Description

Technical Field

[0001] The present disclosure relates to the technical field of carbonization and purification of lithium carbonate, and in particular to a plate-type carbonization device. Background Art

[0002] Carbonization, also known as dry distillation, carbonization, and coking, refers to the reaction process of heating and decomposing solid or organic matter in an airtight condition or a method of heating solid matter to produce liquid or gas (usually solid) products. This process does not necessarily involve cracking or pyrolysis. At present, the internal structure of the carbonizer is generally hollow, and carbon dioxide enters the carbonizer from the bottom and contacts the material from bottom to top to carbonize the material. In this process, the contact time between carbon dioxide and the material is short, and the rising route of bubbles inside the carbonizer is irregular, and the size of the bubbles is uncontrolled, resulting in low carbonization efficiency and long carbonization time.

[0003] For example, the prior art CN206188413U (hereinafter referred to as technology 1) discloses an improved high-efficiency carbonization tower, including a tower body and an air intake pipe extending from the top of the tower body to the bottom of the tower body, at the end of the air intake pipe, at least one strip groove extending horizontally along the bottom of the tower is arranged, and the strip groove is an inverted U-shaped groove, and a plurality of groups of notches are discretely arranged on the groove edge of the strip groove, and the gas escapes from the notches into the tower body solution to form dispersed bubbles. This scheme adopts an inclined guide plate 5, and the inclination directions of two adjacent groups of guide plates 5 are opposite, so that the bubbles return and rise along the guide plate 5.

[0004] For another example, the prior art CN102295306B (hereinafter referred to as technology 2) discloses a carbonizer for continuous synthesis of calcium carbonate, in which the serpentine reflux baffles used between the outlets of adjacent trays 5 of the carbonizer enable the materials to flow in an interlaced manner, and the carbonizer is provided with a sieve plate 53 perpendicular to the first tray at the outlet 52 of the first tray 51 of the first layer of the transverse tray 5. Through this scheme, the materials flow from top to bottom, and part of the carbon dioxide gas will move upward under the influence of buoyancy, and the CO2 utilization rate is high.

[0005] When the CO2 gas passes through the technology 1 at an uneven speed, the rate at which the gas escapes from the gap to form bubbles is uneven, and there is a possibility that bubbles of different speeds gather to form large bubbles, and technology 1 cannot separate large bubbles into small bubbles; although technology 2 is arranged in a serpentine shape through multiple tower plates 5 to slow down the rising speed of CO2, the device is only provided with a vertical sieve plate 53 on the first floor (i.e., the first tower plate 51) (its function is to separate the gathered large bubbles into small bubbles), and then in the process of CO2 rising from the bottom, before reaching the sieve plate 53, there is a possibility that multiple small bubbles integrate into large bubbles, and finally only the sieve plate 53 at the top of the carbonizer is separated into small bubbles, and the gas-liquid contact of calcium carbonate is not sufficient during carbonization. Similarly, when the carbonizer (carbonization tower) is carbonizing and purifying lithium carbonate, there is also a situation of insufficient gas-liquid contact during the carbonization process.

[0006] Compared with Technology 1, although Technology 2 can better solve the problem of bubbles rising too quickly, both technologies have the problem that the carbonization contact area between gas and liquid is small, and thus cannot guarantee a sufficient carbonization reaction.

The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0041] It should be noted that when an element is considered to be “connected to” another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0044] like Figure 1 and Figure 2 As shown, a plate-type carbonization device 10 of an embodiment is used for carbonization and purification of materials. Specifically, the material is lithium carbonate stock solution. The plate-type carbonization device 10 includes a carbonization tower 100 and a circulation mechanism 200. An exhaust pipe is provided at the top of the carbonization tower 100, and an exhaust valve 101 is provided on the exhaust pipe. The exhaust valve 101 is used to recover gas through the exhaust pipe when it is in an open state. In this embodiment, the gas is carbon dioxide.

