[0020] According to the present invention, after the exhaust gas is discharged into the interior of the reaction tank through the air inlet, the exhaust gas will first impact the baffle plate. The arc-shaped design of the side of the baffle plate facing the air inlet can, on the one hand, play a buffering role under the impact of the exhaust gas when the exhaust gas enters the interior of the reaction tank, thereby preventing the exhaust gas from continuously impacting the interior of the reaction tank, causing the exhaust gas and large particles in the exhaust gas to continuously impact the inner wall of the reaction tank and cause damage to the inner wall of the reaction tank. On the other hand, after the exhaust gas impacts the baffle plate, it will be dispersed due to the arc-shaped design of the baffle plate, thereby allowing a part of the large particles in the exhaust gas to be separated from the exhaust gas due to their own gravity, thereby improving the separation effect of the large particles and the exhaust gas.

[0021] In the present invention, when the exhaust gas impacts the baffle plate, the baffle plate drives the feed pipe to move, and the feed pipe drives the blocking rod to move, so that the end of the blocking rod with an inclined side surface moves inside the transition pipe. Since the side surface of the blocking rod is an inclined surface, the gap between the blocking rod and the transition pipe will change during the movement of the blocking rod, thereby controlling the flow rate of the additive inside the transition pipe to the feed pipe, and then controlling the flow rate of the additive into the reaction tank. In this way, the flow rate of the additive can be automatically controlled according to the amount of exhaust gas. The design is ingenious and the automation is high. At the same time, the exhaust gas treatment method that is different from the filter net B can further improve the exhaust gas treatment effect.

[0022] In the process of the screw rod rotating, the piston block a moves along the screw rod. When the piston block a moves inside the sampling cylinder, the piston block a is connected with the reaction tank through the connecting pipe b, so that a part of the exhaust gas finally filtered by the filter screen c can be extracted into the interior of the sampling cylinder. Therefore, a certain amount of samples can be automatically extracted within a certain period of time for the operator to detect whether the exhaust gas finally filtered by the filter screen c is qualified, thereby further improving the treatment effect of the exhaust gas and making it more environmentally friendly.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides an environmentally friendly treatment device for waste gas purification that effectively removes particulate matter, comprising a reaction tank 1 and an air inlet 5 for air intake provided on the reaction tank 1, a buffer mechanism 2 for removing large waste gas particles is arranged inside the reaction tank 1, the buffer mechanism 2 comprises a storage barrel 22 installed on the outside of the reaction tank 1, the bottom of the storage barrel 22 is connected with a connecting pipe a25 extending to the inside of the reaction tank 1, one end of the connecting pipe a25 is connected and sleeved with a transition pipe 23, a feed pipe 24 is slidably arranged outside one end of the transition pipe 23, a baffle plate 21 located on one side of the air inlet 5 is installed at one end of the feed pipe 24, a blocking rod 26 extending to the inside of a telescopic spring 27 is arranged inside the feed pipe 24, the waste gas entering the inside of the reaction tank 1 through the air inlet 5 will first hit the baffle plate 21, so that the baffle plate 21 drives the feeding pipe 24 to slide on the transition pipe 23, and the feeding pipe 24 drives the blocking rod 26 to move inside the transition pipe 23, and then automatically controls the amount of connection pipe a25 to be released according to the force of the exhaust gas hitting the baffle plate 21, and because the outer side of the transition pipe 23 is designed as a slope; the side of the baffle plate 21 facing the air inlet 5 is designed in an arc shape, the baffle plate 21 is fixedly connected to the feeding pipe 24, and the blocking rod 26 is located inside the feeding pipe 24, and a feeding port is set at the end of the feeding pipe 24 connected to the blocking rod 26, and a telescopic spring 27 is fixed at one end of the feeding pipe 24, and the telescopic spring 27 is sleeved on the outer side of the transition pipe 23, the diameter of the middle part of the transition pipe 23 is larger than the diameter of the two end parts, and the end of the blocking rod 26 with a slope on the outer side extends into the middle part of the transition pipe 23;

[0034] See also Figures 1 to 7As shown, when removing large particles from the exhaust gas, after the exhaust gas is discharged into the reactor 1 through the air inlet 5, the exhaust gas will first impact the baffle plate 21. The arc-shaped design of the side of the baffle plate 21 facing the air inlet 5 can, on the one hand, play a buffering role under the impact of the exhaust gas when the exhaust gas enters the reactor 1, thereby preventing the exhaust gas from continuously impacting the interior of the reactor 1, causing the exhaust gas and large particles in the exhaust gas to continuously impact the inner wall of the reactor 1 and damage the inner wall of the reactor 1. On the other hand, after the exhaust gas impacts the baffle plate 21, it will be dispersed due to the arc-shaped design of the baffle plate 21, thereby allowing a part of the large particles in the exhaust gas to be separated from the exhaust gas due to their own gravity, thereby improving the separation effect of the large particles and the exhaust gas. After impacting the baffle plate 21, the exhaust gas flows upward, then is filtered through the filter screen b7, and finally is filtered through the filter screen c8, and finally is transmitted to the subsequent process through the pipeline externally connected to the top of the reactor 1.

