Description

 The invention relates to installations for desalination, softening and desalination of water used in industry and transport.

 A known filter for water purification, comprising a housing with an internal corrosion-resistant coating, a lid and a bottom, to which are connected inlet and outlet pipes with shut-off valves, respectively [1].

 However, this filter is difficult to operate due to the large number of locking elements and the fragility of the corrosion-protective coating.

 A known filter for water purification, comprising a housing made of a corrosion-resistant material with a cover and a bottom, to which are connected inlet and outlet pipes, tie rods for fastening the cover and bottom to the housing, bulk loading, horizontally installed in the housing under the cover and bottom, are permeable only septum drainage water, used to prevent the rash of the load [2].

 The disadvantage of this filter is the difficulty of attaching the cover and the bottom to the filter housing, the complicated system of fixing the drainage partitions in the filter housing, as well as the difficulty of regular reconnection of the flexible pipelines for supplying and discharging water from the filters in the operating and regeneration modes.

 The purpose of the invention is to simplify the operation of filters.

 In FIG. 1 shows a filter, section; in FIG. 2 is another possible embodiment of a filter; in FIG. 3 - pipe with a pipe attached to it; in FIG. 4 - installation for desalination of water.

 The filter contains an upper pipe 1 with an external thread for fastening the supply flexible pipe, an upper elastic ring 2 to prevent leakage and fixation of the upper drainage wall, which consists of a mesh 3 and a perforated disk 4 located on the identical upper elastic ring 5, which performs the same fixing function and prevent leakage and made of a corrosion-resistant material (for example, polyethylene) in the form of a ring with an oblique cut, identical to the upper lower elastic rings 6 and 7 to fix and prevent leakage ki through the lower drainage wall containing the mesh 8 and the perforated disk 9, the lower pipe with an external thread 10 for attaching the outlet flexible pipe, the upper cover 11 and the bottom 12, attached to the housing 13 from a corrosion-resistant material (for example, polyethylene) using flanges 14, welded to the housing 13, additional gaskets 15 of corrosion-resistant rubber. In the case between the drainage partitions placed ion-exchange load 16.

 The filter shown in FIG. 2 differs from that shown in FIG. 1 in that it has an upper pipe 1 for mounting a supply flexible pipe located on the side surface of the housing, the lower pipe 10 is likewise located, and the cover and bottom are fixed to the filter housing using flanges 17.

 In FIG. 4 shows a water desalination plant made using the described filters. The installation contains five filters, the first of which is mechanical, and the rest are cationic and anionic. The filters are interconnected by pipelines, which are fastened to the inlet and outlet pipes of the filters provided with an external thread 18, as shown in FIG. 3.

 In the process, the inlet pipe is connected to the source of the source water, and all other filters are connected in series (or in series-parallel) using flexible pipelines.

 The filter works as follows.

 The source water enters through the pipe 1 and the drainage wall, consisting of a grid 3 and a disk 4, into the ion exchange charge 16, is partially desalted and passes through the pipe 10 to the next filter filled with another load, or to the consumer.

 When the protective effect of the load or the available pressure has been exhausted, the installation is regenerated. In this case, the inlet pipe is disconnected from the inlet pipe 19 and the filter 20 and connected to a source of loosening water, the pipe disconnected from the inlet pipe of the filter 21 is connected to the inlet pipe of a mechanical filter from which the inlet pipe is previously disconnected and the remaining pipes are similarly reconnected, providing current water through each filter from bottom to top. In this case, reconnection is required on the five upper nozzles.

 At the end of the loosening, the pipe 1 is connected to a container with a regeneration solution. Similar actions are carried out with the remaining filters. When washing, filters are connected to a source of wash water.

 Thus, the proposed filter eliminates the use of stop valves, the use of tie rods for attaching covers to the filter housing from corrosion-resistant (polyethylene) material and simplify the system of fixing the drainage partitions in the filter housing.
