Description

Technical Field

[0001] This utility model belongs to the field of municipal deodorization and ventilation technology, and relates to a deodorizing underground drainage duct structure. Background Technology

[0002] Buried odor control ducts, as the name suggests, refer to odor-causing duct systems buried underground. They are primarily used for collecting and discharging odorous gases in ventilation systems requiring underground wiring, to meet the deodorization and ventilation needs of buildings or facilities. Currently, a common drainage method for buried ducts is to install a sump at the lowest point of the duct, where accumulated water flows by gravity to a drainage well and is then pumped to the sewage network. However, this drainage method has the following drawbacks: when there is insufficient water in the sump, odors can leak to the ground through the drainage pipe to the drainage well. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a deodorizing underground drainage duct structure.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

The odor-deodorizing duct is located beneath the foundation, with a sump at its lower end and a cover plate at its upper end. A valve well is located on the foundation to one side of the odor-deodorizing duct, with a drainage pipe at the lower end of the sump. One end of the drainage pipe extends into the valve well, and an electric valve is installed on the drainage pipe within the valve well. A drainage well is also located on the foundation to one side of the valve well, with the drainage pipe extending into the drainage well after passing through the valve well. A first manhole cover is installed at the upper end of the drainage well.

[0006] Preferably, a liquid level sensor is installed in the water collection pit.

[0007] Preferably, manual valves are installed on the drainage pipes at both ends of the electric valve.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] This embodiment proposes an underground drainage duct structure for deodorization, including a foundation 1, a deodorization duct 2, a drainage well 3, and a valve well 4, with the deodorization duct 2, drainage well 3, and valve well 4 located adjacent to each other within the foundation 1;

[0022] like Figures 1-2 As shown, a deodorizing duct 2 is provided below the foundation 1, and the deodorizing duct 2 is used to collect odorous gases;

[0023] A water collection pit 5 is provided at the lower end of the deodorization duct 2. The water collection pit 5 is used to collect the wastewater inside the deodorization duct 2.

[0024] The upper end of the water collection pit 5 is equipped with a cover plate 6, which is a grid plate, allowing wastewater to pass through freely;

[0025] A valve well 4 is provided on the foundation 1 on one side of the deodorizing air duct 2. A drainage pipe 7 is provided at the lower end of the water collection pit 5. One end of the drainage pipe 7 extends into the valve well 4. An electric valve 9 is provided on the drainage pipe 7 located in the valve well 4. The valve well 4 facilitates the installation and maintenance of valves by staff.

[0026] A drainage well 3 is provided on the foundation 1 on one side of the valve well 4. The drainage pipe 7 extends into the drainage well 3 after passing through the valve well 4. The wastewater inside the sump 5 can flow out through the drainage pipe 7 and enter the drainage well 3, and then enter the subsequent sewage treatment.

[0027] The upper end of the drainage well 3 is provided with a first well cover 11, which seals the drainage well 3, protects the safety of the staff, and prevents debris from entering the drainage well 3.

[0028] Furthermore, a liquid level sensor 12 is installed in the water collection pit 5. When the wastewater in the water collection pit 3 is higher than the warning level, the liquid level sensor 12 triggers a signal, which is transmitted to the electric valve 9. The valve opens automatically, and the wastewater in the water collection pit 5 is discharged into the drainage well 3. When the liquid level is lower than the set value, the electric valve 9 closes to prevent odor leakage.

[0029] Furthermore, manual valves 10 are respectively installed on the drainage pipes 7 at both ends of the electric valve 9. The manual valves 10 are in the normally open state. When the electric valve 9 needs to be disassembled and replaced, the drainage pipes 7 can be shut off using the manual valves 10.

[0030] Furthermore, a first waterproof sleeve 13 is provided on the side wall of the water collection pit 5, which can cooperate with the drainage pipe 7 to prevent wastewater leakage inside the water collection pit 5.

[0031] Furthermore, a second waterproof sleeve 14 is provided on the side wall of the valve well 4, which can cooperate with the drainage pipe 7. The second waterproof sleeve 14 prevents wastewater from seeping into the interior of the valve well 4.

[0032] Furthermore, a third waterproof sleeve 15 is provided on the side wall of the drainage well 3, which can cooperate with the drainage pipe 7. The third waterproof sleeve 15 prevents sewage from leaking from the inside of the drainage well 3.

[0033] Furthermore, an inspection ladder 8 is provided on the side wall of the valve well 4, allowing personnel to enter the interior of the valve well 4 via the inspection ladder 8; a second well cover 16 is provided at the top of the valve well 4, which can seal the valve well 4.

[0034] Furthermore, the end of the drainage pipe 7 that extends into the drainage well 3 is provided with a downward bend 17, which prevents odor from escaping.

[0035] Furthermore, the drainage pipe 7 is inclined downward from the sump 5 to the drainage well 3 at an angle of 0.5-3°. The downwardly inclined drainage pipe 7 facilitates the flow of wastewater inside the sump 5 into the drainage well 3 by its own weight.

[0036] Furthermore, the liquid level sensor 12 is 50-80mm above the bottom of the deodorization duct 2, and there is a certain distance between the liquid level sensor 12 and the bottom of the deodorization duct 2 to avoid backflow of wastewater due to excessively high wastewater level.

[0037] Working principle: When this utility model is in use, the condensate, permeate and other wastewater inside the deodorizing duct 2 will enter the collection pit 5. When the wastewater level in the collection pit 5 rises and triggers the liquid level sensor 12, the signal of the liquid level sensor is transmitted to the electric valve 9, and the valve opens automatically, and the wastewater in the collection pit 5 is discharged into the drainage well 3. When the liquid level is lower than the set value, the electric valve 9 closes to prevent odor leakage. The valve well 4 is used for the installation and maintenance of the electric valve 9 and is isolated from the odorous area to improve the comfort of the working environment.

[0038] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
