Description

Technical Field

[0001] This invention relates to the field of chemical industrial production equipment technology, specifically to a liquid distribution device and a carbon-containing material conversion and reforming reactor. Background Technology

[0002] High-salt wastewater from the coal chemical industry, battery waste liquid, pharmaceutical waste liquid, dyeing and printing waste liquid, liquids containing heavy metal pollutants, and concentrated leachate after membrane treatment from other industries are difficult and costly to treat.

[0003] In existing technologies, a carbon-containing material reforming reactor can spray high-salt wastewater and other waste liquids into the reactor interior. While cooling, humidifying, and reducing dust in the product gas, dissolved impurities such as salt in the waste liquid are adhered to and absorbed by the carbon-containing material. The impurities then enter the high-temperature zone with the carbon-containing material to participate in the reforming reaction. The residue is discharged in a molten state at temperatures above 1200°C through the reactor slag discharge control system and quenched into solid particles, which become building materials with good economic utilization value.

[0004] Because industrial wastewater such as high-salt wastewater contains clumps or large molecular aggregates, when it is sprayed into the reactor, the clumps or large molecular aggregates have poor diffusion and distribution and are prone to clogging the pipes or nozzles, thus affecting the reforming and conversion reaction. Summary of the Invention

[0009] According to some embodiments of the present invention, the distribution pipe is a straight pipe, and multiple crushing spray heads are provided and evenly distributed along the length direction of the distribution pipe.

[0010] According to some embodiments of the present invention, the distribution pipe includes multiple straight pipes and multiple connectors, and two adjacent straight pipes are connected through the connectors.

[0011] According to some embodiments of the present invention, both the feed pipe and the distribution pipe are made of alloy material.

[0012] According to some embodiments of the present invention, the flow cross-sectional area of ​​the diameter of the feed pipe and the distribution pipe is greater than or equal to five times the sum of the minimum flow cross-sectional areas of the plurality of crushing nozzles.

[0013] According to some embodiments of the present invention, the crushing injection head includes: a housing, a limiting body, and a self-propelled breaker; one end of the limiting body extends into the housing, the limiting body is adapted to connect the housing and the distribution pipe, and a crushing cavity is formed between the limiting body and the housing; the self-propelled breaker is rotatably disposed in the crushing cavity, and the self-propelled breaker slides in the crushing cavity.

[0014] According to some embodiments of the present invention, the self-propelled hydraulic breaker is provided with multi-head crushing spiral teeth at one end near the housing, and the radial gap between the outer periphery of the multi-head crushing spiral teeth and the inner wall of the crushing cavity is 0.2-1 mm.

[0015] According to some embodiments of the present invention, the first inlet is connected to a gas instrument control valve, the second inlet is connected to a waste liquid instrument control valve, both the gas instrument control valve and the waste liquid instrument control valve are pneumatically or electrically driven, and the gas instrument control valve and the waste liquid instrument control valve form an interlocking relationship.

[0016] The present invention also proposes a carbon-containing material conversion and reforming reactor, including a reactor, wherein the reactor is provided with the liquid distribution device described above.

[0017] The technical solution of this invention has the following advantages:

[0018] 1. The liquid distribution device provided by the present invention includes a crushing gas introduced into the feed pipe through a first inlet and a waste liquid introduced into the feed pipe through a second inlet. The crushing gas and waste liquid mix and flow into the distribution pipe and enter the crushing nozzle. Under the action of the pressure difference between the waste liquid and the crushing gas mixture, the self-propelled breaker hammer rotates at high speed, thereby crushing the large molecular aggregates in the waste liquid, so as to avoid the large molecular aggregates from clogging the nozzle and improve the uniformity of liquid distribution.

[0019] 2. The liquid distribution device provided by the present invention has both the feed pipe and the distribution pipe made of alloy material. Alloy material has good wear resistance and corrosion resistance, thereby ensuring trouble-free operation and improving the reliability of the liquid distribution device.

[0020] 3. The liquid distribution device provided by the present invention has a flow cross-sectional area of ​​the diameter of the feed pipe and the distribution pipe that is greater than or equal to five times the sum of the minimum flow cross-sectional areas of the plurality of crushing nozzles, which facilitates the smooth passage of the mixture of crushing gas and waste liquid through the feed pipe and the distribution pipe and its uniform distribution to each crushing nozzle, while also helping to reduce the resistance and scouring wear of the mixture of crushing gas and waste liquid.

[0021] 4. The liquid distribution device provided by the present invention forms an interlock relationship between the gas control valve and the waste liquid control valve, and adjusts according to the flow ratio to ensure the precise matching of the flow ratio of the breaker gas and the waste liquid, thereby driving the self-propelled breaker, realizing automated control, and reducing the difficulty of operation.

