Description

Technical Field

[0001] This utility model relates to the field of air collection technology, specifically to a ground-based odor collection system. Background Technology

[0002] Currently, in the collection and treatment of odors from above-ground spaces, such as sludge produced in sewage treatment plants, after being filtered and dewatered in a sludge dewatering machine, the dewatered sludge needs to be transported to a sludge loading room and then transported by sludge truck to a sludge recycling and treatment facility. However, the sludge loading room is usually quite large. When loading sludge, the entire space needs to be opened to allow the truck to enter. Due to the large size of the loading space, the odor spreads over a wide area, and the efficiency of the odor extraction by the fan is low, making it difficult to quickly remove the odor. Furthermore, the odor easily spreads to the outside, causing pollution. Utility Model Content

[0003] This invention provides a ground-based odor collection system, which aims to quickly remove odors and reduce the spread of odors.

[0004] This utility model is achieved through the following technical solution: a ground space odor collection system, including a loading room, a collection hopper inside the loading room, an outward-opening door at the entrance and exit of the loading room, an inward-opening door inside the loading room, the inward-opening door dividing the loading room into a loading space and a transportation space, the collection hopper being located in the loading space, an internal suction unit for odor extraction being provided in the loading space, and an external suction unit for odor extraction being provided in the transportation space.

[0005] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0006] This design incorporates both outward-opening and inward-opening doors. The inward-opening door divides the loading area into two independent spaces. After the outward and inward-opening doors are opened, the sludge-loading truck enters the loading space, and then the doors are closed. This confines the odor generated during the sludge's journey from the hopper to the truck to the loading space. Because the inward-opening door partitions the large space of the loading room, reducing its volume, the internal suction unit can be activated to more efficiently remove the odor from the loading space, resulting in higher odor removal efficiency.

[0007] In this solution, the inward-opening door effectively reduces the spread of odors after it is closed, confining the odors to a small area, thereby improving suction efficiency and reducing suction power, making it more energy-efficient.

[0008] In addition, the external suction unit in this solution can suck up the small amount of odor that escapes into the transport space, further reducing the spread of odor to the outside of the loading room.

[0009] Furthermore, it also includes a main duct, and the air outlets of both the internal and external suction units are connected to the main duct.

[0010] The main pipeline in this solution can transport the odorous gases extracted by the internal and external suction units to the designated location.

[0011] Furthermore, the external suction unit is installed on top of the transport space, and the internal suction unit is installed on top of the loading space.

[0012] In this design, both the external and internal suction units are installed on the top of the loading chamber, which reduces space occupation.

[0013] Furthermore, a side suction hood is installed on the side wall of the loading space, and multiple side suction ports are opened on one side of the side suction hood. A connecting pipe is connected between the side suction hood and the main pipe. A main fan is installed on the main pipe, and the main fan is installed on the side of the connecting pipe away from the side suction hood.

[0014] In this solution, a side suction hood is installed on the side wall of the loading space. The side suction hood and the internal suction unit at the top work together to provide suction, which can cover a larger suction range within the loading space and improve the efficiency of odor removal.

[0015] Furthermore, the internal suction unit includes an internal fan, and the external suction unit includes an external fan. The air outlets of both the internal fan and the external fan are connected to the main duct.

[0016] The internal and external suction units in this solution use fans for suction, which results in good suction performance.

[0017] Furthermore, the external suction unit also includes an external top suction cover, which is installed on the top of the transport space, and the external fan is installed on the external top suction cover; the internal suction unit also includes an internal top suction cover, which is installed on the top of the loading space, and the internal fan is installed on the internal top suction cover.

[0018] The external and internal top suction hoods in this design can guide the odor during suction, allowing the odor to be drawn in more concentratedly.

[0019] Furthermore, the side suction cover is in the shape of an arc plate, and the inside of the side suction cover is hollow.

[0020] The side suction hood in this design is shaped like an arc plate, which has a higher efficiency in capturing and sucking up odors. It can guide the airflow into the side suction hood, reduce the escape of odors caused by airflow turbulence, and achieve a better odor suction effect.

[0021] Furthermore, the internal suction unit includes an internal top suction cover, the bottom of which has multiple top suction ports. One end of the internal top suction cover is perpendicular to and connected to the side suction cover, and the other end of the internal top suction cover extends in the direction close to the inward opening door.

[0022] In this design, the internal top suction hood and the side suction hood are perpendicular to each other and connected, forming a figure-7 structure. One end of the internal top suction hood extends along the direction close to the inward-opening door, which expands the top coverage area and thus the range of odor extraction, allowing rising odors to be extracted more effectively. The combination of the side suction hood and the internal top suction hood expands the overall suction range, enabling more comprehensive extraction of odors in the loading space and handling of gases that cannot rise completely to the top of the loading room.

[0023] Furthermore, the side suction port is located at the upper part of the side suction cover, and the top of the inner top suction cover is connected to a guide plate, which is inclined from top to bottom away from the side suction cover.

[0024] The guide plate in this design can guide the odor into the side suction hood, reducing the amount of odor escaping.

[0025] Furthermore, the bottom of the loading chamber has multiple exhaust channels, and the bottom of the loading chamber is also equipped with an exhaust pipe. The bottom of the multiple exhaust channels is connected to the exhaust pipe, and one end of the exhaust pipe is located on the outside of the loading chamber and is connected to an exhaust fan.

[0026] In this solution, by turning on the exhaust fan, the odor can be discharged through multiple exhaust channels. This further improves the comprehensiveness of odor extraction, making the top, side walls and bottom of the loading space designed to extract odor, with a wider coverage area. This further improves the odor extraction effect and reduces odor residue. At the same time, the exhaust channel at the bottom can handle settled odors and reduce the residue of settled odors.
