Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, in particular to a biological deodorizing tower. Background Art

[0002] A large amount of malodorous gas will be generated in the process of industrial production, municipal sewage, sludge treatment and garbage treatment. Malodorous gas not only has a serious impact on the ecological environment, but also has great harm to human health. It can cause central nervous system disorders and lesions, and cause chronic and acute diseases. Therefore, malodorous gas needs to be deodorized before discharge. Common treatment methods for malodorous gas include combustion, oxidation, absorption, adsorption, neutralization and biological methods. By physically, chemically and biologically treating malodorous gas, the material structure of malodorous gas is changed and the malodor is eliminated.

[0003] The biological deodorization is achieved by setting up multiple layers of biological fillers in the three-dimensional tower. When the malodorous gas passes through the biological fillers, the toxic and harmful malodorous substances in the fillers are adsorbed and decomposed by the biological fillers, thereby purifying the malodorous gas and achieving the purpose of deodorization. This treatment method not only has a good deodorization effect, but also does not cause secondary pollution to the environment, and is green and environmentally friendly.

[0004] For example, the Chinese patent with publication number CN105709591B discloses a biological deodorization tower, including a tower body, a partition sealed and connected to the inner side wall of the tower body is provided at the top of the tower body, the partition extends to the position close to the bottom of the tower body, the partition divides the tower body into two independent deodorization chambers, the positions corresponding to the two deodorization chambers at the top of the tower body are respectively provided with air intake pipes connected to the inside thereof, the air intake pipes are provided with air intake fans, the middle of the deodorization chamber is provided with a first support plate and a second support plate from top to bottom, the first support plate is provided with a deodorizing microbial filling layer, the upper surface of the second support plate is provided with a dehumidifying microbial filling layer, the outer side wall of the tower body is provided with a water tank, the water tank is connected to the deodorization chamber through a connecting pipe, the connecting pipes are respectively located above the first support plate and the second support plate of the two deodorization chambers, the connecting pipes are provided with a nozzle, and the top of the water tank is respectively provided with a water supply pipe and a nutrient solution tank connected to the inside thereof. The present invention has a simple structure and has both dehumidification and deodorization functions.

[0005] This patent has some shortcomings when used, such as: the device in this patent only deodorizes the malodorous gas through the deodorizing microbial filler layer, the deodorizing means are relatively single, and the deodorizing effect is relatively general; in addition, since the odor enters the deodorizing tower directly from top to bottom, the contact time with the deodorizing microbial filler layer is short, and the harmful substances in the malodorous gas are discharged to the outside without fully reacting with the microbial filler, which greatly reduces the overall deodorizing effect of the device. In view of this, we propose a biological deodorizing tower. Utility Model Content

[0006] The purpose of the utility model is to provide a biological deodorization tower to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a biological deodorization tower, comprising:

[0008] A tower body, wherein a microbial filler placement partition is fixed to the upper part of the inner cavity of the tower body, and an airflow dispersion mechanism is sequentially arranged in the inner cavity of the tower body and directly below the microbial filler placement partition, and the airflow dispersion mechanism includes a uniform layer, an air collection layer, partition one, partition two and partition three, the uniform layer and the air collection layer are both fixed to the inner wall of the tower body, and the air collection layer is fixedly installed directly below the uniform layer, and a guide groove connected to the inner cavity of the uniform layer is opened on the lower surface of the air collection layer, and the partition one, partition two and partition three are vertically distributed and fixedly installed in the inner cavity of the uniform layer from bottom to top in sequence;

[0009] An air outlet groove is provided on the inner wall of the tower body and close to the lower part of the gas collecting layer. An air delivery pipe is provided on the periphery of the tower body, and multiple output ends of the air delivery pipe all penetrate the outer wall of the tower body and extend into the air outlet groove;

[0010] A plurality of installation slots, wherein the plurality of installation slots are provided on the tower body and are located directly below the air outlet slot, wherein an air supply component is provided in the installation slot, and the air supply component provides breeze and delivers odor to the top of the tower body;

[0011] An annular water pipe, the annular water pipe is arranged in the inner cavity of the tower body and is located between the microbial filler placement partition and the uniform layer, and a plurality of mist nozzles equidistantly distributed in a circumference are installed on the annular water pipe;

[0012] The infusion component is located on the peripheral side of the tower body and is used to recover the liquid at the bottom of the inner cavity of the tower body and to infuse liquid into the annular water pipe.

