Description

The utility model relates to devices for providing forced melting of snow mass collected by special vehicles from city streets and roads, in particular, to installations in which the dumped snow mass is subjected to various influences, mechanical, thermal, etc. to accelerate its melting and subsequent distribution of melting products for various purposes.

Currently, there is a problem for a big city in the disposal of a huge amount of snow mass in the winter season. The increased requirements of the city authorities for the cleanliness of the streets, in particular, associated with a sharply increasing flow of vehicles, make us seek new opportunities to accelerate the process of snow melting in specially designed installations.

Known RF patent No. 2173744 from 04/13/2000, disclosing a method and apparatus for forced snow melting. In the aforementioned well-known invention there is a bathtub divided into two compartments, one of which is designed for receiving snow, and the second contains water that is heated with the help of fuel burners, and heated water is taken and fed to the snow mass by a feed system pump. The supply of heated water to the snow mass has a positive effect on the efficiency of the process in the installation.

The compartments are separated by a grid, and the products of the snow melting process are distributed depending on their purpose.

In this known installation there are two separate systems: heating water and supplying it to the snow mass. Elements of the fuel system are installed in this system, including the fuel source necessary for the operation of the installation.

This system has certain disadvantages, primarily due to the presence of a multi-element fuel system. The fuel system scheme used is rather complicated, involving the presence of a fuel tank, pipelines, and special fuel burners installed directly in the bathtub, where snow collected from the streets melts, which leads to contamination of the burners and complicates the operation of the snow melting unit.

Also known is a snow melting apparatus comprising a bath divided into compartments interconnected, one of which is intended for collecting snow, the first heating means for heating the melt water of the bath, and the second heating means associated with a heat source, as well as a system for supplying heated water to the snow collection compartment, which includes a pump installed in the bath and connected by pipelines to a distribution manifold for supplying heated water, wherein said first and second means for heating are installed claimed ensuring heat transfer from the second to the first means and represent, respectively, the first and second heat exchange devices (see. Russian patent №2339759).

This installation is free from the disadvantages of the previous known device, it lacks a complex fuel system and there are no fuel burners installed in the snow bath. This installation is economical because uses the return and / or direct lines of urban heating networks as a heat source.

However, quite often there are situations when the use of urban heating networks is impossible or impractical, because they are located at a considerable distance from the snow melting plant and laying pipes to it is difficult and expensive.

The objective of the present invention is to provide a installation for melting snow, which is compact, which can be used away from urban heat pipelines with sufficiently high efficiency.

In addition, the objective of the present invention is to provide a snow melting apparatus having a low cost, having simplicity and reliability in operation, providing the possibility of its widespread use in various settlements.

To solve these problems, it is proposed installation for melting snow, containing a bath divided into interconnected compartments, one of which is designed to collect snow, the first heat transfer means for heating, designed to heat the melt water of the bath, and the second heat transfer means for heating associated with a heat source, as well as a system for supplying heated water to a compartment for collecting snow, which includes a pump installed in the bath and connected by pipelines to a distribution manifold for supplying heated water, m, said first and second means for heating are installed to provide heat transfer from the second means to the first, and said heat source is a fuel device that heats the second heat exchange means for heating.

In addition, in the installation, the first heat exchanger is installed in the compartment for collecting snow in its lower part.

Additionally, in the installation, the pipelines from the bath pump pass through the first heat exchanger with the formation of its branches.

In addition, in the installation, the specified bath pump is installed in the compartment farthest from the snow collection compartment, and these compartments are separated by partitions with holes located at different levels with the formation of a labyrinth for the flowing melt water to ensure its purification before entering the pump.

The essence of this utility model will be more clear when reading the following description of the preferred installation options, taking into account the accompanying drawings, in which

Figure 1 - is a schematic view of one embodiment of the inventive installation.

Figure 2 - is a schematic view of another embodiment of the inventive installation.

Installation 1. for melting snow contains a bath (reservoir) 2, divided into a number of interconnected compartments. Compartment 3 is designed to collect snow brought and dumped into it by vehicles. Bath 2 is connected to the line 4 discharge of melt water supplied, for example, to treatment facilities. Line 4 is designed in such a way as to provide an upper limit level of water in the bath. Installation 1 includes a first heating means for heating melt water, which may be in the form of a first heat exchange device 5, and a second heat exchange means 6 for heating associated with a heat source. The first and second heat exchangers 5 and 6 are interconnected by a looped line 7 in which the pump 8 is installed. The heating station 9, in which the second heating means 6 is installed, is connected to a heat source.

