Description

Technical Field

[0001] This invention relates to the technical field of sludge treatment. More specifically, this invention relates to a sludge thermal drying and deodorization mechanism and method. Background Technology

[0002] During the sludge drying process, the decomposition of organic matter and evaporation of water in the sludge due to high temperatures release a large amount of waste gas containing malodorous components. This waste gas is usually accompanied by a high concentration of dust particles. To effectively control odor emissions, existing waste gas treatment systems generally adopt chemical scrubbing processes: first, deodorizing liquid is evenly sprayed onto the surface of the packing layer in the packed tower through a spray device, allowing the waste gas to pass through the packing layer and fully contact the liquid adhering to the packing, thus achieving the purpose of deodorization and purification.

[0003] However, dust in the exhaust gas easily deposits and caking on the surface of the packing material after mixing with the chemical solution. This scaling not only significantly reduces the specific surface area and mass transfer efficiency of the packing material, but also causes blockage of airflow channels, increases system resistance, and seriously affects the flow and purification effect of exhaust gas. To alleviate this problem, existing technologies often attempt to remove the scale by increasing the water pressure of the spray system and using high-pressure water flow to flush the packing material. However, because the packing layer is usually designed to be relatively thick (to ensure sufficient gas-liquid contact time and treatment efficiency), the energy of the high-pressure water flow rapidly decays after penetrating the upper packing layer, making it difficult to effectively reach and clean the lower packing layer, resulting in severe blockage and scaling in the deep areas. Summary of the Invention

[0004] To overcome the problem that high-pressure water flow is unable to effectively clean the lower packing material due to energy attenuation, leading to blockage and scaling in deep areas, this invention provides a sludge thermal drying and deodorization mechanism and a drying and deodorization method.

[0005] The technical implementation scheme of the present invention is as follows: a sludge thermal drying and deodorization mechanism, comprising a cylindrical cylinder and a square tube; the square tube is connected to the cylindrical cylinder; the cylindrical cylinder and the square tube are fixedly connected; it also includes a baffle, a hollow rod, a long tube, a pipe, and a spray assembly; a baffle is fixedly connected to the inner side of the cylindrical cylinder; the baffle has several circular holes; the baffle is used to receive the packing material; a hollow rod is connected to the baffle and is connected to the cylindrical cylinder; a long tube is fixedly connected to the hollow rod; several pipes are connected to the long tube and are fixedly connected to the long tube, passing through the hollow rod; small holes with upward openings are opened on the pipes; a spray assembly is connected to the cylindrical cylinder and is used to spray liquid onto the packing material; it also includes an expansion assembly, which includes a round rod and a driving unit; a driving unit is connected to the hollow rod; several round rods are connected to the driving unit; the driving unit is used to drive the round rod to move up and down.

[0006] More preferably, the spray assembly includes a second pipe and a nozzle; the second pipe is fixedly connected to the first cylinder; a plurality of nozzles are connected to the second pipe; and the nozzles are fixedly connected to the second pipe.

[0008] More preferably, the drive unit includes a sleeve, an electric push rod, and a connecting block 1; the sleeve is slidably connected to the outside of the hollow rod, and the sleeve is fixedly connected to the round rod; the sleeve has several through slots, and the long tube is located inside the corresponding through slot; the electric push rod is fixedly connected to the round rod 1; the telescopic end of the electric push rod is fixedly connected to the connecting block 1, and the connecting block 1 is rotatably connected to the sleeve.

[0009] More preferably, it also includes a protective component, which includes a second cylinder and a second connecting block; the second cylinder is fixedly connected to the inner side of the first cylinder; the second connecting block is slidably connected to the inner side of the second cylinder, and the second connecting block is rotatably connected to the sleeve.

[0010] More preferably, it also includes a barrier net; each round rod is fixedly connected to a corresponding pipe; the barrier net is elastic.

[0011] More preferably, it also includes a pipe three; several pipes three are connected to the long pipe, and the pipes three pass through the hollow rod; a cavity is formed between the hollow rod and the baffle, and the cavity is connected to the pipe three; several channels one are opened on the baffle, and channels one is connected to the cavity; several channels two are opened on the baffle, and channels two are connected to the corresponding channels one.

[0012] More preferably, it also includes a second intercepting net; the second intercepting net is fixedly connected to the inner side of the cylinder.

