Description

The utility model relates to devices for water treatment, namely, devices for the post-treatment 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 of endoscopic departments of medical organizations .

The prior art device, which includes two series-connected filter housings with filter elements installed for mechanical and antibacterial cleaning, pressure gauges at the inlet and outlet of water lines, a bracket for wall mounting and a device for controlling the cycle of disinfection of water lines (Instruction. " ASP Automatic Endoscope Reprocessor (AER). Advanced Sterilization Products ^® , 4 Water Filtration System ”, p. 34, November 2006). The specified device is taken as a prototype.

In the known device, with self-disinfection, the water lines are filled with a disinfectant solution, which merges after a certain exposure time. In this case, the presence of uncontaminated sections of the internal surfaces due to the presence of air jams is possible. In addition, it is possible incomplete filling with a disinfectant of all internal cavities of the device. When filling the filter housings with disinfectant concentrate, there is water in the remaining internal cavities, and in the absence of constant circulation, uniform mixing of the liquid to the desired concentration of the active substance does not occur. In view of this, the quality of disinfection suffers. Part of the inner surfaces may remain uninjured.

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 enable the installation, which is a single mobile unit, to carry out a series of operations for water treatment of water, namely:

- multistage water treatment with final bacterial treatment (bacterial filtration up to 0.2 microns);

- water heating with delivery to the consumer through an adjustable thermostat of bacterially purified water of a given temperature (up to + 55 °) with an accuracy of 1 °;

- increasing the pressure of the supplied purified and heated water (increase by 0.6-1.5 bar) in order to compensate for the pressure loss on the filters;

- the presence of a self-disinfection system for the entire device, necessary to maintain the cleanliness of the internal surfaces;

- mobility of the water treatment plant due to the fact that the entire device is assembled in a single unit, allowing it to be moved to connect to consumers in medical organizations.

The specified technical result is achieved due to the fact that the water treatment installation for washing and disinfecting machines that perform high-level disinfection of medical devices includes filter housings with filter elements installed in them, pressure gauges and a control device, and filter housings with individual pressure gauges are combined into a single filter block, which, through a piping system, is connected at the inlet to a pressure reducer, a water meter and a pump to increase the pressure, and at the outlet It is necessary with a storage water heater, adjustable thermostat and control antibacterial filter. To control the installation provides electric ballasts. Additionally, the unit is equipped with a self-disinfection unit for the entire system, including a pipeline and a recirculation pump. The unit is mounted in the housing, in the form of a spatial floor frame with hinged external panels, with the possibility of its movement.

The above set of features allows to obtain the claimed technical result and to provide the following operating conditions of the installation.

The storage water heater makes it possible to obtain the outlet temperature required for washing and disinfecting machines. The filter unit with individual pressure gauges provides the ability to individually indicate the pollution of each stage of the filter unit (by pressure gauges) and selectively replace the filter elements. Also, the filter unit makes it possible to vary the number of stages of filtration, depending on the requirements of the consumer and the quality of water supply at the consumer, by installing different filter elements. The pressure increase pump allows compensation of pressure loss as the filters become dirty, which allows maintaining the pressure at the inlet of the washing and disinfecting machines at the level necessary for reliable operation. A pressure reducer protects the unit against water hammer. The filter unit, together with the control antibacterial filter, provides the possibility of high-quality antibacterial water treatment.

The self-disinfection unit, equipped with a recirculation pump, which creates a constant flow of disinfectant solution throughout the system, thereby allows contact of all internal surfaces of the installation with the disinfectant solution and their reliable disinfection. In this case, the possibility of the presence of untreated sites is completely excluded.

Constructive mixing in a single device of a heater, a filter unit, a thermostat and a control filter made it possible to treat all internal surfaces of all components of the installation with a guaranteed processing quality in one self-disinfection cycle. And also, due to the fact that the installation is assembled in a single unit and placed in the case in the form of a floor spatial frame, the mobility of the water treatment plant is ensured, allowing it to be moved for connection to consumers in medical organizations.

In FIG. 1 is a functional diagram of a water treatment plant; FIG. 2 is a front view, in FIG. 3 is a left view, in FIG. 4 is a right view.

The water treatment plant for washing and disinfecting machines that perform high-level disinfection of medical devices consists of filter housings 1, with filter elements installed in them, with individual pressure gauges 2, combined into a single filter unit, which, through a piping system 3, is connected at the input to a pump for increasing pressure 4 with an integrated flow sensor 5, a water meter 6 and a pressure reducer 7, and at the outlet, in series with a storage water heater 8, adjustable by thermostat 9 and control an anti-bacterial filter 10. An electric ballasting device is provided for controlling the device 11. The installation is equipped with a self-disinfection unit for the entire system, including pipelines 3 and a recirculation pump 12. The installation is mounted in the housing, in the form of a floor spatial frame 13 with hinged external panels, with the possibility of its movement.

The device operates as follows. Water from the cold water supply pipeline flows through the pipeline to the filter unit and passes through the filters 1, sequentially cleaning from mechanical impurities, cleaning from hardness salts (if necessary) and antibacterial cleaning. Multistage water treatment with final bacterial treatment allows for bacterial filtration up to 0.2 microns. Then the water enters the storage water heater type 8 and is heated to the required temperature, which ensures the efficiency of the washing and disinfecting substances in washing and disinfecting machines. Water heating, with the issuance of bacterially purified water to the consumer, is carried out up to 55 ° C with an accuracy of 1 ° C. If necessary, using a pump to increase the pressure 4, produce a pressure increase of the supplied purified and heated water by 0.6-1.5 bar.

The disinfection mode of the device is as follows. When changing the filter elements, the housing of the first filter of the filter unit is filled with a concentrated disinfecting solution, and the recirculation pump 12 is turned on for a predetermined time for forced circulation of the solution through the system. After processing, the disinfectant solution is drained into the sewer. In this case, all pipelines 3 are effectively disinfected, as well as a water heater 8, filters 1 and filter 10.
