbon column can be quickly replaced without affecting the treatment of natural gas exhaust gas; at the same time, the pressure plate and the push rod cooperate, so that the staff can judge whether the activated carbon column is saturated with adsorption by observing the lifting of the push rod. When the activated carbon column is saturated with organic matter, the gap of the activated carbon column will be blocked by the organic matter. At this time, there will be no gas circulation at the activated carbon column, so that the pressure plate will not drive the push rod to move upward. At this time, the staff is required to replace the saturated activated carbon column.

[0015] (2) The present invention uses the setting of a uniform device so that the motor, pulley, and rotating ring cooperate to drive the fan blades to stir the natural gas exhaust gas entering the main body of the device. Through the stirring action of the fan blades, the natural gas exhaust gas can contact the surface of the activated carbon column more evenly. The stirring can reduce the dead angle in the airflow and ensure that the harmful substances in the exhaust gas have more sufficient contact with the surface of the activated carbon column, thereby improving the adsorption efficiency of the activated carbon column and reducing the retention time of the gas in the main body of the device; at the same time, the sponge plate, water storage ring box, and fan blades cooperate to wet the surface of the annular filter. After the natural gas exhaust gas enters the main body of the device, the natural gas exhaust gas will first contact the wetted annular filter. The wet annular filter can capture particulate matter, oil smoke or other water-soluble pollutants in the exhaust gas. The water forms a thin film on the surface of the filter, which can make the particles in the exhaust gas easier to capture and adsorb. This has a positive effect on purifying pollutants in natural gas exhaust gas and reducing the emission of harmful gases, and to a certain extent slows down the saturation process of the activated carbon column.

[0016] (3) The present invention sets an auxiliary device so that the fan blades, elastic telescopic plates, hinged rods, and slide plates cooperate to drive the knocking column to knock on the inner wall of the I-shaped cylinder, causing the I-shaped cylinder to vibrate and transmit the vibration force to the activated carbon column, thereby causing the activated carbon column to vibrate. The vibration makes the contact between the airflow and the activated carbon column more frequent and uniform. Under the action of vibration, the gas molecules will collide with the particle surface of the activated carbon column at a higher speed, thereby accelerating the adsorption process and improving the adsorption rate and efficiency. At the same time, the elastic telescopic plate drives the L-shaped knocking rod to knock on the bottom of the inner wall of the I-shaped cylinder. The bottom of the inner wall of the I-shaped cylinder vibrates and transmits the vibration force to the annular filter, thereby causing the annular filter to vibrate. The vibration can effectively break up the particulate matter accumulated on the annular filter and prevent the particulate matter from being too tightly attached to the surface of the annular filter, thereby helping to remove the adsorbed particulate matter faster and ensure the filtration efficiency and service life of the annular filter. In addition, the vibration can reduce the blockage of the annular filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1 - Figure 8 An embodiment of the present invention is: a natural gas tail gas treatment device for decorative paper production, comprising a device body 1, an air intake pipe 2 is fixed at the lower outer wall of the device body 1, an exhaust pipe 3 is fixed at the top of the device body 1, a switching device 4 is arranged inside the device body 1, the switching device 4 comprises a fixing column 41, the fixing column 41 is fixed to the bottom of the inner wall of the device body 1, a plurality of partitions 42 are evenly and equidistantly fixed outside the fixing column 41, a plurality of L-shaped mounting plates 47 are evenly penetrated and slidably installed on the top circumference of the device body 1, and a single L-shaped mounting plate 47 is located between two adjacent partitions 42, an activated carbon column 46 is installed on the outer wall of the L-shaped mounting plate 47, a blocking column 44 is fixed to the bottom of the L-shaped mounting plate 47, and the blocking column 44 penetrates the bottom of the inner wall of the device body 1, a storage cylinder 43 is fixed at the bottom of the device body 1, and the device body 1 An I-shaped cylinder 45 is fixed on the upper inner wall, and a ten-centimeter gap is left between the bottom of the I-shaped cylinder 45 and the bottom of the activated carbon column 46, and a ten-centimeter gap is left between the fixed column 41 and the top of the inner wall of the device body 1, and the top of the fixed column 41 and the top of the activated carbon column 46 are at the same horizontal plane. Through the arrangement of the above structure, the staff can quickly replace the activated carbon column 46 after adsorption saturation, and the L-shaped mounting plate 47 will also drive the blocking column 44 to move upward, and the blocking column 44 will block the position of the activated carbon column 46 that originally needs to be replaced. At this time, the exhaust gas can be purified through other activated carbon columns 46, thereby avoiding the problem of unpurified exhaust gas overflowing from the activated carbon column 46 to be replaced into the interior of the device body 1, thereby ensuring that the activated carbon column 46 can be quickly replaced without affecting the treatment of natural gas exhaust.

