Description

Technical Field

[0001] The present invention relates to the technical field of waste gas absorption treatment, and in particular to a waste gas absorption treatment device and method generated by black medicine preparation. Background Art

[0002] Black medicine is widely used in sulfur ore flotation, second only to yellow medicine as a collector. It has been used since 1925. Its chemical name is dialkyl thiophosphate, which is divided into two categories: dialkyl dithiophosphate and dialkyl monothiophosphate.

[0003] At present, a large amount of waste gas is often generated in the process of black medicine preparation. These waste gases are often hydrogen sulfide, ammonia and various organic waste gases. The current treatment method for this type of waste gas is often through spraying and adsorption. However, when the current spray head sprays multiple arc-surface trajectories of spray liquid all around, there are still gaps between the multiple arc-surface trajectories of the spray liquid, which causes some waste gas to escape. After the adsorption material is saturated with impurities in the waste gas, the cleaning liquid and the adsorption material are contacted by flushing to complete the decomposition and cleaning of the impurities. At present, the adsorption material is often laid horizontally in the filter box, which shortens the contact time between the flushing liquid and the adsorption material and reduces the cleaning efficiency. Summary of the invention

[0015] A method for preparing a waste gas absorption treatment device using black medicine comprises the following steps:

[0016] S1, introducing the waste gas generated by the black powder preparation from the air inlet pipe;

[0017] S2. Turn on the motor to spray the treatment liquid from the spray head to treat the exhaust gas, and the adsorption material (such as activated carbon particles) filled in the filter box adsorbs the exhaust gas;

[0018] S3, energize the electromagnet device and restart the motor for a period of time, so that the external flushing liquid can flush the filter box in a vertically upward state through multiple flushing nozzles.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. By setting up structures such as a motor, a circular plate and a circular frame, the circular frame is made to reciprocate in the horizontal direction, and then the external treatment liquid is continuously sprayed from the spray head to spray the exhaust gas through structures such as a driving rod, a sliding plug and a driving box;

[0021] 2. In the above process, the worm also drives the cylinder to rotate synchronously through the telescopic universal coupling, and the cylinder drives the spray head to rotate synchronously. During the self-rotation process of the spray head, the sprayed treatment liquid can be more evenly covered to a larger area, thereby improving the spraying efficiency;

[0022] 3. In the above process, the circular frame will also drive the circular ring block fixed to it to reciprocate synchronously, so that the circular ring block drives the cylinder and the sprinkler head to reciprocate synchronously. Then the sprinkler head will also move continuously, and the sprinkler head can ensure that every position inside the inverted convex box can be sprayed evenly, avoiding the spraying dead angle that may appear in the fixed sprinkler head, and enhancing the spraying effect;

[0023] 4. When the waste gas after spraying treatment passes through multiple filter boxes, the multiple filter boxes are sealed by sealing strips. Then the adsorption material (such as activated carbon particles) filled inside the filter box will absorb the impurities in the waste gas, further improving the treatment capacity of the waste gas generated in the black medicine preparation process;

[0024] 5. After the adsorption material (such as activated carbon particles) is saturated with adsorption, the electromagnet device is energized, and the motor is turned on for a period of time. Under the action of multiple conical wheels, rotating rods and switching rods, the filter box is rotated 90 degrees to a vertically upward state, and multiple flushing nozzles are used to flush the filter box in the vertically upward state. The flushing liquid will experience a longer cleaning time inside the filter box in the vertically upward state, thereby improving the cleaning effect of the adsorption material.

[0041] A motor 2 is fixedly installed on the side wall of the inverted convex box 1, a main shaft 3 is fixedly installed on the output end of the motor 2, the main shaft 3 passes through the side wall of the inverted convex box 1 and is fixedly connected to a first bevel gear 26, a second bevel gear 27 is fixedly connected to the side wall of the worm 6, and the first bevel gear 26 and the second bevel gear 27 are meshingly connected.

[0042] Each filter box 35 has a sealing strip symmetrically installed on its side wall, and an isolation net 37 symmetrically installed on the inner wall of the filter box 35 to prevent the adsorbed material (such as activated carbon particles) inside the filter box 35 from falling from the switching hole 36. A plurality of flushing nozzles 39 are installed on the inner wall at the top of the inverted convex box 1, a plurality of air outlet pipes 40 are fixedly penetrated through the top wall of the inverted convex box 1, an air inlet pipe 41 is fixedly penetrated through the bottom wall of the inverted convex box 1, the worm gear 4 and the worm 6 are meshingly connected, and the first conical wheel 28 and the second conical wheel 29 are meshingly connected.

[0043] A method for preparing a waste gas absorption treatment device using black medicine comprises the following steps:

[0044] S1, introducing the waste gas produced by the black powder preparation from the air inlet pipe 41;

[0045] S2, turning on the motor 2, so that the treatment liquid is sprayed from the spray head 19 to spray the exhaust gas, and the adsorption material (such as activated carbon particles) filled in the filter box 35 adsorbs the exhaust gas;

[0046] S3, energize the electromagnet device 51, and restart the motor 2 for a period of time, so that the external flushing liquid can flush the filter box 35 in a vertically upward state through the multiple flushing nozzles 39.

