Technical field
The present invention relates to the brine waste desalting plant, particularly a kind of brine waste is handled with the overcritical salt demineralizer of analysing.
Background technology
The organic compound supercritical water treatment technology is by supercritical water oxidation is technological, supercritical water partial oxidation is technological and the technological three technology of supercritical water gasification constitutes.
Supercritical water oxidation technology (Supercritical Water Oxidation is called for short SCWO) is mainly used in the processing of organic waste, have speed of response fast, handle thoroughly non-secondary pollution and meet totally enclosed requirement.Because supercritical water has special nature, as: a little less than the hydrogen bond, be similar to the specific inductivity of non-polar organic solvent; High spread coefficient; LV etc., make its can with non-polar molecule (as air, oxygen and) miscible with arbitrary proportion, phase interface disappears; And then the elimination resistance to mass transfer, make organism and oxygen that oxidizing reaction take place rapidly in supercritical water and decompose.
Supercritical water partial oxidation technology (Supercritical Water Partial Oxidation; Be called for short SWPO); The amount of the oxygenant that finger provides in reaction is lower than the needed amount of organism complete oxidation; Can produce hydrogen again by the oxygenolysis hardly degraded organic substance, realize the harmless treatment and the recycling of organic pollutant simultaneously, also effectively suppress the coal-tar middle oil generation of gasification reaction.
Supercritical water gasification technology (Supercritical Water Gasification is called for short SCWG) is that organism decomposes gasification in the supercritical water environment of non-oxidation agent, and generates with hydrogen the process of the inflammable gas that is the master.This process not only speed of response fast, can recovery system heat energy and the generation high pressure gas being convenient to carry.
But inorganic salt are dissolved in supercritical water hardly; Therefore, when handling high saliferous material, existing desalting plant is because easy system jams that causes of salt sedimentation and heat transfer deterioration with the supercritical water treatment technology; Increase the corrosion of salt pair follow-up system simultaneously, thereby improved system's cost of investment.
Summary of the invention
In the defective or the deficiency that exist aspect the desalination, the object of the present invention is to provide a kind of brine waste to handle to existing super critical water treatment system with the overcritical salt demineralizer of analysing.
In order to achieve the above object, the present invention takes following technical scheme to be achieved:
A kind of brine waste is handled with the overcritical salt demineralizer of analysing; Comprise straight barrel, be arranged on the straight barrel upper end end cap, be arranged on the conical head of straight barrel bottom; It is characterized in that the barrel of straight barrel is divided into inside and outside two-layer, wall of the outer-rotor is inboard forms annular lacuna with the inner tube wall outside; The inboard formation of inner tube wall inner chamber is provided with desalination fluid outlet communication with cavity on end cap; In the wall of the outer-rotor outer upper saliferous fluid intake is set and is communicated with annular lacuna; Setting rotates through filter cylinder in the inner tube wall lower end; Scraper is arranged rotating through the filter cylinder arranged outside, the solid salt outlet is set, be provided with support at the straight barrel internal upper part rotating shaft that runs through the straight barrel axle center is fixed in the conical head bottom; The connection of rotating shaft lower end rotates through filter cylinder, and rotating shaft upper end external part cover is connected with speed reduction unit through the magnetic force envelope.
In the such scheme, said end cap is provided with tensimeter and relief valve connection.Back flushing inlet communication with cavity also can be set on the said end cap.Said filter cylinder and the inner tube wall of rotating through is provided with dynamic seal between axially.Said rotating shaft upper end is stretched out the part that end cap is connected with speed reduction unit and is provided with watercooling jacket.The said filter cylinder that rotates through adopts high temperature anticorrosive metal wedgewise structure.
The advantage that the present invention analyses the salt demineralizer is; Be arranged between close-to-critical range to the supercritical region of super critical water treatment system; Utilize inorganic salt to have higher solubleness, and, make inorganic salt separate out and remove at supercritical region in the insoluble,practically characteristics of supercritical region at close-to-critical range.Treat the subcritical fluids of heating and carry out water conservancy diversion and separate the fluid before and after the desalination through inside and outside barrel is set; Employing rotates through filter cylinder and cooperates with scraper; The inorganic salt of separating out filtered remove, can effectively prevent inorganic salt in system deposition and to the corrosion of follow-up system.
