In order to keep the pressure difference of hyperbaric heating room 5 and vaporization chamber, valve is set between, when hyperbaric heating room 5 Pressure valve opening when reaching at or above 0.9;When the pressure of hyperbaric heating room 5 is lower than 0.6, valve is closed.In addition, in height The entrance of pressure heating room 5 also needs that check-valves is arranged, and avoids the desulfurization wastewater adverse current of high pressure.
Desulfurization wastewater in the present embodiment first can successively be softened, be concentrated, be obtained before entering hyperbaric heating room 5 To concentrated water, the concentrated water is connected to by waste water delivery pipe with hyperbaric heating room 5;The salt leg is sequentially communicated by salt slurry delivery pipe There are thickener and solid-liquid separating equipment.
Desulfurization wastewater can be introduced into wastewater collection pond before entering hyperbaric heating room 5 and be collected and homogenization, In view of the fluctuation of desulfurization waste water quality water, wastewater collection pond can be with design air blender, and waste water is through being sufficiently stirred in pond After homogeneous, lime is added, carries out preliminarily softened processing, forms the sediment of calcium sulfate, magnesium hydroxide, while magnesium hydroxide carries Silica forms co-precipitation, and mixed liquor enters clarifying basin, and the water outlet to clarifying basin continues supplement addition sodium hydroxide, to pH value Accurate adjustment is carried out, keeps magnesium hydrate precipitate more complete, adds sodium carbonate liquor, with the anti-shape of calcium ion remaining in clarifying basin water outlet At precipitation of calcium carbonate, filters out after solid particle takes clear liquid to carry out micro-filtration or ultrafiltration, depth scale removal and enter film concentration systems, wherein two Order reaction slot is respectively provided with mechanical stirring and pH value monitoring.Film concentration systems: it is main to realize that decrement treatment is concentrated in desulfurization wastewater, so that Wastewater flow rate into subsequent flue residue heat vaporising device is down to the 40% or less of raw water.
The effects of salt leg is arranged in 1 bottom of vaporization chamber, and salt leg plays collection salt, classification, washing, back dissolving soluble impurity, conveying, It is one of the quality for improving salt, the critical component for reducing system energy consumption.Salt leg provides speed appropriate and uniform for crystal salt Fluidization can be eluriated efficiently, cooled down, classified and be thickened.The crystal that the salt such as NaCl are constantly crystallized out in vaporization chamber 1, because of gravity Relationship moves downward, and gradually drops into salt leg from vaporization chamber 1, and washing lotion is entered by inlet tube from salt leg lower part, along leg wall It rises and the removal of the impurity such as organic matter, sylvite is improved into the quality of crystal salt with crystal salt countercurrent washing.Washing lotion is inversely transported with salt slurry Row has carried out heat exchange, reduces salt discharge temperature, reduces heat lost by brine.This technique uses gypsum seed method antiscale production technology, By the way that calcium sulfate crystal seed is added, heater fouling can be effectively reduced.
The salt slurry generated after evaporation drains into salt slurry tank from salt foot, is delivered to after thickener is thickened to 60% -70% by brine pump Centrifugal dehydration is carried out, centrifuge mother liquor returns to vaporization chamber 1.
It is entrained with drop when to avoid gas from being discharged or is evaporated salt, demister can be set in the vaporization chamber 1, it is described to remove Day with fog can make it is in the prior art any one, also may include: demister and the support frame 2 for supporting demister, institute Stating demister includes granular filler and for containing the carrying packet 3 of granular filler, and there are two the above uniform folds for the carrying packet 3 On support frame 2.
The present embodiment is in order to which while keeping the defogging effect of demister, the demister solved in existing vaporization chamber 1 is easy Blocking occurs or occurs to block difficult cleaning of problem, is provided with the structure, in which:
The partial size of granular filler can be determining according to the throughput of fog and the component of fog, in contrast, granular filler Partial size is smaller, defogging effect is better, but accordingly is also easier to block;The partial size of granular filler is bigger, is more not easy to plug, but demisting Effect can be relatively weaker, so the partial size of granular filler also needs those skilled in the art to select as needed.
Carrying packet 3 in the application should select material with certain flexibility, combine durability, can select fiber Net, thinner steel wire etc., so that carrying packet 3 is easy to happen deformation under the effect of external force: when the gap of granular filler is blocked Plug when influencing fog effect out, carrying packet 3 can be lifted, and carrying packet 3 can deformation occurs under gravity at this time, so that The relative position of granular filler changes, and generates friction in moving process between each other, can will block the substance in gap from It is separated on filler particles, so that demister be made to be dredged, dredging is convenient.And when placing it on support frame 2, Ke Yitong It crosses constantly to lift carrying packet 3 and put down, adjust the thickness of granular filler each section, convenient filling.
The support bearing packet 3 of support frame 2 in the application, as long as there is the gap on certain stability and support frame 2 Less than carrying packet 3 carrying packet 3 will not be slid from support frame 2.
