Abstract
The utility model relates to the technical field of chemical reactors, in particular to a reactor for preparing hydrofluoric acid. The content of metal of the hydrofluoric acid prepared by the reactor is lower and can achieve 1-10ppb, and the quality of the hydrofluoric acid is higher. The reactor comprises a reactor body, and a feed opening and a discharge opening are arranged on the reactor body. The reactor for preparing the hydrofluoric acid is characterized in that a body of the reactor is made of stainless steel or graphite, and an additive inlet is further arranged on the reactor body.
Description
Technical field
The utility model relates to chemical reaction still technical field, is specially the preparation reactor of hydrofluoric acid.
Background technology
The preparation of existing hydrofluoric acid is with a kind of preparation reactor of hydrofluoric acid, it is directly with steel cylinder or full carbon steel, reactor directly heats to descend to produce at water or steam, the metal ion of steel cylinder or full carbon steel will enter in the hydrofluoric acid, cause in the hydrofluoric acid metal ion content higher, reach 1ppm, be only applicable to De Fu Tong in the diode, product is AR level, GR level, EL level.
Summary of the invention
At the problems referred to above, the utility model provides a kind of preparation specific equipment of hydrofluoric acid, and by the hydrofluoric acid of this reactor preparation, its metal content is lower, can reach 1～10ppb, and the hydrofluoric acid quality is higher.
Its technical scheme is such: it comprises the reactor body, and described reactor body is provided with opening for feed and discharge port, it is characterized in that: the kettle of described reactor is stainless steel kettle or graphite kettle.
It is further characterized in that: described reactor body also is provided with the import of additive.
The utility model adopts after the said structure, and kettle adopts stainless steel or graphite, can significantly reduce the content of metal ion in the hydrofluoric acid like this, and the content of metal ion reaches 1ppb～10ppb, and over-all properties is improved; And the setting of the import of additive can in order to handle metal ion, further guarantee the content of lower metal ion in the hydrofluoric acid to increasing additive in the kettle, guarantees the over-all properties of hydrofluoric acid.
