INSTALLATION FOR EXTRACTION OF COLORANTS AND HEAVY METALS FROM A TECHNOLOGICAL SOLUTION Russian patent published in 2003 - IPC

FIELD: extraction of colorants and heavy metals from technological solutions. SUBSTANCE: the invention is dealt with colorants and heavy metals extraction from a technological solution. It relates to treatment of industrial sewage, in particular, to the dyeing-finishing engineering, and may be used for extraction of the coloring agents and-or heavy metals from technological solutions. The Installation has a body made in the form of a furring, which is divided by partitions for a loading, a working and a downpour sections, at that the loading section has bunkers with the metering units, that are linked with the drainage branch-pipes in the partition, and in the working section on its lower partition there is a container supplied with the rabble and at that in the side part of the container there is an opening, which is linked with the inlet branch-pipe of the furring, and its bottom has the drainage branch-pipes with valves; the downpour section is supplied with filtration columns with distributing lattices and a filtering material; and the filtration columns are located under the drainage branch-pipes of the container and fixed on the a shaft of the furring with a possibility to rotate around it, and under them there are the ring-type collectors, outlets of which are linked with the outlet branch-pipes in the bottom of the furring. EFFECT: availability of an installation for extraction of the coloring agents and-or heavy metals from the technological solutions. 1 dwg
