Description

Technical Field

[0001] This application relates to the field of gas deodorization technology, specifically to an odor spraying device and deodorization equipment. Background Technology

[0002] Food waste produces odors that pollute the environment. Most existing technologies use spray deodorization processes, which introduce odors into a spray tower and use spray liquid to adsorb odor molecules in the odors, thereby removing the odors.

[0003] To further improve deodorization efficiency, several porous or pleated packing materials are often placed inside the spray tower. This allows the odor to pass through the packing material, increasing the contact area between the odor and the spray liquid. Through full gas-liquid contact, the pollutants in the odor are adsorbed, neutralized, and degraded, thus improving deodorization efficiency.

[0004] However, when the packing becomes clogged, it needs to be cleaned or replaced. However, the staff cannot know the degree of clog in real time, which means that the packing must be maintained offline regularly. The entire spray tower must be disassembled to check each packing, clean or replace it, making maintenance frequent and tedious.

[0005] Therefore, there is an urgent need for an odor spraying device and deodorization equipment to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide an odor spraying device and deodorization equipment that can detect the degree of clogging of the packing material in real time and replace the packing material online without shutting down the system when cleaning or replacement is required.

[0007] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, an odor spraying device includes: The outer casing has a purification chamber, and the outer casing is respectively provided with an air inlet, an air outlet, a material inlet and an observation port that communicate with the purification chamber; The drawer includes a drawer box and a panel. The drawer box is slidably inserted into the feed inlet. The panel is connected to the drawer box and can move between a closed position that covers the feed inlet and an open position that avoids the feed inlet. The filler is placed inside the drawer box. An observation window, connected to the housing and used to shield the observation port; A spray pipe is connected to the outer casing and has a spray nozzle facing the filler. The spray nozzle is used to spray spray liquid.

[0008] In some embodiments, the odor spraying device further includes a support frame, which is fixedly connected to the inner wall of the purification chamber and is used to support the drawer.

[0009] In some embodiments, the central axis of the air inlet is horizontally arranged, and a plurality of the packings are spaced apart along the central axis of the air inlet. The number of the feed inlet and the drawer are the same as the number of the packings and correspond one-to-one. A plurality of the packings are combined to form a purification group.

[0010] In some embodiments, at least two sets of the purification groups are arranged at intervals along the vertical direction.

[0011] In some embodiments, the number of spray pipes is the same as the number of purification groups, and they are arranged in a one-to-one correspondence.

[0012] In some embodiments, the housing includes a housing body and a flap door. The purification chamber is located inside the housing body. The air inlet, the air outlet, the material inlet, and the observation port are respectively opened on the housing body. The housing body also has a maintenance port communicating with the purification chamber. One end of the flap door is pivotally connected to the housing body. The flap door can rotate and switch between a working closed position that covers the maintenance port and a maintenance open position that avoids the maintenance port. The observation port is opened on the flap door.

[0013] In some embodiments, the housing body includes a first sidewall and a second sidewall that are corresponding to each other and spaced apart, the inlet is opened on the first sidewall, and the maintenance port is opened on the second sidewall.

[0014] In some embodiments, the odor spraying device further includes a wire mesh demister, which is fixedly connected to the inner top wall of the purification chamber.

[0015] In some embodiments, the odor spraying device further includes a swirl plate, which is fixedly connected to the wire mesh demister and is located on the side opposite to the top wall of the purification chamber.

[0016] Secondly, a deodorization device is provided, comprising a water tank and N odor spraying devices, wherein the air inlet of the (N-1)th odor spraying device is connected to the air outlet of the Nth odor spraying device, and the water outlet of the water tank is connected to the spray pipes of the N odor spraying devices respectively, and the water tank is used to store spray liquid.

[0017] The beneficial effects of this application are as follows: The odor spraying device provided in this application features a purification chamber within the outer casing, with an inlet and an outlet communicating with the chamber. Packing material is placed inside the purification chamber, and a spray pipe connected to the outer casing allows spraying of spray liquid. This enables odorous gases from food waste to flow into the purification chamber through the inlet. The packing material increases the contact area between the odorous gases and the spray liquid, achieving adsorption, neutralization, or degradation of pollutants in the odorous gases through sufficient gas-liquid contact. The deodorized odorous gases are then discharged to the outside through the outlet. An observation port communicating with the purification chamber is provided in the outer casing, with an observation window that can be shielded. This allows staff to monitor the degree of packing material blockage in real time. An inlet communicating with the purification chamber is also provided in the outer casing.

