Description

Technical Field

[0001] This utility model relates to the technology of pollution exhaust gas purification equipment, specifically an odor adsorption and purification device for production exhaust gas. Background Technology

[0002] Industrial production of condiments generates volatile organic compounds and pungent odors, such as oil mist, dust, capsaicin, and water vapor. It usually requires pretreatment, activated carbon adsorption concentration, and catalytic combustion, and activated carbon adsorption-desorption catalytic combustion devices are commonly used.

[0003] For example, the publication (announcement) number: CN217662421U, publication (announcement) date: 2022-10-28, discloses an activated carbon adsorption-desorption catalytic combustion device, which relates to the technical field of waste gas treatment devices. It includes a support frame, an activated carbon adsorption tower fixedly installed at the upper end of the support frame, a desorption pipe fixedly connected at the upper end of the activated carbon adsorption tower, an adsorption pipe fixedly connected at the lower end of the activated carbon adsorption tower, a makeup air fan fixedly installed on one side of the desorption pipe, a purification tower provided on one side of the support frame, a combustion chamber inside the purification tower, and a catalytic chamber inside the purification tower.

[0004] The drawback of existing technology is that the activated carbon used for waste gas adsorption is typically composed of square carbon blocks with equidistantly arranged polygonal vertical holes inside. In actual installation, multiple activated carbon blocks need to be assembled in a rectangular frame, and then the rectangular frame is installed layer by layer in the adsorption chamber. This results in the waste gas passing through multiple layers of frames and only being able to pass through the vertical holes of each activated carbon block sequentially. If the equipment operates for a long time and the exhaust volume exceeds the equipment's processing capacity, the activated carbon near the air inlet of the adsorption chamber suffers greater wear and tear, and the activated carbon further away from the air inlet becomes less effective, while the required desorption cycle of the activated carbon is shortened. This leads to surface damage to some activated carbon during repeated desorption, thus affecting the service life of the activated carbon. However, by changing the airflow direction in the adsorption chamber to allow the waste gas to diffuse evenly or to prioritize the desorption of highly adsorbed activated carbon, the service life of the activated carbon can be effectively extended. Utility Model Content

[0005] The purpose of this invention is to provide an odor adsorption and purification device for production exhaust gas, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An odor adsorption and purification device for production exhaust gas includes an adsorption chamber and multiple carbon frames installed in the adsorption chamber.

[0008] Symmetrical partitions are installed inside the carbon frame to divide the internal space of the carbon frame and form a carbon chamber and ventilation chambers distributed on both sides.

[0009] The ventilation chamber port is movably mounted with an eccentric plate for opening and closing its exhaust.

[0010] As a further description of the above technical solution: a rotating shaft is fixedly installed on the eccentric plate, and a knob is threadedly connected to the end of the rotating shaft.

[0011] As a further description of the above technical solution: the knob abuts against the outer wall of the carbon frame.

[0012] As a further description of the above technical solution: the end of the eccentric plate is provided with a notch located on the outside of the rotating shaft.

[0013] As a further description of the above technical solution: the outer wall of the rotating shaft is movably fitted with a support block located in the notch.

[0014] As a further description of the above technical solution: a guide rod is fixedly installed in the ventilation chamber, and the support block is driven to slide on the guide rod.

[0015] As a further description of the above technical solution: a screw rod that is threadedly connected to the support block is rotatably provided in the ventilation chamber.

[0016] As a further description of the above technical solution: the side wall of the carbon frame is provided with a side hole for the eccentric plate to be inserted and slid.

[0018] As a further description of the above technical solution: multiple activated carbons are installed in the carbon chamber.

[0019] In the above technical solution, the odor adsorption and purification device for production exhaust gas provided by this utility model has the following beneficial effects: by diverting the waste gas entering the adsorption chamber from the ventilation chamber, the adsorption pressure of the current carbon chamber is reduced, and some waste gas is directly transported to the next layer of carbon chamber through the ventilation chamber, effectively dispersing the waste gas evenly. After manually controlling the eccentric plate to open the port of the ventilation chamber, the activated carbon in all carbon chambers can be utilized to the maximum extent. Conversely, when the activated carbon is in desorption mode, the activated carbon that evenly absorbs the waste gas can achieve the desorption function with high efficiency, ensuring the efficiency of activated carbon utilization.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments:

