Integrated experiment system for measuring tank reactor amplification effect

Abstract

The invention discloses an integrated experiment system for measuring tank reactor amplification effect. Residence time distribution functions of three tank reactors with similar geometric structuresand same feeding and discharging positions are measured, so that the amplification effect of the tank reactors can be acquired. The system is provided with a water storage box, the electrical conductivity of inlet materials consistently keeps stable, effectiveness of experiment data is improved, generation of surface dead zones can be effectively avoided by the aid of an overflowing mode and an electrical conductivity probe, liquid level of reaction materials in the tank reactors can be controlled, amplification factors of the tank reactors are changed, a circular branch is arranged at an outlet of a water pump, the requirements of the three reactors for different feeding flow rates are met by one water pump, the system is simple in structure and convenient and rapid to operate, all experiment devices are integrated, functional partitions are reasonable, appearances are simple and elegant, and an experimenter can know definition of the reactor amplification effect and measuring methodof amplification rules through the system.

Description

technical field [0001] The invention belongs to the technical field of reactor analysis, and relates to a reactor amplification technology, in particular to an integrated experimental system for measuring the amplification effect of a kettle-type reactor. Background technique [0002] The chemical process is accompanied by the transfer of mass, heat and momentum. With the change of scale, the materials of production equipment, raw material specifications, production process conditions, production methods, product yield, etc. will all change, especially the process conditions and product yield. The large variability in laboratory results has been attributed to "magnification effects". In the development of chemical process, as long as the "magnification effect" problem of the reaction process is solved, other unit operation processes can be easily solved. Therefore, the chemical scale-up focuses on the scale-up criterion of the reactor, that is, the parameters need to be kep...
