Description

Technical Field

[0001] The invention relates to the technical field of lightness removal towers, in particular to a low-energy consumption and energy-saving chemical lightness removal tower. Background Art

[0002] The de-lightness tower is a mass transfer device that uses the filler in the tower as a contact member between the gas and liquid phases. The tower body of the de-lightness tower is a vertical cylinder with a filler support plate at the bottom. The filler is placed on the support plate in a random or neat manner. A filler pressure plate is installed above the filler to prevent it from being blown by the rising airflow. The liquid is sprayed onto the filler from the top of the tower through the liquid distributor and flows down along the surface of the filler. The gas is sent in from the bottom of the tower and distributed by the gas distribution device (small-diameter towers generally do not have a gas distribution device). It passes through the gaps in the filler layer in a countercurrent with the liquid. On the surface of the filler, the gas and liquid are in close contact for mass transfer. Most traditional de-lightness towers require the addition of corresponding absorption liquid. The absorption liquid is mixed with water and reaction liquid and then enters the de-lightness tower. However, most of the existing absorption liquids are manually added at intervals and the concentration is fixed. When the gas flow or concentration increases, the content of the absorption liquid will increase accordingly, and manual addition is difficult to ensure the accuracy and continuity of the addition of the absorption liquid.

[0003] The existing patent (Announcement No.: CN111921359A) is a low-energy consumption and energy-saving chemical de-lightening tower, which includes a de-lightening tower body, an operating mechanism, a feeding mechanism, a water inlet pipe, a through pipe, a slider, a connecting rod, a feeding mechanism, a feeding pipe, a storage cylinder, a water stop valve, a plug, a third spring and a through hole. The user of the present invention can connect the through pipe thread to the inner wall of the water inlet pipe, and the end of the through pipe gradually squeezes and resists the slider. When the slider is squeezed and resisted, the slider moves, and the movement of the slider drives the plug to move, and the third spring is compressed accordingly. When the through hole is completely moved out of the feeding pipe, the absorption liquid stored in the storage cylinder will flow into the feeding pipe, and then enter the interior of the de-lightening tower body through the through hole inside the plug.

[0004] Although the above patent can avoid manual adjustment, is more convenient to use, and ensures the accuracy and continuity of adding the absorption liquid, it still has some shortcomings:

[0005] 1. This low-energy-consumption and energy-saving chemical light-removing tower drives the slider to move through the impact of water inside the water inlet pipe, and the sliders collide to cause the sliders to move, and the movement of the sliders drives the plug. Once the water pressure impact force is uneven during water injection, this mechanism is likely to cause the piston to deform and tilt, which in turn causes the pipe to be blocked, and the piston cannot move, and the entire mechanism cannot be used normally. In addition, the movement of the second sealing block cannot cause the water inlet pipe to be completely closed, and the water flows out along the connecting rod. Long-term use will cause the rod body to rust and water to drip, and the use effect is poor;

[0006] 2. This low-energy and energy-saving chemical light-removal tower only solves the accuracy and continuity of the addition of the absorption liquid. However, during the tower reaction, when the raw materials are stacked on the packing plate, the tower is heated by gas and the reaction liquid and absorption liquid are added to make the raw materials react, thereby producing a gas phase and a liquid phase. However, when the liquid sprayed on the top of the tower body is left too fast, the gas heating and reaction time will be shortened, which will cause insufficient reaction of the raw materials and affect the reaction rate. In addition, when the tower body is used to extract the reactants, especially for substances such as tar, the viscosity of the liquid after the reaction is relatively large. When the liquid after the reaction flows downward through the leakage holes of the packing plate, it is very easy to adhere to the inside of the leakage holes. After the tower body is used up, the temperature in the tower drops, and the liquid reactants attached to the inside of the hole grooves condense into a solid state, which is very easy to cause the leakage holes to be blocked, thereby affecting the later liquid discharge, and at the same time, affecting the rise and reaction of hot gas.