[0047] In the present invention, the user turns on the motor 2 and fixes the end of the first one-way tube 24 away from the drive box 20 to a storage box containing treatment liquid outside, and then the waste gas generated during the black medicine preparation process enters the inside of the inverted convex box 1 through the air intake pipe 41.

[0048] After the motor 2 is started, the output end of the motor 2 will drive the main shaft 3 fixedly connected thereto to rotate, and the main shaft 3 will drive the main shaft 3 fixedly connected thereto to rotate, and the main shaft 3 will drive the worm 6 to rotate through the first bevel gear 26 and the second bevel gear 27. Since the worm 6 and the worm wheel 4 are meshingly connected, the worm 6 will drive the worm wheel 4 to rotate, and the worm wheel 4 will drive the circular plate 7 to rotate, and then the slide bar 11 will slide inside the annular groove 8 opened on the side wall of the circular plate 7. Since the circular plate 7 and the rotating shaft 52 are eccentrically fixed, when the slide bar 11 slides inside the annular groove 8, it will drive the round rod 9 to rotate forward and reversely by a certain angle through the upper connecting rod 10, and then the round rod 9 will drive the circular frame 14 to reciprocate for a certain distance in the horizontal direction through the lower connecting rod 12 and the pushing plate 13. The circular frame 14 contacts the driving rod 22 on the left side during the left sliding process, and then drives the driving rod 22 It drives the sliding plug 21 fixedly connected to it to slide to the left in a sealed manner for a distance, and then squeezes the treatment liquid inside the driving box 20 into the annular groove 49 for circulation through the second one-way tube 25, and then these treatment liquids enter the cylinder 17 through the flow holes 18 opened on the side wall of the cylinder 17 for circulation, and finally are sprayed out from the spray head 19 to spray the exhaust gas. When the circular frame 14 slides to the right, the circular frame 14 will contact the driving rod 22 on the right side, and then squeeze the treatment liquid inside the driving box 20 on the right side to the spray head 19 for spraying to treat impurities such as hydrogen sulfide and ammonia in the exhaust gas, and the tension spring 23 arranged inside the driving box 20 on the left side will push the corresponding sliding plug 21 to slide in the reverse sealing manner, and draw the external treatment liquid in through the first one-way tube 24 for replenishment, and be used for subsequent spraying.

[0049] During the rotation of the worm 6, the worm 6 drives the cylinder 17 to rotate synchronously through the telescopic universal coupling 48, and the cylinder 17 drives the spray head 19 to rotate synchronously. During the rotation of the spray head 19, the sprayed treatment liquid can be more evenly covered to a larger area, thereby improving the spraying efficiency.

[0050] In the above process, the circular frame 14 will also drive the circular ring block 16 fixedly connected thereto to reciprocate synchronously, so that the circular ring block 16 drives the cylinder 17 and the spray head 19 to reciprocate synchronously. Then the spray head 19 will also continuously move, and then the spray head 19 can ensure that each position inside the inverted convex box 1 can be sprayed evenly, avoiding the spray dead angle that may appear in the fixed spray head 19, and enhancing the spray effect.

[0051] When the waste gas treated by spraying passes through multiple filter boxes 35 again, the multiple filter boxes 35 are sealed by sealing strips. Then, the adsorption material (such as activated carbon particles) filled inside the filter box 35 will absorb the impurities in the waste gas, further improving the treatment capacity of the waste gas generated in the black medicine preparation process. After the adsorption material (such as activated carbon particles) is saturated with adsorption, it needs to be cleaned. At this time, the electromagnet device 51 is energized. The energized electromagnet device 51 and the magnetic plug rod 45 have opposite polarities and magnetic repulsion to each other. Then, the magnetic plug rod 45 will slide outward from the inside of the circular groove 43 for a distance until one end of the magnetic plug rod 45 is inserted into the inside of the slot 42, completing the limiting of the first conical wheel 28 and the worm 6.

[0052] At this time, the motor 2 is turned on for a period of time, so that the worm 6 will drive the first conical wheel 28 to rotate a certain angle during the rotation process, and the first conical wheel 28 will drive the rotating rod 47 to rotate a certain angle. The rotating rod 47 drives the cross bar 32 to move through the first rod 30, so that the cross bar 32 drives the switching rods 38 connected to it for rotation. Then, each switching rod 38 drives the circular shaft 34 fixedly connected thereto to rotate a certain angle, until each circular shaft 34 drives the filter box 35 fixedly connected thereto to rotate ninety degrees, so that the filter box 35 is in a vertically upward state. At this time, multiple flushing nozzles 39 are turned on, so that the external flushing liquid passes through the multiple flushing nozzles 39 to flush the filter box 35 in the vertically upward state. The flushing liquid will experience a longer cleaning time inside the filter box 35 in the vertically upward state, avoiding the cleaning method in the prior art that the flushing cleaning liquid and the adsorption material (such as activated carbon particles) are immediately separated after just contacting, thereby improving the cleaning effect of the adsorption material (such as activated carbon particles).

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
