Description
本發明是關於將不同種類的離子交換樹脂(例如，陰離子交換樹脂與陽離子交換樹脂)平均且保持清淨度的狀態下作混合的方法。 The present invention relates to a method of mixing different types of ion exchange resins (for example, an anion exchange resin and a cation exchange resin) while maintaining a cleanness.
以往離子交換樹脂的混合方法，是藉著使混合槽內之離子交換樹脂及水以氣體或空氣作起泡攪拌而產生流動以混合的方法(特開平7-116526)。 In the conventional method of mixing an ion exchange resin, a method in which an ion exchange resin and water in a mixing tank are stirred by a gas or air to cause a flow to be mixed (Japanese Patent Laid-Open No. Hei 7-116526).

[專利文獻3]特開2011-11120 [Patent Document 3] Special Opening 2011-11120
專利文獻1之離子交換樹脂的混合方法，因為會有大氣中的塵埃或微粒子混入混合工程內的疑慮，並不是很適用於用來製作高清淨度的離子交換裝置。 The method of mixing the ion exchange resin of Patent Document 1 is not suitable for use in an ion exchange apparatus for producing high-definition clarity because there is a fear that dust or fine particles in the atmosphere are mixed into the mixing process.
本發明的目的是提供一種適用於製作高清淨度之離子交換裝置的情況且能穩定得到高品質的離子交換樹脂的混合方法及混合裝置。 SUMMARY OF THE INVENTION An object of the present invention is to provide a mixing method and a mixing apparatus which are suitable for producing an ion exchange apparatus of high definition and which can stably obtain a high quality ion exchange resin.
本發明之離子交換樹脂的混合方法，其特徵是：將測量完成之多數種離子交換樹脂與水放入混合槽，藉由一端側及另一端側分別連接至該混合槽的循環管路使上述離子交換樹脂與上述水在幫浦內循環並作攪拌，同時將不活性氣體擴散至該混合槽內。 The method for mixing an ion exchange resin of the present invention is characterized in that a plurality of ion exchange resins and a water which have been measured are placed in a mixing tank, and the above-mentioned one end side and the other end side are respectively connected to a circulation line of the mixing tank to make the above The ion exchange resin is circulated and stirred in the pump with the above water while diffusing the inert gas into the mixing tank.
本發明之離子交換樹脂的混合裝置，是具有：接受測量完成之多數種離子交換樹脂與水的混合槽、一端側及另一端側連接至該混合槽的循環管路、設在該循環管路的幫浦、和將不活性氣體擴散在該混合槽內的氣體擴散手段。 The mixing device of the ion exchange resin of the present invention comprises: a mixing tank for receiving a plurality of ion exchange resins and water, and a circulation line connected to the mixing tank at one end side and the other end side, and is disposed in the circulation line The pump, and a gas diffusion means for diffusing the inert gas in the mixing tank.
該循環管路上設置管路攪拌器為佳。 It is preferred to provide a line agitator on the circulation line.
該混合槽具有蓋且設置氣體排出手段為佳。 It is preferable that the mixing tank has a lid and a gas discharge means is provided.
最好使用氮氣作為不活性氣體。 It is preferable to use nitrogen as an inert gas.
本發明中，從混合槽將混合完成之離子交換樹脂排出移送時，也藉由上述循環管路使離子交換樹脂與水作循環。 In the present invention, when the mixed ion exchange resin is discharged and transferred from the mixing tank, the ion exchange resin and the water are also circulated by the circulation line.
本發明之離子交換樹脂的混合方法及裝置中，藉由循環管路之幫浦，從混合槽內的下部抽取水的同時也抽取離子交換樹脂，並經由循環管路回到混合槽的上部。藉由反覆此動作，混合槽內的多數種離子交換樹脂產生流動，而在混合槽內作攪拌‧混合。再者，本發明中藉著使不活性氣體擴散(起泡)至混合槽內的水中，更給予複雜的流動，提高攪拌效率，因而可在短時間內得到平均的離子交換樹脂的混合狀態。 In the method and apparatus for mixing an ion exchange resin of the present invention, the ion exchange resin is also withdrawn from the lower portion of the mixing tank by the pump of the circulation line, and is returned to the upper portion of the mixing tank via the circulation line. By repeating this action, a large amount of the ion exchange resin in the mixing tank is caused to flow, and the mixture is stirred and mixed in the mixing tank. Further, in the present invention, by diffusing (foaming) the inert gas into the water in the mixing tank, more complicated flow is imparted, and the stirring efficiency is improved, so that the mixed state of the average ion exchange resin can be obtained in a short time.
