Abstract

The utility model provides an air water atomizer, has one end to seal the trachea that the other end has the air inlet, and the intraductal location even has axis and tracheal axis at the both ends confined water pipe on the collinear, even has the bracket between trachea and the water pipe, and the middle section of water pipe has the radial water inlet that passes tracheal, and the equipartition has the gas pocket on the normal line of trachea pipe wall downside, and the equipartition has the water hole on the normal line of water pipe wall upside. The utility model discloses install the ceiling in the colliery in the pit return air tunnel fixedly, let the gas pocket down, the air inlet passes through the air valve and links to each other with the compressed air supply pipe that supplies, and the water inlet passes through the water valve and links to each other with the delivery pipe. When the dust-removing device is used, water enters the water pipe and is sprayed out of the water holes, water is primarily atomized, compressed air enters the air pipe and is sprayed out of the air holes, entrained water mist is sprayed out of the air holes, the water mist is further refined, and plane water mist is sprayed out of the lower side of the air pipe, so that the dust-removing device is effectively used for dust removal in an air return roadway under a coal mine.

Description

Air water spraying device

Technical Field

The utility model relates to an air water atomizer that colliery return air tunnel dust removal in pit used.

Background

The dust in the underground return air roadway of the coal mine is more, and the dust can be removed by a spraying method in the return air roadway in order to remove the dust. Spraying requires the use of a spraying device.

In the prior art, the spraying device is an atomizer. When the atomizing nozzle is used, the atomizing nozzle is connected to the high-pressure water pipe, and high-pressure water rushes out of the nozzle to form water mist. The water mist sprayed by the spraying device is conical surface water mist sprayed by water pressure from one point, dust can not be effectively removed from an underground return air roadway of a coal mine, water drops in the water mist sprayed by the spraying device are large, the water atomization effect is poor, the dust removal effect is poor, the water consumption is large, and roads in the return air roadway can be muddy. The spraying device is not suitable for being used in an underground return air roadway of a coal mine.

Disclosure of Invention

The utility model aims at overcoming the above-mentioned not enough, provide one kind can spun plane water smoke, water atomization effect better, be suitable for the colliery air water atomizer that uses in the air return tunnel in the pit.

The utility model is realized by the following method.

The air-water spraying device is provided with an air pipe with one end closed and the other end provided with an air inlet, a water pipe with two ends closed and an axis in the same straight line with the axis of the air pipe is positioned and connected in the air pipe, a bracket is connected between the air pipe and the water pipe, a radial water inlet penetrating through the air pipe is arranged in the middle section of the water pipe, air holes are uniformly distributed on a normal line of the lower side of the wall of the air pipe, and water holes are uniformly distributed on a normal line of the upper side of the wall of the water pipe.

During the installation, the utility model discloses the ceiling in the colliery air return tunnel is installed fixedly, lets the gas pocket down, and the air inlet passes through the air valve and links to each other with supplying compressed air pipe, and the water inlet passes through the water valve and links to each other with the delivery pipe.

During the use, open air valve and water valve, water gets into in the water hole blowout annular gap between trachea and the water pipe behind the water pipe, preliminary atomizing water, generate water smoke, compressed air gets into and spouts from the gas pocket behind the trachea, when compressed air from the gas pocket blowout, smuggleing the water smoke in the annular gap between trachea and the water pipe from the gas pocket blowout secretly, compressed air can further refine the water smoke droplet when spouting from the gas pocket to the water smoke, it is better to further refine the messenger water atomization effect to the water smoke droplet, the water smoke that further refines spouts plane water smoke downwards from the gas pocket of the equipartition on the trachea downside normal, be used for the dust elimination in the return air tunnel under the colliery effectively.

The utility model discloses can spun plane water smoke, water atomization effect is better, is suitable for the colliery dust elimination in the air return tunnel in the pit to use

The present invention will be further described with reference to the accompanying drawings.
