Description

High efficiency dry dust removal system

The present invention relates to the field of dust removal technology, in particular to a high-efficiency dry dust removal system, which uses a gas supply source, a gas flow controller and an ion wind generator, as well as a dust collection and removal system, and can effectively remove dust on the mold stamping area, improve the quality of product printing or marking, and reduce pollution to the environment.

In the process of industrial production, dust is an inevitable product, especially in the fields of printing, electronics, plastics, etc., where the impact of dust on product quality and production environment is particularly significant. In order to ensure product quality and working environment hygiene, it is necessary to effectively remove dust from the production site. Traditional dust removal methods mainly include wet and dry methods. The main principle of wet removal method is to use water or other wet media to adsorb dust, while dry methods mainly include electrostatic adsorption and mechanical filtration.

Wet dust removal methods have certain defects, such as the need to consume a large amount of water resources, produce wastewater pollution, and may cause corrosion of some equipment. In comparison, dry dust removal technology is more environmentally friendly and economical. However, existing dry dust removal technology also has some problems, such as low efficiency, complex operation, and high equipment maintenance costs.

In the prior art, a common dry dust removal method is to use the principle of electrostatic adsorption. This method generates electrostatic attraction on the dust surface to adsorb the dust onto the dust collector. However, this method has the problem of low efficiency, because the electrostatic adsorption force is affected by many factors such as dust particle size and dust charge properties, and the adsorption effect of different types of dust may vary greatly. In addition, the electrostatic adsorption method requires regular cleaning of the dust collector to maintain the dust removal effect, which increases maintenance costs and workload.

Regarding the literature on dust cleaning, there are several patents as follows:

Taiwan I311646 discloses a dry purification system using laser light, which is about a dry purification system using laser light to remove pollutants from a cleaning object, and aims to provide a dry purification system that uses light energy - laser light to effectively remove pollutants from a cleaning object, especially to remove pollutants on the surface of the contact part of a semiconductor test seat.

The air source is installed on the flow guide element and connected to the annular flow channel. The air source is used to provide an air flow, and the air flow is guided through the annular flow channel.