本發明中，將混合槽作成有蓋且附加氣體排出手段的半密閉狀態，在該混合槽內藉著擴散不活性氣體，在混合槽內造成一定的壓力，且平時不活性氣體從混合槽內透過氣體排出手段被放出外部，因而可以防止包含在大氣中的塵埃或微粒子的混入。 In the present invention, the mixing tank is formed into a semi-sealed state with a lid and a gas discharge means, and a certain pressure is generated in the mixing tank by diffusing the inert gas in the mixing tank, and the inert gas is normally permeated from the mixing tank. Since the gas discharge means is discharged to the outside, it is possible to prevent the incorporation of dust or fine particles contained in the atmosphere.
藉著在循環管路上設置管路攪拌器，提升離子交換樹脂的混合效率。 The mixing efficiency of the ion exchange resin is enhanced by providing a line agitator on the circulation line.
從易取得度或清淨度及成本面考量最好使用高純度的氮氣作為不活性氣體。 It is preferable to use high-purity nitrogen as an inert gas from the viewpoint of easy availability or cleanliness and cost.
作為使用在循環管路的幫浦，以使用樹脂製 的空氣幫浦為佳。藉由使用樹脂製的空氣幫浦，可以抑制不純物從幫浦溶出之外，也可以輸送氣體混入液。又，因為是以壓縮空氣作驅動所以也不會因超載導致發熱。再者，空氣調節器的調節上可以輕易控制吐出壓力，非常安全。 As a pump used in the circulation line, it is made of resin. The air pump is better. By using an air pump made of a resin, it is possible to suppress the elution of impurities from the pump, and it is also possible to transport a gas mixture. Moreover, since it is driven by compressed air, it does not cause heat due to overload. Moreover, the adjustment of the air conditioner can easily control the discharge pressure, which is very safe.

[第1圖]本發明的說明圖。 [Fig. 1] An explanatory view of the present invention.
以下，更詳細說明本發明。第1圖是關於本發明之實施形態的離子交換樹脂的混合裝置系統圖。 Hereinafter, the present invention will be described in more detail. Fig. 1 is a system diagram of a mixing device for an ion exchange resin according to an embodiment of the present invention.
混合槽1具有頂蓋1a，該頂蓋1a上設有氣體流出口2作為氣體排出手段。該氣體流出口2上也可以設置過濾器、或僅容許氣體從混合槽1內流出的止回閥。 The mixing tank 1 has a top cover 1a on which a gas outflow port 2 is provided as a gas discharge means. A filter or a check valve that allows only gas to flow out of the mixing tank 1 may be provided in the gas outflow port 2.
在混合槽1內的下部設有通氣管3，作為不活性氣體的氮氣可以從氮氣汽缸等氣體源介由氣體配管4及閥5作供給。在混合槽1內之上部，設置有阻止離子交換樹脂的通過，卻容許水通過的濾網6，而配管7連接至該濾網6。 A vent pipe 3 is provided in a lower portion of the mixing tank 1, and nitrogen gas as an inert gas can be supplied from a gas source such as a nitrogen cylinder through the gas pipe 4 and the valve 5. In the upper portion of the mixing tank 1, a screen 6 that blocks the passage of the ion exchange resin but allows water to pass therethrough is provided, and the pipe 7 is connected to the screen 6.
循環管路10的流入端連接至混合槽1的底部，該循環管路10的流出端連接至混合槽1的上部。在該循環管路10設有空氣幫浦11與管路攪拌器12。較空氣幫浦11靠近流入端側的循環管路10分歧出移送配管 13，且藉由設在該移送配管13之空氣幫浦14可將混合完成之離子交換樹脂移送到填充裝置(略圖示)。 The inflow end of the circulation line 10 is connected to the bottom of the mixing tank 1, and the outflow end of the circulation line 10 is connected to the upper portion of the mixing tank 1. An air pump 11 and a line agitator 12 are provided in the circulation line 10. The transfer pipe 10 is branched from the circulation line 10 near the inflow end side of the air pump 11 13. The mixed ion exchange resin can be transferred to the filling device (not shown) by the air pump 14 provided in the transfer pipe 13.
