Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, in particular to a spray tower for waste gas treatment. Background Art

[0002] With the acceleration of industrialization, the problem of air pollution is becoming increasingly serious. In particular, the large amount of waste gas generated during industrial production poses a threat to the environment and human health. In order to effectively control these waste gases, various waste gas treatment equipment have emerged. Among them, spray towers, as a highly efficient waste gas purification device, have been widely used in many industries. The basic working principle of the spray tower is to remove harmful substances in the waste gas by contacting the waste gas containing pollutants with the spray liquid and utilizing the mass transfer process between the gas and liquid phases. A packing layer is usually provided inside the spray tower. These packings provide a larger specific surface area to increase the chance of gas-liquid contact, thereby improving the waste gas purification efficiency. At the same time, the packing layer can also effectively disperse the gas flow, allowing it to pass through the entire tower more evenly, further improving the treatment effect.

[0003] Although the spray tower performs well in waste gas treatment, it also encounters some challenges in actual use, especially when maintenance is required after long-term operation. Due to the complex composition of the waste gas, after long-term operation, the packing layer in the spray tower will absorb a large amount of pollutants, causing it to become dirty. At this time, the packing layer in the spray tower needs to be replaced. However, due to the small observation port of the spray tower and the large tower body, it is difficult for personnel to directly enter the tower to perform operations. The current practice is to use auxiliary tools to remove the packing from the tower, but this method is inefficient and time-consuming, resulting in a significant increase in the time required to complete a packing replacement. This has an adverse impact on the normal production operations of the enterprise, increasing downtime and labor costs. Summary of the Invention

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example: A spray tower for waste gas treatment, see Figure 1-Figure 7As shown, it includes a spray tower 1, a filter plate 101, a pipe 102 and a spray head 103; the filter plate 101 is installed inside the spray tower 1, and the top of the filter plate 101 is used to place filler, and the filter plate 101 does not block the passage of exhaust gas in the spray tower 1; the spray tower 1 is provided with a pipe 102, which is used to transport the solution; the pipe 102 is installed with spray heads 103 at intervals, and the spray heads 103 are located inside the spray tower 1 and directly above the filter plate 101, and are used to spray the solution; a material hole 104 is opened on the right side of the spray tower 1;

[0031] It also includes a rotating mechanism, a connecting plate 3, a movable plate 4, a rubber plate 5, a pulling mechanism, a reset mechanism, a sliding frame 8, a collecting frame 9, a spiral feeder 10, a feeding pipe 11 and a shielding mechanism; a rotating mechanism is provided on the filter plate 101, and four connecting plates 3 are evenly spaced on the rotating mechanism. The rotating mechanism is used to drive the connecting plate 3 to rotate, and the distance between the bottom of the connecting plate 3 and the top of the filter plate 101 is less than the diameter of the filler (the filler is usually spherical).

The new filler is placed in the collecting frame 9, and the screw feeder 10 is used to transport the filler to the feeding pipe 11, so that the filler passes through the feeding pipe 11 and the material hole 104 and falls on the top of the filter plate 101, thereby completing the automatic feeding of the filler; a shielding mechanism is provided on the spray tower 1, which is used to shield the material hole 104 to prevent the exhaust gas from being discharged through the material hole 104.

[0032] See Figure 3 As shown, the rotating mechanism includes a first motor 201 and a connecting rod 202; the first motor 201 is installed in the middle of the bottom of the filter plate 101, and the connecting rod 202 is connected to the output shaft of the first motor 201. The connecting rod 202 rotates through the filter plate 101, and four connecting plates 3 are evenly spaced and connected to the connecting rod 202.

[0033] See Figure 4As shown, the pulling mechanism includes a second motor 601, a winding wheel 602 and a connecting rope 603; the second motor 601 is installed on the side of each of the four connecting plates 3; the winding wheel 602 is connected to the output shaft of the second motor 601; one end of the connecting rope 603 is connected to the winding wheel 602, and the other end of the connecting rope 603 is connected to the movable plate 4.

[0034] See Figure 4 and Figure 5 As shown, the reset mechanism includes a guide wheel 701 and an elastic rope 702; the guide wheel 701 is rotatably mounted on the connecting plate 3; one end of the elastic rope 702 is connected to the connecting plate 3, and the other end of the elastic rope 702 passes around the guide wheel 701 and is connected to the movable plate 4 on the adjacent connecting plate 3.

[0035] See Figure 7 As shown, the shielding mechanism includes a guide rod 1201, a baffle 1202 and an electric push rod 1203; two groups of guide rods 1201 are arranged on the right side of the spray tower 1, and the two groups of guide rods 1201 are distributed up and down, and the number of guide rods 1201 in one group is two; a baffle 1202 is slidingly arranged between the two guide rods 1201 of the same group, and the two baffles 1202 are distributed up and down, and both baffles 1202 are used to shield the material hole 104, the lower baffle 1202 shields the sliding frame 8, and the upper baffle 1202 shields the feeding pipe 11; two groups of electric push rods 1203 are also arranged on the right side of the spray tower 1, and the two groups of electric push rods 1203 are distributed up and down, and the number of one group of electric push rods 1203 is two; the telescopic rods of the two groups of electric push rods 1203 are respectively connected to the two baffles 1202.

