[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , the present invention provides a low-carbon biological deodorization system, including a biological deodorization main device, a pump valve system and a control system;

[0036] The biological deodorization main device comprises a pre-washing section 1, a biological section 2 and a humidity response area 3. The pre-washing section 1 and the biological section 2 are respectively provided with a water storage layer, an air distribution layer, a filler layer and a spray layer from bottom to top;

[0037] The pump-valve system consists of an induced draft fan, a working pump 4, a standby pump 5, a switching valve group and pipelines.

[0038] In this embodiment, a humidity response zone is set according to the humidification demand of the biological section, the humidity sensing sensitivity is improved, the humidification demand can be fed back in time, and energy loss and water resource loss can be effectively avoided, thereby achieving the effect of energy saving and emission reduction; compared with the conventional biological deodorization system, the humidification water pump of the biological section is eliminated, and the working pump and spare pump of the pre-washing section are effectively utilized, which reduces the cost and the failure points, thereby reducing the operation and maintenance energy consumption.

[0039] In one embodiment, see Figure 1 The water inlet of the working pump 4 is connected to the pre-washing section water storage layer and the biological section water storage layer through the switching valve 1 61 and the switching valve 2 62, respectively, and the water outlet of the working pump 4 is connected to the pre-washing section spray layer and the biological section spray layer through the switching valve 3 63 and the switching valve 4 64, respectively;

[0040] The water inlet of the standby pump 5 is connected to the pre-wash section water storage layer and the biological section water storage layer through the switching valve five 65 and the switching valve six 66 respectively, and the water outlet of the standby pump 5 is connected to the pre-wash section spray layer and the biological section spray layer through the switching valve seven 67 and the switching valve eight 68 respectively.

[0041] This embodiment is configured in this way to effectively utilize the working pump and standby pump of the pre-wash section, reduce costs, reduce failure points, and thus reduce operation and maintenance energy consumption.

[0042] In one embodiment, see Figure 1 and Figure 2 The humidity response area 3 is a cross-shaped structure 7, the center point of the cross-shaped structure 7 is located at the center of the biological segment filler layer, and the end extends to the boundary of the biological segment filler layer. A movable covering net 8 is provided on the front and rear sides of the cross-shaped structure 7.

[0043] This embodiment is configured such that the cross-shaped structure 7 can be protected by the setting of the covering net 8, and a certain distance can be maintained between the cross-shaped structure 7 and the surrounding biological segment filler layer when the cross-shaped structure 7 performs humidification operation, so that the humidification water can reach the corresponding area quickly and unobstructed, thereby ensuring the timely response of the humidification effect.

[0044] Specifically, the covering net 8 may be made of an air-permeable and water-permeable material, and a mechanism for driving the covering net 8 to move may be disposed outside the humidity response area 3 .

[0045] In one embodiment, see Figure 3 The cross-shaped structure 7 includes a cross bracket 71, which can be rotatably arranged around the center, and sensing points 72 are evenly arranged on each branch of the cross bracket 71, and the sensing points 72 are symmetrically arranged along the front and rear sides of the cross bracket 71. A humidification structure 73 connected to each sensing point 72 is provided in the cross bracket 71. When the sensing point 72 detects that the humidity value is lower than the set value, the humidification structure 73 is controlled to perform fixed-point humidification on the alarm sensing point 72.

[0046] This embodiment is configured such that when the humidity data at a local position in the humidity response area 3 drops to a set value, the sensing point 72 here promptly feeds back the detection data, controls the humidification structure 73 there to work independently, and performs fixed-point humidification on the area where abnormal humidity data appears, which can not only quickly and accurately perform humidification operations at the location, but also save resources and avoid waste.

[0047] At the same time, the cross bracket 71 can be rotatably arranged around the center, and is used to control the rotation of the cross bracket 71 when an alarm is triggered at multiple sensing points 72 or when the humidification operation is not performed regularly, and the biological segment filler layer is uniformly humidified through the humidification structure 73 arranged thereon, which can effectively avoid detection blind spots and improve humidification efficiency.

[0048] Specifically, the sensing point 72 may be a sensor or an electronic component for detection.

