Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a vent pipe for chlorine-containing hazardous gases inside a furnace. Background Technology

[0002] Chlorine-containing gases (such as chlorine gas, sodium hypochlorite decomposition products) (etc.) are commonly used for wastewater disinfection, removal of ammonia nitrogen or degradation of organic pollutants (such as cyanide). In the process of conveying chlorine-containing hazardous gases in the furnace, a chlorine-containing hazardous gas furnace inlet gas pipe is required.

[0003] Most venting pipes currently in use are difficult to insulate and securely install. During use, if insulation is difficult, chlorine-containing gases can easily react with water vapor at low temperatures to form liquid acid, causing liquid accumulation on the inner wall of the pipe, obstructing gas flow, and even exacerbating localized corrosion. This results in poor delivery efficiency. Furthermore, the difficulty in securing the pipe in the correct position requires workers considerable time and effort, leading to inconvenient installation and low efficiency. It is also difficult to prevent chlorine-containing gases from corroding the inner wall of the venting pipe. Prolonged gas delivery can cause corrosion, eventually leading to perforation, gas leaks, environmental pollution, and injury, resulting in a short lifespan and poor safety. Utility Model Content

[0004] The purpose of this invention is to provide a vent pipe for chlorine-containing hazardous gases inside a furnace, in order to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vent pipe for a furnace containing chlorine hazardous gas, comprising a pipe body, wherein an insulation installation mechanism is provided on the outer wall of the pipe body, the insulation installation mechanism comprising a first guide rail, wherein the outer wall of the pipe body is provided with a first guide rail and a second guide rail, wherein a guide block is provided inside the first guide rail and the second guide rail, and a first bolt is provided inside the guide block and the first guide rail.

[0006] As a preferred technical solution, the interior of the second guide rail and the interior of the guide block are provided with first bolts, and the outer wall of the guide block is provided with a first flange.

[0007] As a preferred technical solution, a second bolt is provided inside the first flange, and an insulation sleeve is provided on the outer wall of the pipe body.

[0008] As a preferred technical solution, a second flange is provided at one end of the pipe body, and a third bolt is provided inside the second flange.

[0009] As a preferred technical solution, the insulation sleeve is circular in shape, and the shape and size of the insulation sleeve match the shape and size of the tube body.

[0010] As a preferred technical solution, the inner wall of the tube is provided with a ceramic liner, and the shape and size of the ceramic liner match the shape and size of the tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of the insulation installation mechanism, can achieve the functions of heat preservation and fixing of the pipe body. During use, the insulation sleeve is installed by fixing the first flange and the second flange, so that the insulation sleeve insulates the pipe body. The pipe body is installed and fixed in the corresponding position by the cooperation of the first flange and the second bolt, and the second flange and the third bolt. This can avoid the situation where chlorine-containing gas easily reacts with water vapor to form liquid acid at low temperature due to the difficulty of heat preservation of the pipe body, causing liquid accumulation on the inner wall of the pipe body, hindering gas flow, and even causing local corrosion to intensify. This ensures the delivery effect of the vent pipe and avoids the situation where it is difficult to install and fix the pipe body in the corresponding position, which would require workers to spend a lot of time to install and fix the pipe body, thus making the installation inconvenient. This ensures the installation efficiency of the vent pipe.

[0013] 2. This utility model, through the installation of a ceramic liner, can prevent the inner wall of the pipe from being corroded by chlorine-containing hazardous gases. During use, the corrosion resistance of the ceramic liner itself protects the inner wall of the pipe, avoiding the situation where it is difficult to prevent chlorine-containing hazardous gases from corroding the inner wall of the vent pipe, which could lead to long-term gas transportation, corrosion of the inner wall of the vent pipe, perforation of the pipe, leakage of hazardous gases, pollution of the surrounding environment, and harm to personnel. This ensures the service life and safety of the vent pipe. Attached Figure Description

[0019] 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.

[0020] Example: Figure 1 As shown, the present invention provides the following technical solution, including a pipe body 1, an insulation installation mechanism 2 provided on the outer wall of the pipe body 1, and a ceramic lining 3 provided on the inner wall of the pipe body 1.

