Description

Technical Field

[0001] The utility model relates to the technical field of carbonization tower equipment, in particular to a carbonization tower gas dispersion device. Background Art

[0002] Traditional gas-liquid mixing reaction devices will have a large number of large bubbles, which will prevent the gas and liquid from fully reacting. The gas-liquid mixture reaction time is long, and the unreacted gas needs to be recovered secondary, increasing the recovery cost. In addition, the mixing path of the gas-liquid mixture inside the carbonization tower is short, the mixing degree is light, and sufficient mixing cannot be achieved.

[0003] Document CN201020302544 discloses a carbonization tower for uniform gas-liquid mixing, comprising a tower body and an air inlet pipe. The utility model features a divider at the bottom of the tower body that vertically divides the interior into several independent zones. The divider's height is no more than half the tower body's height, and each independent zone is provided with at least one air inlet pipe. This structure allows the gas to enter the carbonization tower through the air inlet pipe without undergoing further dispersion, which can lead to uneven contact between the gas and the liquid, hindering the reaction process.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above problems, the utility model discloses a carbonization tower gas dispersion device, which disperses large bubbles into small bubbles through the gas-liquid dispersion device, increases the contact area between the gas and the slurry, and improves the reaction efficiency. The gas-liquid dispersion devices are staggered, and the ends of the gas-liquid dispersion devices do not exceed the central axis of the carbonization tower, so that the gas-liquid mixture presents an S shape during stirring, increases the reaction path, and makes the reaction more complete.

[0006] The technical solution of the utility model is as follows: a carbonizing tower gas dispersing device comprises a gas-liquid dispersing device located in the carbonizing tower, a slurry inlet and a gas inlet are provided on the carbonizing tower, the gas-liquid dispersing device as a whole is placed obliquely between the carbonizing tower, a stirring shaft and a stirring head portion of the gas-liquid dispersing device are located in the carbonizing tower, the gas-liquid dispersing device are installed relative to each other, and the ends do not exceed the central axis of the carbonizing tower, and the stirring head comprises two adjacent rows of stirring blades.

[0007] Preferably, a through hole for passing the stirring shaft is provided on the side of the carbonization tower, and the stirring shaft extends into the interior of the carbonization tower through the through hole.

[0012] By adopting the above technical solution, when the gas-liquid dispersion device is working in the carbonization tower, the internal gas and slurry can form a uniform S-shaped route between the bottom of the carbonization tower and the first gas-liquid dispersion device, and between the first gas-liquid dispersion device and the second gas-liquid dispersion device.

[0015] By adopting the above technical solution, the stirring head is generally downward-pressing, which can change the path of the mixture of gas and slurry in the carbonization tower, and change the vertical route into an S-shaped route. This will increase the reaction time of the mixture in the gas-liquid dispersion device, and can also fully disperse the large bubbles in the gas-liquid dispersion device, so that the gas and slurry can be fully reacted, and ultimately improve the reaction efficiency of the gas and slurry.

[0016] Preferably, the edge of the bent portion is inclined toward one side, and the bent portions on both sides of the edge of the scattering disk are inclined toward one side.

[0017] Preferably, there are an even number of carbonization towers, the slurry outlets between adjacent carbonization towers are located at the lower part of the carbonization towers, and the slurry inlets and slurry outlets of the first and last carbonization towers are both located at the upper part of the carbonization towers.

[0018] By adopting the above technical solution, after the slurry and gas are mixed and reacted in the first carbonization tower, they pass through the second carbonization tower for sufficient reaction and mixing again, and then pass through the next one, and so on, so that the gas and liquid can be fully mixed and reacted.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] like Figure 1-6 As shown, the carbonizing tower gas dispersion device includes a gas-liquid dispersion device 2 located in the carbonizing tower 1. A slurry inlet 102 and a gas inlet 103 are provided on the carbonizing tower 1. The gas-liquid dispersion device 2 is placed obliquely between the carbonizing tower 1 as a whole. The stirring shaft 4 and the stirring head 5 of the gas-liquid dispersion device 2 are partially located in the carbonizing tower 1. The gas-liquid dispersion device 2 is installed relative to each other, and the ends do not exceed the central axis of the carbonizing tower 1. The stirring head 5 includes two adjacent rows of stirring blades 502.

