Description

Technical Field

[0001] This utility model belongs to the field of coal gas purification technology, specifically relating to a desulfurization regeneration tank liquid level adjustment and foam flotation device. Background Technology

[0002] Coal gas purification refers to the treatment of coal gas containing various impurities to purify it to meet national emission standards and other specific industrial requirements. Coal gas purification has wide applications, primarily including coal gas power generation, energy conversion, and chemical manufacturing, thereby significantly improving energy efficiency and environmental protection. Coal gas purification methods are divided into physical, chemical, and biological methods. Physical methods are suitable for processes such as separation, washing, desulfurization, and dehydration. Chemical methods refer to the use of chemical reactions for coal gas purification. Biological methods involve the application of microorganisms in the coal gas purification process. During coalification, approximately one-third of the sulfur is converted into sulfides such as H2S, becoming impurities in the coal gas. If H2S is not removed from the coal gas, it will severely corrode equipment during transportation; as a civilian fuel, it will pollute the environment and harm human health; and as a metallurgical fuel, it will seriously affect the quality of steel products. In PDS desulfurization, after the desulfurization liquid is regenerated in the regeneration tank, sulfur exists in the form of sulfur foam, which is suspended in large quantities at the top of the regeneration tank. In order to facilitate the flotation of sulfur foam and adjust the reaction liquid level in the regeneration tank, the common method is to increase the liquid level of the desulfurization liquid. This method seriously affects the water balance of the desulfurization system.

[0003] Existing desulfurization regeneration tank level adjustment and foam flotation devices, such as patent number CN222499053U, are characterized by comprising an inner cylinder, a connecting pipe, an outer cylinder, a lifting screw, a limiting groove, a pressure equalizing rod, and a horizontal rod. A desulfurization liquid outlet pipe is located on one side of the bottom of the outer cylinder. The top of the outer cylinder is connected to a top cover, and the bottom of the outer cylinder is sealed to the connecting pipe. The bottom of the connecting pipe is the desulfurization liquid inlet, which is connected to the desulfurization regeneration tank via a flange. An inner cylinder is located inside the connecting pipe, and a horizontal rod is connected to the top of the inner cylinder. The horizontal rod is connected to the bottom end of the lifting screw, and its length is greater than the diameter of the connecting pipe. Several pressure equalizing rods are vertically connected to the outer diameter of the inner cylinder, and the ends of the pressure equalizing rods are located in the limiting grooves on the inner wall of the outer cylinder and slide up and down with the lifting screw.

[0004] Although this patent can control the liquid level of the regeneration tank by adjusting the height of the inner cylinder, in use, an electric screw jack is usually required to drive the screw rod to rotate to adjust the height of the inner cylinder. However, traditional desulfurization regeneration tank liquid level adjustment and foam flotation devices have difficulty controlling the position of the inner cylinder inside during adjustment, which may affect the effect of regeneration tank liquid level control and reduce the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a desulfurization regeneration tank level adjustment and foam flotation device, which aims to solve the problem that existing desulfurization regeneration tank level adjustment and foam flotation devices usually require an electric screw jack to drive the screw rod to rotate to adjust the height of the inner cylinder during use. However, traditional desulfurization regeneration tank level adjustment and foam flotation devices have difficulty controlling the position of the inner cylinder during adjustment, which may affect the level control effect of the regeneration tank and reduce the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization regeneration tank liquid level adjustment and foam flotation device, including a connecting pipe, an outer cylinder fixedly connected to the top of the connecting pipe, an upper cover connected to the top of the outer cylinder, a balance air inlet provided on the top of the upper cover, a threaded rod threaded through the top of the upper cover, and a connecting rod rotatably connected to one end of the threaded rod.

[0007] The bottom of the connecting rod is fixedly connected to an inner cylinder, the outer wall of the outer cylinder is fixedly connected to a desulfurization liquid outlet pipe, one end of the threaded rod is fixedly connected to a connecting block, the outer wall of the connecting block has an annular groove, the inner side of the annular groove is rotatably connected to an annular sleeve, the outer wall of the annular sleeve is fixedly connected to a mounting base, one end of the mounting base is fixedly connected to a first connecting sleeve, the inner side of the first connecting sleeve has an indicator rod, the outer wall of the indicator rod is provided with a scale, and the top of the connecting rod is fixedly connected to a second connecting sleeve.

[0008] In a preferred embodiment of the desulfurization regeneration tank liquid level adjustment and foam flotation device of this utility model, one end of the indicator rod extends through the upper cover into the inner cylinder.

[0009] In a preferred embodiment of the desulfurization regeneration tank level adjustment and foam flotation device of this utility model, the through end of the indicator rod is located inside the second connecting sleeve.

[0010] In a preferred embodiment of the desulfurization regeneration tank level adjustment and foam flotation device of this utility model, a spring is movably connected inside the mounting base, one end of the spring is connected to a movable block, one end of the movable block is fixedly connected to a locking pin, and one end of the indicator rod is provided with a locking groove.

[0011] In a preferred embodiment of the desulfurization regeneration tank level adjustment and foam flotation device of this utility model, one end of the locking pin extends through into the interior of the first connecting sleeve, and the through end of the locking pin is adapted to the size of the locking groove.

[0012] As a preferred embodiment of the desulfurization regeneration tank liquid level adjustment and foam flotation device of this utility model, the annular sleeve can form an elastic engagement structure with the scale through the mounting seat, spring, movable block, locking pin, first connecting sleeve, and locking groove.

[0015] By moving the movable block with a lever, the locking pin retracts, and then the indicator rod is inserted into the first connecting sleeve, then through the top cover, and finally into the second connecting sleeve. At this point, releasing the lever causes the locking pin to pop out under the action of the spring and insert into the locking pin, thus fixing the indicator rod in place. Then, by using an electric screw lift to drive the threaded rod to rotate, the inner cylinder height is adjusted. During this process, the annular sleeve rotates along the inside of the annular groove, allowing the top of the connecting rod to move the indicator rod up and down together. The height of the inner cylinder can then be accurately observed according to the position of the scale, thereby improving the practicality of the device.

[0016] By moving the movable block with the lever, the locking pin retracts, at which point one end of the locking pin disengages from the slot. Then, by pulling the indicator rod upward, it can be removed from the outer cylinder, thus enabling convenient disassembly of the indicator rod for subsequent maintenance.