[0013] A drying deodorization method includes the following steps: Step 1: Waste gas input and chemical spraying. The waste gas enters the first cylinder through the square pipe, and the chemical spray is sprayed onto the packing layer above the baffle through the second pipe and the nozzle. The waste gas passes through the packing layer and reacts with the chemical to achieve preliminary deodorization. Step 2: Stirring and optimizing distribution. Start the motor to drive the hollow rod to rotate, so that the pipeline is stirred by the packing layer, eliminating the channeling of the medicine and improving the purification effect of the exhaust gas.

[0014] Compared with the prior art, the present invention has the following advantages: First, by evenly distributing the first pipe inside the packing layer, it can fully flush all areas of the packing layer, thereby avoiding the problem of low efficiency caused by flushing only from the top of the packing layer. In addition, the first pipe can lift the packing upwards during flushing, so that its position and angle are constantly changing, thereby allowing the cleaning liquid to cover all parts of the packing and improving the flushing effect. At the same time, the first pipe also has a stirring function, which can eliminate channeling phenomenon and promote the more even distribution of the liquid on the surface of the packing, thereby improving the exhaust gas purification effect. Second, the expansion movement of the round rod and the corresponding pipe loosens the packing layer, avoiding the problem of the packing layer becoming compacted after flushing and interfering with the purification operation. At the same time, the intercepting net intercepts the packing, preventing it from moving into the gap between the round rod and the pipe and being crushed, thus achieving a protective function. In addition, the intercepting net, which has a protective function, can also increase the disturbance area of ​​the packing, thereby enhancing the mixing effect, more effectively eliminating channeling, and further improving the exhaust gas purification effect. Third, a cavity, channel one, and channel two are opened in the baffle, so that the cleaning fluid can be sprayed upward from channel two to rinse the bottom packing, thereby improving the overall rinsing effect.

Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: A sludge thermal drying and deodorization mechanism, such as Figures 1-7 As shown, it includes a cylindrical tube 1 and a square tube 2; the square tube 2 is connected to and welded to the cylindrical tube 1; it also includes a baffle 3, a hollow rod 4, a long tube 5, a pipe 6, and a spray assembly; the baffle 3 is fixedly connected to the inner side of the cylindrical tube 1; the baffle 3 has several round holes; the hollow rod 4 is connected to the cylindrical tube 1 and the baffle 3; the long tube 5 is fixedly connected to the hollow rod 4; several pipes 6 are connected to and fixedly connected to the long tube 5, and the pipes 6 pass through the hollow rod 4; the pipes 6 have small holes with upward openings; the spray assembly is connected to the cylindrical tube 1.

[0019] The spray assembly includes a second pipe 201 and a nozzle 202; the second pipe 201 is fixedly connected to the first cylinder 1; and several nozzles 202 are connected and fixedly connected to the second pipe 201.

[0020] First, connect the pipelines: connect the exhaust port of the drying mechanism to the square pipe 2, the liquid delivery pipe to pipe 201, the waste liquid discharge pipe to the lower end of cylinder 1, the cleaning liquid delivery pipe to the long pipe 5, and the gas delivery pipe to the hollow rod 4. A fan is installed on the gas delivery pipe to provide suction, causing the waste gas to flow sequentially through the square pipe 2, the upper part of cylinder 1, the packing layer, the lower part of cylinder 1, the hollow rod 4, and the gas delivery pipe. During this process, the liquid delivery pipe delivers liquid to pipe 201, and the liquid is sprayed downwards through nozzle 202. The packing layer is supported above the baffle 3. This allows the liquid medicine to be sprayed onto the surface of the packing material. When the exhaust gas passes downward through the packing layer, it will come into full contact with the liquid medicine on the surface of the packing material and undergo a chemical reaction, thereby achieving the purpose of deodorization and purification. After the liquid medicine reacts, it forms waste liquid, which flows downward through the round hole on the baffle 3 and then collects at the lower part of the cylinder 1. The waste liquid is then discharged through the waste liquid discharge pipe. At this time, the amount of waste liquid discharged is regulated by the waste liquid discharge pipe so that a certain amount of waste liquid can always accumulate at the lower part of the cylinder 1. This part of waste liquid seals the lower opening of the cylinder 1, forming a liquid seal layer to prevent the exhaust gas from being discharged from the lower opening of the cylinder 1.

