Description

Technical Field

[0001] This application relates to the technical field of activated carbon desulfurization and denitrification, and particularly relates to a feeding system and control method for flue gas treatment materials. Background Art

[0002] As a flue gas treatment technology, the activated carbon desulfurization and denitrification process can efficiently remove harmful substances such as dust, SO2, NO X , dioxins, and heavy metals in power, sintering, pelletizing and other processes.

[0003] The carbon circulation amount of the activated carbon system needs to be adjusted according to the SO2 concentration at the system inlet and the desorption effect of the desorption tower. The adjustment of the carbon circulation amount is mainly controlled by the aperture size of the throttle orifice plate under the discharge hopper of the adsorption tower. Replacing the throttle orifice plate is usually arranged during the shutdown of the sintering machine or the rotary kiln of the grate-kiln. Because the flue gas inlet and outlet valves of the adsorption tower are butterfly valves, there is a problem of flue gas leakage. For online replacement, it is necessary to block the flue gas channels at the inlet and outlet with blind flanges. First, the workload is large and there are safety hazards. Second, after the adsorption tower is withdrawn, the flue gas treatment capacity of the system decreases, affecting the efficiency of the main unit. The diameter of the throttle orifice plate is obtained through experiments according to the number of activated carbon desulfurization and denitrification modules, the feeding sequence of each module, and the feeding interval between each module, so as to meet the required carbon circulation amount of the system.

[0004] The throttle orifice plate is difficult to install and cannot be adjusted during use. There are problems such as the inability to increase the carbon circulation amount of the system, large deviation in the feeding amount before and after the service life, resulting in the overflow of activated carbon in the chain bucket conveyor in the later stage, affecting the output of sintering or pelletizing.

Detailed implementation manners

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms and should not be construed as limited to the embodiments described herein.

[0033] As Figure 1 shown, Figure 1 Schematic structural diagram of the feeding system provided by the embodiment of the present application. A feeding system for flue gas treatment materials, the feeding system includes an accommodating member 100, a conveying device 200, a control valve 300, and an adjusting member 400, wherein:

[0034] An emptying cavity for accommodating materials is provided inside the accommodating member 100. The accommodating member 100 has a feeding port 101 and a discharging port 102. An emptying cavity is designed inside the accommodating member 100, which is specifically used to accommodate the materials required for flue gas treatment. A feeding port 101 is provided at the top of the accommodating member 100 for adding materials to the emptying cavity, and a discharging port 102 is provided at the bottom of the accommodating member 100 for discharging the materials.

[0035] The conveying device 200 is arranged under the accommodating member 100, and the conveying device 200 extends to the lower part of the discharging port 102 to transport the materials discharged from the discharging port 102 to a target position. The conveying device 200 is located under the accommodating member 100, forming a spatial connection with the discharging port 102. The conveying device 200 can extend to the lower part of the discharging port 102, so that the materials discharged from the discharging port 102 can be effectively transported. The main function of the conveying device 200 is to transport the materials from the discharging port 102 to a designated target position for subsequent processing or storage.

[0036] As Figure 1As shown, the control valve 300 is provided at the discharge port 102 to control the flow rate of the material at the discharge port 102. The control valve 300 is installed at the discharge port 102, and its main function is to control the flow rate of the material discharged from the discharge port 102 and provide a certain control authority threshold to ensure reliable and permitted operation. The control valve 300 can adjust the opening degree as needed to adapt to different material processing requirements and ensure the stable flow and precise control of the material.

[0037] The adjusting member 400 is provided on the accommodating member 100 and extends into the filling cavity. The adjusting member 400 can be blocked on the path of the material moving to the discharge port 102 to control the flow rate of the material moving to the discharge port 102.

[0038] As Figure 1 shown, the adjusting member 400 is installed on the upper part of the accommodating member 100 and extends into the filling cavity. The adjusting member 400 can be blocked on the path of the material moving to the discharge port 102, thereby controlling the flow of the material to the discharge port 102.