[0013] In the technical scheme, a uniform layer and a gas collecting layer are arranged, and partition one, partition two and partition three are arranged in the inner cavity of the uniform layer. By utilizing protrusion one on partition one, multiple protrusions two on partition two and multiple rows of protrusions three on partition three, the odor entering the inner cavity of the tower body can be evenly distributed and fully contact with the microbial filler placed in the partition where the microbial filler is placed. This changes the situation in the traditional device where the odor can only react with local microbial fillers in a concentrated manner due to large airflow at the odor inlet and uneven odor distribution, improves the utilization rate of the microbial filler and the reaction area, and thus improves the odor treatment efficiency.

[0018] In the present technical scheme, an air supply component is provided, and a breeze is generated by the operation of the fan. The breeze is filtered through a dustproof net to prevent dust in the outside air from entering the inner cavity of the tower body. The air is guided by a guide plate to accelerate the speed at which air enters the inner cavity of the tower body. The water droplets that partially fall into the L-shaped groove are adsorbed by the water absorption layer to avoid adverse effects on the fan below. The breeze generated by the operation of the air supply component is used to transport the odor in the inner cavity of the tower body upward to prevent the odor from accumulating at the bottom of the inner cavity of the tower body, thereby accelerating the contact between the odor and the microbial filler, thereby improving the treatment efficiency of harmful substances in the odor.

[0019] In the above technical solution, further, the infusion assembly includes:

[0020] A liquid storage tank is arranged on the peripheral side of the tower body, and the liquid storage tank is connected with the bottom of the inner cavity of the tower body through a water pipe.

The top end of the liquid delivery pipe penetrates the inner top surface of the liquid storage tank and extends to the outside. The top end of the liquid delivery pipe penetrates the outer wall of the tower body and extends to the inner cavity of the tower body to be connected with the annular water pipe.

[0021] In the present technical solution, an infusion assembly is provided and driven by a water pump, so that the liquid in the liquid storage tank can be transported to the annular water pipe through the liquid delivery pipe and form mist water droplets under the action of multiple mist nozzles. The mist water droplets come into contact with the odor and enter the microbial filler in the microbial filler placement partition, thereby accelerating the growth of microorganisms in the microbial filler and further improving the filtering effect of microorganisms on harmful impurities in the odor.

[0022] In the above technical solution, further, multiple layers of evenly distributed activated carbon layers are arranged in the air outlet pipe at the top of the tower body.

[0023] In this technical solution, by providing multiple layers of activated carbon layers, the treatment of odor in the odor is further improved to ensure that the odor discharged to the outside is fully purified.

[0024] In the above technical solution, further, a cover plate is installed at the opening of the air outlet pipe at the top of the tower body.

[0025] In this technical solution, the cover plate can effectively protect the multiple activated carbon layers below.

[0026] The beneficial effects of the utility model are:

[0027] 1. The biological deodorization tower is provided with a uniform layer and a gas collecting layer, and partitions 1, 2 and 3 are provided in the inner cavity of the uniform layer. By utilizing protrusion 1 on partition 1, multiple protrusions 2 on partition 2 and multiple rows of protrusions 3 on partition 3, the odor entering the inner cavity of the tower body can be evenly distributed and fully contact with the microbial filler in the microbial filler placed in the partition. This changes the situation in the traditional device that the odor can only react with the local microbial filler in a concentrated manner due to the large airflow at the odor inlet and the uneven distribution of the odor, improves the utilization rate of the microbial filler and the reaction area, and thus improves the odor treatment efficiency.

[0028] 2.

[0043] Embodiment 1:

[0044] See also Figure 1 - Figure 6 As shown, this embodiment provides a biological deodorization tower, comprising:

[0045] A tower body 1, a microbial filler placement partition 2 is fixed to the upper part of the inner cavity of the tower body 1, an airflow dispersion mechanism is sequentially arranged in the inner cavity of the tower body 1 and directly below the microbial filler placement partition 2, the airflow dispersion mechanism includes a uniform layer 3, an air collection layer 4, a partition 1 6, a partition 2 8 and a partition 3 10, the uniform layer 3 and the air collection layer 4 are fixed to the inner wall of the tower body 1, and the air collection layer 4 is fixedly installed directly below the uniform layer 3, a guide groove 5 connected to the inner cavity of the uniform layer 3 is opened on the lower surface of the air collection layer 4, and the partition 1 6, the partition 2 8 and the partition 3 10 are vertically distributed and sequentially fixedly installed in the inner cavity of the uniform layer 3 from bottom to top;

[0046] An air outlet groove 12 is provided on the inner wall of the tower body 1 and close to the lower part of the gas collecting layer 4. An air delivery pipe 13 is provided on the periphery of the tower body 1, and multiple output ends of the air delivery pipe 13 all penetrate the outer wall of the tower body 1 and extend into the air outlet groove 12.

