Description

The invention relates to environmental protection means, namely dust suppression devices, can be used for dust removal, irrigation of areal sources of dust emission, as well as for dust removal from a source of dusty air, where it is necessary to use dust suppression systems with the possibility of processing large areas in automatic mode.

A known method of dust suppression on the beach areas of the tailings and a device for its implementation (RF patent No. 2272147, publ. March 20, 2006), comprising a vehicle and mounted on it a container for a reagent, pump, hydraulic monitor, which is mounted with the possibility of rotation in horizontal and vertical planes, characterized in that the vehicle is a watercraft, for example a pontoon, on the deck of which there is a pump, a hydraulic monitor, a unit with a working body for laying a channel in the coastal strip and autonomous power station, to which the drives of all mechanisms are connected, while the working body is installed below the draft line of the craft with the possibility of rotation in planes, and the tank for the binder reagent is equipped with a dispenser.

The disadvantage is the use of a craft and a node with a working body for laying a channel in the coastal strip to move the device, which will not allow the device to be used quickly and automate the process of dust suppression.

A device for dust and gas suppression (RF patent No. 2096625, publ. 11/20/1997), comprising a jet engine, a mixing chamber with a fluid supply manifold and an accelerating nozzle, characterized in that the jet engine is connected to the mixing chamber by a diffuser, and the accelerating nozzle is located on the output of the mixing chamber, characterized in that the accelerating nozzle is made with parameters for a two-phase gas-liquid flow, while the axis of the nozzle nozzles are located to the axis of the mixing chamber at angles of proportional It is the distance from the nozzles to the camera axis.

The disadvantages of the device are the use of a jet engine, the use of which is accompanied by significant costs for operation and maintenance, the inability to quickly move the device due to the need for its stable fixation, the need to use several devices in a stationary location.

A device for generating precipitation is known (RF patent No. 10780, published on 08.16.1999), including an aircraft with a rotor and a drive, a water supply unit, characterized in that the drive is made hydraulic, and the water supply unit contains a pump located at a distance from the aircraft and connected by a pipeline to the drive, while the hydraulic drive contains serially connected through the hollow axis of the screw and the blades of the hydraulic motor and nozzles.

The disadvantage of this device is the use of a hydraulic drive for movement, the range of movement is limited by the critical length of the high pressure sleeve used in the water supply unit.

A well-known gas-water quenching vehicle AGVT (a brief description of the device is given in the article "Energy-efficient vortex equipment" / V.P. Kashcheev, E.O. Voronov, O.V. Kashcheeva, V.A. Gashenko, N.N. Ulasyuk, V. V. Sorokin // News of higher educational institutions and energy associations of the CIS. - Energy: international scientific and technical journal. - 2013. - No. 1. - p. 78-87), adopted as a prototype, which is mounted on a truck chassis aerosol fogger gun with guidance device, compressor and pump mill ii, a water tank, an electric current generator, a control unit and control.

The disadvantages of the device are the impossibility of its use for operational dust suppression in accordance with the current production monitoring data due to the inability to operate the device in motion in automatic mode, the relatively small mass of water transported in the tank, as a result, the need for frequent replenishment of the tank.

The technical result of the invention is a complex that automatically automatically promptly hydrates a dusty surface, or hydrates the streams of dusty air coming from an array in areas characterized by the largest amount of dust.

The technical result is achieved by the fact that the dust suppression complex of areal sources, including a vehicle, on which an aerosol canister with a guidance device, compressor and pumping stations, a water tank, an electric current generator, a control and monitoring unit are installed, according to the invention, the vehicle is used a railway platform moving along a rail track along a dusting massif, on a rail track opposite the boundaries of the section of sections of the massif There are passive RF tags, and a tag reader and a wireless data transmission device are installed on the platform for receiving and processing industrial monitoring data and remote automatic control.

The dust suppression complex of area sources is illustrated by the following figure:

FIG. 1 - Dust suppression complex of area sources, where

1 - passive RF tags;

2 - water tank;

3 - railway platform;

4 - drive engine;

5 - electric current generator;

6 - electronic control control unit;

7 - a device for wireless data transmission;

8 - pumping station;

9 - compressor station;

10 - aerosol fogger gun;

11 - aerosol gun guidance device;

12 is a tag reader.

The dust suppression complex of areal sources (Fig. 1) is a railway platform 3 used to move the complex along the array, an aerosol fogger 10 is mounted at the end of the platform, mounted on the guidance device 11, a pump station 8, a compressor station 9, water a tank 2, providing the operation of an aerosol fogger gun, a drive motor for moving the railway platform 4 and an electronic control control unit 6, a wireless device water data transmission 7, as well as an electric current generator 5 for powering them. Passive radio-frequency tags 1 are mounted on the rail opposite the boundaries of the section of the sections of the array, and a device for reading them 12 is installed on the platform at the level of the location of the tags.

The complex works as follows. The railway platform 3 by means of a drive motor 4 moves along a rail track located along the dusting massif. Using the wireless data transmission device 7, production monitoring data is received (temperature and humidity, wind speed and direction, rainfall, array replenishment mode) obtained in real time, according to which electronic replenishment and control unit 6 determines the areas of replenishment of the array with the greatest dust emission, sets the order and the necessary intensity of their processing. Further, by reading the passive RF tags 1 by the device 12, the complex automatically moves to the tag corresponding to the boundary of the first, according to the established sequence, section of the array. In accordance with the wind direction, the direction of the aerosol fogger gun 10 is selected, which is set by the guidance device 11. Based on the calculated intensity of the plot processing and the direction of the aerosol gun, the flow rate of the gun and the speed of the complex during processing are selected. After that, automatic processing is performed when the complex moves to a radio frequency tag located on the opposite boundary of the site. Then the cannon’s work stops, and the complex moves to the next, according to the turn, section of the array and so on. A pump station 8 is used to supply water from a water tank 2 to nozzles in an aerosol cannon, a compressor station 9 produces compressed air to spray water in the nozzles, an electric current generator 5 is used to power the electrical equipment of the complex.

Thus, the complex allows processing sections of the array characterized by the largest amount of dust emission, and the use of the rail track and passive RF tags to coordinate the movement of the complex allows you to fully automate the dust suppression process, that is, to exclude operator’s participation in controlling the movement of the complex, as well as setting the direction of the aerosol gun fogger and adjusting the flow rate of water during its operation. The use of the rail, also, will increase the mass of water transported in the complex, reduce the frequency of replenishment of the tank. The use of a dust suppression complex for areal sources will fully automate the dust suppression process, perform dust removal promptly, as well as increase the mass of transported water supply for an aerosol gun, that is, reduce the frequency of replenishment of the tank compared to devices based on wheeled vehicles.
