Abstract

The lower surface of the main air supply pipe is provided with a horizontal air supply pipe, and the lower surface of the horizontal air supply pipe is provided with a support rod, which contacts the bottom surface of the reaction tank. Compared with existing ordinary oxidation air duct networks, this air distribution duct network structure with a special shape and arrangement, through the setting of a pneumatic impeller-type rotating cylinder, allows the pneumatic impeller-type rotating cylinder to rotate by the oxidation air blowing on its impeller, thereby driving the support frame to rotate and stirring the slurry, improving the stirring efficiency, increasing the bonding rate between the oxidation air and the slurry, and preventing the deposition of gypsum byproducts. By opening an air outlet on the upper surface of the support frame, the oxidation air can easily pass through as the support frame passes over the upper surface of the air outlet.

Description

Technical Field

[0001] This utility model relates to the field of oxidation duct technology, specifically to an air distribution duct network structure with a special shape and arrangement. Background Technology

[0002] The oxidation of sulfite is a crucial reaction in the limestone-gypsum wet desulfurization process. Dissolved oxygen in the absorber slurry oxidizes sulfite to sulfate, which ultimately crystallizes and precipitates as gypsum. This process plays a vital role in the quality of the desulfurization slurry, desulfurization efficiency, and gypsum quality. The oxidation system in limestone-gypsum wet desulfurization facilities employs a forced oxidation process. The dissolved oxygen in the desulfurization slurry primarily originates from the oxidizing air injected into the oxidation zone of the absorber tower. Insufficient, excessive, or unevenly distributed oxidizing air can negatively impact the safe and economical operation of the wet desulfurization process.

[0003] In existing oxidation air pipelines, when using oxidation air to react with slurry, the blown air generates bubbles. The existing rotating drum has a limited effect on stirring and mixing materials, failing to effectively accelerate the mixing of oxidation air and slurry. Furthermore, the rotating drum has relatively weak lifting and agitation capabilities for the bottom material during rotation. When the slurry contains a high content of solid particles, sediment easily forms at the bottom.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed an air distribution network structure with a special shape and arrangement. Utility Model Content

[0008] Preferably, the support frame is provided with a rotating sleeve at its end, and the rotating sleeve is rotatably connected to the outer surface of the air supply vertical pipe.

[0014] 1. This utility model, through the arrangement of an air supply main pipe, an air supply horizontal pipe, a support rod, an air supply vertical pipe, an air outlet, a pneumatic impeller-type rotating cylinder, a support frame, a rotating sleeve, and ventilation holes, utilizes the pneumatic impeller-type rotating cylinder. The rotating cylinder is driven by the oxidizing air blowing on its impeller, which in turn drives the support frame to rotate, thus agitating the slurry, improving agitation efficiency, increasing the bonding rate between the oxidizing air and the slurry, and preventing the deposition of gypsum byproducts. The air outlet on the upper surface of the support frame allows the oxidizing air to pass smoothly as it passes over the outlet, preventing interference with the rotation of the support frame.

This utility model, through the setting of scraper, connector, limiting slide rod, sliding sleeve, compression spring and sealing sleeve, the scraper can be driven to fit against the outer surface of the air supply riser when the support frame rotates, so that it can continuously scrape the outer surface of the air supply riser and avoid the slurry residue on the outer surface of the air supply riser forming gypsum plaster and causing damage to the pipeline.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, an air distribution duct network structure with a special shape and arrangement includes an air supply main pipe 1 with an air supply horizontal pipe 101 on its lower surface, and a support rod 102 on the lower surface of the air supply horizontal pipe 101, with the support rod 102 in contact with the bottom surface of the reaction tank. Multiple air supply vertical pipes 2 are installed on the outer surface of the air supply horizontal pipe 101, and multiple air outlets 201 are provided on the outer surface of the air supply vertical pipes 2. The advantage of this arrangement is that, through the arrangement of the air supply vertical pipes 2, oxidation air can be blown out from the inside of the air outlets 201 to react with the slurry.

