With increasingly stringent environmental protection standards, finding efficient and economical methods for waste gas and wastewater treatment has become an important issue facing many companies. As an advanced environmental protection equipment, the self-excited wet dust collector has demonstrated its unique advantages in the fields of die-casting waste gas treatment and hardware wastewater treatment. It can not only effectively remove particulate matter and harmful gases in the air, but also purify industrial wastewater to a certain extent, providing strong support for enterprises to achieve green development.The working principle of the self-excited wet dust collector is based on the interaction between droplets and dust particles. When the airflow containing pollutants enters the equipment, it passes through a water curtain or atomization zone formed by a series of nozzles. In this process, tiny droplets are fully in contact with dust or other pollutants, and these pollutants are captured by mechanisms such as inertial collision, diffusion and sedimentation. Subsequently, the treated clean air is discharged, and the liquid containing pollutants is collected for further treatment or recycling. This design makes the self-excited wet dust collector particularly suitable for treating waste gas containing fine particles and a certain concentration of acid and alkali substances, such as waste gas generated during die casting.For the hardware industry, waste gas and wastewater in the production process often contain heavy metal ions, oil and other chemicals, which pose a serious threat to the environment. Self-excited wet dust collector can effectively remove particulate matter in waste gas and precipitate suspended solids in wastewater through efficient physical separation technology. In addition, some improved self-excited wet dust collectors are also equipped with chemical reaction units, which can neutralize pH or precipitate heavy metal ions by adding appropriate chemical agents, thereby improving the effect of wastewater treatment.From the perspective of economic benefits, self-excited wet dust collector has significant cost advantages. First, compared with traditional dry dust removal systems, wet systems do not require complex filter materials, reducing the cost of replacing filter materials. Secondly, since it mainly relies on water as a medium during its operation, the operating cost is relatively low. More importantly, some models of self-excited wet dust collector support water resource recycling, which not only saves water costs, but also reduces the pressure of sewage treatment. This is especially important for companies with tight water resources.However, to fully utilize the role of self-excited wet dust collector, several key factors need to be taken into account. The first is the design and selection of equipment. Different types of waste gas and wastewater require different design solutions to ensure the best treatment effect. The second is the optimization of operating parameters, including air intake speed, water volume control, pH adjustment, etc., which are key variables affecting treatment efficiency. Finally, daily maintenance, regular inspection of nozzle status, cleaning of scale, and monitoring of water quality changes are all essential, which help to extend the service life of the equipment and maintain stable treatment performance.In summary, self-excited wet dust collector has shown broad application prospects in the treatment of waste gas and wastewater in the hardware industry with its high efficiency, economy and environmental protection. Faced with increasingly stringent environmental protection requirements, enterprises should actively explore and apply such advanced technologies to contribute to the realization of sustainable development goals. In the future, with the continuous advancement of technological innovation, it is believed that self-excited wet dust collector will play a greater role in more fields and help all walks of life move towards a greener and healthier tomorrow.
