Abstract

The invention discloses a multi-stair circulating type jet reactor which comprises a body, a jet pipe, an external circulating pipe, a circulating pump and a stair circulating pipe, wherein a reaction chamber is arranged in the body; a feeding port, a discharging port, a circulating discharging port and a circulating feeding port are arranged on a wall of the reaction chamber; the jet pipe is inserted into the reaction chamber through the circulating feeding port; a first end of the external circulating pipe is communicated with the circulating discharging port; a second end of the external circulating pipe is communicated with an inlet of the jet pipe; the circulating pump is arranged on the external circulating pipe; the stair circulating pipe is arranged in the reaction chamber; an outlet end of the jet pipe is inserted into the stair circulating pipe through the inlet of the stair circulating pipe. The multi-stair circulating type jet reactor according to the embodiment of the invention has the advantages of excellent mixing performance, low energy consumption, and the like.

Description

technical field [0001] The present invention relates to reactors, in particular to step-circulation jet reactors. Background technique [0002] The jet reactor is a form of reactor with high-intensity mixing effect. It uses high-speed fluid jetting so that the reactants can be sheared into tiny particles and fully mixed, increasing the contact area between the phases of the reactants, and can strengthen the Mass transfer and heat transfer can speed up the reaction rate, improve the concentration and temperature distribution, suppress side reactions, and improve the selectivity of the reaction. Therefore, the jet reactor is especially suitable for gas-liquid, liquid-liquid and other multi-phase reaction processes. With the economic development, the expansion of industrial production scale and the requirement of reducing energy consumption, jet reactors are also increasingly required to be larger and have a variety of internal structures. [0003] But in the enlargement proce...

Problems solved by technology

Therefore, existing jet reactors either have good mixing performance but high energy consumption or low energy consumption but poor mixing performance

[0004] The traditional jet reactor can only form a jet flow, and at the end of the jet flow, there is still a considerable amount of kinetic energy and potential energy that has not been guided for use, resulting in very uneven disturbance of the reactants at the lower end of the reaction chamber of the reactor, which will make A lot of kinetic energy and potential energy are converted into heat energy, which reduces the energy utilization rate of the reaction and increases the uncontrollability of the reaction