[0039] The adjusting member 400 can be adjusted as needed to change the flow rate and flow of the material, achieving precise adjustment of the material flow. The entire blanking system realizes efficient management and control of the flue gas treatment material through the collaborative work of the components. It not only improves the efficiency of material processing but also ensures the stability and reliability of the processing process, which is of great significance for improving the flue gas treatment effect.

[0040] In an alternative embodiment, the blanking system in the present application serves the flue gas treatment material, and the working principle of the blanking system is as follows: The blanking system includes a housing 100, a conveying device 200, a control valve 300, and an adjusting member 400. A loading cavity for accommodating the material is provided inside the housing 100. The housing 100 has a feeding port 101 and a discharging port 102. The conveying device 200 is arranged below the housing 100 and extends to the lower part of the discharging port 102 to transfer the material discharged from the discharging port 102 to the target position. The control valve 300 is arranged at the discharging port 102 to control the flow rate of the material at the discharging port 102. The adjusting member 400 is arranged on the housing 100 and extends into the loading cavity. The adjusting member 400 can be blocked on the path where the material moves to the discharging port 102 to control the flow rate of the material moving to the discharging port 102. During the blanking operation of the flue gas treatment material, the pre-loaded material is gathered in the loading cavity of the housing 100. After the control valve 300 is authorized to be opened, the material can pass through the discharging port 102 and be discharged onto the conveying device 200, and then be transferred to the target position through the conveying device 200. At different times during the production stage, the flow rate of the material at the discharge port is controlled in real time by operating the adjusting member 400 to flexibly meet the operation purpose of online adjusting the blanking amount of the adsorption tower and the carbon circulation amount, maintain the stability of the blanking amount, solve the problem of the change of the blanking amount in the early and late stages of the production stage, and at the same time avoid the shutdown operation caused by online replacement due to serious wear during the service life, ensure the production efficiency of the sintering machine, and can adjust the blanking amount of the adsorption tower and the overall carbon circulation amount without replacement operation, which is beneficial to improving the desulfurization efficiency of activated carbon, reducing the consumption of activated carbon, and reducing the labor intensity of the overall operation.

[0041] As Figure 1 、 Figure 2 shown, wherein, Figure 2 FIG. is a schematic structural diagram of the adjusting member 400 provided in the embodiment of the present application. In an alternative embodiment, the adjusting member 400 includes two oppositely arranged blocking portions 401, and the blocking portions 401 are respectively arranged on the outer side of the housing 100 and can extend into the housing 100.

[0042] The adjusting member 400 includes two oppositely arranged blocking portions 401. These two blocking portions 401 are located on the outer side of the housing 100 and can extend into the housing 100 as needed. Allowing the adjusting member 400 to flexibly intervene in the material flow path type without affecting the material storage, and realizing the precise control of the material flow rate.

[0043] As Figure 1 、 Figure 2As shown, in an alternative embodiment, each of the two blocking portions 401 is provided with an attachable edge, so that when the two blocking portions 401 extend into the accommodating member 100, the two blocking portions 401 can contact and block the material through the edges.

[0044] Each blocking portion 401 has an attachable edge. When the two opposite edges of the two blocking portions 401 extend into the interior of the accommodating member 100, they can completely block the material by contacting each other, or the flow rate of the material can be controlled by adjusting the distance between the edges of the two blocking portions 401. This enables the blocking portion 401 to precisely control the flow of the material, prevent excessive flow or premature discharge of the material, and ensure that the material moves at a predetermined flow rate and speed.

[0045] In an alternative embodiment, the accommodating member 100 is provided with a through groove, and the blocking portion 401 is movably disposed in the through groove. The blocking portion 401 has an edge retained outside the accommodating member 100 and an edge retained inside the accommodating member 100.

[0046] The accommodating member 100 is provided with a through groove, which serves as a channel for the movable blocking portion 401. The blocking portion 401 can move freely in the through groove, allowing it to be adjusted according to the needs of material flow to achieve the best material control effect. This mobility of the blocking portion 401 provides higher operational flexibility, enabling the system to adapt to different material handling requirements.

