Composite lampblack purification device

Abstract

The invention discloses a composite lampblack purification device which comprises a charged dust removal mechanism, a connecting cover, an electric coagulation dust removal mechanism, a dust collection mechanism and an ultraviolet degradation mechanism which are sequentially mounted and connected in the linear direction. According to the invention, the composite structural design is adopted, so that the lampblack can be efficiently and thoroughly purified; the charged dust removal mechanism enables lampblack particles and peculiar smell molecules to be charged, then particle growth is conducted through the electric coagulation dust removal mechanism to become large-diameter particles, the grown charged particles are then subjected to dust collection through the dust collection mechanism and finally discharged through the ultraviolet degradation mechanism, so purified air is obtained, and good practical and popularization value is achieved.

Description

technical field [0001] The invention belongs to the field of oil fume purification, in particular to a composite oil fume purification device. Background technique [0002] With the rapid development of modern industry and urbanization, people's living standards have been improved to varying degrees, and the requirements for high quality of life are getting higher and higher. However, the surrounding environment where people can survive is deteriorating day by day, especially It is an occasion where people live. In these occasions, although there are fewer large-scale factories, there are generally more restaurants, and the restaurants produce more oily fumes. These oily fumes can easily cause pollution in the surrounding communities, including indoor air. According to the survey, everyone spends at least half of their time in the indoor environment on average, and the elderly, children, pregnant women and patients spend longer indoors and have higher requirements for air qu...

Problems solved by technology

For the oil fume in these catering industries, the current conventional treatment methods mainly include: mechanical method, filtration method, electrostatic adsorption method, ultrasonic atomization method, and ultraviolet lamp method. These methods will have certain effects when dealing with oil fume. However, Each technology has certain defects. For example, the mechanical method mainly uses centrifugal action to shake off the oil fume, but the smoke and odor molecules in the oil fume basically have no treatment effect.

Although the electrostatic adsorption method can adsorb smoke and dust, the dust adsorbed on the electrode plate will hinder the discharge. When the accumulated dust reaches a certain level, the effect of the electrostatic adsorption method will be greatly reduced.

Since the indoor air treatment method is very different from the industrial waste gas treatment method, it is required to be carried out under normal temperature and pressure, so advanced oxidation technology has become a commonly used method, and the more commonly used methods are photocatalytic technology and adsorption filtration method. And plasma method, for photocatalytic technology, under the irradiation of ultraviolet lamp, photocatalyst can decompose volatile harmful gas into harmless small molecular gas, but because the concentration of volatile harmful gas in indoor air is low, using light The removal effect of the catalytic form is not ideal; the adsorption filtration method mainly uses activated carbon and molecular sieve to filter the pollutants to achieve the purpose of purification, but the adsorption materials have a certain adsorption capacity. After the maximum adsorption capacity of the adsorption material, the adsorption material will lose its adsorption function, and it will easily cause secondary pollution to the air.

Most of the current mainstream air purifiers use adsorption filters to purify the air, so customers must frequently replace and clean the filters, which is cumbersome

[0004] The plasma method is to treat air pollutants through plasma discharge. The plasma suitable for indoor air treatment is classified according to the discharge method. There are two main types, one is corona discharge, the other is dielectric barrier discharge, corona discharge It is generally suitable for the treatment of particulate matter and microorganisms. Due to the weak discharge, the treatment effect on volatile organic compounds is average. The current corona discharge generally uses a single positive corona or negative corona, lacking positive and negative corona, that is, lacking solid particles. The process of growth; dielectric barrier discharge is more suitable for the treatment of volatile organic compounds, but it has almost no treatment effect on solid particles. The current dielectric barrier discharge generally uses air as the discharge gas, and the air discharge method plays a role in the treatment of pollutants. The main function is ozone, which has a good effect on removing volatile harmful gases, but when the ozone concentration exceeds a certain standard, it will cause certain damage to the human body, so many plasma air technologies now use as much as possible There may be fewer plasma generating devices that generate ozone, and the reduction in ozone production will definitely weaken the effect of air purification. In addition, this method is still difficult to ensure that the plasma air purifier will work in a closed environment for a long time. Excessive levels of ozone produced
