Description
Technical Field
[0001] The utility model relates to the technical field of odor treatment, in particular to a front-end quantitative and uniform spraying pipeline type deodorizing device. Background Art
[0002] In the composting plant, aerobic composting fermentation pretreatment (from the transportation of materials to the composting plant to the heating of materials to 55°C after inoculation of composting bacteria) will produce a large amount of NH3 and a small amount of H2S, dimethyl sulfide, trimethylamine, and VOC, among which NH3 is the main odor component; these odor components will have an impact on the environment and need to be treated.
[0003] The odor treatment method in the prior art is usually to centrally transport the odor in the factory area to the terminal deodorization system through pipelines. Since the odor components generated in different factory areas are different (such as breeding areas, sewage treatment areas, sludge and manure treatment areas, organic fertilizer production areas, etc.), the odor concentration and odor components transported to the terminal deodorization system are relatively complex. The mixed odor increases the difficulty of odor treatment. It is necessary to arrange multiple deodorization facilities for odors with different components at the deodorization terminal, and the design volume of a single deodorization facility will be increased, thereby increasing the footprint of the terminal deodorization system and the construction cost of the terminal deodorization system. The treatment is more troublesome. In addition, the odor generated in some factory areas may contain harmful gases such as pathogens. The technology of centralized transportation terminal treatment may cause the hidden danger of the spread of harmful gases such as pathogens. Therefore, a front-end quantitative uniform spraying pipeline deodorization device is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that the odor concentration and odor components transported to the terminal deodorization system in the prior art are relatively complex, and the mixed odor increases the difficulty of odor treatment. It is necessary to arrange multiple deodorization facilities at the deodorization terminal for odors with different components, and the design volume of a single deodorization facility will be increased, thereby increasing the floor space of the terminal deodorization system and the construction cost of the terminal deodorization system, which is a relatively troublesome problem to deal with. At the same time, it also solves the problem that the odor generated in some factory areas may contain harmful gases such as pathogens, and the technology of centralized transportation and terminal treatment may cause the hidden danger of the spread of harmful gases such as pathogens.

[0033] See also Figure 1-2In this embodiment, a front-end quantitative uniform spraying pipeline deodorizing device includes an air inlet pipeline 1 and an air outlet pipeline 2. The air inlet pipeline 1 is used to connect to a place where odor is generated, and the air outlet pipeline 2 is used to connect to a terminal deodorizing system. A deodorizing pipeline 3 is installed between the air inlet pipeline 1 and the air outlet pipeline 2. The diameter of the deodorizing pipeline 3 is 2-4 times that of other pipelines, which can reduce the flow rate of the odor and increase the contact time. The air inlet pipeline 1, the air outlet pipeline 2 and the deodorizing pipeline 3 constitute a pipeline deodorizing system, which is controlled by a PLC controller 16.
[0034] It is understandable that in actual application, the pipeline deodorization system can be applied to various odor-generating places, so as to facilitate the targeted selection of different agents for deodorization pretreatment of odors generated by different odor source workshops, and finally transport them to the terminal deodorization system in a centralized manner, so as to reduce the deodorization concentration and complexity of odor components at the deodorization terminal, thereby reducing the use of acid, alkali and other agents in the terminal deodorization system.
[0035] In this embodiment, a first bypass valve 11 is fixedly installed on the gas outlet pipeline 2, and the first bypass valve 11 is provided to facilitate the adjustment of the flow rate of the gas outlet pipeline 2. At the same time, a stench recycling pipeline 12 is fixedly installed on the gas outlet pipeline 2 through a three-way connection, and the stench recycling pipeline 12 is connected to the stench source equipment of the stench source workshop. A second bypass valve 13 is fixedly installed on the stench recycling pipeline 12, and the flow rate of the stench recycling pipeline 12 is conveniently adjusted by the second bypass valve 13. When the stench pretreated by the deodorization pipeline 3 reaches the reuse standard, the gas outlet pipeline 2 can be connected to the workshop where the stench can be reused through the stench recycling pipeline 12, so that the reusable stench is returned to the reuse workshop, achieving the effect of recycling, saving resources, and improving the practicality of the device.
