Abstract

A concentrated water recovering system comprises a concentrated water recovering tank, a concentrated water high-pressure pump and a reverse osmosis device which are connected in sequence through a pipeline; and a scale inhibitor adding device for preventing concentrated water from scaling and a pH adjusting device for adjusting the pH value of the concentrated water are arranged between the concentrated water recovering tank and the concentrated water high-pressure pump. After recovering and reprocessing concentrated water, the concentrated water recovering system can produce water which meets the use requirements and can be reused, and is recovered into a raw water tank or is used as production water. Therefore, the water production efficiency of a purified water production system is improved, and water resource is saved.

Description

Dense water reclamation system

Technical field

The utility model relates to the dense water reclamation system in a kind of pure water production process.

Background technology

It is comparatively general that reverse osmosis unit is used to produce pure water, it has the water quality treatment wide ranges, it is good to produce water water quality, characteristics such as environmental protection, but because reverse osmosis unit is along with the carrying out of demineralising process, influenced by multiple factors such as dense polarization of reverse osmosis face and osmotic pressure, determined the current operation scheme of reverse osmosis unit to move for the cross-flow mode, thereby reverse osmosis unit need discharge a certain amount of dense water (be generally flooding quantity 25%), usually the reverse osmosis concentrated water salinity is very high, be about 4 times of former water, because meeting, it does not produce and the domestic water requirement, so conventional pure water Production Flow Chart is directly drained the dense water of this part as waste water, cause waste with water resources.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the deficiency that above-mentioned prior art exists, and a kind of dense water reclamation system is provided, and it has improved the producing water ratio of pure water production system, has saved water resources.

For solving the problems of the technologies described above, the utility model provides a kind of dense water reclamation system, comprise:, between dense water return water tank and dense water high-pressure pump, be provided with the PH setting device of the Scale inhibitors throwing device and the dense water ph value of adjustment of the dense water fouling of control with dense water return water tank, dense water high-pressure pump and the reverse osmosis unit that pipeline is linked in sequence.

Further, described dense water reclamation system also comprises a sterilizing unit, and it is arranged on the product water rising pipe place of described reverse osmosis unit.

Further, described dense water reclamation system also comprises an electrical control cubicles, and it electrically connects with described dense water return water tank, described dense water high-pressure pump, described reverse osmosis unit, described Scale inhibitors throwing device and described PH setting device respectively.

Further, be provided with the high voltage protective switch respectively, also be provided with tensimeter at the rising pipe place of described dense water high-pressure pump at the water inlet pipe and the rising pipe place of described dense water high-pressure pump.

Further, the product water rising pipe of described reverse osmosis unit is provided with rate of flow meter, tensimeter and conductivity table, is provided with tensimeter and rate of flow meter on the dense water rising pipe of described reverse osmosis unit.

Useful technique effect of the present utility model is: this dense water reclamation system with dense water reclaim handle again after, make that producing water satisfies the water requirement, can utilize again and be recycled to raw water box or as water of productive use.After dropping into dense water reclamation system, the total rate of recovery of pure water production system can be promoted to more than 90%, has improved producing water ratio greatly, has saved water resources; Simultaneously, remain waters such as the dense water in 10% left and right sides can clean as plant area, greening, finally reach the purpose of " zero " discharging.

Description of drawings

Fig. 1 is the structural representation of the dense water reclamation system of the utility model.

Embodiment

Fig. 1 is the structural representation of the dense water reclamation system of the utility model, as shown in the figure, this dense water reclamation system comprises: the dense water return water tank 1, dense water high-pressure pump 2 and the reverse osmosis unit 3 that are linked in sequence with pipeline, the rising pipe of dense water return water tank 1 links to each other with the water inlet pipe of dense water high-pressure pump 2, and the rising pipe of dense water high-pressure pump 2 links to each other with the water inlet pipe of reverse osmosis unit 3.

In order to reduce the settling in the reverse osmosis unit, this dense water reclamation system is provided with a Scale inhibitors throwing device 4 between dense water return water tank 1 and dense water high-pressure pump 2, scale deposition thing in its may command reverse osmosis unit, effectively control lime carbonate, Calucium Silicate powder and the fouling of calcium sulfate dirt, thus improve water production rate and produce quality.

Also be provided with a PH setting device 5 between dense water return water tank 1 and dense water high-pressure pump 2, it is in order to improve the pH value of intaking before the reverse osmosis unit 3, with a small amount of CO that exists in the dense water ₂Be converted into HCO ₃Deng negatively charged ion, be beneficial to it and in reverse osmosis unit 3, remove.

This dense water reclamation system also comprises an electrical control cubicles 6, it electrically connects with dense water return water tank 1, dense water high-pressure pump 2, reverse osmosis unit 3, Scale inhibitors throwing device 4 and PH setting device 5 respectively, moves by preset program to control dense water return water tank 1, dense water high-pressure pump 2, reverse osmosis unit 3, Scale inhibitors throwing device 4 and PH setting device 5.

Water inlet pipe and rising pipe place in dense water high-pressure pump 2 are provided with high voltage protective switch P S respectively, also are provided with tensimeter PI at the rising pipe place of dense water high-pressure pump 2.The product water rising pipe of reverse osmosis unit 3 is provided with rate of flow meter FI, tensimeter PI and conductivity table CI, is provided with tensimeter PI and rate of flow meter FI on the dense water rising pipe of reverse osmosis unit 3.

On the product water water pipe of reverse osmosis unit 3, also be provided with to producing the water germ-resistant sterilizing unit (not shown) that carries out disinfection, to satisfy the requirement of water.

The working process of this dense water reclamation system is as follows: the dense water of the RO in the pure water production system is pooled in the dense water return water tank 1, the water outlet of dense water collection box 1 is after adding Scale inhibitors and regulating pH value, squeeze in the reverse osmosis unit 3 through dense water high-pressure pump 2, to remove the salinity in the dense water, make water outlet reach former water water inlet requirement, water outlet enters sterilisation system to reach the water requirement, realizes dense Water reuse utilization, saves production cost.

The above only is a preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, and the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content have been done changes, and all is included in the protection domain of the present utility model.
