Description

[0001] Apparatus for manufacturing high-purity distilled water [0002]

The present invention relates to an apparatus for producing distilled water, and more particularly, to a system and method for preventing the mixing of purified water and non-purified water in a housing during the process of producing distilled water by vaporizing feed water passing through a housing of a distillation column, And more particularly, to a distilled water producing apparatus with improved structure for allowing external air to pass through to improve condensation efficiency.

Generally, the distilled water production facility is to produce desired distilled water by cooling and condensing the saturated steam produced by heating the raw water (raw water, hereinafter referred to as supply water) for producing distilled water, by heat exchange, It is practically used in various industrial fields, and its structure and form are very diverse.

The manufacturing principle of such a conventional distilled water production facility is that the supply water is heated by the heating means while supplying the feed water to the distillation means, and when the saturated steam is generated from the feed water by the heating, the saturated steam is heat- And condensed in the process to produce distilled water.

Pure distillation equipment is being replaced by reverse osmosis equipment due to the difficulty in maintaining the quality of water continuously, but it has been universally used in some fields including pharmaceuticals to date.

For example, Korean Patent Registration No. 0162749 entitled "Distilled Water and Ultrapure Water Production Apparatus" has a structure in which distilled water or ultrapure water is selectively discharged through a valve by operating a button on one side of a case, and an evaporator is installed inside the case And a distilled water pump and an ultrapure water pump are installed on the side of the evaporator and the ultrapure water pump is installed in a multi-stage manner. A carbon filter, an ion cartridge, and a final filter, in order to produce ultrapure water while passing distilled water.

It mainly produces distilled water or ultra pure water which can be used for various purposes such as laboratory, microbial cultivation, chemical experiment and semiconductor washing, and it is expected that the installation space can be reduced so that it can be reasonably used even in a relatively small space. However, according to this method, since it is used in a laboratory, mass productivity is insufficient and it is difficult to maintain high purity for medicines.

As another example, as disclosed in Korean Patent Publication No. 10-0243518, entitled " Distillation Apparatus for Producing High-purity Distilled Water "(Registered on November 16, 1999), the applicant of the present application, Wherein the first distillation tower is provided with a first distillation tower through which the feed water flows, the feed water introduced into the first distillation tower is heated by an external heat source (steam) passing through the heat source accommodation space, The supply water which is supplied to the heat source accommodation space of the heat source and is not evaporated during the heat exchange process is circulated back to the second distillation tower (not shown), and finally the heat source vapor and the condensed water collected in the heat source accommodation space And the steam evaporated by the heat source vapor is cooled to produce distilled water.

This is expected to produce the effect of producing highly purified distilled water in which impurities and foreign substances are minimized by the multi-stage refining process of the feed water.

At this time, as the feed water is vaporized while passing through the heat source accommodation space, the steam is refluxed through the heat exchange upward pipe, and the feed water is collected in the non-distilled feed water collection container.

In this case, as shown in FIG. 6, since the untreated distilled water collector 113 and the cyclone refiner 120 are connected to each other, when distilled water and purified water are mixed before purified, The purity is lowered.

Further, since the housing 100 is formed of a cylindrical structure that is sealed with a heat insulating material, there is a disadvantage in that the condensing efficiency of the vapor vaporized by the heat source decreases while passing through the housing 100.

Accordingly, it is difficult to maintain the initial purity when the production amount is increased according to the fluctuation of the mass production demand, and in order to improve the purity, there is a drawback in that the production amount must be lowered.

Korean Registered Utility Model No. 0162749 entitled "Distilled Water and Ultrapure Water Production Apparatus" Korean Patent Registration No. 10-0243518 entitled "Distillation Apparatus for Producing Highly Purified Distilled Water" (registered on November 16, 1999)

In the present invention having such a configuration, the supply water drawn into the first distillation column (C1) from the water tank (W / T) through the feed water line (106) flows through the heat source accommodating space (104) The supply water and the steam heated and evaporated by the external heat source are heated (about 135 to 140 degrees Celsius) by the supply water line ST and the supply water and the steam are supplied through the supply water return line 112 between the sealing plate 111 and the nozzle plate 109 Is supplied to the pressure space 115 of the nozzle plate 109 and is injected through the tube hole 108 of the nozzle plate 109 of the nozzle plate 109 while being heat exchanged by the external heat source ST, .

In this forced downward feed water and steam, the evaporated steam is refluxed through the central heat exchange upflow pipe 107, and the feed water (un-distilled) (113).

At this time, the steam is passed through the cyclone refining apparatus 120. Specifically, the steam is moved upward through the space of the heat exchange upstream pipe 107 and the outer pipe 122, And then moves upward through the inner tube 121 to generate a swirling flow along the spiral 124 formed between the inner tube 121 and the inner tube 121 via the inner tube 121, The supply water (unmistillation supply water) supplied to the heat source accommodation space 104 of the column C2 and provided as a heat source at the same time and not evaporated flows through the second distillation column C2 through the supply water return line 112, The pressure is supplied to the pressure space 115 between the sealing plate 111 and the nozzle plate 109 as described above so that the pressure in the tube tube 108 is increased through the nozzle hole 110 of the nozzle plate 109, ), And the heat source Ten won for steam and heat within the space 104 acts to the heat source and the steam can be supplied is achieved As the mutual condensation and evaporation is forced to repeat the process down.

