Description

Technical Field

[0001] This invention relates to the field of dust removal equipment, specifically a wet cyclone dust collector with dust and ammonia removal functions. Background Technology

[0002] Traditional dust collectors are indeed effective at removing particulate matter; however, their removal efficiency is often less than ideal when dealing with complex environments containing gaseous pollutants such as ammonia. This is particularly pronounced in environments with mixed dust and ammonia contamination, often making effective integrated treatment difficult. This not only pollutes the working environment but also seriously threatens workers' occupational health. Furthermore, traditional wet scrubbers suffer from drawbacks such as high water consumption and the inability to recycle water resources. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a wet cyclone dust collector with dust and ammonia removal functions, which can simultaneously and efficiently remove dust and ammonia, effectively solving the problem of mixed dust and ammonia pollution, and also realizing the conservation and recycling of water resources.

[0004] To achieve the above objectives, this invention provides a wet cyclone dust collector with dust and ammonia removal functions, comprising a wet cyclone dust collector body, a water vapor separation device, and a wastewater treatment device. Inside the cylindrical wet cyclone dust collector body, cyclone fans I, II, III, and IV are sequentially installed via supports. At the center of the air inlet of the wet cyclone dust collector body, an ammonia concentration detector I and a ring sprayer I are installed via supports. Between cyclone fans II and III, a filter screen I, an ammonia concentration detector II, and a ring sprayer II are sequentially installed via supports. Behind cyclone fan IV, a filter screen II and a spraying device are arranged, with the spraying device spraying water to clean the filter screen II. In actual operation, the spraying device can automatically activate at preset time intervals or according to the degree of filter screen clogging. For example, when the pressure difference across the filter screen reaches a certain level, indicating that a certain amount of dust has accumulated on the filter screen, the spraying device will automatically activate, using water spray to remove the accumulated dust. This automated cleaning mechanism not only improves the efficiency of the filter screen but also reduces the need for manual cleaning, lowering maintenance costs. A centrifugal fan is installed behind the spraying device, and the inner surface of the wet cyclone dust collector where the centrifugal fan is mounted is equipped with spiral guide lines. These guide lines have a pitch of 20-40mm and are designed to optimize the water flow trajectory under centrifugal force. When the centrifugal fan starts, its powerful centrifugal force throws water from the fan center to the outer wall. At this time, the spiral guide lines begin to function, spiraling around the inside of the fan to effectively guide the centrifugally ejected water into the pre-set drain pipe. This design not only improves the efficiency of water discharge but also ensures the continuity and uniformity of the water flow, thereby reducing water accumulation and stagnation on the inner wall of the fan. The presence of the spiral guide line allows the water to flow more smoothly to the sewage pipe, reducing the friction and resistance of the water flow inside the fan. The rear end of the wet cyclone dust collector is connected to the water vapor separation device through a tapering tube. The lower end of the water vapor separation device is connected to the sewage treatment device through a sewage pipe. An exhaust pipe is installed at the upper end of the water vapor separation device. A high-pressure water spray device is installed on one side of the sewage treatment device, and an ammonia removal agent storage box and water outlet pipe are installed on the other side. The water outlet pipe is connected to the annular sprayer I, annular sprayer II and spraying device inside the wet cyclone dust collector through a support. The water outlet pipe has built-in stirring blades.

[0005] As a further improvement of the present invention, each cyclone fan I, cyclone fan II, cyclone fan III, and cyclone fan IV has a small nozzle vertically mounted at the bottom of its blades. The small nozzle has a small top nozzle and a large central nozzle. Treated water from the wastewater treatment device enters the wet cyclone dust collector body through an outlet pipe and support frame. Water is supplied to the small nozzles via pipes and a water rotary joint. These nozzles are designed to spray water mist containing an ammonia remover. This design cleverly combines the dynamics of the cyclone fan blade rotation with the physical properties of water mist capturing dust. When the blades rotate, their centrifugal force breaks the water droplets into finer particles, thereby greatly increasing the contact area between the water mist and the dust. These refined water mist particles can effectively capture dust particles in the air.

