Abstract

The utility model relates to an industrial water purifier by multi-stage countercurrent process. The utility model solves the problems of big occupying area of complicated process, non-ideal water purity, long time consuming for shutdown backwashing, high cost, low production efficiency, big consumed energy, etc. of the present industrial service water purifying device. The utility model is characterized in that a multistage filter, a multistage booster pump, countercurrent devices which are connected in series (parallel), a testing instrument and an e electric appliance are installed in a box body and are connected with each other. The impurity, such as colloid, micro-particles, organics, bacteria, metal ion, radioactive substances, etc. that exist in water can be removed, and the purity can be reached to 18 M omega (6 mu S/M). The industrial water purifier by multi-stage countercurrent process has the advantages of continuous producing pure water, stabilization, low consumed energy, small ground occupation, automatic operation, no stop backwashing, long service life and low operation cost. The industrial water purifier by multi-stage countercurrent process is widely used for various raw water (subterranean water, surface water, tap water), and can be used for preparing high purity water which are required by electron, food product, beverage, brewing and pharmacy industry.

Description

Industrial multistage regurgitation infiltration system pure water device

The utility model belongs to the desalt technical field, especially belongs to a kind of system pure water device.

Existing industrial system pure water device adopts vapor enrichment or ion-exchange or electrodialysis unit more, vapor enrichment system pure water utmost point power consumption and time-consuming, and water purity is not high yet; Ion exchanged water uses yin, yang ion exchange tower or zwitterion to mix the exchange bed, needs often to use strong acid, highly basic backwash in system water process, operates complicatedly, and the cost height is gone back sewage effluent simultaneously; And the electrodialysis water production rate is little, power consumption big and need often to change dialyzer, also has the high problem of cost, and said apparatus also has various requirement to former water, and adaptability is extensive inadequately.

The purpose of this utility model be solve that the existing floor space of existing industry system pure water device is big, complex procedures, water purity are not ideal enough, shut down the backwash problems such as this height, production efficiency is low, power consumption is big that grow up to consuming time; provide a kind of except that all colloids, particulate, organism, bacterium and impurity such as metal ion, radioactive substance in anhydrating; its purity can reach 18M Ω (or 6 μ S/M), the pure water of making continuously, stable, power consumption is low, floor space is little, fully automatic operation, not shut down backwash, long service life, working cost low.Be widely used in various former water (underground water, surface water, tap water), can be used for electronics, food, beverage, brewage, the industrial multistage regurgitation infiltration system pure water device of the preparation of the required high purity water of pharmaceutical industries.

Industrial multistage regurgitation infiltration system pure water device adopts technical scheme as follows: it has a casing (1), one to multiple level is installed on the support of casing gives filtration unit (7,8,9,10), regurgitation permeator (5,6), automatic back-washing device (18), electrical control part (2), the filtration units that give at different levels are interconnection by pipeline, connect multistage pump intake and backwashing pump water outlet then, two pipelines respectively have valve control respectively, the water outlet of stage pump links to each other with the regurgitation permeator by pipeline, and above-mentioned each device is connected with electrical control part with detecting instrument respectively; Give filtration unit and adopt one to multiple level string (also) connection connections such as (1) sand-bed filter (2) robust fibre body (3) gac (4) hollow fiber microfiltration membrane (5) hollow fiber ultrafiltration membrane (6) activated carbon fiber; The regurgitation permeator adopt to twine the regurgitation permeator that the composite membrane of the cellulose acetate membrane of roll type or cellulose acetate and polymeric amide is made, can single or string (also) connection use; The automatic back-washing device is by the set(ting)value of detecting instrument and reverse water pump automatic back-washing, and backwash is to use product water to giving the counterflush of filtration unit and regurgitation permeator.

Principle of the present utility model is: former water gives filtration and successively the impurity of diameter 1 μ-10 μ, 0.1 μ-1 μ, 0.01 μ-0.1 μ is removed through at different levels, last regurgitation permeator is removed the above impurity of 0.0001 μ, impurity such as underwater gold belongs to and other is inorganic, organic, bacterium, microorganism so just can obtain high purity water all greater than this diameter.

Advantage of the present utility model is: various apparatus integrations, and aesthetic in appearance, the operation compactness, floor space is little, and is easy to operate directly perceived, the level of automation height, be applicable to various former water (underground water, tap water, surface water), complete machine current consumption is little, and water production rate is big, the water quality based on very high purity, use product water promptly back-washable, reduce environmental pollution, have the water quality monitoring (WQM) instrument on the device, quality product is carried out direct Monitoring and Controlling.

Below in conjunction with accompanying drawing the utility model is described in further detail:

The utility model is to be main body by a casing 1, and the multistage filtration unit 7,8,9,10 that gives is arranged on box bottom, by water pump 11 former water is sent into to give by pipeline and filters in 7, filters 8,9 by giving successively via pipeline, filters 10 by giving of parallel connection at last; Finish to give entering regurgitation permeator 5 by pipeline after filtering water passes through multistage booster water pump 12 superchargings, then enter regurgitation permeator 6 in parallel by pipeline, effusive pure water is product water 6 from installing.Above-mentioned all runnings all realize by switchboard 2, have on the switchboard 2 that the controller 4 of detection, under meter 3, system normally show 14, bound water monitor 15, pressure alarm 16, pipeline cross (owing) and press protector 17, backwash controller 18 and form with each water pump control linkage.Product water quality can directly be read by detecting controller (TDS instrument or conductivitimeter) 4, if the product deteriorating water quality is during to set(ting)value, system can use each filtration unit of product water backwash to the scheduled time automatically; The water quality of the utility model output can be up to the industrial high purity water of 18M Ω purity.

Give filtration and regurgitation permeator progression and series and parallel mode then according to former water foreign matter content, product water quality requirement and water production rate decide its concrete scheme.
