Description

It is a kind of it is flushable can chemical cleaning zero-emission energy-recuperation system
Technical field
The utility model is related to a kind of recovery system more particularly to it is a kind of it is flushable can chemical cleaning zero-emission energy return Receipts system.
Background technology
In order to utmostly reduce influence of the water process project to environment, wastewater zero discharge is Coal Chemical Industry in China, power plant, stone The important developing direction of the industries industry such as oiling work.It promulgates within 2005《Chinese water-saving technology policy outline》It is proposed that development is useless first Water " zero-emission " technology.It promulgates within 2007《National environmental protection Eleventh Five-Year Plan》It is more distinctly claimed in steel, electric power, change The key industrys such as work, coal promote cycling utilization of wastewater, strive for waste water and discharge less or zero-emission.
In process without drainage of waste water, reverse osmosis technology is the water technology risen in recent decades, has high desalination Rate, adapts to the features such as water quality range is wide at environmental protection, is widely used in the fields such as surface water reuse, sea water desalination and wastewater zero discharge.Instead Infiltration is by the dissolubility ion in aqueous solution, and organic matter etc. is selectively filtered, to play the works such as purification, separation With.Reverse osmosis produced water carries out reuse, and concentrated water is concentrated again by evaporator, FO etc., realizes energy-saving and emission-reduction truly.
The zero-emission RO films design rate of recovery commonly reaches 60% or more, or even is designed into 80%, greatly reduces concentrate Discharge capacity, to reduce the treating capacity of subsequent evaporation system.It is general waste water can be used enter level-one RO, RO concentrated water carry out RO again The concentrated water discharge of reverse-osmosis treated, concentrated water RO can be evaporated concentration.In this case, concentrated water RO water inlets total dissolved solidss (TDS) 20000mg/L or more generally is can reach, it is even higher, and high-pressure pump need to provide 30-60 kilograms of pressure, high-pressure pump Energy consumption is high, and energy recycle device can be used for the reverse osmosis part of zero-emission, greatly recycles the energy of concentrated water discharge, reduces high pressure The energy consumption of pump.
The prior art has the following disadvantages:Energy-recuperation system can't be a standard product in the market, lead to visitor Family is when carrying out system design, the only operation of consideration system, or omits or consider incomplete or protect reason to energy-recuperation system Solution is not thorough enough, causes energy regenerating product to be rinsed in Zero discharging system and will appear following situations with chemical clear water:
Wastewater zero discharge RO system RO films needs are periodically rinsed, and for flow depending on RO film quantity, this flow is all big In PX maximum stream flows.When being rinsed such as RO, the RO flushing doses needed are entered in RO systems, including RO films and energy regenerating product. That will cause energy regenerating product to be damaged because of super stream.
When RO film chemical cleanings, after washing down the particulate matters such as dirty class on RO films because of chemical cleaning, if not The processing means of any are carried out, this dirty class can enter energy regenerating product, lead to the main energy regenerating of card, or lead to energy regenerating The components such as product end cap, rotor are damaged by dirty class.
Energy-recuperation system accounts for relatively high cost of investment in systems, if damage, to engineering company and its terminal User is prodigious loss.
Under normal circumstances wastewater zero discharge energy regenerating product be not provided with it is flushable can chemically-cleaning device, it is one Product reduces the energy consumption of the preposition high-pressure pumps of RO for recycling the energy of RO concentrated waters.But this energy regenerating valuable product, Occupy 40% or so of RO system prices.Therefore owner particularly payes attention to the stable operation of this energy regenerating product.Good system fortune Row can be such that energy regenerating life of product reaches 20 years or so.Therefore one it is good it is flushable can chemical cleaning energy-recuperation system it is special It is unimportant.
The energy-recuperation system energy regenerating product of the prior art rinses in Zero discharging system and chemical clear water will appear Following situations:
1, wastewater zero discharge RO systems RO films needs are periodically rinsed, and flow is depending on RO film quantity, this flow is all More than PX maximum stream flows.When being rinsed such as RO, the RO flushing doses needed are entered in RO systems, including RO films and energy regenerating production Product.That will cause energy regenerating product to be damaged because of super stream.
2, when RO films chemical cleaning, after the particulate matters such as dirty class on RO films can be washed down because of chemical cleaning, if Without the processing means of a bit, this dirty class can enter energy regenerating product, lead to the main energy regenerating of card, or energy is caused to return The components such as product end cap, rotor are received to be damaged by dirty class.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found, one kind is new structural to rush Wash can chemical cleaning zero-emission energy-recuperation system, make it with more the utility value in industry.
