Description

Technical Field

[0001] This utility model relates to the field of high vacuum distillation tower technology, specifically a liquid distribution device for a high vacuum distillation tower. Background Technology

[0002] The liquid distribution device of the high vacuum distillation column can achieve initial, highly uniform liquid distribution across the entire column cross-section under extremely low liquid load, while the pressure drop must be extremely low to achieve precise and uniform liquid distribution, thus meeting the challenges of low load and high gas velocity.

[0003] Existing liquid distributors use nozzles or orifice plates to force liquid through, forming uniform small droplets that are then sprayed onto the packing layer below. However, the fixed installation positions of the nozzles and the opening positions of the orifice plates prevent convenient adjustments based on different production needs, resulting in poor overall applicability of the device. Therefore, a liquid distribution device for a high-vacuum distillation tower needs to be designed to address these issues. Utility Model Content

[0009] By adopting the above technical solution, dense droplet spraying is achieved through the combination of central and side distribution nozzles.

[0010] In a preferred embodiment of the liquid distribution device for the high vacuum distillation tower of this utility model, the corrugated pipe and the side distribution pipe are alternately distributed, and the top surface of the side distribution pipe is attached to the bottom surface of the substrate.

[0011] By adopting the above technical solution, the horizontal spacing of the side distribution pipes is adjusted by horizontally moving the side distribution pipes to squeeze or stretch the corrugated pipes, thereby changing the working position of the side distribution nozzles.

[0015] By adopting the above technical solution, the working position of the side distribution pipe and the side distribution nozzle can be adjusted by sliding the positioning bolts in a straight line along the track groove.

[0016] Beneficial effects This invention provides a liquid distribution device for a high-vacuum distillation column. It has the following advantages: 1.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a liquid distribution device for a high-vacuum distillation tower. It includes a central distribution pipe 1 with a central distribution nozzle 2 installed at its bottom end, a top connecting pipe 3 fixed at the top center of the central distribution pipe 1, the top of the top connecting pipe 3 connected to the bottom end of a filter mechanism 4, the top of the filter mechanism 4 connected to a positioning plate 5, an inlet pipe 6 fixed at the center of the positioning plate 5, a side connecting pipe 7 fixed to the side of the central distribution pipe 1, the side connecting pipe 7 connected to a distribution mechanism 8, and a positioning mechanism 9 provided at the top of the distribution mechanism 8, which is connected to the top of the outer wall of the central distribution pipe 1. The filter mechanism 4 includes a filter cylinder 401 vertically installed between the top of the top connecting pipe 3 and the bottom of the positioning plate 5, with a filter screen 402 fixed inside the filter cylinder 401. The distribution mechanism 8 includes a corrugated pipe 801 horizontally installed at the end of the side connecting pipe 7, a side distribution pipe 802 installed at the end of the corrugated pipe 801, and a side distribution nozzle 803 installed at the bottom end of the side distribution pipe 802.

[0021] Specifically, the front view cross-sectional shape of the filter cartridge 401 is "I" shaped. Filter screens 402 are fixed at equal intervals on the inner wall of the filter cartridge 401. The center distribution nozzles 2 are distributed at equal intervals at the bottom end of the top connecting pipe 3. The center of the center distribution nozzles 2 and the center of the side distribution nozzles 803 are on the same vertical plane. The corrugated pipes 801 and the side distribution pipes 802 are alternately distributed. The top surface of the side distribution pipes 802 is attached to the bottom surface of the substrate 904. The filter cartridge 401 and filter screen 402 further filter the liquid, and together with the center distribution nozzle 2 and the side distribution nozzle 803, the liquid is smoothly dispersed.

[0022] Example 2 Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The positioning mechanism 9 includes a base plate 904 that is horizontally fixed to the top of the outer wall of the central distribution pipe 1. A track groove 903 is provided on the base plate 904.

[0023] Specifically, a positioning bolt 901 is fixed in the middle of the top surface of the side distribution pipe 802, and a positioning nut 902 is installed on the positioning bolt 901. The positioning bolt 901 passes through the track groove 903, and the positioning bolt 901 and the track groove 903 are slidably connected. The center of the positioning bolt 901 and the center of the base plate 904 are on the same vertical plane, and the base plate 904 is symmetrically distributed about the center of the central distribution pipe 1. Furthermore, by sliding the side distribution pipe 802 with the positioning bolt 901 horizontally along the track groove 903, the working position of the side distribution nozzle 803 can be adjusted to adapt to different production needs.

[0024] Working principle: During installation and debugging, screw the positioning nut 902 on top, push the positioning bolt 901 to slide the side distribution tube 802 horizontally along the track groove 903 for adjustment. When the side distribution tube 802 moves horizontally, it stretches or compresses the corrugated tube 801 until the distance between the adjacent side distribution nozzles 803 is appropriate. Then screw the positioning nut 902 down to press the top surface of the base plate 904 to fix the position of the side distribution tube 802 and the side distribution nozzles 803. During operation, the liquid enters the filter cartridge 401 through the inlet pipe 6, the filter screen 402 traps impurities, and finally the liquid is discharged downward through the center distribution nozzle 2 and the side distribution nozzle 803, achieving uniform liquid distribution. This is the working principle of the liquid distribution device of the high vacuum distillation tower.
