Description
Technical field
The present invention relates to pharmacy technical field of auxiliary equipment, particularly a kind of high energy-saving type thermocompression distiller.
Background technology
At present, the thermocompression distiller produced both at home and abroad has two kinds, and one kind is vertical type evaporator type, and another kind is horizontal
Evaporator type, its operation principle are all to employ vapour compression machine (also referred to as hot press), convert electric energy to heat energy and are evaporated
Operation, only feed water is heated using working steam.Although energy-saving effect is in the special equipment of current production distilled water
Best, still, still suffer from problems with：
First, containing substantial amounts of heat in condensate caused by working steam, do not recycled effectively, but in vain
White throws away, and the heat wasted can be seen that by following explanation：
By taking the thermocompression distiller of 10 tons of production capacity as an example, 10,000kg distilled water is produced per hour, must be consumed
1200kg working steams, that is, 1200kg condensed waters are produced, after testing, the discharge temperature of condensed water is 120-125 DEG C.
Condensate temperature takes t1=120 DEG C, the charging coolant-temperature gage of distillation machine is generally 15-25 DEG C, takes centre
Value T1=20 DEG C.If with charging water cooling condensed water, then, by charging coolant-temperature gage T135 can be down to by condensate temperature by knowing
Below DEG C, 35 DEG C are taken.Specific heat at constant pressure according to water is approximately cp=1kcal/ (kg DEG C), it is known that condensed water is obtained by feed water
The heat taken is Q=1200 × cp×(t1- 35)=102000kcal.During according to thermocompression distiller normal operation, charging
The working steam meter pressure 2kgf/cm of water heater2, look into saturated vapor physical property table and obtain, the latent heat of vaporization of working steam is r=
518.1kcal/kg, heat Q is converted into working steam amount
W=Q/r=196.9kg.
That is, often produce 10 tons of distilled water just in vain thrown away working steam 196.9kg.
If recycle these working steams, then, energy-saving efficiency can improve
(196.9/1200) × 100%=16.4%.
Second, heat recovery is more difficult：Although as you know there is larger thermal losses, to carry out above-mentioned
There is more difficulty in the recovery of heat, its main cause is：
Want to be truly realized and can effectively reclaim above-mentioned heat, must just solve not coagulate caused by after working steam condenses
The discharge problem of gas, otherwise (it is small that the distillation machine for having many pharmacy corporations runs 16 daily during heater long time continuous working
When more than, or even also daily 24 hours operation), the fixed gas in working steam heating operation room will roll up,
It will also be thickeied in the fixed gas film layer that heat transfer interface is formed, the thermal resistance of working steam and heat transfer interface is increased, heated
The heat transfer coefficient of device also will drastically decline, and cause the production capacity of complete machine drastically to decline or even can not normal operation.
When working steam condensate heat does not reclaim, because condensate discharge pipe is shorter and it is usually from top to bottom or horizontal to be
Flowing directly under throw away in well and (therefore lower well mouth substantial amounts of steam of emerging can be frequently seen in pharmacy corporation and is showed
As), therefore will not produce effective water seal phenomenon during condensate flowing, i.e. pipeline is not sealed completely by condensate, is just had in pipeline
A small amount of vapour (gas) body flowing space, fixed gas can emit with vapour (gas) the body flowing space.
When the heat of working steam condensate is reclaimed, condensate carries out heat again after needing to be collected into heat exchanger
Recovery, i.e. condensate enter working steam condensate heat by the pipeline between heater and heat recoverer (being exactly heat exchanger) and returned
Receive device, condensate line length and also tedge section, after especially condensate enters heat recoverer, because heat recoverer only uses
, could maximally effective carry out heat recovery during reverse-flow horizontal tubular heat exchanger.Condensate (is required according to GMP, managed in shell fluid flow
Journey is compared with shell side sanitary cleaning therefore walks raw water), shell side is equipped with deflection plate, when lateral flow of the condensate full of shell side generation heat exchanger tube
When and under the process conditions of countercurrent heat-transfer, could have best heat exchange efficiency.Otherwise, because " water → water " heat transfer effect compared with
Difference, the maximum recovery purpose of heat in condensate is not just reached at all.In this case, condensate will necessarily produce in flow process
Raw effective water seal, make fixed gas without can by gas passage can not discharge.Above reason may be exactly, both domestic and external
Thermocompression distiller is so far also without the heat recovery that can accomplish working steam condensate.
Third, the operating efficiency of hot press reduces：Due to the structure of traditional demister (steam-water separator), cause to steam
The pure steam venthole for sending out device is too high (at the top of evaporator) so that the pure steam outlet of evaporator and the pure steam of hot press
Connecting line between entrance it is oversize (be 4m or so, the hot pressing distillation machine of especially horizontal-type evaporator is longer, about 5m with
On).Pure steam in normal work in evaporator is to be drawn into hot press pressurizeed, heated up by hot press, Zhi Houzai
Evaporation tube group shell side is sent into by hot press operation is evaporated to the raw water in tube side.Because pure steam enters the pipeline of hot press
It is long, so pure steam flow resistance increases, the inhalation power of hot press is also increased therewith, the work done during compression of hot press but subtracts therewith
It is small, cause the power consumption of the hot press under specified production capacity to increase, that is, waste the energy.
