Description

Technical Field

[0001] This utility model relates to an odor treatment system, specifically a high- and low-concentration odor treatment system. Background Technology

[0002] For large-scale projects such as waste-to-energy incineration, food waste and kitchen waste treatment, and medical waste treatment, the volume of odor treatment is substantial, and the processing air volume of a single odor treatment unit is limited. Therefore, two or more odor treatment units are needed to meet the odor treatment requirements. Furthermore, the composition, properties, and concentration of odor gases vary in different areas, resulting in varying degrees of corrosion to equipment and pipelines. If only one odor treatment system is used, the equipment and pipelines must be designed and selected to withstand the worst environments and meet the highest standards. Therefore, large-scale projects often consider installing two odor treatment systems to treat high- and low-concentration odors separately.

[0003] In projects already in operation, to ensure the continuous operation of the odor treatment system, only a very few high-performing projects have set up backups for both the odor treatment equipment and the deodorizing fans, such as... Figure 1 As shown. Most projects only have a backup for the deodorizing fan, which has a higher failure rate, such as... Figure 2 As shown, even so, the odor treatment system still faces shutdown if the odor treatment equipment malfunctions. In addition, the calculated odor air volume for each area was too large during the initial design, and the equipment selection also took into account the redundancy factor, resulting in the selection of oversized odor treatment equipment and deodorizing fans. The deodorizing fans can meet the deodorization effect even under low-frequency operation.

[0004] In summary, the existing technology has the following problems:

[0005] (1) For the very few projects that have both odor treatment equipment and deodorizing fans set up backups, the project investment cost is too high and the backup equipment is used in a relatively low frequency, which is economically unreasonable.

[0006] (2) For most projects that only set up backups for deodorizing fans with high failure rates, the odor treatment system cannot operate once the odor treatment equipment fails.

[0007] (3) During the initial design, the odor treatment equipment and deodorizing fan were selected with a large margin. The deodorizing fan operated at a low frequency and had low efficiency. Utility Model Content

[0008] Purpose of the utility model: The purpose of this utility model is to provide an economical high- and low-concentration odor treatment system that can operate efficiently while ensuring the odor treatment effect.

[0009] Technical Solution: This utility model discloses a high and low concentration odor treatment system, comprising a low concentration odor treatment system and a high concentration odor treatment system. The low concentration odor treatment system includes a low concentration odor inlet pipe, a first odor treatment device, and a first deodorizing fan connected in sequence. The high concentration odor treatment system includes a high concentration odor inlet pipe, a second odor treatment device, and a second deodorizing fan connected in sequence. A first air valve is installed on the low concentration odor inlet pipe, and a second air valve is installed on the high concentration odor inlet pipe. A first branch is connected between the inlet of the first air valve and the outlet of the second air valve, and a third air valve is installed on the first branch. A second branch is connected between the inlet of the second air valve and the outlet of the first air valve, and a fourth air valve is installed on the second branch.

[0010] Furthermore, the low-concentration odor inlet pipe, the high-concentration odor inlet pipe, the first branch, the second branch, and the four air valves are integrated into a box. The box is provided with four interfaces on the outside, which are respectively used to connect the low-concentration odor, the high-concentration odor, and to connect the first odor treatment equipment and the second odor treatment equipment. The box, the pipes and air valves inside the box, and the four interfaces on the outside of the box constitute a switching device.

[0011] Furthermore, the air valve is an electric air valve.

[0012] Furthermore, the outlet of the first deodorizing fan is connected to a first discharge pipe for high-altitude discharge, and the outlet of the second deodorizing fan is connected to a second discharge pipe for high-altitude discharge.

[0013] Furthermore, the first odor treatment device is connected to the first deodorizing fan via a first intermediate pipeline, and the second odor treatment device is connected to the second deodorizing fan via a second intermediate pipeline.

[0014] Furthermore, the odor treatment equipment employs activated carbon adsorption odor treatment equipment, chemical washing odor treatment equipment, plant liquid washing odor treatment equipment, biological deodorization odor treatment equipment, or photocatalytic oxidation odor treatment equipment to perform single-stage treatment of odors.

