Description

The invention relates to desalination devices for salt or sea water by reverse osmosis.

Known reverse osmosis desalination plant, which consists of a high-pressure plunger pump, pre-filter, desalination module, while the pre-filter is installed between the discharge pipe of the high-pressure plunger pump and the inlet of the desalination module, and the filter cartridges are made of different diameters and pores, moreover in the cavity of each cartridge of large diameter and with larger pores at least three cartridges of a smaller diameter are placed tra and with smaller pores and, moreover, the filter cartridges are capable of elastic deformation in the radial direction under the action of a pulsed pressure seawater (Pat. Russian №2186709, IPC B63J 1/00, publ. 10.08.2002 g).

This installation is selected as a prototype of the proposed technical solution.

The disadvantages of the prototype:

- increased vibration and hydrodynamic noise created by a working high-pressure plunger pump;

- a pre-filter installed between the discharge pipe of the high pressure plunger pump and the inlet pipe of the desalination module;

- the energy of the pressure pulse is expended on the work of the elastic deformation of the cartridges and is extinguished;

- vibration and hydrodynamic noise of a working high-pressure plunger pump — the natural state of the working mechanism, vibration and hydrodynamic noise are caused by reciprocating movements (the number of double strokes) of the plunger and the operation of the power device driving the plunger, the number of double strokes made by the plunger is 85, 100 or more per minute, this creates vibration and hydrodynamic noise, a pre-filter installed between the discharge pipe of the high-pressure plunger pump and odnym pipe desalination module can not affect this state;

- the pre-filter installed after the high-pressure plunger pump on the discharge pipe does not protect the working cavity of the hydraulic cylinder of the high-pressure plunger pump from the ingress of sand, solid objects, etc., which can cause rapid wear of the working cavity of the hydraulic cylinder and plunger when sand enters it will work as an abrasive, forming on the working surfaces of the hydraulic cylinder and plunger a development and a groove, which will lead to the flow of water, and the high-pressure plunger pump will fail, if not to give the desired pressure, larger objects will cause jamming;

- when the high-pressure plunger pump is running, water is supplied to the pre-filter under pulse pressure (surges), the value of which can vary from the suction cycle to the discharge cycle, the pressure pulse can be 2 ÷ 100 kg / cm2, while the pressure pulse energy is spent on the work of the elastic deformation of the cartridges is thus extinguished, as a result, water does not come from the cartridge pre-filter to the desalination module not in pulses, but under a certain constant working pressure of 50 ÷ 6 0 kg / cm2, therefore, in this reverse osmosis desalination plant, the desalination module that needs a higher working pressure cannot work, the desalination module will not work after installing the pre-filter, if it is designed for a higher pressure, a desalination module with filters with larger pores, designed for such pressure, and this will degrade the quality of desalinated water.

These shortcomings create problems when using reverse osmosis systems on ships and submarines.

The task of the invention is the elimination of these disadvantages:

- reduce hydrodynamic noise and vibration from a working high-pressure pump;

- installing pre-filters on the suction line connected to the left working cavity and installing pre-filters on the suction line attached to the right working cavity of a smaller diameter cylinder;

- all the pressure energy of the high pressure pump is spent on desalination;

- an installation option for single pre-filters and a disco-tubular filter apparatus with manual cleaning of pre-filters and a disco-tubular filter apparatus is provided;

- an option is provided for installing parallel pre-filters and disc-tube apparatus filters with manual cleaning of pre-filters and disc-tube apparatus filters;

- an option is provided for washing individual pre-filters and a disco-tubular filter apparatus;

- an option is provided for washing pre-filters and disco-tubular filter apparatuses installed in parallel;

- pressure regulation in the discharge line is provided;

- provides for the regulation of the amount of salt or sea water supplied to the disco-tubular filter apparatus for desalination;

- use of desalination plant as a high pressure pump;

- the use of a desalination plant as a high pressure metering pump;

- manufacture of a smaller hydraulic cylinder, rod, plunger-piston, check valves, pipes, pipes, taps from corrosion-resistant steel.