Detailed Implementation

[0024] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0025] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0026] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0027] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0028] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0029] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0030] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0031] Figure 1 A cross-sectional schematic diagram of the odor spraying device provided in this embodiment is shown. Figure 2 A front view of the odor spraying device provided in this embodiment is shown. Figure 3 A rear view of the odor spraying device provided in this embodiment is shown. Figures 1 to 3As shown, the odor spraying device provided in this embodiment includes a housing 1, a drawer 2, an observation window 3, and a spray pipe 4. The housing 1 has a purification chamber 11, and the housing 1 is provided with an air inlet 12, an air outlet 13, a feed inlet 14, and an observation port 15 that communicate with the purification chamber 11. The drawer 2 includes a drawer box and a panel 21. The drawer box is slidably inserted into the feed inlet 14, and the panel 21 is connected to the drawer box and can move between a closed position that covers the feed inlet 14 and an open position that avoids the feed inlet 14. The filler is placed in the drawer box. The observation window 3 is connected to the housing 1 and is used to cover the observation port 15. The spray pipe 4 is connected to the housing 1 and is provided with a spray nozzle 41 facing the filler. The spray nozzle 41 is used to spray the spray liquid.

[0032] The odor spraying device provided in this embodiment has a purification chamber 11 set inside the outer shell 1, with an air inlet 12 and an air outlet 13 communicating with the purification chamber 11. Packing material is placed inside the purification chamber 11, and a spray pipe 4 connected to the outer shell 1 and capable of spraying spray liquid is provided. This allows the odor generated by kitchen waste to flow into the purification chamber 11 through the air inlet 12. The packing material increases the contact area between the odor and the spray liquid, achieving adsorption, neutralization, and degradation of pollutants in the odor through sufficient gas-liquid contact. The deodorized odor can then be discharged to the outside through the air outlet 13. The shell 1 has an observation port 15 that communicates with the purification chamber 11, and an observation window 3 that can cover the observation port 15 is provided on the shell 1. The staff can know the degree of clogging of the packing in real time through the observation window 3. The drawer box is slidably inserted into the drawer box through the inlet 14 that communicates with the purification chamber 11 on the shell 1. The panel 21 is connected to the drawer box and can move between the closed position that covers the inlet 14 and the open position that avoids the inlet 14. The packing is placed in the drawer box, so that when the packing needs to be cleaned or replaced, the staff can directly pull out the drawer 2 and replace the packing online without stopping the machine.

[0033] It should be noted that the odor spraying device provided in this embodiment can not only deodorize the odor generated during the kitchen waste treatment process, but also any odorous gas can enter the purification chamber 11 through the air inlet 12 for spray deodorization, as long as it can increase the contact area with the spray liquid through the filler, and the odor molecules can be adsorbed and degraded by the spray liquid.

[0034] like Figure 1 As shown, the odor spraying device also includes a support frame 5, which is fixedly connected to the inner wall of the purification chamber 11 and used to support the drawer, thereby improving the stability of the odor spraying device and preventing the drawer 2 from being too heavy and damaging the outer shell 1, which would cause the purification chamber 11 to be directly connected to the outside and cause the spraying device to malfunction. It should be noted that the method of fixing the support frame 5 to the outer shell 1 is not limited here. The support frame 5 can be bolted, welded, or plugged into the outer shell 1, as long as it can support the drawer.

[0035] To further improve the deodorization effect of the odor spraying device. For example... Figure 1 As shown, the central axis of the air inlet 12 is horizontally positioned, and several packing materials are spaced apart along the central axis of the air inlet 12. The number of feed inlets 14 and drawers 2 is the same as the number of packing materials and corresponds one-to-one. Several packing materials are combined to form a purification group, thereby extending the odor path of the odor after it enters the purification chamber 11 through the air inlet 12. By increasing the number of packing materials or optimizing the combination of different types of packing materials, the deodorization effect of the odor spraying device can be improved. It should be noted that different types of packing materials can be placed in drawer 2 to optimize the purification capacity of the purification group.

[0036] Preferably, at least two purification groups are arranged vertically at intervals to further increase the number of packing materials or to optimize the combination of different types of packing materials to improve the deodorization effect of the odor spraying device. It should be noted that the number of purification groups is not limited here; it can be two, three, four, or even more. Those skilled in the art can reasonably set the number of purification groups according to the actual needs of the odor spraying device. The packing materials of different purification groups can also be of different types, so that multiple types of purification groups work together to improve the deodorization effect of the odor spraying device.

