Abstract
The utility model relates to a filter for filtering mineral oil in the oil processing process. The filter proceeds improvement to the existing technique, and the scheme is that firstly original steel bars arrangement type skeleton is improved to a stainless barrel structure with round holes; secondly the filter screen adopts filter material welded into a barrel sleeve covering the skeleton, while the filter material is made of stainless steel fiber felt with filtration accuracy of 25 micrometres agglutinated with stainless steel screen. Compared with prior art, the filter of the utility model has the maximum characteristic of improving voidage which increases from original 2. 5% to present 70%, the dirt accommodation capacity reaches 30mg/cm<2>, and the continuous running period of the filter is 20 days, so the working efficiency increases dozens of times for the improved voidage and running period.
Description
Technical field: the utility model relates in the petroleum refining process, be used for a kind of filter that cured oil filters.
Background technology: at the utility model in the past, cured oil filters the filter of usefulness, and its structure is outside the ring skeleton that reinforcing bar is arranged, and the 25 microns distances in interval are being twined the stainless steel wire of width 1mm.When cured oil passes through, will be filtered off greater than 25 microns impurity.The condition of work of cured oil strainer is: 1, medium: 120 ℃ cured oil; Operating pressure: 1.6Mpa; Kinematic viscosity: in the time of 80 ℃, be 46mm/s.Because the filter voidage of this winding-type is 2.5% only, resistance is big during work, and pollutant holding capability is little, and the space often is blocked again, needs flushing repeatedly to use again, flushing in 7 days once, so operating efficiency is very low.
Summary of the invention: for overcoming the deficiency that existing filter exists, increase work efficiency, filter of the present utility model improves prior art, and its way is: 1, with the skeleton of original reinforcing bar arranged type, change the tubular structure by the band circular hole; 2, to adopt filtering accuracy be that 25 microns stainless steel fibre felt is rolled up around knot filter material together with stainless (steel) wire and is welded into cylindrical sleeve outside skeleton to filter screen.A kind of filter of the present utility model and prior art are that voidage has improved than maximum characteristics, by original 2.5%, bring up to now 70%, and water environment capacity reaches 30mg/cm
2, cycle of oparation 20 days is because voidage and the raising of service cycle make operating efficiency improve original tens times.
Description of drawings: accompanying drawing, be a kind of structure of filter schematic diagram.
The specific embodiment: for a kind of structure of filter of the present utility model is had further understanding, accompanying drawings is as follows:
A kind of filter in the utility model, be that corrosion resistant plate by the band circular hole among the figure is rolled into skeleton 3 cylindraceous, what be enclosed within skeleton 3 outsides is that 25 microns stainless steel fibre felt and stainless (steel) wire sintering filter material together are rolled into cylinder, the seam filter screen 2 with the roll welding welding with filtering accuracy, forms with the T-Ring that is connected with work system 1 that is welding at filter screen 2, skeleton 3 two ends.
Claims (1)
1, a kind of filter, it is made up of T-Ring (1), filter screen (2) and skeleton (3), it is characterized in that adopting the skeleton (3) of the stainless steel cylinder of being with circular hole and roll up filter screen (2) that be welded into, that be enclosed within skeleton (3) outer cylindrical with stainless steel fibre felt and stainless (steel) wire sintering filter material together.
