Through the introduction of air filters in the previous article, I believe everyone has the most basic understanding of air filters. Next, let us talk about it.chemical filterThe performance indicators, in order to facilitate everyone in the understanding of the air filter at the same time, the chemical filter has a deeper understanding.
The first is the filtration accuracy of the chemical filter, which refers to the maximum diameter of the impurity particles allowed to pass through. The most important thing that affects the filtration accuracy of the chemical filter is the internal filter element. The operator can select different types of filter elements according to the needs of the original elements to achieve the filtration accuracy we need. Followedchemical filterRefers to the pressure relationship curve between the air flow and the two ends of the filter that can pass through the chemical filter under a certain pressure. In actual use, it is best to control the pressure loss less than 0.03 MPA. The ratio between the separated water and the water contained in the air at the air inlet is called the water separation efficiency. The factory can make the filter have different filtration efficiency according to different concentration doses. The dust concentration divided by the mass concentration means the weight calculation efficiency, and the dust concentration means the counting efficiency by counting concentration. Solid with sodium chloride. As a source of dust, the concentration of sodium chloride particles can be measured by a photoelectric flame photometer.
As a consumer, how should we choose a suitable chemical filter? After correctly measuring the dust content and particle characteristics in the outdoor air, we can choose the desired product according to this data. Including the filtration efficiency, the amount of resistance penetration, the wind speed when filtering, and the amount of air that can be handled, etc., when economic conditions permit, some high-efficiency and easy-to-install filters should be selected as much as possible. Finally, chemical filters are selected according to the analysis of the nature of the cold dust gas, because some filters are used at high temperatures. It will affect its working effect, so choose some high temperature resistant chemical filters, otherwise it will have a serious impact on the air filtering effect. Of course, if economic conditions do not permit, we should give priority to products that are more suitable for us on the basis of a low price.
The explanation on the performance characteristics of chemical filters and how to choose and buy them is here today, hoping to be helpful to everyone when buying products.
