Solution regeneration for scheme I, II all is under condition of normal pressure, i.e. non-boiling regeneration and boiling regeneration associating under the normal pressure realizes two-effect evaporation.Also can realize multiple-effect evaporation.
Figure 20 is that solution directly contacts (not conducting heat by partition) heating principle figure with flame, on housing 39 tops, lay a burner 44 that sprays downwards, at housing bottom, lay a solution nozzle 41 that upwards sprays, under certain pressure, weak solution 47 forms the jet 42 that upwards sprays by nozzle 41, and air and combustion gas form the torch 43 of downward injection, both move toward one another by burner, form percussion flow, liquid jet 42 is with torch 43 parcels, and weak solution is concentrated, and flows into housing bottom solution tank 40, concentrated solution flows out from outlet at bottom 45, and the steam of evaporation and flue gas are discharged from housing upper air vent 46.
Because the direct radiation effects of flame, heat and mass has been strengthened in interpenetrating and mixing of solution jet and flue gas; Jet disperses solution, has increased the heat and mass area; The liquid jet that last spray is fallen and torch of spraying out down and the move toward one another of the two, help to increase the action time of the two, because above-mentioned factor, than the indirect method, the capacity usage ratio height, the solution regeneration effect strengthens, and has reduced indirect heating apparatus, thereby the thermic load that has increased unit are reduces the weight and the volume of whole heater.
