Description

The technical field to which the utility model belongs.

The utility model relates to purification equipment, and more particularly, to installations for pressureless aeration of water, including a storage tank having an inlet for supplying purified water with an electromagnetic valve for supplying purified water, a sprayer of purified water located inside the storage tank, the storage tank having an outlet a nozzle for the outlet of purified water connected to a pump located outside the storage tank, while the installation has water level sensors connected with a control unit, which is also connected to a solenoid valve for the supply of purified water. With a high content of ferrous iron, manganese, and hydrogen sulfide in the source water, the installation can be used in household water treatment systems for the non-reagent removal of hydrogen sulfide and other gases dissolved in water, saturation of water with atmospheric oxygen, and acceleration of the oxidation processes of the elements indicated above followed by filtering in clarification plants / iron removal

The level of technology.

For water purification with a high content of divalent iron, manganese and hydrogen sulfide, plants for pressureless aeration of water are used to saturate the source water with atmospheric oxygen by spraying it in an oxidizing tank (contact tank). Thus, a prior art installation for non-pressure aeration of water, comprising a storage tank having an inlet pipe for supplying purified water with an electromagnetic valve for supplying purified water, a sprayer of purified water located inside the storage tank, the storage tank having an outlet pipe for the outlet of purified water connected to a pump located outside the storage tank, the installation has water level sensors connected to a control unit, which is also connected to solenoid valve for the supply of purified water.

See the description of the non-pressure aeration unit of the manufacturer NPP World Water Technologies LLC, a link to the Internet http://wwtec.ru/index.php?id=478.

In it, the control unit is made in the form of a box attached to a storage tank, in which a level control relay is located, connected to level sensors.

 This installation is the closest in technical essence to the claimed utility model and is taken as a prototype to the proposed utility model.

The disadvantage of this installation is the low reliability of the installation. Indeed, the installation described in this prior art is not assembled in a single housing, there is no fittings that will automatically shut off the water supply in the event of a failure of the electromagnetic valve and, as a result, overfilling of the tank, as well as electrical wiring from actuators, such as an electromagnetic valve, not fixed and not protected (cable channel, corrugation), also the power cable of the installation has the same disadvantages.

All this complicates the installation and dismantling of such an installation. Also, there is no single shield (panel) for controlling all processes and emergency situations of such an installation, nor is there a light indication of the processes and emergency operation modes of such an installation.

There is no way to program such an installation to perform many operations related to protecting the operation of the installation to expand its functionality (for example, to automatically protect against leakage to the floor, protect against overflow, protect against dry running of the pump, protect against the lack of water supply for more than 90 minutes, etc. ), which leads to the fact that such an installation is characterized by low reliability. In addition, the disadvantage of this installation is the lack of ease of operation of the installation. This is due to the complexity of installation and management of such an installation. Also, the installation is not mobile (it does not have the ability to move on wheels), there is no booster pump station, which is the main element of the pressure-free aeration unit (retrofitting, additional installation space, electrical connections and materials for strapping).

In addition, there is no thermal protection of the tank, which can be very condensed.

Thus, the problem to which the real utility model is aimed is to increase the reliability of the installation.

According to figure 1, the installation for pressureless aeration of water includes a storage tank 1 having an inlet pipe 2 for supplying purified water with an electromagnetic valve 3 for supplying purified water. The tank 1 has a sprayer 4 of purified water located inside it, and the storage tank 1 has an outlet pipe 5 for the outlet of purified water, connected to a pump 6 located outside the storage tank.

A centrifugal pump can be used as a pump.

The controller 10 also optionally has a module 13 for protecting the solenoid valve of the cleaned water supply from “lack of filling”. The controller 10 has optional analog and digital inputs 14 for connecting additional equipment.

Panel 11 light indication of processes and emergency modes can be made in the form of a display, which in turn can be made color and / or touch.

The controller 10 can be connected to the module 15 for storing a database of installation parameters, including an event log, an alarm log, and a statistics collection log.

The controller 10 may include a remote access communication module 16.

The housing 1 of the storage tank may have a means 17 of thermal protection of the storage tank from condensate. As such a means can be used, for example, foil foamed foam or rubber thermal insulation K-Flex

The controller has a module 18 emergency stop the pump in case of emergency. Module 18 is connected to the pump 6.

Vector g denotes the direction of gravity.

