Intelligent multifunctional return distillation instrument

Abstract

The invention discloses an intelligent multifunctional return distillation instrument which comprises a worktable and a temperature acquisition device. A plurality of flasks, heating devices and return pipes with openings are arranged on the worktable, the flasks are provided with reflux inlets and temperature acquisition ports, the heating devices are used for heating the flasks and accelerating reaction of solution in the flasks, one return pipe is connected with the reflux inlet of each flask and extends towards the upper portion of the flask, and a cooling device is arranged on the outer side of each return pipe and used for cooling the return pipe when solution in the corresponding flask is heated and evaporated to enter the return pipe, so that condensed water vapor solution returns into the flask. The heating devices and the cooling devices are electrically connected with a controller, and the temperature acquisition device is matched with the temperature acquisition ports of the flasks, extends into the flasks from the temperature acquisition ports and is used for detecting the temperature of the solution inside the flasks, and the temperature acquisition device is electrically connected with the controller. The intelligent multifunctional return distillation instrument can prevent the solution from incomplete reaction in the boiling evaporation process due to different solute evaporation capacity, and is simple in structure, accurate in testing data, simple and convenient to control and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of distillation, in particular to an intelligent multifunctional back distillation apparatus. Background technique [0002] Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. The oxygen equivalent of substances (generally organic matter) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. In the study of river pollution and the nature of industrial wastewater and the operation and management of wastewater treatment plants, it is an important and quickly measured organic pollution parameter, often expressed by the symbol COD. [0003] A high COD means that the water contains a lot of reducing substances, mainly organic pollutants. The higher the chemical oxygen demand, the more serious the organic matter pollution of the river water. The source of these organic m...

Problems solved by technology

[0005] During the reaction process, due to the different boiling points of the substances, there is evaporation during the boiling process, and the evaporation quality of each substance will also be different, which leads to incomplete reaction, causes errors, and affects the COD detection and measurement value.
