Description

Technical Field

[0001] This utility model relates to the technical field of waste gas deodorization equipment, specifically to an ion exchange fiber deodorization device. Background Technology

[0002] In the field of waste gas treatment, traditional biological deodorization technology decomposes malodorous substances through the metabolism of microorganisms, but its application has significant limitations.

[0003] Biological filter deodorization technology primarily utilizes microorganisms attached to the filter media to adsorb, absorb, and degrade odorous gases. The odorous gases are first humidified by a humidifier before entering the biological filter. Inside the filter, the odorous gases distribute from the surface into the micropores within the filter media, coming into contact with the microorganisms. Through their physiological activities, the microorganisms decompose the organic matter in the odorous gases into simple inorganic substances (such as CO2 and H2O) and cytoplasm, thereby achieving deodorization.

[0004] While the aforementioned deodorization methods can be used to deodorize industrial waste gases, their equipment is bulky and requires sufficient space for microbial reactions, resulting in a significant increase in floor space. Furthermore, the cultivation cycle for biological strains can take several weeks, and microbial activity is easily affected by fluctuations in ambient temperature (optimal range 15-35℃) and humidity. Treatment efficiency drops sharply in low-temperature or dry environments, necessitating the configuration of an auxiliary system for heat preservation and humidification, further increasing equipment complexity and operating energy consumption. Utility Model Content

[0005] In view of this, the present invention provides an ion exchange fiber deodorization device. The present invention can adsorb harmful substances in the airflow through the spaced ion exchange fiber material. Moreover, the device has a small footprint, low wind resistance, and low energy consumption.

[0006] To solve the above-mentioned technical problems, this utility model provides an ion exchange fiber deodorization device, including a box body with a square structure and a closed inner cavity. Air inlets and outlets are provided on both sides of the box body, and both air inlets and outlets are connected to the inner cavity, allowing odors to enter the inner cavity through the air inlets.

[0007] Multiple lower supports are arranged in a linear pattern at the bottom of the inner cavity. Each lower support is vertically fixed with a deodorizing plate, which is made of ion exchange fiber material.

[0008] The inner cavity is also equipped with multiple upper supports corresponding to the lower support, and each upper support can be located on top of the deodorizing plate to reinforce and support the deodorizing plate.

[0009] The chamber is also equipped with several spray pipes, each with multiple spray heads. The liquid can be sprayed onto the deodorizing plate through the spray heads. A support frame is also provided horizontally in the inner cavity for each spray head. The support frame is located below the spray pipe, and the upper bracket is fixed to the bottom of the support frame. The liquid can pass through the support frame and be sprayed onto the deodorizing plate.

[0010] The bottom of the tank is also connected to a return pipe, and the other end of the return pipe is connected to a water tank, which facilitates the collection of liquid materials.

[0011] The water tank is also equipped with a return pipe, the other end of which is connected to the ends of several spray pipes. The return pipe is also equipped with a water pump, which facilitates the reuse of the liquid.

[0012] The water pump is located between the water tank and the spray pipe. There are also two ball valves on the return pipe. The ball valves can cut off the flow of liquid in the pipe. The two ball valves are located on both sides of the water pump, which facilitates the maintenance of the water pump.

[0013] The return pipe is also equipped with a check valve to prevent water from flowing back into the pipe, which acts as a one-way valve.

[0014] The water tank is also equipped with an overflow pipe.

[0015] The water tank is also equipped with a drain pipe, and the drain pipe is equipped with a drain valve.

[0016] The end of the overflow pipe is connected to the drain pipe, and this connection is located on the side of the drain valve away from the water tank.

[0020] 3. Stable operation and environmental adaptability: The ion exchange fiber maintains stable adsorption performance within the range of -10℃ to 50℃, completely eliminating the dependence of biological methods on ambient temperature (optimal range of 15-35℃) and humidity, and eliminating the need for heat preservation and humidification systems.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] This embodiment provides an ion exchange fiber deodorization device, such as... Figure 1As shown: It includes a rectangular box 100, which has a closed inner cavity 103. The side walls on both sides of the box 100 are provided with air inlets and outlets respectively. The air inlets and outlets are connected to the inner cavity 103 and are connected to air supply pipes. The inner cavity 103 is also rectangular. Multiple lower supports 104 are provided in the inner cavity 103. The two ends of each lower support 104 abut against the two sides of the inner cavity 103. The multiple lower supports 104 are arranged in a linear array. Each lower support 104 is fixed with a deodorizing plate 105. The deodorizing plate 105 is a cuboid plate structure. The two ends of the deodorizing plate 105 are also connected to the two sides of the inner cavity 103 and the bottom of the deodorizing plate 105 abuts against the bottom of the inner cavity 103. Each deodorizing plate 105 is made of ion exchange fiber material. The ion fiber adsorption exchange purification unit is composed of a set of fixed ion exchange fabrics. When gas passes through these materials, pollutants are adsorbed by the chemical bonds at the active sites of the ion exchange fibers. Ion exchange fibers exhibit high purification and adsorption efficiency in chemical adsorption. Compared to ion exchange resins, the exchange rate of ion exchange fibers is two orders of magnitude higher. This effect results in a filter with low air resistance and a small filtration volume. Odor-carrying chamber 100 has an inlet 101 and an outlet 102 on both sides, both connected to the inner cavity 103. After entering the inner cavity 103 through the inlet, the odor-carrying gas passes through the deodorizing plates 105, where harmful substances are adsorbed and filtered. The odor-carrying gas, filtered by multiple deodorizing plates 105, is then discharged through the outlet 102.