[0007] Therefore, a low-energy consumption and energy-saving chemical light-removal tower is proposed. Summary of the invention

[0033] The feeding assembly 5 includes a feeding pipe 51, a water pipe 52, a storage box 53, a rotating ball 54, a rotating rod 55, a toothed disc 56 and a discharge pipe 57. The feeding pipe 51 is fixedly installed at the lower end of the feed pipe 41, and half of the tube body of the feeding pipe 51 penetrates into the interior of the tower body 1. The storage box 53 is fixedly installed at the right side of the feeding pipe 51 through the water pipe 52, and the left and right end pipe openings of the water pipe 52 are respectively connected to the feeding pipe 51 and the storage box 53. The rotating ball 54 is rotatably connected to the interior of the feeding pipe 51, and the rotating rod 55 is fixedly installed at the upper end of the rotating ball 54. The rotating rod 55 passes through the upper end of the feeding pipe 51 and extends to the inside of the transverse groove 411. The toothed disc 56 is fixedly installed on the upper end of the rotating rod 55, and a plurality of second tooth blocks 561 are fixedly installed at equal distances on the outer surface of the toothed disc 56. The toothed disc 56 is located near the left side of the front end outer surface of the bottom plate 45, and the first tooth block 451 is meshed with the second tooth block 561. A hollow hole 541 is provided on the outer surface of the rotating ball 54 near the rear end one-third. The discharge pipe 2 57 is fixedly installed on the left side of the feeding pipe 51, and the pipe mouth of the discharge pipe 2 57 is offset from the pipe mouth of the discharge pipe 1 46.

[0034] During operation, the material to be extracted is first poured into the tower body 1 from the feed port 13 and stacked on the packing plate 3. Hot gas is input through the gas phase inlet 12 to heat the inside of the tower body 1. While the material is being heated, the pressure pump 43 is started. The pressure pump 43 brings the reaction liquid into the feed pipe 41 through the water pipe 42. When the flow rate or concentration of the gas increases, the pressure in the feed pipe 41 needs to be increased. When the reaction liquid and pressure in the water pipe 42 and the feed pipe 41 reach a certain amount, the water flow in the feed pipe 41 impacts the inner pipe plug 44, and drives the inner pipe plug 44 in the feed pipe 41. As the inner tube plug 44 moves from right to left, the spring 441 stretches, and a portion of the reaction liquid first enters the left side of the feed pipe 41 through the notch of the rectangular groove 442, and then flows into the tower along the discharge pipe 46. When the inner tube plug 44 is impacted by the water flow and moves to the left, the bottom plate 45 at its lower end moves to the left accordingly, and the bottom plate 45 gradually overlaps with the transverse groove 411, and the transverse groove 411 is closed. During the movement of the bottom plate 45, the first tooth block 451 on the outer surface of the front end thereof meshes with the second tooth block 561 in a counterclockwise manner, which can drive the toothed disc 56 to rotate, and at the same time, the rotating ball 54 rotates counterclockwise, rotating the hollow hole 541 of the rotating ball 54 to the When the inner wall of the rear end of the feeding pipe 51 is in contact with the inner wall, the absorption liquid in the storage box 53 flows into the feeding pipe 51 along the water pipe 52, and then is discharged to the inside of the discharge pipe 57 along the hollow hole 541. The deflection angle of the hollow hole 541 of the rotating ball 54 increases, the exposed area of ​​the hollow hole 541 gradually increases, and the shielding area gradually decreases, so that the amount of absorption liquid discharged through the hollow hole 541 will also increase, and the discharged absorption liquid will then be poured into the inside of the tower body 1 through the discharge pipe 57; on the contrary, when the discharge of the reaction liquid from the feeding pipe 41 decreases, the internal pressure of the feeding pipe 41 decreases, so that the feeding The amount of liquid discharged from the tube 41 and the amount of absorption liquid discharged from the feeding tube 51 also decrease accordingly. When the flow rate of water in the feeding tube 41 decreases and the pressure is relatively low, the inner tube plug 44 is reset under the action of the spring 441. The inner tube plug 44 pushes back to drive the bottom plate 45 to move to the right. At this time, the first tooth block 451 and the second tooth block 561 rotate clockwise, the rotating ball 54 is reset, the hollow hole 541 rotates back to its original position, the feeding tube 51 is closed and the feeding is stopped, thereby realizing the automatic addition of absorbent and reactant in the delightening tower, reducing manual adjustment, and at the same time ensuring the accurate measurement and continuity of absorbent addition, thereby improving work efficiency.

[0035] As an embodiment of the present invention, Figure 4 and Figure 5 As shown, the inner tube plug 44 is made of metal, and its diameter matches the inner diameter of the feed tube 41 , the length of the transverse groove 411 is greater than the length of the bottom plate 45 , and the cross-section of the upper end plate of the bottom plate 45 matches the notch of the transverse groove 411 .

