Abstract

The invention relates to a heat utilization system for methanol distillation-tower gas-phase latent energy and tower-bottom wastewater condensed gas. The heat utilization system comprises a methanol distillation tower, a condensing tower, a gas-liquid separator, a gathering tank, a reflux pump, a reboiler and a condenser, wherein methanol water enters a middle charging opening of the methanol distillation tower, a wastewater outlet and a reboiling return port are formed in the bottom side wall of the methanol distillation tower from bottom to top and are separately connected with an inlet andan outlet of the reboiler, a liquid outlet is formed in the bottom of the reboiler, the liquid outlet is connected with a heat course of the condenser through a liquid discharging pump, the top of themethanol distillation tower is sequentially connected with the condensing tower and the gas-liquid separator through a collecting pipe, the gathering tank is then connected to the upper part of the methanol distillation tower through the reflux pump, a heat exchange sleeve sleeves the collecting pipe, the side wall of the upper part of the methanol distillation tower is connected with a gas-phaseheat exchange tube, and the gas-phase heat exchange tube communicates with the heat exchange sleeve, then, is connected to another heat course of the condenser and then is connected with the middle charging opening of the methanol distillation tower.

Description

technical field [0001] The invention relates to a heat utilization system, in particular to a methanol distillation tower gas phase potential and tower bottom waste water condensed gas heat utilization system. Background technique [0002] When traditional methanol is prepared, it is necessary to purify and collect 30% methanol water, and a large amount of heat is wasted in distillation towers and condensation towers, resulting in serious waste of heat energy and low resource utilization. Contents of the invention [0003] In view of the above problems, the present invention provides a system with simple structure, which can effectively fully utilize the heat energy in methanol water distillation and condensation collection, and has a high utilization rate of heat energy resources. [0004] The technical scheme adopted in the present invention is: a methanol distillation tower gas phase potential, tower bottom waste water condensed gas heat utilization system, characterize...
