Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas adsorption equipment, specifically an adsorption-type exhaust gas treatment device that allows for easy replacement of reagents. Background Technology

[0002] Exhaust gas includes vehicle exhaust and industrial exhaust, with vehicle exhaust accounting for more than 60%. Vehicle exhaust is the exhaust gas emitted from the exhaust pipe of a vehicle. Vehicle exhaust is another major factor in air pollution. Vehicle exhaust contains carbon monoxide, nitrogen oxides, and other solid particles that have adverse effects on human health. Most existing exhaust gas adsorption tanks are fixed structures that cannot be easily disassembled, making them very inconvenient for later maintenance.

[0003] According to a public notice (announcement number: CN215428201U) of an easy-to-maintain exhaust gas adsorption tank, the above application includes an adsorption tank body, an air inlet and an exhaust outlet at both ends of the adsorption tank body, a cover at both ends of the adsorption tank body, the air inlet and the exhaust outlet are set on the cover, the outer side of the cover and the inner wall of the adsorption tank body are provided with corresponding threads, and a protective pad is surrounded around the outer side of the adsorption tank body.

[0004] However, in actual use, the exhaust gas directly enters the adsorption tank and flows to the activated carbon in certain areas. Particulate matter in the exhaust gas may be directly deposited on the surface of the activated carbon, hindering the adsorption effect of its microporous structure. This causes the activated carbon in these areas to become saturated quickly, while the activated carbon in other areas is not fully utilized. In view of this, we propose an adsorption-type exhaust gas treatment device that allows for easy replacement of the reagent. Utility Model Content

[0005] The purpose of this invention is to provide an adsorption-type exhaust gas treatment device that allows for easy replacement of the reagent, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adsorption-type exhaust gas treatment device that facilitates reagent replacement, comprising an installation sleeve, wherein a treatment component is provided on the side wall of the installation sleeve, and the treatment component includes:

[0007] A trapezoidal block is fitted onto the side wall of the mounting sleeve, and an adjusting sleeve is threaded to the right end of the mounting sleeve.

[0008] An agitator sleeve is threaded to the right end of an mounting sleeve. A flow divider plate is fixedly connected to the right end of the agitator sleeve. A mounting bracket is fixedly connected to the inner wall of the agitator sleeve. The mounting bracket is sleeved with a rotating shaft. Blades are fixedly connected to the side wall of the rotating shaft. A connecting groove is provided at the right end of the rotating shaft.

[0009] A reaction sleeve is threadedly connected to the right end of a stirring sleeve. An inner sleeve is fixedly connected to the inner wall of the reaction sleeve. A rotating rod is rotatably connected to the inner wall of the reaction sleeve. An auger is fixedly connected to the side wall of the rotating rod. A connecting block is fixedly connected to the end face of the rotating rod. A crossbar is fixedly connected to the side wall of the rotating rod.

[0010] Preferably, the threads on the outer wall of the mounting sleeve are counterclockwise, and the threads on the outer wall of the agitator sleeve are clockwise, so that the direction of the mounting adjustment sleeve is opposite to the direction of the mounting reaction sleeve.

[0011] Preferably, the trapezoidal block has a right-angled trapezoidal cross-section, the hypotenuse of the trapezoidal block is movably connected to the inner wall of the adjusting sleeve, and the trapezoidal block is magnetically connected to the adjusting sleeve.

[0012] Preferably, the inner sleeve divides the interior of the reaction sleeve into an inner ring and an outer ring, the auger is located in the inner ring, the crossbar is located in the outer ring, and the side wall of the inner sleeve has a slot that connects the inner ring and the outer ring.

[0013] Preferably, the reaction sleeve has a through hole at the end away from the stirring sleeve. The diameter of the through hole is smaller than the diameter of the activated carbon particles, so that only the treated exhaust gas can pass through the through hole, while the activated carbon cannot fall out through the through hole.

[0014] Preferably, a flow guide sleeve is fixedly connected to the inner wall of the mounting sleeve. The flow guide sleeve has a large diameter end and a small diameter end. The large diameter end is fixedly connected to the inner wall of the mounting sleeve, and the small diameter end is located on the side close to the agitation sleeve.