[0028] A pressure plate 48 is slidably installed on the upper outer wall of the L-shaped mounting plate 47, and a spring is provided between the top of the pressure plate 48 and the top of the inner wall of the L-shaped mounting plate 47. The top of the pressure plate 48 is in contact with the top of the activated carbon column 46. A push rod 49 is fixed to the top of the pressure plate 48, and the top of the push rod 49 passes through the top of the inner wall of the L-shaped mounting plate 47. Through the arrangement of the above structure, the staff can judge whether the activated carbon column 46 is saturated with adsorption by observing the lifting situation of the push rod 49. When the activated carbon column 46 is saturated with organic matter, the gap of the activated carbon column 46 will be blocked by the organic matter. At this time, there will be no gas circulation at the activated carbon column 46, so that the pressure plate 48 will not drive the push rod 49 to move upward. At this time, the staff is required to replace the saturated activated carbon column 46.

[0029] A uniform device 5 is provided at the lower part of the device body 1, and the uniform device 5 includes a motor 51 and a rotating ring 53. The motor 51 is fixed on the outer wall of the device body 1, and a pulley 52 is fixed on the output end of the motor 51. The rotating ring 53 is rotatably installed on the lower outer wall of the I-shaped cylinder 45, and the rotating ring 53 and the pulley 52 are connected by a belt drive. A plurality of fan blades 54 are evenly fixed on the bottom circumference of the rotating ring 53. Through the arrangement of the above structure, the fan blades 54 stir the natural gas exhaust gas entering the device body 1. Through the stirring action of the fan blades 54, the natural gas exhaust gas can be more evenly contacted with the surface of the activated carbon column 46. The stirring can reduce the dead angle in the airflow, and ensure that the harmful substances in the exhaust gas have more sufficient contact with the surface of the activated carbon column 46, thereby improving the adsorption efficiency of the activated carbon column 46 and reducing the residence time of the gas in the device body 1.

[0030] The uniform device 5 also includes a water storage ring box 55, an annular filter 56, and several sponge plates 57. The water storage ring box 55 is fixed to the bottom of the inner wall of the device body 1, and the annular filter 56 is fixed to the inner top of the water storage ring box 55, and the top of the annular filter 56 is in contact with the bottom of the I-shaped cylinder 45. Several sponge plates 57 are respectively fixed to the side of several fan blades 54 close to the center of the rotating ring 53, and the sponge plates 57 are in contact with the outer wall of the annular filter 56. Through the setting of the above structure, the sponge plate 57 will wet the surface of the annular filter 56. After the natural gas exhaust enters the inside of the device body 1, the natural gas exhaust will first contact the wetted annular filter 56. The wet annular filter 56 can capture particulate matter, oil smoke or other water-soluble pollutants in the exhaust. The water forms a thin film on the surface of the filter, which can make the particles in the exhaust easier to be captured and adsorbed. This has a positive effect on purifying pollutants in natural gas exhaust and reducing the emission of harmful gases, and to a certain extent slows down the saturation process of the activated carbon column 46.

