Process for continuously preparing electronic-grade ammonia water by jet absorption and gradient filtration method

The invention discloses a process for continuously preparing electronic-grade ammonia water by a jet absorption and gradient filtration method, and particularly relates to the technical field of ammonia water production. The method is compact in process, equipment is simple, efficient and easy to control, and the product quality is stable; liquid ammonia with organic matter removed enters the gasifier to be gasified, the needed heat can be greatly reduced, and heat energy can be greatly saved; the method provided by the invention is simple to operate, does not need energy consumption procedures such as multi-stage rectification, and can be continuously and stably operated; according to the method disclosed by the invention, the high-end electronic-grade ammonia water with the metal ion content of less than 10ppt can be prepared; the ammonia gas is efficiently absorbed by water by utilizing a jet absorption method, the retention time is not needed, the capacity release is facilitated, and the energy consumptio
