Description

Technical Field

[0001] This utility model relates to the field of gas deodorization technology, and in particular to a circulating deodorization system. Background Technology

[0002] Odor pollution has become a major global public health concern. With accelerated urbanization, the production of organic waste such as food waste and livestock feed is rapidly increasing, exacerbating the problem of odor emissions. The main components of odorous gases include hydrogen sulfide, ammonia, thiols, and sulfides, which are characterized by high volatility, low odor thresholds, and high toxicity. Once released into the air, they can cause anything from unpleasant odors to serious health hazards and environmental damage.

[0003] Currently, technologies for treating odorous gases mainly include adsorption, absorption, low-temperature plasma, and biofiltration. Adsorption technology uses adsorbent materials such as activated carbon to capture odor molecules, suitable for treating low-concentration gases, but requires frequent material replacement and has limited adsorption capacity. Absorption technology utilizes liquid absorbents to chemically react with odorous gases, suitable for treating medium- to high-concentration odorous gases, but requires large absorbent consumption and has high operating costs. Low-temperature plasma relies on high-energy electrons to break down odorous gas molecules, offering high efficiency, but the equipment has high energy consumption and limited applicability. Biological treatment technology uses microorganisms to degrade odorous substances, offering strong environmental friendliness and low operating costs, but has long start-up times and is greatly limited by environmental conditions.

[0004] In addition, although the above technologies have alleviated the harm of malodorous gases to some extent, in practical applications, some technologies only focus on removing malodorous substances without considering the recovery of usable resources. Furthermore, they require a large amount of fresh water as an absorption medium during use, which increases the pressure on water resources.

[0005] Therefore, there is an urgent need for a highly efficient integrated technology that can combine deodorization, resource recycling, and water conservation to achieve the sustainable development goal of odor control. Summary of the Invention

[0006] Therefore, this utility model provides a circulating deodorization system that achieves efficient recycling of water resources through a circulating storage tank and a wastewater purification pond, thereby reducing water consumption and lowering the environmental burden.

[0012] A barrier, located on the other side of the spray device, includes a breathable layer that can intercept some of the deodorizing solution droplets.

[0013] An odor dissolution tank is located below the barrier body and is used to collect the tail liquid flowing down from the barrier body;

[0014] The wastewater purification tank is connected to the return end of the circulating storage tank and the odor dissolving tank, respectively.

[0015] In one embodiment of this utility model, the air-expelling device includes a fan.

[0025] This utility model discloses a circulating deodorization system that, through a spray device and multiple layers of permeable layers (barriers), ensures full contact between malodorous gases and the deodorizing solution, significantly increasing the gas-liquid interface area and greatly improving deodorization efficiency.

The system achieves efficient water resource recycling through a circulating storage tank and a wastewater purification tank, reducing water consumption and environmental burden. The tailings liquid can be reused after treatment in an odor dissolving tank and wastewater purification tank, reducing wastewater discharge and minimizing environmental impact.

For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0043] Reference Figure 1 As shown, the present invention provides a circulating deodorization system, comprising:

[0044] A circulating storage tank 1 is used to provide a deodorizing solution (an aqueous solution containing a deodorizing agent). The circulating storage tank 1 includes an outlet end and a return end. The circulating storage tank 1 provides the deodorizing solution required for spraying and reduces water waste through recycling.

[0045] The spray deodorization device includes:

[0046] The spraying device 2 is connected to the liquid outlet of the circulating storage tank 1 and is used to atomize and spray the deodorizing solution.

[0047] The ventilation device 3 is located on one side of the spray device 2 and is used to introduce (indoor) malodorous gas into the spray device 2 through negative pressure so that it can mix and come into contact with the deodorizing solution; the spray head of the spray device 2 evenly sprays the aqueous solution containing the deodorizing agent to form an environment in which gas and liquid are fully in contact, thereby absorbing the malodorous components.

[0048] The blocking body 4 is disposed on the other side of the spray device 2 and includes a breathable layer 41. The breathable layer 41 can intercept some of the droplets of the deodorizing solution. The breathable layer 41 further expands the contact area between the deodorizing solution and the malodorous gas, and improves the absorption efficiency of the malodorous components.

[0049] Odor dissolution tank 5 is located below the barrier 4 and is used to collect the tail liquid (a solution containing malodorous substances) flowing down from the barrier 4. The odor dissolution tank 5 collects and temporarily stores the tail liquid, providing processing space for subsequent biological transformation and purification. The malodorous substances in the tail liquid can be transformed into usable resources here through the action of microorganisms.

[0050] Wastewater purification tank 6 is connected to the return end of the circulating storage tank 1 and the odor dissolving tank 5. Wastewater purification tank 6 can remove impurities and return the water to the clean water storage tank, while separating and recovering microorganisms and some sediments for resource utilization.

[0051] In one embodiment, the air intake device 3 includes a fan.

