Description
(1) technical field:
The utility model relates to a kind of industrial filter, is specially a kind of micropore sintered fine filter.
(2) background technology:
In industries such as chemical industry, light industry, metallurgy, mine, generally all to use filter plant in order to obtain purer gas or liquid, what wherein use always is fine filter.As publication number is CN2325099, the name be called＜＜the automatic backwash fine filter Chinese utility model patent, a kind of automatic backwash fine filter is disclosed, it comprises a container body, and charging aperture and discharging opening are arranged on the container body, and the backwash mouth also is housed on the container body, the backwash mouth is connected with discharging opening through the backwash parts, and be connected with container inner filtration internals, described filtration internals adopt micropore degree of depth type filter material, radially pleated construction; On the container body, also has sewage draining exit.This utility model has automatic backwash, filter area is bigger, continuous type characteristics, but the filtering accuracy that this automatic backwash fine filter can reach is not ideal enough.
(3) utility model content:
The utility model will disclose the high micropore sintered fine filter of a kind of filtering accuracy.
This novel microporous sintering fine filter, comprise cylindrical shell, be arranged at the collector tube box in the cylindrical shell and be threadedly connected to screen pipe on the collector tube box, the bottom of cylindrical shell is provided with water inlet and slag-drip opening, and the collector tube box is connected by the outer efferent duct that catchments of drain pipe and cylindrical shell; Wherein said screen pipe is formed by the polyethylene powder sintering of low pressure super high molecular weight, and the aperture of filtering micropore is the 0.5-3 micron on the screen pipe.
The cylindrical shell of described micropore sintered fine filter can be made the round bottom formula, also can make awl end formula, also can make other shape certainly as required; Described collector tube box hangs and is arranged in the cylindrical shell, and screen pipe is threadedly connected to the bottom of collector tube box; Described slag-drip opening preferably is arranged at the minimum point place of cylindrical shell bottom, so that when deslagging the deposit in the cylindrical shell is all discharged.
The aperture of filtering micropore is preferably 1 micron on the described filtration body.
The internal diameter of the screen pipe that uses in this novel microporous sintering fine filter is generally the 5-60 millimeter, because screen pipe is to work under certain pressure condition, is crushed in order to prevent screen pipe, requires the tube wall of screen pipe to reach certain thickness; According to the service condition of screen pipe, in above-mentioned inside diameter ranges, the wall thickness of screen pipe is comparatively suitable with the 2-15 millimeter; Superiority with cost performance considers that then preferred internal diameter is the 10-25 millimeter, and wall thickness is the 6-10 millimeter.
Described collector tube box is separated into 2-9 by the dividing plate with axially parallel and organizes mutual disconnected collect cavity, and every group of collect cavity is connected by the outer efferent duct that catchments of drain pipe and described cylindrical shell respectively, is equipped with by-pass valve control on the described every drain pipe; Such design makes the waste liquid amount that can handle as required in actual production select wherein one group or several groups of screen pipes to carry out work, can reduce the loss of equipment virtually, improves the service life of equipment; Also can be therein one group or several groups of screen pipes when occurring stopping up, close corresponding system valve, and do not influence proceeding of filtration.
The applicant is through in a large number, experiment draws repeatedly: when the height of this novel microporous sintering fine filter and diameter ratio value were 1.5-1.7, the filter effect effect that is reached was best.
After waste liquid of need handling or water enter cylindrical shell from micropore sintered fine filter cylindrical shell bottom water inlet, at the filtering micropore infiltration pipe from the screen pipe under certain pressure, flow out through the collector tube box less than the medium in filtering micropore aperture; Be trapped within the outer surface of screen pipe greater than the solid particle in filtering micropore aperture, form filter cake, along with increase running time, filter cake also thickens thereupon, and pressure reduction is also increasing; For prevent filter cake pressed tension and increase the difficulty of screen pipe regeneration, the inlet outlet pressure differential during this novel microporous sintering fine filter operation is generally≤0.2MPa.
The regeneration of described screen pipe can adopt the air of band pressure to carry out blowback,, can use gas-liquid instead and mix the method for blowing when bad as the effect of blowback; When said method all can not reach desirable effect, also can adopt chemical method that screen pipe is regenerated, described chemical regeneration liquid can be the hydrochloric acid solution that volumetric concentration is 10-15%, also can prepare suitable regenerated liquid according to the composition in the filter cake certainly.
The screen pipe internal diameter that this novel microporous sintering fine filter adopts is that 5-60 millimeter, wall thickness are the 2-15 millimeter, the aperture is the filtering micropore of 0.5-3 micron on the combined filtering body, make its filter area big, filter the water quality height of back clear water, in above-mentioned internal diameter and wall thickness range, screen pipe withstand voltage effective, long service life; In addition, this novel microporous sintering fine filter is with respect to existing fine filter, have that volume is little, filtering accuracy is high, cost is relatively low and oil resistant, corrosion-resistant, the characteristics that are easy to safeguard, also can be widely used in the liquid-solid separation that technology is filtered and " three wastes " are handled of industries such as oil field underground flooding, chemical industry, light industry, metallurgy, mine, machinery, plating, weaving, food and drink according to the treating capacity of the treating capacity conditioning equipment of waste liquid.
