Management control in the process.
Background technique
Experimental analysis will often use high purity acid, and generate a large amount of spent acid, it is therefore desirable to will be in mixing acid pickle
Acid slow evaporation under sub- boiling state comes out, and condenses, is collected into the higher acid of purity, meets economical environment-protective.
Sour purifier is that heating keeps fluid temperature to evaporate lower than boiling temperature, then its acid vapor is condensed to prepare height
Pure water and high purity reagent are widely used in sample treatment and analysis.Ultrapure acid currently on the market is difficult since price is more expensive
Meet routine analysis demand, therefore purify the quality of optimization acid, is approach the most economically viable.It is that super clean laboratory is extracted
The competent assistant of high purity acid.

Personnel's carelessness, be easy to cause the generation of defect ware, and the serious equipment excess load that will lead to causes equipment burnout and laboratory fire
The great risk of calamity.
(3) for the liquid level of original acid solution, traditional solution judges liquid using the mode of range estimation liquid level tube
Position.Once personnel forget to estimate in time, it will the great risk for having dry combustion method even on fire.
(4) for the liquid level of high-purity acid solution, existing solution does not have any to detect and control measure automatically.Once liquid
Position is excessively high, and acid solution will overflow, and corrodes periphery object.
(5) traditional condensation process does not in real time monitor condensate temperature, easily causes and heat in gas condensation process
Liquid for condensation can not condense in time, can generate a large amount of strong acid steam, and recovery efficiency has very big discount.
(6) traditional heating method often just uses resistance heating, and not only power consumption is big, low to temperature adjusting sensitivity, cannot
Temperature in reacting furnace is adjusted in time, leads to the purity for influencing recycling acid solution.
(7) temperature controller of traditional solution is multi gear bit-type, rather than continuously adjustable type, can only probably be set
A fixed temperature value, can not accurately set.
(8) traditional solution is that temperature sensor is avoided to be corroded easily by high-temperature strong acid, temperature sensor peace
Mounted in container exterior, avoid contacting with strong acid, but such mounting means measurement be container outer wall temperature, can not reflect
The true temperature of acid solution, usual solution temperature will differ 5-20 DEG C with the temperature of container outer wall, and the measurement error of temperature is very big.