[0015] Compared with the prior art, this utility model provides an adsorption-type exhaust gas treatment device that facilitates reagent replacement, and has the following beneficial effects:

[0016] 1. This convenient adsorption-type tail gas treatment equipment allows for easy replacement of the activated carbon. By rotating the reaction sleeve forward using the designated processing components, the reaction sleeve can be disassembled for replacement. This also ensures a tighter connection between the installation sleeve and the tail gas pipe. The auger stirs the activated carbon particles in the inner ring, continuously agitating them and allowing the tail gas to come into contact with more fresh adsorption surfaces. This improves the adsorption efficiency of the activated carbon for harmful components in the tail gas. The stirring also breaks up any agglomeration or compression that may form in the activated carbon particles during adsorption, maintaining smooth airflow within the adsorption tank. The activated carbon exchanges between the inner and outer rings, preventing overuse or premature saturation in one area while other areas remain underutilized. This evenly distributes the adsorption load and improves the overall utilization efficiency of the activated carbon within the adsorption tank.

[0017] 2. This adsorption-type exhaust gas treatment equipment, which facilitates the replacement of reagents, gradually compresses the exhaust gas flow from a low-speed, large-section state to a high-speed, small-section state through the set guide sleeve. The increased exhaust gas speed directly increases the kinetic energy of the airflow. The high-speed airflow can generate a stronger driving effect on the blade surface, reducing the slow or stagnant blade rotation caused by insufficient airflow speed. The efficient rotation of the blades further drives the rotation of the rotating rod and the auger. Attached Figure Description

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: an adsorption-type exhaust gas treatment device that facilitates reagent replacement, including an installation sleeve 1. The side wall of the installation sleeve 1 is provided with a treatment component 2. The treatment component 2 includes a trapezoidal block 201, an adjusting sleeve 202, a stirring sleeve 203, a flow divider 204, a mounting frame 205, a rotating shaft 206, a connecting groove 207, a blade 208, a reaction sleeve 209, an inner sleeve 210, a rotating rod 211, an auger 212, a connecting block 213, and a crossbar 214.

[0026] In one embodiment of this utility model, the trapezoidal block 201 is sleeved with the side wall of the mounting sleeve 1, and the right end of the mounting sleeve 1 is threaded with an adjusting sleeve 202. The cross-section of the trapezoidal block 201 is a right trapezoid, the hypotenuse of the trapezoidal block 201 is movably connected to the inner wall of the adjusting sleeve 202, and the trapezoidal block 201 and the adjusting sleeve 202 are magnetically connected.

[0027] The agitator sleeve 203 is threaded to the right end of the mounting sleeve 1. A diverter plate 204 is fixedly connected to the right end of the agitator sleeve 203. A mounting bracket 205 is fixedly connected to the inner wall of the agitator sleeve 203. The mounting bracket 205 is sleeved with the rotating shaft 206. A blade 208 is fixedly connected to the side wall of the rotating shaft 206. A connecting groove 207 is provided at the right end of the rotating shaft 206.

[0028] The reaction sleeve 209 is threadedly connected to the right end of the stirring sleeve 203. An inner sleeve 210 is fixedly connected to the inner wall of the reaction sleeve 209. A rotating rod 211 is rotatably connected to the inner wall of the reaction sleeve 209. An auger 212 is fixedly connected to the side wall of the rotating rod 211. A connecting block 213 is fixedly connected to the end face of the rotating rod 211. A crossbar 214 is fixedly connected to the side wall of the rotating rod 211. The inner sleeve 210 divides the interior of the reaction sleeve 209 into an inner ring and an outer ring. The auger 212 is located in the inner ring, and the crossbar 214 is located in the outer ring. A groove is opened on the side wall of the inner sleeve 210, which connects the inner ring and the outer ring. A through hole 3 is opened at the end of the reaction sleeve 209 away from the stirring sleeve 203. The diameter of the through hole 3 is smaller than the diameter of the activated carbon particles, so that the through hole 3 can only allow the treated exhaust gas to pass through, while the activated carbon cannot fall out through the through hole 3.

[0029] The threads on the outer wall of the mounting sleeve 1 are set counterclockwise, and the threads on the outer wall of the stirring sleeve 203 are set clockwise, so that the direction of the mounting adjustment sleeve 202 is opposite to the direction of the mounting reaction sleeve 209.

