Detailed description of the invention
Below in conjunction with embodiment, the technical solution of the utility model is described in detail.
As it is shown in figure 1, this utility model embodiment a kind of for prepare H-acid isolation and
Defecator, it is characterised in that described isolation and defecator include acid preparing device 1, dilute
Sulphuric acid surge tank 2, separation kettle 3, cooling reactor 5 and filter 6；The outlet of acid preparing device 1
Import with dilute sulfuric acid surge tank 2 is connected, the outlet of dilute sulfuric acid surge tank 2 and separation kettle 3
First import connects, and separation kettle 3 is provided with alkali fusion thing import, the material outlet of separation kettle 3 with
The import of cooling reactor 5 connects, and the outlet of cooling reactor 5 and the entrance of filter 6 connect, and filter
The H-acid filtered solid outlet that device 6 is provided with.
In above-described embodiment, isolation and defecator to dilution after alkali fusion thing, carry out isolation and