[0047] A plurality of mounting grooves 15 are provided on the tower body 1 and are located directly below the air outlet groove 12. An air supply component is provided in the mounting groove 15. The air supply component provides breeze and delivers odor to the top of the tower body 1.

[0048] An annular water pipe is arranged in the inner cavity of the tower body 1 and is located between the microbial filler placement partition 2 and the uniform layer 3. A plurality of mist nozzles 26 are installed on the annular water pipe and are equidistantly distributed in a circle;

[0049] An infusion assembly, which is located on the periphery of the tower body 1 and is used to recover the liquid at the bottom of the inner cavity of the tower body 1 and to infuse liquid into the annular water pipe;

[0050] The partition 1 6, the partition 2 8 and the partition 3 10 are all provided with a plurality of evenly distributed air holes, the partition 1 6 is provided with a protrusion 1 7 at the center of the lower surface, the partition 2 8 is provided with a plurality of evenly distributed protrusions 2 9 on the lower surface, and the partition 3 10 is provided with a plurality of rows of linearly equidistantly distributed protrusions 3 11 on the lower surface;

[0051] An annular mesh plate 14 is fixed inside the tower body 1 at the location where the partition plate 2 for the microbial filler is placed.

[0052] Among them, before use, the microbial filler needs to be evenly laid on the microbial filler placement partition 2. The bottom of the microbial filler placement partition 2 is provided with uniform air holes, which can facilitate the odor below to contact and react with the microbial filler; then the operator transports the odor to the inner cavity of the tower body 1 through the air pipe 13, and the odor flows in the air pipe 13, and is evenly transported to the air outlet groove 12 through multiple output ends and dissipates at the lower part of the inner cavity of the tower body 1, and multiple air supply components and infusion components are started. The air supply component works and sucks the outside air into the tower body 1 through the installation groove 15. The air supply component generates a breeze and transports the odor upward, so that the odor can contact and react with the microbial filler in the microbial filler placement partition 2. In this process, irregular odor enters the guide groove 5 and gathers at the center. Then the odor contacts the partition 6 and, under the action of the protrusion 7, spreads toward the air holes on the side of the protrusion 7. Then the odor enters the partition 6 and The odor comes into contact with the partition 28 and the partition 28. During this process, the odor will come into contact with the multiple protrusions 29 on the lower surface of the partition 28, and will be differentiated and evenly divided by the multiple protrusions 29 again, and then enter between the partition 28 and the partition 3 10. The odor that has been differentiated twice will come into contact with the multiple columns of protrusions 3 11 on the lower surface of the partition 3 10 again, and under the action of the multiple columns of protrusions 3 11, it will spread toward the multiple air holes on the partition 3 10. After three differentiations and even divisions, the odor is evenly distributed at the upper position of the uniform layer 3. When the infusion component is working, the liquid in the liquid storage tank 23 is transported to the annular water pipe through the liquid delivery pipe 25, and a uniform water mist is formed through a plurality of mist nozzles 26. Part of the water mist comes into contact with the odor and enters the microbial filler above, so that the microbial filler can quickly react with the harmful impurities in the odor, thereby accelerating the deodorization efficiency. Finally, the treated odor is transported to the outside from the top outlet pipe of the tower body 1.

[0053] By setting a uniform layer 3 and a gas collecting layer 4, and setting partitions 1 6, 2 8 and 3 10 in the inner cavity of the uniform layer 3, by utilizing protrusion 1 7 on partition 1 6, multiple protrusions 2 9 on partition 2 8 and multiple rows of protrusions 3 11 on partition 3 10, the odor entering the inner cavity of the tower body 1 can be evenly distributed and fully contact with the microbial filler in the microbial filler placed in the partition 2, which changes the situation in the traditional device that the odor can only react with the local microbial filler in a concentrated manner due to the large airflow at the odor inlet and the uneven distribution of odor, thereby improving the utilization rate of the microbial filler and the reaction area, thereby improving the odor treatment efficiency.

