Description

Technical Field

[0001] The utility model relates to the technical field of biological deodorization, in particular to a multi-threaded high-efficiency biological deodorizer. Background Art

[0002] A bio-deodorizer is an environmentally friendly device that uses the metabolic activity of microorganisms to remove odors. Its core principle is biodegradation. Within the bio-deodorizer, a large number of microorganisms exist, which use odorous substances as their nutrient source. When odorous gases pass through the bio-deodorizer, the microorganisms, under suitable environmental conditions (such as temperature, humidity, and pH), metabolize the odorous substances into harmless substances such as carbon dioxide, water, and inorganic salts, thereby achieving the purpose of deodorization.

[0003] However, the current biological deodorizer has a relatively simple treatment function. When faced with air with more complex "odor" sources, it is a bit powerless. Its treatment capacity needs to be further improved and optimized. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-threaded working and efficient biological deodorizer.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A multi-threaded high-efficiency biological deodorizer, comprising a main body support mechanism and a multi-threaded deodorizing mechanism arranged in the main body support mechanism;

[0011] Note: The blank circulation holes make it easy to bypass the multi-threaded support beam and enter the biological deodorization unit on the next multi-threaded support beam for deodorization.

[0012] Preferably, circulation opening and closing mechanisms are provided at the top of the multi-threaded support beam at the positions of the blank circulation holes and the deodorization circulation holes. The circulation opening and closing mechanism includes a circulation opening and closing fixing plate fixed at the top of the multi-threaded support beam at the positions of the blank circulation holes and the deodorization circulation holes.

The camshaft has a sliding drive mating groove, and a sliding drive short column is fixed at the top of the circulation opening and closing mating plate. The sliding drive short column is slidably fitted in the sliding drive mating groove.

[0015] Note: The circulation opening and closing mechanism can specifically control whether the two ends of each biological deodorization unit are in circulation, specifically remove the "odor" source, and avoid a substantial increase in cost caused by redundant use of biological deodorization units.

[0017] The deodorization circulation buffer spaces between two adjacent deodorization circulation support shells at the same horizontal position are connected through a plurality of adjacent cooperative circulation holes;

[0018] The cooperative opening and closing mechanism includes a pair of cooperative opening and closing restraint chutes with opposite openings fixed on the inner side wall of the deodorization circulation support shell at the positions of the adjacent cooperative circulation holes. A cooperative opening and closing control plate is slidably connected between each pair of cooperative opening and closing restraint chutes. The cooperative opening and closing control plate has a plurality of cooperative opening and closing through holes;

[0019] The cooperative opening and closing control plate is driven to move by a cooperative opening and closing drive rod fixed on the inner side wall of the deodorization circulation support shell.

[0020] Note: The cooperative opening and closing mechanism is used to parallel the biological deodorization units in adjacent deodorization circulation support shells to improve the odor treatment ability.

[0051] Embodiment 2:

[0052] Based on Embodiment 1, as Figure 1 shown, a deodorization flow buffer space 120 is formed between two adjacent multi-threaded support beams 13 along the vertical direction inside the deodorization flow support shell 12. A cooperative opening and closing mechanism 32 is provided on the side wall of the deodorization flow support shell 12 in the deodorization flow buffer space 120;

[0053] As Figure 6 shown, the deodorization flow buffer spaces 120 of two adjacent deodorization flow support shells 12 at the same horizontal position are connected by a plurality of adjacent cooperative flow holes 320;

[0054] As Figure 5 、 Figure 6 shown, the cooperative opening and closing mechanism 32 includes cooperative opening and closing constraint chutes 321 with opposite openings fixed on the inner side wall of the deodorization flow support shell 12 near the adjacent cooperative flow holes 320. A cooperative opening and closing control plate 322 is slidably connected between each pair of cooperative opening and closing constraint chutes 321. The cooperative opening and closing control plate 322 has a plurality of cooperative opening and closing through holes 3220;

[0055] The cooperative opening and closing control plate 322 is a plate-shaped structure. By controlling the movement of the cooperative opening and closing control plate 322, the connection or disconnection between each cooperative opening and closing through hole 3220 and the adjacent cooperative flow hole 320 can be controlled;

[0056] The cooperative opening and closing control plate 322 is driven to move by a cooperative opening and closing drive rod 323 fixed on the inner side wall of the deodorization flow support shell 12. The cooperative opening and closing drive rod 323 is an electric control telescopic rod. The outer rod end of the cooperative opening and closing drive rod 323 is fixedly connected to the inner side wall of the deodorization flow support shell 12, and the inner rod of the cooperative opening and closing drive rod 323 is fixedly connected to the cooperative opening and closing control plate 322.