作為該混合完成之離子交換樹脂的移送配管，可以在管路攪拌器之出口配管上設置分歧出的配管並朝填充裝置移送。此時，僅需1台空氣幫浦即可完成。 As the transfer piping of the ion exchange resin in which the mixing is completed, the branch pipes which are branched can be provided in the outlet pipe of the line agitator and transferred to the filling device. At this point, only one air pump is needed.
以貫穿混合槽1之頂蓋1a的方式，設置陰離子交換樹脂的導入配管16和陽離子交換樹脂的導入配管17、和水的導入配管18。 The introduction pipe 16 of the anion exchange resin, the introduction pipe 17 of the cation exchange resin, and the introduction pipe 18 for water are provided so as to penetrate the top cover 1a of the mixing tank 1.
本發明中所謂被混合之多數種離子交換樹脂，如陽離子交換樹脂與陰離子交換樹脂般離子基具有陽離子交換性或者具有陰離子交換性的差異之外，即使相同陽離子交換樹脂也有強酸性型陽離子交換樹脂與弱酸性型陽離子交換樹脂的情況，即使相同陰離子交換樹脂中也有強鹼性型陰離子交換樹脂與弱鹼性型陰離子交換樹脂的組合般，離子基之解離性不同的離子交換樹脂彼此之間的情況。 In the present invention, a plurality of ion exchange resins to be mixed, such as a cation exchange resin and an anion exchange resin, have a cation exchange property or an anion exchange property, and even a strong acid type cation exchange resin is used even in the same cation exchange resin. In the case of a weakly acidic cation exchange resin, even if the same anion exchange resin has a combination of a strong basic anion exchange resin and a weakly basic anion exchange resin, the ion exchange resins having different ion groups have different dissociation properties. Happening.
藉由上述構造之混合裝置的離子交換樹脂的混合順序如以下所述。 The mixing order of the ion exchange resin by the mixing device of the above configuration is as follows.
i)使氮氣從空的混合槽1內由通氣管3流出，再使混合槽1內的空氣從氣體流出口2流出，使得混合槽1內形成清靜的氮氣氛圍。 i) Nitrogen gas is allowed to flow out of the vent pipe 3 from the empty mixing tank 1, and the air in the mixing tank 1 is allowed to flow out from the gas outflow port 2, so that a quiet nitrogen atmosphere is formed in the mixing tank 1.
ii)將所測量之陰離子交換樹脂與陽離子交換樹脂與水一起藉由配管16、17導入至混合槽1內。 Ii) The measured anion exchange resin and the cation exchange resin are introduced into the mixing tank 1 through the pipes 16, 17 together with water.
iii)從濾網6到水溢出為止藉由配管18將水導入混合槽1內。使用於離子交換樹脂之混合的水為超純水層級的水，所以用電極式液位計無法測定水位。因此，在本實施形態中，藉著利用濾網6的溢出形式來決定水位。 Iii) Water is introduced into the mixing tank 1 through the pipe 18 from the screen 6 to the overflow of water. The water used for the mixing of the ion exchange resin is water of an ultrapure water level, so the water level cannot be measured by an electrode type liquid level gauge. Therefore, in the present embodiment, the water level is determined by utilizing the overflow form of the screen 6.
iv)使空氣幫浦11運作，讓離子交換樹脂及水的混合漿料通過循環管路10，並在混合槽1內產生流動以混合並攪拌離子交換樹脂。 Iv) The air pump 11 is operated, a mixed slurry of ion exchange resin and water is passed through the circulation line 10, and a flow is generated in the mixing tank 1 to mix and stir the ion exchange resin.
v)進行預定時間的上述iv)混合之後，停止空氣幫浦11，再使空氣幫浦14運作以將混合完成之離子交換樹脂朝填充裝置移送。在該移送步驟中為了不讓外部空氣混入混合槽1內而以使氮氣從氣體流出口2排出的方式，持續朝通氣管3供給氮氣。再者，離子交換樹脂的分離容易發生的情況下，也可在將離子交換樹脂朝填充裝置移送時使空氣幫浦11運作以持續混合離子交換樹脂。 v) After the iv) mixing for the predetermined time, the air pump 11 is stopped, and the air pump 14 is operated to transfer the mixed ion exchange resin toward the filling device. In the transfer step, in order to prevent the outside air from being mixed into the mixing tank 1, the nitrogen gas is continuously supplied to the vent pipe 3 so that the nitrogen gas is discharged from the gas outflow port 2. Further, in the case where separation of the ion exchange resin is likely to occur, the air pump 11 can be operated to continuously mix the ion exchange resin while the ion exchange resin is being transferred to the filling device.
