The utility model discloses concentrated water pump 2 realizes the high liquid level of concentrated water tank from opening, the function of low liquid level stop automatically through converter 4, reaches energy saving and emission reduction's purpose.

Description

Reverse osmosis concentrated water recovery device

Technical Field

The utility model relates to a reverse osmosis dense water recovery unit.

Background

In the past, during reverse osmosis operation, concentrated water is discharged to a sewage tank through a concentrated water discharge pipeline, the concentrated water is not fully utilized in the concentrated water treatment mode, the loss amount of the concentrated water is huge every year, and the concentrated water is completely discharged outside, so that the resource waste is caused.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a dense water recovery unit of reverse osmosis, the whole recycle of dense water that produces when with reverse osmosis operation reaches energy saving and emission reduction's purpose. The technical scheme of the utility model is that: the utility model provides a dense water recovery unit of reverse osmosis, by dense water tank (1), dense water pump (2), dense water recovery pipeline (3) and converter (4) are constituteed, the dense water that the reverse osmosis operation produced gets into dense water tank (1) through dense water recovery pipeline (3), the tube coupling dense water pump (2) of dense water tank (1) bottom, dense water pump (2) are carried to softening system (5) through the pipeline, dense water tank (1) liquid level signal feedback to converter (4), converter (4) control dense water pump (2) are from starting, the low liquid level self-stop at dense water tank (1) high liquid level.

The utility model discloses a theory of operation:

the utility model relates to a collect to dense water tank through dense water discharge pipeline, dense water tank liquid level feedback to converter, the converter is according to opening of dense water tank liquid level control dense water pump and stops, retrieves dense water to softening system and softens the processing, reaches energy saving and emission reduction's purpose.

The utility model discloses technological effect:

the utility model discloses the dense water that produces when increasing reverse osmosis dense water recovery unit and moving reverse osmosis collects to dense water tank through dense water discharge pipeline, retrieves to softening the system through dense water pump again and softens the processing, and the dense water just can whole recycle like this, reaches energy saving and emission reduction's purpose. This device accessible converter is according to opening of high, the low automatic control concentrated water pump of concentrated water tank liquid level and stops, retrieves to softening the room through the concentrated water pump is whole with the concentrated water and retrieves. After the reverse osmosis concentrated water recovery device is put into operation, 3 million cubic meters of concentrated water are recovered every year, and the cost of tap water is saved by about 14 million yuan.

Fig. 1 is a working principle diagram of the present invention.

Detailed Description

As shown in figure 1, a reverse osmosis concentrated water recovery unit, by concentrated water tank 1, concentrated water pump 2, concentrated water recovery pipeline 3 and converter 4 are constituteed, the concentrated water that the reverse osmosis operation produced gets into concentrated water tank 1 through concentrated water recovery pipeline 3, the tube coupling concentrated water pump 2 of concentrated water tank 1 bottom, concentrated water pump 2 passes through the pipeline and carries to softening system 5, 1 liquid level signal feedback of concentrated water tank is to converter 4, converter 4 control concentrated water pump 2 is at 1 high liquid level of concentrated water tank from starting, the low liquid level self-stop.

Claims (1)

1. A reverse osmosis concentrated water recovery device is characterized in that: by dense water tank (1), dense water pump (2), dense water recovery pipeline (3) and converter (4) are constituteed, dense water that the reverse osmosis operation produced gets into dense water tank (1) through dense water recovery pipeline (3), the tube coupling dense water pump (2) of dense water tank (1) bottom, dense water pump (2) are carried to softening system (5) through the pipeline, dense water tank (1) liquid level signal feeds back to converter (4), converter (4) control dense water pump (2) are from starting, the low liquid level is from stopping at dense water tank (1) high liquid level.
