[0002] Since activated carbon and / or activated coke have a high specific surface area and adsorption performance, they are often used as adsorbents in the environmental protection field for water purification, gas filtration, etc.

[0003] In the prior art, an activation furnace is usually used for activation to produce activated carbon and / or activated coke. However, during the production of activated carbon and / or activated coke in the activation furnace, a large amount of high-temperature flue gas is generated in the activation furnace, and the high-temperature flue gas contains a large amount of dust. First, the dust in the high-temperature flue gas needs to be removed by a bag filter, and then the flue gas is recycled or other operations are carried out to avoid pipeline blockage or ensure that the flue gas emissions meet the national emission standards.

[0004] However, the high-temperature gas generated by activation contains a large amount of carbon monoxide and hydrogen, and usually the high-temperature gas is directly discharged after purification, which greatly wastes resources.

[0025] The rotary activation furnace is provided with a furnace head blower, which is used to introduce air or denitrifying gas into the rotary activation furnace to meet the activation needs of the activated raw materials in the rotary activation furnace. The denitrifying gas is a gas containing oxygen and can be air or oxygen that has been denitrified. A gas channel is provided on the side of the furnace head blower away from the rotary activation furnace. The gas channel transports the denitrifying gas to the furnace head blower, which then introduces the denitrifying gas into the rotary activation furnace.

[0026] The rotary activation furnace comprises a converter, a rotating device, a power supply device and a steam connection device. The activated raw materials are activated in the converter to obtain activated coke or activated carbon.

[0027] The converter is a cylindrical structure tilted relative to the horizontal ground surface, with the tilt angle of 10°-20°. The feed port is located at the upwardly tilted end of the converter, through which the activated raw material enters the converter. The discharge port is located at the downwardly tilted end of the converter, through which the activated coke or activated carbon is discharged from the converter.

[0028] The activated raw materials enter the converter through the feed inlet of the converter hearth. After being activated in the converter, activated coke or activated carbon is obtained and discharged from the discharge outlet at the tail of the converter hearth.

The steam spray heads are evenly arranged on the inner wall of the converter, and the steam spray heads are used to evenly spray steam into the interior of the converter.

[0032] A dust removal unit is connected between the activation unit and the diversion pipeline. The dust removal unit removes dust from the activation tail gas generated by the activation unit, removes dust and particulate matter in the activation tail gas, and obtains high-temperature tail gas. Specifically, one end of the diversion pipeline is placed at one end of the converter hearth tail, and the other end is connected to the air inlet of the dust removal unit. The dust removal unit is preferably a bag filter.

[0033] The gas separation unit separates the target gas from the high-temperature tail gas to obtain the target gas. The air outlet of the dust removal unit is connected to the air inlet of the gas separation unit through a diversion pipeline. The separated air outlet of the gas separation unit is connected to the gas collection unit, and the gas collection unit collects the target gas separated by the gas separation unit. The air outlet of the gas collection unit can be connected to the using device of the target gas through a diversion pipeline, or the target gas can be directly sold after collection, and no specific restrictions are made here.

[0034] The gas separation unit is preferably a PSA separation device (pressure swing adsorption separation device). Specifically, the gas separation unit includes a pressurizing device, an adsorption tower group, connecting pipes, and control valves. After the high-temperature tail gas is pressurized by the pressurizing device, it is introduced into the adsorption tower from the bottom of the adsorption tower. The pressure of the pressurized high-temperature gas can specifically be 1.0 - 3.0 MPa. The adsorption tower group is composed of multiple adsorption towers connected in series or in parallel to achieve continuous production, and the adsorption towers are connected through connecting pipes. The adsorption tower includes a tower body, and an adsorbent group is filled in the tower body. The adsorbent group is composed of different adsorbent layers filled from bottom to top.

[0035] The gas separation unit may include a first PSA separation device and a second PSA separation device. The first PSA separation device separates hydrogen in the high-temperature tail gas, and the first gas obtained is hydrogen. The second PSA separation device separates carbon monoxide in the high-temperature tail gas, and the second gas obtained is carbon monoxide.

The second gas collection device is connected to the separated gas outlet of the second PSA separation device through a diversion pipe, and the second gas collection device collects the carbon monoxide separated by the second PSA separation device. The gas outlets of the first PSA separation device and the second PSA separation device are respectively connected.

[0037] After the high-temperature tail gas is separated by the gas separation unit, the target gas and the discharge gas are obtained. The discharge gas is all the remaining gas in the high-temperature tail gas after removing the target gas. The gas separation unit further includes a discharge gas outlet, and the discharge gas outlet introduces the discharge gas into the gas discharge purification unit through a diversion pipe.

