Problems solved by technology

[0006] (2) In ZL94222825.1, the diaphragm distributor can keep the solid content in the tube bundle the same for heat exchangers (or reactors) with a small number of heat exchange tubes (or reaction tubes), but for those with dozens or The heat exchange system with hundreds of roots is difficult to realize due to the limited space and complicated structure.

Embodiment Construction

[0035] Below in conjunction with accompanying drawing, the present invention will be further described.

[0036] A device for evenly distributing each phase in a liquid-containing multiphase fluidization system. A material inlet 5 is arranged at the bottom of the lower tube box 3, and a casing structure 1 is arranged on the upper part of the lower tube box. The casing structure is composed of at least two nested tubes , the tubes are provided with a positioning device or the inner wall of the outer tube 6 and the outer wall of the inner tube 8 are fixedly connected, the relative positional relationship between the tubes is concentric or eccentric, and the outer tube may be a heat exchange tube, a reaction tube, or a crystallization tube One of the extraction and extraction tubes or the lower end of one of the heat exchange tubes, reaction tubes, crystallization tubes, extraction and extraction tubes is combined with the connecting tube 2, and the lower nozzle of the inner tube ...

Abstract

A uniform phase-distributing apparatus in the liquid-contained multi-phase fluidizing system where the density of solid phase is higher than that of liquid phase features that the material feeding inlet is arranged on the bottom of case, the sleeve pipe structure consisting of at least two nested pipes is arranged on the top of case, and the predistributor and master distributor are used. Its advantage is stable fluidizing state.

Description

technical field [0001] The invention relates to a heat exchange, reaction, crystallization, extraction and extraction equipment, in particular to a multi-phase uniform distribution device. Background technique [0002] Liquid-containing multiphase systems are widely used in chemical, energy, food processing and other fields. Such as the application in liquid-solid, vapor (gas)-liquid-solid circulating fluidized bed heat exchangers, evaporators, reboilers, crystallizers, extraction and extraction devices and tubular fluidized bed reactors. [0003] Due to the different fluidity of each phase in the liquid-containing multi-phase fluidized system and the complex interphase force, it has always been a very tricky task to evenly distribute the materials of each phase to the heat exchange tube bundle, reaction tube bundle, crystallization tube bundle, extraction and extraction tube bundle. The problem has not been able to find a good solution. Without a good uniform distribution...