[0027] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Reference Figure 1 and Figure 2As shown, this invention proposes a liquid distribution device for the spray distribution of high-salt wastewater, comprising: a feed pipe 1, a distribution pipe 2, and a crushing spray head 3; the feed pipe 1 is provided with a first inlet and a second inlet; the first inlet is suitable for introducing crushing gas, and the second inlet is suitable for introducing waste liquid; the distribution pipe 2 is connected to the feed pipe 1, and a plurality of mounting holes are provided on the lower side wall of the distribution pipe 2; the number of crushing spray heads 3 is several, which are provided on the mounting holes, and the crushing spray heads 3 are connected to the distribution pipe 2. The crushing gas and waste liquid flow through the feed pipe 1 and the distribution pipe 2 and then enter the crushing spray head 3. The crushing spray head 3 is provided with a self-powered crushing hammer 33, which is suitable for crushing large molecular aggregates in the waste liquid.

[0032] Specifically, the crushing gas is introduced into the feed pipe 1 through the first inlet, and the waste liquid is introduced into the feed pipe 1 through the second inlet. The crushing gas and waste liquid mix in the feed pipe 1 and flow into the distribution pipe 2, and then into the crushing nozzle 3. Under the action of the pressure difference between the waste liquid and the crushing gas mixture, the self-propelled breaker 33 rotates at high speed, thereby crushing the large molecular aggregates in the waste liquid, so as to avoid the large molecular aggregates from clogging the nozzle and improve the uniformity of liquid distribution.

[0033] It is understandable that the crushing gas and waste liquid are introduced into the feed pipe 1 in proportion to form a mixture in the feed pipe 1. When the crushing gas and waste liquid flow through the self-operated breaker 33, under the action of the pressure difference between the waste liquid and the crushing gas, the self-operated breaker 33 rotates at high speed according to the principle that action and reaction forces are equal, thereby realizing the crushing of large molecular aggregates in the waste liquid.

[0034] In some embodiments of the present invention, the distribution pipe 2 is an annular pipe, and multiple crushing spray heads 3 are provided and evenly distributed along the circumferential direction, with the number of mounting holes and crushing spray heads 3 being the same.

[0035] Specifically, the distribution pipe 2 is an annular pipe, which is formed by one or more annular pipes joined together to form a ring. The mounting holes are opened on the lower side wall of the annular pipe and are evenly distributed along the circumference to achieve uniform distribution of waste liquid. The number of mounting holes is the same as that of the crushing spray head 3.

[0036] In some embodiments of the present invention, the distribution pipe 2 is a straight pipe, and multiple crushing spray heads 3 are provided and are evenly distributed along the length direction of the distribution pipe 2.

[0037] In some embodiments of the present invention, the distribution pipe 2 includes multiple straight pipes and multiple connectors, and two adjacent straight pipes are connected by connectors.

[0038] Specifically, the distribution pipe 2 is a straight pipe, or is composed of multiple straight pipes joined together. The connector can be a straight connector or an angle connector, so that the distribution pipe 2 can be formed into various shapes, improving adaptability and versatility.

[0039] Specifically, when the connector is a right-angle joint and there are four straight pipes, the distribution pipe 2 can be enclosed to form a rectangle.

[0040] Understandably, the number of crushing nozzles 3 is determined according to the specifications applied to the reactor 6. Based on the requirements of uniformity and coverage, the number of crushing nozzles 3 can be one or more.

[0041] In some embodiments of the present invention, the distribution pipe 2 is an annular pipe, or a steel pipe bent into an annular shape, with 2-16 mounting holes evenly arranged in a ring on the lower side of the distribution pipe 2 for mounting the crushing injection head 3. The crushing injection head 3 is installed vertically to ensure that the self-propelled breaker 33 can rotate freely at high speed, reducing frictional resistance and extending the trouble-free operating cycle.

[0042] In some embodiments of the present invention, both the feed pipe 1 and the distribution pipe 2 are made of alloy material.

[0043] Specifically, both the feed pipe 1 and the distribution pipe 2 are made of alloy materials, which have good wear resistance and corrosion resistance, thus ensuring trouble-free operation and improving the reliability of the liquid distribution device.

[0044] In some embodiments of the present invention, the cross-sectional area of ​​the diameter of the feed pipe 1 and the distribution pipe 2 is greater than or equal to five times the sum of the minimum cross-sectional areas of the plurality of crushing nozzles 3.

[0045] Specifically, the flow cross-sectional area of ​​the feed pipe 1 and the distribution pipe 2 is greater than or equal to five times the sum of the minimum flow cross-sectional areas of the multiple crushing nozzles 3. This facilitates the smooth passage of the mixture of crushing gas and waste liquid through the feed pipe 1 and the distribution pipe 2 and its uniform distribution to each crushing nozzle 3. At the same time, it helps to reduce the resistance and scouring wear of the mixture of crushing gas and waste liquid.

