Description

Technical Field

[0001] This utility model relates to the field of adjustable liquid level controllers, specifically a wet oxidation method sleeve-type mechanical lifting rod device for adjusting the desulfurization liquid level balance. Background Technology

[0002] In wet oxidation desulfurization systems, after the desulfurization liquid completes gas-liquid mass transfer adsorption in the desulfurization tower, the rich desulfurization liquid at the bottom of the tower is pumped into the bottom of the regeneration tank. There, it undergoes oxidation and regeneration with the air at the bottom, generating elemental sulfur foam. Due to the influence of operating flow rates, when the liquid level is not balanced: if the regeneration tank level is too low, the suspended sulfur foam will accumulate at the top of the regeneration tank, forming elemental sulfur that will settle and accumulate at the bottom, affecting regeneration oxidation; if the regeneration tank level is too high, excessive desulfurization re-liquid entering the foam tank will affect the settling and solid-liquid separation in the foam tank. The regenerated lean desulfurization liquid is layered at the top 2 / 3 of the regeneration tank. Currently, the industry uses a structure where the outlet is located at the top 2 / 3 of the regeneration tank, and a regulating valve controls the outlet flow. This process causes a large amount of regenerated lean desulfurization liquid to enter the lean liquid tank when the system is shut down, resulting in liquid overflow from the lean liquid tank.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

The lean liquid is discharged to the lean liquid tank through the overflow port. After the system stops, the servo motor loses its axial positioning ability, and the weight of the inner tube causes the threaded rod to drive the adjusting nut to rotate, and the inner tube sinks to seal the outlet.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] This utility model provides a sleeve-type mechanical lifting rod device for adjusting the desulfurization liquid level balance in a wet oxidation process. When in use, the sleeve-type mechanical lifting rod device stabilizes the sulfur foam on the liquid surface. The lean liquid is discharged to the lean liquid tank 101 through the overflow port 402. After the system stops, the servo motor 300 loses its axial positioning ability, and the weight of the inner tube 400 causes the threaded rod 305 to drive the adjusting nut to rotate, and the inner tube 400 sinks to seal the outlet.

[0033] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the wet oxidation method sleeve-type mechanical lifting rod regulating desulfurization liquid level balancing device of this utility model. Please refer to [link / reference]. Figures 1-6 This embodiment of a wet oxidation method sleeve-type mechanical lifting rod regulating desulfurization liquid level balance device includes:

[0034] The outer cylinder 200 has an outlet pipe 207 embedded and welded to its bottom end, and an inlet pipe 205 is welded and fixed to the bottom end of the side wall of the outer cylinder 200. A liquid level sensor 203 is embedded and fixed to the top end of the inlet pipe 205. The liquid level sensor controls the forward and reverse rotation of the servo motor through the controller. The working principle of the liquid level sensor and the controller is existing technology and will not be described in detail here.

[0035] The inner tube 400 is embedded in the outer cylinder 200 and fits snugly onto the outlet pipe 207. The top of the inner tube 400 has an overflow port 402 arranged in a ring array. The overflow port 402 has an inclination angle of 25°-35° and the edges are polished and passivated.

[0036] The lifting assembly includes a servo motor 300 fixed to the top of the outer cylinder 200 and a threaded rod 305 connected to the inner tube 400. The bottom end of the servo motor 300's shaft is fixedly connected to an adjusting nut tube 304 threaded onto the threaded rod 305. When the sleeve-type mechanical lifting rod regulating desulfurization liquid level balance device is in use, the rich desulfurization liquid enters the regeneration tank 100, where air oxidation generates sulfur foam. The liquid level sensor 203 monitors the liquid level. When the liquid level is low, the servo motor 300 drives the adjusting nut tube 304. When rotating forward, the threaded rod 305 drives the inner tube 400 to descend, and the overflow port 402 is lowered. When the liquid level is high, the servo motor 300 drives the adjusting nut tube 304 to rotate in the opposite direction, and the threaded rod 305 drives the inner tube 400 to rise, raising the overflow port 402, so that the sulfur foam is stably accumulated on the liquid surface. The lean liquid is discharged to the lean liquid tank 101 through the overflow port 402. After the system stops, the servo motor 300 loses its axial positioning ability, and the weight of the inner tube 400 causes the threaded rod 305 to drive the adjusting nut to rotate, and the inner tube 400 sinks to seal the outlet.

[0037] Combination Figures 1-6 This embodiment describes a wet oxidation method sleeve-type mechanical lifting rod regulating desulfurization liquid level balance device. The specific usage process is as follows: When in use, the sleeve-type mechanical lifting rod regulating desulfurization liquid level balance device allows the rich desulfurization liquid to enter the regeneration tank 100. Air oxidation generates sulfur foam. The liquid level sensor 203 monitors the liquid level. When the liquid level is low, the servo motor 300 drives the adjusting nut tube 304 to rotate forward, and the threaded rod 305 drives the inner tube 400 to descend, lowering the overflow port 402. When the liquid level is high, the servo motor 300 drives the adjusting nut tube 304 to rotate in the opposite direction, and the threaded rod 305 drives the inner tube 400 to rise, raising the overflow port 402, causing the sulfur foam to accumulate stably on the liquid surface. The lean liquid is discharged through the overflow port 402 to the lean liquid tank 101. After the system stops, the servo motor 300 loses its axial positioning capability, and the weight of the inner tube 400 causes the threaded rod 305 to rotate, causing the inner tube 400 to sink and seal the outlet.

[0038] In this embodiment, a first flange 204 is integrally formed on the inlet pipe 205, and a second flange 206 is integrally formed on the bottom end of the outlet pipe 207. A regeneration tank 100 and a lean liquid tank 101 are respectively provided on one side of the inlet pipe 205 and the outlet pipe 207. Bolts are installed in a ring array on the sidewalls of the first flange 204 and the second flange 206. Multiple bolts are threaded into the sidewalls of the regeneration tank 100 and the lean liquid tank 101. A connecting plate 201 is integrally formed on the top end of the outer cylinder 200, and a top plate 302 is fixedly installed through the connecting plate 201. Bolts are installed in a ring array on the top end of the top plate 302. Nuts are threaded through the bottom end of multiple bolts through the connecting plate 201. Support rods 303 are welded and fixed in a ring array on the top end of the top plate 302. Multiple support rods 303 are... A mounting plate 301 is fixed between the three parts. A servo motor 300 is fixed to the top of the mounting plate 301. An adjusting nut tube 304 is rotatably inserted into the mounting plate 301 through a bearing. A sealing block 403 with an annular structure that fits against the outlet tube 207 is bonded to the inner wall of the inner tube 400. A sleeve 401 is fixed to the top of the inner tube 400. The bottom end of the threaded rod 305 is embedded in the sleeve 401. Fastening bolts 306 located at both ends of the sleeve 401 are threaded onto the threaded rod 305. The inner wall of the settling tube and the outer wall of the outlet tube are tightly connected through the sealing block. The friction generated by the tight connection of the settling tube can prevent the threaded rod fixed at its top from rotating synchronously with the adjusting nut tube. In order to further prevent axial rotation, a protrusion that slides into the inner wall of the outer cylinder can be set on the sleeve.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
