Description

Technical Field

[0001] This utility model relates to the technical field of waste gas collection systems, and in particular to an odor collection system for a garbage transfer station. Background Technology

[0002] Waste transfer stations are a crucial component of urban waste management systems, responsible for collecting, temporarily storing, and transporting municipal solid waste. However, the transfer and compression processes generate significant amounts of odorous gases, which not only affect the surrounding environment but may also pose health risks. Therefore, effectively collecting and treating odors from waste transfer stations has become an urgent problem to solve.

[0003] In existing technologies, odor collection and treatment systems at waste transfer stations typically include hoods, exhaust fans, and gas filtration devices. However, these systems often have some shortcomings. For example, poorly designed hoods result in insufficient odor collection; insufficient power or airflow from exhaust fans makes it difficult to effectively remove odors; and gas filtration devices have limited filtration efficiency, failing to completely remove harmful gas components. Furthermore, existing systems typically lack gas detectors and check valves in their collection and extraction pipelines, making it difficult to achieve real-time monitoring of odor components and effectively prevent gas backflow, thus affecting system efficiency and safety.

[0004] To address the aforementioned issues, an improved odor collection system for waste transfer stations is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an odor collection system for waste transfer stations to solve the above-mentioned technical problems, effectively reduce the concentration of odor in the transfer station, and significantly improve the environmental performance and safety of the system.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a garbage transfer station odor collection system, including a transfer chamber and a compression chamber. The compression chamber is equipped with an elevator, and the top of the elevator is equipped with a garbage compression box. Both the transfer chamber and the compression chamber are equipped with multiple gas collection hoods. The exhaust end of the gas collection hood is connected to an exhaust fan through an odor conveying pipe. The exhaust fan is used to convey the odor to the purification treatment unit.

[0007] In one embodiment, the waste compression box is provided with a fall prevention plate, and the fall prevention plate is provided with an openable and closable ventilation structure.

[0008] In one embodiment, the openable and closable ventilation structure includes an air intake and a baffle. A plurality of air intakes are distributed on the anti-fall plate, and the baffle is movably connected to the air intake. The baffle is used to control the opening and closing of the air intake.

[0009] In one embodiment, the exhaust end of the gas collection hood is provided with a regulating valve, which is used to adjust the opening degree of the gas collection hood.

[0010] In one embodiment, a filter screen is arranged at the air inlet end of the gas collection hood.

[0011] In one embodiment, a gas detector and a check valve are installed in the odor delivery pipeline. The gas detector is used to monitor the harmful gas components in the odor in real time, and the check valve is configured to automatically adjust its opening and closing state according to the monitoring data of the gas detector.

[0012] In one embodiment, the inner wall of the odor delivery pipe is coated with an anti-corrosion material.

[0013] In one embodiment, the diameter of the odor delivery pipe between the gas collection hood of the transfer chamber and the exhaust fan is larger than the diameter of the odor delivery pipe between the gas collection hood of the compression chamber and the exhaust fan.

[0014] In one embodiment, the number of odor delivery pipes between the gas collection hood of the transfer chamber and the exhaust fan is greater than the number of odor delivery pipes between the gas collection hood of the compression chamber and the exhaust fan.

[0015] In one embodiment, the lift is a hydraulic lift.

[0016] The present invention achieves the following beneficial effects compared to the prior art:

[0017] The odor collection system for a waste transfer station in this invention includes a transfer chamber and a compression chamber. A lift is installed in the compression chamber, and a waste compression box is mounted on top of the lift. Multiple odor collection hoods are installed in both the transfer and compression chambers. The exhaust ends of the hoods are connected to an exhaust fan via odor delivery pipes. The exhaust fan is used to transport the odor to the purification unit. The presence of odor collection hoods in both the transfer and compression chambers ensures that the hoods cover the entire operating area, improving odor collection efficiency, effectively reducing odor concentration within the transfer station, and significantly enhancing the system's environmental performance and safety.

[0018] This invention can simultaneously and efficiently collect odors from both the transfer chamber and the compression chamber. The underground design of the compression chamber saves on civil engineering space, and its fully enclosed structure effectively suppresses odor volatilization. The application of a check valve reduces unnecessary fan operation, thereby saving energy. The odor collection system for waste transfer stations provided by this invention can efficiently collect and treat odors generated during waste transfer, significantly improving the system's environmental performance and safety, and has broad application prospects.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide an odor collection system for waste transfer stations to solve the problems existing in the prior art, effectively reduce the concentration of odor in the transfer station, and significantly improve the environmental performance and safety of the system.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides an odor collection system for a waste transfer station, including a transfer chamber 1 and a compression chamber 2. A lift 3 is installed inside the compression chamber 2, and a waste compression box 4 is installed on top of the lift 3. Multiple odor collection hoods 5 are installed inside the transfer chamber 1 and the compression chamber 2, respectively, located within the transfer odor collection chamber 6 and the compression odor collection chamber 7. The exhaust ends of the odor collection hoods 5 are connected to an exhaust fan 9 via an odor delivery pipe 8, and the exhaust fan 9 delivers the odor to a purification unit.

[0028] The elevator 3 is a hydraulic elevator, which can stably and evenly raise or lower the height of the garbage compression box 4 to facilitate the compression and transfer of garbage.

[0029] To improve odor collection efficiency, the gas collection hoods 5 in the transfer chamber 1 and compression chamber 2 should be arranged reasonably to cover the entire working area as much as possible, ensuring that odors are effectively collected at the source. At the same time, the design of the gas collection hoods 5 should take into account the convenience of daily maintenance, avoiding cleaning and maintenance difficulties caused by unreasonable equipment layout.

