본 고안은 플루오르화수소(HF)의 수용액제조장치에 관한 것이다.The present invention relates to an apparatus for producing an aqueous solution of hydrogen fluoride (HF).

유리의 에칭, 주물의 스케일제거, 혹은 인공수정의 원료등의 용도로 사용되고 있는 플로우로화수소수용액은, 통상 플루오르화수소를 정제수(탈이온수)등에 소정비율로 희석하여 제조된다. 종래에는, 실사용자가 플루오로화수소수용액을 사용하고자 할때, 일정용기에 들어있는 플루오르화수소를 구입하고 이를 혼합탱크에 소정량 투입한 후 희석비율에 따라 탈이온수를 비이커나 전자저울등으로 적당량 측정하여 희석하는 수작업방식을 사용하거나, 혹은, 플루오로화수소의 제조업자가 미리 혼합하여 공급하는 것을 이용하기도 한다. 플루오로화수소의 제조업자는 대형혼합 및 저장탱크와 질량유량제어기등 사용하여 대량으로 제조하여 공급한다.A hydrofluoric acid aqueous solution, which is used for etching glass, descaling castings, or raw material for artificial crystals, is usually produced by diluting hydrogen fluoride in purified water (deionized water) at a predetermined ratio. Conventionally, when a real user wants to use a hydrogen fluoride solution, purchase hydrogen fluoride contained in a certain container, put a predetermined amount into a mixing tank, and measure deionized water with a beaker or electronic balance according to the dilution ratio. It is also possible to use a manual method of diluting by dilution or to mix and supply the hydrogen fluoride manufacturer in advance. Manufacturers of hydrogen fluoride are manufactured and supplied in large quantities using large mixing and storage tanks and mass flow controllers.

이와같이, 사용자가 수작업으로 플루오르화수소용액을 제조하는 경우에는, 플루오르화수소와 물을 정확한 비율로 혼합하기가 곤란할 뿐만 아니라, 플루오르화수소 및 그 수용액의 특성자체가 강한 위험성을 가진 것이기 때문에 작업자나 주위물체에 안전사고를 일으킬 위험이 크다. 그리고, 실제 사용할 공장등에서 플루오르화 수소수용액 제조업자가 공급하는 것에 의존할 경우에는, 그 수용액 자체의 가격이 비쌀 뿐만 아니라, 예를들어 10%수용액인 경우 플루오르화수소만을 공급받을 때보다 10배 더 많은 용기를 사용하고 교환하여야 하기 때문에 매우 불편하다.As described above, when the user manually prepares the hydrogen fluoride solution, it is difficult to mix hydrogen fluoride and water in the correct ratio, and the characteristics of hydrogen fluoride and its aqueous solution have a strong risk, so There is a high risk of causing a safety accident. In addition, in case of relying on the supply of the aqueous hydrogen fluoride solution manufacturer in the actual plant, etc., the solution itself is not only expensive, but, for example, 10% aqueous solution, 10 times more containers than only hydrogen fluoride is supplied. It is very inconvenient because it has to be used and exchanged.

따라서, 본 고안의 목적은, 플루오르화수소수용액을 사용하는 현장에서 플루오르화수소와 물을 사용하여 용이하고 정확하게 플루오르화수소수용액을 제조하여 공급할 수 있는 플루오르화수소수용액제조장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide an apparatus for producing a hydrogen fluoride solution, which can easily and accurately manufacture and supply a hydrogen fluoride solution using hydrogen fluoride and water in a field using a hydrogen fluoride solution.
