Description

A soil evaporator is proposed for measuring the intensity of evaporation from the surface of the monolith and equipped with a device that automatically maintains the constancy of the water level in the monolith.

A distinctive feature of the proposed evaporator is that it provides automatic continuous registration of the interactive evaporation system.

The proposed pachvenny evaporator is shown schematically in the drawing.

The evaporator is a reservoir placed into the soil /, filled, for example, with peat monolith 2 and provided with an air jacket 3.

The device that automatically maintains a constant water level in the monolith consists of a measuring cylinder 4, fixed. on a scale of 5, and a vessel 6 filled with water and also placed in the soil. The measuring cylinder 4, filled with water, is joined to the vessel 6 by means of a spring clip 7 attached to the bottom of the scale 5.

The upper end of the measuring cylinder 4 is closed, and a cork 8 with tubes 9 and 10 fixed on it is inserted into its lower tube, which communicates the vessel 6 with the measuring cylinder 4.

The end of the tube 9 is at the level of the water filling the vessel 6, and the end of the tube 10 is below the level of the water in the vessel 6. The tank / and the vessel 6, which are equal in height, are connected by the tube 11.

By filling the tank / monolith, water is poured into the tank until the water level in vessel 6 is equal to the surface of the monolith. In order to prevent water from evaporating from vessel 6, its surface is covered, for example, with an oil film.

As the moisture from the surface of myolith 2 evaporates, the amount of water in the tank / will decrease, which in turn will cause a decrease in the water level in the vessel 6. The former water level will be restored in the vessel 6 to maintain the level of the water in the tank / automatically.

When the water level in the vessel 6 is lowered, the cut off of the end of the tube 9 through it opens the access of air to the measuring cylinder 4, as a result of which the water through the pipe 10 flows from the cylinder 4 to the vessel 6. The overflow stops automatically after the water in the vessel 6 reaches its previous level, will close the end of the tube I and also auto415

magically renewed when the water level in vessel 6 decreases.

The amount of moisture evaporated from the surface of the monolith 2 in tank 1 is determined by the water flow from the measuring cylinder 4 by counting on a scale of 5.

For automatic continuous recording of the evaporation rate, the soil evaporator is equipped with a tap} 2, mounted on the upper closed end of the measuring cylinder 4 and connected to tube 13 with a barograph-type recording device 14 that continuously records the amount of evaporated moisture from monolith 2 as the level decreases; water in the measuring cylinder 4.

Subject of the invention: A soil evaporator equipped with a device for automatically maintaining the level of water in a monolith made in the form of a measuring cylinder at one end of the closed and at the other having two tubes, the end of one of which is at the level of the water in the vessel that feeds my water and the end of the other is lowered below a specified level, characterized in that, in order to provide automatic continuous recording of the evaporation rate, the closed end of the measuring cylinder is equipped with a tap connected by a tube istriruyuschim device type barographs.
