Description

Technical Field

[0001] This utility model relates to the field of tubular reactor technology, and more specifically to a tubular reactor with anti-clogging function. Background Technology

[0002] In the wet scrubbing process of acid production from nickel-copper smelting flue gas, a large amount of acidic wastewater containing harmful elements such as nickel, copper, and arsenic is generated. This acidic wastewater needs to be sulfided before being degassed using a degassing tower. The sulfidation reaction is usually carried out in a tubular reactor. However, the heavy metal sulfides and arsenic sulfides generated by the sulfidation reaction are prone to precipitation. As the precipitation forms, it gradually clogs the tubular reactor, preventing the sulfidation reaction from proceeding.

[0003] Existing patent CN202220530834.3 provides a tubular reactor with an anti-clogging device, including a main inlet pipe and a tubular reactor. A flow sedimentation device is provided between the main inlet pipe and the tubular reactor, and also in the middle of the tubular reactor. The flow sedimentation device includes a flow tube, with an inlet on one side of the flow tube and an outlet on the other side. A guide plate is provided between the inlet and outlet. The bottom of the flow tube has a rectangular cross-section and a sedimentation receiving plate. Multiple sets of sedimentation receiving plates are fixed to a rotating shaft in a scattering arrangement. This invention guides the fluid entering the flow tube, increases the fluid's travel distance within the flow tube, and guides the fluid's flow direction, making it easier for sediment in the fluid to accumulate at the bottom of the flow tube, thus preventing clogging of the tubular reactor. It uses a baffle plate to guide the fluid downwards, and after passing through the baffle plate, it flows upwards and is discharged from the outlet. However, the baffle plate of this design also accumulates sediment, which is difficult to clean. Utility Model Content

[0004] In view of this, the present invention aims to provide a tubular reactor with anti-clogging function to at least partially solve the technical problem in the prior art where the guide plate also adheres to sediments and is difficult to clean.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tubular reactor with anti-clogging function includes a tubular reactor body and a plurality of flow sedimentation components spaced apart along the length of the tubular reactor body. The flow sedimentation components include:

[0007] A sedimentation cylinder, wherein the upper sidewall of the sedimentation cylinder is symmetrically provided with a feed inlet and a discharge outlet, and the bottom is provided with a sedimentation outlet;

[0008] A sliding drive mechanism is fixed to the top of the sedimentation tank;

[0009] Multiple guide plates are evenly spaced along the direction of vertical feeding. The surface of each guide plate is arranged along the feeding direction of the feed inlet. Each guide plate is fixedly connected to the output end of the sliding drive mechanism at one end and extends through the top wall of the sedimentation cylinder to the upper inner cavity of the sedimentation cylinder at the other end.

[0010] The beneficial effects that this utility model can achieve are: when the fluid flows through the gap between multiple guide plates, it is disturbed by the guide plates, causing the sediment to be deposited on the guide plates and fall to the bottom of the sedimentation cylinder under the action of gravity; the guide plates can be driven to slide on the inner wall of the sliding hole by the sliding drive mechanism, scraping off the sediment attached to them, which is convenient for cleaning.

[0011] Preferably, a protective cover is detachably installed on the top of the sedimentation tank, and the sliding drive mechanism is installed inside the protective cover.

[0012] Preferably, the sliding drive mechanism includes an electric telescopic rod and a push plate. The electric telescopic rod is fixed to the top of the sedimentation cylinder, and the push plate is fixed to the telescopic end of the electric telescopic rod. The top of the sedimentation cylinder is provided with multiple sliding holes, and the top of the guide plate passes through the sliding holes and connects to the push plate.

[0013] Preferably, a sealing ring is installed inside the sliding hole.

[0014] Preferably, the diameter of the feed inlet gradually increases along the feed direction.

[0015] Preferably, the diameter of the discharge port gradually decreases along the discharge direction.

[0016] Preferably, the guide plate has multiple guide grooves along its height direction on its surface, and each guide groove is arranged downwardly along the feeding direction of the feed inlet.

[0017] Preferably, the inclination angle of the guide channel is 10°-30°.

[0018] Preferably, a cleaning brush is fixed at the bottom of the sliding hole, and the cleaning end of the cleaning brush is slidably connected to the surface of the guide plate.

[0019] Preferably, a discharge valve is installed at the sedimentation outlet.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a tubular reactor with anti-clogging function. The guide plate can guide and disturb the fluid, so that the precipitates generated in the fluid are deposited on the guide plate and fall to the bottom of the sedimentation tank for discharge. The guide plate can be scraped off by the sliding drive mechanism, which makes it easy to clean the guide plate. Attached Figure Description

[0027] Please see Figures 1-2 This utility model discloses a tubular reactor with anti-clogging function, including a tubular reactor body and a plurality of flow sedimentation components arranged at intervals along the length of the tubular reactor body. The flow sedimentation components include:

[0028] The sedimentation cylinder 1 has a feed inlet 11 and a discharge outlet 12 symmetrically opened on the upper side wall, and a sedimentation outlet 13 opened at the bottom. A discharge valve is installed at the sedimentation outlet 13.

[0029] Sliding drive mechanism 2, which is fixed to the top of sedimentation tank 1;

[0030] Multiple guide plates 3 are evenly spaced along the direction of vertical feeding. The surface of each guide plate 3 is arranged along the feeding direction of the feed inlet 11. Each guide plate 3 is fixedly connected to the output end of the sliding drive mechanism 2 at one end, and the other end extends through the top wall of the sedimentation cylinder 1 to the upper inner cavity of the sedimentation cylinder 1.

[0031] A protective cover 4 is detachably installed on the top of the sedimentation tank 1, and the sliding drive mechanism 2 is installed inside the protective cover 4. This serves to protect the internal drive mechanism.

[0032] The sliding drive mechanism 2 includes an electric telescopic rod 21 and a push plate 22. The electric telescopic rod 21 is fixed to the top of the sedimentation cylinder 1, and the push plate 22 is fixed to the telescopic end of the electric telescopic rod 21. The top of the sedimentation cylinder 1 is provided with multiple sliding holes, the number of which corresponds to the number of guide plates 3. The top of the guide plate 3 passes through the sliding holes and connects to the push plate 22.

[0033] A sealing ring 5 is installed inside the sliding hole to prevent leakage during the reaction process.

[0034] The diameter of the feed inlet 11 gradually increases along the feed direction. This slows down the fluid as it enters the settling cylinder 1, enhancing the settling effect.

[0035] The diameter of the discharge port 12 gradually decreases along the discharge direction. This allows the fluid to regain its flow rate when it exits the settling cylinder 1, thus meeting the reaction requirements.

[0036] Multiple guide grooves 31 are formed on the surface of the guide plate 3 along its height direction, and each guide groove 31 is arranged downwardly along the feeding direction of the feed inlet 11.

[0037] The inclination angle of the guide channel 31 is 10°-30°. The material deposited on the guide plate 3 flows downward through the guide channel 31 to the bottom of the sedimentation cylinder 1, so that the sediment can be discharged smoothly.

[0038] A cleaning brush 6 is fixed at the bottom of the sliding hole, and the cleaning end of the cleaning brush 6 is slidably connected to the surface of the guide plate 3. The cleaning brush 6 has a ring structure and can clean the deposits on each surface of the guide plate 3.

[0039] The bottom of the sedimentation tank 1 has a conical structure, which facilitates the discharge of materials.
