Embodiment Construction

[0010] Such as figure 1 , 2 As shown, the electrostatic ceramic fine filter includes a filter cylinder, an electrostatic generator (static electrode), a porous honeycomb sponge body, and an airflow-ultrasonic cleaning device. There is an oil inlet 1 and an oil discharge port 3 on the filter cylinder, and a porous honeycomb sponge body 10 is installed in the filter cylinder body. The porous honeycomb sponge body 10 is ring-shaped and has a plurality of ceramic filter rods 7 and static electrodes 6 in its center. The porous honeycomb sponge body is tightly applied to the ceramic filter element group. The ceramic filter rod 7 and the static electrode 6 are fixed on the filter element carrying bracket 9, and the filter element carrying bracket 9 is sealed and installed on the opening of the filter cylinder, and the oil outlet 2 is opened on the filter element carrying bracket 9. A pressure sensor 11 is installed on the filter cylinder, and an ultrasonic vibrator 8 is installed b...

Abstract

The invention belongs to an electrostatic ceramic fine filter in the separation technology, comprising a filter cylinder body, an oil inlet and an oil discharge outlet are arranged on the filter cylinder body, the interior of the filter cylinder body is provided with a porous cellular sponge body, the porous cellular sponge body is annular, the center of the body is provided with a plurality of ceramic filter rods and electrostatic poles, the ceramic filter rods and the electrostatic poles are fixed on a filter core bearing bracket, the filter core bearing bracket is sealed and arranged on theopening of the filter cylinder body, and an oil outlet is arranged on the filter core bearing bracket. An electrostatic filter device which is adopted by the electrostatic ceramic fine filter utilizes the strong electrostatic field to effectively filter and remove the impurities which are as fine as 0.01 micron and absorb and block a great number of granular pollutants and the oxidation substances in the porous cellular sponge body, thereby providing the new electrostatic ceramic fine filter which has high filtration precision, low use cost, difficult blockage and easy regeneration.

Description

technical field [0001] The invention belongs to the technical field of separation, in particular to a filtering device for oil products in the petrochemical industry. Background technique [0002] At present, there are many types of filters for oil filtration and purification, but there are common problems of low filtration accuracy, easy clogging, and high cost of use. For example, oil filters made of ceramic filter materials are commonly used. General filter devices for ceramic substrates only use the capillary principle of ceramic micropores to achieve solid-liquid separation. Ceramic micropores are generally between 0.1-10 microns, and the accuracy cannot be improved any more. Particle impurities smaller than 0.1 microns cannot be filtered out. Furthermore, due to reasons such as cost and equipment volume control, the surface area of ​​the filter element of the equipment is limited, so it is particularly easy to block. Contents of the invention [0003] The purpose o...
