Description

Technical Field

[0001] This invention belongs to the field of activated coke desorption gas treatment technology, specifically a high-efficiency treatment system for activated coke desorption gas. Background Technology

[0002] Activated coke desorption gas is a gas mixture produced during the activated coke adsorption process. Activated coke is a type of activated carbon with high adsorption capacity. It can remove harmful substances in waste gas, such as sulfur compounds, nitrogen compounds, and organic pollutants, through physical and chemical adsorption. During the activated coke adsorption process, harmful substances in the waste gas are adsorbed into the pores of the activated coke. At the same time, the activated coke also releases some gases, which are called activated coke desorption gas. The main components of activated coke desorption gas include carbon dioxide, nitrogen, water vapor, oxygen, hydrogen sulfide, and ammonia. Among them, carbon dioxide and nitrogen are harmless gases produced during the activated coke adsorption process, while hydrogen sulfide and ammonia are harmful substances in the waste gas. The activated coke desulfurization and denitrification process mainly involves activated coke adsorbing SO2 in flue gas in the adsorption tower. Subsequently, the saturated activated coke is transported to the regeneration desorption tower through a conveying system. In the desorption system, the activated coke will desorb high-concentration SO2 gas, realizing the regeneration treatment of activated coke. Generally, the high-concentration SO2 gas released by the activated coke during the regeneration process will enter the ammonium sulfate preparation system to make ammonium sulfate mother liquor, which will be sent to the purification system for treatment.

[0003] As production requirements become increasingly stringent, the frequency of activated coke desorption needs to be increased, leading to a greater amount of ammonium sulfate mother liquor. This necessitates that the purification system operate at full capacity for extended periods. However, prolonged full-load operation can cause corrosion of the purification system's saturator and result in the release of harmful gases from the overflow tank, posing a safety hazard. Conversely, reducing the amount of ammonium sulfate processed leads to a high density of the ammonium sulfate mother liquor, causing ammonium sulfate crystallization. This, in turn, results in frequent blockages in the desorption system's pipelines and severe corrosion of the mechanical seals of the ammonium sulfate circulation pump and delivery pump. Furthermore, insufficient activated coke desorption can lead to a series of risks, including decreased desulfurization and denitrification efficiency, reduced wear resistance, decreased chemical stability, and blockage of the adsorption tower. When treating SO2 gas, impurities in the SO2 gas can damage the treatment equipment, reducing its service life and failing to meet current requirements. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a high-efficiency treatment system for activated coke desorption gas.

[0005] A high-efficiency treatment system for activated coke desorption gas includes an activated coke regeneration tower and a treatment mechanism connected to the activated coke regeneration tower. The treatment mechanism includes a first conveying pipe connected to the activated coke regeneration tower, a riser control valve installed on the first conveying pipe, a pressure transmitter for monitoring the internal pressure of the first conveying pipe, and a riser variable frequency fan connected to the first conveying pipe. The treatment mechanism also includes a coke oven riser pipe connected to the first conveying pipe, a coke oven carbonization chamber connected to the coke oven riser pipe, and a Claus system located on one side of the coke oven carbonization chamber and connected to the coke oven riser pipe. The coke oven carbonization chamber produces raw coal gas during production, which enters the coke oven riser pipe. Inside the riser pipe, it reacts with high-concentration SO2 to produce H2S. The Claus furnace is a high-efficiency device for treating sulfur-containing waste gas. It mainly consists of two parts: a high-temperature combustion furnace and a catalytic converter. The sulfur-containing waste gas first enters the high-temperature combustion furnace, where it reacts with oxygen in the air at high temperatures to produce sulfur dioxide. This process is like "heating" the waste gas, allowing the sulfur to burn completely, and the generated sulfur dioxide then... Entering the catalytic converter, under the action of the catalyst, it reacts with oxygen to produce sulfur trioxide. This process is like "catalyzing" sulfur dioxide, making it easier for it to react with other substances. After a series of treatments, sulfur trioxide can be transformed into sulfur products. The Claus furnace uses a series of complex processes to recover sulfur from these sulfur-containing waste gases and turn them into useful sulfur products. The generated sulfur products can be sent for external processing and can be used to produce sulfuric acid, sulfur rubber, sulfur fertilizer, etc. The processing mechanism also includes a pipeline purging device installed in the first conveying pipeline to unclog it, an SO2 gas detector alarm to detect SO2 leakage in the first conveying pipeline, and an H2S gas detector alarm to detect H2S leakage at the top of the coke oven riser pipe.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1