[0045] The side wall of the carbonization tower 100 is provided with an air inlet pipe and a feed pipe, the air inlet pipe is provided with an air inlet valve 102, and the feed pipe is provided with a feed valve 103, wherein the air inlet valve 102 is arranged at the lower half of the carbonization tower 100, and the feed valve 103 is located above the air inlet valve 102, and the inner wall of the carbonization tower 100 is provided with a plurality of tower plates 110, and the plurality of tower plates 110 are spaced apart along the vertical direction of the carbonization tower 100, specifically, the tower plates 110 are welded to the inner wall of the carbonization tower 100, and each tower plate 110 is provided with a notch 1101, and the notches of the plurality of tower plates 110 are spaced apart from each other. The openings 1101 are staggered so that the material can flow back and forth repeatedly from top to bottom through the notches. Each tower plate 110 is provided with a plurality of holes 111. The circulation mechanism 200 includes a heat exchanger 210, a forced circulation drive assembly 220, a first circulation pipeline 230 and a second circulation pipeline 240. The carbonization tower 100 is connected to the heat exchanger 210 through the first circulation pipeline 230, that is, one end of the first circulation pipeline 230 is connected to the carbonization tower 100, specifically the top of the carbonization tower 100, and the other end of the first circulation pipeline 230 is connected to the heat exchanger 210. The heat exchanger 210 is connected to the carbonization tower 100 through the second circulation pipe 240, and the forced circulation drive component 220 is arranged on the second circulation pipe 240, that is, the heat exchanger 210 is also connected to the channel of the forced circulation drive component 220, and the channel of the forced circulation drive component 220 is also connected to one end of the second circulation pipe 240. Furthermore, the channel of the forced circulation drive component 220 is a pressure difference channel. When the forced circulation drive component 220 is working, the air pressure of the suction port of the forced circulation drive component 220 (the suction port is connected to the second circulation pipe 240) is reduced, and the air pressure of the outlet (the outlet connected to the heat exchanger 210) is increased. The forced circulation drive component 220 sucks the material from the suction port and sprays it out from the outlet through the pressure difference channel. The other end of the second circulation pipeline 240 is connected to the carbonization tower 100, specifically the bottom of the carbonization tower 100, so that the material, driven by the forced circulation drive component 220, passes through the channel of the forced circulation drive component 220 and the first circulation pipeline 230 from the second circulation pipeline 240 in sequence, and finally returns to the carbonization tower 100 from the top of the carbonization tower 100 to circulate the material. The second circulation pipeline 240 is provided with a discharge pipe, and the discharge pipe is provided with a discharge valve 2401, and the discharge valve 2401 is used to discharge the material.

[0046] In this embodiment, the diameter of the hole 111 on the tower plate 110 is about 1 cm, so that larger bubbles can be separated into uniform small bubbles. Each notch 1101 is staggered so that the path formed by multiple tower plates 110 is serpentine in shape, so as to reduce the rising rate of the bubbles and increase the gas-liquid contact area. The device can reduce the possibility of multiple carbon dioxide bubbles agglomerating to form large bubbles.

[0047] To facilitate relevant technical personnel to understand the working process, the following content explains the working principle of the device:

[0048] When the plate-type carbonization device 10 performs carbonization and purification operation on the material, the feed valve 103 is opened so that the material flows from the feed pipe at a feed flow rate (hereinafter referred to as flow rate) less than or equal to 75m / s. 3 / h into the carbonization tower 100, when the material added in the carbonization tower 100 reaches 1 / 3 of the liquid level, open the forced circulation drive component 220 to make the material circulate clockwise (that is, the material flow sequence is: carbonization tower 100, second circulation pipeline 240, forced circulation drive component 220, heat exchanger 210, first circulation pipeline 230, carbonization tower 100), and open the heat exchanger 210 at the same time to keep the internal environment of the entire device below 40°C. At this time, open the air inlet valve 102 to allow carbon dioxide to enter the carbonization tower 100 from the air inlet pipe. When the liquid level reaches 2 / 3, carbonize for 2h, open the discharge valve 2401, and control the discharge flow rate to be less than or equal to 75m 3 / h, so that the liquid level of the carbonization tower 100 is maintained at 2 / 3, at which time part of the material is discharged through the discharge valve 2401, and the other materials are circulated in a clockwise direction through the operation of the forced circulation drive assembly 220. The notch 1101 formed between the tower plate 110 and the inner wall of the carbonization tower 100 is arranged oppositely, so that the material repeatedly turns back and flows from top to bottom, that is, flows through the staggered notch 1101. The tower plate 110 is provided with a hole 111 with a diameter of about 1 cm. On the one hand, the hole 111 can prevent the rapid rise of carbon dioxide bubbles and increase the residence time of carbon dioxide bubbles in the liquid. On the other hand, when multiple bubbles gather to form large bubbles, the hole 111 can separate the large bubbles into equal small bubbles, so that the gas and liquid can fully contact each other during the entire carbonization process, and the reaction is more sufficient.