[0023] Furthermore, a pneumatic impeller-type rotating cylinder 202 is installed in the middle of the surface of the air supply vertical pipe 2, and a support frame 203 is installed on the outer surface of the pneumatic impeller-type rotating cylinder 202. The advantage of this setting is that, through the setting of the pneumatic impeller-type rotating cylinder 202, the pneumatic impeller-type rotating cylinder 202 can be driven to rotate by the pneumatic impeller of the pneumatic impeller-type rotating cylinder 202 by the oxidizing air, which in turn drives the support frame 203 to rotate, thereby stirring the slurry, improving the stirring efficiency, improving the combination rate of oxidizing air and slurry, and preventing the deposition of gypsum byproducts.

[0024] Furthermore, the surface of the support frame 203 is provided with a plurality of ventilation holes 205, and the ventilation holes 205 are located directly above the air outlet 201. The advantage of this arrangement is that by opening the air outlet 201 on the upper surface of the support frame 203, the oxidation air can pass smoothly when the support frame 203 passes over the upper surface of the air outlet 201, thus avoiding the oxidation air from interfering with the rotation of the support frame 203.

[0025] Furthermore, a rotating sleeve 204 is provided at the end of the support frame 203, and the rotating sleeve 204 is rotatably connected to the outer surface of the air supply vertical pipe 2. The advantage of this setting is that the support frame 203 can be driven to rotate synchronously by the rotating sleeve 204.

[0026] like Figures 3-4 As shown, a sliding sleeve 303 is provided on the upper surface of the support frame 203, and a limiting slide rod 302 is slidably installed through the surface of the sliding sleeve 303. The advantage of this setting is that the scraper 3 can be limited by the setting of the limiting slide rod 302, so as to prevent it from deviating during the movement.

[0027] Furthermore, a connector 301 is provided on the lower surface of the limiting slide bar 302, and a compression spring 304 is provided on the upper outer surface of the limiting slide bar 302. The advantage of this arrangement is that, through the setting of the compression spring 304, the scraper 3 can be driven to fit against the outer surface of the air delivery vertical pipe 2 by resetting compression, so that it can come into more thorough contact with the slurry.

[0028] Furthermore, a scraper 3 is provided on the lower surface of the connector 301, and the scraper 3 is in contact with the outer surface of the air supply riser 2. The advantage of this arrangement is that, by setting the scraper 3, when the support frame 203 rotates, the scraper 3 can be driven to fit against the outer surface of the air supply riser 2, so that it can continuously scrape the outer surface of the air supply riser 2, avoiding the formation of gypsum plaster on the outer surface of the air supply riser 2 and causing damage to the pipeline.

[0029] Furthermore, a sealing sleeve 305 is provided above the compression spring 304, and the lower surface of the sealing sleeve 305 is in close contact with the upper surface of the support frame 203. The advantage of this setting is that the sealing sleeve 305 can seal and protect the compression spring 304, preventing the compression spring 304 from being damaged by contact with the slurry.

[0030] Working Principle: When using this specially shaped and arranged air distribution duct network structure, the oxidation air is first diverted from the main air supply pipe 1 to the horizontal air supply pipe 101, and then delivered to the vertical air supply pipe 2. When the oxidation air is ejected from the outlet 201 of the vertical air supply pipe 2, it immediately undergoes an oxidation reaction with the slurry. Simultaneously, the ejected oxidation air impacts the pneumatic impeller inside the pneumatic impeller-type rotating cylinder 202, driving the cylinder to rotate using hydrodynamic power. As the pneumatic impeller-type rotating cylinder 202 rotates, the connected support frame 203 rotates synchronously along the outer surface of the vertical air supply pipe 2, changing the flow angle of the slurry through agitation, accelerating the fusion efficiency of the slurry and oxidation air, promoting the formation of gypsum by-products, and effectively preventing the deposition of gypsum by-products at the bottom of the reaction tank.

[0031] To address the issue of slurry residue on the outer surface of the air supply riser 2, during the rotation and agitation of the slurry by the support frame 203, the limiting slide bar 302, installed through its surface, continuously applies downward pressure under the restoring force of the compression spring 304, pushing the scraper 3 to tightly adhere to the outer surface of the air supply riser 2. In this way, the scraper 3 can promptly remove the adhering residual slurry, ensuring the surface of the air supply riser 2 is clean and preventing the hardening of slurry residue from affecting equipment performance and operating efficiency. This is the working principle of this air distribution pipeline structure with its unique shape and arrangement.
