Oil product purification membrane filtration system and use process thereof

Abstract

The invention belongs to the technical field of petrochemical engineering and environmental protection, and particularly relates to an oil product purification membrane filtration system and a use process thereof. The system comprises a primary sedimentation tank, a coarse filtration device, an oil product purification membrane assembly unit and an oil production tank which are sequentially communicated, the oil product purification membrane assembly unit comprises a plurality of oleophylic and hydrophobic membrane assemblies which are connected in parallel; each oleophylic and hydrophobic membrane assembly comprises an oil inlet, an oil outlet and a thick oil outlet; the oil inlets are respectively communicated with the coarse filtration device and a backwashing liquid collecting device;and the oil production tank is respectively communicated with a gas path cleaning unit, an oil path cleaning unit and the oil production tank. The technology aims at solving the problems that an existing filter element is low in filtering precision and large in pore diameter, and an oil product cannot meet the equipment use standard after one-time filtering; the membrane filtration system and process are high in filtration precision, and dehydration and impurity removal are completed at a time at normal temperature. The system is short in process, low in energy consumption, high in automationdegree, small in occupied area and easy to popularize in the industry.

Description

technical field [0001] The invention belongs to the technical fields of petrochemical industry and environmental protection, and in particular relates to an oil product purification membrane filtration system and a use process. Background technique [0002] Lubricating oil is the lubricant of modern industry and the "blood" of industrial equipment. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. During the use of lubricating oil, impurities such as moisture, dust, fibers, and metal chips will enter into the lubricating oil with the operation of the equipment and poor sealing, which will increase the pollution of the lubricating oil and affect the use effect. [0003] The annual sales volume of lubricating oil in my country is about 5 million tons, which are mainly used in industrial equipment and motor vehicles. As far as industrial equipment is using oil: traditional online oil purification devices are mostly glass fiber...

Problems solved by technology

This process needs to be heated above 100°C to evaporate water, and clay absorbs and filters impurities; this process consumes about 65 degrees of electricity per ton of oil for heating and evaporating water, and consumes about 60kg of clay per ton of oil. , the disposal cost is expensive, and the cost of processing one ton of waste oil is about 300 yuan

Traditional oil filter needs to be heated and evaporated to about 100°C to remove moisture; then the oil filter is repeatedly circulated to remove impurities. During the process, the filter element needs to be replaced frequently, the operating efficiency is low, and the quality of the filtered oil is poor.