[0049] The outer wall of the carbonization tower 100 is also provided with a safety valve 104, which plays a role in protecting the stability of the system. When an abnormal state occurs during the operation of the device (such as excessive air pressure, etc.), the safety valve 104 is automatically opened to discharge the over-pressure medium to reduce the possibility of rupture or explosion of the device. The outer wall of the second circulation pipeline 240 is also provided with a sewage valve 2402. When the material is carbonized and purified, impurities such as iron filings, mud and sand are inevitably generated. The impurities can be discharged by opening the sewage valve 2402 to ensure the normal operation of the device.

[0050] like Figure 1 As shown, in one embodiment, a spray head 120 is provided on the inner wall of the carbonization tower 100, and the first circulation pipe 230 is connected to the inner wall of the carbonization tower 100 through the spray head 120, so that the material enters the carbonization tower 100 from the first circulation pipe 230 through the spray head 120.

[0051] Furthermore, if Figure 3As shown, the spray head 120 includes a spray plate 121 and a zigzag pipe 122 connected to each other. The zigzag pipe 122 is connected to the first circulation pipeline 230. The cross-sectional area of ​​the spray plate 121 gradually increases in the vertical direction away from the zigzag pipe 122 of the carbonization tower 100, so that the material can fully contact with the carbon dioxide bubbles after entering the carbonization tower 100.

[0052] like Figure 4 As shown, in one embodiment, a bottom pipe 130 is provided on the inner wall of the carbonization tower 100 , and the interior of the carbonization tower 100 is connected to the second circulation pipeline 240 through the bottom pipe 130 , so that the material enters the second circulation pipeline 240 from the carbonization tower 100 through the bottom pipe 130 .

[0053] like Figure 4 As shown, in one embodiment, the bottom pipe 130 includes a connected bending pipe 131 and a coil 132, the bending pipe 131 is connected to the second circulation pipe 240, and the coil 132 is connected to the inside of the carbonization tower 100, so that the material enters the second circulation pipe 240 from the bottom of the carbonization tower 100 through the coil 132 and the bending pipe 131 in sequence, and performs subsequent material circulation, and the coil 132 is provided with a plurality of circular holes 1321 to provide a uniform and stable carbon dioxide source for the carbonization tower 100. Further, the diameter of the circular hole 1321 is 0.5 cm.

[0054] like Figure 5 As shown, in one embodiment, one end of the heat exchanger 210 is connected to the cooling inlet pipe 211, and the other end of the heat exchanger 210 is connected to the cooling outlet pipe 212. The heat exchanger 210 is provided with isolated cooling channels 213 and material channels 214. The cooling inlet pipe 211 is connected to the cooling outlet pipe 212 through the cooling channel 213, and the first circulation pipeline 230 is connected to the second circulation pipeline 240 through the material channel 214. Further, when the heat exchanger 210 is working, the coolant enters the cooling channel 213 from the cooling inlet pipe 211 to cool the heat exchanger 210, maintain the normal working state of the heat exchanger 210, and finally exits from the cooling outlet pipe 212, during which the coolant does not pass through the first circulation pipeline 230 or the second circulation pipeline 240; at the same time, when the forced circulation drive assembly 220 is working, the material is sucked into the forced circulation drive assembly 220 and then enters the first circulation pipeline 230 through the material channel 214, during which the material does not pass through the cooling channel 213. In this way, the working effects of the two do not interfere with each other. In addition, the bottom end of the heat exchanger 210 is connected to a drain pipe, which is provided with a drain valve 215. When the device stops working after carbonization is completed, the coolant is stopped from entering the cooling channel 213, and the drain valve 215 is opened to discharge the coolant in the cooling channel 213 from the drain pipe.

