The one in the first cavity 11 is responsible for adsorbing the exhaust gas, and the honeycomb adsorbent in the second cavity 12 completes the washing at the same time. When the first motor 21 rotates the honeycomb adsorbent to the second cavity 12, the gas in the air collecting hood 27 blows away the impurities and dust on the surface or inner wall of the honeycomb adsorbent. At the same time, the honeycomb adsorbent rotates with the first rod 23 as the axis, so that the gas in the air collecting hood 27 can be blown directly to the side wall of the honeycomb adsorbent, so that the impurities are removed more thoroughly.

At the same time, the first rod 23 at the proximal end of the ring block 19 slides in the sliding groove 33. Because the first rod 23 has a locking transverse groove 34, the first rod 23 can slide stably in the sliding groove 33. At the same time, the area of ​​the first cavity 11 is slightly smaller than the second cavity 12, which provides space for the rotation of the honeycomb adsorbent in the second cavity 12. When one end of the first rod 23 rotates to the driving transverse groove 32 in the cylinder 31, at this time, the second motor 3 can drive the first rod 23 in the second cavity 12 to rotate, and at the same time drive the honeycomb adsorbent to rotate, so that the gas in the gas collecting hood 27 can directly blow the side walls of the honeycomb adsorbent at different angles, making the impurity removal more direct, convenient and efficient.

[0050] The transmission member includes a first synchronous wheel 4, the reciprocating screw 26 passes through the tower body 1, the output end of the second motor 3 and the reciprocating screw 26 are fixedly connected with the first synchronous wheel 4, and a pair of the first synchronous wheels 4 are driven by a synchronous belt 41; a guide groove 42 is provided at the bottom of the square groove 25, and the position of the guide groove 42 and the honeycomb adsorbent 24 corresponds; when working, the honeycomb adsorbent is driven to rotate by the second motor 3, and the reciprocating screw 26 is driven to rotate by the synchronous belt 41, and the gas collecting cover 27 is driven to rotate horizontally above the rotating honeycomb adsorbent The air collecting hood 27 moves back and forth and is set to a long and narrow shape, so that the force of the blown wind is greater under the same air volume, thereby avoiding energy waste of the air pump 7; at the same time, by controlling the air output and temperature of the air collecting hood 27, the gas in the air collecting hood 27 can quickly dry or cool the honeycomb adsorbent after the honeycomb adsorbent is eluted by the soaking liquid, and the rotation of the honeycomb adsorbent is conducive to the dripping of the soaking liquid, and the wind can blow directly to all angles of the honeycomb adsorbent, so that the honeycomb adsorbent can be put into the work of adsorbing exhaust gas again as soon as possible.

[0051] The gas delivery component includes an air pump 7, the top of the tower body 1 is fixedly connected to the air pump 7, the gas delivery end of the air pump 7 is fixedly connected to an L-tube, and the L-tube passes through the tower body 1 and is fixedly connected to a hose, and the hose is connected to the top of the air collecting hood 27; when working, by controlling the air volume of the air pump 7, the air collecting hood 27 can not only have the effect of directly blowing the honeycomb adsorbent with a large air volume to remove impurities, but also can make the honeycomb adsorbent quickly blow away the surface moisture after being soaked in the soaking liquid and eluted, so that the honeycomb adsorbent can be quickly dried.

