multiphase flow reactor

Abstract

The invention discloses a multiphase flow reactor and relates to a reactor. An inlet shell, a stage shell, a tail stage shell and an outlet shell are fixed integrally through connecting screws; an O-shaped ring and a first impeller are arranged between the inlet shell and the stage shell, an O-shaped ring and a second impeller are arranged between the stage shell and the tail stage shell, and an O-shaped ring, an elastic gasket and a seal are arranged between the tail stage shell and the outlet shell; one end of a shaft is connected to a coupler, and the other end of the shaft sequentially penetrates a protecting cover, a middle disc, a cover, the outlet shell, the seal, the tail stage cover, the second impeller, the stage shell and the first impeller to connect with a shaft sleeve of the inlet shell. The multiphase flow reactor has the advantages that according to the actual requirements, the numbers of stage shells and impellers between the first impeller and the tail stage shell are increased and decreased flexibly, the gas, liquid and solid phases are mixed rapidly and completely, the effect of diffusion is achieved, the reliability is high, the energy saving effect is significant, the durability is high, the device processing effect is improved, and the operation cost is reduced.

[0002] Nowadays, multiphase flow reaction, dissolved air flotation, dissolved air process, neutralization process, rust removal, wastewater denitrification, ozonation treatment of drinking water, process water, heavy water and wastewater reuse technology in chemical production units In the traditional way, air compressors, pressure vessels, releasers, control systems and valves or centrifugal pumps are still used to transport media, such as centrifugal pumps, whose typical application is to transport liquids. However, in practical applications, this method only transports pure The ideal state of the liquid is not common, for example air is sucked into the pump due to installation problems on the suction side, a liquid level that is too low in an open system can also cause air to be sucked into the pump; on the other hand, in the process industry In the process, the gas and liquid are required to be in a critical state, and it is often necessary to transport liquids containing undissolved gases or vapors. Therefore, in many practical engineering applications, it is very common to transport multi-phase coexisting media, such as dissolved gas liquids, liquid-gas mixtures, and gas-jet liquids must be able to deliver both stably and reliably

[0003] Due to the problem of the impeller structure of the non-self-priming centrifugal pump, the operation in this case will cause damage to the pump or cannot run stably. When the air content increases, there will be more and more air bubbles in the middle of the impeller, which will eventually hinder the flow of liquid. Even if the liquid contains little gas, the characteristic curve of the pump will be very unstable, so the general-purpose centrifugal pump cannot meet the stable operation under such working conditions, and other forms of containers have this problem. aspects of the problem
