Description

Technical Field

[0001] The invention relates to the technical field of nozzles and discloses an anti-clogging atomizing nozzle for a desulfurization tower. Background Art

[0002] Coke oven gas contains a large amount of sulfur compounds, which are harmful to human health and the environment. Therefore, desulfurization refers to one of the important processes for coke oven gas purification. At present, the most common and economical way to desulfurize coke oven gas is by spraying. In the process of flue gas passing through the desulfurization tower, it fully contacts and reacts with the spray liquid to achieve desulfurization. The spray liquid is generally a desulfurizer such as lime water. During the use of lime water, the lime cannot be completely dissolved in the water due to insufficient stirring, resulting in the concentration of lime water being lower than the normal level, affecting the desulfurization efficiency. The existing nozzle only plays an atomization role when used, and cannot crush the particles that have passed and not completely dissolved and integrate them into the spray liquid, resulting in the spray liquid desulfurization efficiency cannot be maximized, affecting the desulfurization efficiency of the flue gas. Summary of the invention

[0003] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides an anti-clogging atomizing nozzle for a desulfurization tower.

[0004] Technical solution: A blockage-proof atomizing nozzle for a desulfurization tower comprises a shell, a separator plate is fixedly connected inside the shell, the separator plate is provided with evenly distributed through holes, the separator plate is rotatably connected to a rotating shaft passing through the separator plate, a rolling blade is fixedly connected to the upper side of the rotating shaft, the distance between the rolling blade and the separator plate is smaller than the diameter of the through hole on the separator plate, the rolling blade is composed of circumferentially evenly distributed arc plates, the lower side of the rotating shaft is fixedly connected to circumferentially evenly distributed power blades, the power blades are inclined, the inclination direction of the power blades corresponds to the rotation direction of the rolling blades, and evenly distributed crushing protrusions are provided in the shell.

[0006] It is further explained that evenly distributed first guide strips are arranged on the upper side of the power blades, and the first guide strips are used to guide the lime water.

[0007] It is further explained that the inclination angle of the evenly distributed first guide strips changes gradually to disperse the lime water.

[0008] It is further explained that the portion of the shell located below the separation plate is provided with second guide strips evenly distributed in the circumferential direction, and the second guide strips are used to cause the lime water to rotate.

[0009] It is further explained that a reduced diameter portion is provided on the lower side of the shell to increase the flow rate of the lime water when leaving the shell.

[0010] Further description, it also includes gates that are evenly distributed in the circumference, the rolling blades are made of elastic material, the gates that are evenly distributed in the circumference are all hinged to the shell, the shell is provided with through holes that are evenly distributed in the circumference, the gates block adjacent through holes on the shell, the shell is slidably connected with sliding blocks that are evenly distributed in the circumference, the sliding block is rotatably connected with a rotating plate on the side away from the adjacent gate, the rotating plate is extruded and fitted with the rolling blades, a torsion spring is provided between the rotating plate and the adjacent sliding block, a thin rope is provided between the rotating plate and the adjacent gate, and the thin rope passes through the shell and the adjacent sliding block.

[0011] It is further explained that a symmetrically distributed limit plate is provided on one side of the sliding block close to the adjacent rotating plate, and a limit protrusion is provided on the opposite side of the symmetrically distributed limit plate. The symmetrically distributed limit plates are limitedly matched with the adjacent rotating plate, and the limit plates are elastic.

[0013] It is further explained that a filter screen is arranged on the outer side of the shell, and the filter screen is used to collect impurities.

[0014] The beneficial effects of the present invention are as follows: the present invention drives the incompletely dissolved particles to the periphery of the shell through the rotation of the rolling blades, and then the rolling blades cooperate with the adjacent crushing protrusions to crush the incompletely dissolved particles, so that the crushed particles are dissolved in the lime water and react with the flue gas, thereby improving the desulfurization efficiency of the desulfurization tower and preventing the incompletely dissolved particles from clogging the through holes of the separation disk.