[0057] It should be noted that the biological attachment filler 210, the cooperative opening and closing drive rod 323, and the end filter 103 used in this application all adopt existing technologies and are not specifically limited here. Those skilled in the art can select them according to needs as long as the technical solutions of this application can be achieved.

[0058] In the actual application process of the present utility model, the air to be deodorized enters the initial input space 101 through each initial input pipe 111. The air to be deodorized flows from top to bottom in each deodorization flow support shell 12, and the biological deodorization units 21 are used to perform biological deodorization work on the air to be deodorized;

[0059] The types of multiple biological deodorization units 21 on different multi-threaded support beams 13 within the same deodorization flow-through support shell 12 are different, which means that multiple types of microorganisms targeting different odor sources are attached to the biological attachment filler 210;

[0060] The multiple deodorization flow-through support shells 12 within the main body support outer shell 11 are sequentially designated as C1, C2, C3, C4, C5 from left to right, and each multi-threaded support beam 13 within the same deodorization flow-through support shell 12 is sequentially numbered as L1, L2, L3, L4 from top to bottom. The biological deodorization unit 21 installed on the multi-threaded support beam 13 numbered L1 is for removing hydrogen sulfide odor, and the microorganism attached to the biological attachment filler 210 in the corresponding biological deodorization unit 21 is "Thiobacillus thiooxidans";

[0061] The biological deodorization unit 21 installed on the multi-threaded support beam 13 numbered L2 is for removing ammonia odor, and the microorganism attached to the biological attachment filler 210 in the corresponding biological deodorization unit 21 is "Nitrosomonas";

[0062] The biological deodorization unit 21 installed on the multi-threaded support beam 13 numbered L3 is for removing volatile organic compound (VOCs) odor, and the microorganism attached to the biological attachment filler 210 in the corresponding biological deodorization unit 21 is "white rot fungus";

[0063] The biological deodorization unit 21 installed on the multi-threaded support beam 13 numbered L4 is for removing fatty acid rancidity odor, and the microorganism attached to the biological attachment filler 210 in the corresponding biological deodorization unit 21 is "Bacillus";

[0064] The above "Thiobacillus thiooxidans", "Nitrosomonas", "white rot fungus", and "Bacillus" are all strains of the prior art and can be purchased and used as needed.

[0065] Multiple gas sensors for detecting the types of "odors" are fixed on the input uniform flow plate 121, and the gas sensors are photoionization sensors;

[0066] By analyzing the input gas, the "odor" source is then targeted for removal, avoiding a substantial increase in cost caused by redundant use of the biological deodorization unit 21;

[0067] For example, only the smell of hydrogen sulfide and the smell of rancid fatty acids are detected in the input gas. The flow opening and closing mechanism 31 is used to control whether the two ends of each biological deodorization unit 21 are in communication. At this time, each biological deodorization unit 21 in the deodorization flow support shell 12 numbered C1 is used for deodorization treatment. It is only necessary to control the biological deodorization units 21 installed on the multi-threaded support beam 13 numbered L1 and the biological deodorization units 21 installed on the multi-threaded support beam 13 numbered L4 to perform the communication work;

[0068] The working principle of the flow opening and closing mechanism 31 is as follows:

[0069] The camshaft 135 is driven to rotate by a servo motor fixed on the camshaft support 314. Using the constraint effect between the sliding drive mating groove 3150 and the sliding drive short column 316, the flow opening and closing mating plate 313 is driven to move along the constraint chute 312, so that the flow fixing hole 3110 and the flow mating hole 3130 are connected in the vertical direction, so that the upper and lower ends of a single biological deodorization unit 21 are in a communicating state, so that the air flow can flow through the biological deodorization unit 21 from top to bottom, and the air flow is in full contact with the microorganisms attached to the biological attachment filler 210, and the deodorization work is realized by the decomposition action of the microorganisms;

