Description

Technical field

The proposed utility model in the form of a combifilter for water purification is designed to remove various contaminants from water, including suspended solids.

State of the art

There are various filters for water purification, in which the processes of water purification from various contaminants, including suspended solids, are carried out.

Known filters for water purification include a housing with inlet and outlet nozzles located on the outside and placed inside the filter load with the output of purified water through the drainage system (Frog B.N., Levchenko A.P. Water treatment. M .: MGU, 1996. - pp. 229-304.)

A significant disadvantage of the proposed device is the low degree of water purification from suspended solids.

The closest technical solution to the proposed utility model is a technical solution in the form of a combifilter for water purification from suspended solids (RF patent No. 2060788, Combined filter for water purification, reg. 1993.05.27, publ. 1996.05. authors: Mirkis I.M., Mirkis V.I., Arkhipov A.I.).

The essence of the known invention (prototype) is that the combifilter for water purification includes a housing, on the outside of which there are inlet and outlet pipes, and inside the housing is divided into consecutive sections.

A significant disadvantage of combifilters is the low degree of water purification from suspended solids by filtration due to the lack of a mixing chamber of reagents with purified water.

Utility Model Disclosure

The objective of the utility model is to develop a new combifilter design that provides a high degree of water purification from suspended solids.

The technical result is to increase the efficiency of water purification from suspended solids.

The set task and the specified technical result are achieved by the fact that the combifilter for water purification from suspended solids includes a housing, on the outside of which there are inlet and outlet pipes, and inside successively arranged layers separated by a partition with filtering and drainage loads, and a distinctive feature is that before the filtering load, a mixing chamber with a floating nozzle with particle sizes from 1.0 to 50.0 mm is additionally placed, and the ratio of the particle sizes of the filtering and drainage loads is from 1:2 to 1:10, respectively.

Implementation of the utility model

The proposed combifilter for water purification from suspended solids includes a housing 1, on the outer side of which there are pipes 4 and 11 for the output of wash water, a pipe 7 for supplying dirty water, a pipe 8 for supplying a reagent solution, a pipe 16 for discharging purified water and a pipe 18 for supplying wash water, and inside the housing there is a filtering load 2, located between grates 3 and 12, above which a mixing chamber 6 with nozzles 5 and 10 is installed, inside which is a cylindrical cup 17 with a floating nozzle 9 with particle sizes from 1 mm to 50 mm, and below the filter loading layer of drainage loading 13 is located, and the ratio of particle sizes of the filtering and drainage loadings is respectively from 1:2 to 1:10, which was proved experimentally. At the same time, a drainage system is located inside the drainage load in the form of a perforated pipe 14 with holes 15.

The principle of operation of the proposed combifilter is as follows. The source (dirty) water through the inlet pipe 7, as well as the reagent solution through the pipe 8, enter the combifilter body 1, directly into the cylindrical cup 17 with a floating nozzle 9 with particle sizes from 1.0 mm to 50.0 mm. Due to the intensive movement of particles 9, the reagent solution is effectively mixed with water, which increases the effect of water purification. The particle size of the floating packing was substantiated experimentally. Further, the water treated with the reagent is supplied through the grate 3 to the layer of the filtering load 2 and then is discharged through the drainage layer 13 and the drainage system 14 and further through the outlet pipe 16. In this case, the ratio of particle sizes of the filtering and drainage loads is from 1:2 to 1:10, respectively. which has been proven experimentally.

Flushing of the filter consists in the supply of wash water through pipe 18 and with the withdrawal of waste wash water through pipes 4 and 11.

When using the proposed combifilter for water purification, the quality of purified water in terms of suspended solids does not exceed 0.5 mg/l. In the case of using known devices, the concentration of suspended solids is about 1.5 mg/l, which in some cases does not guarantee the quality of drinking water.

The proposed combifilter for water purification can be autonomously used for purification of both natural waters, as well as wastewater from various industries as a local treatment plant with an area smaller than in the case of using analogue structures up to 1.5-2.0 times.