[0030] Example 2

[0031] like Figure 2 As shown, the garbage compression box 4 is equipped with a fall arrestor plate 14, and an openable and closable ventilation structure is provided on the fall arrestor plate 14. Specifically, the ventilation structure includes an air extraction port and a baffle (not shown in the figure). The opening and closing state of the air extraction port is manually controlled to regulate the air circulation inside the compression chamber 2 when the garbage compression box 4 is located inside the compression chamber 2. When the baffle closes the air extraction port, the air circulation inside the compression chamber 2 is restricted. Under the suction action of the exhaust fan 9 through the odor delivery pipe 8, a negative pressure is formed inside the compression chamber 2, and the outside air mainly enters the compression chamber 2 through the gap between the fall arrestor plate 14 and the garbage compression box 4. When the baffle opens the air extraction port, a large amount of outside air directly enters the compression chamber 2 through the air extraction port, which helps to extract the odor inside the compression chamber before the garbage compression box 4 is raised, thereby reducing the odor overflow when the garbage compression box 4 is raised.

[0032] Example 3

[0033] The fume hood 5 is equipped with a regulating valve 12, which can adjust the opening of the fume hood according to actual needs, thereby regulating the collected air volume. A filter screen 13 is arranged at the air inlet end of the fume hood 5 to filter out particulate matter from the odorous gas before it enters the collection pipe, preventing pipe blockage. This design not only improves system efficiency but also reduces maintenance frequency and extends equipment lifespan.

[0034] Example 4

[0035] A gas detector 10 and a check valve 11 are installed inside the odor delivery pipeline 8. The gas detector 10 is used to monitor harmful gas components (such as ammonia, hydrogen sulfide, etc.) in the odor in real time and transmits the monitoring data to the control center. The check valve 11 is intelligent and can automatically adjust its opening and closing state according to the monitoring data of the gas detector 10: it automatically closes when the detected odor concentration reaches a preset threshold (such as exceeding the processing capacity of the purification unit); it automatically opens when the odor concentration is lower than the preset threshold, ensuring the safe and efficient operation of the system.

[0036] Both the gas detector 10 and the check valve 11 are connected to the controller via circuitry. The detection and monitoring of the gas detector 10 and the adjustment of the check valve 11 are both routine control functions of the controller, which are mature technologies in the prior art. The controller can be a commercially available conventional PLC controller, which is also in the prior art, and will not be elaborated further here.

[0037] Example 5

[0038] The inner wall of the odor delivery pipeline 8 is coated with an anti-corrosion material coating, which effectively prevents the pipeline from being corroded due to long-term transportation of odorous gases and extends the service life of the pipeline. The anti-corrosion coating is made of polymer materials, which have excellent corrosion resistance and mechanical strength, and are suitable for long-term, continuous, high-load operating environments.

[0039] Example 6

[0040] The flow rates of the odor delivery pipes 8 in transfer chamber 1 and compression chamber 2 need to be configured differently. Given that transfer chamber 1 is larger than compression chamber 2, the design flow rate of the odor delivery pipe 8 in transfer chamber 1 should be greater than that in compression chamber 2. This can be achieved by increasing the diameter of the odor delivery pipes 8 in transfer chamber 1 (e.g., making the diameter ratio greater than 1:1) or by increasing the number of odor delivery pipes 8 in transfer chamber 1. This design ensures that odors can be extracted more quickly and effectively from the transfer chamber, preventing odor retention and diffusion within the chamber.

[0041] Example 7

[0042] The piping connections between the transfer gas collection chamber 6 and the compression gas collection chamber 7 have been optimized and simplified. Specifically, compared to the complex branching pipes and multi-stage collection methods used in the prior art, this embodiment connects multiple gas collection hoods 5 to a unified odor delivery pipe 8 in a more direct manner. This reduces the number of pipe branches and joints, and minimizes pipe length and bends, thereby significantly reducing internal air resistance and the load requirement of the exhaust fan 9. These measures effectively reduce the complexity of pipeline construction and maintenance, significantly reduce initial construction costs, save energy during operation, and improve overall economic efficiency and system operating efficiency.

[0043] Example 8

[0044] Furthermore, to reduce energy consumption, the operating mode and duct layout of exhaust fan 9 were optimized. Exhaust fan 9 adopts variable frequency control technology to adjust the air volume according to actual needs, thereby reducing energy consumption and improving energy utilization efficiency.

[0045] This utility model discloses an odor collection system for a garbage transfer station. The compression chamber 2 is equipped with a lift 3, and the top of the lift 3 is a garbage compression box 4. Odors are introduced into odor delivery pipes 8 through a gas collection hood 5 installed on the interior wall. A filter screen 13 is installed at the outer end of the gas collection hood 5. The odor delivery pipes 8 of both chambers are connected to an exhaust fan 9, which then transports the odors to a purification unit. A gas detector 10 and a check valve 11 are installed in the odor delivery pipe 8. When the collected odor concentration reaches the load of the purification unit, the check valve 11 closes, and the exhaust fan 9 stops operating. When the collected odor concentration decreases, the check valve 11 opens, and negative pressure delivery continues. This utility model provides a solution that can simultaneously and efficiently collect odors from both the garbage transfer chamber and the compression chamber. The underground compression chamber saves on construction area, and the fully enclosed structure reduces the volatility of odors. The design of the check valve 11 saves on fan operating power, thereby conserving energy. The odor collection system for waste transfer stations provided by this utility model can efficiently collect and treat odors generated during waste transfer, significantly improving the environmental performance and safety of the system, and has broad application prospects.
