Description

The utility model relates to devices for water treatment by distillation and can be used in chemical, medical and other industries where distillate with a high degree of purification is required.

To obtain water with a high degree of purification, there are known installations for producing twice distilled water — redistillators — distillers that purify water in two stages (two-stage purification).

Also known is a two-stage glass water distiller manufactured by HIMLABORPRIBOR software (Passport Mb 2.983.039 PS), which also contains condenser-coolers, heaters of 1 and 2 stages, a level regulator and control sensors. A disadvantage of the known installation is also the high energy intensity and large specific water consumption for obtaining a liter of purified water due to the use of a distiller with a heater and a condenser at each of the two stages of treatment.

The closest in technical essence and the achieved result is a distillation device described in PM No. 27587 Mcl. С02F 1/04, publ. 02.10.2002, containing a container for the source water, a distiller with an input of the source water, a refrigerator equipped with an outlet for draining the distillate, a mechanical cleaning filter, a membrane filter, a heat exchanger, pumps, water valves and taps in which the mechanical filter is connected through a water tap to plumbing. The known installation is less energy intensive, because the presence of filters instead of a distiller for primary purification of the source water allows you to use pre-purified (filters) water and use the heater and refrigerator for distillation only in the second stage, i.e. use less electricity.

A disadvantage of the known utility model is the design complexity and the need for frequent replacement of the membrane filter due to the low quality of the original tap water.

The task to which the proposed utility model is directed is to simplify the design of the installation and increase the service life of the membrane filter of the installation.

The problem is solved as follows.

A. Due to the installation of regulating devices in front of the filter block and after it, which allow controlling and regulating the water flow for evaporation and cooling of the distiller, which allows to get rid of the storage tank and the metering pump installed after it and, thus, connect the unit directly to water system, which simplifies the design of the installation and saves electricity.

B. By supplying the filter block installed between the mechanical cleaning filters and the membrane filter, a chemical cleaning filter, which increases the service life of the membrane filter.

The essence of the utility model is that a water distillation unit containing a filter block, a distiller consisting of an evaporator equipped with a feed water inlet and a condenser with a distillate drain outlet and a boost pump, is equipped with control devices in the form of a control valve with a pressure gauge. The filter unit consists of a mechanical cleaning filter, a chemical cleaning filter and a reverse osmosis (membrane) filter, sequentially mounted on the bracket. Providing the filtering unit with a chemical cleaning filter installed in front of the membrane filter allows extending the service life of the membrane of the latter. One of the adjusting devices is installed directly in front of the mechanical filter, and the second after the reverse osmosis filter. In this case, the input of the mechanical cleaning filter through the water tap and through the adjustment device is connected to the water supply, the filtrate output of which is connected to the input of the reverse osmosis filter, and the filter concentrate outputs are connected, in turn, through the adjustment device with the condenser cooling input, the cooling output of which is connected to sewage system.

Installation for water distillation is illustrated with graphic materials.

Figure 1 shows a General view of the installation;

Figure 2 - layout of the filters on the frame;

Figure 3 is a schematic illustration of the installation.

The water distillation installation comprises, connected to the water supply system through a water tap and a control valve 1 installed on the supply pipe, equipped with a pressure gauge, two mechanical filters 2, a chemical filter 3 associated with them, and a membrane reverse osmosis filter 4. Filters 2, 3 and 4 are sequentially mounted on a common bracket 5, rigidly mounted on the frame 6 (figure 1, 2). After the reverse osmosis filter 4, on the supply pipe, a second control valve 7 with a pressure gauge is installed. On the frame 6, a distiller is also placed, consisting of an evaporator 8 and a condenser 9 with a fitting 10. (Figs. 1, 3). Near the evaporator 8 there is a level gauge 11 with a level sensor designed to turn off the heating elements of the evaporator 8 when the water level drops below the permissible level. Booster pump 12 is located in the rear of the frame 6 in front of the reverse osmosis filter. In addition, an electric control unit 13 is installed on the frame 6, in the rear part thereof. To control the operation of the installation and control its operating parameters, an electronic control unit with a touch or button keyboard can also be used. The frame is closed by panels 14. On the rear panel there is a fitting 15 for condensate drainage (Fig. 3). The distiller is made of food grade stainless steel. The distiller can be made of quartz glass to facilitate additional visual inspection. The installation can be additionally equipped (if necessary) with a deionizer of water, which is installed on the bracket after the distiller and connected to the latter.

Installation for distillation of water works as follows.

Through an open water tap, tap water is supplied to the supply pipe of the installation through a control device - valve 1 with a manometer that controls the water supply to the filters for mechanical and chemical water treatment, respectively 2 and 3. After passing the preliminary mechanical and chemical treatment in the mentioned filters, the water is under pressure created by the boosting pump 12 enters the membrane reverse osmosis filter 4, where it is divided into two streams - the filtrate (purified water) and the concentrate.

The filtrate enters the level gauge 11 and then to the evaporator 8. A water level sensor is installed in the level gauge, which turns on the heating elements at a given water level in the evaporator 8. The distillate enters the consumer through the nozzle 10. The concentrate after passing through the reverse osmosis membrane 4 enters through an adjusting device (valve 7 with a pressure gauge), to cool the condenser and then merges into the drain through the nozzle 15.

The amount of water required for distillation and cooling is controlled by adjusting devices (valves 1 and 7).

The technical result is achieved due to the fact that in front of the filter block an adjustment device is installed, which is an adjustment valve equipped with a pressure gauge that controls the flow rate of water supplied to the distillation, which allows to exclude from the installation scheme the capacity of the source water dosing the flow of water for primary treatment, and a filter unit, in front of the distiller, a similar adjustment device is installed, the presence of which allows you to exclude from the circuit a dosing pump that controls the flow of water to evaporate and cool the distiller, and supplying the filter unit with a filter for chemical water treatment significantly extends the life of the membrane filter.

A - Due to the presence of two control devices that control the flow of water into the evaporator, one of which is installed directly in front of the mechanical cleaning filter, and the second after the reverse osmosis membrane filter, the installation can dispense with a source of water for dispensing water into the evaporator and without a second dispensing pump, which simplifies its design, in addition, the absence of a metering pump saves energy.

B. The supply of the filtering unit with a chemical cleaning filter installed directly in front of the reverse osmosis filter increases the service life of the membrane and also improves the quality of primary water treatment, which ultimately reduces the time for maintenance of the installation associated with cleaning the filters.

Thus, the task is solved.

At the production site of the company, a prototype of a water distillation installation “Analytical Water Quality Installations” was produced, type UPVA according to TU 9452-015-2221-3860-2009, and a registration certificate of the Federal Service for Supervision in Healthcare was received confirming compliance of this installation with the requirements for products medical equipment.
