DETAILED DESCRIPTION
[0024] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only 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.
[0025] See also Figure 1-7The present invention provides a technical solution: a VOCs waste gas treatment device for masterbatch production, comprising a waste gas collection chamber, a pretreatment mechanism, a waste gas treatment mechanism and a discharge chamber, a pump is arranged inside the waste gas collection chamber, the pretreatment mechanism is arranged in the waste gas collection chamber, the pretreatment mechanism comprises a dust removal system, a cooling system and a dehumidification system, the dust removal system is used for preliminary dust removal of the waste gas, the cooling system is used for cooling the waste gas, and the dehumidification system is used for dehumidifying the waste gas;
[0026] The waste gas treatment mechanism includes a treatment chamber 1, and an adsorption mechanism, a regeneration mechanism, and a laser dust monitor are arranged inside the treatment chamber 1. The treatment chamber 1 is connected to the waste gas collection chamber pipeline, and the treatment chamber 1 is connected to the discharge chamber pipeline. The adsorption mechanism includes a molecular sieve 2, and the molecular sieve 2 and the laser dust monitor are fixedly installed inside the treatment chamber 1. The regeneration mechanism includes an air gun 3, a baffle 4, a pin 5, and a lifting mechanism. The air gun 3 bearing is installed on the inner wall of the treatment chamber 1, and is connected to the external air pump pipeline, and is located on the right side of the molecular sieve 2. The baffle 4 is connected to the lower part of the inner wall of the treatment chamber 1 through the pin 5, and is located on the left side of the molecular sieve 2. A placement groove 6 is opened at the bottom of the inner wall of the treatment chamber 1, and the lifting mechanism is located inside the placement groove 6 and below the baffle 4. A motor 7 is fixedly installed on one side of the treatment chamber 1, and the air gun 3 is fixedly connected to the output end of the motor 7. A partition 8 is fixedly installed in the middle of the placement groove 6;
[0027] The VOCs waste gas treatment device also includes an optimization control system, which is electrically connected to the pump, the dust removal system, the cooling system and the dehumidification system respectively;
[0028] The operation of the optimization control system is controlled to control the operation of the pump. The pump extracts the waste gas and injects it into the waste gas collection chamber. Then the dust removal system, the cooling system and the dehumidification system are controlled to operate to pre-treat the waste gas, perform dust removal, dehumidification and cooling work, and then the pump is controlled to operate to inject the pre-treated waste gas into the processing chamber 1 through the pipeline. The waste gas passes through the molecular sieve 2, and the molecular sieve 2 adsorbs the particulate matter in the waste gas. The treated waste gas enters the discharge chamber through the pipeline and is discharged from the discharge chamber, which plays a role in quickly, automatically and efficiently cleaning the waste gas;
[0029] After a period of waste gas treatment, there are many particles adsorbed on the molecular sieve 2. At this time, the motor 7 is running, driving the air gun 3 to rotate, and the external air pump is running at the same time. The air gun 3 blows air from bottom to top at the molecular sieve 2 to blow off the particles adsorbed on the left side of the molecular sieve 2, so that the molecular sieve 2 can be repeatedly regenerated and used to reduce costs.
[0030] The lifting mechanism includes a telescopic top rod 61, a hydraulic chamber 62, a connecting rod 63, and a toothed plate 64. A toothed plate 31 is fixedly mounted at the center of the air gun 3;
[0031] The inner wall of the hydraulic chamber 62 is slidably connected with a hydraulic plate 621, the hydraulic chamber 62 is fixedly installed at the bottom of the inner wall of the placement groove 6, the tooth plate 64 is fixedly connected to the right side of the hydraulic plate 621 through the connecting rod 63, and the tooth plate 64 is meshed with the toothed disc 31;
[0032] The telescopic push rod 61 is connected to the left pipeline of the hydraulic chamber 62, the left side of the hydraulic plate 621 is filled with hydraulic oil, and the upper end of the telescopic push rod 61 is in contact with the lower surface of the baffle 4;
[0033] During the rotation of the air gun 3, the toothed disc 31 is driven to rotate around its center, and the toothed disc 31 drives the toothed plate 64 to move to the left through meshing. The toothed plate 64 drives the hydraulic plate 621 to slide to the left along the inner wall of the hydraulic chamber 62 through the connecting rod 63. The liquid on the left side of the hydraulic plate 621 is squeezed and enters the telescopic push rod 61 through the pipeline to extend it. The upper end of the telescopic push rod 61 supports the lower surface of the baffle 4, so that the baffle 4 rotates through the pin 5 and is lifted. As the blowing angle of the air gun 3 changes, the baffle 4 gradually rises, so that the baffle 4 can always block the particles. The particles are blown off and blocked by the baffle 4, and then fall to the bottom of the processing chamber 1, which is convenient for the subsequent collection of the particles. After the cleaning work of the molecular sieve 2 is completed, the motor 7 is reset, thereby resetting the hydraulic plate 621, and the liquid in the telescopic push rod 61 is extracted through the pipeline to reset it. The baffle 4 is reset under the influence of its own gravity.