[0015] Furthermore, the odor treatment equipment combines two or more of the following: activated carbon adsorption odor treatment equipment, chemical washing odor treatment equipment, plant liquid washing odor treatment equipment, biological deodorization odor treatment equipment, and photocatalytic oxidation odor treatment equipment, to perform multi-stage treatment of odors.

[0016] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0017] This invention utilizes four air valves to enable the odor treatment equipment and deodorizing fan in both low-concentration and high-concentration odor treatment systems to serve as backups for each other. Compared to high- and low-concentration odor treatment systems where both odor treatment equipment and deodorizing fans are set as backups, or where only the deodorizing fan is set as a backup, this invention eliminates the need for backup equipment in both low-concentration and high-concentration odor treatment systems by utilizing the spare capacity of the odor treatment equipment and deodorizing fan, thus saving investment.

[0018] By utilizing the spare capacity of four air valves, odor treatment equipment, and deodorizing fans, not only can the low-concentration odor treatment system and the high-concentration odor treatment system serve as backups for each other, but the operation of the deodorization system is also optimized while ensuring the deodorization effect. For example, one set of odor treatment equipment and deodorizing fans can be used to handle both high and low concentration odors, thereby improving the efficiency of the deodorizing fan, ensuring the efficient operation of the deodorization system, and saving operating costs.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 3 As shown, this utility model embodiment provides a high and low concentration odor treatment system, including a low concentration odor treatment system and a high concentration odor treatment system.

[0024] The low-concentration odor treatment system includes a low-concentration odor inlet pipeline, a first odor treatment device, a first intermediate pipeline, and a first deodorizing fan connected in sequence. The outlet of the first deodorizing fan is connected to a first discharge pipeline for high-altitude emission.

[0025] The high-concentration odor treatment system includes a high-concentration odor inlet pipeline, a second odor treatment device, a second intermediate pipeline, and a second deodorizing fan connected in sequence. The outlet of the second deodorizing fan is connected to a second emission pipeline for high-altitude emission.

[0026] Odor treatment equipment employs activated carbon adsorption, chemical washing, plant-based liquid washing, biological deodorization, or photocatalytic oxidation to treat odors in a single stage.

[0027] In another embodiment, the odor treatment equipment uses a combination of two or more of the following: activated carbon adsorption odor treatment equipment, chemical washing odor treatment equipment, plant liquid washing odor treatment equipment, biological deodorization odor treatment equipment, and photocatalytic oxidation odor treatment equipment, to perform multi-stage treatment of odor.

[0028] A first damper M1 is installed on the low-concentration odor inlet pipe, and a second damper M2 is installed on the high-concentration odor inlet pipe. A first branch line connects the inlet of the first damper M1 and the outlet of the second damper M2, and a third damper M3 is installed on the first branch line. A second branch line connects the inlet of the second damper M2 and the outlet of the first damper M1, and a fourth damper M4 is installed on the second branch line. The dampers are electrically operated, facilitating remote pipeline on / off control.

[0029] In this embodiment, the low-concentration odor inlet pipe, the high-concentration odor inlet pipe, the first branch pipe, the second branch pipe, and four air valves are integrated into a single housing. Four interfaces are provided on the exterior of the housing for connecting the low-concentration odor, the high-concentration odor, and the first and second odor treatment devices, respectively. Thus, the housing, its internal pipes and air valves, and the four external interfaces constitute a switching device. This switching device, as a finished product, can be easily connected to both high- and low-concentration odor treatment systems.

[0030] The working principle of the high and low concentration odor treatment system is as follows.

[0031] Operating Condition 1: Open the first air valve M1 and the second air valve M2, and close the third air valve M3 and the fourth air valve M4. Low-concentration odor gas is drawn into the first odor treatment equipment by the first deodorizing fan, and high-concentration odor gas is drawn into the second odor treatment equipment by the second deodorizing fan.

[0032] Operating Condition 2: Open the first air valve M1 and the fourth air valve M4, and close the second air valve M2 and the third air valve M3. Both low-concentration and high-concentration odor gases are drawn into the first odor treatment equipment by the first deodorizing fan.

[0033] Operating Condition 3: Open the second air valve M2 and the third air valve M3, and close the first air valve M1 and the fourth air valve M4. Both low-concentration and high-concentration odor gases are drawn into the second odor treatment equipment by the second deodorizing fan.

[0034] This invention utilizes four air valves to enable switching between three operating conditions.
