Example

[0022] Reference Figure 1-Figure 8 A method for removing benzene series from petrochemical industrial waste gas comprises a base 1 with a cavity, and also comprises: a working cylinder 2, fixedly connected to the top of the base 1, wherein a partition plate 5 is provided on the inner wall of the working cylinder 2, and the partition plate 5 is provided to separate an upper cavity and a lower cavity, and an adsorption mechanism is provided in the lower cavity; an adjusting disk 12, which is lifted and lowered in the upper cavity, wherein a reciprocating mechanism is provided on the adjusting disk 12, and a spray plate 15 is provided on the moving end of the reciprocating mechanism, and the spray end of the spray plate 15 faces the partition plate 5; a purification cylinder 30, fixedly connected to the top of the base 1, wherein a two-way hybrid mechanism is provided in the purification cylinder 30, an exhaust pipe 35 is fixedly connected to the bottom of the purification cylinder 30, and the exhaust pipe 35 is communicated with the working cylinder 2, an exhaust hole 36 is opened on the exhaust pipe 35, and the exhaust hole 36 faces the two-way hybrid mechanism.

[0023] The benzene series waste gas generated in the petrochemical industry is transported to the working cylinder 2 through a pipeline after pretreatment. The pretreatment mainly removes impurities such as particulate matter and moisture in the benzene-containing waste gas by filtering, cooling, dehumidifying, etc. to protect subsequent processing equipment.

[0024] In addition, a liquid storage cavity is provided in the base 1 for storing absorbents. The absorbents usually use the following two types: organic solvents: including alcohols (such as ethanol, isopropanol), ethers, ketones and aromatic hydrocarbons. Chemical solutions: certain chemical solutions (such as alkaline solutions such as sodium hydroxide and potassium hydroxide), where the organic solvent has a high solubility for benzene substances, which can effectively improve the absorption efficiency. Chemical solutions can absorb benzene substances through chemical reactions to achieve more efficient purification. The absorbent can be selected according to the concentration adaptability of the benzene gas, and the spray plate 15 will spray the absorbent into the upper cavity in the form of mist.

[0025] The gas containing benzene will first move from the bottom of the working cylinder 2 into the lower cavity, and then cooperate with the adsorption end of the adsorption mechanism. The adsorption mechanism includes an activated carbon adsorption disk 4 detachably arranged in the lower cavity, and the outer portion of the activated carbon adsorption disk 4 is in contact with the inner wall of the working cylinder 2.

[0026] The activated carbon adsorption disk 4 can be used to preliminarily adsorb the gas containing benzene, and the activated carbon has a very large specific surface area and a porous structure, which enables it to effectively adsorb a large amount of benzene substances in the gas, thereby improving the adsorption capacity of the device.

[0027] In addition, an outlet pipe 6 is fixedly connected to the partition plate 5, and a one-way valve is provided on the outlet pipe 6. The gas adsorbed by the activated carbon adsorption disk 4 will be transported to the upper cavity through the outlet pipe 6. At this time, the adjustment disk 12 will drive the spray plate 15 to move up and down reciprocatingly, so that the absorbent sprayed from the spray plate 15 moves synchronously.

[0028] Here, the spray plate 15 can move back and forth while reciprocating up and down. By lifting up and down and moving forward and backward, the spray plate 15 can achieve a uniform spraying effect in the entire working cylinder 2, ensuring that the absorbent can cover every area, reducing dead angles, and improving absorption efficiency. In addition, multi-directional spraying can greatly enhance the contact opportunity between benzene exhaust gas and absorbent, increase reaction time, and allow benzene to fully dissolve in the absorbent.

[0029] Furthermore, the reciprocating mechanism includes: a movable block 17 fixedly connected to the spray plate 15, wherein a slide groove 13 is provided on the adjusting disk 12, a limit plate 14 is fixedly connected to the slide groove 13, the movable block 17 is slidably connected to the slide groove 13 and fits with the inner wall of the limit plate 14; a rotating shaft 19 rotatably connected to the adjusting disk 12, wherein a first crank 21 is rotatably connected to the rotating shaft 19, a second crank 22 is rotatably connected to the first crank 21, and the connecting end of the second crank 22 is rotatably connected to the movable block 17.

[0030] A transmission disk 18 is fixedly connected to the adjusting disk 12, a rotating shaft 19 extends into the transmission disk 18 and is fixedly connected to a turbine blade 20, a water pump 29 is fixedly connected to the base 1, one side of the transmission disk 18 is connected to the output end of the water pump 29 through a pipeline, and the other side of the transmission disk 18 is connected to the spray plate 15 through a pipeline.

[0031] When the water pump 29 pressurizes and delivers the absorbent in the cavity of the base 1 to the transmission disk 18, during this process, the turbine blade 20 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the first crank 21 to rotate. When the first crank 21 rotates, it can drive the second crank 22 to move, and then the movable block 17 reciprocates on the slide 13. At this time, the spray plate 15 reciprocates at the bottom of the adjustment disk 12, so that the spray holes 16 on the spray plate 15 swing back and forth to spray.

[0032] A support plate 7 is fixedly connected inside the working cylinder 2, and a transmission shaft 8 is rotatably connected to the support plate 7. A threaded groove 10 is opened on the outer wall of the transmission shaft 8, and a lifting block 11 is threadedly connected to the threaded groove 10. An adjusting disk 12 is fixedly connected to the lifting block 11, and a blade 9 is fixedly connected to the top of the transmission shaft 8.

