Abstract
The invention relates to a flash distillation apparatus, and in particular relates to a fast flash distillation apparatus which comprises a kettle type heater, a major-diameter reducer pipe, a condenser, a material receiver and a high-vacuum pump unit. By adopting the technical scheme, the invention solves the problems of low yield, instable quality, low-speed rectification in the prior art. The invention ensures that the material distillation process can be fast completed, and simultaneously avoids oxidation, polymerization, decomposition, coking and other phenomena in the distillation process, thereby sufficiently removing impurities from the product, improving the product purity and yield, enhancing the equipment production capability, and greatly saving the production time and energy.
Description
Technical field
The present invention relates to the distillation equipment in the fine chemical product production process, particularly flashing apparatus fast and efficiently is applicable to the material of higher boiling, thermal sensitivity.
Background technology
General distillation equipment comprises axe formula heater, Steam Pipe, condenser, material receiver, vavuum pump at present.Chuck is housed around the still formula heater is used for heating, generally its volume is 500L: 3m with the heating surface (area) (HS ratio
2Hot side is long-pending little because still is experienced, material is subjected to thermal velocity slow, cause distillation time length and cause that bottom sediment is many, yield is low, and because the characteristic of higher boiling, heat sensitive material, distillation time is long to cause phenomenons such as material oxidation, polymerization, decomposition, coking easily, makes loss of material, reduce product yield and quality greatly, increase production cost and energy consumption.
Summary of the invention
The objective of the invention is to, a kind of quick flashing apparatus is provided, solve material and be subjected to thermal velocity to cause distillation time long and influence the problem of product quality, yield slowly.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of quick flashing apparatus comprises as lower device: still formula heater, major diameter reducer pipe, condenser, material receiver, high-vacuum pump unit is characterized in that described still formula heater storage is 500L: 10m with the heating surface area ratio
2
Described still formula heater base is equipped with heating jacket.The heating tubulation is equipped with in described still formula heater inside.This device makes the heating surface area of material increase greatly, be heated evenly, and speeds the evaporation capacity of material, thereby shortens distillation time, reduces the generation of side reaction and bottom sediment amount.Use the final products yield and the quality of this device to improve greatly.
Big mouthful of diameter of described major diameter reducer pipe is 1/2 of described still formula heater diameter.
Big mouthful of diameter of described major diameter reducer pipe is 2 times of osculum diameter.
Described major diameter reducer pipe is provided with the condensation chuck.Make vaporized gas volume-diminished after cooling off, reduce resistance by pipeline.
Big mouthful of diameter place of described major diameter reducer pipe is provided with demister.The taking out of of drop when preventing flash distillation makes pipeline unimpeded.
Operational process of the present invention is: the material that at first will need to handle drops into described still formula heater, open described high-vacuum pump unit then, make vacuum progressively reach the desired vacuum of product, open the Circulation and Hot Oil Spray system subsequently and heat, control temperature by the temperature requirement of different fractions.Material is subjected to thermal evaporation, by described major diameter reducer pipe.Open described condenser cooling water simultaneously, material is through described condenser condenses, and distillate enters described material receiver.
