Description
Technical field
The present invention relates to concentration technology apparatus field, espespecially a kind of plate type heat exchanger concentration systems and concentration technology thereof.
Background technology
At existing evaporative crystallization, evaporation concentration device, three kinds of main technology are had to realize at present.
1. effect technique more than (MEE): in multi-effect evaporating device, initial steam heating the first effect the steam produced does not enters cold
Condenser, but as second effect add thermal medium be able to again with.So initial steam can be consumed and effectively reduce about 50%.
Reuse this principle, initial steam consumption can be reduced further.The maximum heating temperature of the first effect and the minimum boiling of last effect
Point temperature defines total temperature difference, is distributed in each effect.As a result, often the effect temperature difference increases with effect number and reduces.So for reaching to specify
Evaporation rate must increase heating surface (area) (HS.Preresearch estimates shows, for the effective heating surface (area) (HS of institute with the effect proportional increase of number,
So, while steam saving gradually decreases, investment cost dramatically increases.
2. during the recompression of thermodynamic steam recompression (TVR): thermodynamic steam, according to heat pump principle, from boiling-house
Steam is compressed to the elevated pressures of heating chamber；I.e. energy is added on steam.Due to corresponding with heating chamber pressure saturated
Vapor (steam) temperature is higher so that steam can be used further to heating.Steam jet ejector is used for this.They are former according to ejector pump
Reason operates, and does not has movable part, designs simple and effective, and can ensure that the highest functional reliability.Use a thermodynamic steam
Compressor has identical saving steam/energy-saving effect with increasing 1st effective evaporator.The operation of thermodynamic steam compressor needs one
The initial steam of determined number, the most so-called power steam.These power steams must be communicated to next effect, or is sent to condensation
Device is as residue vapor.The energy equivalence that the dump energy being included in residue vapor is about provided with power steam.
3. mechanical vapor recompression technology (MVR): during function of mechanical steam recompression, will evaporation by mechanically operated compressor
The both vapor compression that device steams is to elevated pressures.Therefore the machine that recompresses also serves as heat pump and carrys out work, increases energy to steam.With with following

Carry out work, therefore special compressing hot pump can be regarded as.Both vapor compression and subsequently add vapours condensation after, condensed fluid from
Open cycle.Add vapours (side of heat) to be separated by the heat exchange surface of vaporizer with indirect steam (cold side).Open
Formula compressing hot pump shows with the contrast of closed compressing hot pump: the evaporator surface in open systems substantially instead of closing
The function of process fluid expansion valve in system.By using relatively little of energy, i.e. compressor leaf in the case of compressing hot pump
The mechanical energy of wheel, energy is added into technique and adds in thermal medium and enter circulation continuously.In the case, it is not necessary to primary steam is made
For adding thermal medium.
Three of the above evaporating and concentrating process is respectively arranged with advantage, but there is also deficiency: all use shell-and-tube heat exchanger (to include fall