[0052] Specifically, refer to Figure 3 As shown, the barrier 4 includes multiple layers of breathable layers 41 arranged side-by-side at intervals. Exemplarily, the breathable layers 41 have 2-4 layers. Preferably, there are 3 layers, each composed of a steel pipe support and gauze, forming a screen-like structure. These layers are evenly distributed within the spray device 2. The multi-layered screen structure significantly increases the coverage area of ​​the aqueous solution and the damping effect of the gas channel, prolonging the gas-liquid contact time. The screen surface captures droplets formed by the spray, further dissolving odorous substances in the gas into the liquid, thus improving deodorization efficiency. The collected liquid flows along the screen structure to the lower water tank for subsequent recycling and treatment.

[0053] Understandably, when the aqueous solution is sprayed onto the surface of the permeable layer 41, it adheres to the surface, forming a uniformly distributed liquid film or droplets. The multiple layers of permeable layers 41 provide staggered paths for gas passage. As the airflow passes through each layer of permeable layer 41, it comes into contact with the liquid film or droplets attached to the permeable layer 41, which significantly increases the contact area between the odorous gas and the aqueous solution.

[0054] The multi-layered breathable layer 41 design allows gas to pass through the device repeatedly, reducing the airflow speed as it passes through the screen due to the obstruction of the breathable layer 41. This increases the contact time of the airflow, ensuring that the odor molecules in the gas fully interact with the aqueous solution, thereby improving the deodorization efficiency.

[0055] In one embodiment, the breathable layer 41 is a mesh. Optionally, the mesh may be made of cotton yarn, stainless steel, fiber mesh, galvanized steel yarn, or a Teflon-coated metal mesh, which has strong corrosion resistance.

[0056] Reference Figure 2 As shown, in one embodiment, a frame 42 (steel pipe support) is further included for mounting multiple layers of the permeable layer 41. An arc-shaped baffle 43 is disposed after the last layer of the permeable layer 41. The arc-shaped baffle 43 is used to block and guide droplets that pass through multiple layers of the arc-shaped baffle 43 into the odor dissolution tank 5. The arc-shaped baffle 43 effectively collects the tail liquid, prevents solution splashing, and guides it into the water tank below, achieving efficient liquid recovery.

[0057] In one embodiment, the spraying device 2 includes a spray chamber and a plurality of spray heads disposed within the spray chamber, the spraying direction of the plurality of spray heads being vertically downward. It should be noted that the baffle 4 can be directly installed in the spray chamber, the arc-shaped baffle 43 and the fan are installed at the openings on both sides of the spray chamber, and there is a drainage groove at the bottom of the spray chamber.

[0058] In one embodiment, a first water pump 7 is provided between the liquid outlet of the circulating storage tank 1 and the spray device 2, and a second water pump 8 is provided between the wastewater purification tank 6 and the circulating storage tank 1.

[0059] In one embodiment, the bottom of the odor dissolving tank 5 is designed with a settling area to allow particulate impurities, sediments, and other substances to settle. Specific microorganisms can be added to the odor dissolving tank 5 as needed to initially decompose the malodorous components in the liquid, converting them into harmless or recyclable substances. The wastewater purification tank 6 removes suspended impurities and fine particles from the tailings through physical filtration, reducing water turbidity. Microorganisms are introduced to degrade residual malodorous components and organic pollutants in the tailings, converting them into harmless substances. For some pollutants that are difficult to biodegrade, chemical agents can be added for further neutralization or decomposition to ensure that the treatment meets standards.

[0060] During operation, a negative pressure is generated by a fan, drawing air containing odorous gases into the spray deodorization device. The spray device 2 obtains the deodorizing solution from the outlet of the circulating storage tank 1, atomizes it, and sprays it evenly into the spray chamber, forming fine droplets or a liquid film. As the airflow passes through the spray area, it comes into contact with the deodorizing solution droplets, and pollutants in the odorous gases (such as hydrogen sulfide and ammonia) are absorbed into the liquid phase. The sprayed airflow passes through multiple permeable layers 41, where the liquid film further contacts the gas, absorbing any remaining odorous components and enhancing the deodorization effect. The liquid intercepted by the baffle 4 flows downwards by gravity or is guided by the arc-shaped baffle 43, ultimately flowing into the odor dissolution tank 5. After entering the odor dissolution tank 5, the tail liquid undergoes preliminary physical sedimentation, separating some impurities or particulate matter. The tail liquid discharged from the odor dissolution tank 5 enters the wastewater purification tank 6 for purification; the purified water meets the standards for using the spray solution. The water treated in the purification tank is returned to the circulating storage tank 1, and an appropriate amount of deodorizing reagent is added as needed to form a new deodorizing solution. The solution in the circulating storage tank 1 then participates in deodorization again through the spray device 2, completing one cycle.

[0061] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
