Description

 The invention relates to installations for purifying groundwater of water wells from iron and manganese and can be used for water supply of settlements, as well as for local and domestic water supply.

 A known installation for deferrization of underground water of water wells (description of the invention to the patent of the Russian Federation N 2069190, MKI C 02 F 1/64), consisting of a device for aeration, aeration-degassing tank with a plunger and a well head connected to it.

 A disadvantage of the known installation is the need for increased consumption of aerated fluid for injection into the aquifers of the well for a long time, which leads to significant costs during operation of the installation.

 The closest to the claimed invention in terms of features is an installation for purifying water from iron and manganese (description to patent WO 95/19937 MKI 6 C 02 F 1/64, E 03 B 1/04), containing the first pumping system for pumping from a water source water to be purified, a device for aeration of water, a tank for water purification, consisting of an upper chamber, in which there is a device for washing the middle chamber filled with a filter load, and the lower chamber for purified water. The installation is also equipped with a pressure tank and a second pumping system for supplying purified water to the pressure tank and supplying purified water from the pressure tank to the lower chamber of the first tank for the washing process.

 A disadvantage of the known installation is the need to use two pumping systems and two tanks, one of which is pressure head, as well as the use of already purified water for washing, and the unresolved tasks associated with the removal of filtrate with washing water during filter washing.

 These disadvantages reduce the efficiency of the known installation and increase the cost of use.

 In addition, the plant's operating efficiency and operating costs also depend on the amount of dry solids removed from the water source itself.

 The objective of the proposed invention is to increase efficiency and reduce costs by combining in one system all the systems used to clean the underground water of water wells from iron and manganese.

 The problem is solved by the described installation for water purification from iron and manganese, containing a pavilion and a conductor of a water well, a device for aeration of water with an air duct and an annular tank that includes an upper aeration chamber with an inside washing device, a middle chamber for filter loading and a lower chamber for purified water. At the same time, an annular tank with a device for aeration of water is installed in the pavilion of the well, and the upper chamber in the lower part is communicated through a solenoid valve with a conductor in the flushing process, the solenoid valve being placed above the conductor in the full part of the annular tank, and the device for aeration of water made with radial windows in the lower part and equipped with a check valve placed under the radial windows.

 In addition, the flushing device is made in the form of an annular radial valve equipped with upper and lower bodies, and in the middle part a fixed float, and an annular radial valve is mounted movably in the upper and lower parts of the body and on the lower part of the device for water aeration, and in the upper parts of the radial valve together with the upper body are made radial windows coaxial to the radial windows of the device for aeration and the lower body is in communication with the lower chamber for purified water with and a water pipe.

 Also, the aeration device is equipped with an air valve connected to the upper part of the annular radial valve.

 It is advisable that the air intake part of the duct be installed above the pavilion of wells.

 It is also advisable that the upper housing of the washing device be equipped with sockets installed in alignment with the radial windows of the upper housing.

 In FIG. 1 shows a General view of the installation for water purification from iron and manganese.

 In FIG. 2 is a longitudinal section through an aeration device and a flushing device.

 The inventive installation for water purification from iron and manganese contains: pavilion 1, conductor 2 of the water well, a device for aeration of water 3 and an annular tank 4.

 The annular reservoir 4 includes an upper chamber 5 with a washing device 6, a middle chamber 7 for filter loading and a lower chamber 8 for purified water.

 The upper chamber 5 communicates with the inner cavity of the conductor 2 through the solenoid valve 9, which is installed in the inner cavity of the annular reservoir and above the conductor in the lower part of the upper chamber 5.

 The washing device (Fig. 2) includes an annular radial valve 10, upper 11, and lower 12 of the housing and in the middle part of a rigidly fixed float 13.

 The lower part of the aeration device is located inside the upper part of the upper chamber and is made with radial windows 14. The upper body 11 and the annular radial valve 10 are respectively made of radial windows 15 coaxially to the radial windows 14. The upper body 11 has conical sockets 16 with radial windows in alignment with the radial windows 14, 15. The lower housing 12 is in communication with the lower chamber 8 by a pipe 17 and is connected to a water pipe 18.

 The device for aeration of water includes an ejector 19, equipped with an air valve 20, which is spring-loaded and connected by rods 21 to the upper part of the annular radial valve 10.

 The device for aeration of water is equipped with an air duct 22, the intake part 23 of which is installed above the pavilion 1. In the lower part of the device for aeration, under the radial windows 14, a check valve 24 is installed.

 The upper chamber 5 is equipped with a plunger 25 and a pressure switch 26. Pavilion 1 is equipped with a control panel 27, including a timer for periodically turning on the solenoid valve 9.

 The inventive installation operates as follows.

 When the borehole pump is turned on, water is supplied under pressure to the ejector nozzle 19 and, passing through the ejector, is mixed with air sucked into the ejector and is aerated through the radial windows 14, 15 and conical sockets 16 into the upper chamber 5, radial windows 14, 15 and conical sockets 16 are placed in the annular direction and in the upper part of the chamber 5, which provides complete aeration of water with the simultaneous release of undissolved part of the air, which accumulates in the upper part of the upper chambers as they exit the conical sockets 16 5.

 The design parameters of the annular reservoir 4 and the capacity, especially of the upper chamber 5, are selected so that intensive separation of the air-water mixture occurs in the upper chamber, and that the annular reservoir 4 is also used as a pressure tank. Therefore, the plunger 24 is adapted to release only excess air.

 After aeration and separation, the aerated water, together with the flakes formed and the dry residue removed from the well, passes through the filter charge and the purified water is fed into the lower chamber 8, and from it through the pipe 17 and the housing 12 into the water pipe 18.

 In the process of washing by the command of the timer on the control panel 27, the solenoid valve 9 is turned on and the upper chamber 5 communicates with the conductor 2 and the contents of the chamber 5 flows into the conductor 2, and from it into the annulus of the well.

 As the water level in the chamber 5 decreases, the float 13 moves from the upper position to the lower one, while the radial windows 15 in the upper housing 11 and the outlet in the housing 12 for supplying purified water to the water pipe 18 overlap. The spring-loaded air valve 20 also moves to the lower position and blocks the access of air to the ejector 19, after which the injected water from the well through the ejector 19 enters the annular cavity 28, which in the lower position of the radial valve 10 communicates with the lower hollow part of the valve 10 and lower housing 12, and out of the housing 12 through the pipe 17 of the chamber 8, 7, 5, through the valve 9 in the conductor 2. There reverse circulation of raw water and produced a filter loading washing chamber 7 and the upper chamber 5.

 After the washing process is completed, the solenoid valve 9, by the timer command on the control panel 27, closes the valve cross-section and the pumped water through the ejector 19 and the chambers 8, 7 refills the chamber 5 and, as the ring valve 10 is filled, together with the float 13 moves to the upper position, blocking an annular cavity 27 from the lower inner cavity of the valve 10 and combining the radial windows 14, 15. The air valve 20 moves to the upper position and opens up air access to the ejector 19. The water treatment cycle resumes.

 The check valve 23 is activated when the downhole pump is turned off.
