Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a quantitative conveying device for organic waste gas treatment. Background Technique

[0002] Organic waste gas treatment refers to the work of treating industrial waste gas generated in industrial sites, such as dust particles, flue gas soot, odor gas, toxic and harmful gases. Common waste gas purification includes factory soot waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc.

[0003] In the process of waste gas treatment, pipelines are needed to convey the waste gas in a closed manner. However, the waste gas often contains corrosive components, which corrode the inside of the conveying device, thereby shortening the service life and having poor sealing performance. Therefore, a quantitative conveying device for organic waste gas treatment is proposed to facilitate the adjustment of the waste gas flow rate while improving the sealing performance of the conveying equipment and extending its service life. Content of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a quantitative conveying device for organic waste gas treatment to facilitate the adjustment of the waste gas flow rate while improving the sealing performance of the conveying equipment and extending its service life.

[0005] The technical solution adopted by the utility model to solve its technical problems is a quantitative conveying device for organic waste gas treatment, which includes an outer protective pipe, flanges, a handwheel, a valve rod, an inner gas conveying pipe and an anti-rust layer. Flanges are provided at both ends of the outer protective pipe. An activated carbon filter screen is provided at one end of the flange. A handwheel is provided at the top of the outer protective pipe. An inner gas conveying pipe is arranged inside the outer protective pipe. Support columns are provided on both sides of the bottom of the outer protective pipe.

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0020] In order to facilitate adjusting the flow rate of the waste gas while improving the sealing performance of the conveying device and prolonging its service life, as Figures 1-3 shown, the quantitative conveying device for organic waste gas treatment of the present utility model includes an outer protective pipe 1, a flange 2, a handwheel 7, a valve stem 8, an inner conveying pipe 12 and a rust-proof layer 13. Flanges 2 are provided at both ends of the outer protective pipe 1. An activated carbon filter screen 6 is provided at one end of the flange 2. A handwheel 7 is provided at the top of the outer protective pipe 1. An inner conveying pipe 12 is provided inside the outer protective pipe 1. Support columns 15 are provided on both sides of the bottom of the outer protective pipe 1.

[0021] During use, connect multiple sections of the outer protective pipe 1, snap the sealing ring 4 into the sealing groove 3 to prevent gaps from appearing between the flanges 2, and then install the activated carbon filter screen 6 in the installation groove 5 through bolts. The outer protective pipe 1 wraps the inner gas transmission pipe 12 to play a role in mobile protection and prevent damage;

[0022] When waste gas flows into the inner gas transmission pipe 12, rotate the handwheel 7 to drive the valve rod 8 and the butterfly plate 10 to adjust the angle, control the passing amount and flow rate of the waste gas. The sealing gasket 9 and the anti-slip strip 11 fill the gap between the butterfly plate 10 and the inner gas transmission pipe 12 to prevent waste gas leakage;

[0023] The rust-proof layer 13 and the anti-corrosion coating 14 of the inner gas transmission pipe 12 can prevent the corrosive gas contained in the waste gas from corroding and oxidizing the pipe wall, thereby extending the service life of the inner gas transmission pipe 12.

[0024] In order to filter fine particles in the waste gas, for example, as Figure 1 、 Figure 2 shown, the present utility model further includes that a sealing groove 3 is provided on the periphery of one side surface of the flange 2, a sealing ring 4 is provided in the sealing groove 3, an installation groove 5 is provided on the inner wall of the flange 2, and the activated carbon filter screen 6 is installed in the installation groove 5 through screws.

[0025] During use, snap the sealing ring 4 into the sealing groove 3 to prevent gaps from being generated between the mutually contacting flanges 2, and then filter fine particles in the waste gas flowing through by the activated carbon filter screen 6.

[0026] For example, as Figure 1 、 Figure 2 shown, the present utility model further includes that the bottom of the handwheel 7 is fixedly connected to the valve rod 8 through a bolt, and the valve rod 8 passes through the outer protective pipe 1 through a reserved opening.

[0027] During use, drive the valve rod 8 to rotate through the handwheel 7 to facilitate adjusting the gas passing amount and flow rate.

[0029] During use, drive the valve rod 8 and the butterfly plate 10 to rotate to be parallel to the position of the gas transmission pipe through the handwheel 7 to allow the gas to pass through, and then rotate the handwheel 7 to close it. The sealing gasket 9 and the anti-slip strip 11 block the gap between the butterfly plate 10 and the inner wall of the inner gas transmission pipe 12 to avoid gas leakage.

[0031] When in use, the anti-rust layer 13 made of polyurethane material can effectively protect the inner gas transmission pipe 12 from being corroded by harmful gases in the waste gas, and prevent cracks from appearing on the surface of the gas transmission pipe 12, resulting in waste gas leakage.

[0032] Exemplarily, as Figure 1 、 Figure 3 shown, the utility model further includes that an anti-corrosion layer 14 is arranged on the inner surface of the anti-rust layer 13, and the anti-corrosion layer 14 is made of epoxy resin material.

[0033] When in use, the anti-corrosion layer 14 made of epoxy resin material covers the outer surface of the anti-rust layer 13 to prevent the corrosive medium gas carried in the waste gas from contacting it, resulting in corrosion.

[0034] When the utility model is in use, multiple sections of the outer protective pipes 1 are connected, the sealing ring 4 is clamped into the sealing groove 3 to avoid gaps between the flanges 2, and then the activated carbon filter screen 6 is installed in the installation groove 5 through bolts. The outer protective pipe 1 wraps the inner gas transmission pipe 12 inside, playing a role of mobile protection to avoid damage;

[0035] When the waste gas flows into the inner gas transmission pipe 12, the hand wheel 7 is rotated to drive the valve stem 8 and the butterfly plate 10 to adjust the angle, so as to control the passing amount and flow rate of the waste gas. The sealing gasket 9 and the anti-slip strip 11 fill the gap between the butterfly plate 10 and the inner gas transmission pipe 12 to prevent waste gas leakage;

[0036] The anti-rust layer 13 and the anti-corrosion coating 14 of the inner gas transmission pipe 12 can prevent the corrosive gas carried in the waste gas from corroding and oxidizing the pipe wall, thereby prolonging the service life of the inner gas transmission pipe 12.
