What is the difference between pure high pressure oil fume purifier and high and low pressure oil fume purifier?

In the field of lampblack treatment, pure high voltage electrostatic lampblack purifier and high and low voltage electrostatic lampblack purifier are the two most widely used products. In the current product line of our company, ESM and ESM-S are high and low voltage electrostatic type, while PSH and PSM-S are pure high voltage electrostatic type. The applicable objects of the two products overlap somewhat, but they do not seem to be exactly the same. Many people are confused. This article simply answers this question.

Let's first introduce the core difference between the two products - the structure of the electrostatic module.

The electrostatic module of the high and low voltage electrostatic fume purifier is divided into a high voltage electric field area and a low voltage adsorption area.

The electrostatic module of the pure high-voltage electrostatic fume purifier only has a high-voltage area. If you distinguish it with the naked eye, you can notice that the distance between the plates is the same.

In order to ensure the purification effect, whether it is a pure high-voltage model or a high-low voltage model, there will not be only one electrostatic module installed inside the device. The larger the air volume, the more electrostatic modules.

In theory, both high and low voltage electrostatic type and pure high voltage electrostatic type can be used for oil fume treatment, but high and low voltage electrostatic type is mainly suitable for working conditions where the oil fume is relatively "pure", such as kitchen fume, food factory fume, machine oil fog, etc. The pure high-voltage electrostatic treatment has a wider range of objects, which can not only purify oil fume, but also purify exhaust gas, flue gas and some peculiar smells, so it is mainly suitable for mixed treatment conditions of oil fume, exhaust gas and flue gas (in the industry, it is called oily exhaust gas, oily exhaust gas and oily exhaust gas). waste gas, wet waste gas), such as waste gas from resin processing, plastic waste gas, heat treatment waste gas, setting machine waste gas, etc. Under the premise of the same air volume, when the pure high pressure model is used alone to deal with pure oil fume, its oil removal effect is weaker than that of the high and low pressure model. When the high and low pressure models are used to treat oily exhaust gas, the exhaust gas treatment effect is weaker than that of the pure high pressure models, and the service life of the electrostatic module will be affected.

Because the two types of equipment have their own advantages and disadvantages, in the industrial oil fume treatment condition, the combination of the two equipment is a better solution, which can not only ensure the purification effect, but also reduce the cleaning cycle and prolong the service life of the electrostatic module. When the project budget is particularly limited, consider choosing one of the devices according to the working conditions. However, there is a new option to solve this contradiction. By improving the modular design structure, grass green can currently integrate high and low voltage electrostatic modules and pure high voltage electrostatic modules on one device, but it needs to be targeted according to specific working conditions by the combination design.