[0055] like Figure 6As shown, in one embodiment, the forced circulation drive assembly 220 includes a forced circulation motor 221 and a forced circulation pump 222, the forced circulation pump 222 is electrically connected to the forced circulation motor 221, and the forced circulation pump 222 is arranged in the second circulation pipeline 240. Further, the forced circulation pump 222 is provided with a pressure difference channel, and both sides of the pressure difference channel (i.e., the outlet and the suction port) are respectively connected to the heat exchanger 210 and the second circulation pipeline 240. It can be understood that the forced circulation motor 221 is used to drive and control the state of the forced circulation pump 222. When the material is carbonized and purified, the forced circulation motor 221 is powered on to drive the forced circulation pump 222 so that the material circulates. Otherwise, the forced circulation motor 221 is disconnected from the power supply and the forced circulation pump 222 does not work.

[0056] like Figure 7 As shown, in one embodiment, the first circulation pipeline 230 includes a first sub-pipeline 231, a first iron remover 232 and a second sub-pipeline 233 which are connected in sequence, the first sub-pipeline 231 is connected to the heat exchanger 210, and the second sub-pipeline 233 is connected to the carbonization tower 100. Specifically, the second sub-pipeline 233 is connected to the interior of the carbonization tower 100 through the spray head 120, so that the material is driven by the forced circulation drive component 220, passes through the heat exchanger 210, passes through the first sub-pipeline 231, the first iron remover 232 and the second sub-pipeline 233 in sequence, and finally enters the interior of the carbonization tower 100.

[0057] like Figure 7 As shown, in one embodiment, the first sub-pipeline 231 and the second sub-pipeline 233 are both provided with a first ball valve 234. Further, the first ball valve 234 is arranged on both sides of the first iron remover 232. When the magnetic material adsorbed by the first iron remover 232 reaches a predetermined value, the first ball valve 234 is closed to facilitate subsequent cleaning of the first iron remover 232, thereby ensuring that the plate-type carbonization device 10 can operate stably.

[0058] Furthermore, the first sub-pipeline 231 is provided with a first branch pipe 2311 and a second branch pipe 2312, and the second sub-pipeline 233 is provided with a third branch pipe 2331 and a fourth branch pipe 2332. The first branch pipe 2311 is connected to the third branch pipe 2331 through the first iron remover 232 to form a branch pipe; the second branch pipe 2312 is connected to the fourth branch pipe 2332 through the first iron remover 232 to form a branch pipe. The first ball valve 234 is respectively provided on the first branch pipe 2311, the second branch pipe 2312, the third branch pipe 2331 and the fourth branch pipe 2332, so that when any first iron remover 232 adsorbs magnetic materials to a predetermined value, the first ball valve 234 of the corresponding branch pipe is closed to clean the first iron remover 232 to ensure the stability of material carbonization.

[0059] like Fig. 9As shown, in one embodiment, the second circulation pipeline 240 includes a third sub-pipeline 241, a second iron remover 242 and a fourth sub-pipeline 243 which are connected in sequence, the discharge pipe and the drain valve 2402 are both located in the fourth sub-pipeline 243, the third sub-pipeline 241 is connected to the heat exchanger 210 through the channel of the forced circulation drive component 220, and the fourth sub-pipeline 243 is connected to the carbonization tower 100. Specifically, the fourth sub-pipeline 243 is connected to the interior of the carbonization tower 100 through the bottom pipe 130, so that the material is driven by the forced circulation drive component 220, passes through the fourth sub-pipeline 243, the second iron remover 242 and the third sub-pipeline 241 from the bottom of the carbonization tower 100 in sequence, and then enters the pressure difference channel of the forced circulation drive component 220, and finally passes through the heat exchanger 210, the first sub-pipeline 231, the first iron remover 232 and the second sub-pipeline 233 in sequence, and returns to the carbonization tower 100 from the top.

[0060] like Fig. 9 As shown, in one embodiment, the third sub-pipeline 241 and the fourth sub-pipeline 243 are both provided with a second ball valve 244. Further, the second ball valve 244 is arranged on both sides of the second iron remover 242.