[0049] Specifically, the rotation of the cross bracket 71 can be driven by water flow, that is, the center of the cross bracket 71 is a cavity with blades, and water is injected into the cavity through an external water pipe to drive the cross bracket 71 to rotate. The injected water flow can flow to the humidification structure 73 synchronously, and the use effect is good.

[0050] In one embodiment, see Figure 3 The humidifying structure 73 includes a water outlet nozzle 731 with a valve, the water outlet of the water outlet nozzle 731 is arranged toward the cross bracket 71, a water dispersion plate 732 is arranged on the water outlet path of the water outlet, the water dispersion plate 732 is fixedly inserted on the rotating shaft 736, the top of the rotating shaft 736 is connected to the rotating structure, the rotating structure is directly opposite to the water diversion hole opened on the cross bracket 71, the water dispersion plate 732 is an umbrella-shaped structure, and the water dispersion plate 732 has a water containing cavity 733 in the center, and the water containing cavity 733 is surrounded by water guide channels 734 that are connected to the water containing cavity and are evenly distributed along the inner surface of the water dispersion plate 732;

[0051] See also Figure 4 The water guide channel 734 includes a first channel 7341 and a second channel 7342 that are spaced apart from each other on the inner surface of the water dispersion plate 732 . The first channel 7341 is radially arranged along the inner surface of the water dispersion plate 732 and extends to the outer edge. The second channel 7342 has at least one water outlet hole parallel to the water outlet nozzle 731 .

[0052] The present embodiment is arranged in this way. Since each sensing point 72 corresponds to an area, by arranging the water outlet of the water outlet nozzle 731 toward the water dispersion plate 732, the ejected water flow can have a larger coverage area after dispersion, and at the same time, the humidification accuracy can be better controlled to avoid the problem of overflow of the humidification value caused by excessive concentration of the water flow; specifically, the water flow ejected by the water outlet nozzle 731 is reversely ejected into the water containing cavity 733 of the water dispersion plate 732, driving the water dispersion plate 732 to rotate around the rotating shaft 736, and at the same time, the water flow enters the water guide channel 734, a part of the water flow enters the first channel 7341, and is dispersed outward along the outer edge of the water dispersion plate 732, and the other part of the water flow enters the second channel 7342, and is dispersed outward along the direction parallel to the water outlet nozzle 731. At this time, not only can the humidification area be effectively humidified without dead angles, but also the humidification uniformity can be maintained in cooperation with the rotating water dispersion plate 732, ensuring that the area can be humidified at the fastest and best speed.

[0053] Preferably, at least two water storage chambers with the same space are provided in the water outlet nozzle 731, and the water storage chambers are connected by a solenoid valve. The solenoid valve and the sensing point 72 are in the same detection circuit. When the humidification water in one water storage chamber is released, the sensing point 72 promptly feeds back the real-time humidification data. If the set value is not reached, the solenoid valve opens and continues to release the humidification water in the next water storage chamber until the humidification data reaches the set value and the humidification operation is stopped. In this way, the humidification accuracy can be controlled more accurately to avoid the problem of excessive humidification.

[0054] In one embodiment, a protective member 735 is disposed on the water outlet nozzle 731 , and the diameter of the end of the protective member 735 is smaller than the diameter of the water dispersion tray 732 .

[0055] This embodiment is configured in this way to protect the water outlet of the water outlet nozzle 731 from being blocked, thereby reducing the trouble of later maintenance. For details, please refer to Figure 5 The protective member 735 is a two-piece structure. The two-piece structure forms a circular piece arranged at the water outlet of the water outlet nozzle 731, and the two-piece structure is independently provided with a rotating structure. The rotating structure includes a rotating shaft 736 and a torsion spring to ensure that when the water outlet nozzle 731 is not discharging water, the protective member 735 is in a closed state to avoid the problem of clogging the water outlet of the water outlet nozzle 731.

