Description

Technical Field

[0001] The utility model relates to the field of activated carbon regeneration equipment, in particular to a novel superheated pipeline in an activated carbon regeneration system. Background Art

[0002] Activated carbon is a carbonaceous adsorption material with rich pore structure and huge specific surface area. Its main component is carbon, and it also contains a small amount of oxygen, hydrogen, sulfur, nitrogen and chlorine. Activated carbon is carbonized by high-temperature treatment of organic raw materials (such as fruit shells, coal, wood, etc.), and reacts with gas under air-tight conditions to form a well-developed microporous structure, thereby obtaining high adsorption capacity.

[0003] Activated carbon is widely used in water treatment, air purification, food refining, pharmaceutical decolorization and other fields due to its strong adsorption capacity. For example, in water treatment, activated carbon can effectively remove harmful substances and ions in water; in air purification, it can absorb toxins and odors in the air.

[0004] When the adsorption capacity of activated carbon reaches saturation, it can be regenerated to restore its adsorption capacity so that it can be reused. Steam regeneration is a common method for regenerating granular activated carbon. This method uses water vapor to decompose organic matter adsorbed on activated carbon.

[0005] Steam regeneration method refers to the use of high-temperature steam to treat activated carbon during regeneration to restore its adsorption effect. The high-temperature steam is heated by low-temperature steam through a heater and then transported to the regeneration tank for activated carbon regeneration. The section of the pipeline between the heater and the regeneration tank is called the superheated pipeline. However, the superheated pipeline will expand under the action of high temperature, and the pipeline will become longer, which will cause misalignment or structural damage at the connection between the pipeline and the pipeline, and the connection between the pipeline and the equipment.

[0006] After searching, no relevant patents were found for a new type of overheated pipe structure that can solve the above-mentioned overheated pipe expansion problem. Utility Model Content

[0007] In order to solve the above problems, the utility model proposes a novel superheating pipeline in an activated carbon regeneration system.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] The utility model provides a novel superheated pipe in an activated carbon regeneration system, comprising an outer pipe, an insulation layer, an inner pipe and a flange, wherein the inner pipe is sleeved in the outer pipe, the inner pipe is divided into two sections, an inner pipe one and an inner pipe two, and an expansion gap is left between the inner pipe one and the inner pipe two, the insulation layer is arranged between the outer pipe and the inner pipe, and the flange is arranged at both ends of the superheated pipe.

[0010] With the above technical solution, multiple sections of superheated pipes can be sequentially connected through flanges to form a superheated pipeline, which can be used to transport high-temperature steam for activated carbon regeneration. When high-temperature steam passes through, the expansion amount of the inner pipe can be absorbed through the expansion gap. After the high temperature generated by the high-temperature steam is insulated by the heat-insulating layer, the temperature is already very low when it is conducted to the outer pipe, and the expansion amount generated by the outer pipe will also be greatly reduced.

[0011] Further, one end of the first inner pipe and the second inner pipe close to each other is sleeved inside the sleeve.

[0012] With the above technical solution, the sleeve can position the first inner pipe and the second inner pipe, preventing the inner pipes from shifting during the contraction and expansion process.

[0013] Further, an expansion joint is provided on the outer pipe.

[0014] With the above technical solution, the expansion amount generated by the outer pipe can be absorbed by the expansion joint.

[0015] Further, a water jacket flange is provided on the flange.

[0016] With the above technical solution, by passing cooling water inside the water jacket flange to cool the flange and the water jacket flange, the service life of the flange can be extended.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] The present utility model provides a novel superheated pipe in an activated carbon regeneration system. By dividing the inner pipe into two sections and leaving an expansion gap, the problem of the inner pipe expanding when encountering high-temperature steam is solved. By setting a heat-insulating layer, the influence of the heat of high-temperature steam on the outer pipe is reduced. Further, by setting an expansion joint, the problem of the outer pipe expanding is solved. At the same time, by further setting a water jacket flange at the flange where the pipes are connected to cool the flange and extend the service life of the flange, the problem of misalignment or structural damage at the pipe-to-pipe connection and the pipe-to-equipment connection caused by the expansion of the superheated pipe under high temperature can be avoided.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] See Figure 1-2 , the present invention provides a novel superheated pipeline in an activated carbon regeneration system, including an outer pipe 4, an insulation layer 5, an inner pipe, a sleeve 7, a flange 1 and a water jacket flange 2. The inner pipe is divided into two sections, inner pipe I 6 and inner pipe II 9. One end of the inner pipe I 6 and the inner pipe II 9 that are close to each other is sleeved in the sleeve 7 for positioning by the sleeve 7, and there is an expansion gap 8 between the inner pipe I 6 and the inner pipe II 9. The insulation layer 5 is arranged between the outer pipe 4 and the inner pipe. An expansion joint 3 is provided on the outer pipe 4. The flange 1 is arranged at both ends of the superheated pipeline, and a water jacket flange 2 is provided on the flange 1. Multiple sections of superheated pipelines are sequentially connected through the flange 1 to form a superheated pipeline for transporting high-temperature steam for activated carbon regeneration.

[0026] The present invention provides a water jacket flange 2 at the flange connection of the superheated pipeline, and cooling water is passed through the inside to cool the flange 1 and the water jacket flange 2, extending the service life of the flange. The inner pipe is divided into two parts, inner pipe I 6 and inner pipe II 9, which are positioned by the sleeve 7, and there is an expansion gap 8 left in the middle. When high-temperature steam passes through, the expansion amount of the inner pipe is absorbed by the expansion gap 8. After the high temperature generated by the high-temperature steam is insulated by the insulation layer 5, the temperature is already very low when it is conducted to the outer pipe 4, and the expansion amount generated by the outer pipe 4 is also greatly reduced. Both ends of the superheated pipeline A and B are fixed by brackets, so that the expansion amount generated by the outer pipe 4 is completely absorbed by the expansion joint 3. Each section of the superheated pipeline of the superheated pipeline is composed of this structure, which greatly protects other devices connected thereto and can avoid problems such as misalignment or structural damage at the connection between the pipeline and the pipeline and at the connection between the pipeline and the device caused by the expansion of the superheated pipeline under high temperature.
