Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline maintenance, in particular to a repair structure for the soft connection of a smoke exhaust pipeline. Background Technique
[0002] Soot gases such as sulfur dioxide and hydrogen fluoride generated during the electrolysis production of electrolytic cells are transported through the smoke exhaust pipeline under the action of a smoke exhaust induced draft fan. After being collected in a closed negative pressure pipeline, they enter the purification semi-dry desulfurization system for purification and desulfurization, and then are discharged into the atmosphere in accordance with the minimum emission standard of air pollution in the electrolytic metallurgy industry.
[0003] Among them, there are multiple soft connections in the smoke exhaust pipeline. Due to aging over the years, there will be air leakage, resulting in a decrease in the negative pressure value inside the pipeline, affecting the smoke collection effect, reducing the operating efficiency of the smoke exhaust induced draft fan, and replacing the overall soft connection requires shutdown, affecting the normal operation of the equipment and reducing the output value. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to overcome the existing defects, provide a repair structure for the soft connection of a smoke exhaust pipeline, which can complete the repair of the soft connection of the smoke exhaust pipeline without shutdown, ensure that the production capacity is not affected, and can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: a repair structure for the soft connection of a smoke exhaust pipeline, including polyester needle punched felt, the polyester needle punched felt is wound around the outer side of the smoke exhaust pipeline and wrapped at the soft connection position of the smoke exhaust pipeline, and the outer side of the polyester needle punched felt is fixed on the smoke exhaust pipeline by winding with a steel strip.
[0006] As a preferred technical scheme of the utility model, the outer side of the end of the polyester needle punched felt is coated with sealant, and the head and tail ends of the polyester needle punched felt are connected by sealant.
[0007] As a preferred technical scheme of the utility model, the number of the steel strips is two, and the two steel strips are respectively fixed at both ends of the polyester needle punched felt.
[0008] As a preferred technical scheme of the utility model, the outer side of the polyester needle punched felt is painted with high-temperature rust-proof paint.
[0009] Compared with the prior art, the beneficial effect of the utility model is: the repair structure for the soft connection of the smoke exhaust pipeline is fixed by winding the polyester needle punched felt around the outside of the soft connection of the smoke exhaust pipeline and fixing it firmly with a steel strip. The repair of the smoke exhaust pipeline is realized through simple materials, with obvious effects, low maintenance cost, no need for shutdown operation, and greatly improved use convenience.

[0011] Figure 2 This is the unfolded schematic diagram of the polyester needle punched felt.
[0012] In the figure: 1 is the smoke exhaust pipe, 2 is the polyester needle punched felt, 3 is the steel strip, and 4 is the sealant. Specific embodiments
[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0014] Please refer to Figure 1-2 , the present utility model provides a technical solution: a repair structure for the soft connection of a smoke exhaust pipe, including a polyester needle punched felt 2. The polyester needle punched felt 2 is wound around the outer side of the smoke exhaust pipe 1 and wrapped at the soft connection position of the smoke exhaust pipe 1. The outer side of the polyester needle punched felt 2 is wound and fixed on the smoke exhaust pipe 1 through a steel strip 3. Among them, the polyester needle punched felt 2 has a certain softness and good blocking effect, preventing smoke leakage and ensuring the stability of the negative pressure value inside the pipe.
[0015] Further, in order to facilitate the better winding and fixing of the polyester needle punched felt 2 on the outer side of the smoke exhaust pipe 1 and improve the sealing performance of the connection, a sealant 4 is coated on the outer side of the end of the polyester needle punched felt 2, and the head and tail ends of the polyester needle punched felt 2 are connected through the sealant 4.
