[0002] Activated carbon adsorption equipment is a commonly used environmental protection equipment, which is widely used in the treatment of industrial waste gas.

[0040] refer to Figure 1-8 The method for treating waste gas from ethylene tar oil pools mainly removes pollutants such as particulate matter, gas and vapor in the waste gas by adsorption. The adsorption effect of adsorbents such as activated carbon can be used to adsorb harmful substances in the waste gas on the surface of the adsorbent, thereby achieving the separation and removal of pollutants. Activated carbon has a large specific surface area and good adsorption performance, which can effectively remove pollutants such as organic matter, sulfides and nitrides in the waste gas. Since activated carbon can be recycled, when replacing it, it is necessary to disassemble the activated carbon adsorber first (including the subsequent loading and reinstallation of activated carbon) before further replacement. The overall operation is cumbersome;

[0041] In order to overcome the above-mentioned defects, the present invention designs an ethylene tar oil pool waste gas treatment device.

[0042] Activated carbon suction and filtration method:

[0043] Initially, the purification cylinder 253 on the purification component 25 is filled with activated carbon, and there are four groups of purification cylinders 253. When the ethylene tar oil pool exhaust gas is connected to the air inlet valve 24 of the purification part 2 and enters the purification tank 21 through the air inlet valve 24, the pressure inside the purification tank 21 continues to increase, and then the ethylene tar oil pool exhaust gas is passed into the purification cylinder 253 for purification. The purified air flows into the air storage tank 265 of the exhaust component 26, and then flows into the exhaust pipe 263 through the connecting pipe, and then flows into the telescopic hose 264, the air guide pipe 22, and the exhaust pump 12 in turn, and is finally discharged through the exhaust channel 13.

[0044] Activated carbon replacement method:

[0045] During discharge, a large amount of activated carbon is loaded in the purification cylinder 253. After long-term adsorption, the saturated activated carbon needs to be replaced (recyclable). First, start the lifting unit 262 on the exhaust component 26 to drive the gas storage tank 265, the exhaust pipe 263, and the telescopic hose 264 to move upward synchronously (the telescopic hose 264 undergoes elastic deformation), and drive the first sealing ring 2651, the second sealing ring 2652, and the sealing air guide ring 2653 on the gas storage tank 265 to synchronously detach from the upper end of the baffle plate 254 (the sealing air guide ring 2653 is connected to the exhaust hole 2541, and the bottom end of the first sealing ring 2651 is tightly fitted with the inner wall of the space surrounded by the external circular plate 2543 and the baffle plate 254, and the bottom end of the second sealing ring 2652 is tightly fitted with the inner wall of the space surrounded by the internal circular plate 2544, the shielding plate 254 is tightly fitted to the inner wall of the space enclosed), then the shielding plate 254 is removed, and then the servo motor inside the driving unit 2511 is started to drive the active bevel gear 2512 on the purification member 25 to rotate slowly, and the active bevel gear 2512 meshes with the driven bevel gear 2513 to rotate around the inside of the pillar 251, driving the four groups of brackets 252 and the purification cylinder 253 to rotate synchronously, and the purification cylinder 253 rotates 180 degrees, and the saturated activated carbon inside it is automatically separated from the purification cylinder 253 by its own gravity and falls into the collection device inside the purification tank 21. As can be seen from the above, the purification cylinder 253 in the present invention adopts a rotatable structure, and the unloading of activated carbon can be completed at one time without being disassembled, and the automated operation is simple and convenient.