[0052] Embodiment 2

[0053] like Figures 4 to 14 As shown, the guide plates 5 are rotatably connected between the opposite side walls of the air collecting hood 27 through a rotating shaft, the side walls on both sides of the air collecting hood 27 are provided with arc grooves 51, and the upper side walls on both sides of the guide plates 5 are fixedly connected with fixed rods 52, and the opposite side walls of the square groove 25 are provided with sliding grooves 53, and the fixed rods 52 are slidably connected in the arc grooves 51 and the sliding grooves 53; the bottom of the arc groove 51 is provided with a groove 54, and the bottom of the groove 54 is fixedly connected with a block 55 through a group of springs, and the side walls on both sides of the block 55 are provided with inclined surfaces 56, and the positions of the inclined surfaces 56 and the fixed rods 52 correspond to each other; when working, the reciprocating screw 26 drives the air collecting hood 27 to move back and forth laterally and the honeycomb adsorbent to rotate, so that the surface and side walls of the honeycomb adsorbent with the first rod 23 as the axis can be directly blown to avoid the existence of impurities in dead corners, and the guide plate 5 is set , so that the wind direction in the air collecting hood 27 is tilted to both sides, and the fixing rod 52 is fixed between the block 55 and the side wall of one side of the arc groove 51. In this way, the angle of the guide plate 5 is fixed. When the air collecting hood 27 moves to one end of the square groove 25, the fixing rod 52 and the edge side wall of the sliding groove 53 are in hard contact, so that the fixing rod 52 squeezes the inclined surface 56 of the block 55, so that the block 55 presses down the spring until the fixing rod 52 is fixed between the block 55 on the other side and the edge of the arc groove 51, completing the fixing of the inclination angle of the opposite side of the guide plate 5. At this time, the air collecting hood 27 returns and blows directly at the inclination angles on both sides through the fixed position of the guide plate 5, so that the inner wall of the honeycomb adsorbent is all around with direct blowing conditions, avoiding the existence of dead corners for direct blowing of impurities, resulting in impurities remaining on the honeycomb adsorbent, affecting the adsorption performance and service life of the honeycomb adsorbent.

[0054] A square cavity 6 is provided in the tower body 1, and a second rod 61 is rotatably connected to the side wall of the square cavity 6 through a second circular groove, a second synchronous wheel 62 is fixedly connected to the second rod 61, and the second synchronous wheel 62 and a pair of first synchronous wheels 4 are driven by a synchronous belt 41, and the diameter of the first synchronous wheel 4 is larger than the second synchronous wheel 62; a rotating rod 63 is rotatably connected to the bottom of the square cavity 6, and a bevel gear 64 is fixedly connected to the rotating rod 63 and the second rod 61, and the pair of bevel gears 64 are meshed, and the top of the rotating rod 63 passes through the square cavity 6 and is fixedly connected to a group of twisted stirring plates 65; when working, the second motor 3 drives the synchronous belt 41 to drive, the second synchronous wheel 62 drives the second rod 61 to rotate, and at the same time, a group of twisted stirring plates 65 are driven to rotate around the rotating rod 63 as the axis through a pair of bevel gears 64. When the soaking liquid inside the second cavity 12 soaks and elutes the honeycomb adsorbent in the second cavity 12, the second motor 3 can be started intermittently to drive the twisted stirring plates 65 to rotate, so that the elution efficiency is increased.

[0055] Embodiment 3

[0056] like Figures 1 to 4 As shown, a thermostat 8 is fixedly connected to the top of the tower body 1, and the air inlet and outlet ends of the thermostat 8 are connected through a connecting pipe and an L-tube respectively, and valves are provided on the L-tube and the connecting pipe. When working, the temperature of the blown gas in the gas collecting hood 27 is controlled by the thermostat 8, so as to achieve the drying and cooling effects on the honeycomb adsorbent, and serve for completing the elution and post-elution work of the honeycomb adsorbent in different ways.

[0057] A position sensor is fixedly connected to the second cavity 12 through a placement groove, and the position sensor corresponds to the position of the cylinder 31. During operation, the position sensor allows the end of the first rod 23 to accurately enter the driving transverse groove 32 of the cylinder 31 to avoid connection errors that may cause damage to the honeycomb adsorbent during rotation.

