Description
Technical field
The utility model relates to a kind of heat utilization system, specifically a kind of methanol destilling tower gas phase potential, tower bottom are useless
Water condensation gas heat utilization system.
Background technique
When prepared by conventional methanol, need the methanol-water of 30% concentration carrying out purifying, collecting, wherein amount of heat is distilling
It is wasted in tower, condensing tower, causes serious thermal energy waste, resource utilization is low.
Summary of the invention
In view of the above-mentioned problems, to provide a kind of structure simple for the utility model, methanol-water effectively can be distilled into condensation and collected
Middle thermal energy makes full use of, the high methanol destilling tower gas phase potential of heat resource utilization rate, tower bottom waste water condensing gas heat utilization system
System.
The technical solution adopted in the utility model is：A kind of methanol destilling tower gas phase potential, tower bottom waste water condensing gas heat
Utilize system, it is characterised in that：Including methanol destilling tower, condensing tower, gas-liquid separator, collecting tank, reflux pump, reboiler, cold
Condenser, for feed inlet into methanol-water, methanol destilling tower bottom sidewall is equipped with wastewater outlet and again from the bottom to top in the middle part of methanol destilling tower
Boiling is answered back, and wastewater outlet and is boiled to answer back again and is separately connected the import and export of reboiler, and leakage fluid dram, leakage fluid dram is arranged in reboiler bottom
A hot journey through positive displacement pump connection condenser, methanol destilling tower top are sequentially connected condensing tower, gas-liquid separator, receipts through collecting pipe
Collect tank and connect methanol destilling tower top through reflux pump again, is socketed heat exchange sleeve on collecting pipe, methanol destilling tower upper portion side wall connects gas
Phase heat exchanger tube is connected to another hot journey of condenser after gas phase heat exchanger tube connection heat exchange sleeve and is followed by charging in the middle part of methanol destilling tower
Mouthful.
Tail gas discharging pipe is connect at the top of the gas-liquid separator.
The utility model methanol-water distills in a distillation column, and part methanol-water falls into tower bottom through wastewater outlet and again when starting
Boiling, which is answered back, is separately connected the import and export of reboiler, the gasification of methanol in reboiler, and waste water is arranged by the leakage fluid dram of reboiler bottom
Out, after gasification methanol enter methanol distillation the subsequent charging of column distillation methanol-water distilled, methanol steam through collecting pipe successively
It send condensing tower, gas-liquid separator, collecting tank to be condensed, gas-liquid separation and collect, in collecting pipe conveying, exchanged heat by gas phase
Part methanol steam is reduced the delivery temperature of methanol steam by pipe in Heat exchange jacekt intraductal heat exchange, and the methanol steam after heat absorption is through exchanging heat
Pipe absorbs reboiler leakage fluid dram by condenser and waste water heat is discharged, and returns again to methanol destilling tower and improves temperature in tower, absorption portion
Divide gas phase thermal energy and waste water thermal energy, improving heat resource utilization rate will be in collecting tank in order to improve methanol concentration in collecting tank
Methanol is through reflux pump methanol at reflux destilling tower, for improving successive concentrations, can effectively improve methanol preparation concentration.