[0021] Specifically: When pipe body 1 is needed to transport gas, the insulation sleeve 207 must first be installed on the outer wall of pipe body 1, and pipe body 1 must be fixed in the corresponding position. The insulation sleeve 207 is installed on the outer wall of pipe body 1 through the set insulation installation mechanism 2, so that the insulation sleeve 207 insulates pipe body 1. Then pipe body 1 can be used to transport chlorine-containing hazardous gas. During the transportation process, the set ceramic lining 3 prevents chlorine-containing hazardous gas from corroding the inner wall of pipe body 1, thus completing the work.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the pipe body 1 is provided with a heat insulation installation mechanism 2. The heat insulation installation mechanism 2 includes a first guide rail 201. The outer wall of the pipe body 1 is provided with a first guide rail 201 and a second guide rail 204. The interior of the first guide rail 201 and the interior of the second guide rail 204 are provided with guide blocks 202. The interior of the guide blocks 202 and the interior of the first guide rail 201 are provided with first bolts 203. The interior of the second guide rail 204 and the interior of the guide blocks 202 are provided with first bolts 203. The outer wall of the guide blocks 202 is provided with a first flange 205. The interior of the first flange 205 is provided with a second bolt 206. The outer wall of the pipe body 1 is provided with a heat insulation sleeve 207. One end of the pipe body 1 is provided with a second flange 208. The interior of the second flange 208 is provided with a third bolt 209. The heat insulation sleeve 207 is circular in shape, and the shape and size of the heat insulation sleeve 207 match the shape and size of the pipe body 1.

[0023] Specifically: When pipe body 1 is needed to transport gas, the insulation sleeve 207 must first be installed on the outer wall of pipe body 1, and pipe body 1 must be fixed in the corresponding position. At this time, the first bolt 203 is rotated out from the threaded hole in the guide block 202 and the threaded hole in the first guide rail 201. The second guide rail 204 contains a corresponding guide block 202 and a corresponding first bolt 203. The first bolt 203 in the second guide rail 204 is rotated out, and then the guide block 202 is pulled out from the first guide rail 201. The corresponding guide block 202 in the second guide rail 204 is pulled out from the second guide rail 204. The first flange 2... Remove 05, then insert the insulation sleeve 207 into the outer wall of the pipe body 1. Then insert the guide block 202 on the first flange 205 into the first guide rail 201 and the second guide rail 204 respectively. Then fix the guide block 202 with the first bolt 203, so that the first flange 205 and the second flange 208 clamp the insulation sleeve 207 and fix the insulation sleeve 207. Later, the insulation sleeve 207 will be used to insulate the pipe body 1. Then fix the first flange 205 in the corresponding position with the second bolt 206, and fix the second flange 208 in the corresponding position with the third bolt 209, thus completing the insulation installation work.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the inner wall of the tube body 1 is provided with a ceramic liner 3, and the shape and size of the ceramic liner 3 match the shape and size of the tube body 1.

[0025] Specifically, during the transportation process, the ceramic lining 3 is installed to prevent chlorine-containing hazardous gases from corroding the inner wall of the pipe body 1, thereby completing the corrosion prevention work.

[0026] The working principle of this utility model is as follows: When the pipe body 1 is needed to transport gas, the insulation sleeve 207 needs to be installed on the outer wall of the pipe body 1 first, and the pipe body 1 needs to be fixed in the corresponding position. At this time, the first bolt 203 is rotated out from the threaded hole in the guide block 202 and the threaded hole in the first guide rail 201 (the second guide rail 204 has a corresponding guide block 202 and a corresponding first bolt 203, and the first bolt 203 in the second guide rail 204 is rotated out). Then, the guide block 202 is pulled out from the first guide rail 201, and the corresponding guide block 202 in the second guide rail 204 is pulled out from the second guide rail 204. The first flange 205 is removed, and then the insulation sleeve 207 is inserted into the outer wall of the pipe body 1. Insert the guide blocks 202 on the first flange 205 into the first guide rail 201 and the second guide rail 204 respectively, and then fix the guide blocks 202 with the first bolt 203, so that the first flange 205 and the second flange 208 clamp the insulation sleeve 207 and fix the insulation sleeve 207. Later, the insulation sleeve 207 is used to insulate the pipe body 1. Then, fix the first flange 205 in the corresponding position with the second bolt 206, and fix the second flange 208 in the corresponding position with the third bolt 209, thus completing the insulation installation. Then the pipe body 1 can be used to transport chlorine-containing hazardous gases. During the transportation process, the ceramic lining 3 is set to prevent the chlorine-containing hazardous gases from corroding the inner wall of the pipe body 1, thus completing the corrosion prevention work.