[0038] The gas discharge purification unit purifies the discharge gas to make it meet the emission standard, and the gas discharge purification unit discharges the purified gas through a discharge chimney.

[0039] The environment-friendly rotary activation system can separate and collect hydrogen in the high-temperature tail gas, realize the co-production of carbon activation and hydrogen, and avoid energy waste.

[0040] The environment-friendly rotary activation system further includes a waste heat utilization unit, which is connected to the activation unit to recover the waste heat of the high-temperature tail gas and use it for preheating air or denitrifying gas, thereby reducing the energy consumption of the system. The central server is connected to the waste heat utilization unit and exchanges information with the waste heat utilization unit.

[0041] The central server can also optimize the gas distribution ratio in real time and control the inlet ratio of air and denitrifying gas in the activation unit according to the optimized gas distribution ratio. The central server includes a dynamic gas distribution control unit, which uses long short-term memory data to determine the inlet ratio of air and denitrifying gas in the activation unit at the next moment, so as to obtain the optimized gas distribution ratio.

[0042] A hydrogen detection module is arranged at the gas outlet of the gas separation unit. The hydrogen detection module is used to monitor the hydrogen concentration of the gas passing through the gas outlet of the gas separation unit to obtain the hydrogen collection purity value. The hydrogen detection module sends the hydrogen collection purity value to the central server in real time. The hydrogen detection module can also be arranged at any position on the diversion pipeline between the gas outlet of the gas separation unit and the gas collection unit.

[0043] When the hydrogen collection purity value of the hydrogen detection module is less than the set collection threshold, the dynamic gas distribution control unit of the central server determines the inlet ratio of air and denitrifying gas in the activation unit at the next moment, and controls the inlet ratio of air and denitrifying gas in the activation unit through the gas ratio adjustment module of the central server. At the same time, the central server marks the time corresponding to the hydrogen collection purity value as the first adjustment time, and the time interval between two adjacent first adjustment times is the adjustment interval.

[0044] The dynamic gas distribution control unit respectively obtains the hydrogen collection purity value in the first time interval, the inlet ratio of air and denitrifying gas in the activation unit in the second time interval, and the hydrogen collection purity value corresponding to the second time interval. Among them, the duration of the first time interval is less than the duration of the second time interval, and at least two hydrogen collection purity values are included in the first time interval. The first time interval refers to the time period with the current moment as the end point and a moment before the current moment as the starting point; the second time interval refers to the time period within the third duration threshold with any moment before the first time interval as the end point and a moment before that moment as the starting point. The third duration threshold is greater than the time interval of the adjustment interval with the largest duration.

[0045] The hydrogen collection purity value corresponding to the second time interval refers to the hydrogen collection purity value detected at the corresponding time point after extending the separation duration when different feeding ratios of the activation unit air and the nitrogen removal gas are fed at the corresponding time points. The separation duration refers to the time required for the air and / or nitrogen removal gas to be fed into the activation unit and pass through the dust removal unit and the gas separation unit in sequence to reach the gas separation outlet of the gas separation unit. Here, the separation duration can be a preset value and can be modified or input through the input unit of the central server.

[0046] When the hydrogen collection purity value detected by the hydrogen detection module is equal to the preset hydrogen purity threshold, the dynamic gas mixing control unit selects an adjustment strategy for optimizing the gas mixing ratio according to the hydrogen collection purity value in the first time interval.

[0047] When the hydrogen collection purity value detected by the hydrogen detection module is less than the preset hydrogen purity threshold, the dynamic gas mixing control unit determines the feeding ratios of the activation unit air and the nitrogen removal gas at the next moment, that is, the optimized gas mixing ratio at the next moment, among the feeding ratios of the activation unit air and the nitrogen removal gas in the second time interval according to the selected adjustment strategy for optimizing the gas mixing ratio.

[0048] The adjustment strategy at least includes: The first adjustment strategy: select a small air feeding amount among the feeding ratios of the activation unit air and the nitrogen removal gas in the second time interval; The second adjustment strategy: select a medium air feeding amount among the feeding ratios of the activation unit air and the nitrogen removal gas in the second time interval; The third adjustment strategy: select a large air feeding amount among the feeding ratios of the activation unit air and the nitrogen removal gas in the second time interval.