The vaporized steam is returned through the central heat exchange upstream pipe 107 to the distillation supply water collection tube 113 at the lower portion of the housing 100. The distillation water is supplied to the distillation supply water collection tube 113, In the process.

The condensed water generated in the heat source vapor during the heat exchange process is supplied to the heat source accommodation space 104 of the third distillation column C3 by the condensate water return line 116, And heat exchange with the heat source vapor in the heat source accommodation space 104 is performed.

The feed water flowing into the first distillation column C1 from the last distillation column C8 gradually warms up to the final distillation column C8 until the heating energy of the external heat source ST And ultimately, the heat source vapor and the condensed water collected in the heat source accommodation space 104 of the last distillation column C8 and the vapor evaporated by the heat source vapor are cooled to produce distilled water purified with high purity.

At this time, the feed water drawn into each of the distillation columns C1 to C8 is sprayed downward from the upper part to the lower part through the tube pipe 108 while being heated, and reheated by the external heat source ST or the heat source steam A first purification process is performed in which steam is generated in the lower part of the distillation columns C1 to C8 and the impurities and impurities contained in the feed water are separated and the generated steam is further raised and lowered by the cyclone purifying mechanism 120 During the process of descending and ascending, evaporation and condensation are carried out in the course of the second purification process of separating impurities and impurities contained in the generated steam.

At this time, in the first purification process, the tube tubes 108 and 106 are shown as straight tubes in the drawing, but in order to increase the purification efficiency, the tube tubes 108 and 106 serve as spiral tubes, The secondary purification process may also be performed by using a downward spiral structure formed between the inner pipe 121 and the wiper pipe 122 constituting the cyclone refining apparatus 120, The steam generated by the steam generator 124 is circulated by the steam generator 124, and the steam and the impurities contained in the steam are separated to evaporate and condense the purified steam.

Pure steam generated through the first and second purification steps rises and pure steam is supplied to the heat source accommodation space 104 of the next distillation columns C2 to C8 to perform a heat source function.

Accordingly, it is possible to produce purified water of high purity in which impurities and foreign substances are minimized by the multi-step purification process of the feed water and the repetitive purification process of the multi-step purification process.

When the distilled water condensed during the purification process of the feed water is supplied to each of the heat source accommodation spaces 104 of the subsequent distillation columns C1 to C8, the sampling is collected on the condensate water return line 116 so that the sampled distilled water is required Distilled water requirements In other words, if the purification requirements are met, it can be recovered during the continuous distillation process and used through the cooling process at the required temperature.

The heat source vapor and the condensed water collected in the heat source accommodation space 104 of the last distillation column C8 and the pure steam evaporated by the heat source vapor are supplied to the first heat exchanger 200 through the heat exchanger 200, The distilled water having a necessary temperature (about 97 degrees Celsius) is condensed and produced by heat exchange with the feed water of the water line 106. When the temperature of the final distilled water is required to be the temperature below the above temperature, It is possible to produce distilled water at a required temperature by means of the secondary heat exchanging means 300 through the secondary heat exchanging means 300.

The upper flange 102 and the lower flange 103 are spaced apart from each other on the upper and lower sides of the housing 100 and the inner peripheral surface of the upper flange 102 and the lower flange 103 are spaced apart from the outer peripheral surface of the heat exchange upward pipe 107, The upper and lower flanges 102 and 103 and the upper and lower gaps of the housing 100 to the inside of the center of the housing 100 to be circulated.

Therefore, the present invention can be applied to the case where outside air flows into the first and second supply passages 100b and 100c between the upper and lower flanges 102 and 103 spaced from the upper and lower sides of the housing 100, Since the structure in which the outside air flows into the clearance space between the outer circumferential surface and the inner circumferential surface of the housing 100 and is circulated, the condensing efficiency of the steam passing through the inside of the heat exchanging upturning tube 107 can be improved.

In addition, since the purified water discharge line 127 is extended from the lower portion of the cyclone refining device 120 and is exposed to the outside through the distillation supply water collection tube 113, the cyclone refining device 120 Purified water is discharged directly to the outside without being mixed with the supply water collected in the distillation-fed-water collection tube 113, so that the purified water of high purity can be obtained.

The present invention is characterized in that a plurality of grooves 107a are formed on the outer circumferential surface of the heat exchange upstream pipe 107 to serve as circulation passages for the outside air and the spiral grooves 100a are formed on the inner circumferential surface of the housing 100, The efficiency of condensing of the steam passing through the heat exchange upward pipe 107 with respect to the outside air can be improved as the steam is circulated smoothly into the clearance space between the inner circumferential surface of the housing 100 and the outer circumferential surface of the heat exchange upward pipe 107 .
