Description

Technical Field

[0001] This invention belongs to the field of chemical process and energy recovery technology, specifically relating to a reactor system that utilizes a turbine flow channel for efficient multi-layer stirring. Background Technology

[0002] Against the backdrop of current global climate change and environmental protection, the fields of chemical processes and energy recovery face a series of challenges and problems. Traditional stirred reactors have high energy consumption and low mixing efficiency, resulting in insufficient and uneven mixing, which leads to insufficient reaction efficiency and resource utilization, causing resource waste.

[0003] To address the aforementioned problems, this invention provides a reactor system employing a turbine flow channel for efficient multi-layer stirring. The three-layer stirring reaction system promotes mixing and mass transfer during the reaction process, thereby improving reaction rate and uniformity. Furthermore, the loop system enables simultaneous reaction and stirring processes, enhancing both reaction efficiency and mixing efficiency. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, the present invention aims to provide a reactor system for efficient multi-layer stirring using a turbine flow channel. This reactor system has significant application value and technological advantages in solving problems such as low mixing efficiency and energy waste in traditional chemical stirring processes. It can achieve highly efficient stirring and mixing reactions, greatly improving the uniformity of the stirring reaction. It can be practically applied in fields such as chemical, energy, and pharmaceutical equipment. For liquid-liquid extraction reactions, the solute transfer process between liquids can be optimized through the turbine flow channel, thereby improving separation and purification efficiency.

[0005] This invention provides the following technical solution: a reactor system for efficient multi-layer stirring using a turbine flow channel, comprising a three-layer stirring reaction system and a loop system. The three-layer stirring reaction system includes a stirred tank body, within which three layers of stirring reaction spaces are arranged sequentially from top to bottom. A filter screen is arranged between adjacent stirring reaction spaces. A rotatable stirring shaft is arranged in the stirred tank body, passing through the three layers of stirring reaction spaces from top to bottom. An impeller, stirring blades, and a single-cone spiral ribbon are respectively arranged on the shaft in the three layers of stirring reaction spaces. The upper stirring reaction space is provided with a flow channel structure with gradually decreasing size.

[0006] The circuit system includes a feed pipe and a discharge pipe connected to the bottom outlet of the mixing vessel body. A hydraulic screw conveyor is installed on the mixing vessel body. The discharge end of the hydraulic screw conveyor is connected to the interior of the mixing vessel body. The hydraulic screw conveyor has two feed ends, which are connected to the feed pipe and the discharge pipe respectively, forming a feed and discharge channel and realizing the return of materials.

[0007] Furthermore, a planetary reducer is provided on the stirring shaft below the impeller to ensure that while the impeller rotates at high speed, a lower stirring speed is transmitted to the stirring blades.

[0008] Furthermore, the planetary reducer is placed on the upper filter screen plate and is coaxially arranged with the stirring shaft.

[0009] Furthermore, a frustum-shaped shell coaxial with the stirring shaft is provided in the upper stirring reaction space, with the smaller end facing downwards, forming a flow channel structure with gradually decreasing size.

[0010] Furthermore, the main body of the stirred tank is in the form of a conical cylinder located in the lower stirring reaction space.

[0011] Furthermore, the dimensions of the structures located in the upper and middle stirring reaction spaces on the main body of the stirred tank are the same. After the material flows through the upper stirring reaction space where the flow channel gradually narrows, it is introduced into the middle stirring reaction space where the flow channel expands based on the Venturi effect.

[0012] Furthermore, the discharge pipe is connected to the feed end of the hydraulic screw conveyor via a pressure pipe, which is equipped with a check valve, a flow meter, and a filter.

[0013] Furthermore, the filter screen between two adjacent layers of stirring reaction space is coaxially arranged with the stirring shaft.

[0014] By employing the above-described technology, the beneficial effects of the present invention compared to the prior art are as follows:

[0015] 1) High-efficiency reaction performance: The present invention adopts a three-layer stirring reaction space. The first layer stirring space is based on the setting of a hydraulic screw conveyor, which uses its turbine flow channel to pressurize the feed and increase the kinetic energy of the feed. The high-speed rotation of the impeller realizes the mixing reaction of the feed, achieving higher reaction efficiency and mixing uniformity, and improving the production efficiency of the reactor.

[0016] 2) Special stirring performance: In this invention, the flow channels in the first layer of stirring reaction space gradually shrink, while the flow channels in the second layer of stirring reaction space expand. In accordance with the principle of the Venturi ejector device, a negative pressure is created at the connection between the layers, which introduces the liquid phase fluid into the second layer of the reaction device, thereby achieving accelerated flow of the liquid phase and promoting the desired reaction.

[0017] 3) Reflux reaction performance: The inlet end of the loop system of this invention is connected to the outlet end of the stirred tank, and the outlet end is connected to the hydraulic screw conveyor at the inlet end of the stirred tank. The unreacted material is refluxed back into the stirred tank to continue the stirring reaction, so as to achieve full mixing of the material, enhance the uniformity of the mixing of the stirred material, improve production efficiency and product quality, and meet the requirements of sustainable development.