[0046] Reference Figure 2 As shown, in some embodiments of the present invention, the crushing nozzle 3 includes: a housing 31, a limiting body 32, and a self-propelled breaker 33; one end of the limiting body 32 extends into the housing 31, the limiting body 32 is adapted to connect the housing 31 and the distribution pipe 2, and a crushing cavity 34 is formed between the limiting body 32 and the housing 31; the self-propelled breaker 33 is rotatably disposed in the crushing cavity 34, and the self-propelled breaker 33 slides in the crushing cavity 34.

[0047] Specifically, the limiting body 32 and the shell 31 enclose a crushing cavity 34. Waste liquid and crushing gas flow through the limiting body 32 into the crushing cavity 34. The self-powered breaker 33 is rotatably mounted in the crushing cavity 34. When the waste liquid and crushing gas flow through the self-powered breaker 33, a pressure difference is generated. Under the action and reaction forces, the self-powered breaker 33 rotates at high speed and slides along the length of the crushing cavity 34, thereby crushing the clumps and large molecular aggregates in the waste liquid.

[0048] According to some embodiments of the present invention, the self-propelled hydraulic breaker 33 is provided with multi-head crushing spiral teeth 331 at one end near the housing 31, and the radial gap between the outer periphery of the multi-head crushing spiral teeth 331 and the inner wall of the crushing cavity 34 is 0.2-1mm.

[0049] Specifically, the multi-head crushing spiral teeth improve the crushing effect of the self-operated hydraulic breaker 33 on clumps and large molecular aggregates in waste liquid. The radial gap between the outer periphery of the multi-head crushing spiral teeth 331 and the inner wall of the crushing cavity 34 is 0.2-1mm to reduce negative leakage and ensure the rotational speed of the self-operated hydraulic breaker 33.

[0050] According to some embodiments of the present invention, the first inlet is connected to the gas control valve 5, and the second inlet is connected to the waste liquid control valve 4. Both the gas control valve 5 and the waste liquid control valve 4 are pneumatically or electrically driven, and the gas control valve 5 and the waste liquid control valve 4 form an interlocking relationship.

[0051] Specifically, interlocking is a common mechanical safety principle in automation systems. It enforces various relationships between the two devices during operation and control, maintaining a safe state. An interlocking relationship is formed between the gas control valve 5 and the waste liquid control valve 4. Adjusting the flow rate ratio ensures precise coordination of the flow rate of the breaker gas and waste liquid, thereby driving the self-propelled hydraulic breaker 33, achieving automated control, and reducing operational difficulty.

[0052] Understandably, the waste liquid control valve 4 and the gas control valve 5 are set with flow ratio regulation interlock automatic stabilization control. With the assistance of the crushing gas, waste liquid of any flow rate can achieve stable crushing and atomization spraying effect through the crushing spray head 3. This achieves automation, reduces the intensity of operation, and ensures the stability of the distribution device, effectively avoiding the problem of blockage in the distribution device.

[0053] The present invention also proposes a carbon-containing material conversion and reforming reactor, including a reactor 6, wherein the reactor 6 is provided with a liquid distribution device.

[0054] Reference Figure 1As shown in the diagram, specifically, by setting up a liquid distribution device in the reactor 6, the waste liquid enters the feed pipe 1 after the flow rate is regulated by the waste liquid control valve 4, and the crushing gas enters the feed pipe 1 after the flow rate is regulated by the gas control valve 5. The high-salt wastewater and the crushing gas are mixed in the feed pipe 1 and then enter the distribution pipe 2. The mixture of high-salt wastewater and crushing gas is distributed into the crushing nozzle 3 through the distribution pipe 2. The high-speed rotating self-powered crushing hammer 33 in the crushing nozzle 3 breaks and disintegrates the waste liquid droplets or large molecular aggregates and then atomizes and distributes them into the reactor 6. The atomized high-salt wastewater and the product gas flowing from bottom to top and the carbon-containing particles flowing from top to bottom in the reactor 6 are fully mixed and contacted. The lighter components in the waste liquid, such as water and light oil, are rapidly heated and flashed away by the product gas and sent out from the top of the reactor 6 with the product gas. Impurities dissolved in the waste liquid are adhered to and adsorbed by carbon-containing particles, and enter the high-temperature zone from top to bottom with the carbon-containing particle material layer to participate in the reforming and conversion reaction. Harmful components are decomposed and melted, and finally discharged from the bottom of the reactor for quenching and solidification, thereby improving the efficiency of the reforming and conversion reaction.

[0055] Understandably, the atomized waste liquid comes into full contact with and mixes with the product gas rising from the bottom. The product gas is cooled down, and the dust particles carried in the product gas are rapidly humidified, agglomerated, and grow. Under their own gravity, they return to the carbon-containing particulate material layer and enter the high-temperature zone from top to bottom with the carbon-containing particulate material layer to participate in the reforming and conversion reaction.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
