Description

Technical Field

[0001] The present invention belongs to the technical field of flue gas purification, and particularly relates to an activated coke collecting and discharging device. Background Art

[0002] The activated coke flue gas purification technology is a relatively mature industrial flue gas pollution control technology. The activated coke flue gas purification system uses Φ9mm columnar activated coke as raw material, which flows from top to bottom in the adsorption tower to adsorb pollutants in the flue gas entering the tower, such as dust, SO 2 etc. Since the flue gas treated by the activated coke contains SO 2 , moisture, etc., during the transportation of the activated coke, especially during the collection process of the activated coke, it is extremely easy to stick and form blocks, resulting in poor material discharge and causing harm. The existing activated coke collecting device directly connects a square material collecting box body to the discharge chute pipe and is placed under the platform, and has the following problems.

[0003] 1) The material collecting box is not provided with an inclined plate and is a regular square box body, and it is easy to have a material blockage phenomenon inside the box body.

[0004] 2) The square material collecting box body is located under the platform. When overhauling (opening the manhole on the side of the box body to clean the accumulated material inside), a scaffold needs to be erected. And because the square box body is close to the upper platform, the maintenance workers cannot work upright on the scaffold, and the overhaul is inconvenient. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an activated coke collecting and discharging device, which can effectively collect the activated coke, avoid or reduce the material blockage phenomenon, and is convenient for on-site maintenance.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0007] An activated coke collecting and discharging device of the present invention is characterized in that it includes a closed material collecting box body, an intermediate feed pipe, two side feed ports and a discharge pipe. The material collecting box body includes an upper rectangular box body and a lower triangular prism box hopper integrated with the upper rectangular box body. The rectangular box body is a rectangular box body with an open bottom, which is composed of a left vertical plate, a right vertical plate, a front vertical plate, a rear vertical plate and an upper cover plate. An intermediate feed port is opened in the upper middle part of the upper cover plate, and the intermediate feed pipe is communicated with the intermediate feed port;

[0008] The described triangular prism box hopper is composed of a left transverse side plate, a left short inclined side plate, a left long inclined side plate, a right transverse side plate, a right short inclined side plate, a right long inclined side plate, and a triangular front vertical plate and a triangular rear vertical plate respectively connected to both ends of the left transverse side plate, the left short inclined side plate, the left long inclined side plate, the right transverse side plate, the right short inclined side plate, and the right long inclined side plate.

[0015] 1. Compared with the currently used collecting box, using this device can quickly discharge the collected activated coke, and the material does not accumulate;

[0016] 2. The baffle plates are arranged on the internal inclined plates to avoid the direct scouring of the inclined plates by the material, forming material hitting material, and prolonging the service life of the device;

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] As Figure 1 , Figure 2 And Figure 3 shown, an activated coke collecting and discharging device of the present invention is characterized in that it includes a closed material collecting box body, an intermediate feed pipe 5, two side feed ports and a discharge pipe 6. The material collecting box body includes a rectangular box body 1 in the upper part and a triangular prism box hopper 2 in the lower part connected to the rectangular box body 1. The rectangular box body 1 is a rectangular box body with an open lower part, which is composed of a left vertical plate 11, a right vertical plate 12, a front vertical plate 17, a rear vertical plate 16 and an upper cover plate 13. An intermediate feed port 14 is opened in the upper middle part of the upper cover plate 13, and the intermediate feed pipe is communicated with the intermediate feed port 14;

[0023] The triangular prism box hopper 2 is composed of a left transverse side plate 21, a left short inclined side plate 23, a left long inclined side plate 25, a right transverse side plate 22, a right short inclined side plate 24, a right long inclined side plate 26, and a triangular front vertical plate 29 and a triangular rear vertical plate 28 respectively connected to both ends of the left transverse side plate 21, the left short inclined side plate 23, the left long inclined side plate 25, the right transverse side plate 22, the right short inclined side plate 24 and the right long inclined side plate 26. One end of the left transverse side plate 21 is connected to the left vertical plate 11 at the lower part of the rectangular box body, and the other end is connected to the left short side inclined plate 23. The other end of the left short side inclined plate 23 is connected to the left long inclined side plate 25. One end of the right transverse side plate 22 is connected to the right vertical plate 12 at the lower part of the rectangular box body, and the other end is connected to the right short side inclined plate 24. The other end of the right short side inclined plate 24 is connected to the right long inclined side plate 26. The upper parts of the triangular front vertical plate 29 and the triangular rear vertical plate 28 are integrally connected to the lower parts of the front vertical plate 17 and the rear vertical plate 16 respectively. Two side feed ports are respectively opened on the left short inclined side plate 23 and the right short inclined side plate 24, and two side feed pipes 4 are respectively communicated with the two side feed ports. The discharge pipe 6 is arranged at the bottom of the triangular prism box hopper 2. Baffle plates 27 are respectively arranged on the left long inclined side plate 25 and the right long inclined side plate 26; The length L of the baffle plate ranges from 20 mm ≤ L ≤ 200 mm;

[0024] The middle part of the rectangular box body 1 is fixed to the lower part of the platform 3 through a bracket 7. The upper cover plate 13 is placed above the platform 3. Two maintenance blind holes are also opened on the upper cover plate 13, and blind flanges 15 are provided on the maintenance blind holes.

[0025] The inclination angle α of the left long inclined side plate 25 and the right long inclined side plate 26 ranges from 30° ≤ α ≤ 80°.

[0026] The width B of the left transverse side plate 21, the left short inclined side plate 23, the left long inclined side plate 25, the right transverse side plate 22, the right short inclined side plate 24 and the right long inclined side plate 26 ranges from 100 mm ≤ B ≤ 1000 mm.

[0027] The blind flange is located above the platform, and the height H from the horizontal plane of the platform 3 ranges from 0 < H ≤ 1200 mm.

[0028] Activated coke enters the material collecting box body through the middle feed inlet and the two side feed inlets respectively. After the activated coke in the middle enters the material collecting box body from the upper part, it does not come into contact with the box body and directly falls vertically. After reaching the bottom of the box body, it is discharged through the discharge pipe 6. The activated coke on both sides converges into the triangular prism box hopper 2 from the two side feed pipes and slides down along the baffle 27 by gravity. The activated coke that enters the triangular prism box hopper 2 earlier forms an activated coke cushion layer due to the blockage of the baffle 27. The activated coke that enters the triangular prism box hopper 2 later slides down along the activated coke cushion layer and is discharged through the discharge pipe 6 after reaching the bottom of the box body. The service life of the material collecting box body is effectively prolonged.

[0029] During shutdown maintenance, open the blind flange 15 located above the box body. The maintenance personnel stand on the platform 3 and use tools to clean the accumulated materials inside, which is convenient for on-site maintenance operations.