[0006] As a further improvement of the present invention, the water vapor separation device includes a cyclone device and a cyclone device cylinder wall. The water vapor separation device has a built-in cyclone device, and a flow-guiding spiral plate is fixedly installed on the surface of the cyclone device cylinder wall. Small baffles are fixed at equal intervals on the lower surface of the flow-guiding spiral plate. The flow-guiding spiral plate is 100-150 mm wide and has a pitch of 200-300 mm. The height of the small baffles is 50-75 mm, and the interval between two small baffles is 200-300 mm, increasing the centrifugal efficiency and enabling better separation of water vapor. When the airflow containing water vapor enters the cyclone device, the airflow is forced to rotate along the spiral channel inside the device. This rotation generates a large centrifugal force, causing water, due to its larger mass, to be thrown towards the outer wall of the channel, while the lighter air remains in the central area and continues to flow. This separation effect is significant, ensuring that water vapor in the airflow is effectively collected and removed. The bottom of the cyclone device is directly opposite the bottom baffle of the cyclone device. The conical top of the bottom baffle of the cyclone device is fixed to the bottom of the water vapor separator by the bottom bracket of the baffle. The lower end of the water vapor separator is connected to the main sewage pipe of the sewage discharge pipe through a pipeline. The lower part of the main sewage pipe is connected to the sewage treatment device through sewage pipe branch pipes I, II, III, IV and V, which are set at equal intervals. The upper part of the main sewage pipe is connected to the main body of the wet cyclone dust collector through the upper sewage pipe, and the opening of the upper sewage pipe is directly opposite the centrifugal fan.

[0007] As a further improvement of the present invention, the sewage treatment device includes a filter device and a rotating baffle. The filter device is installed inside the sewage treatment device, and the rotating baffle is installed on the side of the sewage treatment device. The sewage treatment device is installed in a water tank, and a high-pressure water spray device is fixedly installed at the rear of the sewage treatment device. Small holes are arranged in a matrix on one side of the sewage treatment device that is in contact with the high-pressure water spray device. The high-pressure water spray device is connected to a water supply pipe through an inlet pipe, and the water tank is connected to the main body of a wet cyclone dust collector through an outlet pipe and a support.

[0008] As a further improvement of the present invention, the filtration device includes filter screen I and filter balls I, with filter balls I, filter balls II, filter balls III, filter balls IV and filter balls V sequentially filled between filter screen I, filter screen II, filter balls III and filter balls IV, and the diameters of filter balls I, filter balls II, filter balls III and filter balls IV are 200, 100, 50 and 25 mm, respectively.

[0009] As a further improvement of the present invention, the front end of the wet cyclone dust collector is supported by a bracket, and the rear end is supported by a pipe on the sewage discharge pipe.

[0010] As a further improvement of the present invention, the ammonia remover placed in the ammonia remover storage box is mainly composed of green leafy plants rich in oxalic acid.

[0011] Compared with existing technologies, this invention has the following advantages: By adding an ammonia concentration detector I to the main body of the wet cyclone dust collector, the invention can detect the ammonia concentration in the airflow in real time and automatically adjust the dosage of the ammonia removal agent based on the monitoring results. This effectively removes dust and ammonia from the air, ensuring more precise and efficient use of the ammonia removal agent and saving on its dosage. Furthermore, this invention is equipped with a wastewater treatment device with a self-cleaning function, which can filter wastewater, allowing for water recycling and effectively realizing water resource conservation. Self-cleaning filtration of residue not only reduces environmental pollution but also lowers operating costs and improves the system's economic efficiency. The self-cleaning function also reduces the need for manual cleaning, making operation simpler and maintenance costs lower. Attached Figure Description

