Description

Technical Field

[0001] The utility model relates to the field of odor treatment, and more specifically, to an odor collection device. Background Art

[0002] In the process of sewage treatment, the organic matter treatment center plays a crucial role. It can not only treat organic wastes such as sludge, blue-green algae, livestock manure, and straw, but also convert these wastes into biogas through anaerobic digestion processes. The biogas can be further used for power generation or heat production, thus achieving energy self-sufficiency.

[0003] In the organic matter treatment center, microorganisms generate energy by degrading organic substances, releasing gases and heat. Especially in an anaerobic environment, microorganisms carry out anaerobic respiration, and the gases produced contain volatile organic compounds and sulfides, which emit unpleasant odors. At the same time, organic substances containing starch, cellulose, and protein also release a certain amount of sour odor during the degradation process.

[0004] Currently, most odor removal methods adopt centralized treatment by external discharge, but most odor removal devices only use simple suction pipes. These suction pipes are provided with air holes. When the suction fan is started, the odors are drawn out of the treatment center. However, due to the large scale of the treatment center, some areas do not produce odors. During the air extraction process, the odors may enter the air holes along with the airflow, resulting in the diffusion of odors within the treatment center. In addition, the power of the suction fan is limited. If the air holes are fully opened, the air extraction efficiency will decrease. Summary of the Utility Model

[0005] Based on the above technical problems, the utility model proposes an odor collection device.

[0006] An odor collection device includes a collection pipe, a flexible pipe, and an air extraction box. The collection pipe is fixed to the wall through a hoop. One end of the collection pipe is closed, and the other end is connected to the suction fan. The other end of the suction fan is connected to the external discharge pipe. A number of interconnected flexible pipes are provided on the lower side of the collection pipe. The lower ends of the flexible pipes are connected to the air extraction box. The front side of the air extraction box is open. A gas solenoid valve is provided inside the air extraction box. One end of the gas solenoid valve is connected to the flexible pipe, and the other end is connected to the open front side of the air extraction box. The air extraction box is installed on a card seat. An odor sensor is also provided on the lower side of the card seat. Both the odor sensor and the gas solenoid valve are electrically connected to a control device.

[0007] Preferably, the flexible pipe is a telescopic pipe.

[0008] Preferably, the card seat is a U-shaped seat, and clamping grooves are formed on the vertical plates on both sides of the card seat. Clamping plates are arranged on both sides of the air extraction box and are vertically aligned with the clamping grooves. The air extraction box can be installed and fixed by inserting the clamping plates into the clamping grooves.

[0009] Preferably, a screen plate is arranged at the open end.

[0010] Beneficial effects: The collection device is equipped with an air extraction box with a controllable opening degree, and a gas solenoid valve is installed inside the air extraction box to adjust the air flow rate. When the odor sensor detects the odor concentration in this area, it will adjust the air flow rate through the gas solenoid valve, thereby rapidly reducing the odor concentration. In addition, the device is also equipped with a telescopic hose, which can adjust the position of the air extraction box to further improve the accuracy of collection. Description of the Drawings

[0012] Figure 2 shows the structural schematic diagram of the present invention;

[0013] Figure 3 shows the installation structural schematic diagram of the air extraction box. Detailed Embodiments

[0014] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0015] As Figures 1 to 3 shown in the odor collection device, the collection pipe 1 is fixed to the wall through the hoop 2. One end of the collection pipe 1 is closed, and the other end is communicated with the exhaust fan 3. The other end of the exhaust fan 3 is communicated with the exhaust pipe 13. A plurality of interconnected hoses 4 are arranged on the lower side of the collection pipe 1. The hoses 4 are telescopic pipes, and the lower ends of the hoses 4 are connected to the air extraction box 5. The front side of the air extraction box 5 is an open end 11. A gas solenoid valve (not shown) is arranged in the air extraction box 5. One end of the gas solenoid valve is connected to the hose 4, and the other end is communicated with the open end 11 on the front side of the air extraction box 5. The air extraction box 5 is installed on the card seat 6. The card seat 6 is a U-shaped seat. Clamping grooves 10 are formed on the vertical plates on both sides of the card seat 6. Clamping plates 9 are arranged on both sides of the air extraction box 5 and are vertically aligned with the clamping grooves 10. The air extraction box 5 can be installed and fixed by inserting the clamping plates 9 into the clamping grooves 10. The air extraction box 5 is installed in a movable manner, which is not only convenient for maintenance, but also more convenient when the installation position needs to be changed.

[0016] A stench sensor 7 is also provided on the lower side of the card seat 6. The stench sensor can detect the type and concentration of stench. This sensor can adopt a mature instrument on the market. Both the stench sensor 7 and the gas solenoid valve are electrically connected to the control device 8. When the exhaust fan 3 starts, stench can be sucked into the collection pipe 1 from the open end 11 of the air extraction box 5, and then discharged to the stench treatment device through the exhaust pipe.

[0017] Since the power of the exhaust fan 3 is constant, there is often insufficient suction in the hose 4 at a relatively far position, affecting the air extraction efficiency. Moreover, stench may also enter the air extraction box 5 with a greater suction force along with the air flow, causing the stench to spread. Therefore, a gas solenoid valve is provided in the air extraction box 5. The stench sensor 7 sends the type and concentration of stench at this position to the control center, and the control center adjusts the opening degree of the gas solenoid valve to make the air extraction efficiency the same at different positions, so as to ensure that the stench can be quickly sucked into the hose 4 and prevent the stench from flowing extensively in the treatment center. When there is no stench in some areas, the gas solenoid valve is completely closed to improve the air extraction efficiency in other areas.

[0018] In order to prevent foreign objects from flying into the air extraction box 5, a screen plate 12 is provided at the open end 11.

[0019] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