[0036] During operation, the inner tube plug 44 moves under the pressure impact of the reaction liquid, and the bottom plate 45 fixedly connected to its bottom can maintain the horizontal movement of the inner tube plug 44, thereby reducing the tilting of the inner tube plug 44 caused by the uneven impact force of the water flow inside the feed pipe 41. The setting of the length of the transverse groove 411 and the bottom plate 45 can enable the inner tube plug 44 to move horizontally, prompting the bottom plate 45 to move horizontally inside the transverse groove 411. At the same time, the transverse groove 411 can be sealed by utilizing the structure of the bottom plate 45 itself, thereby reducing the dripping of the reaction liquid to the outside or flowing into the inside of the feeding pipe 51.

[0037] As an embodiment of the present invention, Figure 4 and Figure 6 As shown, the rotating ball 54 is made of stainless steel metal, the diameter of the rotating ball 54 matches the inner diameter of the feeding tube 51 , and the lower end center axis point of the rotating ball 54 is embedded in the inner surface of the feeding tube 51 near the lower end.

[0038] During operation, when the second tooth block 561 on the toothed disc 56 rotates with the first tooth block 451, the rotating ball 54 rotates with the toothed disc 56, and the lower end of the rotating ball 54 rotates in a circle with the embedded groove as the center. The absorption liquid controls the amount of absorbent discharged through the deflection angle of the hollow hole 541 on the rotating ball 54. When the liquid addition inside the tower body 1 stops, the rotating ball 54 rotates accordingly, and the hollow hole 541 rotates back to its original position. At this time, the hollow hole 541 is located on the right side of the rotating ball 54, and the right side of the rotating ball 54 is in a closed state, and the feeding pipe 51 is also in a closed state.

[0039] As an embodiment of the present invention, Figure 3 and Figure 5 As shown, a plurality of the first tooth blocks 451 are horizontally and equidistantly distributed, and the distance between two adjacent first tooth blocks 451 is 2 cm to 3 cm.

[0040] During operation, the toothed disc 56 is rotatably connected to the first tooth block 451, and the first tooth block 451 is meshed with the second tooth block 561. When the distance between two adjacent first tooth blocks 451 increases, the rotation frequency of the toothed disc 56 is reduced, thereby slowing down the situation where the ball 54 rotates too fast and causes the amount of absorbed liquid discharged to be too large or too small, and its uniform rotation can be maintained.

[0041] As an embodiment of the present invention, Figure 7 As shown, a circular groove 6 is provided inside the filler plate 3, and an inner circular plate 61 is rotatably connected inside the circular groove 6, a rotating shaft 62 is fixedly installed at the center position of the outer surface of the lower end of the inner circular plate 61, and the rotating shaft 62 extends through and extends to the lower end of the tower body 1 and is fixedly installed with a motor 63, and a plurality of groups of hole grooves 64 are also provided in an annular shape from the center to the outside on the upper end outer surface of the inner circular plate 61, and the hole grooves 64 correspond to the hole grooves 31 up and down and are connected.

[0042] During operation, by arranging an inner circular plate 61 inside the filler plate 3, the motor 63 drives the inner circular plate 61 to rotate, and the short misalignment of the hole groove 2 64 and the hole groove 1 31 can keep the hot air rising to the upper end of the filler plate 3 warm, thereby extending the heating time of the substance, and at the same time enhancing the reaction effect of the gas and liquid and improving the reaction rate.

[0043] As an embodiment of the present invention, Figure 7 As shown, the diameter of the inner circular plate 61 is consistent with the inner diameter of the circular groove 6, and the upper and lower outer surfaces of the inner circular plate 61 and the inner surface of the circular groove 6 are respectively separated by a distance of 0.5 mm to 1 cm near the upper and lower ends. The upper and lower outer surfaces of the inner circular plate 61 and the inner surface of the circular groove 6 are both embedded with protrusions 7, and several of the protrusions 7 are grouped in pairs. A group of protrusions 7 is respectively fixedly installed between two adjacent hole grooves 64 on the left and right, and the protrusions 7 on the circular groove 6 and the protrusions 7 on the inner circular plate 61 are placed in an upper and lower offset manner.

