Description

The utility model relates to the field of meteorology and can be used to artificially disperse warm fog on the road.

US patent No. 4125223, E01H 13/00, 1977 presents a device for dispersing fog containing means for heating air along a runway. Air from the engines, heated by the burners, enters pipelines that direct it at various angles relative to the surface of the runway. The disadvantage of such a device is that when natural gas is burned to heat the air, a large amount of water vapor is formed, which reduces the dissipation efficiency.

A device for dispersing fog with dry cold air is known (US patent No. 3598313, E01H 13/00, 1971), which contains an air intake, a turbine with a drive, a drying unit in the form of a chamber with a refrigeration unit and an outlet pipe. Air with fog droplets is sucked into the chamber of the drying unit using a turbine, where it is dehydrated by cooling, and then through the outlet pipe it is pushed into the controlled space area. Dried air displaces fog from the controlled area. The disadvantage of such a device is the presence of a bulky refrigeration unit, which does not allow the installation to be mobile; in addition, it has low efficiency, since when the fog is cooled, the number of droplets in it first decreases and then stabilizes and the emitted air is not sufficiently dried.

Invention patent No. 2160001 Ru presents a mist dispersion device in which mist is pumped into a drying unit consisting of a condensation chamber installed at the compressor inlet. Due to adiabatic expansion, the air is dried, after which it is compressed in a compressor and released into the atmosphere.

Patent for invention No. 2164062 Ru presents a device for dispersing fog, the principle of which is similar to the device for patent for invention No. 2160001 Ru, and in which the exhaust air is additionally heated.

There is a known method of dispersing fog (patent for invention No. 2767611 Ru), which is based on cleaning the fog from the droplets it contains by moving it with excess pressure through a porous structure with open pores, which, in the process of moving the fog through it, is moved in the plane of the intersecting fog flow line.

The technical solution for invention patent No. 2781216 RU implements the method described in patent No. 2164062 Ru. In this technical solution, in a fairly simple way, the process of forming an air flow cleared of fog droplets is implemented, which makes it possible to displace fog from the controlled area. However, unfortunately, the range of action of the formed jet of air purified from droplets of fog is insignificant, and can be about 10 calibers of the device that forms it. And to dispel fog on a section of the road, it is necessary to install these devices along the entire controlled section of the road. Considering that fog on the road does not occur very often, not only the installation, but also the maintenance of this inoperative expensive equipment mounted along the road requires significant costs.

The closest technical solution to the proposed one is the device described in the method for dispersing fog in the state of Utah. This technical solution uses liquid carbon dioxide to disperse fog and improve visibility on sections of interstate highways. Fog dispersal equipment, consisting of commercially available products, is installed on approximately 70 maintenance vehicles. Each truck is equipped with a compressed gas cylinder, manual valve assembly, mounting brackets, copper pipe and dispensing nozzle. Each cylinder contains liquid carbon dioxide at a pressure of 2,000 pounds per square inch. (https://ops.fhwa.dot.gov/weather/Publications/Case%20Studies/22.pdf.). When fog is needed, vehicles drive through supercooled fog and use the truck's tailpipe to spray liquid carbon dioxide along the road. Carbon dioxide quickly evaporates, removing heat from water droplets in the fog. The droplets form ice crystals and precipitate as fine snow or ice. This fog dispersal method improves mobility and road safety, increasing the visibility distance behind the maintenance vehicle from 10 meters to 500 meters in less than 30 minutes. The procedure remains effective for 30 minutes to 4 hours, depending on air temperature and wind speed. Improved visibility has significantly reduced the number of vehicle collisions.

At the same time, this fog dispersal system can solve the problem of dispersing only supercooled fogs. This system is not suitable for dispersing warm fogs.

The purpose of the proposed utility model is to dispel warm fogs on the road without increasing costs to achieve this goal.

To achieve the stated goal, a known device containing a vehicle is equipped with a system mounted on it for forming air flows cleared of fog droplets, made in the form of a fan installed in the air duct with a drive, on the axis of which a filter element is fixed, made in the form of a rotating porous one with open pores. disk, while in the air channel, in the area surrounding the porous disk, a shell is inserted, in the lower part of which there is a drainage hole, and in the upper part of the device there is an air intake connected to the air channel.

The technical result in the proposed technical solution is achieved due to the fact that the system for generating air flows cleared of fog droplets is mounted on a vehicle, which, moving along the road, blows fog off the road. The system for forming air flows cleared of fog droplets is made in the form of a porous rotating disk with open pores, while in the air channel, in the area surrounding the porous disk, a shell is inserted, in the lower part of which there is a drainage hole, and in the upper part of the device there is an air intake, connected to the air channel.

