Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to an environmentally friendly waste gas treatment device for glue processing. Background Art

[0002] Glue is an intermediate connecting two materials, mostly in the form of water-based solution. The production of glue involves multiple steps, including raw material ratio, mixing, reaction and filling. In these processes, the solvent and raw materials in the glue will volatilize due to factors such as temperature increase, pressure change and stirring, resulting in the production process of volatile organic compounds, odor components and particulate matter and other waste gases and wastes. It is necessary to treat the waste gas produced in the glue production process through a waste gas treatment device. For example, the environmentally friendly waste gas treatment device for glue processing disclosed in application number CN202311142581.8 and its use method provide a device that uses multi-stage filtration to make its waste gas treatment effect more timely and effective.

[0003] The prior art targets waste gas from the glue production process, wherein waste gas is treated by activated carbon adsorption, spray tower, catalytic combustion and biofilter to meet the emission standards. When waste gas is treated by spray tower, the waste gas is first introduced into the spray tower, and the liquid sprayed in the tower (usually water or a solution containing a chemical absorbent) is used to contact the waste gas, thereby absorbing or neutralizing the harmful substances in the waste gas. The waste gas usually flows in a gaseous state in the spray tower, and the sprayed liquid exists in the form of droplets or liquid film. Since the contact area between the gas and liquid phases is limited, and the flow path of the waste gas in the tower may be affected by various factors such as the tower structure and the liquid spraying method, some harmful substances in the waste gas cannot fully contact with the liquid, and thus cannot be completely absorbed or neutralized, resulting in low waste gas treatment efficiency. Since the liquid in the spray tower cannot fully contact with the harmful substances in the waste gas, its treatment effect is also greatly reduced. Summary of the invention

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] 1.

Due to the increase in electromagnetic strength, the magnetorheological fluid increases the bonding strength between the main shaft and the slave shaft, thereby increasing the rotation speed of the slave shaft and the adjustment column. After the rotation speed of the adjustment column increases, the adjustment column accelerates the up and down reciprocating movement of the punch rod through the adjustment groove and the adjustment ball, thereby accelerating the speed at which the waste gas above the support plate enters the treatment liquid through the air pipe and the connecting pipe, and the impact force of the waste gas entering the treatment liquid through the air pipe increases, so that the waste gas to be treated can not only be surrounded and fully contacted by the treatment liquid, but also accelerate the reaction speed of the treatment liquid and the waste gas, thereby improving the purification efficiency of the treatment liquid on the waste gas;

[0018] 2. After reacting in the treatment liquid, high-concentration exhaust gas enters the space between the support plate and the air-permeable plate through the air-permeable plate. At this time, the rotating shaft drives the stirring rod to rotate through the missing gear and the stirring gear to stir the activated carbon particles so that they are in full contact with the exhaust gas. The stirring rod can rotate in the opposite direction under the action of the torsion spring. The full contact between the activated carbon particles and the exhaust gas further purifies the low-concentration exhaust gas, thereby improving the compliance rate of the exhaust gas emissions after treatment.

DETAILED DESCRIPTION

[0028] 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. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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.

[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] Example: Refer to Figures 1 to 7, an environmentally friendly waste gas treatment device for glue processing, including a controller, a treatment barrel 1 and a driving assembly 2 arranged on the treatment barrel 1, a filter plate 4 is fixedly installed on the inner wall of the treatment barrel 1, and an air stamping assembly 5 is arranged inside the treatment barrel 1 and below the filter plate 4;

[0031] The gas stamping assembly 5 includes a support plate 51 fixedly mounted on the inner wall of the processing barrel 1, an adjusting column 52 is rotatably mounted on the top of the support plate 51, and an adjusting groove 53 connected end to end and in a wave shape is provided on the outer wall of the adjusting column 52. A support ring 54 is fixedly mounted on the top wall of the support plate 51, and a plurality of limiting slide grooves 55 arranged in a circular array are provided on the support ring 54. A stamping rod 56 is slidably connected to the inner limit position of the limiting slide groove 55. An adjusting ball 531 adapted to the adjusting groove 53 is rotatably mounted on one end of the stamping rod 56 close to the adjusting column 52. A connecting pipe 571 is fixedly installed on the wall, and one end of the connecting pipe 571 close to the adjusting column 52 is fixedly connected to a punching pipe 57 that is slidably connected to the punching rod 56, and the punching pipe 57 is vertically arranged. An air delivery pipe 58 that is respectively connected to each connecting pipe 571 is fixedly installed on the support plate 51. A groove 59 is opened at one end of the punching rod 56 close to the adjusting column 52. The diameter of the groove 59 is the same as the diameter of the opening of the adjusting groove 53. The diameter of the adjusting ball 531 is the same as the inner diameter of the adjusting groove 53, and the inner diameter of the adjusting groove 53 is larger than the diameter of the opening of the groove 59.