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2As shown, this is a wet cyclone dust collector with dust and ammonia removal functions. Inside the cylindrical wet cyclone dust collector body 1, cyclone fans I 131, II 132, III 133, and IV 134 are sequentially installed via supports. At the center of the air inlet of the wet cyclone dust collector body 1, an ammonia concentration detector I 111 and an annular sprayer I 121 are installed via supports. Between cyclone fans II 132 and III 133, filter I 141, ammonia concentration detector II 112, and an annular sprayer II 122 are sequentially installed via supports. Behind cyclone fan IV 134, filter II 142 and a spraying device 143 are located. The spraying device 143 sprays water to clean filter II 142. In actual operation, the spraying device 143 can automatically start at preset time intervals or according to the degree of filter clogging. For example, when the pressure difference across the filter reaches a certain level, it indicates that a certain amount of dust has accumulated on the filter. At this time, the spraying device 143 will automatically start, using water spray to remove the accumulated dust. This automated cleaning mechanism not only improves the working efficiency of the filter but also reduces the need for manual cleaning, lowering maintenance costs. A centrifugal fan 15 is installed behind the spraying device 143. The inner surface of the wet cyclone dust collector body 1 where the centrifugal fan 15 is installed is provided with spiral guide lines 151. The pitch of these spiral guide lines 151 is 20-40mm, designed to optimize the movement trajectory of the water flow under centrifugal force. When the centrifugal fan 15 starts, its powerful centrifugal force throws water from the center of the fan to the outer wall. At this time, the spiral guide lines 151 begin to function, spiraling around the inside of the fan to effectively guide the centrifugally thrown water flow into the pre-set drain pipe 24. This design not only improves the efficiency of water discharge but also ensures the continuity and uniformity of the water flow, thereby reducing the accumulation and retention of water on the inner wall of the fan. The presence of the spiral guide line 151 allows the water to flow more smoothly to the sewage pipe 24, reducing the friction and resistance of the water flow inside the fan. The rear end of the wet cyclone dust collector body 1 is connected to the water vapor separation device 2 through the tapering pipe 16. The lower end of the water vapor separation device 2 is connected to the sewage treatment device 3 through the sewage pipe 24. The upper end of the water vapor separation device 2 is equipped with an exhaust pipe 23. The sewage treatment device 3 is equipped with a high-pressure water spray device 33 on one side and an ammonia removal agent placement box 36 and a water outlet pipe 35 on the other side. The water outlet pipe 35 is connected to the annular sprayer I 121, annular sprayer II 122 and spraying device 143 inside the wet cyclone dust collector body 1 through the bracket 4. The water outlet pipe 35 has a built-in stirring blade 37.

[0024] like Figure 3As shown, each cyclone fan I 131, cyclone fan II 132, cyclone fan III 133, and cyclone fan IV 134 has a small nozzle 135 vertically mounted at the bottom of its blades. The small nozzle 135 has a small top nozzle 1351 and a large central nozzle 1352. The treated water in the wastewater treatment device 3 enters the wet cyclone dust collector body 1 through the outlet pipe 35 and the support 4. Water is supplied to the small nozzles 135 through pipelines and water rotary joints. These nozzles are designed to spray water mist containing ammonia removal agent. This design cleverly combines the dynamics of the cyclone fan blade rotation with the physical properties of water mist capturing dust. When the blades rotate, their centrifugal force breaks the water droplets into finer particles, thereby greatly increasing the contact area between the water mist and the dust. These fine water mist particles can effectively capture dust particles in the air; the cyclone fans I 131, II 132, III 133 and IV 134 are driven by eccentric motors and gear disks.

[0025] like Figure 2 , Figure 4 , Figure 9 As shown, the water vapor separation device 2 includes a cyclone device 21. The cyclone device 21 is built into the water vapor separation device 2. A guiding spiral plate 25 is fixedly installed on the surface of the cyclone device cylinder wall 211 of the cyclone device 21. Small partitions 26 are fixed at equal intervals on the lower surface of the guiding spiral plate 25. The guiding spiral plate 25 is 100-150mm wide and has a pitch of 200-300mm. The small partitions 26 are 50-75mm high, and the interval between two small partitions is 200-300mm, increasing centrifugal efficiency and allowing for better water vapor separation. When the airflow containing water vapor enters the cyclone device 21, the airflow is forced to rotate along the spiral channel inside the device. This rotation generates a large centrifugal force, causing water, due to its greater mass, to be thrown towards the outer wall of the channel, while the lighter air remains in the central area and continues to flow. This separation effect is significant, ensuring that water vapor in the airflow is effectively collected and removed. The bottom of the cyclone device 21 is directly opposite the bottom partition 22 of the cyclone device. The conical top 221 of the bottom partition 22 of the cyclone device is fixedly installed at the bottom of the water vapor separator 2 by the bottom support 222 of the partition. The lower end of the water vapor separator 2 is connected to the main sewage pipe 241 of the sewage pipe 24 through a pipeline. The lower part of the main sewage pipe 241 is connected to the sewage treatment device 3 through sewage pipe branch pipes I 243, II 244, III 245, IV 246 and V 247, which are set at equal intervals. The upper part of the main sewage pipe 241 is connected to the wet cyclone dust collector body 1 through the upper sewage pipe 242, and the opening of the upper sewage pipe 242 is directly opposite the centrifugal fan 15.