[0070] It is set that in the flow opening and closing mechanism 31, if the flow fixing hole 3110 and the flow mating hole 3130 are connected, the flow opening and closing mechanism 31 is in the open state. If the flow fixing hole 3110 and the flow mating hole 3130 are misaligned and isolated from each other, the flow opening and closing mechanism 31 is in the closed state;

[0071] When the flow opening and closing mechanism 31 at the deodorization flow hole 132 on the same multi-threaded support beam 13 is in the open state, the flow opening and closing mechanism 31 at the blank flow hole 131 is in the closed state;

[0072] At this time, the flow opening and closing mechanism 31 at the deodorization flow hole 132 on the multi-threaded support beam 13 numbered L1 is in the open state, and the flow opening and closing mechanism 31 at the blank flow hole 131 is in the closed state;

[0073] The flow opening and closing mechanism 31 at the deodorization flow hole 132 on the multi-threaded support beam 13 numbered L4 is in the open state, and the flow opening and closing mechanism 31 at the blank flow hole 131 is in the closed state;

[0074] The flow opening and closing mechanism 31 at the deodorization flow hole 132 on the multi-threaded support beam 13 numbered L2 is in the closed state, and the flow opening and closing mechanism 31 at the blank flow hole 131 is in the open state;

[0075] The flow opening and closing mechanism 31 at the deodorizing flow hole 132 of the multi-threaded support beam 13 numbered L3 is in the closed state, while the flow opening and closing mechanism 31 at the blank flow hole 131 is in the open state;

[0076] For the multi-threaded support beams 13 numbered L2 and L3, it is only necessary to allow the air flow to pass through the blank flow hole 131;

[0077] If the concentration of hydrogen sulfide odor is relatively high at this time, the cooperative opening and closing mechanism 32 can be used to parallel the biological deodorization units 21 for removing hydrogen sulfide odor in the adjacent deodorizing flow support shells 12 to improve the treatment capacity for hydrogen sulfide odor;

[0078] The specific working process of the cooperative opening and closing mechanism 32 is as follows:

[0079] First, it is set that when the cooperative opening and closing through hole 3220 is connected to the adjacent cooperative flow hole 320, that is, the cooperative opening and closing mechanism 32 is in the open state, and when the cooperative opening and closing through hole 3220 is misaligned and isolated from the adjacent cooperative flow hole 320, that is, the cooperative opening and closing mechanism 32 is in the closed state;

[0080] The cooperative opening and closing control board 322 is driven by the cooperative opening and closing drive rod 323 to move along the cooperative opening and closing constraint chute 321, thereby controlling the connection or misalignment and isolation between the cooperative opening and closing through hole 3220 and the adjacent cooperative flow hole 320;

[0081] In the deodorizing flow buffer spaces 120 on the upper and lower adjacent sides of the multi-threaded support beam 13 numbered L1 in the deodorizing flow support shell 12 numbered C1, the cooperative opening and closing mechanism 32 on the side adjacent to the deodorizing flow support shell 12 numbered C2 is in the open state. At this time, the biological deodorization units 21 on the multi-threaded support beam 13 numbered L1 in the deodorizing flow support shell 12 numbered C1 and the biological deodorization units 21 on the multi-threaded support beam 13 numbered L1 in the deodorizing flow support shell 12 numbered C2 are in a parallel state to improve the treatment capacity for hydrogen sulfide odor;

[0082] The core of biological deodorization is the decomposition of odor substances by microorganisms. In the multi-threaded deodorizer, there are various types of microbial communities, which each decompose different odor substances. These microbial communities are like multiple work teams, simultaneously handling different tasks. Through the synergistic effect of these multi-microbial communities, the efficient treatment of complex odors is achieved;

[0083] The deodorized air finally enters the overall output space 102 through the output through hole 1220, and finally the air is filtered by multiple end filters 103. The end filters 103 are activated carbon filters, and then the air can be discharged from the overall output pipe 112.