[0034] A telescopic rod 111 is fixedly installed on the inner wall of the processing chamber 1, and an elastic spring 112 is fixedly installed on the lower end of the telescopic rod 111. A brush rod 113 is fixedly installed on the lower end of the elastic spring 112. The outer surface of the brush rod 113 is provided with a plurality of bristles and is in contact with the left side of the molecular sieve 2;
[0035] The right side of the hydraulic chamber 62 is connected to the telescopic rod 111 with two pipes, and pressure valves are arranged in the two pipes, and the gas flow directions of the two pressure valves are opposite;
[0036] Through the above steps, when the hydraulic plate 621 slides left and right along the inner wall of the hydraulic chamber 62, when the air gun 3 rotates to the limit distance, the blowing work is completed. At this time, the negative pressure generated on the right side of the hydraulic plate 621 reaches the bearing limit of the pressure valve, thereby extracting the gas in the telescopic rod 111, causing the telescopic rod 111 to shorten rapidly. The hydraulic plate 621 is reset, causing the telescopic rod 111 to extend rapidly. The rapid shortening of the telescopic rod 111 drives the elastic spring 112 to move upward rapidly, thereby driving the brush rod 113 to move upward rapidly, so that the bristles of the brush rod 113 roll and brush the left side of the molecular sieve 2, thereby further improving the cleaning effect of the molecular sieve 2 and improving the adsorption capacity of the molecular sieve 2. The telescopic rod 111 quickly retracts and reciprocates, and rolls and brushes the left side of the molecular sieve 2 reciprocatingly, thereby greatly improving the cleaning effect.
[0037] A fixing block 65 is fixedly installed at the bottom of the inner wall of the placement groove 6, a slide groove 651 is arranged in the middle of the fixing block 65, and a through hole 652 is arranged at the bottom, and the slide groove 651 and the through hole 652 are communicated with each other;
[0038] The inner wall of the slide groove 651 is slidably connected with a slider 653, the bottom of the slider 653 is fixedly installed with an arc block 654, the inner wall of the through hole 652 is slidably connected with a ball 655, the ball 655 is connected to the left spring of the inner wall of the through hole 652, and the initial position of the ball 655 is located at the bottom of the arc block 654, and they fit each other;
[0039] The slider 653 is fixedly connected to the bottom end of the telescopic top rod 61, a push rod 656 is fixedly installed on the right side of the sphere 655, and an extrusion rod 641 is fixedly installed on the left side of the tooth plate 64. The lower end of the extrusion rod 641 and the right end of the push rod 656 are both spherical and aligned with each other.
[0040] When the tooth plate 64 moves to the left, it drives the squeezing rod 641 to move to the left, and the lower end of the squeezing rod 641 and the right end of the push rod 656 squeeze each other. The push rod 656 is subjected to force to make the ball 655 slide to the left along the inner wall of the through hole 652, and the spring is deformed under the force. When the push rod 656 moves to the limit position, the reaction force generated by the spring is large, and the push rod 656 and the squeezing rod 641 slip, so that they are staggered with each other. At this time, the spring generates a reaction force to push the ball 655 to reset quickly, and the ball 655 hits the arc block 654, so that the slider 653 slides quickly upward along the slide groove 651, and the telescopic top rod 61 hits the bottom of the baffle 4 quickly, so that the baffle 4 shakes and vibrates, which can shake off the particles blocked on the surface, so that the particles can be fully collected later.
