Description
Technical field
The utility model relates to a kind of porous ammonium nitrate production technique vapor recovery and utilizes system, belongs to chemical technology field.
Background technology
Energy consumption index is the important control index of chemical industry, directly concerns company interest and national energy-saving and reduces discharging requirement.Porous ammonium nitrate prior art design is one section of evaporation, 147.5 ℃ of technique vapor pressure 0.35MPa, temperature.If one section of whole adopting process steam of evaporation, ammonium nitrate solution concentration can not reach 96% of its design, and maximum concentration only has 93%, and therefore one section of evaporation is pressed live steam in can only all using, technique steam cannot be recycled, and needs to consume a large amount of recycled water cooling process steams.Porous ammonium nitrate produce still do not have enterprise can in all recycle with technique steam.
Energy-saving and cost-reducing for a nearly step, the recycling that improves technique steam, researchs and develops this technique vapor recovery and utilizes system so that porous ammonium nitrate in producing in and process steam all reclaimed.
Utility model content
The purpose of this utility model is to develop a kind of porous ammonium nitrate production technique vapor recovery and utilizes system, in during porous ammonium nitrate is produced, all reclaims with technique steam.To achieve these goals, the technical solution of the utility model is as follows:
Porous ammonium nitrate production technique vapor recovery is utilized a system, it is characterized in that comprising successively the tubular reactor that connects, reactor separator, treating column, one section of vaporizer flash tank, one section of evaporator heat exchanger, one section of vaporizer separator, 96% solution tank, flash evaporator, header tank, prilling tower.
In an embodiment of the present utility model, during described one section of evaporating heat exchanger is all used and technique steam as thermal source, the neutralization reaction heat producing in porous ammonium nitrate production process is all recycled, and ton ammonium nitrate can be saved the about 18t of recirculated water for process for cooling steam.
?in an embodiment of the present utility model, described flash evaporator shell side thermal source changes 0.6～0.8MPa, 164～175 ℃ of grade steam into by intrinsic 1.0～1.4MPa, 183～198 ℃ of grade steam.
The utility model is by changing one section of evaporation of traditional porous ammonium nitrate Production Flow Chart into dual circulation, will in and technique steam all reclaim as one section of evaporation thermal source, during traditional porous ammonium nitrate is produced idle unit---flash evaporator is transformed, select inferior grade steam to heat, realized porous ammonium nitrate produce in and the whole recovery of process steam, and reduced the consumption of live steam and water coolant, for domestic first in the ammonium nitrate production of hole, technique steam is all recycled, live steam consumption is also minimum.Through the operation more than 2 years, prove, energy-saving effect highly significant, normally produces steam consumption and is about originally 1/3, and ton ammonium nitrate can steam saving 0.22t, and dosis neutralisata is larger, and energy-saving effect is more obvious.
Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present utility model.