[0049] The dynamic gas mixing control unit selects an adjustment strategy for optimizing the gas mixing ratio according to the hydrogen collection purity value in the first time interval, which specifically includes the following steps: The dynamic gas mixing control unit calculates the purity difference of the hydrogen collection purity value in the first time interval. Specifically, the dynamic gas mixing control unit selects the maximum hydrogen collection purity value and the minimum hydrogen collection purity value among the hydrogen collection purity values in the first time interval; the dynamic gas mixing control unit calculates the purity difference according to the purity difference calculation formula, where the purity difference calculation formula is purity difference = maximum hydrogen collection purity value - minimum hydrogen collection purity value.

[0050] The dynamic gas distribution control unit compares the purity difference with the purity standard value, and selects an adjustment strategy for optimizing the gas distribution ratio according to the comparison result. The purity standard value includes a first purity standard value and a second purity standard value. The first purity standard value and the second purity standard value are preset values, which can be input or modified through the input unit of the central server, and the first purity standard value is less than the second purity standard value. Specifically, when the purity difference is less than the first purity standard value, the dynamic gas distribution control unit selects the first adjustment strategy as the target adjustment strategy; when the purity difference is greater than or equal to the first purity standard value and less than or equal to the second purity standard value, the dynamic gas distribution control unit selects the second adjustment strategy as the target adjustment strategy; when the purity difference is greater than the second purity standard value, the dynamic gas distribution control unit selects the third adjustment strategy as the target adjustment strategy.

[0051] The dynamic gas distribution control unit determines the optimized gas distribution ratio for the next moment according to the selected adjustment strategy for optimizing the gas distribution ratio in the second time interval, which specifically includes the following steps: The dynamic gas distribution control unit selects the gas inlet ratios of air and nitrogen removal gas corresponding to the adjustment strategy from the gas inlet ratios of air and nitrogen removal gas in the activation unit in the second time interval. All the selected gas inlet ratios of air and nitrogen removal gas corresponding to the adjustment strategy form an adjustment ratio set. Specifically, the dynamic gas distribution control unit sorts the gas inlet ratios of air and nitrogen removal gas in the activation unit in the second time interval in descending or ascending order according to the proportion of air inlet volume; selects the gas inlet ratios of air and nitrogen removal gas corresponding to the adjustment strategy to obtain the adjustment ratio set.

[0052] When the adjustment strategy is the first adjustment strategy, from the gas inlet ratios of air and nitrogen removal gas in the activation unit in the second time interval, select the gas inlet ratios of air and nitrogen removal gas with the smallest one-third of the proportion of air inlet volume to obtain the adjustment ratio set corresponding to the first adjustment strategy; When the adjustment strategy is the second adjustment strategy, from the gas inlet ratios of air and nitrogen removal gas in the activation unit in the second time interval, select the gas inlet ratios of air and nitrogen removal gas with the middle one-third of the proportion of air inlet volume to obtain the adjustment ratio set corresponding to the second adjustment strategy; When the adjustment strategy is the third adjustment strategy, from the gas inlet ratios of air and nitrogen removal gas in the activation unit in the second time interval, select the gas inlet ratios of air and nitrogen removal gas with the largest one-third of the proportion of air inlet volume to obtain the adjustment ratio set corresponding to the third adjustment strategy.

[0053] The dynamic gas distribution control unit calculates the optimized gas distribution ratio for the next moment according to the adjustment ratio set. Specifically, the dynamic gas distribution control unit calculates the mean value of the inlet ratios of air and denitrifying gas in the adjustment ratio set, such as the arithmetic mean, weighted mean, etc., which is not specifically limited here.

[0054] After the gas ratio adjustment module of the central server calculates the inlet amount of denitrifying gas according to the optimized gas distribution ratio for the next moment, the central server sends an adjustment command to the gas channel on one side of the rotary activation furnace, and the flow control valve of the gas channel adjusts the amount of denitrifying gas output from the gas channel according to the adjustment command.

[0055] An environment-friendly rotary activation system determines the inlet ratios of air and denitrifying gas for the activation unit at the next moment through long-term and short-term memory data, reduces the inlet amount of denitrifying gas while ensuring the purity of hydrogen collection, and reduces the gas inlet cost during hydrogen collection.

[0056] The dust removal unit includes a bag filter and an infrared imaging device. The bag filter and the infrared imaging device are respectively connected to the central server, and the central server conducts information interaction with the bag filter and the infrared imaging device respectively, including the interaction of control information, the interaction of collection / detection information, etc.

[0057] The working actions and working parameter settings of the bag filter are synchronized to the central server. The infrared imaging device is arranged on the side of the bag filter. It should be noted that this side is preferably the side with the largest filter bag area in the bag filter.

