Description

The invention relates to devices for water purification, namely, devices for the purification of potable water to the parameters required when supplying mainly to washing and disinfecting machines, and can be used to prepare water for washing and disinfecting machines (MDM) endoscopic departments of medical organizations.

Washing and disinfecting machines are used in endoscopy to clean endoscopes between manipulations. These machines are very demanding on the pressure and flow of the supplied water, and sanitary rules and norms (SanPiN) impose strict requirements on the quality of treatment of this water.

The prior art installation for obtaining highly purified sterile water, containing a mechanical purification filter, a carbon filter, a two-stage reverse osmosis unit, the outlet of which is connected to the water supply system for injection, and a piping system, as well as an installation, is connected in series with a tap water source to the output of the reverse osmosis unit, a storage tank connected also to the washer and steam sterilizer (patent RU 38752, C02F 1/44, C02F 9/00, publ. 07/10/2004)

The known installation uses a reverse osmosis system, and, therefore, is not able to supply the installation-consumer (MDM) water at a constant required pressure. That is, such a device does not work in real time in flowing mode.

A known installation of water treatment for washing and disinfecting machines, including a filter block, which is connected in series to a pump inlet in series with a pump for increasing pressure, a water meter and a pressure reducer, and at the outlet in series with a storage water heater, and the installation is equipped with electric ballasts (patent RU 173452, A61L 2/02, publ. 08/28/2017). This installation is taken as a prototype.

The specified installation provides a high degree of water purification and pressure increase, but the description does not say anything about creating a debit (reserve) of water. Despite the fact that the unit has a storage type heater, this unit only works when water is being supplied to the inlet. The installation does not provide the creation of an accumulative buffer volume of water to compensate for its lack in real time.

The technical problem, which is aimed by the claimed technical solution, is to expand the technical characteristics and functionality of the device.

The technical result of using the utility model is to provide a constant predetermined pressure (flow) of purified water of a given outlet temperature, which creates a maximized flow of incoming water and ensures the creation of an accumulative buffer volume of water.

The specified technical result is achieved due to the fact that the water treatment installation for washing and disinfecting machines includes a flow-through antibacterial filter, which, through a piping system, is connected inlet in series with the first pump to increase the pressure at the inlet and with the water supply system, and at the outlet connected in series with a storage tank and with a second pump to provide outlet pressure. To control the operation of the installation, a control unit connected to the first electric pump to increase the inlet pressure and a control unit connected to the second pump to provide the outlet pressure are installed. To maximize the incoming water flow, mixing with water from the cold water supply system (CWS) of water from the hot water supply system (HWS) is applied, at a given temperature limit (not more than 27 ° C). For this purpose, an inlet piping system connected to a cold water supply system (CWS) is additionally equipped with a mixer and a flow cooler connected in series, which is connected at the outlet to a hot water supply system (WGC). The first pump installed at the inlet, connected with the water supply system, provides an increase in the suction pressure of water at the inlet to increase the volume of water from the water supply system, which allows to obtain a water volume of 15-20% more than its volume under its own pressure. The installation at the same time is guaranteed to create a given pressure (flow) of water at the outlet due to the accumulation of a buffer volume of water in the tank, which compensates for the lack of water in real time by accumulating it for the future. The reservoir is connected to a pump, which creates a given pressure (flow) of water at the outlet of the installation. The pump is connected to a washing and disinfecting machine (MDM). In the proposed installation, water is drawn from the water supply system and delivered to consumers (MDM) asynchronously.

Thus, the water treatment plant for washing and disinfecting machines includes a flow-through bacterial filter, which, through a system of pipelines, is connected in series at the inlet to the pump to increase pressure, then to the mixer, and then to the flow-through cooler, and, at the outlet, the filter, by piping system, connected to a reservoir for accumulating a buffer volume of water, at the outlet of which a pump is installed to provide pressure at the outlet, and the installation is equipped with control units associated with an insulating pumps.

The water treatment plant is mounted as a single structure, all of the components of which are interconnected not only constructively, through assembly operations, but also combined into a single structure, with a given set of features, which ensures the implementation of the installation of general functional purpose, allows to obtain the claimed technical result and provide the necessary operating conditions of the installation.

In FIG. 1 shows a functional diagram of a water treatment plant. The water treatment plant for washing and disinfecting machines consists of a flow-through antibacterial filter 1, which, through a piping system 2, is connected at the inlet to a pump for increasing pressure 3 and a mixer 4. The mixer 4 is connected to a hot water supply and, through a flow cooler 5, to a hot water supply. At the output, the filter 1 is connected in series with the reservoir 6 and the pump 7. To control the device, control units are provided.

The device operates as follows. Water from the cold water supply pipe (CWS) enters through the pipe 2 to the mixer 4, which simultaneously receives water from the hot water supply system (CW), passing through a flow cooler 5, which cools the water to a predetermined temperature limit (no more than 27 ° C) . This makes it possible to maximize the incoming water flow, through the use of mixing with water from the cold water supply system (CWS) of water from the hot water supply system (HUW). From mixer 4, water enters through filter 3 (for example, a Fluid-o-Tech pump) to the inlet of filter 1. Pump 3 provides an increase in the suction pressure of the water and an increase in the debit of water from the water supply system, which makes it possible to obtain more water by 15-20% than its debit is under its own pressure in the water supply system. Passing through a flowing antibacterial filter 1 (filter rating of 0.01 μm), water is purified. Then, the water through pipeline 2 enters the reservoir 6, where the buffer reserve volume of water is accumulated, which can compensate for the lack of water in real time, and also creates a given pressure (flow) of water at the outlet. Then, the water through the pump 7, which creates the required pressure at the outlet of the installation (for example, the Scala pump, Grundfos), enters the washing and disinfecting machines (MDM). To control the installation, control units are used.

For the used antibacterial filter 1, the possibility of backwashing (regeneration) is provided, which prolongs its service life and reduces the total cost of maintenance of the installation.