[0032] The top of the treatment barrel 1 is provided with an adjustment component 3 for changing the rotation speed of the adjustment column 52. The inner bottom of the treatment barrel 1 stores a treatment liquid for absorbing waste gas. The other end of the gas delivery pipe 58 is connected to the treatment barrel 1 and immersed below the liquid surface of the treatment liquid. Two one-way valves are fixedly installed on the inner wall of the gas delivery pipe 58, and the two one-way valves are respectively placed above and below the connecting pipe 571.

[0033] After the waste gas generated during glue production is introduced into the processing barrel 1 from the top wall of the processing barrel 1, the particulate matter in the waste gas will be trapped on the upper surface of the filter plate 4 when the waste gas is coarsely filtered through the filter plate 4, and the gas flows downward to the space formed between the filter plate 4 and the support plate 51. At the same time, under the action of the driving component 2, the adjusting column 52 rotates and slides through the adjusting groove 53 and the limiting sliding of the adjusting ball 531, so that the punching rod 56 moves back and forth up and down in the limiting sliding groove 55, and the end of the punching rod 56 close to the punching tube 57 moves back and forth up and down in the punching tube 57, and because the diameter of the adjusting ball 531 is the same as the inner diameter of the adjusting groove 53, and the diameter of the groove 59 is the same as the diameter of the opening of the adjusting groove 53, the adjusting ball 531 will not slide out of the adjusting groove 53 when it rotates in the adjusting groove 53, and when the punching rod 56 slides upward, the upper part of the support plate 51 The exhaust gas enters the connecting pipe 571 through the top opening of the air pipe 58, and under the action of the one-way valve, the bottom opening of the air pipe 58 will not suck in the treatment liquid, and when the punching rod 56 moves downward, the exhaust gas in the connecting pipe 571 is pressed into the treatment liquid through the air pipe 58, so that the treatment liquid wraps the exhaust gas, making the treatment liquid and the exhaust gas completely in contact, and the treatment is more thorough. Under the action of the adjusting component 3, the rotation speed of the adjusting column 52 can increase with the increase of the volume of the exhaust gas entering the treatment barrel 1, thereby increasing the speed at which the exhaust gas enters the treatment liquid through the connecting pipe 571 and the air pipe 58, so that the treatment liquid speeds up the exhaust gas treatment, and the exhaust gas after reacting with the treatment liquid flows to the activated carbon particles. Under the action of the stirring component 6, the activated carbon particles are stirred to make them react with the exhaust gas more thoroughly, so as to further purify the exhaust gas.

[0034] Specifically, refer to Figure 2 and Figure 3 The driving assembly 2 includes a driving motor 21 fixedly mounted on the top wall of the processing barrel 1, the output end of the driving motor 21 movably penetrates the top wall of the processing barrel 1 and is fixedly connected to the main rotating shaft 22, the bottom end of the main rotating shaft 22 is fixedly connected to the magnetorheological fluid coupling 23, the output end of the magnetorheological fluid coupling 23 is fixedly connected to the slave rotating shaft 24, and the slave rotating shaft 24 is fixedly connected to the adjusting column 52; the driving motor 21 can drive the main rotating shaft 22 to rotate, and the main rotating shaft 22 then drives the slave rotating shaft 24 to rotate through the magnetorheological fluid coupling 23.