[0030] Install the mounting sleeve 1 onto the exhaust pipe, then rotate the adjusting sleeve 202 clockwise, causing the adjusting sleeve 202 to push the trapezoidal block 201 tightly against the outer wall of the exhaust pipe, thereby fixing the mounting sleeve 1 onto the exhaust pipe. Then rotate the stirring sleeve 203 clockwise, fixing the stirring sleeve 203 to the mounting sleeve 1. After filling the reaction sleeve 209 with activated carbon granules, rotate the reaction sleeve 209 counterclockwise, fixing the reaction sleeve 209 to the stirring sleeve 203. Before installing the reaction sleeve 209, insert the connecting block 213 into the connecting groove 207. The exhaust gas enters the stirring sleeve 203 through the mounting sleeve 1, driving the blades 208 and the rotating shaft 206 to rotate. The rotating rod 211 and the auger 212 rotate in one step. The auger 212 stirs the activated carbon particles in the inner ring, which makes the activated carbon particles constantly turn over, allowing the exhaust gas to come into contact with more fresh adsorption surfaces, thereby improving the adsorption efficiency of the activated carbon for harmful components in the exhaust gas. Stirring can break up the agglomeration or compression that may form in the activated carbon particles during the adsorption process, ensuring that a certain gap is maintained between the particles, keeping the airflow in the adsorption tank unobstructed, and avoiding local blockage that would reduce the adsorption effect. Rotating the reaction sleeve 209 in the forward direction can remove the reaction sleeve 209 to replace the activated carbon, and at the same time, it can make the connection between the mounting sleeve 1 and the exhaust pipe tighter.

[0031] The rotation of the rotating rod 211 drives the horizontal rod 214 to rotate, and the horizontal rod 214 pushes the activated carbon in the outer ring to flip. Through cooperation with the auger 212, the activated carbon is exchanged between the inner and outer rings, avoiding overuse or premature saturation of activated carbon in a certain area, while the activated carbon in other areas is not fully utilized. This evenly distributes the adsorption load, improves the utilization efficiency of activated carbon in the entire adsorption tank, and extends the overall service life of the adsorption tank.

[0032] When the exhaust gas passes through the splitter plate 204, the stream of exhaust gas is dispersed, and the dispersed exhaust gas forms a dispersed fluid that can cover more of the activated carbon surface, avoid local airflow concentration, and ensure that the exhaust gas can contact the activated carbon particles evenly, thereby improving the adsorption efficiency.

[0033] In addition, a guide sleeve 4 is fixedly connected to the inner wall of the mounting sleeve 1. The guide sleeve 4 has a large diameter end and a small diameter end. The large diameter end is fixedly connected to the inner wall of the mounting sleeve 1, and the small diameter end is located on the side close to the stirring sleeve 203. When the exhaust gas passes through the guide sleeve 4, the guide sleeve 4 gradually shrinks from the large diameter end to the small diameter end, forming a nozzle-like structure. When the fluid passes through the channel with a reduced cross-sectional area, its flow velocity increases and its pressure decreases. This structure gradually compresses the flow of exhaust gas from a low-speed, large-section state to a high-speed, small-section state. The increased exhaust gas velocity directly increases the kinetic energy of the airflow. The high-speed airflow can generate a stronger pushing effect on the surface of the blade 208, reducing the slow rotation or stagnation of the blade 208 caused by insufficient airflow velocity. The efficient rotation of the blade 208 further drives the rotation of the rotating rod 211 and the auger 212, so that the activated carbon particles are more fully stirred.

[0034] In this invention, during use, the mounting sleeve 1 is fitted onto the exhaust pipe. Rotating the adjusting sleeve 202 clockwise pushes the trapezoidal block 201 tightly against the outer wall of the exhaust pipe, thus fixing the mounting sleeve 1 onto the exhaust pipe. Then, rotating the stirring sleeve 203 clockwise fixes it to the mounting sleeve 1. After filling the reaction sleeve 209 with activated carbon granules, rotating the reaction sleeve 209 counterclockwise fixes it to the stirring sleeve 203. Rotating the reaction sleeve 209 clockwise allows it to be removed for replacement of the activated carbon. Simultaneously, the mounting sleeve 1 and the exhaust pipe are connected. The connection between the gas tubes is tighter. After the reaction sleeve 209 is filled with activated carbon particles, the reaction sleeve 209 is rotated in the opposite direction to fix it to the stirring sleeve 203. Before installing the reaction sleeve 209, the connecting block 213 is inserted into the connecting groove 207. The exhaust gas enters the stirring sleeve 203 through the installation sleeve 1. The exhaust gas drives the blade 208 and the rotating shaft 206 to rotate, which in turn drives the rotating rod 211 and the auger 212 to rotate. The auger 212 stirs the activated carbon particles in the inner ring, which can make the activated carbon particles turn over continuously, so that the exhaust gas comes into contact with more fresh adsorption surfaces and improves the adsorption efficiency of activated carbon for harmful components in the exhaust gas.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