[0037] Continue as Figure 1 As shown, the number of support frames 5 is the same as the number of drawers 2 and they correspond one-to-one. Several support frames 5 are spliced ​​together to form a support body, thereby further improving the sturdiness of the odor spraying device. At the same time, the support body can be pre-assembled according to the actual needs of the amount of filler in the odor spraying device, so that the support body can better support the outer shell 1. The modular design reduces the installation difficulty of the support body. It should be noted that the splicing method between the support frame 5 and its adjacent support frame 5 is not limited here. It can be plug-in, welding or bolt connection, as long as several support frames 5 can be spliced ​​together to form a support body.

[0038] Preferably, the number of spray pipes 4 is the same as that of the purification group and they are set in a one-to-one correspondence, so that the spray liquid sprayed by the spray pipes 4 can be sprayed evenly and fully onto the packing material, increasing the contact area between the spray liquid and the odor, and preventing the packing material from being reduced by uneven spraying of the spray liquid, thus reducing the spray purification effect of the odor spraying device.

[0039] Furthermore, the number of spray nozzles 41 in a single spray pipe 4 is the same as the number of fillers in its corresponding purification group, and they are set in a one-to-one correspondence to ensure that the fillers in a single purification group can be sprayed with spray liquid evenly.

[0040] In some embodiments, an atomizing nozzle is fixedly provided at the spray port 41, so that the spray port 41 sprays out atomized spray liquid, and the filler is evenly sprayed with spray liquid.

[0041] When using an odor spraying device to deodorize odorous gases, stains from the odorous gases often accumulate inside the purification chamber 11, requiring regular cleaning. To solve this technical problem, such as... Figure 3 Combination Figures 1 to 2 As shown, the outer casing 1 includes an outer casing body 16 and a flap door 17. The purification chamber 11 is located inside the outer casing body 16. The air inlet 12, air outlet 13, feed inlet 14, and observation port 15 are all opened on the outer casing body 16. The outer casing body 16 is also provided with a maintenance port 18 that communicates with the purification chamber 11. One end of the flap door 17 is pivotally connected to the outer casing body 16. The flap door 17 can rotate and switch between a working closed position that covers the maintenance port 18 and a maintenance open position that avoids the maintenance port 18. The observation port 15 is opened on the flap door 17, so that when it is necessary to clean the purification chamber 11, the flap door 17 can be rotated to open the flap door 17, and the staff can then clean the accumulated dirt in the purification chamber 11. Specifically, the outer shell 16 includes a first sidewall 161 and a second sidewall 162 that are corresponding to each other and spaced apart. The feed inlet 14 is opened on the first sidewall 161 and the maintenance port 18 is opened on the second sidewall 162. Thus, opening the trapdoor 17 and pulling out the drawer 2 do not affect each other. That is, replacing the filler and cleaning the purification chamber 11 can be done at the same time, improving the maintenance efficiency of the odor spraying device.

[0042] Preferably, the number of maintenance ports 18 and the number of feed ports 14 are the same, and they are arranged directly opposite each other. This allows the valve door 17 at the corresponding position to be opened only when it is found that there is too much dirt in a local area of ​​the purification chamber 11, so as to clean the local dirt. This allows the purification chamber 11 to be cleaned online without stopping the machine, thereby further improving the maintenance efficiency of the odor spraying device.

[0043] like Figure 1 As shown, the odor spraying device also includes a wire mesh demister 6, which is fixedly connected to the inner top wall of the purification chamber 11, thereby intercepting the spray liquid carried in the odor, reducing the spray liquid carried out after odor deodorization, saving spraying agents, and improving the spray deodorization effect of the odor spraying device.

[0044] In some embodiments, the odor spraying device further includes a swirl plate 7, which is fixedly connected to the wire mesh demister 6. The swirl plate 7 is located on the side away from the inner top wall of the purification chamber 11, thereby rotating the odor to increase the contact area between the odor and the wire mesh demister 6, so that the wire mesh demister 6 can better intercept the spray liquid entrained in the odor.

[0045] This embodiment also provides a deodorization device, including a water tank and N odor spray devices. The air inlet 12 of the (N-1)th odor spray device is connected to the air outlet 13 of the Nth odor spray device. The water outlet of the water tank is connected to the spray pipes 4 of the N odor spray devices respectively. The water tank is used to store spray liquid, thereby combining the multi-stage odor spray devices to efficiently remove odors from the odor.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