In addition, the automation unit of the pump 25 is shown, which can protect the pump 6 from "dry running".

At high concentrations of iron, manganese and hydrogen sulfide in the initial water, to accelerate the process of their oxidation, a bubbling aeration system can be installed inside the storage tank 1, including:

- fine bubble aerator 26 and

- low-pressure air compressor 27 controlled by the controller 10.

Implementation of a utility model.

Installation for pressureless aeration of water is used as follows. (A non-limiting example of a utility model is given).

Stage A1. The water being purified from ferrous iron, manganese or hydrogen sulfide is fed through the pipe 2 to the storage tank 1, where its maximum and minimum level of filling is maintained.

Stage A2. The water supply (opening / closing of the input solenoid valve 3) is controlled by the controller 10 according to the signals received from the level sensor 8

Stage A3. A sprayer 4 is installed in the storage tank 1, for which spray nozzles can be used, which make it possible to obtain a finely atomized stream of water, i.e. water flow resulting from crushing a water jet into droplets whose arithmetic mean diameter is 150 μm or less.

Creating a high-speed drip stream is organized in two ways:

- single-phase flow - due to the mechanical energy of the water supplied to the nozzle under pressure, using hydrodynamic effects, including cavitation. In this case, the storage tank 1 can be considered as a hollow (nozzle) atomizing absorber, which is a column or chamber in which air moves, encountering water sprayed onto droplets using nozzles (sprayers);

- two-phase flow - due to the kinetic energy of the air supplied to the atomizer 4 under pressure, by mixing with water in specially designed mixing and nozzle devices. In this case, the storage tank 1 can be considered as a high-speed ramjet spray absorber in which the liquid is sprayed due to the kinetic energy of the air flow moving at a high speed.

It is also possible to create a high-speed fine-sprayed stream due to the principles of crossing jets and centrifugal effects in specially designed nozzle devices. Additionally, it is possible to carry out aeration using a compressor that feeds air into the water column through fine-bubble aerators. Due to this, the water in the oxidation tank-aerator is mixed, which accelerates the oxidation of iron and gases.

At high continuous costs, in order to accelerate the oxidation of iron, manganese and hydrogen sulfide or the need to adjust the pH of the water at the entrance to the storage tank 1, a proportional dosing system of reagents (biocide, coagulant, acid or alkali solutions) is installed.

Stage A4. Since a rupture of a jet of water occurs in a pressureless aeration station, a pump 6 (or pump station) is installed after it to increase the pressure to the required value (3.5 - 6 atm).

Stage A5. Depending on the configuration, the pump 6 is protected from “dry running” either by the controller 10 or by the pump automation unit (type Brio2000) 25, which makes the unit operation more safe and trouble-free.

Using the panel 11 carry out light indication of processes and emergency conditions.

Using module 12, it is possible to protect against overflow and leakage of water to the floor, depending on which sensor the alarm came from, that is, either pump 6 stops, or an electric ball valve 22 automatically shuts off.

Using module 13, it is possible to protect the solenoid valve for supplying purified water from “lack of filling” (overheating).

Using module 16 provide the ability to exchange data for remote access with the remote computer 19.

Using means 17 provide the possibility of thermal protection of the storage tank 1 from condensate.

The above embodiments of the utility model are exemplary and allow you to add new options or modify the described.

Industrial applicability.

Installation for pressureless aeration of water can be carried out by a specialist in practice and, when implemented, ensures the implementation of the declared purpose. The feasibility in practice follows from the fact that for each feature included in the utility model formula based on the description, the material equivalent is known, which allows us to conclude that the criterion of “industrial applicability” for the utility model and the criterion of “completeness of disclosure” for the utility model are met.

The pilot operation of the proposed installation showed that it is possible to assemble the entire installation as a single device, which increases the convenience of installation, connection, maintenance, repair, as well as possible dismantling, and also increases the convenience of controlling such a installation due to the presence of a multifunction controller and the presence of a light indicator panel of processes and emergency modes. At the same time, the reliability of the entire installation increases due to the fact that it is a single device, external connections are minimized, everything can be immediately assembled and tested in the factory.

In addition, the convenience of maintenance, the convenience of replacing the actuators that have spent their resources, and the convenience of controlling all technological processes inside the pressure-free aeration unit from a single center (control panel / console) to which all executive electric devices are connected, are increased.
