Description
Technical field
The utility model relates to a kind of pure water production unit, relates in particular to a kind of pure water production unit of high-recovery.
Background technology
Because pure water is widely used in numerous areas such as plating, electronics, electric power, biology, papermaking, pharmaceutical chemical industry, a large amount of pure water is produced by the pure water production unit of high-recovery.Yet, in water treatment procedure, contain the water of trace impurity in a large number from the direct discharge of concentrated water discharge Guan Zhongjing regular meeting, make that the repeating utilization factor of water is lower in the existing water treatment procedure, wasted a lot of water resourcess.Developing the pure water production unit of the high high-recovery of a kind of water use efficiency, is imperative with the conserve water resource.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of recovery utilization rate height, the effective pure water production unit of the high-recovery of conserve water resource are provided.
The purpose of this utility model is achieved in that a kind of pure water production unit of high-recovery, comprise the former water pretreatment system and the former water reverse osmosis system that are interconnected, described former water pretreatment system comprises former tank, raw water pump, sand-bed filter, carbon filter, softening agent and first secondary filter that is communicated with successively by pipeline; Described former water reverse osmosis system comprises middle tank, topping-up pump, plate-type heat exchanger, second secondary filter, high-pressure pump, former water reverse osmosis unit and the pure water case that is communicated with successively by pipeline; It is characterized in that: it also comprises dense water reclamation system, and described dense water reclamation system comprises the dense water tank that is communicated with successively by pipeline, dense water water pump, dense water sand-bed filter, dense water carbon filter, dense water softening apparatus, dense crystal's filter, dense water high-pressure pump and dense water reverse osmosis unit; Pipeline between dense water tank and the dense water water pump is connected with the container of dress flocculation agent, and dense water softening apparatus is connected with the container of adorning Scale inhibitors by volume pump with pipeline between dense crystal's filter; The water purification water outlet of dense water permeator is connected with the former tank of former water pretreatment system, and the water-in of dense water tank is connected with the dense water water outlet of described former water permeator.
The dense water water outlet of sand-bed filter, carbon filter and softening agent in the described former water pretreatment system is communicated with the water inlet of the dense water tank of described dense water reclamation system respectively.By recycling, improve the utilization ratio of whole water purification system water to the dense water in sand-bed filter, carbon filter and the softening agent in the former water pretreatment system.
Described first secondary filter, second secondary filter be with dense crystal's filter be that precision is the strainer of 5 μ m.
Advantage of the present utility model is: 1, the pure water production unit of high-recovery of the present utility model is by pre-treatment, reverse osmosis, and dense water reclaims three parts and forms.Preprocessing part: suspended substance, colloid, organism, part bacterium and chlorine residue during former water dewaters through sand filtration, charcoal elimination, remove most of calcium ions and magnesium ions in the water to prevent that surveying the scale formation that other material takes place surface deposition lime carbonate and prevention at the dense water of membrane module is that reverse osmosis unit provides into water condition through softening agent again; The reverse osmosis part: reverse osmosis unit is a topmost desalting plant in the former water treatment, and it has high desalination ability.Can remove impurity such as most colloid, ion, particulate in the water, water is carried out purification separation; Dense water recovery part: the dense water that produces through reverse osmosis isolation enters dense apparatus for recovering and carries out recycling, the utility model apparatus features be not only can the recycling reverse osmosis dense water, also can carry out recycling, can fundamentally improve the recovery utilization rate of water the dense water that produces in other pure water production processes.2, the pure water production unit of high-recovery of the present utility model dense water that original preparation is emitted is recycled once more, carries out secondary-cleaned, has not only improved the water purifying repeating utilization factor, has also avoided the waste of water resources; 3, the pure water production unit of high-recovery of the present utility model can be realized the serialization operation, and the recovery repeatedly of dense water quilt is purified again, and the reclamation rate of water is reached more than 85%; 4, the dense water of the utility model in not only can the recycling reverse osmosis unit also can carry out recycling to the dense water that other devices produce in the pure water production process, can fundamentally improve the recovery utilization rate of water.
