The specific working process of the invention is as follows:
when the evaporator works, firstly, liquid is injected into the evaporation tray 10, then the power supply is started, the power supply heats the inside of the evaporation tray 10, as the temperature rises, the low-boiling-point liquid in the evaporation tray 10 evaporates, the evaporated gas moves upwards and pushes the turbine 14 to rotate, during the rotation of the turbine 14, the poke rod 18 positioned at the edge of the turbine 14 pushes the sealing block 26 at the bottom of the liquid leakage hole 13 to rotate, so that the sealing block 26 is separated from the bottom of the liquid leakage hole 13, the liquid in the liquid storage chamber flows down to one side of the evaporation tray 10, so that the position of the evaporation tray 10 where the liquid falls sinks downwards, when the force applied by the torsion spring on the poke rod 18 is smaller than the force applied by the first mounting plate 28 and the spring fixedly connected with the first mounting plate 28, at this time, the poke rod 18 bends and slides over the sealing block 26 and the first mounting plate 28, at this time, the sealing block 26 at this position seals the weep hole 13 again under the action of the spring, the poke rod 18 bypasses the first mounting plate 28 and the sealing block 26, rebounds under the action of the torsion spring again, and pokes the next sealing block 26 to move in the counterclockwise direction, and opens the next weep hole 13 to discharge, at this time, the liquid inside the liquid storage chamber falls to another position of the evaporation disk 10 through the weep hole 13, and makes the position of the evaporation disk 10 incline downward, similarly, when the turbine 14 continues to rotate, the poke rod 18 on the turbine 14 will poke the third sealing block 26 to move in the counterclockwise direction, and open the third weep hole 13 to make the liquid inside the third liquid storage chamber flow downward, so that the evaporation disk 10 directly below the third weep hole 13 sinks downward, and thus during the rotation of the turbine 14 by 180 degrees, the liquid storage chambers at different positions are intermittently fed, and different positions of the evaporation tray 10 sink and float, so that liquid in the evaporation tray 10 is spread at different positions in the evaporation tray 10 and contacts with different positions in the evaporation tray 10, the evaporation efficiency of the liquid in the evaporation tray 10 is improved, the lightness removing efficiency is improved, and evaporated gas moves upwards through the gas outlet holes 24 and enters the filling holes 8 in the filling plate 7; meanwhile, descending liquid is pumped into the interior of the spraying disc 4 through a water pump and is sprayed out from the spray head 6 at the bottom of the spraying disc 4; at the moment, the liquid is sprayed downwards in a mist shape and enters the filling holes 7 on the filling plate 7 for dispersion; the evaporated gas phase is in countercurrent contact with the descending liquid, during the contact of the two phases, the volatile (low boiling point) component in the descending liquid is continuously transferred to the gas phase, the difficult volatile (high boiling point) component in the gas phase is continuously transferred to the descending liquid, the concentration of the volatile component in the gas phase is higher as the gas phase is closer to the tower top, and the concentration of the difficult volatile component in the descending liquid is higher as the descending liquid is closer to the tower bottom, so that the purpose of component separation is achieved; when the turbine 14 rotates 180 degrees and continues to rotate, at this time, the poke rod 18 will push the push rod 15 located at the rear edge of the evaporation pan 10, so that the arc-shaped sealing plate 30 is separated from the feed opening at the edge of the evaporation pan 10, at this time, the liquid in the evaporation pan 10 from which the low boiling point components are removed enters the interior of the thermal insulation box body 2 from the feed opening, at the same time, the liquid sprayed from the spray head 6 directly falls into the interior of the evaporation pan 10 through the air outlet hole 24 after the lightness of the liquid is removed by the packing plate 7, so that the low boiling point components which are not removed in the falling liquid are evaporated again, the evaporated liquid enters the bottom of the thermal insulation box body 2 and finally flows out from the liquid outlet 31 for collection, and the low boiling point gas enters the position above the spray pan 4 through the light gas outlet 5, is condensed by the condensing plate 20 and falls on the surface of the spray pan 4, and finally, and finally collected;
according to the invention, three liquid storage chambers are adopted for intermittent blanking, so that the evaporation disc 10 is in a continuous oscillation state, liquid is fully contacted with the inner wall of the evaporation disc 10 in the evaporation disc 10, the heat in the evaporation disc 10 can be fully utilized, the heating effect and efficiency are improved, and when the turbine 14 rotates for 180 degrees and then continuously rotates, the poke rod 18 positioned at the edge of the turbine 14 opens the blanking port on the evaporation disc 10, so that the lightened liquid enters the bottom of the heat preservation box body 2 for collection, and the collection is convenient; simultaneously arc stock solution storehouse 9 is located the inside of insulation box 2, and the heat that is located evaporation dish 10 can spread the inside of arc stock solution storehouse 9 and then preheat the liquid of stock solution indoor portion, and then when preventing the inside heat of evaporation dish 10 outwards diffusion for heat energy storage is in the liquid of stock solution indoor portion, thereby reduces the energy consumption.
