Gas liquid mixing apparatus by jet circulation reaction characteristics

Abstract

The invention relates to dead water, sewage and waste water processing equipment or a chemical industry equipment, in particular to a jet loop reactor which leads the collision and mixing between processing water and gases such as oxygen or ozone, etc., by jetting gas-liquid from a composite nozzle in a processing cylinder and simultaneously forming the annular flow in an inducing pipe; the inducing pipe is provided inside with a conical diffuser and a convex part, for increasing contact area between the gases and the liquid and residence time in the processing cylinder, thereby improving the gas-liquid mixing performance. The invention improves the gas-liquid mixing performance of the jet loop reactor and further achieves the effect of improving the gas-liquid mixing.

Description

technical field [0001] The present invention is equipment or chemical industrial equipment for treating still water, sewer water and waste water. Specifically, it sprays gas and liquid simultaneously in a treatment tank through a composite nozzle, and forms an annular flow through an induction tube to make the treated water and oxygen or A jet loop reactor in which gases such as ozone collide and mix. Among them, the conical diffuser and the protruding part arranged in the induction tube increase the contact area between the gas and the liquid and the stagnation time in the treatment tank, thereby improving the performance of gas-liquid mixing. Background technique [0002] figure 1 and figure 2 Schematic of the conventional jet loop reactor structure: it consists of the liquid inlet pipe 31 inserted into the gas inlet pipe 32, the treatment tank 10 formed by the outlet pipe 11, and the barrel-shaped induction tube 20 arranged in the treatment tank 10. Externally, a trea...

Problems solved by technology

[0005] However, in this conventional jet loop reactor, the gas-liquid mixing of the input liquid and gas only depends on the annular flow, so the efficiency of gas-liquid mixing is limited to a certain extent.
