AI Technical Summary

Technical Problem

Existing gas-liquid mass-transfer heat transfer elements are susceptible to impact from gas-liquid mixture under large flux conditions, resulting in damage; gas-liquid separation is not thorough, forming mist entrainment, reducing mass transfer efficiency; the side discharge outlet area is limited during large volumes, resulting in an increase in flow resistance.

Method used

A highly efficient, ultra-large-flux impact-resistant three-dimensional gas-liquid mass-transfer heat transfer element is designed, and a combined structure of vertical plate, jet plate, open-hole reflective plate and outlet mechanism is adopted. Through the reflection of the spray holes and reflective plates on the jet plate, a streamlined gas-liquid flow route is formed, which reduces mist entrainment, and reduces flow resistance by increasing the outlet area and the use of fillers.

Benefits of technology

The effective separation of the gas-liquid mixture between the jet plate and the reflective plate is achieved, which reduces the fog entrainment and improves the mass transfer efficiency; by optimizing the flow route and increasing the outlet area, the flow resistance is reduced, and the impact resistance and overall strength of the component are enhanced.

Abstract

The invention discloses a high-efficiency super-large-flux impact-resistant three-dimensional gas-liquid mass and heat transfer element which comprises a vertical plate, one side of the vertical plate is connected with an injection plate, a plurality of injection holes are uniformly formed in the injection plate, one side of the injection plate is provided with a perforated reflecting plate, the upper end of the vertical plate is connected with a top plate, and the lower end of the vertical plate is connected with an inlet mechanism for gas and liquid to enter the element. An outlet mechanism used for discharging a part of mixed gas and liquid is arranged above the vertical plate, the inlet mechanism comprises a bottom plate, a bottom plate opening is formed in the bottom plate and used for a gas inlet, a cap cover bottom gap is formed in the lower end of the spraying plate and used for a liquid inlet, and the outlet mechanism comprises a cap cover top gap. In the process that gas and liquid in the cap cover flow upwards in parallel, a gas-liquid mixture penetrates through the spraying plate at a certain downward angle through the reflection effect of the reflection plate, further separation of the gas and the liquid is facilitated, entrainment is reduced, the gas-liquid flowing path in the cap cover tends to be streamline, and flowing resistance can be reduced.