[0033] A through hole is provided on the side of the carbonization tower 1 for passing the stirring shaft 4, and the stirring shaft extends into the interior of the carbonization tower 1 through the through hole. The end of the stirring shaft 4 located outside the carbonization tower 1 is located at the output end of the motor and the reducer. The stirring shaft 4 is driven by the motor and the reducer to drive the stirring blades 502 in the carbonization tower 1 to stir the slurry and gas inside.

[0034] The inclination angle between the gas-liquid dispersing device 2 as a whole and the carbonizing tower 1 is 30°-35°. The stirring head 5 and the stirring shaft 4 in the carbonizing tower 1 are installed upward in sequence, and the ends of the stirring head 5 do not exceed the central axis of the carbonizing tower 1. When the relatively arranged gas-liquid dispersing device 2 works in the carbonizing tower 1, the mixture of internal gas and slurry forms an S-shaped flow curve, thereby allowing the gas-liquid mixture in the gas-liquid dispersing device 2 to fully dissolve and react.

[0035] The vertical distance between the connection position of the stirring shaft 4 and the carbonization tower 1 and the bottom of the carbonization tower 1 is 1-1.1 meters. The vertical distance between adjacent stirring shafts 4 is consistent with the distance between the stirring shaft 4 and the bottom of the carbonization tower 1. When the gas-liquid dispersion device 2 is working in the carbonization tower 1, the internal gas and slurry can form an even S-shaped route between the bottom of the carbonization tower 1 and the first gas-liquid dispersion device 2, and between the first gas-liquid dispersion device 1 and the second gas-liquid dispersion device 2.

[0036] The stirring head 5 includes a scattering disk 501 and a stirring blade 502. The end of the stirring shaft 4 is fixed at the center of the scattering disk 501. The scattering disk 501 is provided with a stirring blade 502 in the circumferential direction. The stirring blade 502 is located at the edge of the stirring head 5. The stirring head 5 includes a connecting portion 5021 and a bending portion 5022. The bending portion 5022 of the stirring head 5 is perpendicular to the connecting portion 5021. The bending directions of adjacent connecting portions 5021 are opposite. The edge of the bending portion 5022 is inclined to one side. The bending portions 5022 on both sides of the edge of the scattering disk 501 are inclined to one side. The stirring head 5 is of a downward pressure type as a whole, which can change the path of the mixture of gas and slurry in the carbonization tower 1, and make the vertical route become an S-shaped route. This will increase the reaction time of the mixture in the gas-liquid scattering device 2, and can also fully disperse the large bubbles in the gas-liquid scattering device 2, so that the gas and slurry can be fully reacted, and ultimately improve the reaction efficiency of the gas and slurry.

[0037] There are an even number of carbonization towers 1, and the slurry outlet 102 between adjacent carbonization towers 1 is located at the lower part of the carbonization tower 1. The slurry inlet 101 and the slurry outlet 102 of the head and tail carbonization towers 1 are both located at the upper part of the carbonization tower 1. After the slurry and gas are mixed and reacted in the first carbonization tower 1, they pass through the second carbonization tower 1 for sufficient reaction and mixing again, and then pass through the next one, and so on. In this way, the gas and liquid can be fully mixed and reacted.

[0038] Observation ports 3 are provided on the upper and lower sides of the carbonization tower 1. A gas inlet 103 is provided below the slurry outlet 102 of the carbonization tower 1. The gas inlet 103 extends into the bottom side of the carbonization tower 1 through an air inlet pipe. The gas inlets 103 between adjacent carbonization towers 1 are connected to each other. The bottom of the carbonization tower is the slurry outlet. The observation port 3 can be used to observe the reaction situation in the carbonization tower 1. The gas entering allows the slurry and gas to fully mix and react, and the slurry outlet discharges the internal gas and liquid.

[0039] Working principle: The slurry is input into the carbonization tower 1 through the slurry inlet 101. At the same time, the gas inlet 103 enters the carbonization tower 1 from the bottom of the carbonization tower, and the gas-liquid breaking device 2 is started. Then the slurry and gas inside the carbonization tower 1 are broken up so that the two are fully mixed and reacted. Then, the slurry is transported to the next carbonization tower 1 through the slurry outlet 102 at the bottom of the carbonization tower 1. After passing through multiple carbonization towers 1, it flows out from the slurry outlet 102 at the top of the last carbonization tower 1.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