[0031] When in use, the natural gas exhaust gas enters the device body 1 through the intake pipe 2, and the activated carbon column 46 will adsorb and filter the organic matter and pollutants in the natural gas exhaust gas, and finally the purified gas will be discharged through the exhaust pipe 3. When a single activated carbon column 46 adsorbs saturated organic matter in the exhaust gas, the L-shaped mounting plate 47 is pulled upward, and the L-shaped mounting plate 47 drives the activated carbon column 46 to move upward, and the activated carbon column 46 is moved out of the device body 1. At this time, the activated carbon column 46 that has been adsorbed saturated can be replaced, and the L-shaped mounting plate 47 will also drive the blocking column 44 to move upward, and the blocking column 44 will block the position of the activated carbon column 46 that originally needs to be replaced. At this time, the exhaust gas can be purified through other activated carbon columns 46, thereby avoiding unpurified exhaust gas from the to-be-replaced activated carbon column. The problem of overflow of the activated carbon column 46 from the inside of the device body 1 is solved, thereby ensuring that the activated carbon column 46 can be quickly replaced without affecting the natural gas exhaust treatment; when the exhaust gas is discharged from the exhaust pipe 3 through the activated carbon column 46, the gas will lift the pressure plate 48, the spring corresponding to the pressure plate 48 is compressed, and the pressure plate 48 will drive the push rod 49 to move upward. The staff can judge whether the activated carbon column 46 is saturated with adsorption by observing the lifting of the push rod 49. When the activated carbon column 46 is saturated with organic matter, the gap of the activated carbon column 46 will be blocked by the organic matter. At this time, there will be no gas circulation at the activated carbon column 46, so that the pressure plate 48 will not drive the push rod 49 to move upward. At this time, the staff is required to replace the saturated activated carbon column 46.

[0032] The motor 51 is started, and the motor 51 drives the pulley 52 to rotate. Under the belt drive, the pulley 52 drives the rotating ring 53 to rotate through the belt, and the rotating ring 53 drives the fan blade 54 to rotate. The fan blade 54 stirs the natural gas exhaust gas entering the device body 1. Through the stirring action of the fan blade 54, the natural gas exhaust gas can contact the surface of the activated carbon column 46 more evenly. The stirring can reduce the dead angle in the airflow, ensure that the harmful substances in the exhaust gas have more sufficient contact with the surface of the activated carbon column 46, thereby improving the adsorption efficiency of the activated carbon column 46 and reducing the retention time of the gas in the device body 1; at the same time, the sponge plate 57 will absorb the moisture inside the water storage ring box 55, and when the fan blade 54 rotates, it will drive the sponge plate 57 to rotate, and the sponge plate 57 will wet the surface of the annular filter 56. After the natural gas exhaust gas enters the inside of the device body 1, the natural gas exhaust gas will first contact the wetted annular filter 56, and the wet annular filter 56 can capture particulate matter, oil smoke or other water-soluble pollutants in the exhaust gas. The moisture forms a thin film on the filter surface, which makes it easier to capture and adsorb particles in the exhaust gas. This has a positive effect on purifying pollutants in natural gas exhaust and reducing the emission of harmful gases, and to a certain extent slows down the saturation process of the activated carbon column 46.

[0033] See also Figure 1 - Figure 8On the basis of the above embodiment, in another embodiment of the present invention, an auxiliary device 6 is provided outside the I-shaped cylinder 45 .

[0034] The auxiliary device 6 includes a plurality of elastic telescopic plates 61 and a plurality of slide plates 62. The fixed ends of the plurality of elastic telescopic plates 61 are uniformly fixed on the top of the inner wall of the I-shaped cylinder 45. The telescopic ends of the elastic telescopic plates 61 penetrate the bottom of the inner wall of the I-shaped cylinder 45. The bottom of the telescopic end of the elastic telescopic plate 61 is arranged in a semicircular shape. The semicircular telescopic end of the elastic telescopic plate 61 is located on the motion trajectory of the fan blade 54. The plurality of slide plates 62 are uniformly slidably installed on the bottom of the inner wall of the I-shaped cylinder 45. A hinged rod 64 is hinged at the upper outer wall of the slide plate 62. The end of the hinged rod 64 away from the slide plate 62 is hinged to the outer wall of the telescopic end of the elastic telescopic plate 61. At the wall, a plurality of knocking columns 63 are evenly and equidistantly fixed on one side of the slide plate 62 away from the elastic telescopic plate 61, and the knocking columns 63 are in contact with the outer wall of the I-shaped cylinder 45. Through the arrangement of the above-mentioned structure, the knocking columns 63 knock on the inner wall of the I-shaped cylinder 45, and the I-shaped cylinder 45 vibrates and transmits the vibration force to the activated carbon column 46, thereby causing the activated carbon column 46 to vibrate. The vibration makes the contact between the airflow and the activated carbon column 46 more frequent and uniform. Under the action of vibration, the gas molecules will collide with the particle surface of the activated carbon column 46 at a higher speed, thereby promoting the acceleration of the adsorption process and improving the adsorption rate and efficiency.

