Coalescence dehydrated oil filter cart_Aite(Henan) environmental protection equipment Co.

Product introduction

At present, there are many methods of oil and water separation at home and abroad, and the oil dehydration method is more common in industry. According to its principle of action, it can be generally divided into three categories: physical dehydration method, chemical dehydration method and physical chemical dehydration method.

The principle of physical and chemical dewatering method is to use some hydrophilic or absorbent materials, so that the tiny water droplets contained in the oil are adhered to the surface of the material and formed into large water droplets or directly adsorbed, so as to achieve the separation of oil and water. The common physical and chemical dewatering methods include adsorption and fiber filter element coalescence dewatering.

Adsorption method is the use of good absorbent polymer adsorbent and other materials, the oil contained in the free water and emulsion water absorption, to achieve the separation of oil and water. The molecular structure of the polymer adsorbent is like a complex network, it will expand after absorbing water, but it is insoluble in oil and water. Because the polymer adsorbent has polar groups, and water molecules for polar molecules, so the adsorbent is easy to form hydrogen bonds with water molecules, polymer adsorbent absorption of water weight in the oil can reach 10~20 times its weight. But absorbent materials will quickly reach its saturation, and the cost of polymer adsorbent is high, so the adsorption method is generally suitable for oil water content is very low occasions.

Fiber filter element coalesce dewatering method has been widely used in domestic and foreign markets because of its high dehydration efficiency, large processing capacity, simple equipment structure, convenient operation and maintenance, etc., commonly used dehydration equipment filter separator is mainly composed of cylinder, detachable end cover, coalesce filter element, separation filter element, sink and import and export pipeline structure, its core component is coalesce and separation filter element, The main material of the bonding filter element is hydrophilic glass dimension, and the main material of the separation filter element is hydrophobic TEFLON (polytetrafluoroethylene mesh).

The general process of coalescing dehydration is that some water content of the oil enters into the interior of the coalescing filter element through the oil pipeline, and then successively through the filter layer of the coalescing filter element, demulsification layer, coalescing layer, etc., so that the tiny water droplets in the oil constantly coalesced into large water droplets, under the action of gravity constantly settling into the tank; The dehydrated oil enters the inside of the filter element through the outer surface of the separation, and then flows out of the filter separator through the oil outlet line. The separation filter element can also prevent the entry of small water beads; The water deposited in the collecting tank can be discharged by the drain port, so as to realize the separation of oil and water.
