Description

Technical Field

[0001] This utility model relates to the field of desulfurization tower technology, specifically a desulfurization tower capable of endoscopic inspection. Background Technology

[0002] In aluminum electrolysis production, due to technological advancements and environmental requirements for flue gas emissions, electrolysis flue gas purification systems need to be equipped with desulfurization systems. As the service life of desulfurization systems in various aluminum electrolysis enterprises increases, uncontrollable factors such as aging, erosion, peeling, shedding, and mechanical damage occur in the glass flakes on the inner wall of the desulfurization tower, internal components such as demisters and spray layers. This leads to varying degrees of aging and damage to the glass flakes on the inner wall of the desulfurization tower, internal demisters, and spray layers, affecting the safe and stable operation of the desulfurization system. Therefore, regular inspections of the desulfurization tower's interior become an essential control measure. Currently, internal inspections of the desulfurization tower involve stopping the desulfurization system, opening manholes, and allowing personnel to enter for inspection. This method requires closing the flue valves, shutting down the desulfurization tower, and performing confined space work, resulting in significant consumption of manpower, material resources, and financial resources, and also carries the risk of instantaneous exceedances of emission standards for electrolysis flue gas. Utility Model Content

[0003] The main purpose of this utility model is to provide a desulfurization tower that can be inspected internally, so as to solve the problem that the desulfurization tower needs to be shut down and confined space operations are required for internal inspection of the existing desulfurization tower, resulting in a large consumption of manpower, material resources and financial resources, and bearing the risk of instantaneous exceedance of electrolysis flue gas emissions.

[0004] To achieve the above objectives, this utility model provides a desulfurization tower capable of endoscopic inspection, comprising a tower body, an inspection tube fixedly connected to the side wall of the tower body, the outer end of the inspection tube being located outside the tower body and the inner end being located inside the tower body; a duckbill-shaped blocking bag is provided inside the inspection tube to prevent flue gas from being discharged outside the tower body, the blocking bag being made of PTFE rubber; one end of the blocking bag has a round opening connected to the inspection tube facing outwards from the tower body, and the other end has a slender flat opening facing inwards from the tower body.

[0005] Furthermore, the inspection tube includes an outer tube and an inner tube; the inner end of the inner tube is located inside the outer tube and is fixedly connected to the blocking bag, while the outer end is located outside the outer tube; the outer wall of the inner tube is provided with a convex ring, which is fixedly connected to the outer end of the outer tube by a nut.

[0006] Furthermore, a washer is provided at the point where the convex ring abuts against the outer tube.

[0007] Furthermore, an end cap is detachably and securely connected to the outer end of the inspection tube.

[0008] This invention, by incorporating an inspection tube, facilitates the insertion of an industrial endoscope into the desulfurization tower for inspection. The inspection does not require shutting down the desulfurization tower or requiring workers to enter the confined space. Furthermore, by including a blocking bag, the inspection tube is blocked when the industrial endoscope is inserted, minimizing the amount of flue gas from the desulfurization tower escaping through the inspection tube.

[0009] This invention features an outer tube and an inner tube, with the blocking bag connected to the inner tube. The inner tube can be disassembled and removed, facilitating the replacement of the blocking bag. Attached Figure Description

The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention.

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown in the embodiment of this utility model, a desulfurization tower capable of endoscopic inspection is provided, including a tower body 1. An inspection tube 2 is fixedly connected to the side wall of the tower body 1. The outer end of the inspection tube 2 is located outside the tower body 1, and the inner end is located inside the tower body 1. A duckbill-shaped blocking bag 4 is provided inside the inspection tube 2 to prevent flue gas from being discharged outside the tower body. The blocking bag 4 is made of PTFE rubber. One end of the blocking bag 4 has a round opening 402 connected to the inspection tube 2 and facing the outside of the tower body 1, and the other end has a slender flat opening 401 facing the inside of the tower body 1. An end cap 3 is detachably and fixedly connected to the outer end of the inspection tube 2. During inspection, the end cap 3 is removed, an industrial endoscope is inserted, and after inspection, the industrial endoscope is removed and the end cap 3 is installed to prevent flue gas inside the tower body 1 from coming out of the inspection tube 2.

[0015] The structure of the baffle bag 4 can reduce the obstruction of the inspection tube 2 when the industrial endoscope is inserted for inspection, thereby minimizing the discharge of flue gas from the tower body 1 through the inspection tube 2. The principle is as follows: when the industrial endoscope is inserted into the tower body 1 through the baffle bag 4, the airflow inside the tower body 1 will compress the duckbill-shaped baffle bag 4, causing the flat opening 401 to close tightly under the action of the airflow, thereby reducing the discharge of flue gas from the tower body 1 through the inspection tube 2.

[0016] In some embodiments, the inspection tube 2 includes an outer tube 201 and an inner tube 202; the inner end of the inner tube 202 is located inside the outer tube 201 and is fixedly connected to the blocking bag 4, while the outer end is located outside the outer tube 201; the outer wall of the inner tube 202 is provided with a protruding ring 202a, which is fixedly connected to the outer end of the outer tube 201 by a nut 203; a washer 204 is provided at the contact point between the protruding ring 202a and the outer tube 201.

[0017] By setting an outer pipe 201 and an inner pipe 202, and connecting the blocking bag 4 to the inner pipe 202, the inner pipe 202 can be disassembled and removed, making it convenient to replace the blocking bag 4; the connection between the outer pipe 201 and the inner pipe 202 is sealed to prevent flue gas from being discharged outward from the connection between the outer pipe 201 and the inner pipe 202.

[0018] The above embodiment, by setting up the inspection tube 2, facilitates the insertion of an industrial endoscope into the interior of the tower body 1 for inspection. During the inspection, it is not necessary to shut down the desulfurization tower, nor is it necessary for workers to enter the confined space, thereby reducing the consumption of manpower, material resources, and financial resources, and reducing the risk of instantaneous exceedance of electrolysis flue gas emissions.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the 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 principles of this utility model should be included within the protection scope of this utility model.
