Description

Wet micron particle capture air purification device

technical field

The utility model relates to an air purification device, in particular to an air purification device for trapping micron-sized particles in a closed space.

Background technique

With the development of industry, dense urban population, and the rapid growth of coal and petroleum fuels, the quality of the atmosphere is deteriorating day by day, and air pollution has become one of the main factors that endanger the world's environment and human health. In recent years, particulate pollutants in the atmosphere are the main cause of smog, which has posed a serious threat to human health, ecological environment, and the harmonious development of economy and society, and has the potential to spread to many cities on a large scale Among them, micron-sized particles are the most harmful category.

Micron-sized particles refer to suspended particles in the air whose diameter reaches the micron level, also known as inhalable particles. Inhalable particulate matter can become the carrier of many toxic and harmful substances in the air; after being inhaled by the human body, it will accumulate in the respiratory system, causing heart disease, lung disease, respiratory disease, reducing cardiopulmonary function, etc., and affecting people's respiratory system, nervous system, etc. It will cause serious harm and have carcinogenic, mutagenic and disabling effects. In addition, in production sites such as precision instruments, electronics, and fine chemicals, particulate pollutants will reduce the accuracy and service life of the instruments; they can also cause internal circuit failures of the instruments, and in severe cases, production accidents.

At present, the purification technology to solve indoor air pollution can be divided into mechanical method, physical method and chemical method.

1. Mechanical methods include filtration technology, activated carbon adsorption technology, etc. At present, the most used method is filtration technology, which has inherent deficiencies. All the purification work is done by the filter screen. It is more efficient in the early stage of use, but with the prolongation of use time, the resistance of the filter screen gradually increases, resulting in energy loss. Consumption, noise and other indicators increase, the replacement cycle of the filter screen is short, and the price is expensive; activated carbon adsorption technology is divided into physical adsorption and chemical adsorption, both of which have certain saturation problems, and the adsorbed pollutants may be released, causing secondary pollution. pollute.

2. Physical methods include electrostatic dust collection technology, negative ion technology, low-temperature asymmetric plasma technology, etc. The active ions produced by the above method are unstable and easy to generate ozone, which will cause certain harm to the human body, so it cannot work for a long time. Moreover, electrostatic dust collection and negative ion technology cannot remove harmful gases such as formaldehyde and benzene, and the efficiency of dust removal and sterilization is low; low-temperature asymmetric plasma technology cannot remove micron-sized particles in the air well.

3. The chemical method mainly refers to the photocatalytic purification technology. The disadvantage is that it cannot solve the suspended particles or micron-sized particles in the indoor air; at the same time, the micropores of the catalyst are easily blocked by dust and particles, which will cause the catalyst to be deactivated, the concentration will decrease, and the degradation rate will also decrease.

Most of the air purifiers of mainstream brands in the market today are of the filter type, and the filters are of different forms, but the prices are relatively expensive. The cycle is less than 6 months, the replacement is more frequent, and the cost performance is low. Many purifiers can efficiently purify the air within a certain period of time, but after long-term work, due to the influence of particulate matter in the air, the purification efficiency of the filter screen is significantly reduced, and the purification effect of the purifier is greatly reduced.
