Description

Technical Field

[0001] The utility model relates to a low-energy-consumption and high-efficiency separator. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation, including plate-type and packed-type distillation towers. It utilizes the different volatilities of components in a mixture—that is, the different vapor pressures of each component at the same temperature—to transfer light components (lower boiling points) from the liquid phase to the vapor phase, while heavy components (higher boiling points) from the vapor phase transfer to the liquid phase, thereby achieving separation. For example, patent application number CN201520406063.7 describes a continuous distillation tower with stepped staggered trays. Plate-type distillation towers rely on contact on the trays under a gravitational field, requiring dozens of trays to achieve high-purity separations, resulting in low mass transfer efficiency and long processing time. The equipment is also relatively large and cumbersome, with the spacing between trays reaching tens of meters, requiring a large footprint. Unlike traditional distillation towers, this application utilizes centrifugal force to divide the liquid, creating a much larger surface area than the distillation tower, enabling more efficient mass transfer and chemical reactions. It takes up less space and achieves the same or better effect and rate as the distillation tower, which can achieve the purpose efficiently and save costs. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the purpose of this utility model is to provide a low-energy consumption and high-efficiency separator that can solve the problems of low efficiency, long time and large footprint of traditional distillation towers. At the same time, it also improves the mass transfer reaction efficiency through the setting of a liquid distributor, avoiding the local dry area of ​​the moving disk that leads to a reduction in mass transfer area and a decrease in efficiency.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a low-energy-consumption and high-efficiency separator, comprising a bracket, a shell and a driving mechanism being provided on the bracket, a plurality of groups of baffled rotors being vertically provided in the shell, the baffled rotors comprising a static plate connected to the shell and a dynamic plate connected to the driving mechanism, a downwardly recessed conical guide area being provided in the middle of the static plate, a liquid distributor being connected to the bottom of the conical guide area, and the liquid being evenly distributed through the liquid distributor and falling into the dynamic plate.

[0005] Furthermore, the conical guide area is circumferentially provided with a plurality of oblique grooves, and a liquid distributor is installed at the oblique grooves. The liquid distributor includes an annular collecting trough, and an oblique guide plate is abutted against the oblique groove on the outer edge of the upper end of the annular collecting trough corresponding to the oblique groove. A plurality of independent diversion troughs are provided on the lower layer of the annular collecting trough, and a guide pipe is provided between the annular collecting trough and the diversion trough. A drainage hole and a diversion plate are provided on the outer side wall of the diversion trough, and a plurality of curved arc-shaped guide plates arranged at circumferential intervals are distributed on the diversion plate inclined plate.

[0006] Furthermore, a plurality of hooks are provided on the inner side wall of the upper end of the annular collecting trough, and a filter screen is provided between the hooks.

[0007] Furthermore, the moving disk includes a base disk connected to the driving mechanism, and a connecting plate is detachably connected to the base disk. The connecting plate is provided with a plurality of concentric moving rings of different diameters. The static disk is provided with a plurality of concentric static rings of different diameters, and gaps are left between adjacent concentric static rings to accommodate the concentric moving rings. The concentric static rings and the concentric moving rings are nested with each other and arranged in an interlaced manner to form a channel for the circulation of gas and liquid.

[0008] Furthermore, the upper portions of the side walls of the plurality of concentric moving coils are circumferentially distributed with a plurality of oblique holes, and the oblique holes are arranged obliquely upward from the inner side to the outer side of the concentric moving coils.

[0009] Furthermore, the shell includes a top cover, a plurality of intermediate shells and a bottom shell, and the top cover, the bottom shell and the plurality of intermediate shells are fixedly connected by bolts.

[0010] Furthermore, the top cover is provided with an air outlet and a liquid return port, part of the middle shell is provided with a liquid inlet, and the bottom shell is provided with a liquid outlet and an air inlet, and the air outlet, liquid return port, liquid inlet, liquid outlet and air inlet are all connected to the interior of the shell.

[0011] Furthermore, the driving mechanism includes a main shaft and a motor. One end of the main shaft passes through the shell and is connected to the top cover through a bearing, and the other end is connected to a pulley, and the pulley is driven by a motor belt.

[0012] Beneficial effects: 1. Compared with traditional distillation towers, the high-efficiency separator in this application has high separation effect, small equipment size and low energy consumption. It can be combined with other reactors, evaporators and other equipment in the generation workshop to directly separate and purify the solvent, thereby optimizing the process flow, reducing energy consumption, saving costs and facilitating operation.

[0013] 2. This application sets a liquid distributor at the center of the static plate. The setting of the liquid distributor eliminates the deviation of the natural flow of the liquid, ensures that the moving plate receives the liquid evenly, increases the contact area with other phases, improves the mass transfer reaction efficiency, and avoids the local dry area of ​​the moving plate causing a reduction in mass transfer area and a decrease in efficiency.

The upper and lower ends of the stator plate 5 have corresponding slots with corresponding blocks. The extension platform also has blocks, and the upper and lower ends of the stator plate 5 have corresponding slots with corresponding blocks. These blocks and slots further restrict radial rotation of the stator plate 5, ensuring a secure and stable connection between the stator plate 5 and the housing 2. A downwardly concave conical guide area 7 is provided in the middle of the static disk 5. A liquid distributor 8 is connected to the bottom of the conical guide area 7. The liquid is evenly distributed and falls onto the dynamic disk 6 through the liquid distributor 8. A plurality of oblique grooves 9 are provided on the circumference of the conical guide area 7. The liquid distributor 8 is installed at the oblique groove 9. The liquid distributor 8 includes an annular collecting groove 11.
