Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
The present invention as shown in Figure 1, comprise dividing wall type condenser 1, dividing wall type condenser 1 one end is provided with dividing wall type condenser inlet 2, the other end is provided with the dividing wall type condenser-air outlet 3 of band reflux gas arm, dividing wall type condenser 1 body connects cooling media 4, cooling media 4 provides refrigerant to dividing wall type condenser 1, dividing wall type condenser-air outlet 3 with reflux gas arm connects reflux gas power set 5 and demister 6 respectively by pipeline, reflux gas power set 5 connect reflux gas entrance 7 by pipeline, reflux gas entrance 7 is positioned on dividing wall type condenser 1, make dividing wall type condenser 1 inside and export 3 with the dividing wall type condenser-air of band reflux gas arm, the pipeline that reflux gas entrance 7 connects forms a gas passage, reflux gas entrance 7 place is provided with adverse current blender 8, the bottom that the dividing wall type condenser-air of the band reflux gas arm of dividing wall type condenser 1 exports 3 one end is provided with dividing wall type condenser liquid outlet 9, demister leakage fluid dram 10 is provided with bottom demister 6, dividing wall type condenser liquid outlet 9 is connected total leakage fluid dram 11 with demister leakage fluid dram 10 by pipeline, demister 6 is provided with incoagulable gas outlet 12.
Reflux gas entrance 6 is between the 10%-90% of the vapor path length of dividing wall type condenser 1.
It is inner that gas to be condensed enters dividing wall type condenser 1 by condensing gas entrance 2, sent by cooling media 4 refrigerant cooling after in the gas passage of dividing wall type condenser 1, there is condensation, part congeal into bulky grain sedimentation or after being condensed in heat-transfer surface surface because Gravitational sliding is finally discharged from the dividing wall type condenser liquid outlet 9 of bottom.Due to the factor of Kelvin effect, a large amount of fine droplets is also there is in flowing gas, with dividing wall type condenser-air outlet 3 flowing of air-flow to the band reflux gas arm of dividing wall type condenser, now reflux gas power set 5 export 3 from the dividing wall type condenser-air of band reflux gas arm and extract portion gas, (gas of extraction is the 1%-60% of the gas gross to be condensed of input), be back to reflux gas entrance 7 place, fully to be mixed with the gas to be condensed condensing to uniform temperature by adverse current blender 8 and contact, for the gas be in the dividing wall type condenser 1 of hypersaturated state provides the nuclei of condensation, impel in the inner space of dividing wall type condenser 1 and also produce condensation rapidly, thus raising condensation effect.Containing more fine droplets in the gas of being discharged by dividing wall type condenser liquid outlet 9, finally discharged after the trapping of high efficiency demister 6 power by demister leakage fluid dram 10, remaining gas exports 12 by incoagulable gas and discharges.
Empirical tests, the reflux cycle system of the present invention by increasing, can lower 20-50% by the condensate concentration in the emission gases of existing condensing plant.Be particularly useful for the application scenario that in gas to be condensed, incoagulable gas content is greater than 20%.
