Definitions
- the invention relates to self-contained membrane purification devices with the possibility of recirculating and / or desalting liquid, mainly water from various sources for domestic and / or drinking water supply and is intended for use in domestic conditions, public institutions, in summer cottages and garden plots.
- Membrane liquid purification devices are known and widespread. Most of the known devices for membrane liquid purification are permanently mounted to a liquid source, which limits the applicability of these systems in conditions where there are several liquid sources or the liquid source is not constant, as well as in cases where operating conditions do not allow the device to be located in the immediate vicinity of the liquid source.
- Semi-autonomous membrane liquid purification devices are also known from the prior art, which have a means of dynamic connection to a source of the initial liquid. These devices also cannot be used in cases where it is impossible to locate the device near the source of the initial liquid or when it is required to move the device during operation, which is a limitation for the use of these devices and a significant drawback. Autonomous membrane liquid purification devices do not depend on the number of possible sources of the initial liquid and the location of the liquid source, which makes such devices more versatile and expands the area of their possible application.
- the specified membrane liquid purification device includes a container for a source liquid, equipped with a liquid outlet, which is located at the bottom of the container for a source liquid, a liquid supply unit including a pressure increasing means, a liquid supply line and a blocking means made in the form of a liquid level indicator in the container for source liquid, liquid purification unit, container for clean liquid and drain line for drainage liquid.
- the container for the initial liquid is connected to the liquid supply unit through the liquid outlet and has a functional connection with the liquid supply unit through the liquid level indicator of the blocking means located in the container for the initial liquid.
- the outlet of the liquid supply unit is connected to the inlet of the liquid purification unit, which has two outlets: a clean liquid outlet connected to the clean liquid tank and a drainage liquid outlet connected to the drainage liquid drain line.
- the device works as follows. The initial liquid from the container for the initial liquid through the liquid outlet enters the liquid supply unit and then to the liquid purification unit. In the liquid purification unit, the liquid purification process is carried out, while the clean liquid enters through the clean liquid outlet of the liquid purification unit into the container for the clean liquid, and the drainage liquid through the drainage liquid outlet of the liquid purification unit is fed to the drainage liquid drain line and is discharged from the system.
- the liquid cleaning process continues until the liquid level in the source liquid container reaches the level at which the liquid level indicator of the blocking device is located, after which the fluid supply unit is turned off.
- the design of this device does not provide for the ability to regulate the degree of use of the initial liquid, since the system does not provide for the possibility of returning the drainage liquid to the container for the initial liquid, which is ineffective in terms of the consumption of the initial liquid to obtain a clean liquid and is a disadvantage of this system.
- a device for membrane liquid purification is known according to US patent 8,945,377 [IPC C02F 1/44, B01D 61/10, C02F 1/00, B01D 61/08, B01D 61/12, publ. 02/03/2015], consisting of a tank for the source and drainage liquid, separated by a horizontal partition with an opening, an element for taking liquid from the indicated tank, a means for creating a pressure, a liquid purification unit, a tank for the purified liquid and a line for returning the drainage liquid to the tank for the source and drainage liquids.
- the liquid withdrawal element is located in the reservoir for the source and drainage liquid above the partition.
- the inlet of the pressure generating means is connected to the liquid withdrawal element, the outlet of the pressure generating means is connected to the inlet of the liquid purification unit.
- the clean fluid outlet of the fluid purification unit is connected to the clean fluid container.
- the drain fluid outlet of the fluid purification unit is connected to the inlet of the drain fluid line.
- the drainage fluid line is made in the form of a tube, at least part of which is located inside the reservoir for the source and drainage fluid, while the outlet of the drainage fluid line is located in the reservoir for the initial and drainage fluid below the partition.
- the initial liquid After the means for increasing the pressure, the initial liquid enters the liquid purification unit, where the liquid is purified.
- the clean liquid enters the clean liquid container through the clean liquid outlet.
- the drainage liquid through the drainage liquid outlet through the drainage liquid line returns to the reservoir for the initial and drainage liquid, while displacing the initial liquid through the liquid withdrawal element to the inlet of the pressure increasing means and further along the cycle.
- the main disadvantage of this device is that the liquid withdrawal element is located so that the liquid is withdrawn from the middle layers of the liquid in the containers for the initial and drainage liquid.
- a device for membrane purification of a liquid is known according to RF patent 2597605 [IPC B01D 17/12, B01D 37/00, B01D 61/00, B01D 61/12, B01D 63/00, publ. 09/10/2016], selected by the applicant as the closest analogue.
- the device for membrane cleaning of a liquid according to the patent of the Russian Federation 2597650 consists of a container for a liquid, a means for taking out a liquid, a means for increasing pressure, a block for cleaning a liquid, a container for a clean liquid and a liquid drain line.
- the container for the liquid is connected to the the inlet of the pressure increasing means, the outlet of which is connected to the inlet of the liquid purification unit.
- the liquid purification unit has a clean liquid outlet connected to a clean liquid container and a drainage liquid outlet connected to a drain line that is connected to a liquid container.
- the device for membrane purification of liquid operates as follows. The liquid container is filled with the initial liquid to the initial level. From the container for the liquid through the liquid withdrawal means, the initial liquid enters the inlet of the pressure increasing means, from where it enters the inlet of the liquid purification unit.
- Two liquid streams leave the liquid purification unit a stream of clean liquid, which enters the container for a clean liquid; the drainage liquid flow, which is returned to the liquid tank through the drainage line, thus, the liquid cleaning process with recirculation is realized.
- the liquid purification process continues until the liquid level in the liquid container reaches a predetermined level.
- the liquid sampling means At least one air bubble will enter the inlet of the pressure increasing means, which leads to stopping the liquid cleaning process and turning off the device.
- the main disadvantage of the closest analogue is that the liquid withdrawal means is located in the lower (in the bottom) or middle part of the container, thus, liquid withdrawal occurs from the lower or middle layers of the liquid, where the composition of the liquid is most uneven due to the return of the drainage liquid, thus
- the content of impurities in the liquid which enters the inlet of the pressure increasing means and then to the inlet of the liquid purification unit during the filtration process, changes unevenly, which does not allows the liquid purification unit to operate in an optimal mode, which reduces the efficiency of the fluid purification process.
- the objective of the invention and the technical result achieved with the use of the invention is to develop a device for membrane purification of a liquid, in particular drinking water, with the possibility of increasing the efficiency of liquid purification by achieving a uniform change in the composition of the filtered liquid.
- the device for membrane cleaning of a liquid consisting of a container for a liquid, a liquid withdrawal device, a pressure increasing device, a liquid cleaning unit, a clean liquid line and a drain line, is configured to withdraw liquid from preferably the surface layer of the liquid in the liquid tank and automatic stop of the liquid cleaning process when the liquid level in the liquid tank reaches a predetermined value and / or after the required volume of liquid is cleaned, while the liquid withdrawal means is configured to move vertically when the liquid level in the liquid tank changes and is made in the form of a flexible tube and a floating element or in the form of a flexible tube, a hinge mechanism, a rocker arm and a floating element, while the floating element can be additionally equipped with stops of a given height or stops of an adjustable height, as well as a floating element mo can be additionally provided with a rim and / or screen made with the possibility of separating the liquid taken from the liquid container from the drainage liquid, while the liquid container may additionally contain protrusions