[0036] Before use, first put an appropriate amount of filling material into the collecting frame 9, and then use the electric push rod 1203 to drive the upper baffle 1202 to move upward so that the upper baffle 1202 does not block the material hole 104 and the feeding tube 11, and then use the spiral feeder 10 to feed the filling material in the collecting frame 9 into the feeding tube 11, so that the filling material falls on the top of the filter plate 101 through the feeding tube 11 and the material hole 104, and the filling material is in the discharge space between the two connecting plates 3. After the discharge space is filled with an appropriate amount of filling material, the connecting plate 3 is driven by the first motor 201 to discharge the material. The rod 202 and the connecting plate 3 rotate 90 degrees, so that the connecting plate 3 drives the filling material on the top of the filter plate 101 to move, thereby adjusting the position of the filling material on the top of the filter plate 101 and causing the filling material fed into the subsequent feeding tube 11 to fall into another discharge space. This process is repeated until the four discharge spaces are filled with an appropriate amount of filling material. Then, the upper baffle 1202 is driven downward by the electric push rod 1203 to reset, so that the upper baffle 1202 again covers the material hole 104 and the feeding tube 11. In this way, the automatic feeding of the filling material is completed.

[0037] When it is used later, the solution is sent into the spray head 103 through the pipe 102, so that the spray head 103 sprays the solution on the filler, and then the exhaust gas is passed into the spray tower 1, so that the exhaust gas passes through the filter plate 101 from bottom to top and contacts the filler, so that the exhaust gas reacts with the solution on the surface of the filler, and then the harmful substances in the exhaust gas are removed, thereby achieving the purpose of exhaust gas purification;

[0038] Later, when the filling material in the spray tower 1 needs to be replaced, the first motor 201 drives the connecting rod 202 and the connecting plate 3 to rotate until the connecting plate 3 rotates to be flush with the rear edge of the material hole 104, so that the material hole 104 is aligned with the discharge space, and then the electric push rod 1203 drives the lower baffle 1202 to move downward so that the lower baffle 1202 does not block the material hole 104 and the sliding frame 8, and then the corresponding second motor 601 drives the winding wheel 602 to rotate, so that the winding wheel 602 reels the connecting rope 603, so that the connecting rope 603 pulls the movable plate 4 and the rubber plate 5 The movable plate 4 and the rubber plate 5 move toward the side close to the material hole 104, thereby pushing the filling material in the discharge space toward the material hole 104, so that the filling material passes through the material hole 104 and falls into the sliding frame 8, and then the filling material slides through the sliding frame 8 to the collecting frame 9 for collection. In this way, the filling material in the discharge space can be discharged. During this period, when the rubber plate 5 moves, the rubber plate 5 is squeezed by the inner wall of the spray tower 1, so that the rubber plate 5 will continue to deform. At the same time, the rubber plate 5 will pull the elastic rope 702 to a deformed state. When all the filling materials in the discharge space fall into the collecting frame 9 and are collected, the rubber plate 5 is discharged through the rubber plate 5. The corresponding second motor 601 drives the winding wheel 602 to reverse and reset, so that the winding wheel 602 unwinds the connecting rope 603, thereby loosening the connecting rope 603 from the movable plate 4 and the rubber plate 5. At this time, the elastic rope 702 returns to its original state, and the elastic rope 702 drives the movable plate 4 and the rubber plate 5 to move to the side away from the material hole 104 and reset. During this period, when the rubber plate 5 moves and resets, the rubber plate 5 will separate from the spray tower 1, so that the rubber plate 5 will return to its original state, and then the first motor 201 drives the connecting rod 202 and the connecting plate 3 to rotate until the next connecting plate 3 rotates to the back of the material hole 104 The edges are flush, so that the material hole 104 is aligned with the next discharge space, and then the above operation is repeated to discharge the filling material in the next discharge space until the filling material in all the discharge spaces is discharged. Then the electric push rod 1203 drives the lower baffle 1202 to move upward and reset, so that the lower baffle 1202 blocks the material hole 104 and the sliding frame 8 again, and then all the filling material in the collection frame 9 is taken out. In this way, the automatic unloading of the filling material can be completed, and then the above filling material loading operation is repeated to load the new filling material, thereby completing the replacement of the filling material.

