Description
Technical field
The present invention relates to a kind of condensed water in high temperature oil removing process, belong to Water warfare field.
Background technology
Chemical plant and thermal power plant many employings vapours become after power consumption and heat exchange as heat power, vapours
Condensed water, its heat accounts for the 20%-30% of steam gross energy.This is a part of excellent desalted water resource, but the most often contains
Having the oil of trace, general oil content is between 1～150/L, far above boiler feedwater oil-containing quality standard, and therefore can not be direct
Utilize as boiler feedwater.The difference of device and the time of operation causes condensing oil-containing kind and quantity phase not to the utmost in water
With, different ways of recycling causes the oily existence condensing in water different, adds that the temperature condensing water is higher to high temperature
The intractability condensing water is very big.According to investigations, factory of domestic each great oil refining is owing to being limited by existing oily water separation technique, it is impossible to
Effectively the micro oil condensed in water is removed, the most it thoroughly do not processed and recycle, except small part is used
Make heating installation water, the supplementary water major part of recirculated water is emitted in vain, and this low value utilizes and not only causes valuable water resource
Significant wastage, pollute environment, also reduce Business Economic Benefit.And this way also brings series of problems, such as:
1) oil-containing condenses water and can not recycle, and power station boiler is accomplished by supplementing substantial amounts of demineralized water, causes water resource and the energy
A large amount of wastes；2) owing to heating, heating system life-time service oil-containing condensation water are as supplementary water, in water, oil stain takes care of the pence, attached
At inner surface of pipeline, have impact on the heat transfer efficiency of heat power equipment；3) oil-containing condensation water is unprocessed, discharges on the spot, slightly dirty
Contaminate environment.
CN101092258A(2007.12.26) a kind of method using processing high temperature condensed water by integration technique of membrane is disclosed,
Condensed water in high temperature first passes through microfiltration or ultrafiltration membrance filter retains major part impurity and greasy dirt, passes through ion exchange resin bed the most again
Adsorption ionic impurity.The method aquifer yield is little；The anti-masses hit of filter membrane is poor, easily causes the seepage of institute's adsorbent, makes
Become secondary pollution.
Summary of the invention
A kind of condensed water in high temperature oil removing process of offer is provided.Compared with prior art, present invention tool
