Description

Technical Field

[0001] The utility model relates to the technical field of rectification preparation of deuterium-depleted water, in particular to a filling device for rectification. Background Art

[0002] Deuterium-depleted water with a low deuterium content is called light hydrogen molecular water, also known as ultra-light water.

[0003] According to a low-deuterium water preparation device disclosed in Chinese patent number CN 209685304 U, the device comprises a pure water storage tank, a distillation tower, a heating pump, a low-deuterium water collection tank and a high-deuterium water collection tank, wherein the distillation tower comprises a feed section, a reboiling section, a rectifying section and a discharge section from bottom to top, a reboiler is installed in the reboiling section, a high-deuterium water discharge port is arranged on the side of the reboiling section, the high-deuterium water discharge port is connected to the high-deuterium water collection tank, a tower plate and a packing are arranged in the rectifying section, the discharge section is connected to the low-deuterium water collection tank, the heating pump is connected to the feed section, a heat exchange pipe is arranged between the pure water storage tank and the distillation tower, and the water source in the pure water storage tank enters the distillation tower after being preheated by the heat exchange pipe. The device makes full use of the waste heat in the distillation process to preheat the raw water, thereby ensuring the output and quality of low-deuterium water within a relatively low tower height range, reducing energy consumption, effectively shortening the preparation time of low-deuterium water, and improving production efficiency.

[0004] The distillation tower in the deuterium-depleted water preparation device in the prior art is equipped with a special packing structure. The main function of the existing packing structure packing is to increase the reaction area and conversion rate and improve the reaction efficiency. The packing can increase the contact area between substances, increase the reaction rate and improve the reaction efficiency, while reducing energy consumption and reducing pollution. However, in actual use, there are the following problems: 1. The droplets on the surface of the existing packing are unevenly distributed, and the droplets will quickly remix, reducing the contact mass transfer efficiency. Secondly, the pores on the surface of the packing are easily blocked by bubbles, affecting the contact mass transfer, so a packing device for distillation is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a filling device for distillation.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a filling device for distillation, comprising a mesh frame, side blocks are provided on both sides of the mesh frame, a top card is clamped on the top of the mesh frame, arc plates are embedded on both sides of the top of the top card, detection probes are installed on the top of the arc plates, electric push rods are connected to the outer sides of the arc plates, side columns are installed on the outer ends of the electric push rods, and cones are threadedly connected to the outer sides of the side columns.

[0007] Preferably, a mass transfer hole is provided at the top of the top clamping plate near the outer side of the arc plate, and a flip cover is clamped on one side of the top of the mass transfer hole.

[0008] Preferably, a lower inclined plate is clamped at the bottom of the inner part of the screen frame near the top clamping plate, and the lower inclined plate is inclined to one side, with gaps left between the lower inclined plates.

[0009] Preferably, a middle supporting plate is clamped in the middle of the mesh frame, and a rectangular array of filter holes is provided on the top of the middle supporting plate.

[0010] Preferably, a square cone is embedded in the middle of the top end of the middle support plate, and the square cone is aligned with the gap area between the middle support plates on both sides.

[0011] Preferably, a welding plate is welded to the middle of the bottom end of the middle support plate, and filtering inclined plates are clamped on both sides of the welding plate.

[0012] Preferably, the filter inclined plate is inclined to one side, and a filter sieve hole is provided on the top of the filter inclined plate.

[0013] Beneficial Effects

[0014] In the utility model, a new type of packing component is mainly provided. First, the whole packing component is spliced ​​together by multiple mesh frames. The arc plate on the top of the top card plate is made of high temperature resistant material. The detection probe on the top is an airtight detector for detecting whether there are bubbles in the mass transfer holes. When bubbles are detected in the mass transfer holes, a command signal is transmitted to the electric cylinder component in the arc plate through the built-in MCU. After receiving the signal, the electric cylinder component controls the electric push rod to push outward. When the electric push rod is pushed outward, it drives the outer side column to push forward. When the side column is pushed outward, it punctures the bubbles in the mass transfer holes through the piercing cone.

[0015] The droplets will fall from the middle gap in the middle and directly contact and collide with the square cone, which will break the contacted droplets, and then the broken droplets will fall onto the middle supporting plates on both sides respectively, and then the broken droplets will fall from the filter holes, which will filter out some impurities in the liquid. After falling, the back mixing will not occur due to the shielding of the welding plate. The broken droplets on both sides will fall onto the filter inclined plates on both sides respectively, and then leak out from the openings of the inclined plates. The attached figure shows a single group of packing structures, and the attached figure shows the internal structure of the mesh frame. During normal use and assembly, the five-row packing structure is regarded as a whole. During actual use, the dropped droplets will pass through five layers of the same structure, and the droplets will continue to become smaller, the contact surface will be wider, and the back mixing phenomenon will be reduced.