[0039] See Figure 7-Figure 9As shown, it also includes a material shifting mechanism, which includes a connecting frame 13, a base 14, a shifting rod 15, a third motor 16 and a limiting clamp 17; four connecting frames 13 are installed at annular intervals on the outside of the spray tower 1, and a wavy hole 1301 is opened on the connecting frame 13; a base 14 is provided on the inside of the connecting frame 13, and two shifting rods 15 are connected to the base 14 through a spherical joint, and the shifting rods 15 pass through the wavy hole 1301, and the shifting rods 15 are located between the bottom of the connecting plate 3 and the top of the filter plate 101; two third motors 16 are installed on the top of the base 14, and the output shafts of the two third motors 16 are connected to the limiting clamps 17, and the two limiting clamps 17 respectively clamp the two shifting rods 15 connected to the base 14.

[0040] By setting up a material shifting mechanism, when the connecting plate 3 drives the filler on the top of the filter plate 101 to move, the filler will move over the shifting rod 15; when the four discharge spaces have all completed the automatic loading of the filler, the third motor 16 can drive the limit clamp 17 to intermittently rotate forward and reverse, so that the limit clamp 17 drives the shifting rod 15 to rotate forward and reverse intermittently, and the wavy hole 1301 is used to guide the shifting rod 15 so that the shifting rod 15 can swing back and forth at the same time. When the shifting rod 15 contacts the filler in the discharge space, the shifting rod 15 can shift the filler in the discharge space so that the filler in the discharge space is evenly arranged, thereby ensuring that the gas and liquid can fully contact in the spray tower 1.

[0041] See Figure 10 and Figure 11 As shown, it also includes a filtering mechanism, which includes a support plate 18, a water pump 1801, a first connecting pipe 19, a second connecting pipe 20, a three-way valve 21, a first filter 22 and a second filter 23; a support plate 18 is installed at the lower outer part of the spray tower 1; a water pump 1801 is installed on the top of the support plate 18, and the water outlet of the water pump 1801 is connected to the pipeline 102; the water inlet of the water pump 1801 is connected to the first connecting pipe 19; the lower outer part of the spray tower 1 is also connected to the second connecting pipe 20; the ends of the first connecting pipe 19 and the second connecting pipe 20 are both connected to the three-way valves 21, and the two three-way valves 21 are each provided with three ports, the first ports of the two three-way valves 21 are respectively connected to the first connecting pipe 19 and the second connecting pipe 20, the first filter 22 is connected between the second ports of the two three-way valves 21, and the second filter 23 is connected between the third ports of the two three-way valves 21. The first filter 22 and the second filter 23 are both used to filter the solution.

[0042] In the initial state, the two three-way valves 21 only form a passage with the first filter 22 or the second filter 23;

[0043] By setting up the filtering mechanism, when the solution passes through the filter plate 101 and falls to the bottom of the spray tower 1, the water pump 1801 can be used to pump the solution at the bottom of the spray tower 1 through the second connecting pipe 20 into the first filter 22 or the second filter 23, so that the solution passes through the first filter 22 or the second filter 23 for filtration, and then the filtered solution passes through the first connecting pipe 19 into the pipeline 102 for reuse, so that the solution can be recycled, thereby saving resources; when the first filter 22 or the second filter 23 needs to be repaired, if the first filter 22 needs to be repaired, the first filter 22 can be repaired. The two three-way valves 21 form a passage only with the second filter 23, and then the first filter 22 is removed for maintenance to enable the second filter 23 to work normally. If the second filter 23 needs to be repaired, the two three-way valves 21 form a passage only with the first filter 22, and then the second filter 23 is removed for maintenance to enable the first filter 22 to work normally. In this way, when one of them is repaired, the other one can work normally, and the filtration of the solution will not be affected by the maintenance. After the first filter 22 or the second filter 23 is repaired, the first filter 22 or the second filter 23 is installed back to its original position.

[0044] See Figure 12 As shown, it also includes an anti-blocking mechanism, which includes a connecting ring 24, a shielding cover 25 and a spring 26; a connecting ring 24 is installed on the lower outer side of the sprinkler head 103; a shielding cover 25 is slidably provided at the bottom of the connecting ring 24, and the shielding cover 25 is used to cover the water outlet of the sprinkler head 103; a spring 26 is connected between the bottom of the connecting ring 24 and the shielding cover 25.

[0045] By providing an anti-blocking mechanism, when the spray head 103 is spraying the solution, the solution will squeeze the shielding cover 25 downward through the water outlet of the spray head 103, causing the shielding cover 25 to move downward and the spring 26 to stretch, so that the shielding cover 25 no longer covers the water outlet of the spray head 103; when the spray head 103 completes spraying the solution, the spring 26 returns to its original state, and the spring 26 drives the shielding cover 25 to move upward and reset, so that the shielding cover 25 can scrape off the dirt attached to the surface of the water outlet of the spray head 103, thereby preventing the water outlet of the spray head 103 from being blocked due to long-term adhesion of dirt. At the same time, the shielding cover 25 can also cover the water outlet of the spray head 103 to prevent the water outlet of the spray head 103 from being blocked by foreign matter when it is not working.