[0056] In one embodiment, see Figure 3 This embodiment provides another structure of the protective member 735, which includes a movable block 7351 connected to the water outlet nozzle 731, the movable block 7351 is movably sleeved on the rotating shaft 736, the rotating shaft 736 is sleeved with a spring 7352 connected to the movable block 7351, and support rods 7353 are provided around the movable block 7351. Adjacent support rods 7353 are connected by isolation cloth, and the support rods 7353 are connected to the fixed block 7355 fixed on the rotating shaft 736 through a folding rod 7354.

[0057] The present embodiment is configured such that the movable block 7351 can be controlled to move by a linear drive element, and the opening angle of the support rod 7353 can be controlled by adjusting the distance between the movable block 7351 and the fixed block 7355, so that when the water outlet of the water outlet nozzle 731 needs to be protected, the support rod 7353 can be driven to open so that the isolation cloth covers the water outlet, and when the water outlet path and the water outlet angle need to be adjusted, the isolation cloth can be controlled to expand and contract by controlling the support rod 7353. At this time, it can be used alternately with the water guide channel 734 as needed to achieve control of the coverage range of different areas and the water outlet angle.

[0058] Specifically, the protective member 735 is disposed between the water dispersion tray 732 and the water outlet nozzle 731 .

[0059] In one embodiment, see Figure 6 The water outlet of the biological section spray layer is provided with an adapter 9, and a control valve is provided at the adapter 9. The adapter 9 has double water outlets, one of which is directly facing the top of the biological section spray layer, and the other water outlet is connected to the cross-shaped structure 7 through a drainage pipe.

[0060] This embodiment is configured in this way. According to the actual situation, it is possible to choose to direct the water flow to the top of the biological section spray layer for large-area humidification operation, or to direct the water flow to the cross-shaped structure 7 for fixed-point humidification. The selection range is wider, ensuring that the humidification operation can be carried out efficiently.

[0061] In one embodiment, see Figure 6 Water distribution pipes 10 are evenly arranged on the periphery of the biological section 2, and the outlet ends of the water distribution pipes 10 are arranged facing the outside of the biological section 2.

[0062] This embodiment is configured so that the outer layer of the biological stage filler layer can be humidified when needed through the water balancing pipe 10, thereby improving the comprehensiveness of the humidification operation and further improving the humidification effect.

[0063] The present invention also provides a low-carbon biological deodorization method, which uses the low-carbon biological deodorization system as described above and specifically includes the following steps:

[0064] The system automatically runs when powered on, opens the switching valve 1 61 and the switching valve 3 63, then starts the working pump 4, and finally starts the induced draft fan;

[0065] When the working pump 4 continues to run and reaches the pump change cycle or the working pump 4 or the switching valve 1 61 or the switching valve 3 63 fails, the pump change command is executed, firstly the switching valve 5 65 and the switching valve 7 67 are opened, then the standby pump 5 is opened, then the working pump 4 is closed, and finally the switching valve 1 61 and the switching valve 3 63 are closed;

[0066] When the humidity in the humidity response area 3 is lower than the humidity setting value, the humidification command is executed. If the working pump 4 is in the on state, the switching valve 66 and the switching valve 8 68 are opened, and then the standby pump 5 is turned on. When the humidity in the humidity response area 3 is higher than the setting value, the standby pump 5 is turned off, and then the switching valve 66 and the switching valve 8 68 are closed; if the standby pump 5 is in the on state, the switching valve 2 62 and the switching valve 4 64 are opened, and then the working pump 4 is turned on. When the humidity in the humidity response area 3 is higher than the setting value, the working pump 4 is turned off, and then the switching valve 2 62 and the switching valve 4 64 are closed;

[0067] When the humidity in the humidity response area 3 is lower than the humidity setting value, the working pump 4 and the standby pump 5 are triggered in an interchangeable cycle at the same time, or when a pump failure occurs, the pump change command is executed first, and then the humidification command is executed;

[0068] When the pump valve system fails, resulting in the inability to execute the pump change command, or the induced draft fan fails, the system will sound an alarm and stop running.

[0069] This embodiment eliminates the humidification water pump of the biological section and effectively utilizes the working pump 4 and the standby pump 5 of the pre-wash section, thereby reducing costs and failure points, thereby reducing operation and maintenance energy consumption.

[0070] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0071] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.
