In the field of industrial dust control and environmental protection equipment, the self-excited wet dust collector has become an ideal choice for many companies to handle dusty gases due to its advantages of efficient purification, compact structure, and stable operation. The equipment combines the dual principles of water film dust removal and impact water bath dust removal. It achieves efficient dust removal through its own airflow disturbance without relying on an external high-pressure water source. It is widely used in many industries such as metallurgy, building materials, chemicals, and boiler flue gas treatment.The biggest feature of the self-excited wet dust collector is the "self-excitation" mechanism. It uses the strong vortex and water body oscillation generated when the high-speed airflow enters the washing chamber to make the dust particles quickly collide with the water droplets and be captured, thereby achieving an efficient dust removal effect. This process does not require the additional configuration of a high-pressure water pump or spray system, which greatly reduces energy consumption and equipment complexity, while also reducing maintenance costs and improving the overall reliability of the system.In terms of dust removal efficiency, the self-excited wet dust collector performs particularly well. Due to the multi-stage purification structure, including cyclone separation, water film adsorption and foam washing, it can effectively remove suspended particles with smaller particle size, and has a strong ability to capture fine particles below 5 microns. The dust concentration of the treated exhaust gas is much lower than the national emission standards, meeting the increasingly stringent environmental protection requirements, and is particularly suitable for treating gas environments with high humidity, high temperature or containing sticky dust.In addition, the self-excited wet dust collector has good corrosion resistance and anti-scaling ability. Its internal structure is made of high-quality anti-corrosion materials, such as fiberglass reinforced plastics (FRP) or stainless steel, to ensure that the equipment is not easily corroded by acid and alkali gases during long-term operation. At the same time, the unique water circulation design can prevent the deposition of impurities in the water, reduce the risk of blockage, and keep the equipment in an efficient operating state.The installation and operation of the equipment are also extremely simple. The whole machine has a compact structure and a small footprint. It can be flexibly arranged according to the site conditions and is suitable for various small and medium-sized boilers, furnaces or spraying production lines. During operation, it only needs to regularly add an appropriate amount of clean water to maintain normal operation. It has a high degree of automation and does not require special personnel on duty, which greatly improves the convenience of use.It is worth mentioning that the self-excited wet dust collector also has good adaptability. It can not only be used alone, but also can be used with other dry dust removal equipment to form a composite dust removal system to cope with complex pollution sources under different working conditions. For example, when dealing with sulfur-containing gases, the simultaneous desulfurization function can be achieved by adding neutralizers such as lime to further improve the comprehensive purification capacity.As the country continues to increase its efforts to prevent and control air pollution, the self-excited wet dust collector is gradually becoming the preferred solution for environmental protection in small and medium-sized enterprises and emerging markets with its excellent cost-effectiveness, stable performance and low operation and maintenance costs. It not only helps companies achieve green production goals, but also contributes to improving regional air quality.