[0029] Specifically, the inner cavity 103 is also provided with multiple upper supports 106 corresponding to the lower support 104. The multiple upper supports 106 are located directly above the multiple lower supports 104. The lower supports 104 are located directly above the deodorizing plate 105. The upper supports 106 can reinforce the position of the deodorizing plate 105, thereby preventing the deodorizing plate 105 from shaking during operation.

[0030] Furthermore, a spray pipe 107 is connected to the top of the inner cavity 103. The spray pipe 107 is located directly above the multiple deodorizing plates 105. Multiple spray nozzles 108 are connected to the spray pipe 107. When the deodorizing plate 105 is working, the deodorizing effect will gradually decrease. The spray nozzles 108 can spray the liquid onto the deodorizing plate 105, thus ensuring the deodorizing effect of the deodorizing plate 105.

[0031] Preferably, a support frame 109 is also provided horizontally in the inner cavity 103. The support frame 109 is located between the spray pipe 107 and the deodorizing plate 105, and multiple upper supports 106 are located below the support frame 109. The support plate has a hollow structure, that is, the spray head 108 can spray the liquid onto the deodorizing plate 105.

[0032] It is worth mentioning that the bottom of the box 100 is also equipped with a return pipe 200, which is connected to the inner cavity 103. The other end of the return pipe 200 is connected to a water tank 201. In this way, liquid that cannot be absorbed by the deodorizing plate 105 will drip into the bottom of the inner cavity 103 and can then flow back into the water tank 201 through the return pipe 200 for recycling.

[0033] Preferably, a return pipe 202 is also connected to the water tank 201. The end of the return pipe 202 is connected to the end of the spray pipe 107. A water pump 203 is also connected to the return pipe 202. The water pump 203 is located between the water pump 203 and the spray pipe 107. That is, by controlling the operation of the water pump 203, the water in the water tank 201 can be diverted into the spray pipe 107, so that the sprayed liquid can be reused.

[0034] Preferably, the return pipe 202 is also equipped with two ball valves 204. The two ball valves 204 are located on both sides of the water pump 203. Both ball valves 204 are used to open and close the water flow in the return pipe 202. That is, the flow of liquid in the return pipe 202 is prohibited by the two ball valves 204, which makes it easier to disassemble and maintain the water pump 203. In this way, the liquid in the return pipe 202 will not be wasted in large quantities.

[0035] Furthermore, a check valve 205 is provided on the return pipe 202, which can be used to prevent the liquid in the spray pipe 107 from flowing back into the water tank 201.

[0036] Meanwhile, the water tank 201 is also connected to a water inlet pipe, which is equipped with a water inlet valve. The liquid can be added to the water tank 201 through the water inlet pipe, and the water inlet valve can be used to control the opening and closing of the water inlet pipe.

[0037] Furthermore, the water tank 201 is also connected to an overflow pipe 206, which allows liquid exceeding the height of the overflow pipe 206 to be discharged.

[0038] The water tank 201 is also connected to a drain pipe 207, which is equipped with a drain valve 208. The drain pipe 207 can actively discharge the liquid in the water tank 201. The drain pipe 207 is also equipped with a drain valve 208 to control the opening and closing of the drain pipe 207. Correspondingly, the overflow pipe 206 has an L-shaped structure, that is, the end of the overflow pipe 206 is connected to the drain pipe 207. The connection is located on the side of the drain valve 208 away from the water tank 201, that is, the liquid flowing out of the overflow pipe 206 can be discharged through the drain pipe 207.

[0039] Work style:

[0040] First, the liquid is added to the water tank 201. The normal storage capacity of the liquid in the water tank 201 is 1 cubic meter, and the pH value of the liquid is controlled between 7 and 9. Then, the water pump 203 is controlled to work so that the liquid enters the spray pipe 107 through the return pipe 202 and sprays the deodorizing plate 105 through the spray pipe 107 for 3-5 minutes. Then, the odor can be controlled to enter the inner cavity 103 through the air inlet for deodorization. The water tank 201 is also equipped with a pH value detection unit to detect the pH value in the water tank 201. When the pH value is lower than 7, the liquid needs to be adjusted by adding chemicals.

[0041] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