[0054] Embodiment 2:

[0055] This embodiment provides a biological deodorization tower, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the air supply component includes:

[0056] The shell 16 is fixedly installed in the inner cavity of the tower body 1 and is located at the corresponding mounting groove 15. An L-shaped groove is opened on the shell 16. A guide plate 17 is fixed at the bottom of the inner cavity of the L-shaped groove. A fan 18, a water absorption layer 19 and a protective mesh plate 20 are installed in sequence from bottom to top directly above the guide plate 17. The fan 18, the water absorption layer 19 and the protective mesh plate 20 are all fixed to the inner wall of the L-shaped groove. A dustproof net 21 fixed to the L-shaped groove is installed on the outer side of the guide plate 17. A protective mesh plate 22 is fixed at the mounting groove 15 and located on the outer side of the shell 16.

[0057] Among them, when the air supply component is working, the fan 18 is started, and the fan 18 works and generates negative pressure, so that the outside air can pass through the multiple air holes on the protective mesh plate 22 through the dustproof net 21 and be filtered by the dustproof net 21, and then the air is guided by the curved surface of the guide plate 17 and moves upward, and finally enters the inner cavity of the tower body 1 along the upper opening of the shell 16 and forms a breeze. The breeze can drive the odor diffused in the air outlet groove 12 directly above to move further upward, and contact the lower surface of the air collection layer 4, and then gather towards the center under the action of the guide groove 5. It is worth adding that when the infusion component humidifies the odor, the weight of the odor increases, but due to the action of the air supply component, the odor can still slowly drift upward along the inner cavity of the tower body 1, and contact the microbial filler in the partition 2 where the microbial filler is placed.

[0058] By setting up an air supply component, the fan 18 is used to generate a breeze, which is filtered through the dustproof net 21 to prevent dust in the outside air from entering the inner cavity of the tower body 1, and then guided by the guide plate 17 to accelerate the speed of air entering the inner cavity of the tower body 1. The water absorption layer 19 is used to absorb some water droplets that fall into the L-shaped groove to avoid adverse effects on the fan 18 below. The breeze generated by the air supply component when it is working is used to transport the odor in the inner cavity of the tower body 1 upward to prevent the odor from accumulating at the bottom of the inner cavity of the tower body 1, accelerate the contact between the odor and the microbial filler, and thereby improve the treatment efficiency of harmful substances in the odor.

[0059] Embodiment 3:

[0061] A liquid storage tank 23 is arranged on the peripheral side of the tower body 1, and the liquid storage tank 23 is connected to the bottom of the inner cavity of the tower body 1 through a water pipe. A water pump 24 is installed in the liquid storage tank 23, and a liquid delivery pipe 25 is installed at the output end of the water pump 24. The top end of the liquid delivery pipe 25 penetrates the inner top surface of the liquid storage tank 23 and extends to the outside. The top end of the liquid delivery pipe 25 penetrates the outer wall of the tower body 1 and extends to the inner cavity of the tower body 1 to be connected with the annular water pipe.

[0062] Among them, when the infusion component is working, the water pump 24 is started, and the water pump 24 can transport the liquid in the liquid storage tank 23 to the annular water pipe through the liquid delivery pipe 25, and under the action of multiple mist nozzles 26, mist water droplets are formed. It is worth adding that the nozzle ends of the multiple mist nozzles 26 in the present application are all arranged obliquely upward, and the nozzle ends of the mist nozzles 26 are facing one side of the axis of the annular water pipe; part of the water droplets will fall back to the bottom of the inner cavity of the tower body 1 under the action of gravity, and enter the liquid storage tank 23 again through the water pipe, thereby realizing recycling.

[0063] By setting up an infusion component and driving it with a water pump 24, the liquid in the liquid storage tank 23 can be transported to the annular water pipe through the liquid delivery pipe 25 and form mist water droplets under the action of multiple mist nozzles 26. The mist water droplets come into contact with the odor and enter the microbial filler in the microbial filler placement partition 2, accelerating the growth of microorganisms in the microbial filler and further improving the filtering effect of microorganisms on harmful impurities in the odor.