This design provides free through passage of air flow through the open pores of the rotating disk. The droplets collide with the pore structure of the rotating disk, stick to them and are separated from the air flow. As droplets accumulate on the pore design elements, they become larger and, under the influence of centrifugal forces, are thrown to the periphery. The air flow, cleared of fog droplets, is carried out and displaces the fog with the pressure of its jet from the section of the road on which the vehicle is currently located. As the vehicle with the system mounted on it for generating air flows cleared of fog droplets moves forward, the road is cleared of fog. The number of proposed fog dispersal devices for servicing the controlled section of the road is determined based on specific meteorological conditions and the characteristics of the systems installed on the vehicle for generating air flows cleared of fog droplets. In fig. Figure 1 shows a schematic diagram of a fog dispersion device (side view). In fig. 2 shows its front view.

The proposed fog dispersal device includes a truck 1 equipped with a power supply system (not shown in the graphics). The power supply system can be made from autonomous power sources available on the market (see, for example, https://www.vseinstrumenti.ru/category/istochniki-avtonomnogo-pitaniya-170367/) and installed in the back of a truck, in a space free from systems installed in it for the formation of fog-free air flows. The system for forming air flows cleared of fog droplets can be made, for example, according to a design scheme, a detailed description of which is presented in patent for invention No. 2781216 Ru. The system for forming air flows cleared of fog droplets includes a fan installed in the air channel 2 with a drive 3, on the axis of which a filter element 4 is fixed, made in the form of a porous rotating disk with open pores. In the air channel 2, in the area surrounding the porous rotating disk 4 with open pores, a shell 5 is inserted. The shell 5 is made in length no less than the thickness of the disk 4, and its internal diameter exceeds the internal diameter of the air duct 2 by at least 5 mm. In the lower part of the shell 5 there is a drainage hole 6. For air intake, an air intake 7 is made in the upper part of the device, connected to the air channel 2. To prevent any foreign objects from entering the air channel 2, the air intake 7 can be covered with an air-permeable mesh.

To generate a larger volume of air purified from fog droplets, several systems for generating air flows purified from fog droplets can be installed on the truck, forming jets of purified air. For example, as shown in FIG. 1 and fig. 2, two jets in the direction of movement of the vehicle, one of which is directed forward (W1), the other backward (W2), and air jets to the side (W3) from the direction of movement, to the right, when organizing right-hand traffic of vehicles on a controlled section of the road. Air intake into the system for forming air flows cleared of fog droplets is provided from above (in Fig. 1 and 2 indicated by arrow W4).

The proposed device works as follows. When fog occurs, a truck equipped with a system for generating air flows cleared of fog droplets enters the road and moves in the far left lane (in the case of right-hand traffic, respectively, in the far right lane). With the help of a fan 3, air containing droplets of fog is taken from the space above the truck, and through the air channel is directed onto a porous, open-pore rotating disk 4. Droplets of fog collide with the structural elements of the pores of the rotating disk 4, stick to them and are separated from the air flow . The air flow cleared of fog droplets (in graphic materials designated W1, W2, W3) is carried out and displaces the fog with the pressure of its jet from the section of the road on which the vehicle is currently located. Drops of fog deposited on the structural elements of the pores become larger as they pass through the porous surface of the rotating disk 4. Under the influence of centrifugal forces, drops of fog are thrown towards the walls of the shell 5. Under the influence of gravity, the drops flow down to the drainage hole 6 and are discharged outside. The air flow, cleared of fog droplets, is carried out and displaces the fog with the pressure of its jet from the section of the road on which the vehicle is currently located. As the vehicle with the system mounted on it for generating air flows cleared of fog droplets moves forward, the road is cleared of fog. Thus, the proposed technical solution allows us to solve the problem of dispersing warm fogs on the road without increasing costs to achieve the goal.

In the absence of fog, a truck with a system for generating air flows cleared of fog droplets can be stored in a garage. If necessary, the system for generating air flows cleared of fog droplets can be made in the form of a separate module (container), easily mounted on any vehicle, which will significantly reduce the cost of the equipment. Thus, the proposed technical means allows us to solve the problem of dispersing warm fog on the road, without installing special equipment on it, which reduces the costs of both installing the equipment and its operation, which allows us to achieve our goal.