[0029] Please see Figure 1This application provides a high-efficiency treatment system for activated coke desorption gas, including an activated coke regeneration tower 1 and a treatment mechanism connected to the activated coke regeneration tower 1; wherein, the treatment mechanism includes a first conveying pipe 2 connected to the activated coke regeneration tower 1, a rise control valve 3 installed on the first conveying pipe 2, a pressure transmitter 4 for monitoring the internal pressure of the first conveying pipe 2, and a rise variable frequency fan 5 connected to the first conveying pipe 2; the treatment mechanism also includes a coke oven riser pipe 6 connected to the first conveying pipe 2, a coke oven carbonization chamber 7 connected to the coke oven riser pipe 6, and a device disposed on one side of the coke oven carbonization chamber 7 and connected to the coke oven carbonization chamber 7. The Claus furnace 8, connected to the coke oven riser pipe 6, is where the raw coal gas containing H2 produced during the coke oven carbonization chamber 7 enters the coke oven riser pipe 6. Inside the riser pipe 6, H2 reacts with high-concentration SO2 to produce H2S. The Claus furnace 8 is a high-efficiency device for treating sulfur-containing waste gas. It mainly consists of two parts: a high-temperature combustion furnace and a catalytic converter. The sulfur-containing waste gas first enters the high-temperature combustion furnace, where it reacts with oxygen in the air at high temperatures to produce sulfur dioxide. This process is like "heating" the waste gas, allowing the sulfur to burn completely, producing... Sulfur dioxide then enters the catalytic converter, where it reacts with oxygen under the action of a catalyst to produce sulfur trioxide. This process acts like a "catalyst" for sulfur dioxide, making it easier to react with other substances. After a series of treatments, sulfur trioxide can be transformed into sulfur products. The Claus furnace 8 uses a series of complex processes to recover sulfur from these sulfur-containing waste gases and turn them into useful sulfur products. The generated sulfur products can be sent for external processing and can be used to produce sulfuric acid, sulfur rubber, sulfur fertilizer, etc. The processing unit also includes a first conveying pipeline 2 that can... The pipeline purging device 9, which unclogs the first conveying pipeline 2, the SO2 gas detection alarm 10, which detects SO2 leakage in the first conveying pipeline 2, and the H2S gas detection alarm 11, which detects H2S leakage at the top of the coke oven riser pipe 6, are used to clean the pipeline. The pipeline purging device 9 uses high-pressure gas, such as nitrogen, to blow out or loosen the blockage in the first conveying pipeline 2 by using the impact force and kinetic energy of the airflow. The pipeline purging device 9 is usually composed of a compressor or gas source, a gas storage tank, a pressure regulator, a purging nozzle, a control valve, and pipeline connectors.

[0030] In one embodiment of this utility model, the rising control valve 3 is opened, and the ammonium sulfate control valve 14 and the reuse control valve 16 are closed, allowing the high-concentration SO2 generated by the activated coke regeneration tower 1 to enter the processing mechanism. The rising variable frequency fan 5 is started, allowing the high-concentration SO2 to enter the coke oven rising pipe 6 through the first conveying pipe 2. The raw coal gas containing H2 generated in the coke oven carbonization chamber 7 during the production process enters the coke oven rising pipe 6, where it reacts with the high-concentration SO2 to produce H2S. The flue gas after the reaction enters the Claus furnace 8, where the H2S in the flue gas further reacts with SO2 to generate sulfur. The generated sulfur can be sent out for processing. The pressure transmitter 4 is used to measure the pressure in the conveying pipe. When the pressure is too high, it indicates that the first conveying pipe 2 is blocked. The pipe purging device 9 is started to automatically clean the first conveying pipe 2, and the pipe purging device 9 is closed when the pressure in the first conveying pipe 2 returns to normal.

[0031] The processing mechanism of this utility model also includes a second conveying pipe 12 connected to a first conveying pipe 2 near the activated coke regeneration tower 1, and an ammonium sulfate preparation system 13 connected to the second conveying pipe 12. The ammonium sulfate preparation system 13 mainly includes an absorption unit, a crystallization unit, and a separation unit. Sulfur-containing gas enters the absorption unit and comes into full contact with ammonia water or other alkaline solutions in the absorption tower. The sulfides are absorbed and converted into ammonium sulfate solution. The ammonium sulfate solution then enters the crystallization unit, where ammonium sulfate crystallizes by cooling or evaporation concentration. The crystallized mixture enters the separation unit and is processed by centrifugation or filtration. The machine separates ammonium sulfate crystals from the mother liquor. The second conveying pipe 12 is equipped with an ammonium sulfate control valve 14 and an ammonium sulfate induced draft fan 50 corresponding to the ammonium sulfate preparation system 13. When the ammonium sulfate induced draft fan 50 malfunctions and the production pressure is low, the rising control valve 3 and the reuse control valve 16 are opened, the ammonium sulfate control valve 14 is closed, and high-concentration SO2 is reintroduced into the ammonium sulfate preparation system 13 through the rising system. The second conveying pipe 12 is equipped with a third conveying pipe 15 connected to the first conveying pipe 2 on the side near the coke oven rising pipe 6. The third conveying pipe 15 is equipped with a reuse control valve 16.