[0041] An arc-shaped rod 41 is fixedly mounted on the upper surface of the baffle 4, and the upper end of the arc-shaped rod 41 is spherical;
[0042] Through the above steps, when the baffle 4 rotates, the arc rod 41 is driven to rotate around the center of the pin shaft 5 until it contacts the elastic spring 112. When the baffle 4 is hit by the telescopic top rod 61 and shakes and vibrates, the arc rod 41 squeezes the elastic spring 112, pressing the elastic spring 112 to the right until it is deformed, thereby driving the brush rod 113 to squeeze the left side of the molecular sieve 2 to the right, thereby increasing the fitting strength between the brush rod 113 and the molecular sieve 2. When the telescopic rod 111 is quickly reset, the force of the rolling brush on the side of the molecular sieve 2 is increased, the cleaning effect is enhanced, and the residual particles on the molecular sieve 2 can be fully brushed off.
[0043] The optimization control system includes a particle detection module, an angle control module, a speed control module, and a power control module. The particle detection module is arranged inside the laser dust monitor and is electrically connected to the angle control module, the speed control module, and the power control module respectively.
[0044] The particle detection module is used to detect the particle concentration in the exhaust gas through a laser dust meter, the angle control module is used to control the rotation angle change of the motor 7, the speed control module is used to control the speed of the motor 7 according to the particle concentration in the exhaust gas, and the power control module is used to control the power of the external air pump according to the particle concentration in the exhaust gas.
[0045] The operation process of the VOCs waste gas treatment device includes:
[0046] Step S1, optimizing the control system operation, controlling the pump operation, the pump extracts the exhaust gas and injects it into the exhaust gas collection chamber, and then controlling the dust removal system, the cooling system and the dehumidification system to operate, pre-treat the exhaust gas, and perform dust removal, dehumidification and cooling operations;
[0047] Step S2, the control system controls the pump to inject the pre-treated waste gas into the processing chamber 1 through the pipeline, and the waste gas passes through the molecular sieve 2, and the molecular sieve 2 adsorbs the particulate matter in the waste gas;
[0048] Step S3, after the exhaust gas is treated for a period of time, the optimization control system drives the motor 7 and the external air pump to operate, and the concentration of particulate matter in the exhaust gas is detected by a laser dust meter. The rotation angle of the motor 7 is controlled according to the concentration of particulate matter in the exhaust gas, and the rotation angle is controlled. The speed of the rotation angle change is controlled, and the operating power of the external air pump is controlled at the same time to blow off the particulate matter on the molecular sieve 2;
[0049] Step S4: After that, the completely treated waste gas enters the discharge chamber through the pipeline and is discharged from the discharge chamber.
[0050] In step S3, the higher the concentration of particulate matter in the exhaust gas, the slower the speed at which the angle of the motor 7 changes, and the higher the initial power of the external air pump, and the power of the external air pump gradually increases as the rotation angle of the motor 7 changes;
[0051] In view of the small amount of particulate matter in the exhaust gas, the molecular sieve 2 screens out small amount of particulate matter, thereby accelerating the angle change speed of the motor 7, ensuring the cleaning of the molecular sieve 2 and accelerating the cleaning speed, so that the molecular sieve 2 can always maintain fluidity, and the molecular sieve 2 can be repeatedly regenerated and used. At the same time, the initial operating power of the external air pump is low, which can blow the particulate matter off the molecular sieve 2 and reduce energy consumption, saving costs;
[0052] In view of the large number of particles in the exhaust gas, the molecular sieve 2 screens out a large number of particles, thereby reducing the angle change speed of the motor 7 and increasing the initial operating power of the external air pump, which can strengthen the blowing force on the molecular sieve 2, and slowly and strongly blow air from bottom to top on the molecular sieve 2, so that the particles on the molecular sieve 2 can be fully blown off;
[0053] As the angle of the air gun 3 changes, the distance between the air gun 3 and the molecular sieve 2 increases, so that the operating power of the external air pump gradually increases, thereby preventing the particles above the molecular sieve 2 from being fully blown off.
