Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization towers, and more particularly to a coke oven gas desulfurization tower. Background Art

[0002] Among the equipment for desulfurizing industrial waste gas, tower-type equipment is mostly used, which is a desulfurization tower. The desulfurization tower was originally most widely applied with granite masonry. It utilizes the principle of water film desulfurization and dust removal, also known as granite water film desulfurization dust collector, or hempstone water film desulfurization dust collector. Its advantages are easy maintenance, and by formulating different dust removal agents, the effects of dust removal and desulfurization (denitrification) can be achieved simultaneously.

[0003] In the process of implementing the present invention, it is found that at least the following problems in the prior art have not been solved: When gas enters the coke oven gas desulfurization tower and the thick slurry reacts with sulfur dioxide in the gas, some solid particles in the gas will adhere to the inner surface of the tower body of the desulfurization tower. If they accumulate in the tower body for a long time, the inside of the tower body will be corroded, damaging the desulfurization tower. After the inner surface of the tower body is cleaned, the attached solid particles will fall into the slurry at the lower end inside the tower body. When the slurry at the lower end inside the tower body is discharged from the tower body, the fallen solid particles will block the slurry discharge port, resulting in unsmooth slurry discharge and affecting the normal operation of the desulfurization tower.

[0004] Therefore, a coke oven gas desulfurization tower is proposed. Summary of the Invention

[0005] The present invention provides a coke oven gas desulfurization tower, which can clean the solid particles attached to the inner surface of the tower body of the coke oven gas desulfurization tower, prevent the inside of the tower body from being corroded and damaging the desulfurization tower. At the same time, it also filters the solid particles in the discharged slurry and collects the filtered solid particles to avoid blockage of the slurry discharge port, and at the same time facilitates the cleaning of the tower body, saving manpower, so as to solve the problems raised in the above background art.

[0006] The present invention provides a coke oven gas desulfurization tower, including a tower body. A slurry discharge port is provided at the lower end of one side of the tower body. An air inlet is opened at the middle position on the outer surface of the other side of the tower body. A demisting plate is fixedly installed at the upper end inside the tower body. A clean water spraying mechanism is fixedly installed below the demisting plate at the upper end inside the tower body. A slurry spraying mechanism is installed in the middle inside the tower body. A collection channel is fixedly installed on the inner surface of the tower body below the slurry spraying mechanism. A plurality of diversion pipes are provided at the lower end of the collection channel, and the plurality of diversion pipes correspond to the positions of a plurality of anticorrosion cylinders. A cleaning module is fixedly installed on the inner surface of the tower body below the collection channel.

[0007] Preferably, the cleaning module includes multiple groups of support rods. The bottom ends of the multiple groups of support rods are fixedly connected to the inner surface of the tower body, and the top ends are fixedly connected with support seats. A first rotating shaft is rotatably connected inside the multiple groups of support seats. A flexible shaft is fixedly connected inside the first rotating shaft, and the first rotating shaft penetrates through the anti-corrosion cylinder. The flexible hose penetrates through the support seat and is fixedly connected to the flexible shaft. The end of the flexible hose is fixedly connected above the second rotating shaft. The second rotating shaft penetrates through the upper outer surface of the filter screen below. A bearing is fixedly connected between the filter screen and the rotating shaft. A brush is movably installed on the outer surface of the lower end of the bearing. Multiple springs are arranged at the lower edge of the outer circumferential surface of the filter screen. A collection bag is movably installed at the lower ends of the multiple springs.

[0008] Preferably, a cleaning port is provided at the lower end of one side of the tower body close to the air inlet, and the cleaning port corresponds to the position of the collection belt.

[0009] Preferably, the filter screen is hemispherical, and multiple cleaning brushes are closely attached to the inner surface of one side of the filter screen.

[0010] Preferably, the collection belt is annular and made of an elastic memory material, and a notch is provided on one side of the collection belt.