[0015] By setting inclined power blades, the lime water provides power for the rotation of the rolling blades, and after the lime water hits the power blades, it will disintegrate to form a liquid with a smaller diameter, so as to improve the desulfurization efficiency of the desulfurization tower.

DETAILED DESCRIPTION

[0021] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0022] The nozzles used in existing desulfurization towers are unable to crush particles that are not completely dissolved in the spray liquid, resulting in the inability to maximize the desulfurization efficiency of the spray liquid, affecting the desulfurization efficiency of the flue gas.

[0023] Example 1: An anti-clogging atomizing nozzle for a desulfurization tower, combined with Figure 1 and Figure 2As shown, it includes a shell 1, a separation plate 2 is fixedly connected to the shell 1, and the separation plate 2 is provided with evenly distributed through holes, so that the undissolved particles are left on the upper side of the separation plate 2 for crushing, and the lime water reaches the lower side of the separation plate 2 through the through holes on the separation plate 2. The middle part of the separation plate 2 is rotatably connected with a rotating shaft 3 that passes through it, and a rolling blade 4 is fixedly connected to the upper side of the rotating shaft 3. The rolling blade 4 is made of elastic material. When the rolling blade 4 encounters undissolved particles, it can crush them. When encountering hard particle impurities that cannot be crushed, the rolling blade 4 is squeezed and deformed and bent, and the distance between the rolling blade 4 and the separation plate 2 is smaller than the diameter of the through holes on the separation plate 2, so that the undissolved particles with too large diameters are driven to the inner edge of the shell 1 by the rolling blade 4 for crushing. The rolling blade 4 is located on the upper side of the separation plate 2, and the rolling blade 4 is composed of three arc plates evenly distributed circumferentially. When the rolling blade 4 rotates clockwise, the undissolved particles are driven to the surroundings of the shell 1 for crushing. Rolling, six circumferentially evenly distributed power blades 5 are fixedly connected to the lower side of the rotating shaft 3, and the power blades 5 are located below the shell 1, and are used to disperse the lime water sprayed from the shell 1 to prevent the power blades 5 from affecting the lime water sprayed from the shell 1. The power blades 5 are tilted, and the tilt direction of the power blades 5 corresponds to the rotation direction of the rolling blades 4. When the lime water rushes towards the power blades 5, the power blades 5 drive the rolling blades 4 to rotate clockwise from the top view. Evenly distributed crushing protrusions 6 are arranged in the shell 1, and the rolling blades 4 and the crushing protrusions 6 are matched in concentric circles, that is, the outermost circle of the rolling blades 4 is smaller than the innermost circle of the crushing protrusions 6, thereby ensuring the stable rotation of the rolling blades 4. When the undissolved particles reach between the rolling blades 4 and the shell 1, the rolling blades 4 push the undissolved particles to move, and when the undissolved particles encounter the crushing protrusions 6, the undissolved particles are blocked by the crushing protrusions 6, and the rolling blades 4 continue to rotate to crush the undissolved particles.

[0024] Combination Figure 1 and Figure 2 As shown, four evenly distributed first guide bars 7 are provided on the upper side of the power blade 5. The first guide bars 7 are used to guide the lime water so that the lime water flowing straight downward is dispersed. The inclination angles of the four first guide bars 7 on the same power blade 5 gradually change, so as to evenly disperse the lime water, thereby improving the desulfurization efficiency of the lime water.

[0025] Combination Figure 1 and Figure 2As shown, the portion of the shell 1 located at the lower side of the separation plate 2 is provided with a second guide strip 8 evenly distributed in the circumferential direction. The second guide strip 8 is used to cause the lime water to rotate, so that the lime water has a certain centrifugal force when it is sprayed from the lower side of the shell 1, and then the lime water is dispersed to the surroundings when it is sprayed from the lower side of the shell 1. A reduced diameter portion is provided on the lower side of the shell 1 to increase the flow rate of the lime water when it leaves the shell 1. The faster the lime water is sprayed from the shell 1, the larger the range of dispersion is, thereby improving the desulfurization efficiency. In addition, the lime water is sprayed from the shell 1 at a fast speed, which can provide stronger power for the power blades 5.

