A kind of atomization and vaporization device
Technical field
The utility model relates to a kind of waste evaporator plant, is mainly used in the atomization and vaporization tripping device of high concentrated organic wastewater and high-salt wastewater.
Background technology
Waste water vaporizer is for all kinds of high concentrated organic wastewater in industrial production and high-salt wastewater, based on the principle of evaporation concentration and crystallization, multiple-effect reduction vaporization is adopted to concentrate waste water, after salinity in concentrated solution is separated, dried recovered or burning disposal is carried out by salt receiver, water of condensation after evaporation is generally processed by follow-up biochemical treatment, can realize the standard of discharge of wastewater.In addition, the solid water that vaporizer is also widely used in containing solid waste water is separated, and the water vapour evaporated reclaims through the condensation of postorder condenser, and solid materials then major sedimentary, at the bottom of evaporating pot, is done correspondingly to manage elsewhere.In order to improve the vaporization efficiency of solvent in waste water in prior art, waste water first need be atomized in evaporating pot, then pass into high-temperature steam again and realize waste water vaporization, blemish in an otherwise perfect thing be, while adopting this atomization and vaporization mode to carry out solid-liquid separation, because atomization process is at tank body top, causes upflowing vapor to take away the atomization stoste of part without evaporation, and cause the incomplete defect of solid-liquid separation.
Utility model content
Technical problem to be solved in the utility model provides a kind of atomization and vaporization device for above-mentioned prior art, and the waste water that effectively can overcome atomization is mixed in the water steaming of outer row, improves the effect of solid-liquid separation.
The technical scheme in the invention for solving the above technical problem is: a kind of atomization and vaporization device, comprise evaporating pot and condenser, described evaporating pot is provided with waste water access tube, described evaporating pot inner chamber top is atomization chamber, bottom is concentrated sap cavity, lift line is provided with between described atomization chamber and concentrated sap cavity, close in evaporating pot above concentrated sap cavity and be provided with heat exchange pipe, described heat exchange pipe steam-out (SO) thermal source, described atomization chamber top is provided with water eliminator near the vapour outlet of evaporating pot, water eliminator is positioned at above atomizing nozzle, described water eliminator has some pieces of compact package to form, vertical setting, steam data feedback channel is formed between adjacent described water eliminator, described water eliminator surface is in ripple type.
Preferably, described lift line is connected with recycle pump.
Compared with prior art, the utility model has the advantage of: the atomization and vaporization device of said structure effectively can prevent the atomization material in atomization chamber to be mixed in up steam while carrying out atomization and vaporization, and cause the defect that in condensed Ethylene recov below, foreign matter content is not up to standard, improve solid-liquid separation efficiency.

Fig. 2 is the structural representation of water-stop sheet in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, atomization and vaporization device in the present embodiment, comprise evaporating pot 1 and condenser 2, described evaporating pot 1 is provided with waste water access tube 4, described evaporating pot 1 inner chamber top is atomization chamber, bottom is concentrated sap cavity, be provided with lift line 3 between described atomization chamber and concentrated sap cavity, described lift line 3 is connected with recycle pump 6, there is concentrated solution recovery tube 5 in lift line 3 top set.The upper end outlet of described lift line is provided with atomizing nozzle 9, close in evaporating pot 1 above concentrated sap cavity and be provided with heat exchange pipe 7, described heat exchange pipe 7 steam-out (SO) thermal source, described atomization chamber top is provided with water eliminator 8 near the vapour outlet of evaporating pot, water eliminator 8 is positioned at described atomizing nozzle more than 9, described water eliminator 8 is formed by the some pieces of vertical close-packed arrays of metal material, forms steam data feedback channel between adjacent described water eliminator 8, and described water eliminator 8 surface is in ripple type.
The atomization and vaporization device of said structure can overcome the defect that in prior art, in Ethylene recov, foreign matter content is higher, improves solid-liquid separation efficiency, and structure is simple, and it is convenient to realize.
In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