[0011] Preferably, an anti-corrosion coating is applied to the surface of the anti-corrosion cylinder and the inner wall of the tower body.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: When the coal gas enters the tower body from the air inlet, the thick slurry sprayed by the slurry spraying mechanism reacts with the gas to remove sulfur dioxide in the coal gas. The gas from which sulfur dioxide has been removed is separated from the solids in the gas through the clean water spraying mechanism and the demisting plate. At this time, the slurry in the collection channel flows through the diversion pipe to the anti-corrosion cylinder. A large amount of slurry will cause the anti-corrosion cylinder to tilt downward under gravity. A large amount of slurry will cause the anti-corrosion cylinder to tilt downward under gravity, thereby driving the first rotating shaft to rotate. Since a flexible shaft is arranged inside the first rotating shaft and the flexible shaft is fixedly connected to the flexible hose, and since the flexible hose penetrates through the support seat and the rotating shaft and is fixedly connected to the flexible shaft, the power generated by the up-and-down movement of multiple anti-corrosion cylinders is transmitted to the flexible shaft through the first rotating shaft fixedly installed on the anti-corrosion cylinder, so that the first rotating shaft connected to the flexible hose drives the brush to rotate on the inner surface of the filter screen for cleaning, so that the solid particles attached to the surface of the filter screen are cleaned onto the collection belt, and then the slurry is discharged from the tower body through the slurry discharge port. At this time, the solid particles are gathered on the collection belt, which not only filters and collects the solid particles in the slurry, prevents the slurry discharge port 3 from being blocked, but also cleans the filter screen 1058, facilitates the maintenance of the desulfurization tower, and saves manpower.

[0022] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0023] A coke oven gas desulfurization tower, comprising a tower body 1, a slurry discharge port 3 is provided at the lower end of one side of the tower body 1, an air inlet 2 is provided at the middle position of the outer surface of the other side of the tower body 1, a demisting plate 101 is fixedly installed at the upper end inside the tower body 1, a clean water spraying mechanism 102 is fixedly installed at the upper end inside the tower body 1 and below the demisting plate 101, a slurry spraying mechanism 103 is installed at the middle inside the tower body 1 and above the air inlet 2, a collection channel 104 is fixedly installed on the inner surface of the tower body 1 and below the lower end of the air inlet 2, the collection channel 104 is used for collecting the treated slurry, a plurality of diversion pipes 1041 are provided at the lower end of the collection channel 104, the diversion pipes 1041 are used for supplying slurry to the anticorrosion cylinder 1051 in the cleaning module, and the plurality of diversion pipes 1041 correspond to the plurality of anticorrosion cylinders 1051 in position, a cleaning module 105 is fixedly installed on the inner surface of the tower body 1 below the collection channel 104, the cleaning module 105 is used for cleaning solid particles to avoid corrosion of the tower body 1. During operation, the coal gas enters the tower body 1 from the air inlet 2, the thick slurry sprayed by the slurry spraying mechanism 103 reacts with the gas to remove sulfur dioxide in the coal gas, and the gas from which sulfur dioxide has been removed undergoes solid separation when passing through the clean water spraying mechanism 102 and the demisting plate 101, preventing some solid particles in the gas from adhering to the inner surface of the tower body 1, thereby achieving the purpose of avoiding corrosion of the tower body 1.

[0024] Specifically, the cleaning module includes multiple groups of support rods 1053. The bottom ends of the multiple groups of support rods 1053 are fixedly connected to the inner surface of the tower body 1, and the top ends of the support rods are fixedly connected with support seats 1052. A first rotating shaft 1054 is rotatably connected inside the multiple groups of support seats 1052. A flexible shaft 105401 is fixedly connected inside the first rotating shaft 1054, and the first rotating shaft 1054 penetrates through the inside of the anti-corrosion cylinder 1051. The power generated by the up and down movement of the anti-corrosion cylinder 1051 is transmitted to the flexible shaft 105401 through the first rotating shaft 1054 fixedly installed on the anti-corrosion cylinder 1051. The hose 1055 penetrates through the support seat 1052 and is fixedly connected to the flexible shaft 105401, and the end of the hose 1055 is fixedly connected above the second rotating shaft 1056. The torque at the end of the hose 1055 is increased through the flexible shaft 105401 to rotate the second rotating shaft 1056. The lower part of the second bearing 1057 penetrates through the outer surface of the upper end of the filter screen 1058. A bearing 1057 is fixedly connected between the filter screen 1058 and the rotating shaft. Multiple groups of brush hairs 1059 are movably installed on the outer surface of the lower end of the bearing 1057. The rotation of the second rotating shaft 1056 drives the bearing 1057. Since the bearing 1057 is connected to multiple groups of brush hairs 1059, the brush hairs 1059 start to clean on the inner surface of the filter screen 1058. The upper surface of the filter screen 1058 is in contact with the bottom of the anti-corrosion cylinder 1051. Multiple groups of springs 1060 are provided at the bottom of the filter screen 1058. A collecting belt 1061 is movably installed at the lower ends of the multiple groups of springs 1060. By the anti-corrosion cylinder 1051 knocking on the surface of the filter screen 1058, the springs 1060 vibrate due to the pressure, so that the solid particles attached to the surface of the filter screen 1058 are cleaned onto the collecting belt 1061 at the lower ends of the springs 1060. During the working process, the diversion pipe 1041 supplies slurry to the anti-corrosion cylinder 1051. A large amount of slurry will cause the anti-corrosion cylinder 1051 to tilt under the action of gravity, thereby driving the first rotating shaft 1054 to rotate. Since a flexible shaft 105401 is arranged inside the first rotating shaft 1054 and the flexible shaft 105401 is fixedly connected to the hose 1055, and the hose 1055 penetrates through the support seat 1052 and the first rotating shaft 1054, the power generated by the up and down movement of multiple anti-corrosion cylinders 1051 is transmitted to the flexible shaft 105401 through the first rotating shaft 1054 fixedly installed on the anti-corrosion cylinder 1051, so that the second rotating shaft 1054 connected to the hose 1055 drives the brush hairs 1059 to rotate on the inner surface of the filter screen 1058 for cleaning, so that the solid particles attached to the surface of the filter screen 1058 are cleaned onto the collecting belt 1061, and then the slurry is discharged from the tower body 1 through the slurry discharge port 3. At this time, the solid particles are gathered on the collecting belt 1061, which not only filters and collects the solid particles in the slurry, prevents the slurry discharge port 3 from being blocked, but also cleans the filter screen 1058, facilitates the maintenance of the desulfurization tower, and saves manpower.

