Oil smoke emissions from kitchens in the catering service industry and oil smoke pollution caused by industrial manufacturing (heat treatment, hot forging and other processes) have become social hazards that must be solved.

Traditional mechanical filtration methods, electrostatic purification methods and ordinary wet purification methods have all proven to have serious shortcomings and are not sustainable in practice.

This system combines the advantages of multiple wet purification methods, avoids many defects of ordinary wet purification methods in the oil smoke environment (blocking, difficult to maintain, lack of sustainability, secondary pollution, etc.), and is supplemented by targeted washing media., the oil smoke removal efficiency is expected to reach more than 96%.

This system solves the biggest problem existing in ordinary wet purification methods: secondary pollution. The system comes with a simple, economical wastewater treatment device with good purification effect, so that the soot purification waste liquid can be discharged up to standard after treatment, or can be directly reused, eliminating the secondary pollution chronic diseases common to wet soot purification equipment., further enhancing the market competitiveness of the system and equipment.

Based on long-term research and development and application experience, this system integrates and improves the traditional wet purification method to maximize its strengths and avoid its weaknesses, facilitate its practical popularization and widespread application, and achieve the goal of accelerating the haze reduction process and significantly improving the atmospheric environment.

This system focuses on using efficient and cheap cleaning media while ensuring high purification efficiency to significantly reduce system operating costs.

Application situation or application prospects：This project can be applied to various catering service industries, public kitchens, public flues of large residential buildings, and manufacturing industries (heat treatment, hot forging and other processes) to solve the problem of purifying large and concentrated oil fume and produce obvious economic and social benefits. It is planned to complete the application test in an enterprise in Shanghai (not yet carried out, the plan has been completed).

The system has the following characteristics (innovative) points:

The system is integrated, with small size, streamlined equipment, and high purification efficiency, which is expected to reach 96% or even more.

Washing medium is recycled, with high utilization rate and low cost;

The system comes with a wastewater treatment device with good purification effect, so that the soot purification waste liquid can be discharged up to standard after treatment, or can be directly reused; solving the problem of secondary pollution;

The operation of the purification and dust removal system is mechanically controlled, with good stability, convenient maintenance, simple equipment, low investment, and high cost performance.
