Technical Field

[0001] The utility model relates to the technical field of hydrogen sulfide purification, in particular to a device for purifying hydrogen sulfide. Background Art

[0002] In the production process of petroleum, natural gas and coal chemical industry, a large amount of tail gas containing hydrogen sulfide is inevitably produced. The content of hydrogen sulfide in the acid gas produced by refineries and coal chemical industry is about 25%-40% (VOL%), and the other main components are nitrogen, carbon dioxide, water, etc. Therefore, in order to better recover hydrogen sulfide and improve the recovery rate of hydrogen element, these tail gases are generally purified to extract the hydrogen sulfide. Common purification methods include pressure swing adsorption and membrane separation. Among them, the pressure swing adsorption method uses the different adsorption capacity, adsorption speed and adsorption amount of adsorbents for different gases to absorb hydrogen sulfide gas under pressurized conditions, and finally releases the hydrogen sulfide in the adsorbent by reducing the pressure, so that pure hydrogen sulfide gas can be extracted.

[0003] However, when using pressure swing adsorption for purification, the pores in the adsorbent are easily blocked by dust particles in the exhaust gas, causing the adsorption effect to weaken. Therefore, the adsorbent needs to be replaced many times. During the replacement, the equipment needs to be shut down and it is necessary to wait for the entire replacement process to be completed before continuing the purification of hydrogen sulfide, which reduces the purification efficiency.

[0004] Therefore, it is necessary to provide a new device for purifying hydrogen sulfide to solve the above technical problems. Utility Model Content

The ends are fixedly connected, and a truncated cone 11 is fixedly installed on the end of the transmission shaft 10 away from the side plate 8, and two slots 12 are provided on the outer ring wall of the truncated cone 11. Plugs 13 are inserted in the two slots 12, and round sleeves 14 are fixedly installed on the sides of the two plugs 13 away from each other, and activated carbon honeycomb adsorption plates 15 are fixedly installed in the two round sleeves 14, one of the activated carbon honeycomb adsorption plates 15 is located between the purification barrel 1 2 and the purification barrel 2 3, and in the use state, the two sealing rings 4 are tightly fitted to the two sides of the activated carbon honeycomb adsorption plate 15 to form a sealing effect.

[0024] In the above method, in order to be able to separate the sealing ring 4 and the circular sleeve 14, a concave seat 5 is fixedly installed on the top of the base 1, and a bidirectional screw 6 is rotatably installed inside the concave seat 5. Two movable plates 7 are threadedly installed on the bidirectional screw 6. The tops of the two movable plates 7 are respectively fixedly connected to the purification barrel 1 2 and the purification barrel 2 3. A motor 1 is fixedly installed on the outer wall of one side of the concave seat 5, and its output shaft is fixedly connected to one end of the bidirectional screw 6. In addition, two reinforcing rods are fixed in the concave seat 5, and the two reinforcing rods pass through the two movable plates 7 and are slidably connected to the two movable plates 7.

[0025] In the present embodiment, in order to facilitate the removal and replacement of the round sleeve 14, a buckle groove 16 is opened on one side of the two plugs 13, and two folding strips 17 are fixedly installed on the side of the round table 11 away from the mounting plate 9. A clamping rod 18 is slidably installed on the two folding strips 17. The ends of the two clamping rods 18 close to the mounting plate 9 extend into the two buckle grooves 16 respectively, thereby forming a clamping state, so that the plug 13 is clamped in the slot 12, and the clamping rod 18 is slidably connected to the round table 11, and a spacer ring 19 is fixedly sleeved on the two clamping rods 18.

[0026] The working principle of the device for purifying hydrogen sulfide provided by the utility model is as follows:

[0027] This device is used in conjunction with external booster equipment;

[0028] When purifying hydrogen sulfide, the tail gas is first introduced into the purification barrel 2, and then after pressure purification, the hydrogen sulfide is sucked into the activated carbon honeycomb adsorption plate 15, and the remaining gas is discharged through the purification barrel 3. After a period of time, the hydrogen sulfide gas is released by reducing the pressure for collection;

[0029] In later use, when the activated carbon honeycomb adsorption plate 15 in use needs to be replaced, the motor 1 can be started in the forward direction first, and its output shaft drives the corresponding bidirectional screw 6 to rotate, so that the two movable plates 7 move away from each other, thereby loosening the middle circular sleeve 14, and then the motor 2 is started, and its output shaft drives the transmission shaft 10 to rotate, and then the round table 11 and the two circular sleeves 14 can be rotated. After the two circular sleeves 14 rotate 180°, they alternate positions with each other, and then the motor 1 is started in the reverse direction to make the two movable plates 7 approach each other, and finally the corresponding circular sleeves 14 are clamped, and the purification work of hydrogen sulfide can continue;

[0030] On the other hand, pull the corresponding clamping rod 18 away from the truncated table 11 and pull it out from the buckle groove 16, so that the used activated carbon honeycomb adsorption plate 15 together with the round sleeve 14 can be removed, and then replace it with a new round sleeve 14 with the activated carbon honeycomb adsorption plate 15, thereby completing the replacement of the activated carbon honeycomb adsorption plate 15;

[0031] Afterwards, this process is repeated repeatedly, thereby realizing the rapid replacement of the activated carbon honeycomb adsorption plate 15 .

[0032] Compared with the related art, the device for purifying hydrogen sulfide provided by the utility model has the following beneficial effects:

[0033] The utility model provides a device for purifying hydrogen sulfide. By setting a rotatable round table 11 and arranging two symmetrical round sleeves 14 on the round table 11, when replacing the activated carbon honeycomb adsorption plate 15, it is only necessary to rotate the round table 11 and exchange the positions of the two round sleeves 14, so that the purification work of hydrogen sulfide can be continued on one side, and at the same time, the used activated carbon honeycomb adsorption plate 15 can be replaced on the other side, which greatly shortens the downtime of the equipment and improves the purification efficiency.