[0021] During regular cleaning, the drying unit suspends exhaust gas discharge, the chemical delivery pipe stops delivering chemical solution, and the cleaning solution delivery pipe delivers high-pressure cleaning solution to long pipe 5. The cleaning solution flows into pipe 6 through long pipe 5 and is then sprayed upwards from the small holes in pipe 6. This high-pressure cleaning solution impacts the packing material from bottom to top. Since pipe 6 is evenly distributed inside the packing layer, it can thoroughly flush all areas of the packing layer, removing residual dirt and restoring the specific surface area, mass transfer efficiency, and permeability of the packing layer to ensure subsequent exhaust gas treatment efficiency. Furthermore, when the high-pressure cleaning solution impacts the packing material from bottom to top, the packing material is lifted upwards by the cleaning solution, then falls downwards under gravity, and is then lifted upwards again by the high-pressure cleaning solution. This repeated process causes the position and angle of the packing material to change continuously, allowing the cleaning solution to thoroughly flush all parts of the packing material, which is beneficial for improving the flushing effect.

[0022] It also includes a stirring assembly, which includes a motor 203, a gear 204, and a gear ring 205; the hollow rod 4 is rotatably connected to the cylinder 1; the hollow rod 4 is rotatably connected to the baffle 3; the motor 203 is bolted inside the cylinder 1; the output shaft of the motor 203 is fixedly connected to the gear 204, which is made of alloy material; the gear ring 205 is fixedly connected to the hollow rod 4, and the gear ring 205 meshes with the gear 204. The motor 203 drives the gear 204 to rotate, the gear 204 drives the gear ring 205 to rotate, and the gear ring 205 drives the hollow rod 4 to rotate.

[0023] During the waste gas purification process, channeling may occur on the surface of the packing material, preventing the liquid from being evenly distributed and flowing across the packing surface. This results in a small contact area between the waste gas and the liquid, affecting the waste gas purification efficiency. Therefore, during the waste gas purification process, the motor 203 is periodically started. The motor 203 drives the gear 204 to rotate, which in turn drives the gear ring 205 to rotate. The gear ring 205 drives the hollow rod 4 to reciprocate, which in turn drives the long pipe 5 and the pipe 6 to reciprocate. This allows the pipe 6 to agitate the packing material, eliminating channeling and ensuring that the liquid is more fully distributed on the packing surface, thereby improving the waste gas purification effect.

[0024] It also includes an expansion assembly, which includes a round rod 206 and a drive unit; the drive unit is connected to the hollow rod 4; and several round rods 206 are connected to the drive unit.

[0025] The drive unit includes a sleeve 207, an electric push rod 208, and a connecting block 209. The sleeve 207 is slidably connected to the outside of the hollow rod 4. The sleeve 207 is fixedly connected to the round rod 206. The sleeve 207 is made of alloy material. Several through slots 91 are opened on the sleeve 207, and the long tube 5 is located inside the corresponding through slot 91. The electric push rod 208 is fixedly connected to the round rod 1. The telescopic end of the electric push rod 208 is fixedly connected to the connecting block 209. The connecting block 209 is rotatably connected to the sleeve 207. The electric push rod 208 drives the connecting block 209 to move upward, and the connecting block 209 drives the sleeve 207 to move upward.

[0026] It also includes a protective component, which includes a second cylinder 2010 and a second connecting block 2011; the second cylinder 2010 is welded to the inner side of the first cylinder 1; the second connecting block 2011 is slidably connected to the inner side of the second cylinder 2010, and the second connecting block 2011 is rotatably connected to the sleeve 207. Through the sliding sealing structure formed by the second cylinder 2010 and the second connecting block 2011, the motor 203 and the electric push rod 208 are isolated from the working area, thus playing a protective role.

[0027] During the rinsing process, the packing material is pushed upwards and then falls downwards, causing the packing layer to become too compact, which affects the flow of exhaust gas and interferes with exhaust gas purification. Therefore, an expansion component is installed. After rinsing, the electric push rod 208 is activated. The electric push rod 208 drives the connecting block 209 upwards, which in turn drives the sleeve 207 upwards. The sleeve 207 then drives the round rod 206 upwards. That is, the round rod 206 and the corresponding pipe 6 expand, loosening the packing layer to ensure the flow of exhaust gas and thus ensure the exhaust gas purification effect. It should be understood that during the reciprocating rotation of the hollow rod 4 driven by the motor 203, the hollow rod 4 drives the sleeve 207 to reciprocate, causing the sleeve 207 to reciprocate within the connecting block 209. In use, the expansion movement of the round rod 206 and the corresponding pipe 6 loosens the packing layer, avoiding the problem of the packing layer becoming too compact after rinsing and interfering with the purification operation.

