Description

The invention relates to techniques for spraying liquids, can be used in the energy, chemical, metallurgical, construction and other industries, for example, for irrigation of various surfaces and dust suppression.

The aim of the invention is to increase the efficiency of the device by increasing the uniformity of spraying and dispersion of the droplets of the irrigating liquid.

Figure 1 shows the proposed device; figure 2 is a cross section aa in figure 1.

The device for spraying liquid contains a horizontally arranged pipe 1 for liquid (water) with holes 2 in communication with the pipe 1 for liquid tank 3 rupture of the jet, which is installed regulator 4 fluid level pipe 5 for air installed parallel to the pipe 1 for liquids and pneumatic sprayers 6 with channels 7 dl

air connected to the pipe 5 for air and channels 8 for sprayed liquid, communicated through tubes 9 to the pipe 1 for liquid through the holes 2 made therein. At the ends of the pipe T for liquid and the pipe 5 for air, plugs 10 are installed. Structurally, pneumatic sprayers mounted on a pipe 5 dl of air along its length.

A device for spraying liquid works as follows.

Liquid through the valve of the float regulator 4 of the liquid level enters the tank 3 of the rupture of the jet and then into the pipe 1. When the set level is reached, the regulator 4 shuts off the supply of the sprayed substance. When compressed air is supplied to the pipe 5, it enters the air channels 7 of the pneumatic guns G The exit from the air channels 7 of the nozzles 6 with high speed, the compressed air creates in the place of its expiration a zone of reduced pressure, where from the pipe 1 through the tubes 9 share

the irrigation liquid is sucked in. As a result of the collision of the jets of compressed air and the sprayed material in each pneumatic sprayer 6, the spraying process starts, and along the entire length of the pipe b a directional torch of finely dispersed particles of the sprayed liquid (fog) is formed, which is directed to the irrigated surface. When the supply of compressed air to the pipe 5 is stopped, the suction of liquid from is also stopped. pipes 1.

For the device to work, it is necessary that the liquid mirror in the jet break tank 3 be higher than the pipe 1, while the most economical and reliable operation of the liquid spray device is provided at the level of the sprayed substance in the jet break tank 3 in one plane 6 with the axis of the air pipe 5.

The required dispersion of the sprayed liquid is obtained by appropriate selection of the diameter of the air channel of the pneumatic atomizer and by adjusting the pressure of the compressed air.

The number of pneumatic sprayers located on the air pipe and the distance between them depends on the required density of the sprayed substance and the distance to the irrigated surface.

Providing the device for spraying liquid with an air pipe with pneumatic atomizers installed on it allows to obtain an expanded torch of finely dispersed particles of the sprayed substance and its uniform application on the irrigated surfaces, which increases the efficiency of the device.

it maintains a constant flow rate of the sprayed substance and the independence of this flow rate from the liquid pressure in the supply pipe,. the reliability of the device is improved. The reliability of the device is also enhanced by the fact that the tank for breaking the jets additionally acts as a filter precipitator. Foreign solids entering the tank together with the liquid settle to the bottom of the tank, thereby eliminating the possibility of clogging of the pneumatic atomizer channels for water with these inclusions. ; ;:

Claims (1)

The device will be effective in dust suppression, since finely dispersed water droplets come out of pneumatic sprayers with a sufficiently high efficiency, which increases the likelihood of wetting and trapping small particles of dust. The presence of an extended plume of water particles during operation of the device of the invention makes it possible to effectively use it to irrigate the surface of a dusting material transported, for example, by conveyors. . -... ..
