How it works? | snegoplavilnye installation
Snegoplavilnye installation - a device for processing, or, in other words, the melting of snow and ice in an urban environment. Their use is essential in the winter season, when after heavy snowfall utilities take out tons of snow, which is required to dispose of. Today in Moscow, operated 48 fixed snegoplavilnyh points. How do they work - about it in today's issue!
The principle of operation of any snegoplavilnye installation based on the use of heat, resulting in the melting snow. The installation consists of a receiving hopper or the chamber, for heat generation unit and filtration system.
On the surface of any installation arranged grating on which trucks poured snow masses. In the first stage passes primary processing was brought snow - grille retains the large debris. The very same snegoplavilnye chamber is located inside the installation underground. It is there that the immediate process of forced snowmelt.
As an element for heating snegoplavilnye installation can use diesel or gas burners. Thus the hopper is divided into two compartments: a burner arranged in the first and the snow masses are accumulated in the second. Burners form hot gas streams and direct them through the heat exchanger, which melts the solid residues in the chamber.
After the formation of the melt water filters special mechanism remaining debris, and the liquid passes through the local water treatment plant, delaying sand and other fine particles and discharged into the sewer. This prevents clogging of sewers. Since the masses of snow and discharge them to completely dissolve in the melting chamber extends about 3-4 minutes. During this time, the plant is capable of processing up to 10 tons was brought precipitation.
There is also an easier way to snow melting - with the help of running water. Snow masses are discharged into a hopper filled with hot water in which it is naturally melted. In this snow is constantly mixed with the incoming flow of water, heated up to eighteen, and sometimes thirty degrees. As the reset snow mass in the melter, the water level in the hopper rises. The excess water passes through the vertical drain pipes and filters, and then discharged into the sewer network.
Stationary snegoplavilnye stations are often combined with the heating channels and sewers, to optimize equipment operation process.
In addition to fixed installations and mobile stations exist. They work on the same principles, but because of the size able to melt smaller amounts of snow: about 90 cubic meters per hour versus 300. The average time of a melting unit without refueling is about eight hours.