[0026] like Figures 5 to 9As shown, the wastewater treatment device 3 includes a filter device 31 and a rotating baffle 32. The filter device 31 is installed inside the wastewater treatment device 3, and the rotating baffle 32 is installed on the side of the wastewater treatment device 3. The wastewater treatment device 3 is installed in a water tank 34, and a high-pressure water spray device 33 is fixedly installed at the rear of the wastewater treatment device 3. Small holes 38 are arranged in a matrix on one side of the wastewater treatment device 3 that is in contact with the high-pressure water spray device 33. The high-pressure water spray device 33 is connected to a water supply pipe through an inlet pipe 331, and the water tank 34 is connected to the wet cyclone dust collector body 1 through an outlet pipe 35 and a support 4. The filter device 31 includes filter screen I 311 and filter balls I 312. Filter balls I 312, II 313, III 315, IV 317 and V 319 are sequentially filled between filter screens I 311, II 314, III 316 and IV 318. The diameters of filter balls I 312, II 314, III 316 and IV 318 are 200, 100, 50 and 25 mm, respectively.

[0027] To provide a circulating water path and ensure that the main body 1 of the wet cyclone dust collector is at the appropriate height, such as Figure 1 As shown, the front end of the wet cyclone dust collector body 1 is supported by a bracket 4, and the rear end is supported by a drain pipe 242.

[0028] The ammonia remover placed in the ammonia remover storage box 36 mainly consists of leafy green plants rich in oxalic acid. The steps for preparing the oxalic acid solution are as follows:

[0029] Step 1: Select plant materials

[0030] First, select plant samples, including leafy green plants rich in oxalic acid such as spinach and amaranth. These plants are not only high in oxalic acid but also readily available, making them ideal raw materials for preparing oxalic acid solutions. During the selection process, these plants must be carefully washed to remove any attached soil and impurities, ensuring the purity of the raw materials.

[0031] Step 2: Drying and Grinding

[0032] After cleaning, the plant samples need to be air-dried or dried using a drying device to remove excess moisture. The dried plant samples, such as leaves and roots, are then ground into a fine powder using a grinder. This step is crucial because the fine powder significantly increases the surface area in contact with water, thus allowing for more effective release of oxalic acid during subsequent extraction.

[0033] Step 3: Extract oxalic acid

[0034] The ground plant powder is mixed with water to form a homogeneous suspension. The suspension is then heated to 70 degrees Celsius and maintained at this temperature for a period of time. During this process, oxalic acid is released from the plant cells, dissolves in the water, and forms an oxalic acid solution.

[0035] Step 4: Filtering and Collection

[0036] After cooling, the oxalic acid solution needs to be filtered to completely remove solids, such as incompletely dissolved plant residues. This step ensures the purity and transparency of the oxalic acid solution, facilitating subsequent use and storage. The filtered oxalic acid solution is collected and prepared for use in the ammonia removal process of a wet scrubber.

[0037] The flow rate of sewage pipe 24 is calculated using the following formula:

[0038]

[0039]

[0040] In the formula:

[0041] Total sewage flow;

[0042] The water flow rate of the main sewage pipe 241;

[0043] The water flow rate of pipe 242 on the sewage pipe;

[0044] The water flow rate of branch pipe I243 of the sewage pipe;

[0045] The water flow rate of branch pipe II244 of the sewage pipe;

[0046] The water flow rate of branch pipe Ⅲ245 of the sewage pipe;

[0047] The water flow rate of sewage branch pipe IV246;

[0048] The water flow rate of branch pipe V247 of the sewage pipe.

[0049] The radius of the branch pipe is calculated using the following formula:

[0050]

[0051]

[0052]

[0053] In the formula:

[0054] Let i be the water flow rate of branch pipe i;

[0055] Let be the water flow velocity in branch pipe i;

[0056] Let i be the cross-sectional area of ​​branch pipe i;

[0057] Let i be the radius of branch i;

[0058] The radius of branch i after correction;

[0059] This is the pipe diameter correction factor for branch pipe i;

[0060] When in use, this invention works as follows:

[0061] In operation, step 1: The dust-laden airflow enters through the inlet of the wet cyclone dust collector body 1. Simultaneously, ammonia concentration detector I111 monitors the ammonia concentration in the dust-laden airflow. Annular sprayer I121 adjusts the concentration of the ammonia-removing agent according to the ammonia concentration detected by the detector, spraying a water mist containing the ammonia-removing agent. The water mist is broken up by cyclone fans I131 and II132, with the water droplets being broken into finer particles, greatly increasing the contact area with the dust particles. This refined water mist effectively captures dust particles and separates them from the airflow. At the same time, the ammonia-removing agent reacts chemically with the ammonia in the dust, thereby neutralizing the ammonia.