[0035] In addition, when the exhaust gas impacts the baffle plate 21, the additive in the storage barrel 22 is transmitted to the inside of the connecting pipe a25, and then transmitted to the inside of the transition pipe 23 by the connecting pipe a25. Since one end of the blocking rod 26 extends into the inside of the transition pipe 23, the additive enters the inside of the discharge pipe 24 through the gap between the transition pipe 23 and the blocking rod 26, and then is put into the inside of the reaction tank 1, purifying the exhaust gas inside the reaction tank 1 and playing an environmental protection role; the additives are: biological additives, used to promote the biodegradation process, mainly used to treat organic pollutants; oxidants, oxidants are usually used in chemical reactions to remove harmful gases and pollutants in the gas, chemical precipitation agents, etc., which can be selected according to actual needs;

[0036] In addition, when the exhaust gas impacts the baffle plate 21, the baffle plate 21 drives the feed pipe 24 to move, and the feed pipe 24 drives the blocking rod 26 to move, so that the end of the blocking rod 26 with a sloped side surface moves inside the transition pipe 23. Since the side surface of the blocking rod 26 is a slope, the gap between the blocking rod 26 and the transition pipe 23 will change during the movement of the blocking rod 26, thereby controlling the flow rate of the additive inside the transition pipe 23 to the feed pipe 24, and then controlling the flow rate of the additive to the inside of the reaction tank 1, thereby automatically controlling the flow rate of the additive according to the exhaust gas volume. The design is ingenious and the automation is high. At the same time, the exhaust gas treatment method different from the filter screen b7 can further improve the exhaust gas treatment effect; when the exhaust gas volume is large, the impact force of the baffle plate 21 is large, so the baffle plate 21 drives the feed pipe 24 to a longer distance, which changes the distance that the blocking rod 26 moves inside the transition pipe 23, thereby increasing the gap between the blocking rod 26 and the transition pipe 23, controlling the amount of additive added to increase, and vice versa, reducing the amount of additive added. This can accurately control the amount of additive, save costs, and greatly improve the exhaust gas treatment effect.

[0037] The interior of the reaction tank 1 is provided with a filter screen a6, a filter screen b7 and a filter screen c8 forming a three-layer filtering structure, and the baffle plate 21 is located between the filter screen a6 and the filter screen b7. A sampling mechanism 3 for extracting the exhaust gas inside the reaction tank 1 as a sample is provided on one side of the reaction tank 1. The sampling mechanism 3 includes a sampling cylinder 31 located outside the reaction tank 1, a motor 32 is provided on the top of the sampling cylinder 31, and a screw rod 36 extending to the inside of the sampling cylinder 31 is provided at the output end of the motor 32. A piston block a33 slides on the screw rod 36. A connecting pipe b34 is connected to one side of the sampling cylinder 31. One end of the connecting pipe b34 is connected to the reaction tank 1 and the connecting point is located above the filter screen c8. During the rotation of the screw rod 36, the piston block a33 moves along the screw rod 36. At the same time, the piston block a33 slides inside the sampling cylinder 31 and uses the connecting pipe b34 to extract the exhaust gas inside the reaction tank 1. The gas enters the sampling cylinder 31 for easy sampling, detection and observation; the bottom of the sampling cylinder 31 is connected with a connecting pipe c35, and a piston block b38 slides inside the storage cylinder 22. One end of the connecting pipe c35 is connected with the storage cylinder 22. When the piston block a33 extracts the exhaust gas inside the reaction tank 1 inside the sampling cylinder 31, the piston block a33 squeezes the gas inside the sampling cylinder 31 into the storage cylinder 22 and forces the piston block b38 inside the storage cylinder 22 to move. The piston block b38 moves to discharge the additive inside the storage cylinder 22 into the connecting pipe a25 at a certain pressure; the sampling cylinder 31 is fixedly set on one side of the reaction tank 1, and the sampling cylinder 31 is located on one side of the storage cylinder 22. A bearing seat is set on the piston block a33, and the bearing seat is connected to the screw 36 through a ball nut pair. A guide rod 37 for guiding the movement of the piston block b38 is set inside the storage cylinder 22;

[0038] See also Figures 4 to 8 As shown, in the process of exhaust gas being finally filtered by the filter screen c8 and then transmitted to the subsequent process by the external pipeline on the top of the reaction tank 1, the motor 32 is started, and the output end of the motor 32 drives the screw rod 36 to rotate. Since a bearing seat is provided on the piston block a33, and the bearing seat and the screw rod 36 are connected by a ball nut pair, during the rotation of the screw rod 36, the piston block a33 moves along the screw rod 36. While the piston block a33 moves inside the sampling cylinder 31, the piston block a33 is connected to the reaction tank 1 through the connecting pipe b34, so that a part of the exhaust gas finally filtered by the filter screen c8 can be extracted into the interior of the sampling cylinder 31. Therefore, a certain amount of samples can be automatically extracted within a certain period of time for the operator to detect whether the exhaust gas finally filtered by the filter screen c8 is qualified, thereby further improving the exhaust gas treatment effect and making it more environmentally friendly.