[0026] When using the device, first install the device in the desulfurization tower. When the device is working, the lime water enters from the upper side of the shell 1, and then passes through the through hole on the separation plate 2 to reach the lower side of the shell 1. At this time, under the guiding effect of the six second guide strips 8 in the shell 1, the lime water rotates clockwise from the top view. When the lime water reaches the reduced diameter of the shell 1, the flow rate of the lime water increases. After the lime water passes through the reduced diameter of the shell 1, because the lime water is in a rotating state, part of the lime water is dispersed to the surroundings under the action of centrifugal force. The lime water in the middle rushes to the six power blades 5, thereby driving the power blades 5 to rotate clockwise from the top view. After the lime water rushes to the power blades 5, part of the liquid The droplets are broken into liquids with a smaller diameter due to impact with the power blades 5, thereby increasing the contact area between the lime water and the flue gas. The flow direction of the droplets and the lime water changes under the guidance of the adjacent first guide strip 7, thereby forming a uniformly distributed divergent shape, thereby increasing the contact area between the lime water and the flue gas. When the power blades 5 rotate, they drive the rotating shaft 3 to rotate, and the rotating shaft 3 drives the rolling blades 4 to rotate. The rolling blades 4 rotate clockwise to stir the lime water on the upper side of the separation disk 2, so that the particles that are not completely dissolved in the lime water are distributed to the surroundings under the action of centrifugal force, and then the rolling blades 4 and the adjacent crushing protrusions 6 cooperate to crush the incompletely dissolved particles, so that the particles are dissolved in the lime water, thereby improving the desulfurization efficiency.

[0027] The nozzles used in the existing desulfurization towers are unable to remove the hard granular impurities contained in the spray liquid. The hard granular impurities circulate along with the spray liquid under the action of the pump body, which may cause damage to the pump body and other devices.

[0028] Example 2: Based on Example 1, Figure 1 and Figure 3-Figure 5As shown, it also includes three gates 9 evenly distributed in the circumference. When the rolling blade 4 is deformed, elastic force is generated, so that the adjacent gates 9 are opened. The three gates 9 are hinged to the shell 1. The shell 1 is provided with three through holes evenly distributed in the circumference. The through holes are used to discharge hard particle impurities in the lime water. The gates 9 block the adjacent through holes on the shell 1. The shell 1 is slidably connected to three sliding blocks 10 evenly distributed in the circumference. The sliding block 10 is rotatably connected to a rotating plate 11 on the side away from the adjacent gate 9. The rotating plate 11 is rotated to The plate 11 is squeezed and matched with the rolling blade 4, and the rolling blade 4 moves to contact the rotating plate 11 and drives the rotating plate 11 to move. The rotating plate 11 is used to make the rolling blade 4 drive the adjacent sliding block 10 to reset. A torsion spring is arranged between the rotating plate 11 and the adjacent sliding block 10, and the torsion spring is used to reset the adjacent rotating plate 11. A thin rope is arranged between the rotating plate 11 and the adjacent gate 9, and the thin rope is used to transmit between the rotating plate 11 and the adjacent gate 9. The thin rope passes through the shell 1 and the adjacent sliding block 10.

[0029] Combination Figure 5 As shown, two limit plates 12 symmetrically distributed up and down are provided on one side of the sliding block 10 close to the adjacent rotating plate 11, and limiting protrusions are provided on the opposite sides of the two limit plates 12, which are horizontally placed triangular prisms, and the length of the side of the triangular face of the limit protrusion close to the adjacent sliding block 10 is less than the length of the side away from the adjacent sliding block 10, so that the rotating plate 11 needs to overcome greater resistance when resetting, to ensure that the adjacent gates 9 can be reset normally, and the two limit plates 12 are both limited and cooperated with the adjacent rotating plates 11, and the limit plates 12 are elastic. When the rotating plate 11 is pulled by the adjacent thin rope, the rotating plate 11 rotates, and the rotating plate 11 squeezes the long sides of the limiting protrusions on the adjacent limiting plates 12, and the adjacent limiting plates 12 are deformed. When the rotating plate 11 passes over the limiting protrusions on the adjacent limiting plates 12, the adjacent limiting plates 12 are reset and limit the rotating plate 11.