[0032] In this utility model, a filter mechanism is provided between the rise control valve 3 and the pressure transmitter 4. The filter mechanism can filter the high concentration of SO2 generated in the activated coke regeneration tower 1. A gas check valve 17 is installed on the first conveying pipeline 2 between the filter mechanism and the pressure transmitter 4. The gas check valve 17 can prevent gas backflow.

[0033] As one embodiment of this utility model, when the ammonium sulfate induced draft fan 50 malfunctions and the production pressure is low, the rising control valve 3 and the reuse control valve 16 are opened, the ammonium sulfate control valve 14 is closed, and high-concentration SO2 is reintroduced into the ammonium sulfate preparation system 13 through the rising system.

[0034] In summary, opening the riser control valve 3 and closing the ammonium sulfate control valve 14 and the reuse control valve 16 allows the high-concentration SO2 generated by the activated coke regeneration tower 1 to enter the processing unit. Starting the riser variable frequency fan 5 allows the high-concentration SO2 to enter the coke oven riser pipe 6 through the first conveying pipe 2. During production, the raw coal gas containing H2 generated in the coke oven carbonization chamber 7 enters the coke oven riser pipe 6, where it reacts with the high-concentration SO2 to produce H2S. The resulting flue gas enters the Claus furnace 8, where the H2S and SO2 further react... The reaction produces sulfur, which can be sent for external processing. The pressure transmitter 4 is used to measure the pressure inside the conveying pipeline. When the pressure is too high, it indicates that the first conveying pipeline 2 is blocked. The pipeline purging device 9 will be started to automatically clean the first conveying pipeline 2. When the pressure inside the first conveying pipeline 2 returns to normal, the pipeline purging device 9 will be shut off. When the ammonium sulfate induced draft fan 50 malfunctions and the production pressure is low, the rise control valve 3 and the reuse control valve 16 are opened, and the ammonium sulfate control valve 14 is closed. The high concentration of SO2 is reintroduced into the ammonium sulfate preparation system 13 through the rise system.

The moving fixed rod 37 drives the circular fixed block 38 to move. The circular fixed block 38 drives the limit spring 39 to press, moving the fixed rod 37 out of the fixed hole. The collection box 35 is moved, causing the fixed slide bar 36 to slide in the fixed slide groove, thus removing the collection box 35 from the collection seat 34 for disassembly and maintenance.

[0047] In summary, the first conveying pipe 2 introduces high-concentration SO2 into the filter box 18, allowing the filter plate 19 to filter the high-concentration SO2. The filtered high-concentration SO2 is then introduced into the first conveying pipe 2. When the box door 21 is opened to disassemble the filter plate 19, moving the filter plate 19 causes the limiting strip 49 to move within the limiting groove, thus separating the filter plate 19 from the two sets of limiting seats 20. The first drive motor 27 is then started, causing the first bevel gear 28 to rotate. The first bevel gear 28 drives the two sets of second bevel gears 29 to rotate. The second bevel gears 29, through the transmission rod 30, drive the third bevel gear 31 to rotate. The third bevel gear 31 drives the fourth bevel gear 32 to rotate. The fourth bevel gear 32 drives the screw transmission device 23 to rotate, causing the screw transmission device 23 to move the cleaning brush 22. As the cleaning brush 22 moves, it causes the guide block 24 to slide on the guide rod 25. During its movement, the cleaning brush 22 cleans the filter plate 19. The filter plate 19 is cleaned to remove impurities adhering to it, and the impurities are discharged into the collection box 35 through the discharge port 33. Once the collection box 35 is full, the second drive motor 41 is activated, driving the sprocket 47 to rotate. The sprocket 47, via the chain 48, controls another set of sprockets 47 to rotate. The sprocket 47 drives the first gear 46 to rotate, and the other set of sprockets 47 drives the second gear 51 to rotate. The second gear 51 then drives the first gear 46 to rotate. 46 rotates to move rack 45, rack 45 moves moving plate 43, moving plate 43 moves sealing plate 42 to block discharge port 33, moving fixed rod 37 moves circular fixed block 38, circular fixed block 38 moves limiting spring 39 to squeeze, moving fixed rod 37 out of fixed hole, moving collection box 35 moves fixed slide bar 36 to slide in fixed slide groove, collection box 35 is removed from collection seat 34, collection box 35 is disassembled and maintained.