Furthermore, to provide a better understanding of the invention, certain specific details are described in detail below. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0023] For examples, please refer to Figure 1-3 This embodiment provides a highly efficient and green multilayer reactor system that integrates liquid-liquid mixing and stirring, comprising a three-layer stirring reaction system 1 and a loop system 2. The three-layer stirring reaction system promotes mixing and mass transfer in the reaction process, improving the reaction rate and uniformity; the loop system enables the reaction and stirring processes to proceed simultaneously, improving reaction efficiency and mixing uniformity.

[0024] Specifically, the three-layer stirred reaction system 1 is the main structure in which the liquid phase fluid participates in the reaction, including the stirred tank body 101, the hydraulic screw conveyor 102, the motor 103, the stirring shaft 104, the impeller 105, the planetary reducer 106, the stirring blades 107, the filter screen plate 108, and the single conical ribbon 109.

[0025] The interior of the stirred tank body 101 is divided into three layers of stirring reaction space from top to bottom by two filter screen plates 108; wherein, the upper and middle stirring reaction spaces of the stirred tank body 101 are cylindrical structures, and the lower stirring reaction space is a conical structure.

[0026] The hydraulic screw 102 is installed on the upper part of the mixing vessel body 101, and the fluid enters the mixing vessel body 101 through the internal turbine-type flow channel.

[0027] The motor 103 is located on the top of the stirred tank body 101, and its output end is connected to the stirring shaft 104; the stirring shaft 104 is set through the three-layer stirring reaction space.

[0028] Impeller 105 is mounted on stirring shaft 104 and is located in the upper stirring reaction space.

[0029] The planetary reducer 106 is placed on the filter screen plate 108 and is coaxially arranged with the stirring shaft 104.

[0030] The stirring blades 107 and the single-cone spiral ribbon 109 are both mounted on the stirring shaft 104 and are located in the middle stirring reaction space and the lower stirring reaction space, respectively.

[0031] The filter screen plate 108 is concentric with the stirring shaft 104.

[0032] The upper stirring reaction space is provided with a frustum-shaped shell 110 coaxial with the stirring shaft 104, with the smaller end facing downwards, forming a flow channel structure with gradually decreasing size.

[0033] Specifically, the loop system 2 includes an inlet 201, an outlet pipe 202, a check valve 203, a flow meter 204, a pressure pipe 205, and a filter 206.

[0034] The feed inlet 201 is connected to the inlet of the hydraulic screw conveyor 102, the discharge pipe 202 is connected to the bottom of the mixing tank body 101, the one-way valve 203 is connected to the discharge pipe 202, the flow meter 204 is connected to the one-way valve 203 through the pressure pipe 205, the filter 206 is connected to the flow meter 204 through the pressure pipe 205, and finally the outlet end is connected to the inlet end of the hydraulic screw conveyor 102.

[0035] The working principle of the system in this embodiment is as follows:

[0036] Through the hydraulic screw conveyor 102, the material enters the upper stirring reaction space through the turbine-type flow channel inside the hydraulic screw conveyor 102, thereby increasing the pressure and kinetic energy of the liquid phase fluid. The impeller 105 rotates rapidly, driving the liquid phase fluid to move rapidly, thus improving the reaction efficiency. A planetary reducer 106 is installed below the impeller 105. Using its gear speed converter, the high-speed rotating impeller 105 is decelerated and transmitted to the stirring blades 107 in the middle stirring reaction space.

[0037] In the upper stirred reaction space, the flow channel gradually narrows, while in the middle stirred reaction space, the flow channel expands. Following the principle of a Venturi ejector, liquid fluid is introduced into the middle stirred reaction space, and negative pressure accelerates the flow of the liquid phase, thereby promoting the desired reaction. The stirring blades 107 in the middle stirred reaction space and the single-cone spiral ribbon 109 in the lower stirred reaction space continue to drive the fluid in a stirred reaction, improving the material reaction efficiency.

[0038] In loop system 2, the feed inlet 201 is connected to one inlet end of the hydraulic screw conveyor 102. The unmixed liquid phase fluid flows out from the outlet of the stirred tank body 101, and is connected to the other inlet end of the hydraulic screw conveyor 102 via the discharge pipe 202 and the pressure pipe 205, and flows back into the stirred tank body 101 to continue the reaction, thereby improving the uniformity of material reaction and mixing.

[0039] In the loop system 2, the one-way valve 203 is used to control the flow of materials, the flow meter 204 is used to detect the flow rate of materials flowing through the pipeline, and the filter 206 is used to filter the materials flowing through the pipeline.

[0040] In this embodiment, in the first layer of the stirring reaction space, the turbine-type flow channel based on the hydraulic screw 102 realizes the pressurization of the feed, and the high-speed rotation of the impeller 105 realizes the mixing reaction of the feed; in the second layer of the stirring reaction space, the cylinder flow channel is enlarged in imitation of the Venturi ejector structure to realize the liquid phase acceleration, and the stirring reaction continues through the stirring blade 107; in the third layer of the stirring reaction space, the conical cylinder facilitates the discharge, and the single conical screw ribbon 109 continues to drive the material to carry out the stirring reaction.

[0041] Meanwhile, loop system 2 transports materials that have not been fully mixed and reacted to the feed end, improving the uniformity of the reaction.