[0030] Combination Figure 6 As shown, the shell 1 is slidably connected with six limit columns 13 which are symmetrical up and down and evenly distributed circumferentially. A spring is arranged between the six limit columns 13 and the shell 1. The spring is used to limit the adjacent limit columns 13 to the adjacent gates 9. The two symmetrically distributed limit columns 13 are both limited and cooperated with the adjacent gates 9.

[0031] Combination Figure 1 As shown, a filter screen 14 is arranged on the outside of the shell 1, and the filter screen 14 is used to collect impurities. The particulate impurities discharged from the through hole of the shell 1 enter the filter screen 14, thereby preventing the particulate impurities from entering the circulation of lime water after being discharged from the shell 1.

[0032] When the lime water contains granular impurities with relatively high hardness, when the granular impurities reach the edge position inside the shell 1 and contact the rolling blade 4, the rolling blade 4 is deformed and squeezes the granular impurities. As the rolling blade 4 rotates, the granular impurities roll between the rolling blade 4 and the shell 1. When the granular impurities contact the gate 9, the elastic force generated by the deformation of the rolling blade 4 acts on the adjacent gate 9 through the granular impurities. The gate 9 rotates under the action of the lime water pressure and the elastic force of the rolling blade 4. When the gate 9 rotates, it squeezes the two adjacent limit posts 13. The two symmetrically distributed limit posts 13 are squeezed and move in opposite directions and compress the adjacent springs respectively. When the limit posts 13 are separated from the adjacent gate 9, the gate 9 is opened under the impact of the lime water pressure. At this time, the lime water carrying the granular impurities is discharged from the adjacent through holes on the shell 1, and the granular impurities fall into the filter 14, thereby preventing the granular impurities from entering the lime water circulation system again, thereby reducing the probability of damage to the pump body.

[0033] In the process of opening the gate 9 to discharge the particulate impurities, the gate 9 pulls the adjacent thin ropes, and the thin ropes pull the adjacent rotating plates 11 to drive the adjacent sliding blocks 10 to move. When the sliding blocks 10 move to the maximum distance, they stop moving. At this time, the gate 9 continues to rotate under the action of the lime water pressure, and the gate 9 pulls the adjacent thin ropes, and the thin ropes pull the adjacent rotating plates 11 to rotate. The rotating plates 11 squeeze the limiting protrusions on the two adjacent limiting plates 12, and the limiting plates 12 are deformed. When the rotating plate 11 passes over the limiting protrusions on the two adjacent limiting plates 12, the limiting plates 12 are reset under the action of their own elasticity. When the particulate impurities are discharged, the rolling blade 4 rotates to contact the adjacent rotating plate 11. At this time, the rolling blade 4 drives the adjacent rotating plate 11 to move, and the rotating plate 11 is in The two adjacent limit plates 12 are limited and keep pointing to the axis of the shell 1, that is, the rotating plate 11 is located on one of the diameters of the circle where the cross section of the shell 1 is located. At this time, the rotating plate 11 pulls the adjacent gate 9 to reset through the adjacent thin rope. When the gate 9 is reset, the two adjacent limit columns 13 are squeezed. The limit columns 13 compress the adjacent springs. When the gate 9 is reset, the two limit columns 13 re-limit the adjacent gate 9 under the action of the adjacent springs. At this time, the sliding block 10 returns to its original position and stops moving, and the rolling blade 4 continues to rotate and move the adjacent rotating plate 11. The rotating plate 11 squeezes the two adjacent limit plates 12 under the movement of the rolling blade 4 to deform, thereby breaking away from the limit of the two adjacent limit plates 12, and then the rotating plate 11 is reset under the action of the adjacent torsion spring.
