The utility model is used for EDI regeneration is washd.

Description

EDI regeneration cleaning system

Technical Field

The utility model relates to a EDI regeneration cleaning system.

Background

The chemical water treatment desalting equipment adopts electric desalting equipment, is put into production in 2010, and originally adopts an EDI module to select roll-type EDI-210 products of DOW company. The quantity of the EDI modules is selected according to the condition that the water yield of the EDI modules cannot exceed 70 percent of the water flux of the EDI modules. The electrodeionization system has complete sequential control and interlocking protection functions. The processes of starting, running, stopping, standby and the like of the electric deionization system can be automatically controlled by a PLC.

After the EDI runs for a period of time, the voltage does not rise, so that the EDI module cannot be regenerated completely, and pollutants in the module are accumulated excessively.

Disclosure of Invention

The utility model discloses an it is not enough to prior art, the utility model provides a EDI regeneration cleaning system to solve the problem of proposing in the above-mentioned background art.

The above purpose is realized by the following technical scheme:

an EDI regeneration cleaning system comprises a cleaning box, a regeneration circulating water pump and two security filters, wherein a liquid outlet pipe of the cleaning box is respectively communicated with inlets of the two security filters, and liquid outlet pipes of the two security filters are communicated to a main discharge pipe;

the bottom outlet of the cleaning box is communicated with a circulating pipeline which is communicated to the liquid outlet pipe;

the recycling pipeline is provided with the regeneration recycling water pump.

The EDI regeneration cleaning system, the circulation pipeline with install the valve respectively on the drain pipe.

Has the advantages that:

1. the utility model provides a EDI operation a period after, the phenomenon that voltage rise does not fall causes EDI module regeneration not thorough, and the pollutant accumulation is too much in the module, through setting up EDI regeneration cleaning system, carries out forced circulation regeneration cleaning work, and help EDI membrane block resumes normal operating ability. And only high-purity water is used for cleaning, acid and alkali are not used, secondary pollution is not caused, and the environment is not polluted. Thereby ensuring the stable and economic operation of the desalting equipment.

2. The utility model discloses after increasing regeneration cleaning system, both guaranteed EDI's normal desalination effect, for the unit steady operation water provides the safety guarantee again, both eliminated the EDI voltage and risen and increase the running cost, eliminated the potential safety hazard of desalination equipment for the company again.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a system diagram of the present system in communication with an electric desalination system;

in the figure: 1. an electrical desalination system; 2. a regenerative cleaning system; 3. cleaning the tank; 4. a circulation line; 5. regenerating a circulating water pump; 6. a liquid outlet pipe; 7. a cartridge filter; 8. a liquid discharge pipe; 9. a main calandria; 10. a liquid inlet pipe.

The specific implementation mode is as follows:

example 1:

an EDI regeneration cleaning system comprises a cleaning box 3, a regeneration circulating water pump 5 and two security filters 7, wherein a liquid outlet pipe 6 of the cleaning box is respectively communicated with inlets of the two security filters, and liquid outlet pipes 8 of the two security filters are communicated with a main discharge pipe 9;

the bottom outlet of the cleaning box is communicated with a circulating pipeline 4 which is communicated with the liquid outlet pipe;

the recycling pipeline is provided with the regeneration recycling water pump.

Example 2:

according to the EDI regeneration cleaning system of embodiment 1, valves are respectively arranged on the circulating pipeline and the liquid outlet pipe.

The working principle is as follows: when the voltage of the original electric desalting system 1 rises, the cleaning effect is reduced, when the voltage rises to 300V, the original electric desalting system cannot perform cleaning work, the solution is introduced into the cleaning box through the liquid inlet pipe 10 and is cleaned through continuous circulation of the regeneration circulating water pump, the cleaned solution is introduced into the security filter, two security filters are arranged, the security filter is used as a main filter and a standby filter, the solution is returned to the original electric desalting system after being filtered by the security filter to realize forced regeneration cleaning, the normal desalting function of EDI is ensured, and safety guarantee is provided for stable operation water of the unit.

Claims (2)

1. The EDI regeneration cleaning system is characterized in that: the device comprises a cleaning box, a regenerative circulating water pump and two security filters, wherein a liquid outlet pipe of the cleaning box is respectively communicated with inlets of the two security filters, and liquid outlet pipes of the two security filters are communicated to a main discharge pipe;

the bottom outlet of the cleaning box is communicated with a circulating pipeline which is communicated to the liquid outlet pipe;

the recycling pipeline is provided with the regeneration recycling water pump.

2. The EDI regenerative cleaning system according to claim 1, wherein: and valves are respectively arranged on the circulating pipeline and the liquid outlet pipe.