[0044] During operation, the motor 63 drives the rotating shaft 62, and the inner circular plate 61 also rotates accordingly. During the rotation process, the convex points 7 on the outer surfaces of the upper and lower ends of the inner circular plate 61 and the convex points 7 inside the circular groove 6 move relative to each other and collide with each other. During the collision between the two, the inner circular plate 61 and the filling plate 3 both vibrate, and the inside of the hole groove 1 31 and the hole groove 2 64 are hit, and the liquid raw materials accumulated in the two also fall into the inside of the tower body 1 through the mutual collision of the convex points 7, thereby keeping the internal holes of the filling plate 3 smooth, reducing material blockage, and increasing the rate of material infiltration, while facilitating the rise of gas and the heating of materials.

[0045] Working principle: When working, first pour the material to be extracted into the tower body 1 from the feed port 13 and stack it on the packing plate 3. Input hot gas through the gas phase inlet 12 to heat the inside of the tower body 1. While the material is being heated, start the pressure pump 43. The pressure pump 43 brings the reaction liquid into the inside of the feed pipe 41 through the water pipe 42. When the flow rate or concentration of the gas increases, the pressure in the feed pipe 41 needs to be increased. When the reaction liquid and pressure in the water pipe 42 and the feed pipe 41 reach a certain amount, the water flow in the feed pipe 41 impacts the inner pipe plug 44 and drives the inner pipe plug 44 to move from right to left in the feed pipe 41. The spring 441 is stretched, and a part of the reaction liquid first enters the left side of the feed pipe 41 through the notch of the rectangular groove 442. When the inner pipe plug 44 is impacted by the water flow and moves to the left, the bottom plate 45 at its lower end moves to the left accordingly, and the bottom plate 45 gradually overlaps with the transverse groove 411, and the transverse groove 411 is closed. During the movement of the bottom plate 45, the first tooth block 451 and the second tooth block 561 on the outer surface of the front end thereof mesh with each other in a counterclockwise manner, which can drive the toothed disc 56 to rotate. At the same time, the rotating ball 54 rotates counterclockwise, and when the hollow hole 541 of the rotating ball 54 is rotated to be in contact with the rear end inner wall of the feeding pipe 51, the absorption liquid in the storage box 53 flows into the inside of the feeding pipe 51 along the water pipe 2 52, and then discharges the absorption liquid into the inside of the discharge pipe 2 57 along the hollow hole 541. The deflection angle of the hollow hole 541 of the rotating ball 54 increases, and the hollow hole 5 The exposed area of ​​41 gradually increases, and the shielded area gradually decreases, so that the amount of absorption liquid discharged through the hollow hole 541 will also increase, and the discharged absorption liquid will then be poured into the interior of the tower body 1 through the discharge pipe 2 57; on the contrary, when the discharge of the reaction liquid from the feed pipe 41 decreases, the internal pressure of the feed pipe 41 decreases, so that the discharge amount inside the feed pipe 41 and the amount of absorption liquid discharged from the feeding pipe 51 also decrease accordingly, until the flow of water inside the feed pipe 41 decreases and the pressure is small, the inner pipe plug 44 is reset under the action of the spring 441, and the inner pipe plug 44 pushes back to drive the bottom plate 45 to move to the right. At this time, the first tooth block 451 and the second tooth block 561 rotate clockwise, the rotating ball 54 is reset, the hollow hole 541 rotates back to its original position, the feeding pipe 51 is closed and the feeding is stopped. The motor 63 drives the inner circular plate 61 to rotate, and the hole groove 64 and the hole groove 1 31 are temporarily misaligned, so that the hot air rising to the upper end of the filling plate 3 can be kept warm, thereby enhancing the reaction effect of the gas and the liquid. At the same time, when the motor 63 drives the rotating shaft 62, the inner circular plate 61 also rotates accordingly. During its rotation, the convex points 7 on the outer surfaces of the upper and lower ends of the inner circular plate 61 and the convex points 7 inside the circular groove 6 move relative to each other and collide with each other. During the collision between the two, the inner circular plate 61 and the filling plate 3 both vibrate, and the inside of the hole groove 1 31 and the hole groove 2 64 are hit, and the liquid raw materials accumulated in the two also fall into the inside of the tower body 1 through the mutual collision of the convex points 7, thereby keeping the internal holes of the filling plate 3 smooth and reducing material blockage.