[0035] An L-shaped knocking rod 65 is fixed to the outer wall below the telescopic end of several elastic telescopic plates 61, and one end of the L-shaped knocking rod 65 away from the telescopic end of the elastic telescopic plate 61 contacts the bottom of the inner wall of the I-shaped cylinder 45. Through the arrangement of the above-mentioned structure, the L-shaped knocking rod 65 knocks on the bottom of the inner wall of the I-shaped cylinder 45, and the bottom of the inner wall of the I-shaped cylinder 45 vibrates and transmits the vibration force to the annular filter 56, thereby causing the annular filter 56 to vibrate. The vibration can effectively break up the particles accumulated on the annular filter 56 and prevent the particles from adhering too tightly to the surface of the annular filter 56, thereby helping to remove the adsorbed particles faster and ensure the filtering efficiency and service life of the annular filter 56. In addition, the vibration can reduce the blockage of the annular filter 56.

[0036] When in use, during the rotation of the fan blade 54, when the fan blade 54 rotates to the semicircular position of the telescopic end of the elastic telescopic plate 61, the fan blade 54 pushes the telescopic end of the elastic telescopic plate 61 to drive the telescopic end of the elastic telescopic plate 61 to move upward, and the telescopic end of the elastic telescopic plate 61 drives the slide plate 62 to slide in the direction of the elastic telescopic plate 61 through the hinge rod 64, and the slide plate 62 drives the knocking column 63 away from the outer wall of the I-shaped cylinder 45. When the fan blade 54 no longer pushes the telescopic end of the elastic telescopic plate 61, under the action of the elastic force of the elastic telescopic plate 61 itself, the telescopic end of the elastic telescopic plate 61 is reset and moves downward, and the telescopic end of the elastic telescopic plate 61 drives the slide plate 62 to reset and move through the hinge rod 64, the slide plate 62 drives the knocking column 63 to reset, and the knocking column 63 knocks on the inner wall of the I-shaped cylinder 45, the I-shaped cylinder 45 vibrates and transmits the vibration force to the activated carbon column 46, thereby causing the activated carbon column 46 to vibrate, and the vibration causes the airflow to vibrate with the activated carbon column 46 The contact between the activated carbon column 46 and the activated carbon column 46 is more frequent and uniform. Under the action of vibration, the gas molecules will collide with the particle surface of the activated carbon column 46 at a higher speed, thereby accelerating the adsorption process and improving the adsorption rate and efficiency. When the telescopic end of the elastic telescopic plate 61 moves upward, it will drive the L-shaped knocking rod 65 to move upward, and the L-shaped knocking rod 65 will move away from the bottom of the inner wall of the I-shaped cylinder 45. When the telescopic end of the elastic telescopic plate 61 is reset, the elastic telescopic plate 61 drives the L-shaped knocking rod 65 to reset, and the L-shaped knocking rod 65 knocks on the bottom of the inner wall of the I-shaped cylinder 45. The bottom of the inner wall of the I-shaped cylinder 45 vibrates and transmits the vibration force to the annular filter 56, thereby causing the annular filter 56 to vibrate. The vibration can effectively break the particles accumulated on the annular filter 56 and prevent the particles from being too tightly attached to the surface of the annular filter 56, thereby helping to remove the adsorbed particles faster and ensure the filtration efficiency and service life of the annular filter 56. In addition, the vibration can reduce the blockage of the annular filter 56.
