DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The shell and tube design is adopted, and multiple bundle tubes with activated carbon filter blocks inside are set in the shell, which can filter the medium evenly and the heat on the activated carbon filter blocks is not easy to be conducted away. Figure 1-4 As shown, the present invention discloses a tubular activated carbon adsorption device, comprising a shell 1, a feed pipe 7, and a discharge pipe 8. Tube sheets 101 are welded to both ends of the shell 1. Tube sheets 102 are evenly spaced and sleeved through the tube sheets 101. Activated carbon filter blocks 103 are embedded in the tubes 102.

[0024] One end of the shell 1 is fixed with a first bundle box 2 by bolts, and the end of the shell 1 away from the first bundle box 2 is fixed with a second bundle box 3 by bolts. A reflux assembly 4 is provided on the top of the shell 1, and the reflux assembly 4 includes a reflux pipe 401 located at the top of the shell 1, and a first valve 402 is sleeved on one end of the reflux pipe 401, and a one-way valve 404 is connected to the other end of the reflux pipe 401 through a threaded groove. The top of the reflux pipe 401 is connected to a flow meter 403 through a threaded groove.

[0025] During use, the medium enters the shell 1 and is blocked by the tube sheet 101, flows into the bundle tube 102 and is adsorbed by the activated carbon filter block 103. Opening the first valve 402 allows the medium to flow back through the reflux pipe 401 for further adsorption.

[0026] For example, Figure 1 As shown, the present invention further includes that a feed pipe 7 is welded on the top of the first bundle box 2 , and a discharge pipe 8 is welded on the top of the second bundle box 3 .

[0027] When in use, the medium flows into the first bundle box 2 through the shell 1 , and the adsorbed medium in the second bundle box 3 flows out through the discharge pipe 8 .

[0028] For example, Figure 1 、 Figure 4 As shown, the present invention also includes that both ends of the return pipe 401 are respectively connected to one side of the feed pipe 7 and the discharge pipe 8 through pipe joints, and the detection end of the flow meter 403 is located inside the return pipe 401.

[0029] When in use, the medium in the discharge pipe 8 flows back into the feed pipe 7 through the return pipe 401 , and the flow meter 403 can detect and display the flow of the medium in the return pipe 401 .

[0030] For example, Figure 3As shown, the present invention also includes: a filter screen 201 is fixed to the inside of the first bundle box 2 close to the shell 1 by bolts; a storage pipe 202 is welded to the bottom of the first bundle box 2; and an end cover 203 is connected to the bottom of the storage pipe 202 through a threaded groove.

[0031] When in use, the filter screen 201 can filter the medium entering the housing 1 , and the particles and the like that fall into the storage pipe 202 can be taken out by opening the end cover 203 .

[0032] For example, Figure 1 As shown, the present invention further includes that one end of the second bundle box 3 is connected to a connecting pipe 5 through a pipe joint, and one end of the connecting pipe 5 is connected to a second valve 6 through a threaded groove.

[0033] When in use, the second valve 6 is opened to allow the medium in the second bundle box 3 to flow out through the connecting pipe 5, so that personnel can use detection equipment to detect the medium.

[0034] For example, Figure 1 As shown, the present invention further includes supports 9 welded to both ends of the bottom of the shell 1 .

[0035] When in use, the support 9 is used to support the housing 1 .

[0036] When the utility model is in use, the medium flows into the first bundle box 2 through the feed pipe 7 and is filtered by the filter screen 201 in the first bundle box 2. The filter screen 201 can filter out the particles in the medium, and the filtered particles fall into the storage pipe 202. The end cover 203 can be opened to clean the particles.

[0037] The filtered medium enters the shell 1 and is blocked by the tube sheet 101, then enters the multiple bundled tubes 102, where it is adsorbed and filtered by the activated carbon filter blocks 103. The bundled tubes 102 protect the activated carbon filter blocks 103, preventing their heat from being easily transferred out.

[0038] The medium adsorbed by the activated carbon filter block 103 flows into the second bundle box 3 and flows out through the discharge pipe 8;

[0039] Personnel can install the sensor of the detection equipment on the second valve 6. When the second valve 6 is opened, the medium absorbed in the second bundle box 3 flows out through the connecting pipe 5 and the second valve 6, which is convenient for the detection equipment to detect it.

[0040] When a person opens the first valve 402, the medium in the discharge pipe 8 can flow into the feed pipe 7 through the return pipe 401 so that it can be adsorbed again. The one-way valve 404 can prevent the medium in the feed pipe 7 from flowing into the return pipe 401. The flow meter 403 can detect and display the flow rate of the medium flowing in the return pipe 401.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
