Description

The device relates to the production of drinking water and can be used in the preparation of deep water from ponds, packaged in bottles or bags of various capacities.

A known method of producing Baikal drinking water according to the patent of the Russian Federation 2045478, Cl. C02F 1/00. 1995, according to which water is drawn through a deep water conduit from a layer of deep water defined by upper and lower horizons depending on the depth of the water body at the place of water intake. The pumping station is installed on the surface of the shore, which complicates water intake and requires significant energy consumption for water rise.

A known method for the production of bottled drinking water according to the patent of the Russian Federation 2108296, Cl. C02F 1/00, A23L 3/34, 1997. Water is taken in the areas of Lake Baikal with depths of more than 400 meters with a deep water conduit with an intake located from 25 to 100 meters from the bottom. The pumping station is installed on the surface of the shore, which complicates water intake and requires significant energy consumption for water rise. A vacuum system is needed to fill the pump case with water and start the pump station.

The closest (prototype) is the "Device for water intake from a reservoir" according to the patent for utility model RU 83260, IPC E03B 3/00, application 2008106535/22 of 02.19.2008.

A known device for collecting water from a reservoir includes a deep conduit with a head installed in the deep waters of the reservoir, a storage tank installed in the ground on the shore of the reservoir, and the second end of the conduit is installed in the storage tank below the water level in the reservoir.

Water flows into the tank by gravity due to the difference in water levels in the reservoir and in the tank.

Water enters the tank under pressure, but is inhibited in the tank and loses its kinetic energy. Part of the energy of the pump down pump must be spent on accelerating water from the tank to the pump inlet. In addition, the capacity is cumbersome and complicates water intake.

The technical task of the invention is the simplification of water intake, increasing water lifting, reducing energy consumption.

The technical result is achieved due to the fact that the device for deep water intake from the reservoir, including a deep conduit with a head installed in the deep waters of the reservoir, and the second end of the conduit is installed below the water level in the reservoir, equipped with a pump with a pressure pipe at the outlet, the pump inlet is installed at the second end of the conduit, and the conduit is installed below the water level in the pond.

The pump is installed on the shore of the reservoir.

The pump is installed in the waters of a reservoir.

The second end of the pipeline is installed above the water level in the reservoir.

The device is illustrated by drawings of FIG. 1 and FIG. 2, which shows a diagram of a device for abstraction of deep water from a reservoir.

The drawings indicate: head 1, deep conduit 2, second end 3 of conduit 2, pond 4, pump 5 with inlet 6 and outlet 7, bank 8, pressure pipe 9, second end 10 of pressure pipe 9.

Water is taken from Lake Baikal from a depth of 400 meters through head 1 and a deep water conduit 2, more than 3 km long, at the enterprise of LLC Baikalika, located in the village. Dry stream Slyudyansky district of Irkutsk region, produces drinking water of the first category "Baikalika".

The water conduit 2 along the entire length is set below the water level in the reservoir 4 and the deep water through the second end 3 of the conduit 2 by gravity and under pressure enters the inlet 6 of the pump 5, fills the crankcase of the pump 5 and reduces the force of the pump 5 to the water rise.

This reduces energy consumption, increases water lift and simplifies water intake.

When the pump 5 is installed onshore 8, simple monitoring and maintenance of the pump 5 (see Figure 1)

When the pump 5 is installed deep in the waters of the reservoir 4. deep water enters the inlet 6 of the pump 5, under significant pressure. Water is supplied to shore treatment 8 by pump 5 from the outlet of pump 7 via pressure pipe 9 through the second end 10 of pipeline 9 in significantly larger quantities than pump 5 can be pumped out on shore 8 (see Fig. 2)

The installation depth of the pump 5 is limited by the tensile strength of the deep conduit 2.

For example, at a pump installation depth of 5,100 meters, the external pressure of the water on the wall of the deep conduit 2 at the inlet 6 of pump 5 is 100 meters of water, or about 10 atmospheres.

The pressure drop on the wall of the deep water conduit 2 at the inlet 6 of the working pump 5 can be more than 10 atmospheres, since from within the deep water conduit 2, at the inlet 6 of the working pump 5, the negative pressure of the pumping water created by the pump 5 can be negative, less than atmospheric, if on the surface reservoir pressure is zero.

The increase in the pressure drop along the conduit 2 increases the pressure of the water at the entrance to the deep conduit 2 and increases the flow rate of the water in the conduit 2 and at the inlet 6 of the pump 5.

This reduces energy consumption and increases the amount of water taken from the reservoir 4.

The pressure at the outlet 7 of the pump 5, the length and location of the pressure pipe 9 are determined by the technical characteristics of the pump 5 and the needs of the intake system. Typically, the second end 10 of the pipeline 9 is installed on the bank 8 above the water level in the reservoir 4

The device is installed in the premises of the pumping station of the company Baikalika LLC.
