Description

Technical Field

[0001] The utility model relates to the technical field of tail gas adsorption, in particular to a tail gas adsorption device. Background Art

[0002] Industrial exhaust refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within enterprise factories. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead and mercury, beryllium, smoke and productive dust. When discharged into the atmosphere, they will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have a cumulative effect, which will more seriously endanger human health. Different substances will have different effects.

[0003] When treating these waste gases, traditional activated carbon adsorption devices mostly add activated carbon inside a shell to adsorb the exhaust gas. However, during use, it was found that the activated carbon layer was too high, but the exhaust gas passed through the activated carbon path was short, which resulted in the activated carbon adsorption effect on the exhaust gas not being obvious enough, and the production cost was also high. Therefore, we proposed a new adsorption device. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a tail gas adsorption device with the following beneficial effects:

[0017] The exhaust gas adsorption device is constructed by opening an S-shaped through-hole inside a fixing base and filling the through-hole with activated carbon particles. A filter screen is arranged at the top and bottom of the fixing base to seal the upper and lower ends of the through-hole to prevent the activated carbon particles from falling. The exhaust gas then enters from the air inlet, passes through the through-hole, is adsorbed by the activated carbon particles, and is then discharged from the air outlet. This reduces the use of activated carbon and the cost of using activated carbon, but increases the flow path of the exhaust gas in the activated carbon, making the adsorption effect more obvious.

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0028] In the related art, the activated carbon layer is too high, but the exhaust gas passes through a short path of the activated carbon, which results in the activated carbon's adsorption effect on the exhaust gas being not obvious enough and the filtration cost being high.

[0029] In order to solve the problems in the related technology to a certain extent, an embodiment of the present application provides an exhaust gas adsorption device. When it needs to be used, it is only necessary to add a through hole with an S-shaped path inside the cylinder 11 and fill the through hole with activated carbon particles, which can increase the exhaust gas flow path and increase the adsorption effect.

[0030] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0031] Combine Figure 1-Figure 3An embodiment of the present application provides an exhaust gas adsorption device, including an adsorption assembly 1; the adsorption assembly 1 includes: an air outlet 12 is provided at the top of a cylinder 11; an air inlet 13 is provided at the bottom of the cylinder 11; a fixing seat 14 is provided inside the cylinder 11; a through hole 15 is opened inside the fixing seat 14, and activated carbon is provided inside the through hole 15; a filter screen 16 is provided at the top and bottom of the fixing seat 14.

[0032] When in use, first fill the inside of the through hole 15 with activated carbon particles, and the filter screen 16 is set at the top and bottom of the fixing seat 14 to block the upper and lower ends of the through hole 15 to prevent the activated carbon particles from falling from the upper and lower ends of the through hole 15. Then the exhaust gas enters from the air inlet 13, passes through the through hole 15, is adsorbed by the activated carbon particles, and then discharged from the air outlet 12, which reduces the use of activated carbon and reduces the cost of using activated carbon, but increases the flow path of the exhaust gas in the activated carbon, making the adsorption effect more obvious.

[0033] Specifically, the fixing seat 14 is a cylindrical solid structure with a through hole 15 in the middle. The fixing seat 14 and the cylinder body 11 can be connected by welding or bolting.

[0034] In some embodiments, the through hole 15 is S-shaped, and the length of the through hole 15 is greater than the height of the fixing base 14. The S-shaped design prevents the exhaust gas from flowing straight through the through hole 15, thereby increasing the flow path of the exhaust gas without increasing the height of the activated carbon.

[0035] In some embodiments, a frame 17 is provided on the outer side wall of the filter 16, and the frame 17 is connected to the fixing base 14 by bolts. The filter 16 and the frame 17 are welded and fixed to the fixing base 14 by bolts.

[0036] In some embodiments, the adsorption assembly 1 is provided with an auxiliary assembly 2, which includes a filter plate 21 disposed inside the cylinder 11 and below the cylinder 11. The filter plate 21 is provided to prevent large particles of impurities in the exhaust gas from clogging the filter screen 16. Because the exhaust gas flows through the through-hole 15 and has a limited flow area, when the filter screen at the bottom of the through-hole 15 becomes clogged, it will affect the flow of the exhaust gas in the through-hole 15 at that location, resulting in the inability of the activated carbon particles inside the through-hole 15 to filter the exhaust gas, thereby reducing the exhaust gas adsorption efficiency.

[0037] In some embodiments, a tube 22 is provided inside the cylinder 11, the tube 22 passing through the cylinder 11, and a nozzle 23 is provided on the outer wall of the tube 22. The tube 22 is connected to a high-pressure gas tank. When the adsorption assembly 1 is not in operation, the nozzle 23 is used to spray and clean the filter plate 21 to facilitate the next use.

[0038] Specifically, the high-pressure gas tank belongs to the prior art and is not shown in the accompanying drawings.

[0039] In some embodiments, the tube body 22 is rotatably connected to the cylinder body 11, and a rotary joint 24 is provided at one end of the tube body 22. The tube body 22 is connected to the high-pressure gas tank through the rotary joint 24, and the tube body 22 is also rotatably connected to the cylinder body 11, so that the filter plate 21 can be cleaned more easily by rotating the tube body 22.

[0040] In some embodiments, the tube body 22 is located between the filter plate 21 and the fixing base 14. The tube body 22 is located between the filter plate 21 and the fixing base 14. Under the filtration of the filter plate 21, the influence of impurities on the tube body 22 is reduced, and the filter plate 21 is swept downward to prevent impurities from passing through the filter plate 21 and blowing toward the filter screen 16.

[0041] In some embodiments, a door plate 25 is provided on the outer wall of the cylinder 11, and a sealing ring is provided between the door plate 25 and the cylinder 11. The door plate 25 facilitates the nozzle 23 to clean out impurities at the bottom of the cylinder 11 after cleaning the filter plate 21.

[0042] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0043] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
