Embodiment
As shown in Figure 1, the interchanger of a kind of low bromine Resins, epoxy reactor of the present utility model, it comprises front cool condenser 1 and rear cool condenser 2, and described the first housing 11, the second housing 21 equal right-to-left ends are obliquely installed from high to low, so that recirculated water and refrigerated water flow, make that itself and acetone steam are more abundant to be contacted.Described front cool condenser 1 comprises the first housing 11 and the first tube sheet 111, some heat transfer tubes 10 have been horizontally disposed with between the first tube sheet 111 in described the first housing 11, be vertically installed with traverse baffle 19 between described the first housing 11 interior described the first tube sheets 111, improve the shell side flow velocity with this, increase fluid shell side path, finally strengthen heat transfer effect and also play the effect of supporting heat transfer tube.Described front cool condenser 1 is positioned at described the first housing 11 top and bottom and is provided with expansion joint 18, because be that heat and mass is carried out in the lower refrigerated water heat exchange of high temperature gas phase and temperature lower recirculated water, temperature in the condenser, therefore have the phenomenon of expanding with heat and contract with cold, the described expansion joint 18 of setting strengthens interchanger heat expansion shrinkage ability to bear.One side upper end of described the first housing 11 is provided with gas phase import 12, enters for acetone steam.Lower end part at homonymy is provided with water-in 13 in described the first tube sheet 111 inboards, and recirculated water enters from this water-in 13.In these the first tube sheet 111 arranged outside gaseous phase outlet 14 is arranged at described the first housing 11 offside upper-end part of drivings, for carrying out acetone steam output after the heat exchange with recirculated water.The recirculated water that obtains heat with the acetone steam heat exchange is then exported from the water outlet 15 that is positioned at these the first tube sheet 111 inboards.The first tube sheet 111 inside bottom of described front cool condenser 1 are provided with leakage fluid dram 17.Described the first housing 11 bottoms and this gaseous phase outlet 14 opposite positions are provided with condensate outlet 16, and acetone steam is through changing the just from then on mouthful discharge of thermogenetic phlegma with recirculated water.
Described rear cool condenser 2 comprises the second housing 21 and the second tube sheet 211, has been horizontally disposed with some heat transfer tubes 20 between the second tube sheet 211 in described the second housing 21, all is vertically installed with traverse baffle 29 between described the second housing 21 the interior the described the 2 211.Described rear cool condenser 2 is positioned at described the second housing 21 upper ends, the lower end is provided with expansion joint 28.One termination of described the second housing 21 is horizontally installed with a dividing plate 30 between described the second tube sheet 211, because the second housing 21 upper and lower end parts will arrange respectively refrigerated water import and outlet in this section space.Corresponding described the second housing 21 bottoms that are positioned at described dividing plate 30 positions are provided with refrigerated water import 23, and the upper end is provided with chilled water outlet 25, and described the second housing 21 homonymy upper-end part of drivings are provided with gas phase import 22 in described the second tube sheet 211 inboards.Described the second housing 21 offside lower end parts are provided with condensate outlet 26 in this tube sheet inboard.Described the second housing 21 offside upper-end part of drivings are provided with drain 24 in these tube sheet both sides, are used for draining described the second housing 21 interior a small amount of gases, because almost all reflux in described condenser 2 at this stage acetone steam, therefore gaseous phase outlet are set no longer.The second tube sheet 211 inside bottom of described rear cool condenser 2 are provided with discharging hole 31, and it act as the foreign material in the emptying pipeline.
Utilize the lower boiling of acetone, make acetone through twice on interchanger step by step cooling band walk heat, again its overwhelming majority is passed back into reactor.In front cool condenser, amount of heat is taken away in recirculated water and acetone heat exchange, allows a large amount of acetone reflux at this.This moment, acetone steam refluxed in tube side, and recirculated water refluxes in shell side; In rear cool condenser, make refrigerated water and acetone heat exchange, deep condensation allows residue acetone almost all in this backflow, and acetone steam refluxes in shell side, and refrigerated water refluxes in tube side.By B-grade condensation, the acetone of cleaning is recovered use, has realized that the resource recycling has also reduced environmental pollution.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