[0028] During the exhaust gas purification process, the cylinder 2010 and the connecting block 2011 work together to surround the motor 203 and the electric push rod 208, thereby intercepting the water vapor and impurities inside the cylinder 1 and achieving a protective effect. It should be understood that when the electric push rod 208 drives the sleeve 207 to move upward, the sleeve 207 drives the connecting block 2011 to slide upward inside the cylinder 2010. When the hollow rod 4 drives the sleeve 207 to rotate, the sleeve 207 rotates inside the connecting block 2011.

[0029] It also includes a netting 2012; each round rod 206 is fixedly connected to a corresponding pipe 6 with a netting 2012; the netting 2012 is elastic.

[0030] Before the next flush, the sleeve 207 should drive the round rod 206 downwards back to its original position so that the round rod 206 can loosen the packing again. However, if any packing is located in the gap between the pipe 6 and the round rod 206 during the downward movement of the round rod 206, the round rod 206 is very likely to crush the packing at this point during the resetting process. Therefore, an intercepting net 2012 is set between the pipe 6 and the round rod 206. When the round rod 206 moves upwards, it stretches the intercepting net 2012, causing it to unfold. When the round rod 206 resets, the intercepting net 2012 intercepts the packing, preventing it from moving into the gap between the round rod 206 and the pipe 6 and being crushed, thus achieving a protective function.

[0031] During regular stirring, the large contact area between the expanded interceptor mesh-2012 and the packing layer increases the disturbance area and force on the packing, which is beneficial to improving the stirring effect, making it easier to eliminate channeling, and further improving the exhaust gas purification effect. During use, the interceptor mesh-2012, which is used to protect the packing, also increases the shear area of ​​the stirring, which is beneficial to improving the stirring effect on the packing, making it easier to eliminate channeling, and further improving the exhaust gas purification effect.

[0032] Example 2, based on Example 1, such as Figure 2 and Figure 6 As shown, it also includes pipe 3 2013; four pipes 3 2013 are connected and fixed to the long pipe 5, and pipes 3 2013 pass through the hollow rod 4; a cavity 92 is formed between the hollow rod 4 and the baffle 3, and the cavity 92 is connected to pipe 3 2013; four channels 1 93 are opened on the baffle 3, and channels 1 93 are connected to the cavity 92; several channels 2 94 are opened on the baffle 3, and channels 2 94 are connected to the corresponding channels 1 93.

[0033] It also includes a second interception net 2014; the second interception net 2014 is fixedly connected to the inner side of the cylinder 1, and the packing is intercepted and limited by the second interception net 2014.

[0034] To prevent the bottommost pipe 6 from damaging the packing material during rotation, its position needs to be adjusted upwards to move it away from the baffle 3. This prevents pipe 6 from flushing the bottommost packing material. Therefore, pipe 3 2013 is installed. During flushing, the cleaning fluid in the long pipe 5 flows into the cavity 92 through pipe 3 2013, then flows into channel 1 93 from the cavity 92, and finally sprays upwards from channel 2 94. This cleaning fluid is used to flush the bottommost packing material. In use, the cavity 92, channel 1 93, and channel 2 94 are opened on the baffle 3, allowing the cleaning fluid to spray upwards from channel 2 94 to flush the packing material below, which improves the flushing effect.

[0035] A drying deodorization method includes the following steps: Step 1: Waste gas input and liquid spraying. The waste gas enters the cylindrical cylinder 1 through the square pipe 2, and the liquid is sprayed onto the packing layer above the baffle 3 through the pipe 201 and the nozzle 202. The waste gas passes through the packing layer and reacts with the liquid to achieve preliminary deodorization. Step 2: Stirring and optimizing distribution. Start motor 203 to drive hollow rod 4 to rotate, so that pipe 16 stirs the packing layer, eliminates the channeling of the medicine, and improves the purification effect of the exhaust gas. Step 3: Internal flushing and descaling. Stop the supply of air and chemicals, and introduce high-pressure cleaning fluid into long pipe 5. Flushing the packing layer upward through pipe 1 6, and simultaneously flushing the bottom packing through pipe 3 2013, cavity 92, channel 1 93 and channel 2 94. Step 4: Loosening and protecting the filler. The electric push rod 208 pushes the sleeve 207 and the round rod 206 to expand upward and loosen the filler layer. Step 5: Drainage and system reset. The waste liquid is discharged through the round hole of baffle 3 to the bottom of cylinder 1 and then discharged. The round rod 206 and the interceptor net 2012 are reset, and the system returns to standby state.
