Description

Technical Field

[0001] The invention belongs to the technical field of active coke desorption gas treatment, and in particular is an efficient treatment system applied to active coke desorption gas. Background Art

[0002] Activated coke desorption gas is a gas mixture produced during the activated coke adsorption treatment process. Activated coke is an activated carbon with high adsorption performance. It can remove harmful substances in waste gas by physical adsorption and chemical adsorption, such as sulfur compounds, nitrogen compounds, organic pollutants, etc. In the activated coke adsorption treatment process, harmful substances in the waste gas are adsorbed into the pores of the activated coke. At the same time, the activated coke will also release some gases, which are activated coke desorption gas. The main components of activated coke desorption gas include carbon dioxide, nitrogen, water vapor, oxygen, hydrogen sulfide, ammonia, etc. Among them, carbon dioxide and nitrogen are harmless gases produced during the activated coke adsorption process, while hydrogen sulfide, ammonia, etc. are harmful substances in the waste gas. The activated coke desulfurization and denitrification process mainly uses activated coke to adsorb SO2 in the flue gas in the adsorption tower, and then the adsorption saturated activated coke is transported to the regeneration desorption tower through the conveying system. In the desorption system, the activated coke will decompose high-concentration SO2 gas to realize the regeneration 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 analysis needs to be increased, and the amount of ammonium sulfate mother liquor generated increases, resulting in the need for the purification system to ensure long-term full-load operation. However, if the purification system is operated at full load for a long time, it will lead to corrosion of the purification system saturator, and will be accompanied by the overflow of harmful gases in the full flow tank, posing a safety hazard; if the amount of ammonium sulfate processed is reduced, the density of the ammonium sulfate mother liquor will be high, causing ammonium sulfate crystallization, and then causing frequent blockages in the analysis system pipelines, and serious corrosion of the ammonium sulfate circulation pump and delivery pump seals. At the same time, insufficient activated coke analysis will lead to a series of risks such as decreased desulfurization and denitrification efficiency, reduced wear resistance, reduced chemical stability, and blockage of the adsorption tower. When treating SO2 gas, the impurities contained in the SO2 gas will damage the treatment mechanism, reducing the service life of the treatment mechanism, and failing to meet people's needs.

[0028] Embodiment 1

[0029] See also Figure 1The present application provides an efficient processing system for activated coke decomposition gas, comprising an activated coke regeneration tower 1 and a processing mechanism connected to the activated coke regeneration tower 1; wherein the processing mechanism comprises a first conveying pipeline 2 connected to the activated coke regeneration tower 1, an ascending control valve 3 installed on the first conveying pipeline 2, a pressure transmitter 4 for monitoring the internal pressure of the first conveying pipeline 2, and an ascending variable frequency fan 5 connected to the first conveying pipeline 2; the processing mechanism also comprises a coke oven ascending pipe 6 connected to the first conveying pipeline 2, a coke oven carbonization chamber 7 connected to the coke oven ascending pipe 6, and a coke oven carbonization chamber 7 arranged on one side of the coke oven carbonization chamber 7 and connected to the coke oven carbonization chamber 7. The coke oven riser pipe 6 is connected to the Claus furnace 8. The raw gas containing H2 generated in the coke oven carbonization chamber 7 during the production process will enter the coke oven riser pipe 6, and react with high-concentration SO2 in the coke oven riser pipe 6 to produce H2S. The Claus furnace 8 is a high-efficiency equipment for treating sulfur-containing waste gas. The Claus furnace 8 is mainly composed of two parts: one part is a high-temperature combustion furnace, and the other part is a catalytic converter. The sulfur-containing waste gas first enters the high-temperature combustion furnace and undergoes a combustion reaction with oxygen in the air at high temperature to generate sulfur dioxide. This process is like "heating" the waste gas to fully burn the sulfur element in it and generate The sulfur dioxide then enters the catalytic converter and reacts with oxygen under the action of the catalyst to generate sulfur trioxide. This process is like "catalyzing" the sulfur dioxide, making it easier for it to react with other substances. After a series of treatments, the sulfur trioxide can be turned into a sulfur product. The Claus furnace 8 recovers the sulfur element in these sulfur-containing exhaust gases through a series of complex processes and turns them into useful sulfur products. The generated sulfur products can be sent out for treatment. The sulfur products can be used to produce sulfuric acid, sulfur rubber, sulfur fertilizers, etc. The processing mechanism also includes a first transmission pipeline 2 that can be used for The pipeline purge device 9 for clearing the first conveying pipeline 2, the SO2 gas detection alarm 10 for detecting SO2 leakage in the first conveying pipeline 2 and the H2S gas detection alarm 11 for detecting H2S leakage at the top of the coke oven riser 6. The pipeline purge device 9 uses the high-speed injection of high-pressure gas such as nitrogen to blow out or loosen the blockage in the first conveying pipeline 2 by utilizing the impact force and kinetic energy of the airflow, thereby achieving the purpose of clearing the pipeline. The pipeline purge device 9 is usually composed of a compressor or gas source, a gas storage tank, a pressure regulator, a purge nozzle, a control valve and pipeline connectors.

