Utility Model Disclosure

The drawing indicates: runway (runway) 1, receiver 2, pre-filter 3, additional tank 4, pipeline 5, main tank 6, pump 7, crane 8, evaporator 9.

The device (a reagent recovery device from ice and snow, hereinafter also referred to as a reagent recovery device) consists of a receiver 2, a pre-filter 3, a pipe 5, an additional tank 4, a main tank 6 and an evaporator 9. The receiver 2 is a device for sewage collection. The receiver 2 is connected by a pipe 5 with a pre-filter 3, which, in turn, is connected in series with the corresponding pipe 5 with an additional tank 4. The additional tank 4, in turn, is connected in series with the evaporator 9, which is connected in series with the main tank 6. Pipeline 5 is made of a metal or plastic pipe of sufficient diameter for the correct operation of the device, based on the maximum possible flow rate and pressure of the liquid. The pre-filter 3, the secondary tank 4 and the main tank 6 are located in the housing, the remaining elements are connected to the housing. The case can be a metal box, soil, a special room, a box made of concrete slabs or other construction. The evaporator 9 and receiver 2 are located on the surface of the earth or mounted on the body, in an area free from pedestrian and vehicle traffic.

The pre-filter 3 contains cleaning mechanisms and filter materials for filtering wastewater. Additional tank 4 is a container of stainless steel or other suitable material. The volume of the additional tank 4 is not less than the maximum possible estimated volume of wastewater treated per season. The evaporator 9 is an outdoor pool, protected by a large metal mesh from the side of access to the bowl. The volume of the evaporator bowl 9 is equal to or less than the volume of the additional tank 4 (filling in several stages is possible). The main tank 6 is a container made of stainless steel or other suitable material. The volume of the main tank 6 is equal to the volume of the additional tank 4.

Utility Model Implementation

In the case of using the above elements and means, the utility model is implemented as follows. The receiver 2 is located along the runway 1 or another site on which it is necessary to systematically use the reagent in order to clear the ice and cover the snow. The receiver 2 can be made of gutters and a sewer collector, protected by metal grates from large debris. The gutters may be made of concrete or other suitable material. Then choose the appropriate location of the housing. The housing may be located underground or on the ground.

In the case of an underground location of the building. To a sufficient depth, in the casing, a pre-filter 3, an additional reservoir 4 and the main reservoir 6. A special room can be made of steel sheets with edges from steel corners for additional structural rigidity. A special room, if necessary, can have heating and lighting elements, a drainage pump and a manhole for access to individual elements of the reagent recovery device. An evaporator 9, a receiver 2 and, if necessary, an electric control panel are arranged on the housing or on another area of the earth's surface. After this, a serial connection by a pipeline 5 of all elements of the reagent recovery device is performed and the earth's surface is restored. Moreover, the receiver 2 is connected to the input of the pre-filter 3. The output of the pre-filter 3 is connected to the input of the additional tank 4. The output of the additional tank 4 is connected to the input of the evaporator 9. The output of the evaporator 9 is connected to the input of the main tank 6. The output of the main tank 6 is connected to the tap 8 on the surface of the earth.

In case of ground location of the hull. On the surface of the earth, in a region free of pedestrians and vehicles, they have a building. The enclosure can serve as a fence or a special room. A special room, in this case, can be built from any suitable building material (brick, foam block, concrete, steel, etc.). The special room, if necessary, can have heating and lighting elements, a hatch or a door for access to individual elements of the reagent recovery device, an electric control panel. After that, a pre-filter 3, an additional tank 4 and the main tank 6 are placed in the housing. The evaporator 9 is placed on the housing or in any other suitable place. After that, in the same manner as described for the underground location of the housing, a series connection of all elements of the reagent recovery device by a pipeline is performed.

The water supply between the elements of the reagent recovery device in the desired direction is carried out by the pump 7 or / and in a natural way with a sufficient inclination of the water pipes (pipeline 5) from a horizontal position. The volume of the evaporator (bowl) 9 may be equal to the volume of the additional tank 4 for one-stage filling or be less for filling in several stages. The evaporator bowl 9 is covered with a large mesh to prevent people and other foreign objects (debris) from entering the collected wastewater. Small debris can enter the evaporator 9 through the net. Therefore, the evaporator 9 may have an additional direct connection by a pipe 5 to the pre-filter 3 to separate newly caught small debris. The evaporator 9, if necessary, can be made inflatable or plastic with the ability to move. Thus, in the autumn-winter period, the evaporator 9 can be removed to another storage location. Pumps 7 and other electrical elements included in the reagent recovery device are connected with an electric cable to an electric control panel. The electric control panel is connected to an external power source. It should be noted that the evaporator 9, the electrical panel, the electrical connection, the housing, the crane 8 and the pipe 5 are arranged so that these elements do not violate the existing underground and above-ground communications, and do not interfere with the movement of pedestrians, vehicles and office equipment.

After applying the reagent, after a while, the ice and / or snow cover forms waste (melt) water. Wastewater containing the reagent enters the receiver 2 and then through the sewer into the pre-filter 3. Large debris (leaves, branches, etc.) remain on the metal grates of the receiver 3. Smaller debris and other substances other than constituents reagent, precipitated in the pre-filter 3. Next, the treated wastewater containing the reagent enters an additional storage tank 4. In this case, the output of the additional tank 4 is blocked in a suitable way (manual crane, automatic crane, etc.). When the summer season begins, exit from the additional tank 4 is opened. Wastewater containing the reagent from the additional tank 4 enters the evaporator 9. The output of the evaporator 9 is previously blocked in a suitable way. Under the influence of solar energy and wind, the process of evaporation of water from wastewater containing a reagent occurs. Upon reaching the initial concentration of the reagent open the outlet of the evaporator 9. The recovered reagent enters the main tank 6 for storage and reuse in the autumn-winter period.

Thus, the implementation of the device in the manner described above ensures the restoration of reagent used on runway 1 or other other surface for reuse.
