Description

A group of utility models relates to the field of purification of liquids by ion exchange and can be used for all types of H, Na cation exchange filters and sand filters of chemical water treatment systems at thermal stations and industrial enterprises.

A lower distribution device for water treatment filters is known, comprising a horizontal manifold attached to it along the side generatrix distribution pipes and connected to the pipes along the bottom forming drain caps by means of bushings. Drain cap bushings are made in lengths that increase from the periphery to the center of the filter (see ed. Certificate No. 1214150, class B01D 24/42, 1986).

The disadvantage of this device is the use of bushings with drainage caps for installation on distribution pipes, which leads to a decrease in the durability of the device, the need for frequent change of caps. In addition, such a mounting scheme of the caps does not ensure uniform distribution of the fluid flow, leading to increased metal consumption. Increased vibrations are possible, especially during flushing, which lead to increased wear of the filter elements.

Known drainage distribution system of the collector beam type, consisting of drainage caps and distribution pipes installed over the entire area of the filter, in which drainage caps for installation in the holes of the distribution pipes are made of polypropylene and consist of a filter head with slotted nozzles and an axial spline coupling in the form of six petals (see RF patent No. 32409, IPC 7 B01D 24/00, 2003)

The disadvantage of this device is the high cost of maintenance, since when the upper part of the cap is destroyed, the cap changes together with the locking sleeve. In addition, when replacing the caps, the petals of the spline coupling may come off and their remnants fall into the drainage system, clogging it.

Known drainage distribution device of an ion exchange filter containing a collector having the ability to mount on

filter outlet, radiation tubes fixed to the collector, supporting tubes with filter elements (see RF patent No. 17281, IPC 7 В01D 24/38, 2001)

The disadvantage of this device is the use of metal for the manufacture of radiation tubes and pipes. Such a cap fastening scheme is short-lived, has low corrosion resistance and low resistance to aggressive environments.

The closest is a drainage distribution device of an ion-exchange filter, containing an outlet pipe with collectors fixed to it, equipped with radiation distribution pipes, and cap filter elements removably connected to the distribution pipes by means of pipes (see RF patent No. 2137526, IPC 6 B01D 24/38 , 1999). This decision was made as a prototype.

The disadvantage of this device is the use of metal for the manufacture of radiation tubes and pipes, which leads to increased metal consumption and high cost of the device. Such a cap fastening scheme is short-lived, has low corrosion resistance and low resistance to aggressive environments.

Known drainage distribution device for bulk filters containing a perforated pipe with a perforated element placed above it, made in the form of cylindrical cassettes, the side surface of which consists of longitudinal teeth of the T-section, the ends of which in the section are rectangular (see A.S. USSR No. 486758, IPC B01D 23/24, 1976).

The disadvantage of this solution is the complexity of the design, low maintainability, which leads to an increase in the cost of construction.

A known solution of the drainage distribution device of the filter, containing perforated pipes and located on them connected to one another by slotted elements made in the form of cylinders. At one end of the cylinders, a tide is made in the form of a ring on the inner cylindrical surface, and at the other end is a tide in the form of a ring on the outer cylindrical surface. The slots are calibrated according to the generatrix of the cylinder between the tides (see AS of the USSR No. 1456183, IPC 4 B01D 23/20, 1989).

A disadvantage of the known solution is the complexity of the design, leading to higher construction costs. In addition, the disadvantage is the inefficiency of using closely mounted perforated elements, which leads to a rise in the cost of construction.

The closest is the solution of beam distribution pipes with cap filter elements detachably connected to the distribution pipes by means of nozzles (see RF patent No. 2137526, IPC 6 B01D 24/38, 1999). This decision was made as a prototype.

The disadvantage of this device is the use of metal for the manufacture of radiation tubes and pipes, which leads to increased metal consumption and high cost of the device.

The problem solved by the utility model is to increase the service life of the drainage distribution device, and repeatedly reduce the cost of the device.

The problem is solved due to the fact that in the known drainage distribution device of an ion-exchange filter containing an outlet pipe with collectors fixed to it provided with beam distribution pipes, and cap filter elements removably connected to the distribution pipes by means of pipes, in accordance with the utility model, distribution pipes and nozzles attached to them are made of plastic

The problem is also solved due to the fact that in the known beam distribution pipe with nozzles in accordance with a utility model, the distribution pipe with nozzles is made of plastic.

The nozzles are made in the form of fittings connected to the pipe one-piece.

The nozzles are made in the form of flap spacers, detachably connected to the distribution pipe.

The nozzles are made of polyvinyl chloride (PVC) or polypropylene.

The distribution pipe is made of polyvinyl chloride (PVC), or polypropylene, or low pressure polyethylene (HDPE).

The technical result from the use of the utility model is that due to the implementation of the drainage distribution device of the ion-exchange filter, comprising an outlet pipe with collectors fixed to it, provided with beam distribution pipes, and cap filter elements removably connected to

distribution pipes by means of nozzles, in which the distribution pipes and the nozzles attached to them are made of plastic, can reduce the metal consumption, increase the service life of the drainage distribution device, reduce the cost of the device.

The technical result from the use of the utility model is that the implementation of the distribution pipe with pipes made of plastic, and the pipes can be both removable and connected to the pipe inseparably, provides improved maintainability, increased device life and reduced metal consumption, manufacturing and maintenance costs .

6 is an example of the use of a plastic filter element.

The drainage distribution device 1 comprises an outlet pipe 2 to which collectors 3 are attached. To each collector 3 there are attached beam distribution pipes 4 with pipes 5. The beam distribution pipes 4 can be permanently attached to the collectors, or can be removable. Beam distribution pipes 4 and nozzles 5 can be made of plastic, for example, PVC or polypropylene.

Each nozzle 5 is equipped with a threaded end 6, onto which a removable cap filter element 7 is subsequently screwed. The filter elements 7 can be applied in any shape and made of any kind of material (see Figs. 3, 4, 5, 6).

The nozzles 5 can be made in the form of fittings and welded to the beam tubes 4 by heat or cold welding (see figure 5). Pipes 5 can also be used in the form of flap spacers (see Fig. 4), which provide reliable and tight fastening of the pipe to the radial tube 4.

The collectors 3 and the beam distribution pipes 4 can be located relative to each other and relative to the bottom of the filter by any desired method.

The proposed drainage distribution device operates as follows. The processed liquid passes through a layer of ion-exchange resin 8, where it is purified from the dissolved chemical compounds. Next, the liquid filtered from the grains of the ion-exchange resin and mechanical impurities in the filtering elements 7 enters through the nozzles 5 and the beam distribution pipes 4 into the collectors 3. Then the liquid enters the outlet 2 and is removed from the filter.

Washing of the ion-exchange resin or other filling charge is carried out in the reverse order.

A drainage distribution device with beam distribution pipes and nozzles made of plastic is less susceptible to the influence of an aggressive environment, therefore it is more durable.

Drainage distribution device and beam distribution couplings with nozzles can be manufactured using known technological equipment.
