With the rapid development of Chinese economy, the environmental pollution is becoming increasingly serious. In most parts of China, human pollution of air, soil and water have been far beyond the capacity of nature. In recent years, frequent smog, water pollution and soil pollution has become increasingly serious. Painting is a high pollution, high energy-consuming industries. In the paint production process, it will produce a lot of waste gas, waste water and solid waste. In order to maintain constant temperature and humidity conditions required for painting, also we need to consume a lot of energy and fossil fuels.

Paint mist separation technology is mainly divided into dry and wet two. Conventional dry paint system is mainly used in the form of mist filter felt trapped mist separation, is purely a single layer filtering technology, can easily lead to local saturation of the filter material clogging of mist capture ability is very accommodating limited, need frequent replacement mist filter felt. Frequent replacement filter felt the need to stop production, not only increases the filter material and labor consumption, but also take a lot of production time, high production costs, solid waste and more. Secondly, the technology of mist separation effect is very limited, air separation still contains a certain amount of mist, not only can not meet the quality requirements for the use of air circulation, but also there is a big fire safety hazards. Traditional dry technology can only be used in small batches, batch spraying operations, it is difficult to use in large quantities of continuous industrial production.

Wet paint mist separation technology mainly Venturi mist separation and water separation technology rotating the mist, wet mist separation technology, while enabling continuous separation of the mist, and can meet the needs of high-volume continuous operation, but this technique will produce a lot of waste gas, waste water and waste, we consume a lot of fresh air temperature and humidity, high energy consumption. Part of wet mist separation technology production lines Although the use of recirculated air technology, reduces the amount of fresh air consumption and exhaust gas, but after a wet mist separation air is very humid, low temperature, dehumidification and heating can be recycled , dehumidification and heating energy consumption is also high, this circulating air technology also consumes a lot of energy. In addition, the circulating pump also need to consume a lot of electricity and chemicals is not a small expenditure, high paint residue using a wet mist separation techniques mist generated by the moisture content of the total paint large slag, paint residue the treatment costs are high.

In recent years, some foreign companies have developed a number of dry separation techniques, such as through the use of auxiliary materials to reduce the viscosity of spray material, and then by separating solids and gas filtration technology, the technology necessary to add a large amount of auxiliary materials, greatly increased solid waste the amount thereof. The company also uses electrostatic paint mist separation technology, but this system was vulnerable to overspray adhesion and difficult to remove the problem. In addition, these devices are complex and expensive, currently only in some high-end production lines are applied, it is difficult to be widely used.

The current status of the spray painting industry is: Traditional dry spray booth no way to meet the needs of high-volume continuous operation; high investment costs are generally traditional wet paint mist separation technology energy consumption, heavy pollution; lime and electrostatic spray booth Although the low energy consumption, but expensive, also Some could not solve the problems that comes with the system itself. In the global energy conservation and emission reduction of the environment, the spraying industry is in urgent need of a low investment, low energy consumption, pollution of small spraying equipment.

Jiaxing Qijing Painting Technology Co.,Ltd  in absorbing foreign advanced technology, after several years of research and development, a series of independent research and development to meet the now dry spray booth coating industry needs. Its performance indicators is in the leading level in the world, has received a number of national patents.
