Description
Technical field
The present invention relates to the purifier technical field, relate in particular to a kind of high precision high flow rate micropore ceramic tube.
Background technology
Micropore ceramics as filtering material use in the water treatment facilities, because of possessing lot of advantages, for example cost is lower, can conveniently clean after the obstruction, flow is all replied basically after cleaning, and filtering accuracy does not descend, and filter process can keep water stabilization from start to finish, or the like, so be used widely at present.
The micropore ceramics that uses in the water treatment facilities is made generally in tabular, tubulose or hemispherical.Current enter from a side during filtration, flow out from another side, and pollutant is blocked in an into side surface of water, and on this surface deposition or gather and form filter cake.Carrying out along with filter process, filter cake thickness is more and more thicker, filtration resistance is increasing, though effluent characteristics can not descend, but water flow is more and more littler, final flow can not meet the demands, and at this moment needs micropore ceramics is cleaned to remove the pollutant or the filter cake of ceramic surface, recovers filtering traffic.People wish in the given time and under the given filtering accuracy condition, the water yield of filtration is the bigger the better.This is actually flow resistance and the water environment capacity that has reflected micropore ceramics.When filtering precision one regularly, water environment capacity is main relevant with the filter area of micropore ceramics, and flow resistance is not only relevant with filter area, and is also relevant with the thickness of filter bed of micropore ceramics.
For the tubulose micropore ceramics, a kind of method is to increase filter area by the radical that increases micropore ceramic tube, device structure complexity like this, and cost is higher; Another kind method is to increase filter area by the diameter that increases micropore ceramic tube, and the space in the micropore ceramic tube just wastes like this, and it is very huge that equipment will become.Obviously, such two kinds of methods all make equipment manufacturing cost obviously rise.
Micropore ceramics is that a kind of intensity is lower, and more crisp, frangible material, in order to guarantee micropore ceramics enough intensity is arranged, and the tube wall of tubulose micropore ceramics is all thicker in the known technology, about 8 millimeters or thicker.In the known technology, the pipe thickness of tubulose micropore ceramics is exactly a thickness of filter bed, and this just causes flow resistance bigger.Exactly, have breakthrough on prior art, be the thickness of filter bed that will reduce micropore ceramics on the one hand, is to increase filter area in given volume range as far as possible on the other hand.
Summary of the invention
The objective of the invention is provides a kind of high precision high flow rate micropore ceramic tube at above-mentioned prior art present situation, this micropore ceramic tube is mainly used in the filtration drinking water, also can filter similar sanitary liquid, compared with prior art, its advantage is: thickness of filter bed is thin, and flow resistance is little, is guaranteeing under the prerequisite that filtering accuracy does not reduce, can improve the filtered water flow, thus make filter plant can design volume less, cost is lower.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of high precision high flow rate micropore ceramic tube, it adopts filtering accuracy to have two kinds of material manufacturings of significant difference, be provided with the superficial layer (filtering layer) that adopts the higher material of filtering accuracy to make on the water inlet surface of micropore ceramic tube, remainder adopts the very low material manufacturing of filtering accuracy, and wherein thickness of filter bed is less than 2 millimeters.
Thickness of filter bed is the one of the main reasons that influences filtration resistance, so, should reduce thickness of filter bed as far as possible.Those skilled in the art will appreciate that the thickness of filter bed of the micropore ceramic tube of the technology of the present invention can be made thinner, for example less than 1 millimeter.
The technology of the present invention also comprises: the water inlet surface at micropore ceramic tube is provided with convex tendon or groove, and the situation thin for tube wall is provided with convex tendon, and the situation thicker for tube wall is provided with groove.Groove or convex tendon are set all can increase filter area, increase the water environment capacity of micropore ceramic tube and reduce filtration resistance.Described convex tendon or groove can be arranged on the outside of micropore ceramic tube, also can be located at the inboard of micropore ceramic tube, preferably are located at the outside of micropore ceramic tube.The shape of convex tendon or groove can be the vertical bar shaped parallel with the micropore ceramic tube axis, can be scroll, also can be annular.
Micropore ceramic tube of the present invention can be made the form that single face filters, and also can make the form of two-sided filtration.
For the micropore ceramic tube that single face filters, its outer surface is the water inlet surface, and its inner surface is for going out water surface.Be provided with the thin list surface layer (filtering layer) that adopts the higher material of filtering accuracy to make, the filtration of thin list surface layer at outer surface; Remainder adopts the very low material manufacturing of filtering accuracy, plays water conservancy diversion and structural strength effect.This single face filtering micropore ceramic pipe can set out water swivel by an end therein in use, at the other end stifle is set; Also a water out adapter can respectively be set at two ends.Current enter tube wall from outer surface during filtration, pass inner layer material again and enter in the micropore ceramic tube, flow out from water out adapter at last, as shown in figure 13.
For the micropore ceramic tube of two-sided filtration, its structure is that an end has the big opening of the end other end, and the end surfaces and the inner surface at the end of the outer surface of its tube wall, inner surface, big openend are into water surface.All water inlet surfaces are equipped with the thin list surface layer (filtering layer) that adopts the higher material of filtering accuracy to make, this thin list surface layer filtration; Remainder adopts the very low material manufacturing of filtering accuracy, plays water conservancy diversion and structural strength effect.In order to reduce the flow resistance of current in the lower material of filtering accuracy, in this part material, flow-guiding channel is set.This two-sided filtering micropore ceramic pipe is provided with water out adapter at the end that the end is arranged in use.Current enter micropore ceramics from each water inlet surface during filtration, flow to flow-guiding channel and water out adapter, flow out from water out adapter at last, as shown in figure 14.
