Background technology
Existing pharmaceutical industry injection water production device mainly uses the mode of multi-effect distilling to produce, and main flow equipment is
Six effect distillation machines, basic structure is made up of vaporizer, preheater and condenser, is tubular heat exchanger,
Wherein vaporizer is that steam (gaseous state) carries out heat exchange with purified water (liquid), is that steam is cold outside heat exchanger
Solidifying phase transition process, be the phase transition process of purified water evaporation in pipe, because 1KG water for cooling 1 DEG C is discharged
Heat is 4200J, and 1KG steam is condensed into the heat that liquid (this process temperature does not changes) is discharged
Amount is 2164700J (by 133 DEG C of calculating), is the former 515 times, so required for purified water evaporation
Heat mostlys come from the condensation phase transition process of steam.
In prior art, vaporizer and preheater use direct-connected mode, install fixed joint between adpting flange
Stream plate, to reach to keep evaporator condensation pressure, make full use of the purpose of steam latent heat.The advantage of which
It is: make simple, save space.Shortcoming is: cannot ensure accurately to control, when steam pressure fluctuates, or
During the fluctuation of purified water flow of inlet water, steam condensation number changes, and between vaporizer and preheater, pressure differential is sent out simultaneously
Changing, when vaporizer be condensed water logging do not have time, heat exchange area reduce, heat transfer effect decline；When steam from
When choke block between preheater and vaporizer leaks, steam thermal energy is underused, under heat transfer effect is same
Fall.Under the situation that steam pressure is stable, the multi-effect water distillator of conventionally form often produces 1000KG injection
The industrial steam of water mean consumption is in the range of 230KG-250KG.