[0036] In this embodiment, a circulating spray system for deodorization is provided in the deodorization pipeline 3, and the circulating spray system includes a liquid collection pipe 8 installed below the deodorization pipeline 3, a medicine adding box 4 connected to the liquid collection pipe 8, a spray pump 5 connected to the medicine adding box 4, a medicine pipe 6 connected to the output end of the spray pump 5, and a water mist nozzle 7 installed on the outside of the medicine pipe 6 and extending to the inside of the deodorization pipeline 3. Among them, a third bypass valve 15 is fixedly installed on the medicine pipe 6, and the flow rate of the medicine pipe 6 is conveniently adjusted by the third bypass valve 15. At the same time, the number of water mist nozzles 7 is set to multiple, and the multiple water mist nozzles 7 are staggered and sprayed obliquely downward relative to each other, with an angle of 60-90°, and the distance between each two adjacent water mist nozzles 7 is 0.5-1.5m. The multiple water mist nozzles 7 can realize efficient spraying of the odor inside the deodorization pipeline 3, ensuring that the medicine spray sprayed by the water mist nozzle 7 can fully contact with the odor, thereby ensuring the deodorization effect. In addition, the number of liquid collecting pipes 8 is set to be multiple, and the multiple liquid collecting pipes 8 are evenly distributed along the bottom of the deodorizing pipe 3, and the distance between every two adjacent liquid collecting pipes 8 is 0.5-1.5m. Through the multiple liquid collecting pipes 8, the sprayed agent inside the deodorizing pipe 3 can be collected and transported to the inside of the drug adding box 4, thereby achieving the effect of recycling, saving resources, and improving the practicability of the device.
[0037] It is understandable that the agent added inside the agent adding box 4 can be targetedly added for spraying acid, alkali, biological or plant deodorizing agents, etc. according to the different main components of the odor transported in the current deodorizing pipeline 3.
[0038] It should be added that a folding plate 14 is fixedly installed inside the deodorizing pipe 3, and the number of the folding plates 14 is set to be multiple. The multiple folding plates 14 are evenly distributed along the inside of the deodorizing pipe 3, and the distance between every two adjacent folding plates 14 is 0.5-1.5m. The folding plates 14 are set to change the flow direction of the odor inside the deodorizing pipe 3, thereby increasing the residence time of the gas inside the deodorizing pipe 3, so that the deodorizing agent spray can fully contact the odor, thereby ensuring the deodorizing effect.
[0039] In this embodiment, an odor monitor 9 is installed on the side of the outlet pipe 2 close to the deodorization pipe 3. The odor monitor 9 can monitor the concentration of the main indicators of the odor after pretreatment through the deodorization pipe 3. During the monitoring process, if the odor concentration exceeds the standard, the system will automatically alarm, and the PLC controller 16 will control the third bypass valve 15 to open wider, thereby increasing the amount of deodorant sprayed by the water mist nozzle 7 on the agent pipe 6, and alarm to remind the operator to add new agents to the dosing box 4 in time. When the odor monitor 9 detects that the odor concentration is reduced, the sensor will automatically feedback to the PLC controller 16, and then control the third bypass valve 15 to open smaller, thereby reducing the amount of agent sprayed. When the odor concentration reaches the reuse standard after pretreatment, the odor can be reused, and the second bypass valve 13 is opened. The pretreated odor is sent to the reuse odor source workshop through the odor reuse pipe 12. Excess odor or odor that does not need to be reused will directly lead to the terminal deodorization system through the outlet pipe 2.
[0040] In addition, an ultraviolet irradiation lamp 10 is installed on the air outlet pipe 2. The ultraviolet irradiation lamp 10 can be used to disinfect and sterilize some air outlet pipes 2 that transport odors containing pathogenic bacteria.
[0041] The working principle of the above embodiment is:
[0042] When the present application is in use, an air inlet pipe 1 and an air outlet pipe 2 are set to collect the odor of the corresponding odor source workshop. Before the odor is passed to the terminal deodorization system, the corresponding treatment agent is added to the inside of the dosing box 4 according to the main components of the odor transported in the current deodorization pipe 3. The odor in the deodorization pipe 3 is sprayed through the water mist nozzle 7 under the transportation of the spray pump 5 and the agent pipe 6, thereby realizing targeted deodorization pretreatment of the odor at the front end of the odor collection, so as to reduce the deodorization concentration of the deodorization terminal and the complexity of the odor components, facilitate subsequent processing, and help to meet the deodorization standards.
[0043] The electrical components mentioned in the text are all electrically connected to the PLC controller 16 and the power supply. The PLC controller 16 is a conventional known device, and there is an existing public power connection technology. Therefore, the specific structure and working principle thereof will not be described in detail in the text.
