Abstract
The utility model relates to a special totally-enclosed electrodialysis brackish water desalter for electrodialysis, which comprises a top cover plate 1, a bottom cover plate 5, a sealing gasket 2, a positive electrode plate 3, a negative electrode plate 4, a brackish water flow guiding hole channel 11, a fresh water flow guiding hole channel 12, female films 18 and male films 17, wherein, a set of female films 18 and male films 17 in alternate and orderly arrangement is additionally arranged in a cavity formed between the top cover plate 1 and the bottom cover plate 5 in parallel, and a brackish water flow returning hole channel 13 and a fresh water flow returning hole channel 14 are arranged in the bottom cover plate 5. The utility model has the characteristics of long flow path, high desalting efficiency, little power consumption, etc.
Description
The utility model belongs to a kind of isolated plant that utilizes electrodialysis to separate the saliferous brackish water.
At present, existing electrodialytic desalting device is made up of lamina tecti, bottom plate, gasket seal, positive electrode, negative potential, water conservancy diversion duct and one group of spaced positive and negative ion semi-permeable membranes, the former water of this electrodialytic desalting device flows to from an end, solution after the separation desalination flows out from the other end, therefore, the electrodialytic desalting flow process is short, and desalting efficiency is poor.
The purpose of this utility model provides the totally-enclosed electrodialysis brackish water demineralizer of a kind of desalination long flow path, desalting efficiency height, little power consumption.
For achieving the above object, technical scheme provided by the utility model is a kind of totally-enclosed electrodialysis brackish water demineralizer, it comprises lamina tecti, bottom plate, is located at the cavity block and the anode membrane of the gasket seal in the formed cavity, positive electrode plate, negative electrode plate, dense water water conservancy diversion duct, fresh water water conservancy diversion duct and one group of interval ordered arrangement between lamina tecti and bottom plate, between lamina tecti and bottom plate, add one group of cavity block and anode membrane of ordered arrangement at interval in the formed cavity more side by side, establish concentrate recirculation duct and fresh water backflow duct in the bottom plate.
Compare with existing electrodialytic desalting device, because the utility model adopts two groups of yin, yang EDBM desalinations.Therefore electrodialysis long flow path, the desalting efficiency height, the unit time water production rate is big, current consumption is few, intake-outlet can be opened the end at demineralizer.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of the totally-enclosed electrodialysis brackish water of the utility model demineralizer.
Fig. 2 is the part sectioned view after totally-enclosed electrodialysis brackish water demineralizer adds shell.
Fig. 3 is the vertical view of totally-enclosed electrodialysis brackish water demineralizer shown in Figure 2.
Among the figure, 1 lamina tecti; 2 gasket seals; 3 positive electrode plates; 4 negative electrode plates; 5 bottom plates; 6 former water inlets; 7 utmost point water outs; 8 water outlets; 9 dense water outs; 10 utmost point water water conservancy diversion ducts; 11 dense water water conservancy diversion ducts; 12 fresh water water conservancy diversion ducts; 13 concentrate recirculation ducts; 14 fresh water backflow ducts; 15 utmost point water backflow ducts; 16 utmost point hydroeciums; 17 anode membranes; 18 cavity blocks; 19 dense hydroeciums; 20 freshwater rooms; 21 shells; 22 membrane stacks.
Totally-enclosed electrodialysis brackish water demineralizer shown in Figure 1 is secondary eight segment structures, is promptly discharged behind eight electrodialysis processes by two groups of orderly cavity block 18, anode membrane 17 and former water of arrangement arranged side by side.The former water of saliniferous flows in the demineralizer from former water inlet 6, and alternating current is through water conservancy diversion duct and hydroecium again.Flow into the former water of the totally-enclosed intravital saliferous in electrodialysis brackish water demineralizer chamber under effect of electric field, the yin, yang ion constantly enters dense hydroecium 19, and makes density loss because of the yin, yang ion constantly shifts out in the freshwater room 20, thereby has finished the electrodialysis process of former water.Solution after electrodialysis separates is divided into containing the higher dense water of yin, yang ion and containing concentrate recirculation duct 13 and 14 backs, fresh water backflow duct that the lower fresh water of ion flows through respectively in the bottom plate 5 and flows out from dense water out 9 and water outlet 8.
For will wherein only being arranged near the utmost point hydroecium 16 of battery lead plate, sun or anionic utmost point water discharges from utmost point water out 7, between totally-enclosed electrodialysis brackish water demineralizer lamina tecti 1, bottom plate 5, also be provided with utmost point water water conservancy diversion duct 10 in the formed cavity, be provided with utmost point water backflow duct 15 in the described bottom plate, be connected with utmost point water water conservancy diversion duct 10.
Fig. 2, Fig. 3 are the part sectioned views after totally-enclosed electrodialysis brackish water demineralizer adds shell 21, promptly also are provided with shell 21 outside described lamina tecti 1, bottom plate 5.Reach antiseep, protection against electric shock.Membrane stack 22 is two groups of cavity block 18, anode membranes 17 of ordered arrangement at interval.
The lamina tecti 1 of above-mentioned totally-enclosed electrodialysis brackish water demineralizer is provided with water-in 6, water outlet 8, dense water out 9.Reach the function that has entery and delivery port on the panel simultaneously.
