Description

A kind of electrical adsorption desalting device

Technical field

Waste water control equipment is the utility model is related to, more particularly, to a kind of electrical adsorption desalting device.

Background technology

In the more solution of processing metal ion content, typically handled by way of Electro Sorb.Existing electricity Adsorption cleaning equipment is provided with waste water inlet 102 and wastewater outlet 103 referring to Fig. 1, including a casing 100 on casing 100, Be provided with several electrodes 101 for traversing whole cabinet wall in the casing, the adjacent electrode 101 respectively with power supply just Negative pole is connected, therefore electric field can be formed between adjacent electrode, and electrode 101 is made by that can pass through the carbon fiber silk floss of water.Make Used time, waste water flow into casing from waste water inlet, after the filtering and suction-operated of multiple electrodes 101, then gone out from waste water Mouth 103 flows out.After the time of one end, electrode adsorption reaches saturation state, at this time again pulls out electrode, and short circuit is with laggard Row rinses, and then places into casing.

This structure has a problem that for waste water when casing is just entered, ion concentration is maximum, later by step by step When filtering, ion concentration gradually reduces.This is resulted in, close when near the electrode adsorption saturation of waste water inlet The electrode of wastewater outlet does not all arrive also from adsorption saturation half.But it is up to standard in order to purify, as long as there is an electrode adsorption to satisfy The running of whole system will be stopped with us, backwashed.It is thus cumbersome, it is necessary to be improved.

The content of the invention

For the deficiencies in the prior art, the utility model provides a kind of electrical adsorption desalting device, can be significantly Reduce the frequency of electrode clean.

The utility model is achieved by the following technical solution：A kind of electrical adsorption desalting device, including casing, the case The first import and the second import are provided with body, several electrodes are provided with the casing, the electrode runs parallel is set, and adjacent The electrode be connected respectively with the both positive and negative polarity of power supply, an in addition to two-position four way change valve, the two-position four way change valve An import be waste water inlet, another import of the two-position four way change valve is wastewater outlet, two-position four-way commutation The one outlet of valve is connected with first import, another outlet of the two-position four way change valve and the second import phase Even.In use, we can first be used as the inflow entrance of waste water, after running a period of time, two-position four-way commutation using the first import Vavle switching so that inflow entrance of second import as waste water, flow export of first import as waste water, so toggle, just It can guarantee that the amount of ions adsorbed on all electrodes is all similar, avoid electrode of original product close to waste water inlet side Too early adsorption saturation and caused by stop cleaning electrode situation, be so also considerably reduced the frequency of electrode clean.

In above-mentioned technical proposal, it is preferred that ion detection device and 3-position 4-way commutation are provided with the wastewater outlet Valve, the ion detection device are connected with the wastewater outlet of the two-position four way change valve, and the one of the three position four-way directional control valve Individual import is connected with the ion detection device, another import of the three position four-way directional control valve and the second import phase Even, the one outlet of the three position four-way directional control valve is connected with follow-up wastewater treatment equipment, the three position four-way directional control valve Another outlet is connected with first import, under normal circumstances, the three position four-way directional control valve by the waste water with it is follow-up Wastewater treatment equipment connects, and when the ion detection device detects that ion concentration is exceeded, and the two-position four way change valve will When waste water imports first import, the waste water is imported into first import by the three position four-way directional control valve, when described Ion detection device detects that ion concentration is exceeded, and when waste water is imported second import by the two-position four way change valve, The waste water is imported into second import by the three position four-way directional control valve.

The utility model has the advantages that：In use, we can first be used as the inflow of waste water using the first import Mouthful, after running a period of time, two-position four way change valve switching so that inflow entrance of second import as waste water, the first import As the flow export of waste water, so toggle, it is ensured that the amount of ions adsorbed on all electrodes is all similar, avoid Original product close to waste water inlet side electrode too early adsorption saturation and caused by stop cleaning electrode situation, so It is considerably reduced the frequency of electrode clean.

Embodiment

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：

Referring to Fig. 2, a kind of electrical adsorption desalting device, including casing 1, the first import 11 and are provided with the casing 1 Two imports 12, several electrodes 13 are provided with the casing 1, the electrode 13 be arranged in parallel, and the adjacent electrode 13 divides It is not connected with the both positive and negative polarity of power supply, in addition to a two-position four way change valve 2, an import of the two-position four way change valve 2 For waste water inlet, described another import of two-position four way change valve 2 is wastewater outlet, one of the two-position four way change valve 2 Outlet is connected with first import 11, and another outlet of the two-position four way change valve 2 is connected with second import 12.

Ion detection device 3 and three position four-way directional control valve 4, the ion detection device 3 are provided with the wastewater outlet It is connected with the wastewater outlet of the two-position four way change valve 2, an import and the ion of the three position four-way directional control valve 4 are examined Survey device 3 to be connected, another import of the three position four-way directional control valve 4 is connected with second import 12, the 3-position 4-way The one outlet of reversal valve 4 is connected with follow-up wastewater treatment equipment（Not shown in figure）, the three position four-way directional control valve 4 it is another One outlet is connected with first import 11.

Under normal circumstances, the three position four-way directional control valve connects the waste water with follow-up wastewater treatment equipment, works as institute State ion detection device and detect that ion concentration is exceeded, and waste water is imported first import by the two-position four way change valve When, the waste water is imported into first import by the three position four-way directional control valve, when the ion detection device detect from Sub- concentration over-standard, and when waste water is imported second import by the two-position four way change valve, the three position four-way directional control valve will The waste water imported into second import.

In use, we can first be used as the inflow entrance of waste water, after running a period of time, two-position four-way using the first import Commutate Vavle switching so that inflow entrance of second import as waste water, so flow export of first import as waste water, switchback Change, it is ensured that the amount of ions adsorbed on all electrodes is all similar, avoid original product close to waste water inlet side The too early adsorption saturation of electrode and caused by stop cleaning electrode situation, be so also considerably reduced the frequency of electrode clean Rate.