[0030] As an embodiment of the present invention, the rising control valve 3 is opened, the ammonium sulfate control valve 14 and the reuse control valve 16 are closed, so that the high concentration SO2 generated by the activated coke regeneration tower 1 can enter the processing mechanism, and the rising variable frequency fan 5 is started, so that the high concentration SO2 enters the coke oven riser 6 through the first conveying pipeline 2. The coke oven carbonization chamber 7 produces raw gas containing H2 during the production process, which will enter the coke oven riser 6, and react with the high concentration SO2 in the coke oven riser 6 to produce H2S. The flue gas after the reaction enters the Claus furnace 8, and the H2S in the flue gas further reacts with SO2 to generate sulfur. The generated sulfur can be sent out for treatment. The pressure transmitter 4 is used to measure the pressure in the conveying pipeline. When the pressure is too high, it means that the first conveying pipeline 2 is blocked. The pipeline purge device 9 will automatically start to clean the first conveying pipeline 2, so that the pipeline purge device 9 is closed when the pressure in the first conveying pipeline 2 returns to normal.

[0031] The processing mechanism of the present invention further includes a second delivery pipeline 12 connected to the first delivery pipeline 2 near one side of the activated coke regeneration tower 1 and an ammonium sulfate preparation system 13 connected to the second delivery pipeline 12. The ammonium sulfate preparation system 13 mainly includes an absorption unit, a crystallization unit and a separation unit. The sulfur-containing gas enters the absorption unit and is fully contacted with ammonia water or other alkaline solutions in the absorption tower. The sulfide is absorbed and converted into ammonium sulfate solution. The ammonium sulfate solution then enters the crystallization unit. The ammonium sulfate crystallization is promoted by cooling or evaporation concentration. The crystallized mixture enters the separation unit and is separated by a centrifuge or a filter. Ammonium sulfate crystals are separated from the mother liquor, and an ammonium sulfate control valve 14 and an ammonium sulfate induced draft fan 50 corresponding to the ammonium sulfate preparation system 13 are provided on the second conveying pipeline 12. When the ammonium sulfate induced draft fan 50 fails and the production pressure is relatively low, the rising control valve 3 and the recycling control valve 16 are opened, and the ammonium sulfate control valve 14 is closed to reintroduce high-concentration SO2 into the ammonium sulfate preparation system 13 through the rising system. The second conveying pipeline 12 is provided with a third conveying pipeline 15 connected to the first conveying pipeline 2 close to the coke oven riser 6, and the third conveying pipeline 15 is provided with a recycling control valve 16.

[0032] In the present invention, a filtering mechanism is arranged between the rising control valve 3 and the pressure transmitter 4, and the filtering mechanism can filter the high-concentration SO2 generated in the activated coke regeneration tower 1. A gas one-way valve 17 arranged between the filtering mechanism and the pressure transmitter 4 is installed on the first conveying pipeline 2, and the gas one-way valve 17 can prevent gas reflux.

[0033] As an embodiment of the present invention, when the ammonium sulfate induced draft fan 50 fails and the production pressure is low, the rising control valve 3 and the recycling control valve 16 are opened, the ammonium sulfate control valve 14 is closed, and the high concentration SO2 is reintroduced into the ammonium sulfate preparation system 13 through the rising system.

[0034] In summary, the rising control valve 3 is opened, the ammonium sulfate control valve 14 and the recycling control valve 16 are closed, so that the high-concentration SO2 produced by the activated coke regeneration tower 1 can enter the treatment mechanism, and the rising variable frequency fan 5 is started, so that the high-concentration SO2 enters the coke oven rising pipe 6 through the first conveying pipeline 2. The raw gas containing H2 produced in the coke oven carbonization chamber 7 during the production process will enter the coke oven rising pipe 6, and react with the high-concentration SO2 in the coke oven rising pipe 6 to produce H2S. The flue gas after the reaction enters the Claus furnace 8, and the H2S in the flue gas further reacts with SO2. The step reaction generates sulfur, which can be sent out for treatment. The pressure transmitter 4 is used to measure the pressure in the conveying pipeline. When the pressure is too high, it indicates that the first conveying pipeline 2 is blocked. The pipeline purge device 9 will automatically start to clean the first conveying pipeline 2, so that the pressure in the first conveying pipeline 2 returns to normal. The pipeline purge device 9 is closed. When the ammonium sulfate induced draft fan 50 fails and the production pressure is relatively low, the rising control valve 3 and the reuse control valve 16 are opened, and the ammonium sulfate control valve 14 is closed to reintroduce the high-concentration SO2 into the ammonium sulfate preparation system 13 through the rising system.
