Description

The invention relates to the purification of liquids, namely to structures for the mechanical treatment of wastewater by the method of gravitational sedimentation, and can be used in the systems of circulating water supply of industrial enterprises.

The aim of the invention is to expand the technological capabilities of the device.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The device consists of a housing 1 with input nodes 2 and distribution 3 of the source liquid, a thin layer module 4 in the form of plates 5 installed parallel to the sides of the housing and at an angle to its vertical axis plates 5, the height of which increases from the center to the periphery. Plate 5 is installed symmetrically to each other with the formation of the gap 6, located along the longitudinal axis of the housing. The device also contains a compressed air collector 7 located in the lower part of the gap 6, a clarified liquid outlet unit 8, a heavy contaminant outlet unit 9 and a floating impurity unit made in the form of a tray 10 placed in the upper part of the body and provided with a branch pipe 11.

The housing in the lower part ends with a conical bottom 12 for collecting heavy contaminants.

The device works as follows.

The contaminated liquid enters the housing 1 through the node 2, passes the distribution node 3, and moves between the precipitation plates 5, where it is removed

the knowledge. Due to the inclination of the plates 5, the released contaminants move, depending on their density, down (heavy soils) or up (floating soils) to the central gap 6 (corridor), where air bubbles coming from the collector 7 are picked up and further discharged through tray 10 and pipe 11 of the device. Heavy contaminants are collected at the bottom 12 and discharged through the node 9. The clarified liquid is withdrawn in a known manner through the node 8.

The proposed device allows cleaning of the fluid in the complex from both scavenger substances and floating substances, for example, oil products in a thin layer settling mode, and also ensures reliable evacuation of released contaminants.