[0035] Further, see Figure 4 and Figure 5The regulating component 3 includes an air inlet pipe 31 fixedly mounted on the top wall of the processing barrel 1, and the air inlet pipe 31 is connected to the waste gas discharge pipe of the glue production equipment through an air pump. The waste gas discharge pipe of the glue production equipment is provided with an electrochemical sensor, and the electrochemical sensor is electrically connected to the controller. A connecting shaft 32 is rotatably mounted on the side wall of the air inlet pipe 31, and an impeller 33 is fixedly mounted on one end of the connecting shaft 32 placed inside the air inlet pipe 31, and a connecting rod 34 is hinged at an eccentric position at one end of the connecting shaft 32 away from the impeller 33. A piston cylinder 35 is fixedly mounted on the top of the processing barrel 1, and a piston 36 is slidably connected to the inner wall of the piston cylinder 35. The end of the connecting rod 34 away from the connecting shaft 32 is hinged to the piston 36, and a circular plate 37 is fixedly mounted inside the piston cylinder 35 and on one side of the piston 36. A sliding rheostat is provided in the inner wall of the piston cylinder 35, and the sliding rheostat includes a circular Slide 38, the circular slide 38 is arranged inside the piston cylinder 35 and on the side of the circular plate 37 away from the piston 36, a spring 39 is fixedly installed on the side of the circular slide 38 away from the circular plate 37, one end of the spring 39 away from the circular slide 38 is fixedly connected to the inner wall of the piston cylinder 35, and an electromagnetic valve is arranged on the end of the spring 39 away from the connecting rod 34. An air inlet hole 371 that can only intake air in the direction of the circular slide 38 is arranged on the circular plate 37, and an air inlet valve that can only intake air in the direction of the circular slide 38 is arranged in the air inlet hole 371. An air outlet hole 351 that can only exhaust air in one direction is opened on the side wall of the piston cylinder 35, and the inner diameter of the air inlet hole 371 is larger than the inner diameter of the air outlet hole 351. The circular slide 38 and the magnetorheological fluid coupling 23 are electrically connected to a DC power supply and constitute a transmission ratio circuit. When the circular slide 38 slides in the direction of the circular plate 37, the resistance of the sliding rheostat in the transmission ratio circuit increases;When the waste gas generated during glue production is pumped into the processing barrel 1 through the air inlet pipe 31 by the air pump, when the waste gas concentration is low, the air pump operating power is low, and the impeller 33 does not rotate. When the electrochemical sensor detects that the waste gas concentration is high, the electrochemical sensor transmits an electrical signal to the controller, and the controller converts the electrical signal into a control signal for the air pump, so that the operating power of the air pump increases, thereby causing the impeller 33 to rotate. When the impeller 33 rotates, the connecting rod 34 is driven to reciprocate through the connecting shaft 32, and the connecting rod 34 drives the piston 36 to slide to pass the gas between the piston 36 and the circular plate 37 through the inlet pipe 31. The air hole 371 is pressed into between the circular plate 37 and the circular slide 38, and the gas pressed into between the circular plate 37 and the circular slide 38 through the air inlet hole 371 will flow out through the air outlet hole 351. Since the inner diameter of the air inlet hole 371 is larger than the inner diameter of the air outlet hole 351, the amount of air entering between the circular plate 37 and the circular slide 38 through the air inlet hole 371 per unit time is greater than the amount of air flowing out between the circular plate 37 and the circular slide 38 through the air outlet hole 351, thereby forming a stable air flow difference between the circular plate 37 and the circular slide 38. However, as the rotation speed of the impeller 33 increases, the amount of gas entering also increases. The gas entering between the circular plate 37 and the circular slide 38 cannot be completely discharged through the air outlet 351 in time, thereby increasing the air pressure between the circular plate 37 and the circular slide 38, that is, squeezing the circular slide 38 so that the circular slide 38 slides inside the piston cylinder 35, and the spring 39 is also compressed, and the effective resistance of the corresponding sliding rheostat is reduced, and the current is increased, resulting in an increase in the electromagnetic field strength, thereby affecting the state of the magnetorheological fluid inside the magnetorheological fluid coupling 23, that is, the viscosity of the magnetorheological fluid increases due to the increase in electromagnetic intensity, thereby increasing the pressure between the main shaft 22 and the slave shaft 24. The combination strength is increased, thereby increasing the rotation speed of the slave shaft 24 and the adjusting column 52. When the exhaust gas concentration is low, the air pump operates at a low power, so that the impeller 33 no longer rotates or the rotation speed is low. The gas entering between the circular plate 37 and the circular slide 38 can flow out through the outlet hole 351 in a timely and complete manner. The circular slide 38 slides toward the circular plate 37 under the action of the elastic force of the spring 39, and the effective resistance of the corresponding sliding rheostat increases, the current decreases, the electromagnetic field strength decreases, the viscosity of the magnetorheological fluid decreases, the combination strength between the main shaft 22 and the slave shaft 24 decreases, and the rotation speed of the slave shaft 24 decreases. ;
