Description

The utility model relates to filtering plants and can be used for water purification in agriculture and public utilities, at power plants at storage ponds, for the treatment of mine and quarry waters.

It is known a filtering device comprising a reservoir, which is made partially open with hydraulically connected to each other, closed by a receiving chamber, a metaten camera, a clarification chamber, a biofilter chamber with at least two sections hydraulically interconnected. Between the sections, a dividing longitudinal partition is installed with a drain shelf made in its upper part. The biofilter chamber is equipped with a neck connected to the atmosphere. The biofilter is located in both sections of the camera. One of the sections of the biofilter is made inlet and hydraulically communicated with the metaten chamber. Another section of the biofilter is made output and hydraulically connected with the clarification chamber. (RF patent No. 2299863, μL C02F 3/00, C02F 9/14, publ. 27.05.2007).

The disadvantages of this device are structural complexity and limited performance due to the size of the tank.

Closest to the proposed one is the Kudryavtsev multisection filtering device, containing adjoining one to another sections with inlet and outlet cavities made in each section and located in the sorbent sections. The sections have the same dimensions and are each made in the form of a prism with a hexagonal base and pairwise identical and parallel the walls. The base of the sections form two end walls of the installation parallel to each other, the sections adjoin one another so that the side wall separating two adjacent sections is common to them, and all the walls are rigidly interconnected. (RF patent No. 2304014, Ml. B01D 24/12, B01D 25/02, C02F 1/42, published on 08/10/2007.

The disadvantages of this device are the structural complexity of the sections, the increased requirements for the shape of the sections due to the need for their tight adjacency to each other to eliminate fluid leaks between the sections and the complexity of the regeneration of the sorbent.

The technical problem to which the proposal is directed is the creation of a structurally simple, economical and technological filtering device.

The technical result of the proposal is to create an easy-to-maintain, reliable and durable device, while constantly maintaining the specified quality of liquid filtration.

To solve this technical problem, a multi-section filtering device is proposed, containing sections connected to one another, filled with filtering sorption material, in each section supply and discharge cavities are made, sections are made in the form of hollow columns with a blind bottom, the supply cavities are made at the base of the columns and closed with a fine mesh mesh, outlet cavities are made in the upper part of the columns, inlet and outlet cavities of each column are made from its opposite sides, the columns are mounted vert Optically, the adjacency of adjacent columns with the sides is sealed. Leading cavities can be made with sealing gates.

The essence of the utility model is illustrated by the drawings of a non-exclusive example of a multi-section filtering device. In FIG. 1 shows a general view of one hollow column made of cylindrical rings, FIGS. 2, 3, 4 are a front, side and top view, respectively, in FIG. 5 is a general view of a multi-section filtering device; FIG. 6 is a front view; FIG. 7 is a top view.

The figures indicate: inlet cavity 1 (a fine mesh screen covering the inlet cavity 1, not shown), outlet cavity 2, material 3, sealing the adjacency of adjacent columns. Fine mesh and sealing gates on the inlet cavities 1 are not shown.

The column material is reinforced concrete or reinforced plastic pipes. In particular, concrete rings of the standard size used for the manufacture of wells can be used.

The columns are filled with various filtering sorption material (bentonite, zeolite, coal, bauxite, aluminum oxide or other other sorption material - not shown).

The device operates as follows:

Through the inlet cavities 1, dirty water enters the columns, passes through a layer of sorption material and already purified by gravity exits through the outlet cavity 2 in the upper part of the column, the lower edge of the outlet cavity 2 should not be higher than the level of purified pond water. Pumping of purified water from the pond to organize the effect of running water, in order to avoid siltation and stagnation, is carried out by a pumping station (not shown) at the outlet of the pond.

Supports for moving pumping equipment can be mounted on top of columns with the possibility of lowering them into the column to pump dirty loading material to the surface. On the surface, the dirty load is separated from the water, after which new loading material is poured into the columns.

If the supply cavities are made with sealing gates, then before cleaning each column and replacing the sorption material in it with a shutter, the column is turned off.

The applicant manufactured and successfully tested prototypes of the proposed multi-section filtering device. Depending on the required productivity, vertical columns were made with a diameter of 0.5 m to 3 meters, height depending on the depth of the pond from 0.5 m to 10 m, the size of the supply cavities from 0.3 m to 9 m high, from 0.4 m to 2.8 m wide, The size of the discharge cavities 2 is from 0.3 m to 2.8 m wide, the lower edge of which should not be higher than the level of purified water in the pond.

Although the present proposal has been demonstrated and described with reference to its preferred embodiment, it will be understood by those skilled in the art that various other changes may be made to it regarding materials, shapes and details, without departing from the essence and scope of this technical solution defined the following formula.

This technical solution avoids the need for the construction of dams and other hydraulic structures.
