Abstract

The utility model provides an Electronic Data Interchange (EDI) module flow control device, which comprises at least two EDI modules; the input end of each EDI module is connected with a main concentrate inlet pipe and a main pure water inlet pipe; a main regulating valve is respectively arranged on the main concentrate inlet pipe and the main pure water inlet pipe; the main concentrate inlet pipe and the main pure water inlet pipe respectively comprise a branch concentrate inlet pipe and a branch pure water inlet pipe; a pure water regulating valve is arranged on each branch pure water inlet pipe; and the pure water regulating valve is connected with a flow meter. By adopting the technical scheme that the flow meters are designed for each EDI module pure water inlet pipe and the concentrate inlet pipe, the EDI module flow control device regulates the water inlet of each EDI module, so that the use rate of each EDI module is average; and the processing capability and use conditions of each EDI module can be judged through the flow read from the flow meters, so that the technical problem of the prior art that the water production of all the EDI modules is not uniform.

Description

EDI module flow rate control device

Technical field

The utility model relates to a kind of EDI system, particularly a kind of EDI module flow rate control device.

Background technology

Because high purity water has a wide range of applications in fields such as biotechnology, electric power, electronics, medical and health, chemical industry, scientific researches, so the device of various preparation high purity waters also arises at the historic moment.At present, the technology of preparing of high purity water device mainly adopts electrodeionization (EDI) technology.

Electrodeionization (EDI) technology is the combination of electrodialysis and two technology of ion-exchange, i.e. filling ion-exchange resin in electrodialysis freshwater room dividing plate, it had both kept the electrodialysis advantage that desalination and ion exchange resin can deep desalting continuously, had overcome negative impact and the trouble that ion exchange resin needs acid-alkali regeneration and the environmental pollution that causes of electrodialysis concentration polarization again; Further improvement to this technology; be to replace traditional mixed bed ion exchange resin to make pure water, high purity water with the EDI module; but different with mixed bed is; the ion exchange resin of filling in the EDI module freshwater room dividing plate can obtain regeneration automatically when work; can be unsaturated, therefore do not need the acid-alkali regeneration resin and shut down, can make that to produce the water process highly stable; and product water water quality is good, has reduced the operation and maintenance cost of pure water equipment to greatest extent.

The technology that existing EDI technology is used as shown in Figure 1, only is provided with a under meter at total pure water water inlet pipe and dense water water inlet pipe place, and this structure can only be regulated total pure water flooding quantity and dense water flooding quantity, and it is inhomogeneous to cause each EDI module to produce water like this.

The utility model content

The purpose of this utility model is to be to provide a kind of EDI module flow rate control device, to solve the uneven technical problem of each EDI module product water in the prior art.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of EDI module flow rate control device, comprise at least two EDI modules, the input terminus of described each EDI module all connects a total dense water water inlet pipe and a total pure water water inlet pipe, on described total dense water water inlet pipe and the total pure water suction culvert a total variable valve is set respectively, described total dense water water inlet pipe and total pure water water inlet pipe comprise one fen dense water water inlet pipe and one fen pure water water inlet pipe respectively, on described each branch pure water suction culvert a pure water variable valve are set.

Preferably, described pure water variable valve connection traffic meter.

Owing to adopted above technical characterictic, made the utility model have following advantage and positively effect than prior art:

The utility model provides a kind of EDI module flow rate control device, at every block of EDI module pure water water inlet pipe and dense water suction culvert design discharge meter, flooding quantity to every EDI module is regulated, the rate of utilization of guaranteeing every EDI module is average, the flow that can also read by under meter is judged the processing power and the practical situation of an EDI module.

Embodiment

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

Please refer to Fig. 2, a kind of EDI module of the utility model flow rate control device, comprise at least two EDI modules, in the present embodiment, comprise two EDI modules, the one EDI module 1 and the 2nd EDI module 2, the input terminus of each EDI module connects a total dense water water inlet pipe 3 and a total pure water water inlet pipe 4 respectively, one total dense water regulating valve 31 is set on total dense water water inlet pipe 3 tunnel, on total pure water water inlet pipe 4 tunnel a total pure water variable valve 41 is set respectively, total dense water water inlet pipe 3 and total pure water water inlet pipe 4 comprise one fen dense water water inlet pipe and one fen pure water water inlet pipe respectively, promptly the input terminus of an EDI module 1 is provided with one fen dense water water inlet pipe and one fen pure water water inlet pipe, one fen pure water variable valve 311 is set on minute pure water water inlet pipe, connected a under meter at first minute on the pure water variable valve 311, the input terminus of the 2nd EDI module 2 is provided with one fen dense water water inlet pipe and one fen pure water water inlet pipe, and one second fen pure water variable valve 312 is set on minute pure water water inlet pipe, connects a under meter at second minute on the pure water variable valve 312.

More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