[0029] Example 1

[0030] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, based on the existing frame supporting activated carbon 3, separate airflow channels are created on both sides of the frame, allowing some airflow to bypass the current carbon layer and be directly adsorbed and treated by the activated carbon 3 behind it. Waste gas entering adsorption chamber 1 is diverted through ventilation chamber 23 to reduce the adsorption pressure in the current carbon chamber 22, allowing some waste gas to pass through ventilation chamber 23 and be directly transported to the next carbon chamber 22. This effectively and uniformly diffuses the waste gas, maximizing the utilization of all activated carbon 3 in the carbon chambers 22 when the eccentric plate 4 is manually opened. Conversely, when the activated carbon 3 is in desorption mode, the uniformly absorbed waste gas activated carbon 3 can efficiently achieve desorption, ensuring the utilization efficiency of the activated carbon 3.

[0031] Secondly, if the adsorption chamber 1 fails to open the ventilation chamber 23 in time during adsorption, on the one hand, the ventilation chamber 23 can pick up some of the waste gas blown in through the air inlet and provide some interception function for the particulate matter in the waste gas; on the other hand, during desorption, opening the ventilation chamber 23 in time allows more of the desorption hot gas to flow towards the activated carbon 3 near the air inlet, thereby strengthening the desorption of the activated carbon 3 and also slowing down the protection of the activated carbon 3 that has not been completely adsorbed.

[0032] Specifically, the multiple legs 21 welded to the outer wall of the carbon frame 2 enable the carbon frame 2 to be installed in layers, and metal shielding rings are installed at the corners of the carbon frame 2 facing the air inlet. The purpose is to deliver all the incoming exhaust gas to the carbon frame 2, rather than letting it leak between the outer wall of the carbon frame 2 and the inner wall of the adsorption chamber 1.

[0033] Furthermore, the holes opened on the side wall of the carbon frame 2, such as side holes 24 and end holes 25, are filled with corrosion-resistant and high-temperature resistant rubber, and one side is left open for the component to pass through, so that the rubber overlaps the surface of the component, thereby reducing the loss of some airflow.

[0034] Furthermore, the carbon chamber 22 has multiple square frames, and the activated carbon 3 is assembled and installed in the carbon chamber 22 in order to maximize the function of the activated carbon 3.

[0035] Example 2

[0036] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment details the flip-over ventilation function of the eccentric plate 4. By rotating the shaft 41 to adjust the flip angle of the eccentric plate 4, the airflow discharged from the ventilation chamber 23 flows along the surface of the eccentric plate 4, which can directly transport the waste gas to the rear carbon chamber 22. At the same time, the ventilation chambers 23 can be opened or closed alternately, so that the airflow must flow and cover the entire surface of the current carbon chamber 22 before flowing from the other ventilation chamber 23 to the rear carbon chamber 22, thereby maximizing the function of the current activated carbon 3.

[0037] Specifically, the knob 42 consists of a hexagonal threaded block and a metal block with a rubber ring (made of wear-resistant, corrosion-resistant, and high-temperature resistant rubber material, which is existing technology and will not be described in detail here). After the rotating shaft 41 drives the eccentric plate 4 to stop at a predetermined angle, the knob 42 can be turned to make the rubber ring abut against the outer wall of the carbon frame 2, and the eccentric plate 4 can be fixed by friction to ensure stable oblique ventilation.

[0038] Example 3

[0039] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment details the ability of the eccentric plate 4 to move horizontally. By rotating the screw 52, ​​the support block 5 is moved horizontally within the ventilation chamber 23, thereby opening the eccentric plate 4 horizontally and enabling the ventilation chamber 23 to perform its normal ventilation function.

[0040] Secondly, due to the eccentric setting of the pivot 41, the eccentric plate 4 has a larger opening range on one side, which improves the ability of oblique ventilation, while the notch 43 ensures that the eccentric plate 4 will not interfere with the movement of the support block 5 when it is tilted.

[0041] Specifically, the guide rod 51 is welded to the inner wall of the ventilation chamber 23, and the support block 5 has two holes. One hole has a rounded inner wall and is slidably connected to the guide rod 51; the other hole is threaded and is threadedly connected to the screw rod 52.

[0042] Furthermore, the side hole 24 provides extension space for the eccentric plate 4 to move horizontally, while the end hole 25 provides sliding space for the rotating shaft 41 to move horizontally, ensuring that the eccentric plate 4 can perform translation and flipping operations normally.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