[0025] Specifically, a cleaning port is provided at the lower end of one side of the tower body 1 near the air inlet 2, and the cleaning port corresponds to the position of the collecting belt 1061. When the solid particles are fully accumulated on the collecting belt 1061, the maintenance personnel can directly open the cleaning port and take out the collecting belt 1061 through the cleaning port, so that the solid particles on the collecting belt 1061 can be cleaned up.

[0026] Specifically, the filter screen 1058 is hemispherical, and multiple groups of the brush 1059 are closely attached to the inner surface of one side of the filter screen 1058. When the brush 1059 rotates, it can clean the solid particles on the filter screen 1058. Since the filter screen 1058 is hemispherical, the solid particles attached to the filter screen 1058 fall to the lower edge of the outer circular surface of the filter screen 1058 after being cleaned, and finally accumulate on the collecting belt 1061.

[0027] Specifically, the collecting belt 1061 is annular and made of an elastic memory material. A notch is provided on one side of the collecting belt 1061. By setting the notch, the collecting belt 1061 can be drawn out through the cleaning port on the filter screen 1058. Also, since the collecting belt 1061 is annular and made of an elastic memory material, after the solid particles on the collecting belt 1061 are cleaned, the collecting belt 1061 can be easily put into the cleaning port.

[0028] Specifically, an anti-corrosion coating is applied to the surface of the anti-corrosion cylinder and the inner wall of the tower body to prevent the anti-corrosion cylinder from being corroded.

[0029] Usage method: When the gas enters the tower body 1 from the air inlet 2, the concentrated slurry sprayed by the slurry spraying mechanism 103 reacts with the gas to remove sulfur dioxide in the gas. The gas after removing sulfur dioxide undergoes solid separation when passing through the clean water spraying mechanism 102 and the demisting plate 101. At this time, the slurry in the collecting channel 104 flows through the diversion pipe 1041 to the anti-corrosion cylinder 1051. A large amount of slurry will cause the anti-corrosion cylinder 1051 to tilt under the action of gravity, driving the first rotating shaft 1054 to rotate. Since a flexible shaft 105401 is arranged inside the first rotating shaft 1054, the flexible shaft 105401 is fixedly connected with a flexible hose 1055, and the flexible hose 1055 penetrates through the support seat 1052 and the rotating shaft. Thus, the power generated by the up and down movement of multiple anti-corrosion cylinders 1051 is transmitted to the flexible shaft 105401 through the first rotating shaft 1054 fixedly installed on the anti-corrosion cylinder 1051, causing the second rotating shaft 1056 connected to the flexible hose 1055 to drive the brush 1059 to rotate on the inner surface of the filter screen 1058 for cleaning. As a result, the solid particles attached to the surface of the filter screen 1058 are cleaned onto the collecting belt 1061, and then the slurry is discharged from the tower body 1 through the slurry discharge port 3. At this time, the solid particles accumulate on the collecting belt 1061, not only filtering and collecting the solid particles in the slurry to prevent the slurry discharge port 3 from being blocked, but also cleaning the filter screen 1058, facilitating the maintenance of the desulfurization tower and saving manpower.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