[0058] Working principle: the fixed block 2, the ring block 19 and the honeycomb adsorbent are driven to rotate by the first motor 21. The honeycomb adsorbents on both sides of the fixed block 2 are set as two independent parts. The one located in the first cavity 11 is responsible for adsorbing the exhaust gas, and the honeycomb adsorbent in the second cavity 12 completes the elution at the same time. When the first motor 21 rotates the honeycomb adsorbent to the second cavity 12, the gas in the gas collecting hood 27 blows away the impurities and dust on the surface or inner wall of the honeycomb adsorbent. At the same time, the honeycomb adsorbent rotates with the first rod 23 as the axis, so that the gas in the gas collecting hood 27 can be blown directly to the side wall of the honeycomb adsorbent, so that the impurities are removed more thoroughly. Then, hot air or steam is transported to the second cavity 12 through the steam pipe to elute the honeycomb adsorbent in the second cavity 12, so that the equipment can complete the work of eluting and adsorbing the exhaust gas at the same time. The fixed block 2, the first rod 23 and the honeycomb adsorbent are driven to rotate by the first motor 21. At the same time, the first The rod 23 slides in the sliding groove 33. Because the first rod 23 is provided with a locking transverse groove 34, the first rod 23 can slide stably in the sliding groove 33. At the same time, the area of ​​the first cavity 11 is slightly smaller than the second cavity 12. This is to provide space for the honeycomb adsorbent in the second cavity 12 to rotate. When one end of the first rod 23 rotates to the driving transverse groove 32 in the cylinder 31, at this time, the first rod 23 in the second cavity 12 can be driven by the second motor 3 to rotate, and the honeycomb adsorbent is driven to rotate at the same time, so that the gas in the air collecting hood 27 can directly blow the side walls of the honeycomb adsorbent at different angles, making the impurity removal more direct, convenient and efficient. While the honeycomb adsorbent is driven to rotate by the second motor 3, the reciprocating screw 26 is driven to rotate by the synchronous belt 41, and the air collecting hood 27 is driven to move horizontally back and forth above the rotating honeycomb adsorbent. The air collecting hood 27 is set to a long and narrow shape, so that the force of the blown wind is greater under the same air volume, avoiding the air pump 7 from wasting energy;At the same time, by controlling the gas output and temperature of the gas collecting hood 27, the gas in the gas collecting hood 27 can quickly dry or cool the honeycomb adsorbent after the honeycomb adsorbent is eluted by the soaking liquid, and the rotation of the honeycomb adsorbent is conducive to the dripping of the soaking liquid, and the wind can blow directly to all angles of the honeycomb adsorbent, so that the honeycomb adsorbent can be put into the work of adsorbing exhaust gas again as soon as possible. The reciprocating screw 26 drives the gas collecting hood 27 to move back and forth horizontally and the honeycomb adsorbent to rotate, which can directly blow the surface and side walls of the honeycomb adsorbent with the first rod 23 as the axis to avoid the existence of impurities in dead corners. The fixed rod 52 is fixed between the block 55 and the side wall of the arc groove 51, and the angle of the guide plate 5 is fixed in this way. When the air collecting hood 27 moves to one end of the square groove 25, the fixed rod 52 and the edge side wall of the sliding groove 53 are in hard contact, so that the fixed rod 52 squeezes the inclined surface 56 of the block 55, so that the block 55 presses the spring down until the fixed rod 52 is fixed between the block 55 on the other side and the edge of the arc groove 51, completing the fixing of the inclination angle of the opposite side of the guide plate 5. At this time, the air collecting hood 27 returns and blows directly at the inclination angles on both sides through the fixed position of the guide plate 5, so that the opposite side The inner wall of the honeycomb adsorbent is provided with direct blowing conditions all around, so as to avoid the dead corners of impurities being blown directly, resulting in impurities remaining on the honeycomb adsorbent, which affects the adsorption performance and service life of the honeycomb adsorbent. The second motor 3 drives the synchronous belt 41 to transmit, and the second synchronous wheel 62 drives the second rod 61 to rotate. At the same time, a pair of bevel gears 64 drives a group of twisted stirring plates 65 to rotate with the rotating rod 63 as the axis. When the soaking liquid inside the second cavity 12 soaks and elutes the honeycomb adsorbent in the second cavity 12, the second motor 3 can be started intermittently to drive the twisted stirring plates 65 to rotate, so that the elution efficiency is increased. By controlling the air flow of the air pump 7, the air flow of the air pump 7 is increased. The amount of air can make the air collecting hood 27 not only have the effect of directly blowing the honeycomb adsorbent with a large air volume to remove impurities, but also can make the honeycomb adsorbent quickly blow off the surface moisture after being soaked in the soaking liquid and eluted, so that the honeycomb adsorbent can be quickly dried. The temperature of the blown gas in the air collecting hood 27 is controlled by the thermostat 8, which can achieve the drying and cooling effect of the honeycomb adsorbent, and serve the work of eluting and post-eluting the honeycomb adsorbent in different ways. Through the position sensor, the end of the first rod 23 accurately enters the driving transverse groove 32 of the cylinder 31 to avoid connection errors that cause damage to the honeycomb adsorbent during rotation. ;