[0062] Step 2: The water mist containing the captured dust particles is initially filtered by filter screen I141 to reduce the dust concentration. Then, it passes through ammonia concentration detector II112 to monitor the ammonia concentration in the airflow again. The concentration of ammonia removal agent is adjusted by the annular sprayer II122. The water mist then passes through cyclone fans III133 and IV134 to ensure that the water mist comes into full contact with the dust particles, capturing the dust particles. Under the action of the ammonia removal agent, the ammonia in the airflow is completely removed, ensuring that the ammonia concentration in the airflow is reduced to a safe level. Finally, it undergoes secondary filtration through filter screen II142.

[0063] Step 3: The filtered water-containing airflow undergoes preliminary dehydration by the centrifugal fan 15. The centrifugal water flow follows the spiral guide line 151 and flows through the upper pipe 242 of the drain pipe into the main drain pipe 241 of the drain pipe 24. The pre-dehydrated airflow enters the water vapor separator 2 through the converging pipe 16. Under the swirling guidance of the swirling device 21, larger water droplets are thrown onto the wall due to centrifugal force. The airflow drifts along the guide spiral plate 25 to the bottom of the water vapor separator 2. At the bottom baffle 22 of the swirling device, the dry airflow rises along the baffle and is discharged from the water vapor separator 2 through the exhaust pipe 23. The water droplets slide down the bottom baffle 22 of the swirling device under the influence of gravity and fall into the drain pipe 24.

[0064] Step 4: Wastewater flows into the wastewater treatment device 3 through branch pipes I 243, II 244, III 245, IV 246, and V 247 of the sewage pipe 24. The wastewater is first initially filtered by filter screen I 311, and then further filtered by filter balls I 312, II 314, III 316, and IV 318, whose radii gradually decrease. These filter balls are made of a special porous material and are designed to provide deep filtration, effectively removing finer suspended particles and sediments. As the radius of the filter balls gradually decreases, they can capture increasingly smaller pollutants, ensuring deep purification of the water. Finally, the clean water flows through the outlet pipe 35 into the water area of ​​the wet cyclone dust collector 1. Before entering the water area, the material in the ammonia removal agent storage tank 36 enters the outlet pipe 35 through a pipeline and is deeply mixed by the stirring blades 37.

[0065] During self-cleaning, step 1: Open the rotating partition 32, open the upper partition plate of filter screen I 311 and the lower partition plate of filter screen V 319, and close the upper and lower parts of the filter device 31 to ensure that the upper and lower parts of the filter device 31 can be effectively isolated.

[0066] Step 2: Activate the high-pressure water spray device 33, which sprays high-pressure water into the sewage treatment device 3 through a series of small holes 38, effectively washing the filter residue out of the filter device 31. The washed-out residue will then flow into the water tank 34 below, preparing for subsequent treatment and collection.

[0067] Step 3: After the cleaning process is complete, close the rotating baffle 32, the upper baffle of filter screen I 311, and the lower baffle of filter screen V 319. Closing these baffles indicates the end of the self-cleaning step and also ensures that the filtration device can return to normal operation and continue its efficient wastewater treatment task.

[0068] In summary, the wet cyclone dust collector with dust and ammonia removal functions of this invention, by adding an ammonia concentration detector I111 to the main body 1 of the wet cyclone dust collector to sense the ammonia concentration in the airflow in real time, and automatically adjusting the amount of ammonia removal agent used based on the monitoring results, ensures more precise and efficient use of the ammonia removal agent and saves on the amount of ammonia removal agent used. Furthermore, this invention is also equipped with a wastewater treatment device 3 with a self-cleaning function, which can effectively realize the recycling of water resources. By filtering residue through self-cleaning, not only is environmental pollution reduced, but operating costs are also lowered, improving the system's economic efficiency. The self-cleaning function also reduces the need for manual cleaning, making operation simpler and maintenance costs lower.