[0058] The infrared imaging device is used to capture the infrared image of the bag filter to obtain a captured image. The infrared imaging device sends the captured image to the central server in real time. The central server uses the point correlation method to judge whether the number of high-temperature dust particles on the surface of the filter bag is abnormal, and repairs the bag filter in time, ensuring the dust removal efficiency of the bag filter.

[0059] The central server includes a dust removal analysis unit. The dust removal analysis unit calculates the number of relevant elements at different critical moments using the point correlation method, and judges the abnormality of the bag filter according to the number of relevant elements at different critical moments.

[0060] The dust removal analysis image includes the dividing line of the area where the filter bag is located in the captured image. The dividing line can form a rectangular area or a continuous U shape corresponding to the arrangement of the filter bags. It should be noted that when the filter bags are fully unfolded, they are also within the dividing line.

[0061] The dust removal analysis unit uses the point correlation method to judge the anomalies of the bag filter, which specifically includes the following steps: The dust removal analysis unit acquires the captured images corresponding to the moment before the last ash cleaning program starts and the moment when the ash cleaning program is completed before the current moment, and obtains the first captured image and the second captured image. The first captured image is an infrared image corresponding to the moment before the ash cleaning program starts, and the second captured image is an infrared image corresponding to the moment when the ash cleaning program is completed.

[0062] The dust removal analysis unit marks the areas where the filter bags are located in the first captured image and the second captured image respectively according to the position of the demarcation line, and obtains the first target image area and the second target image area.

[0063] The dust removal analysis unit respectively performs point correlation transformation on the gray values of each pixel point in the first target image area and the second target image area, and obtains the point correlation matrices corresponding to the first target image area and the second target image area respectively. Specifically, the dust removal analysis unit compares the gray value of the pixel point in the first target image area with the first gray threshold, marks the pixel points with gray values greater than or equal to the first gray threshold as 1, and marks the pixel points with gray values less than the first gray threshold as 0, so as to obtain the first point correlation matrix. The dust removal analysis unit compares the gray value of the second target image area with the second gray threshold, marks the pixel points with gray values greater than or equal to the second gray threshold as 1, and marks the pixel points with gray values less than the second gray threshold as 0, so as to obtain the second point correlation matrix. The first gray threshold is greater than the second gray threshold, and the first gray threshold and the second gray threshold can be input or modified through the input unit. It should be noted that the difference between the first gray threshold and the second gray threshold is equal to the gray value corresponding to the temperature drop of the high-temperature particles before and after the ash cleaning program starts.

[0064] The dust removal analysis unit respectively calculates the number of values of 1 in the point correlation matrices corresponding to the first target image area and the second target image area, and obtains the relevant point values corresponding to the first target image area and the second target image area respectively. Specifically, the dust removal analysis unit calculates the number of values of 1 in the first point correlation matrix to obtain the first relevant point value; the dust removal analysis unit calculates the number of values of 1 in the second point correlation matrix to obtain the second relevant point value.

[0065] The dust removal analysis unit determines whether the bag filter is abnormal according to the difference between the relevant point values corresponding to the first target image area and the second target image area. Specifically, the dust removal analysis unit calculates the difference between the first relevant point value and the second relevant point value to obtain a relevant difference. When the relevant difference is greater than or equal to the standard relevant difference, the bag filter is normal; when the relevant difference is less than the standard relevant difference, the bag filter is abnormal. The standard relevant difference is a preset value, which can be modified or input through the input unit.

[0066] When the bag filter is abnormal, the central server sends an abnormality prompt to the bag filter, and the administrator adjusts the working parameters of the bag filter or chooses to repair the bag filter. Specifically, the abnormality prompt includes the first relevant point value and the second relevant point value. The administrator can judge the cause of the abnormality of the bag filter according to the first relevant point value and the second relevant point value, so as to quickly and accurately select the best maintenance or repair plan, improving the maintenance / repair efficiency.

[0067] When the bag filter is removing dust, although parameters of the filter bag dust removal program can be set, such as the dust removal frequency, dust removal method, dust removal intensity, etc., it is not possible to well determine the recovery situation of the filter bag after the dust removal program. Only when the dust removal parameters are continuously modified and the bag filter still cannot achieve the dust removal efficiency, will it be repaired, thus affecting the working efficiency of the entire system. In the system, the central server uses the point correlation method to monitor the adhesion of high-temperature particles before and after the dust removal program, and timely discovers the abnormality of the bag filter.

However, these embodiments are only examples and cannot be construed that the specific implementation manners of the present invention are limited to the descriptions of these embodiments. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions and transformations can still be made, which should all be regarded as belonging to the protection scope of the present invention.
