Abstract

The invention belongs to the technical field of dust control, and discloses a centrifugal jet atomization and ultrasonic atomization combined method with a water-saving characteristic, which comprisesthe following steps of: carrying out high-speed rotation and throwing on liquid, and primarily atomizing liquid drops under the action of centrifugal force to obtain fog drops of which the central particle size is less than 20 microns; and enabling the primarily atomized liquid drops to impact the surrounding ultrasonic vibration wall surface, generating vibration with different wavelengths by controlling the vibration frequency of the ultrasonic vibration wall surface, and superposing the vibration with impact capillary waves to promote the atomization of the liquid drops, so as to obtain amicro fog group with the particle size of less than 10 microns. A fog group with the central particle size smaller than 20 microns is obtained through a crushing atomization mechanism under the actionof centrifugal force and transverse air flow, and then a micro fog group with the central particle size smaller than 10 microns is obtained through further crushing by utilizing the atomization mechanism of impacting the ultrasonic vibration wall surface. The atomization efficiency is improved by controlling the incident speed of liquid drops, the wettability and roughness of the solid surface, the viscosity of the liquid drops, the radius of the liquid drops and other parameters, and the purpose of water saving is achieved.

Description

technical field [0001] The invention belongs to the technical field of dust control, and in particular relates to a method for combining centrifugal jet atomization and ultrasonic atomization with water-saving characteristics. Background technique [0002] Engineering tunnels and mining equipment operate in a relatively large concentration of dust, which will aggravate equipment wear, block pipelines, etc., resulting in mechanical accidents. Among them, roadheaders, shearers, conveyors and hydraulic supports have the highest accident rate, reaching 30%, of which 80% are lost due to mechanical wear and tear. [0003] Through the above analysis, the existing problems and defects of the prior art are as follows: the existing dust prevention and control technologies mainly include spray dust reduction, ventilation and dust exhaust, dust capture and purification, and high-pressure water injection. Spray dust suppression generally requires pressurized equipment and nozzles, whi...
