A dual-band composite sound wave fog suppression method

Abstract

The invention belongs to the technical field of harmful droplet emission suppression or sound wave application, and specifically relates to a dual-band compound sound wave fog suppression method, which is characterized in that it includes at least a low-frequency sound wave source and an ultrasonic wave source, and the low-frequency sound wave source and the ultrasonic wave source are respectively controlled by The control unit sends low-frequency sound waves and ultrasonic waves to the droplet tank, and the low-frequency sound wave source forms a low-frequency sound field to realize the coalescence of small-sized droplets. It uses the combination of low-frequency sound wave coalescing effect and ultrasonic mechanical effect to suppress the emission of harmful droplets on the surface of the process production tank.

Description

technical field [0001] The invention belongs to the technical field of harmful droplet emission suppression or sound wave application, in particular to a dual-band compound sound wave fog suppression method. Background technique [0002] In the interior of industrial buildings, many production processes will produce a variety of and a large number of harmful droplets. The common types of droplets are acid mist, alkali mist, oil mist, water mist, etc. These droplets, if released into the building interior environment, can cause serious harm to workers, production processes, equipment and building envelopes. [0003] At present, the control methods for harmful droplets generated in the production process mainly include physical control methods (CN208758310U, CN210356413U, CN209371439U) and chemical inhibition methods (CN103628077B, CN104662099A, CN103628077A). Physical means such as ventilation are used to control droplets. Although it is possible to eliminate harmful droplet...

AI Technical Summary

Problems solved by technology

Use ventilation and other physical means to control droplets, although it can eliminate harmful droplets in the building and reduce the concentration of harmful droplets in the indoor environment, but due to the limitations of technological conditions, the size and layout of exhaust equipment are often subject to greater restrictions , and the droplet particle size distribution is wide (from submicron to hundreds of microns), and the movement characteristics are significantly different, which leads to poor control effect of the ventilation system, and subsequent purification equipment is required to purify the droplets, resulting in secondary energy When using the chemical fog suppression method, adding chemical substances such as surfactants to the droplet distribution tank will increase the pollutant components in the waste liquid and cause chemical secondary pollution
