Description

The invention relates to stationary devices designed for the disposal of solid atmospheric precipitation removed from urban areas, and can be used to forcibly melt the collected snow mass, ice and further use of the obtained melt water for irrigation during positive temperatures, fire fighting and other household needs. This ensures the saving of drinking water quality, often used for these needs.

A known design of a snow melter, including a melting chamber made in the form of an enclosing building structure of a closed volume, a piping system for supplying coolant and its removal after cooling, an intensifier of snow melting and an additional chamber. The building structure is equipped with loading gates from one end of the chamber and has a base of porous concrete. The piping system includes an injection distribution system of perforated pipes for supplying hot air, placed under the specified base, and an air intake perforated pipe installed in the upper part of the melting chamber. The intensifier is made in the form of infrared emitters and is also installed in the upper part of the melting chamber. An additional chamber is installed outside the melting chamber and contains a power plant connected to a discharge distribution system and an air intake perforated pipe. The snow melter is installed above the sediment-overflow pit connected to the sewer well (RU patent No. 2226591, IPC E03F 5/02, E01H 5/10, 2004).

The disadvantage of this design is the inability to use the obtained melt water for irrigation during periods of positive temperature, fire fighting and other household needs, and, consequently, unstoppable energy costs for the forced melting of snow mass and ice.

The closest technical solution is a method of forced snow melting and a device for its implementation, including a bath for receiving and melting snow mass, a device for heating the water contained in the bath with combustion products of liquid or gaseous fuel, a pump for taking water from the bath and feeding it through nozzles for irrigation of snow mass and a device for removing water from the bath, divided by a perforated partition, which can be made in the form of a grid, into two compartments, one of which is made with the possibility of the load of snow mass into it, and in another there is a device for heating water, while the suction pipe of the pump is located with the possibility of taking water from its surface layers (RU patent No. 2173744, MGZh E01N 5/10, E01C 11/26, 2001 )

The disadvantage of this invention is the complexity of the design and the technological cycle, as well as the limited possibility of using heated melt water - only in heat supply systems.

The technical result achieved by the present invention is the ability to quickly use the resulting melt water for irrigation during positive temperatures, fire fighting and other household needs. This ensures that drinking-quality water is saved and, accordingly, energy costs for the forced melting of snow mass and ice are partially paid off.

This technical result is achieved by the fact that the device for utilizing solid atmospheric precipitation (hereinafter referred to as the “Device”) consists of a boiler house, a supply, a discharge and a suction pipe, a process chamber, a reception and melting chamber for snow mass and ice, as well as a storage tank.

In Fig.1 - "Device" (general view), in Fig.2 - "Device" (in plan).

The proposed device consists of a boiler house (1), a circulation heating circuit, equipped with a solid fuel-fired water heating boiler (2), a supply pipe (4), a discharge pipe (6), a centrifugal pump (3) and an expansion tank (5), a suction pipe (15) equipped with a strainer (14), as well as a technological chamber (9) equipped with an access hatch (11) and a ladder (7), a reception and melting chamber for snow mass and ice (10), equipped with a receiving grill (12 ), plate radiator (8) representing a curved steel pipe on which metal plates are mounted, an accumulation tank (19) with a receiving chamber (18) equipped with a centrifugal pump (16) and an access hatch (17).

"Device" works as follows. A small amount of water is poured into the receiving and melting chamber of snow mass and ice (10) in order to increase the efficiency of heat transfer. The water level should be higher than the location of the plate radiator (8). Next, the circulation heating circuit is started by switching on the water heating boiler (2) and centrifugal pump (3). Water circulating along the circuit heats the plate radiator (8). The chamber for receiving and melting snow mass and ice (10) is filled by unloading dump trucks (20). Snow mass and ice, falling through the cells of the receiving grate (11), after unloading a certain number of dump trucks, fills the chamber (10). Objects remaining on the grate that are larger than the size of its cells are deleted by the operator. Under the influence of the elevated temperature created by the plate radiator (8), the process of melting snow mass and ice occurs. As the chamber (10) is filled with melt water, the pump (16) is turned on and the heated melt water is cleaned in the strainer (14) and enters the storage tank (19) through the intake chamber (18) through the suction pipe (15). Inspection and periodic cleaning of the chamber (10) and the strainer (14) from contaminants coming with snow and ice is carried out subject to access to the chamber (10) through a waterproof hatch (13) that opens from the chamber (9).

The result of the “Devices” operation scheme is the effective utilization of solid atmospheric precipitation, purification of the obtained melt water and the possibility of its further use from the storage tank for irrigation during positive temperatures, fire fighting and other household needs. This saves potable water.