[0046] During installation, the driving unit 2511 utilizes the active bevel gear 2512 to drive the four groups of brackets 252 and the purification cylinder 253 to rotate and reset synchronously. What needs to be emphasized in the present invention is that the purification cylinder 253 in the present invention adopts a "four-layer structure design", which can double the adsorption area of ​​the purification cylinder 253 and avoid the situation where the activated carbon inside the traditional adsorber is insufficiently adsorbed. The purification cylinder 253 includes a first cylindrical plate 2531, a second cylindrical plate 2532, a third cylindrical plate 2533 and a fourth cylindrical plate 2534. The purification cylinder 253 includes a first cylindrical plate 2531, a second cylindrical plate 2532, a third cylindrical plate 2533 and a fourth cylindrical plate 2534, and filter holes are opened inside. The fourth cylindrical plate 2534, the third cylindrical plate 2533, the second cylindrical plate 2532 and the first cylindrical plate 2531 are arranged in sequence from the inside to the outside, and the fourth cylindrical plate 2534 is arranged in sequence from the inside to the outside. The top of the space surrounded by plate 2534 adopts a sealed design, the top of the space surrounded by the second cylindrical plate 2532 and the third cylindrical plate 2533 is fixedly connected with an exhaust plate 2535, the bottom of the space surrounded by the first cylindrical plate 2531 and the second cylindrical plate 2532 adopts a sealed design, the bottom of the space surrounded by the third cylindrical plate 2533 and the fourth cylindrical plate 2534 adopts a sealed design, and the bottom of the space surrounded by the first cylindrical plate 2531 and the fourth cylindrical plate 2534 adopts a sealed design. When the ethylene tar oil pool waste gas is introduced into the purification tank 21, the internal pressure of the purification tank 21 increases, and the waste gas can not only pass through the filter holes on the first cylindrical plate 2531 and flow into the space surrounded by the first cylindrical plate 2531 and the second cylindrical plate 2532, but also pass through the filter holes on the second cylindrical plate 2532 and flow into the space surrounded by the second cylindrical plate 2532 and the third cylindrical plate 2533 (this space is connected to the exhaust end on the exhaust plate 2535). All of the above waste gases need to pass through the first cylindrical plate 2531 and the second cylindrical plate 2532. The exhaust gas can also flow into the space surrounded by the third cylindrical plate 2533 and the fourth cylindrical plate 2534 through the filter holes on the fourth cylindrical plate 2534, and flow into the space surrounded by the second cylindrical plate 2532 and the third cylindrical plate 2533 through the filter holes on the third cylindrical plate 2533 (this space is connected to the exhaust end on the exhaust plate 2535). All of the above exhaust gases need to pass through the space surrounded by the third cylindrical plate 2533 and the fourth cylindrical plate 2534. As can be seen from the above, the purification cylinder 253 in the present invention can be adsorbed from the outer surface and the inner surface simultaneously, and the exhaust gas can fully pass through the activated carbon, thereby improving the utilization rate and purification speed of the activated carbon.After the purification cylinder 253 is rotated and reset, the shielding plate 254 is placed on the upper end of the purification cylinder 253. The shielding plate 254 is provided with an exhaust hole 2541 and a shielding groove 2542 that fit with the exhaust end of the exhaust plate 2535, respectively, for loading and exhausting the activated carbon. When the shielding groove 2542 is engaged above the exhaust end of the exhaust plate 2535, the bottom of the external circular plate 2543 is engaged with the top of the first cylindrical plate 2531 through the circular groove, and the inner side of the internal circular plate 2544 fits with the outer surface of the circumference of the fourth cylindrical plate 2534. The tops of the external circular plate 2543 and the internal circular plate 2544 are much higher than the top of the shielding plate 254. At this time, the activated carbon can be added into the space surrounded by the external circular plate 2543 and the internal circular plate 2544. The activated carbon flows into the space surrounded by the first cylindrical plate 2531 and the second cylindrical plate 2532, and into the space surrounded by the third cylindrical plate 2533 and the fourth cylindrical plate 2534. At the same time, the activated carbon is prevented from flowing into the space surrounded by the second cylindrical plate 2532 and the third cylindrical plate 2533, which facilitates the rapid installation of the activated carbon. Finally, the exhaust hole 2541 is adjusted to fit above the exhaust end of the exhaust plate 2535, and the reset gas storage tank 265 is attached to the upper end of the shielding plate 254.