[0039] In addition, while the piston block a33 extracts the exhaust gas inside the reaction tank 1 as a sample, the piston block a33 squeezes the gas inside the sampling tube 31 into the interior of the storage tube 22, and forces the piston block b38 inside the storage tube 22 to move. The movement of the piston block b38 discharges the additive inside the storage tube 22 into the connecting tube a25 at a certain pressure; thereby, a certain amount of additive can be automatically added in cooperation with the buffer mechanism 2 without the need for an additional power source. The design is ingenious and more environmentally friendly.

[0040] The reaction tank 1 is provided with a spray mechanism 4 for filtering large particles in the exhaust gas multiple times. The spray mechanism 4 includes a water pump 41 located outside the reaction tank 1. The water pumping end of the water pump 41 is located below the filter screen a6. The water outlet end of the water pump 41 is provided with a water pumping pipe 42 extending to the inside of the reaction tank 1. A spray pipe 43 is provided at one end of the water pumping pipe 42. The spray pipe 43 is located between the filter screen b7 and the filter screen c8.

[0041] See also Figures 3 to 5 As shown, in the process of removing large particles from waste gas, the water pump 41 is started, and the pumping end of the water pump 41 draws water to the pumping pipe 42 extending to the inside of the reaction tank 1, and then sprayed by the spray pipe 43, which can effectively remove large particles in the waste gas, and is filtered through the filter mesh a6. The water is filtered and gathered by the filter mesh a6 and can be recycled again, saving resources and being more environmentally friendly; in addition, if the additive is a chemical precipitant, the chemical precipitant usually combines with water to form a precipitate to remove particulate matter in the gas. They can help combine particulate matter with water to form heavier particles that are easy to settle. When treating waste gas, the chemical precipitant can work together with water to promote the sedimentation of particulate matter, and further cooperate with each other to greatly increase the large particles in the waste gas.

[0042] A method for treating waste gas using the above-mentioned environmentally friendly waste gas treatment equipment for effectively removing particulate matter comprises the following steps:

[0043] S1: After the exhaust gas enters the reaction tank 1 through the air inlet 5, the exhaust gas impacts the baffle plate 21 to play a buffering role;

[0044] S2: The exhaust gas is then filtered through the filter screen b7 while being double filtered by the water sprayed by the spray mechanism 4;

[0045] S3: While the exhaust gas is being sprayed and filtered, the additives automatically injected by the buffer mechanism 2 can be combined with water to further improve the removal effect of large particles in the exhaust gas;

[0046] S4: The exhaust gas that has undergone multiple filtrations then passes through the filter screen c8 for final filtration and is finally discharged from the external pipe at the top of the reaction tank 1.

[0047] Working principle: When removing large particles from waste gas, the waste gas is discharged into the reactor 1 through the air inlet 5, and the waste gas first impacts the baffle plate 21; the waste gas impacts the baffle plate 21 and flows upward, and then is filtered by the filter screen b7, and finally filtered by the filter screen c8, and finally transmitted to the subsequent process through the pipeline connected to the top of the reactor 1;

[0048] While the exhaust gas impacts the baffle plate 21, the additive inside the storage barrel 22 is transmitted to the inside of the connecting pipe a25, and then transmitted to the inside of the transition pipe 23 by the connecting pipe a25. Since one end of the blocking rod 26 extends into the interior of the transition pipe 23, the additive passes through the gap between the transition pipe 23 and the blocking rod 26 into the interior of the discharge pipe 24, and then is dropped into the interior of the reaction tank 1, thereby purifying the exhaust gas inside the reaction tank 1 and playing an environmental protection role.

[0049] When the exhaust gas is finally filtered through the filter c8 and then transmitted to the subsequent process through the pipe externally connected to the top of the reaction tank 1, the motor 32 is started, and the output end of the motor 32 drives the screw 36 to rotate. Since a bearing seat is provided on the piston block a33, and the bearing seat and the screw 36 are connected by a ball nut pair, during the rotation of the screw 36, the piston block a33 moves along the screw 36. While the piston block a33 moves inside the sampling tube 31, the piston block a33 is connected to the reaction tank 1 through the connecting pipe b34, so that a part of the exhaust gas finally filtered by the filter c8 can be extracted into the interior of the sampling tube 31. Therefore, a certain amount of sample can be automatically extracted within a certain period of time for the operator to detect.

[0050] While the piston block a33 extracts the exhaust gas inside the reaction tank 1 as a sample, the piston block a33 squeezes the gas inside the sampling tube 31 into the inside of the storage tube 22, and forces the piston block b38 inside the storage tube 22 to move. The piston block b38 moves to discharge the additive inside the storage tube 22 into the connecting pipe a25 at a certain pressure; in the process of removing large particles from the exhaust gas, the water pump 41 is started, and the pumping end of the water pump 41 pumps water to the pumping pipe 42 extending to the inside of the reaction tank 1, and then sprayed by the spray pipe 43, which can effectively remove large particles in the exhaust gas, and filter through the filter net a6. The water is filtered and gathered by the filter net a6 and can be recycled, saving resources and being more environmentally friendly.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
