Description
Technical field
The utility model belongs to glacial acetic acid equipment for purifying technical field, particularly a kind of glacial acetic acid equipment for purifying.
Background technology
The molecular formula of acetic acid is C2H4O2, and boiling point is 118.1 degree, and Chinese is acetic acid, and nickname glacial acetic acid, belongs to
8.1st class corrosives.Thick acetic acid of the content produced with low pressure carbonylation method in 97-98% can just meet after purification
GB1903-2008《Food additives glacial acetic acid》Requirement.Thick acetic acid refers to containing formic acid, acetic anhydride, nonvolatile matter, chlorination
The acetic acid of the impurity such as thing, iron and heavy metal.Since the corrosivity of thick acetic acid is too strong, existing acetic acid purification device mainly uses stainless steel
Material is made, main to use distillation, rectifying, condense production technology by formic acid, acetic anhydride, nonvolatile matter, chloride, iron and a huge sum of money
The impurity removals such as category, are purified using the boiling point of acetic acid and impurity, condensation point difference.
Existing acetic acid purification device is to be flowed into acetic acid in distiller by balancer directly out of tank, and acetic acid is filling
Need to heat from the beginning when entering in purifying plant, therefore the heat consumed is more.
The content of the invention
The utility model is in view of the shortcomings of the prior art, provide a kind of glacial acetic acid equipment for purifying, this kind of glacial acetic acid equipment for purifying
Equipment volume can be reduced, while the heat consumed in purification process can be transmitted in acetic acid to be purified, so as to reduce
The heat that acetic acid purification is consumed.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of glacial acetic acid carries
Pure equipment, including head tank, distiller, rectifier, waste condensator, finished product condenser, the head tank connect described respectively
The cooling liquid inlet of waste condensator and the finished product condenser, the waste condensator and the finished product condenser it is cold
But liquid outlet is connected with circulating box, and the circulating box connects the head tank, is provided with water circulating pump in the head tank, institute
The water outlet for stating circulating box is connected with balancer, and the balancer connects the distiller, and the distiller connects the rectifying
Device, the rectifier both ends connect the waste condensator and the finished product condenser respectively.Acetic acid is being carried out using the structure
During purification, while cooling by water circulating pump circulation to waste condensator and finished product condenser in head tank
Peracetic acid temperature is lifted, so that acetic acid distillation institute calorific requirement is reduced.
In above-mentioned technical proposal, it is preferred that the distiller lower part is provided with heating unit.
In above-mentioned technical proposal, it is preferred that the distiller top is provided with some quartz glass tubes.
In above-mentioned technical proposal, it is preferred that overflow pipe is set in the connecting tube between the balancer and the distiller.
The utility model compared with prior art, has the advantages that：Using the structure when carrying out acetic acid purification,
Acetic acid temperature while cooling by water circulating pump circulation to waste condensator and finished product condenser in head tank
Degree lifting, so that acetic acid distillation institute calorific requirement is reduced.