根據相關離子交換樹脂的混合方法及混合裝置，可以防止在離子交換樹脂的混合步驟中空氣中的塵埃或微粒子混入混合槽1內。因而，高清淨度的混合離子交換樹脂被填充至離子交換樹脂塔。藉此，可以製造出水質良好之超純水等的離子交換水。本發明適用於超純水製造裝置之中，特別是子系統(二次純水系統)的離子交換研磨機(非再生型離子交換裝置)的製作(離子交換樹脂的充填)。本發明特別適用於用來製作高純度之超純水的超 純水製造裝置，例如使用於晶圓製造、半導體製造等的超純水製造裝置的離子交換裝置的製作(離子交換樹脂的填充)。依據具有已填充藉由本發明所混合之離子交換樹脂的離子交換裝置的超純水製造裝置，可以輕易製造出金屬濃度在1ppt以下甚至0.1ppt以下的超純水。 According to the mixing method and the mixing device of the related ion exchange resin, it is possible to prevent dust or fine particles in the air from being mixed into the mixing tank 1 in the mixing step of the ion exchange resin. Thus, a high-definition, mixed ion exchange resin is filled into the ion exchange resin column. Thereby, ion-exchanged water, such as ultrapure water of a good water quality, can be manufactured. The present invention is suitable for use in an ultrapure water production apparatus, particularly an ion exchange mill (non-regeneration type ion exchange apparatus) of a subsystem (secondary pure water system) (filling of an ion exchange resin). The invention is particularly suitable for the production of ultra-pure water of high purity The pure water producing apparatus is used, for example, in the production of an ion exchange apparatus (filling of an ion exchange resin) for an ultrapure water production apparatus such as wafer manufacturing or semiconductor manufacturing. According to the ultrapure water production apparatus having the ion exchange apparatus filled with the ion exchange resin mixed by the present invention, ultrapure water having a metal concentration of 1 ppt or less and even 0.1 ppt or less can be easily produced.
以下說明實施例及比較例。 The examples and comparative examples will be described below.
使用第1圖所表示之混合裝置按照上述順序，將陰離子交換樹脂與陽離子交換樹脂以容積比1：1作混合之後，在無塵室內填充至離子交換樹脂的容器(72L)並製作離子交換裝置。將該離子交換裝置中如表1所表示的金屬離子濃度之超純水以SV=60/h作24小時通水。在第24小時所採取的離子交換裝置流出水的水質如表1所表示。 The anion exchange resin and the cation exchange resin were mixed at a volume ratio of 1:1 in the above-described order using the mixing apparatus shown in Fig. 1, and then filled in a container (72L) of the ion exchange resin in a clean room to prepare an ion exchange apparatus. . The ultrapure water having the metal ion concentration shown in Table 1 in the ion exchange apparatus was passed through water at SV = 60 / h for 24 hours. The water quality of the effluent from the ion exchange unit taken at the 24th hour is shown in Table 1.
離子交換樹脂的混合步驟中，除了不進行氮氣的擴散外，其餘與實施例1相同地製作離子交換裝置，並作通水試驗。在第24小時所採取的離子交換裝置流出水的水質如表1所示。 In the mixing step of the ion exchange resin, an ion exchange apparatus was prepared in the same manner as in Example 1 except that the diffusion of nitrogen gas was not carried out, and the water passing test was performed. The water quality of the effluent from the ion exchange unit taken at the 24th hour is shown in Table 1.
從表1可以清楚了解，藉著利用本發明之離子交換樹脂的混合方法及混合裝置可以得到高水質的超純水。 As is clear from Table 1, high-quality ultrapure water can be obtained by using the mixing method and mixing device of the ion exchange resin of the present invention.
以上利用特定形態說明本發明，但只要不脫離本發明的主旨及範圍，可以有各種變化，這是本業者所明瞭。 The present invention has been described above by way of specific examples, and various modifications may be made without departing from the spirit and scope of the invention.