In the farthest from the compartment 3 of the bath compartment 10, a pump 11 is installed, providing a supply of warm water to the snow discharged into the compartment 3. The pump 11 takes water from the compartment 10 and directs it through the pipelines 12 to the distribution manifold 13. The pipelines 12 can pass through the first heat exchange means 5 with the formation of one of its branches (see figure 1). In another embodiment of the installation 1 (see FIG. 2), the first heat exchanger 5 is located in the lower part of compartment 3, and the pump 11 picks up the water heated by this heat exchanger and directs it directly to the collector 13 for further distribution over the upper surface of compartment 3.

Bath 2 is divided into a number of compartments by means of partitions 14 having openings 15 at different levels, forming a labyrinth for the water flowing to the far compartment 10, with the help of which water is purified from dirt and sand by precipitation in front of the openings 15.

In compartment 3, a filter grill 16 is fixed, on which the discharged snow falls and which is the first barrier to debris and dirt falling with the snow.

The heat source used in this solution is a fuel heating device, which may include burner (s) (nozzle (s) 17 connected by pipe 18 to a fuel source.

To control the operation of unit 1, various control and measuring equipment (not shown in the drawing) can be installed in its highways, such as flow controllers, temperature sensors, etc., the relationship between the elements of which, taking into account the temperature of the thermal agent, fuel in the source heat and a predetermined temperature in bath 2 and water supplied to the snow ensures reliable and efficient operation of the installation for melting snow and saves heat.

In one preferred embodiment (see FIG. 1), the installation 1 operates as follows. Vehicles dump collected snow into compartment 3 of bath 2, in which water is located. Snow does not fall to the bottom of the compartment, but is located in its upper part. Warm water from collector 13 with a temperature of + 20-40 ° C, which accelerates the process of snow melting, is supplied to the snow from above. The supply of warm water is carried out using a pump 11, which delivers the water taken in the compartment 10 through the first heat exchange device 5, which provides heating of the water to the desired, predetermined temperature. It should be noted that the design of the first heat exchanger 5 provides for sufficiently large dimensions (cross-section) of the channels for the passage of water coming from the pump 11, in order to ensure its uninterrupted flow and to exclude the possibility of clogging of the channels, because water from compartment 10 contains individual contaminants. In this embodiment, the water supplied by the pump 11 is heated due to the presence of a looped line 7 through which the pump 8 drives a heat agent heated in the second heat exchange device 6. The first heat exchange device 5, in which water flows from the compartment 10, is separated from the second heat exchange device 6 using a looped line 7 avoids during an emergency the ingress of contaminants into the latter.

The warm water supplied to the snow is mixed with the water available in the bath 2 and the molten snow and sent to the far compartment 10, from which the water is sent along the melt water discharge line 4, and part of the water is taken by the pump 11 for further cycle. The increase in water level in bath 2 occurs due to the discharged and melted snow, while the discharge of melt water is designed so that the water is almost at the same level, i.e. the discharge rate of water is equal to the increase in the amount of water from melted snow. When passing through the holes 15 of the partitions 14, water leaves most of the dirt and sand in it at the bottom of the compartments, and at the inlet of the pump 11 some kind of device can be provided to prevent the ingress of dirt into it, most of which remains on the grill 16 and before holes 15.

In this utility model, a heat source providing the entire process of heating a thermal agent and maintaining its temperature at the proper level is a device that uses heat from the combustion of fuel, for example, diesel. Fuel is supplied through a pipe 18 under pressure to burners or nozzles 17, in which fuel is burned and combustion products are injected into a heating station (tank) 9. Heat is transferred here, for example, at a temperature of about 90 ° C, from the gas in tank 9 or liquid to the second heat exchanger 6. In the case of paragraph 9, the liquids of the burner 17 are provided with known protective caps. It is possible that the tank in which the burners are installed is separated from the second heat exchange means, and the heat is transferred through piping, through which the products of combustion of fuel flow and which is located on the side of the heat exchange means.

In another embodiment of the installation 1, shown in figure 2, most of its work is performed as described in the first embodiment. The difference is that the first heat exchanger 5 is located in the lower part of compartment 3, and the pipelines 12 from the pump 11 go directly to the manifold 13. In this embodiment, melt water is heated directly in compartment 3 by the first heat exchanger 5, and the pump 11 picks up the already heated water and feeds it through the collector to the snow. However, in the second embodiment, the dirt from the discharged snow can sufficiently get on the heat exchange device 5, which can cause damage and difficulty in cleaning the dirt from the bath.

The use of an autonomous fuel heating device in this utility model makes it possible to operate the installation in various settlements, including those located at a considerable distance from the city centralized heat mains, while all the advantages of the installation with two heat exchangers are preserved. Such an installation is compact and quite easily transported from one destination to another. The operation of the installation in the absence of snow and when cleaning dirt and debris from it is carried out by conventional means known in the art. The preferred embodiments of the installation are disclosed in this description, but it should be understood that, without departing from the essence of the utility model, other modifications can be proposed that are within the scope of the utility model stated in the proposed formula.
