Description

Technical Field

[0001] This utility model belongs to the field of biological deodorization technology, and specifically refers to a humidification device for biological deodorization equipment. Background Technology

[0002] Biological odor control equipment typically refers to devices that utilize the biological metabolism of microorganisms to remove odors and harmful gases from the air. These devices are widely used in sewage treatment plants, waste disposal stations, farms, and industrial production facilities to reduce the impact of odors on the environment and human health. The packing layer is a core component of biological odor control equipment, providing the necessary attachment and growth environment for microorganisms, enabling them to efficiently degrade airborne pollutants. The materials used for the packing layer can be diverse, including organic materials such as sawdust, bark, and coconut shells, as well as inorganic materials such as plastic packing, ceramic packing, and volcanic rock. These materials usually have a large specific surface area to increase the attachment area for microorganisms, while ensuring good ventilation and appropriate humidity to maintain microbial activity.

[0003] In existing technologies, because there is a certain distance between the gas distribution pipe and the packing layer, the gas is sprayed before entering the packing layer, which can easily cause problems such as the circulating water being carried away by the gas, resistance loss of the packing layer, and low packing utilization rate. Utility Model Content

[0004] The main objective of this invention is to provide a humidification device for a biological deodorization system, addressing the problems existing in the prior art by reducing gas short-circuiting, improving packing utilization, and more effectively mixing and contacting circulating water and odorous gases within the washing packing layer. It also reduces resistance loss within the packing layer and features a small footprint, making it particularly suitable for treating 5000m³ of wastewater. 3 Biological deodorization equipment with a capacity of less than [number] hours.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A humidification device for a biological deodorization equipment includes a spray layer, a packing layer, a circulating water tank, and an air distribution pipe arranged sequentially from top to bottom. The spray layer includes a circulating spray pipe, a plurality of nozzles disposed on the circulating spray pipe, and sealing plates located on both sides above the packing layer. The packing layer includes a gas-liquid mixing zone located below the spray layer and gas-liquid separation zones located on both sides of the gas-liquid mixing zone. The material density of the gas-liquid mixing zone is lower than that of the gas-liquid separation zone. The circulating water tank is connected to the gas-liquid mixing zone through a circulating water return pipe. The air distribution pipe is disposed through the gas-liquid mixing zone, and its surface is provided with a plurality of air distribution holes and drainage holes.

[0007] The air distribution pipe is a square pipe with several air distribution holes on its upper left and right surfaces, and several drainage holes on its lower surface.

[0008] The lower end of the sealing plate is inserted above the interface between the gas-liquid mixing zone and the gas-liquid separation zone.

[0009] A baffle is provided below the packing layer, and the circulating water return pipe passes through the baffle and the gas-liquid mixing zone in sequence.

[0010] The circulating water tank is equipped with an overflow port and a vent.

[0011] The circulating spray pipe is connected to the circulating water storage tank through a circulating device.

[0012] After adopting the above technical solution, the present invention has the following technical effects:

[0013] This invention utilizes a gas distribution pipe within the gas-liquid mixing zone to achieve both cross-flow and co-flow, thereby increasing the water-air contact area and delaying the contact time, resulting in uniform gas distribution. Furthermore, the gas distribution pipe evenly distributes gas around its perimeter, directly contacting the packing layer. This reduces the thickness of the packing layer, minimizing resistance loss and ensuring sufficient gas-liquid contact within the mixing zone. In the gas-liquid separation zone, it also reduces the loss of circulating water carried away by the gas, achieving demisting and water conservation. In the spray layer, a sealing plate separates the spray, ensuring that the fine water particles sprayed from the nozzles evenly cover the gas-liquid mixing zone of the packing layer, preventing them from flowing to the sides.

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] refer to Figure 1-3 As shown, this utility model discloses a humidification device for a biological deodorization equipment, which includes a spray layer 1, a packing layer 2, a circulating water tank 3 and an air distribution pipe 4 arranged sequentially from top to bottom;

[0025] The spray layer 1 includes a circulating spray pipe 11, a plurality of nozzles 12 disposed on the circulating spray pipe 11, and sealing plates 13 located on both sides above the packing layer 2. The sealing plates 13 are used to prevent water vapor from leaking to the two layers above the packing layer 2.

[0026] The packing layer 2 includes a gas-liquid mixing zone 21 located below the spray layer 1, and gas-liquid separation zones 22 located on both sides of the gas-liquid mixing zone 21; the material density of the gas-liquid mixing zone 21 is less than that of the gas-liquid separation zone 22.

[0027] The circulating water storage tank 3 is connected to the gas-liquid mixing zone 21 of the packing layer 2 through a circulating water return pipe 31;

[0028] The gas distribution pipe 4 is installed through the gas-liquid mixing zone 21, and its surface is provided with a number of gas distribution holes 41 and drainage holes 42.

[0029] Through the above scheme, this utility model sets up an air distribution pipe 4 inside the gas-liquid mixing zone 21, which has both cross-flow and co-flow, and can improve the water-air contact area and delay the water-air contact time, so as to achieve the effect of uniform air distribution. In addition, the air distribution pipe 4 emits air evenly around its perimeter and directly contacts the packing layer 2, which is equivalent to reducing the thickness of the gas penetrating the packing layer 2, thereby reducing the resistance loss of the packing layer 2. This allows for full contact between gas and liquid in the gas-liquid mixing zone 21, and reduces the loss of circulating water carried away by the gas in the gas-liquid separation zone 22, thus playing a role in demisting and saving water. In the spray layer 1, the sealing plate 13 is used for isolation, so that the fine water particles sprayed by the nozzle 12 can evenly cover the gas-liquid mixing zone 21 of the packing layer 2 and will not be lost to the sides.

[0030] The following are specific embodiments of the present invention.

[0031] refer to Figure 3 As shown, the air distribution pipe 4 is a square pipe with several air distribution holes 41 on its upper left and right surfaces, and several drainage holes 42 on its lower surface.

[0032] The lower end of the sealing plate 13 is inserted above the interface between the gas-liquid mixing zone 21 and the gas-liquid separation zone 22, so that there is no gap between the sealing plate 13 and the gas-liquid mixing zone 21, ensuring that water vapor will not be lost.

[0033] A baffle 5 is provided below the packing layer 2 to support the packing layer 2 and prevent water from seeping downwards from the packing layer 2; the circulating water return pipe 31 passes through the baffle 5 and the gas-liquid mixing zone 21 in sequence.

[0034] The aforementioned circulating water tank 3 is equipped with an overflow port and a vent port. The former is used to control the amount of water in the tank, and the latter is used to drain all the water.

[0035] The aforementioned circulating spray pipe 11 is connected to the circulating water storage tank 3 through a circulating device to realize the recycling of water.

[0036] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
