Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, specifically to a high-efficiency liquid seal device for desulfurization of blended super activated carbon. Background Technology

[0002] The blended super activated carbon desulfurization tower is the core equipment of the integrated "adsorption-catalytic conversion-resource recovery" process. Its working process can be divided into three steps: 1. High-efficiency adsorption: After pretreatment (such as dust removal and conditioning), the flue gas containing sulfur dioxide (SO2) enters the desulfurization tower through the main pipeline. The SO2 in the flue gas is adsorbed on the surface of the blended super activated carbon (activated carbon with high sulfur capacity and high stability through special process modification); 2. Catalytic conversion: The SO2 adsorbed on the surface of the activated carbon reacts with the oxygen (O2) in the flue gas under the action of a catalyst (such as metal oxide) to produce sulfur trioxide (SO3); 3. Resource-based acid production: When SO3 reaches a certain saturation concentration, it reacts with water (H2O) injected into the desulfurization tower to produce dilute sulfuric acid (H2SO4), which is recovered to the storage tank for reuse through pipeline, realizing a closed-loop cycle of sulfur resources.

[0003] In the design and operation of blended super activated carbon desulfurization towers, the core function of the high-efficiency liquid sealing device is to form a sealing barrier through liquid to prevent gas leakage, maintain stable system pressure, avoid loss of activated carbon particles, and ensure process safety and environmental protection.

[0004] The liquid state in a liquid-sealing device is affected by external environmental factors such as temperature and pressure, causing changes in the liquid level due to evaporation or flow. A low liquid level reduces the sealing effect, while an excessively high liquid level increases the power consumption of the desulfurization tower. However, existing technologies lack an adjustment mechanism, making it difficult to adjust the liquid level. To address this deficiency, this application proposes a new solution by incorporating components such as a piston cylinder and a resistance ball. The piston cylinder can raise or lower the liquid level inside the liquid-sealing pipe through liquid suction and discharge, achieving the desired effect of adjusting the liquid level using a piston cylinder and resistance ball. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, there are shortcomings and defects in the existing technology due to the lack of an adjustment mechanism.

[0006] This utility model discloses a high-efficiency liquid seal device for desulfurization of blended super activated carbon, including a base frame. Two liquid seal pipes are arranged on the upper part of the base frame. The outer surface of each liquid seal pipe is fixedly connected to the upper surface of the base frame through a support frame. An adapter is fixedly connected between the two liquid seal pipes. A resistance ball is rotatably connected inside the adapter. The outer surface of the resistance ball has three positioning holes. A piston cylinder is fixedly connected to the upper surface of the adapter. A cylinder is fixedly installed on the top of the piston cylinder. A piston block is fixedly connected to the output end of the cylinder.

[0007] Furthermore, the outer surface of the piston block is provided with equally spaced sealing grooves, and a sealing ring is installed inside each sealing groove.

[0008] The piston cylinder has two air intake windows on its outer surface, and a filter screen is fixedly connected inside each air intake window.

[0009] Furthermore, each of the liquid seal tubes has two first support rings fixedly connected to its outer surface, and the piston cylinder has two second support rings fixedly connected to its outer surface, with each first support ring being fixedly connected to a corresponding second support ring.

[0010] Furthermore, a positioning ring is provided on both the upper and lower sides of the piston block, and both positioning rings are fixedly connected to the inner wall of the piston cylinder.

[0011] Furthermore, the adapter is internally rotatably connected to a worm gear, which is fixedly connected to the outer surface of the resistance ball.

[0012] Furthermore, a worm gear is rotatably connected inside the adapter, a wheel is fixedly installed at one end of the worm gear, a drive motor is fixedly installed on the outer surface of the adapter, and the output end of the drive motor is fixedly connected to the other end of the worm gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up components such as piston cylinder and adapter, and through the cooperation between piston cylinder and sealing ball, enables piston cylinder to achieve liquid suction or discharge by moving piston block, thereby causing the liquid level on both sides of liquid seal pipe to rise or fall, thus achieving the effect of adjusting the liquid level height inside liquid seal pipe by setting piston cylinder and adapter.

[0014] 2. This utility model, by setting up components such as a resistance ball and a worm gear, and through the cooperation between the resistance ball and the worm gear, allows the resistance ball to control the liquid flow rate inside the two liquid seal pipes by rotating, thereby preventing the liquid seal from failing due to rapid flow of liquid height caused by pressure difference. Thus, this utility model achieves the effect of improving sealing performance by setting up components such as a resistance ball and a worm gear. Attached Figure Description

