A spiral atomization jet dust suppression device

Abstract

The invention discloses a screw type atomization-spraying dust precipitating device applicable to atomization of water or water-air and other media with relatively low viscosity. An upper end cover of the device adopts a cylindrical structure, an external thread is arranged at the upper end part, an air inlet is horizontally formed in the middle of the upper end cover and adopts a bolt hole structure, a screw valve is arranged in the center of the upper end cover, and the screw valve and the center of the upper end cover are located on the same axis; a taper hole is formed in the center inside the screw valve and connected with the air inlet, through holes are formed in positions equally spaced from the periphery of the taper hole and are water inlets, a plurality of screw grooves are arranged on the outer edge of the screw valve and have rectangular sections, and the length-width ratio of the rectangles is gradually increased; the upper end cover and an oscillation cavity at the lower end are connected through bolts; the lower end of the oscillation cavity is connected with a connecting piece through threads, the connecting piece adopts a U-shaped groove structure, a bulge is arranged in the middle of the U-shaped groove, and a horn-shaped spray head is arranged in the center of the bulge. The device is simple in structure, easy to control and adjust, good in atomization effect, high in practicability, safe and reliable.

Description

technical field

[0001] The invention relates to a spiral atomization jet dust suppression device, which belongs to the field of atomization dust removal. Background technique

[0002] The improvement of the degree of mechanization has resulted in more and more coal dust generated during the coal mining process. Dust sources mainly come from coal mining face, tunneling face, coal transportation and reloading points, etc. Coal dust not only affects the underground working environment, but also seriously endangers the physical and mental health of employees. Working in a high-concentration coal dust environment for a long time can easily make employees suffer from pneumoconiosis. In addition, when coal dust reaches a certain concentration, it is easy to cause explosion accidents, causing casualties and economic losses.

[0003] The dust removal in the prior art adopts wet dust removal, and the dust reduction effect is good. Among them, spray dust suppression is the most comm...
