Description

Technical Field

[0001] This utility model relates to the field of distillation water machines, and in particular to a vapor-liquid separation device for a multi-effect rising film distillation water machine. Background Technology

[0002] In the pharmaceutical, electronics, and chemical industries, high-purity distilled water is a critical production factor. For example, water for injection must meet the stringent requirements of the Chinese Pharmacopoeia regarding microbial limits and endotoxins; in semiconductor chip manufacturing, ultrapure water is used to clean wafers to prevent impurities from affecting performance. Currently, mainstream distillation water technology includes multi-effect rising film distillation water systems.

[0003] Traditional multi-effect rising film distillation water machines heat purified water during use. This single heating method can easily lead to multiple processing steps, affecting work efficiency. Furthermore, while the purified water is rising, it is output as distilled water through a spiral separator. However, some impurities remain in the distilled water at this point, making it less pure. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that the traditional multi-effect rising film distillation water machine mentioned above or in the prior art heats the purified water during use, the single heating method easily leads to multiple processing steps, affecting work efficiency. Furthermore, the purified water is output as distilled water through a spiral separator during the rising process, but at this time, some impurities remain in the distilled water, making it not pure enough.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-effect rising film distillation water separator vapor-liquid separation device, comprising a distillation water separator body, including a purified water inlet pipe connected to the distillation water separator body, a steam input pipe disposed at the bottom of the purified water inlet pipe and connected to the distillation water separator body, a concentrated water outlet connected to the distillation water separator body, an evaporation chamber connected to the top of the distillation water separator body, and a water storage chamber connected to the bottom of the distillation water separator body; a heating unit, including a heating layer installed on the inner wall of the distillation water separator body, and a heating mechanism connected to the bottom of the heating layer; a filtration unit, including a first filtration plate installed on the inner wall of the distillation water separator body, a second filtration plate disposed on top of the first filtration plate, and a third filtration plate disposed on top of the second filtration plate; a steam outlet is provided at the top of the evaporation chamber, and a condensate water storage port is provided at the bottom of the water storage chamber.

[0007] Preferably, the heating mechanism includes a first mounting plate installed at the bottom of the heating layer, an evaporation tube that extends through and connects to the bottom of the first mounting plate, and a second mounting plate installed at the bottom of the evaporation tube.

[0008] Preferably, the first filter plate has circular holes arranged in a ring, and a first ceramic filter block is provided in the circular holes. The first ceramic filter block contains ceramic particles with a diameter of 0.8 mm.

[0009] Preferably, the second filter plate has circular holes arranged in a ring, and a second ceramic filter block is provided in the circular holes. The second ceramic filter block contains ceramic particles with a diameter of 0.6 mm.

[0010] Preferably, the third filter plate has circular holes arranged in a ring, and a third ceramic filter block is provided in the circular holes. The third ceramic filter block contains ceramic particles with a diameter of 0.4 mm.

[0011] Preferably, the purified water inlet pipe is L-shaped, and a sprayer is installed at the bottom of the purified water inlet pipe.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the heating unit of this utility model can heat the purified water once. Since the inner wall of the water storage chamber is equipped with a heating film, the formation of the rising film evaporation of purified water can be accelerated, thereby improving the efficiency of rising film evaporation. Furthermore, the filtration unit, with ceramic particles of different diameters in the first ceramic filter block, the second ceramic filter block, and the third ceramic filter block, filters the steam, thereby improving the purification degree of the steam.

[0018] The present invention will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] As shown in Figures 1-3, the system includes a water distiller body 1, comprising a purified water inlet pipe 101 connected to the water distiller body 1, a steam inlet pipe 102 located at the bottom of the purified water inlet pipe 101 and connected to the water distiller body 1, a concentrated water outlet 103 connected to the water distiller body 1, an evaporation chamber 104 connected to the top of the water distiller body 1, and a water storage chamber 105 connected to the bottom of the water distiller body 1; and a heating unit 2, comprising components installed at the bottom of the water distiller body 1. The water distiller body 1 includes a heating layer 201 on its inner wall and a heating mechanism 202 connected to the bottom of the heating layer 201; a filtration unit 3, comprising a first filtration plate 301 installed on the inner wall of the water distiller body 1, a second filtration plate 302 disposed on top of the first filtration plate 301, and a third filtration plate 303 disposed on top of the second filtration plate 302; a steam outlet 104a is provided at the top of the evaporation chamber 104, and a condensate storage port 105a is provided at the bottom of the water storage chamber 105. The concentrated water outlet 103 is in the opposite direction to the steam input pipe 102. A heating film is provided on the inner wall of the water storage chamber 105.

[0020] Specifically, the heating mechanism 202 includes a first mounting plate 202a installed at the bottom of the heating layer 201, an evaporation tube 202b extending through and connecting the bottom of the first mounting plate 202a, and a second mounting plate 202c installed at the bottom of the evaporation tube 202b. The top diameter of the heating layer 201 is larger than the bottom diameter.

[0021] Specifically, the first filter plate 301 has circular holes distributed in an annular manner, and a first ceramic filter block 301a is provided in the circular holes. The first ceramic filter block 301a contains ceramic particles with a diameter of 0.8 mm.

[0022] Specifically, the second filter plate 302 has circular holes distributed in an annular manner, and a second ceramic filter block 302a is provided in the circular holes. The second ceramic filter block 302a contains ceramic particles with a diameter of 0.6 mm.

[0023] Specifically, the third filter plate 303 has circular holes distributed in an annular pattern, and a third ceramic filter block 303a is provided in the circular holes. The third ceramic filter block 303a contains ceramic particles with a diameter of 0.4 mm.

[0024] Specifically, the purified water inlet pipe 101 is L-shaped, and a sprayer 101a is installed at the bottom of the purified water inlet pipe 101.

[0025] In use, purified water flows through the purified water inlet pipe 101 to the sprayer 101a, where it is atomized and sprayed. Simultaneously, industrial steam is introduced into the distillation water machine body 1 through the steam inlet pipe 102. A portion of the atomized purified water falls downwards due to gravity, contacting the surface of the heating layer 201, which then evaporates the purified water. Another portion flows downwards along the inner wall of the distillation water machine body 1, evaporating as it flows. The remaining purified water enters the evaporation pipe 2. Inside 02b, when purified water enters the evaporation tube 202b, falling film evaporation occurs. Part of the water evaporates, and the rest slides down into the water storage chamber 105. Since the inner wall of the water storage chamber 105 is equipped with a heating film, the formation of rising film evaporation of purified water can be accelerated, thereby improving the efficiency of rising film evaporation. Steam rises from the evaporation tube 202b and is filtered by ceramic particles of different diameters in the first ceramic filter block 301a, the second ceramic filter block 302a, and the third ceramic filter block 303a in the filtration unit 3, thereby improving the purification degree of the steam.

[0026] In summary, through the setting of heating unit 2, heating layer 201 can heat purified water once. Since the inner wall of water storage chamber 105 is equipped with a heating film, the formation of purified water rising film evaporation can be accelerated, improving the efficiency of rising film evaporation. Furthermore, the setting of filtration unit 3, with ceramic particles of different diameters in the first ceramic filter block 301a, the second ceramic filter block 302a, and the third ceramic filter block 303a, filters the steam, thereby improving the purification degree of the steam. This effectively solves the problem that traditional multi-effect rising film distillation water machines, when used, heat purified water by a single heating method, which easily leads to multiple processing and affects work efficiency. Moreover, when purified water rises, it is output as distilled water through a spiral separator, but at this time, some impurities remain in the distilled water, making it not pure enough.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
