Description

Press micro-filtration in the pipeline type water treatment

The utility model belongs to the water treatment facilities technical field, is specifically related to a kind of the utilization in the pipeline type water treatment of microporous filter tube for medium and presses micro-filtration.

In existing water technology, conventional water treatment process mostly is provided with precipitation (clarification) pond and filtering ponds, finishes water purification by dosing coagulant and disinfectant and handles.In processing procedure, precipitation (clarification) pond needs regularly spoil disposal, and filtering ponds then need regularly and flushing, to keep good precipitation and filter effect.The shortcoming of this traditional water treatment facilities is that floor space is big, and the construction period is long, and gross investment and operating cost height are realized the automatic operating difficulty, and equipment can not move, and can't realize the batch process of batch production.In recent years, domestic also have the water treatment facilities that adopts microporous filter tube to come out, Chinese patent 90207685 " a kind of novel meticulous water filter " for example, it is that micropore sintered composite filter tube by many vertical setting of types is a filter core, the collect cavity of pipe box is communicated with the efferent duct that catchments with discharging tube, and utilization blowback mode is cleaned.Though said structure has improved the water treatment quality to a certain extent, but still there is following shortcoming: 1. have only one to export the outlet of promptly catchmenting owing to enter the water of filter, after all water filters through microporous filter tube, will stay a large amount of impurity, normally move, need carry out backwash continually for keeping filter, the blowback cleaning way that it adopts, need be equipped with equipment such as air compressor machine, gas tank, filter intermitten service, energy consumption is big, expense is high.2. adopt vertical installation, the connecting line complexity, switch valve is many.If extend to industrial water supply and sewage disposal, investment is big, automatic operating is difficult, finally causes the unit occupied area aquifer yield few.

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of and cleans simultaneously automatically in filter process, presses micro-filtration in the pipeline type water treatment that level is installed.

The purpose of this utility model is achieved in that

Press micro-filtration in the pipeline type water treatment, comprise shell body, source water inlet, clear water output, source water out, be provided with the filter chamber at forward and backward cloth hydroecium and middle part in the shell body, cut off by demarcation strip between them, forward and backward cloth hydroecium is established source water inlet and source water out respectively, and the filter chamber establishes clear water output; Be horizontally disposed with microporous filter tube in the filter chamber, the microporous filter tube two ends are fixed on the demarcation strip, rear water distributing chamber before the conducting.Microporous filter tube is established two at least.

Compare with existing micro-filtration water treatment facilities, the utility model has the advantages that:

1. the utility model need not carry out frequent high pressure gas, water associating backwash to keep normal filter process, and filter and do not need intermitten service, good processed water quality, turbidity is lower than 0.5NTV, and saving energy and expense are low.The utility model is established the source water out at rear water distributing chamber, when making current enter the filter chamber, part water filters outside flowing in the microporous filter tube because of the hydraulic pressure effect, another part then flows to rear water distributing chamber after microporous filter tube washes away the impurity of inner surface, flow out through the source water out again, flushing unites two into one to the filtration of processed water and to microporous filter tube like this, utilize the shearing force effect of current fluid, significantly reduce the deposition of impurity screening at the microporous filter tube inner surface, thereby greatly prolong the normal filtration time, when certain water treatment condition and the filtration parameter selected for use were appropriate, this normal filtration cycle was more than the several years.

2. the utility model installation station is horizontal, and is simple in structure, greatly improved the producing water ratio of unit occupied area.

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is the utility model structure chart;

Fig. 2 is a microporous filter tube cross section enlarged drawing.

Among the figure: 1. cloth hydroecium 5. rear water distributing chambers 6. filter chambers 7. source water inlets, 8. source water outs, 9. clear water outputs before shell body 2. microporous filter tubes 3. demarcation strips 4.

Embodiment: as shown in Figure 1, inside at filter housing body 1, demarcation strip 3 and the one group of horizontal microfiltration tube 2 that is fixed on the demarcation strip 3 are divided into three parts with the filter inner chamber, wherein preceding cloth hydroecium 4 is interconnected by microporous filter tube 2 with 5 two parts of rear water distributing chamber, and the 3rd part then is filter chamber 6.Forward and backward cloth hydroecium 4,5 is established source water inlet 7 and source water out 8 respectively, and filter chamber 6 establishes clear water output 9.

As shown in Figure 2, the utility model adopts special microporous filter tube to make filter element, and the fine filter opening of chimney filter tube wall is to be formed in the production technology of setting by material-structure.The technological process of adopting one-level or two-stage micro-filtration is the different requirements according to processed water quality and demand water quality, and selects the microporous filter tube of respective aperture for use, and it can filter silt particle, suspension and bacterium etc. effectively.

Operation principle of the present utility model is achieved like this: the filter of device on system and pipeline, can pass through water pump (head-tank, case) supplies water to filter, current are by preceding cloth hydroecium 4, demarcation strip 3, enter the inwall of microporous filter tube 2, utilize the osmotic pressure of water, filter by the chimney filter tube wall, various fine impurity are then stopped by the fine aperture of tube wall in the water, firmly partial impurities can " be blocked " in the solid netted duct that enters the having many bends or curves porous of tube wall, the fine impurity that is attached on the tube wall then forms filter membrane simultaneously, can be used as further sieving, the more fine impurities in cohesion and the adsorbed water.Clear water enters into filter chamber 6 by tube wall continuously like this, confluxes to clear water reserviors or water tank by pipe-line system again, and a large amount of thicker impurity then are deposited on the chimney filter inner surface, and the current that constantly flowed to the cloth hydroecium are taken away.Under improper filtercondition, such as source water quality more with exceed the permission process range for a long time, when change of water quality is big, the utility model can be dismantled easily, expose microporous filter tube, available then clear water washes or scrubs, and then can carry out low-pressure water and the flushing of blink easily for the screen pipe colony that is attached in the system.After using for a long time, the harmless cleaning agent that the utility model also allows to adopt particular arrangement to microporous filter tube carry out for the time long regeneration.When using the utility model and handle city tap-water, at the turbidity of regulation during less than 3NTV, when trying to achieve the clean water less than 0.5NTV (even less than 0.2NTV), the cycle of this washing and regeneration was more than the several years.

A plurality of combinations of above-mentioned filter then can adapt to the water treatment plant of the different disposal water yield.It extremely is suitable for low temperature, the low-cloudy water of the tap the latent power increase-volume and the numerous domestic of water treatment and handles.If adapted gives treatment facility efficiently, then the utility model can adapt to all lives, industrial water supply and sewage disposal.In addition, the utility model also can be used as the processing of giving of high purity water processing.