[0047] The blocking portion 401 has an edge retained outside the accommodating member 100 and an edge retained inside the accommodating member 100. The outer edge helps to fix and position the blocking portion 401 outside the accommodating member 100, while the inner edge restricts the flow of the material through its relative position. This ensures that while controlling the material flow, the blocking portion 401 can also be stably fixed on the accommodating member 100.

[0048] In an alternative embodiment, a seal is provided between the accommodating member 100 and the blocking portion 401. The seal prevents the material from leaking or escaping during the flow process. The presence of the seal ensures the continuity and stability of the material flow, and also helps to maintain the cleanliness of the system and reduce environmental pollution.

[0049] The seal can also reduce the noise and vibration caused by the material flow, improving the operating efficiency and safety of the system.

[0050] Such as Figure 1 、 Figure 2As shown, in an alternative embodiment, the adjusting member 400 further includes two driving portions 402 respectively connected to the blocking portion 401, and the driving portions 402 are configured to drive the blocking portion 401 to move closer to or away from each other.

[0051] The adjusting member 400 includes two driving portions 402, and the two driving portions 402 are respectively connected to the two blocking portions 401. The driving portions 402 drive the blocking portions 401 to move closer to or away from each other, thereby adjusting the path and flow rate of the material flow. This enables the adjusting member 400 to dynamically adjust the position of the blocking portion 401 according to the requirements of material processing, achieving precise control of the material flow.

[0052] As Figure 1 、 Figure 2 As shown, in an alternative embodiment, the driving portion 402 includes a positioning frame 403 fixedly connected to the accommodating member 100, and a screw rod 404 threadedly connected to the positioning frame 403. The screw rod 404 is rotatably connected to the blocking portion 401 such that when the screw rod 404 rotates on the positioning frame 403, the screw rod 404 pushes and pulls the blocking portion 401 to move reciprocally.

[0053] The driving portion 402 includes a positioning frame 403 fixedly connected to the accommodating member 100, and a screw rod 404 threadedly connected to the positioning frame 403. The screw rod 404 is rotatably connected to the blocking portion 401 so that when the screw rod 404 rotates on the positioning frame 403, it can push and pull the blocking portion 401 to move reciprocally. This screw thread and rotation provide a simple and effective mechanism for precisely controlling the position of the blocking portion 401, and thus controlling the material flow.

[0054] As Figure 1 、 Figure 2 As shown, in an alternative embodiment, a rotating handle 405 is fixedly provided on the screw rod 404, and the feeding system further includes a plurality of supporting portions for supporting the screw rod 404.

[0055] A rotating handle 405 is fixedly provided on the screw rod 404, and this rotating handle 405 is used to manually or automatically rotate the screw rod 404. The rotating handle 405 enables the operator to conveniently adjust the position of the screw rod 404, thereby controlling the movement of the blocking portion 401. In an automated system, the rotating handle 405 can also be connected to a motor or other driving devices to achieve automatic control of the position of the blocking portion 401.

[0056] The feeding system further includes a plurality of supporting portions for supporting the screw rod 404. The supporting portions ensure the stability of the screw rod 404 when it rotates and pushes and pulls the blocking portion 401, reduce vibration and wear, improve the reliability and lifespan of the system. The supporting portions also help to disperse the force borne by the screw rod 404, protecting the screw rod 404 and the blocking portion 401 from damage.

[0057] As Figure 1 , Figure 2 shown, in an alternative embodiment, the blanking system further includes a main frame 500, on which the accommodating member 100, the adjusting member 400, the control valve 300, and the conveying device 200 are arranged in order from high to low. The main frame 500 makes the entire system structure compact, facilitating installation and maintenance. The arrangement from high to low on the main frame 500 helps the natural flow of materials, reducing the energy intervention during the conveying process. It improves the efficiency and accuracy of material handling, and also enhances the stability and reliability of the system.