[0033] When the gas in the working cylinder 2 passes through the blades 9, it drives the transmission shaft 8 to rotate, and then the transmission shaft 8 drives the lifting block 11 to move up and down reciprocatingly, and at the same time drives the adjusting disk 12 to move up and down.

[0034] When the water pump 29 is working, the absorbent is conveyed into the spray plate 15 under pressure, and a spray hole 16 is provided on the spray plate 15 . A diversion cavity is provided in the spray plate 15 , and the diversion cavity is communicated with the spray hole 16 .

[0035] After benzene is dissolved in the absorbent, it will be transported to the purification cylinder 30 through the top pipe. An exhaust pipe 35 is fixedly connected to the bottom of the purification cylinder 30, and the exhaust pipe 35 is spirally arranged at the inner bottom of the purification cylinder 30. An exhaust hole 36 is opened on the exhaust pipe 35, and the exhaust hole 36 faces the two-way hybrid mechanism.

[0036] The purification cylinder 30 is filled with absorbent, which can be mixed and stirred by a two-way mixing mechanism, and the spiral exhaust holes 36 can disperse the gas at different positions of the purification cylinder 30.

[0037] Furthermore, the above-mentioned two-way hybrid mechanism includes a rotating rod 31 rotatably connected in the purification cylinder 30, wherein a first stirring blade 32 is fixedly connected to the rotating rod 31, a sleeve 33 is rotatably connected to the rotating rod 31, a second stirring blade 34 is fixedly connected to the sleeve 33, and the first stirring blade 32 rotates in the opposite direction to the second stirring blade 34, and the exhaust end of the exhaust hole 36 faces the stirring blade. A motor 40 is fixedly connected in the cavity of the base 1, the bottom of the rotating rod 31 is fixedly connected to the output end of the motor 40, a mounting rod 38 is rotatably connected in the cavity of the base 1, the rotating rod 31 is connected to the mounting rod 38 through a pulley, the sleeve 33 extends into the cavity and is fixedly connected to a main gear 37, an auxiliary gear 39 is fixedly connected to the mounting rod 38, and the main gear 37 is meshed with the auxiliary gear 39.

[0038] When the motor 40 rotates, it will drive the rotating rod 31 to rotate, so that the rotating rod 31 drives the first stirring blade 32 to rotate. When the rotating rod 31 rotates, it can drive the mounting rod 38 to rotate synchronously. At this time, the auxiliary gear 39 will drive the main gear 37 to rotate, so that the mounting rod 38 rotates in the opposite direction to the rotating rod 31, thereby making the rotation direction of the first stirring blade 32 opposite to the shape direction of the second stirring blade 34, and the cross-sectional shape of the second stirring blade 34 is wing-shaped. When the second stirring blade 34 rotates, the absorbent at the end will form a spiral vortex.

[0039] The stirring blades in opposite directions can produce a more complex flow pattern, so that the interaction between the components is more sufficient, the mixing uniformity is improved, and the relative movement can promote the rapid exchange of substances inside the absorbent liquid, thereby accelerating the reaction rate or solubility of benzene and the absorbent. At the same time, the opposite rotation of the two sets of stirring blades can break the dead zones that may exist in the liquid, ensuring that the absorbent liquid in each area of ​​the purification cylinder 30 can be fully stirred.

[0040] In addition, a ring plate 23 is fixedly connected to the adjusting disk 12, a guide cylinder 24 is fixedly connected to the ring plate 23, a guide rod 25 is slidably connected to the guide cylinder 24, a piston is provided at one end of the guide rod 25, and the piston is fitted with the inner wall of the guide cylinder 24, a baffle 26 is fixedly connected to the other end of the guide rod 25, and the baffle 26 is provided at the edge of the ring plate 23, a booster cylinder 27 is fixedly connected to the support plate 7, a booster rod 28 is slidably connected to the booster cylinder 27, a sealing plug is provided at one end of the booster rod 28, and the sealing plug is fitted with the inner wall of the booster cylinder 27, the other end of the booster rod 28 is fixedly connected to the bottom of the adjusting disk 12, and the booster cylinder 27 is connected to the guide cylinder 24 through a pipeline.

[0041] A convex block 3 is fixedly connected to the inner wall of the working cylinder 2 . The convex block 3 is provided with two sets of inclined surfaces, and the two sets of inclined surfaces are coupled and extended to form a cone. The adjusting disk 12 is arranged above the convex block 3 .

[0042] When the adjusting disk 12 moves up and down, the boosting rod 28 will be driven to move synchronously. During this process, the adjusting disk 12 will be limited so that it can only move up and down, and the boosting rod 28 will drive the sealing plug to move, and transport the gas below to the guide cylinder 24 through the pipeline. At this time, the gas in the guide cylinder 24 will push the piston to move, so that the piston drives the guide rod 25 to move, and then the guide rod 25 drives the baffle 26 to move.

[0043] When the adjusting disk 12 moves downward to the upper inclined surface of the protrusion 3, the baffle 26 extends to the outside to block the gap between the adjusting disk 12 and the protrusion 3. When the airflow passes through the gap between the adjusting disk 12 and the protrusion 3, the speed of the airflow will increase, thereby allowing the airflow to be quickly transported to the exhaust pipe 35. When the adjusting disk 12 moves up from the upper inclined surface of the protrusion 3 and is reset, the baffle 26 is reset. At this time, the gap between the adjusting disk 12 and the protrusion 3 is in a normal state, thereby allowing the airflow to be smoothly transported to the exhaust pipe 35. The transported airflow can be in an intermittent pressurized state, and the stirring blades are used to purify the benzene gas, thereby accelerating the reaction rate of the benzene gas during the purification process, thereby further improving the processing efficiency.