[0017] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Please see Figure 1 , 23, 4, 5, A high-efficiency liquid seal device for desulfurization of blended super activated carbon, comprising a base frame 1, with two liquid seal pipes 2 arranged above the base frame 1. The outer surface of each liquid seal pipe 2 is fixedly connected to the upper surface of the base frame 1 via a support frame 3. A connector 4 is fixedly connected between the two liquid seal pipes 2. A resistance ball 5 is rotatably connected inside the connector 4. The outer surface of the resistance ball 5 has three positioning holes 6. A piston cylinder 7 is fixedly connected to the upper surface of the connector 4. A cylinder is fixedly installed on the top of the piston cylinder 7. A piston block 8 is fixedly connected to the output end of the cylinder. Each liquid seal tube 2 has a liquid level sensor fixedly installed inside. The three positioning holes 6 are interconnected. The positioning holes 6 on both sides correspond to the bottom ends of the two liquid seal tubes 2, and the positioning hole 6 on the top corresponds to the bottom end of the piston cylinder 7. The resistance ball 5 adjusts the flow of liquid inside the two liquid seal tubes 2 and the piston cylinder 7 by rotating. When the bottom end of the liquid seal tube 2 is misaligned with the positioning hole 2, the resistance ball 5 obstructs the flow of liquid inside the two liquid seal tubes 2 and the piston cylinder 7. When the bottom end of the liquid seal tube 2 is aligned with the positioning hole 2, the flow speed of the liquid inside it is relatively faster.

[0019] The outer surface of the piston block 8 is provided with equally spaced sealing grooves 9. Each sealing groove 9 is equipped with a sealing ring 10. The piston block 8 and the sealing ring 10 are made of rubber. The outer surface of each sealing ring 10 is in contact with the inner wall of the piston cylinder 7, thereby improving the airtightness between the piston block 8 and the inner wall of the piston cylinder 7.

[0020] Two air intake windows 11 are opened on the outer surface of the piston cylinder 7. Each air intake window 11 is fixedly connected to a filter screen. The air intake window 11 realizes air intake or exhaust when the piston block 8 moves, thereby stabilizing the pressure inside the piston cylinder 7. The filter screen is used to filter impurities in the air, thereby avoiding damage to the airtightness of the piston cylinder 8.

[0021] Two first support rings 12 are fixedly connected to the outer surface of each liquid seal tube 2, and two second support rings 13 are fixedly connected to the outer surface of the piston cylinder 7. Each first support ring 12 is fixedly connected to the corresponding second support ring 13. The first support rings 12 are symmetrically installed, and the second support rings 13 provide auxiliary support to the piston cylinder 7 through the first support rings 12, thereby improving the stability of the piston cylinder 7.

[0022] A positioning ring 14 is provided on both the upper and lower sides of the piston block 8. Both positioning rings 14 are fixedly connected to the inner wall of the piston cylinder 7. The positioning rings 14 limit the vertical movement distance of the piston block 8. When the piston block 8 moves to the uppermost position, the upper surface of the piston block 8 fits against the lower surface of the positioning ring 14 above it. When the piston block 8 moves to the lowermost position, the lower surface of the piston block 8 fits against the upper surface of the positioning ring 14 below it, thereby improving airtightness.

[0023] The adapter 4 has a worm gear 15 rotatably connected inside. The worm gear 15 is fixedly connected to the outer surface of the resistance ball 5. The connection between the worm gear 15 and the adapter 4 is mechanically sealed. The worm gear 15 is used to drive the resistance ball 5 to rotate.

[0024] The adapter 4 has a worm gear 16 internally rotatably connected. One end of the worm gear 16 is fixedly mounted with a rotating wheel. A drive motor is fixedly mounted on the outer surface of the adapter. The output end of the drive motor is fixedly connected to the other end of the worm gear 16. The connection between the worm gear 16 and the adapter 4 is mechanically sealed. The worm gear 16 meshes with the worm wheel 15. The worm gear 16 is used to drive the worm wheel 15 to rotate. The rotating wheel is used to manually adjust the worm gear 16. The drive motor is used to automatically adjust the worm gear 16.

[0025] The implementation principle is as follows: When the liquid level sensor detects that the liquid level is too high, the cylinder drives the piston block 8 to move upward, and the liquid inside the liquid seal pipes 2 on both sides is drawn into the piston cylinder 7, causing the liquid level inside the liquid seal pipe 2 to drop. When the liquid level is too low, the cylinder drives the piston block 8 to move downward, and the liquid inside the piston cylinder 7 is transported to the inside of the liquid seal pipes 2 on both sides through the positioning hole 6 of the resistance ball 5, causing the liquid level inside the liquid seal pipe 2 to rise. When the liquid level reaches a suitable height, the drive motor starts, and the output end of the drive motor drives the worm gear 16 to rotate. The worm gear 16 drives the worm wheel 15 to rotate, and the resistance ball 5 of the worm wheel 15 rotates. The rotation of the resistance ball 5 causes the positioning holes 6 on both sides to be offset from the bottom end of the corresponding liquid seal pipe 2, making the liquid level height on both sides more stable.

[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
