Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and 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, especially the large amount of waste gas generated in the industrial production process, which 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, the spray tower, as a high-efficiency waste gas purification device, has 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 arranged inside the spray tower. These packings provide a large 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 exhaust gas treatment, it has also encountered some challenges in actual use, especially when maintenance is required after long-term operation. Due to the complex composition of the exhaust 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, which has an adverse impact on the normal production operations of the enterprise and increases downtime and labor costs. Summary of the invention

[0034] See also 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, 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 slidably arranged between the two guide rods 1201 of the same group, the two baffles 1202 are distributed up and down, and the two 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, the two groups of electric push rods 1203 are distributed up and down, and the number of electric push rods 1203 in one group is two; the telescopic rods of the two groups of electric push rods 1203 are respectively connected to the two baffles 1202.

[0035] Before use, first load an appropriate amount of filler into the collecting frame 9, then drive the upper baffle 1202 to move upwards through the electric push rod 1203, 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 filler in the collecting frame 9 into the feeding tube 11, so that the filler falls on the top of the filter plate 101 through the feeding tube 11 and the material hole 104, and the filler is placed in the discharge space between the two connecting plates 3. After a proper amount of filler is loaded into the discharge space, the first motor 201 drives the connecting plate 3 to discharge the filler. 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, so as to adjust the position of the filling material on the top of the filter plate 101, and make the filling material fed into the subsequent feeding tube 11 fall into another discharge space, and so on and so forth, until the four discharge spaces are filled with appropriate amounts of filling material, and then the upper baffle 1202 is driven by the electric push rod 1203 to move downward and reset, so that the upper baffle 1202 again covers the material hole 104 and the feeding tube 11, so that the automatic feeding of the filling material can be completed; 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 contacts the filler after passing through the filter plate 101 from bottom to top, 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, so as to achieve the purpose of exhaust gas purification; 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 material 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, so that the movable plate 4 and the rubber plate 5 push 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 be deformed. When all the filling materials in the discharge space fall into the collecting frame 9 and are collected, they are discharged again through the sliding frame 8. 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, so that the connecting rope 603 loosens 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 and reset to the side away from the material hole 104. 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, and then the lower baffle 1202 is driven by the electric push rod 1203 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, so that 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.

[0036] See also 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 arranged 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.

[0037] By setting up a material shifting mechanism, when the connecting plate 3 drives the filling material on the top of the filter plate 101 to move, the filling material will move over the shifting rod 15; when the four discharge spaces have all completed the automatic loading of the filling material, 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 intermittently rotate forward and reverse, 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 filling material in the discharge space, the shifting rod 15 can shift the filling material in the discharge space so that the filling material in the discharge space is evenly arranged to ensure that the gas and liquid can fully contact in the spray tower 1.

[0038] See also Fig.10 and Fig.11 As shown, a filtering mechanism is also included, 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 valve 21, and the two three-way valves 21 are both 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, and the first filter 22 and the second filter 23 are both used to filter the solution.

[0039] In the initial state, the two three-way valves 21 only form a passage with the first filter 22 or the second filter 23; 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 only form a passage with the second filter 23, and then the first filter 22 is removed for maintenance to make the second filter 23 work normally. If the second filter 23 needs to be repaired, the two three-way valves 21 only form a passage with the first filter 22, and then the second filter 23 is removed for maintenance to make the first filter 22 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.

[0041] 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, so that the shielding cover 25 moves downward, and the spring 26 is stretched, 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 attachment 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 objects when not working.
