Description
Technical Field
The utility model relates to a device for uniformly dispersing gas media in the chemical field; in particular to a microporous plate gas distributor.
Background
In the chemical production process, gas outside the equipment is generally required to be introduced into the equipment to perform mass transfer or chemical reaction with a contact element (such as liquid material, a tray, a catalyst and the like) in the equipment; however, the phenomenon of uneven gas distribution is often caused by directly introducing a pipeline for external gas of the equipment into the equipment, and the conditions of local concentration or gas dead zones (no gas inflow) and the like occur, so that the mass transfer effect and the reaction efficiency of a contact part in the equipment are seriously influenced; to avoid this, a gas distributor is often installed in the apparatus so that the gas entering the apparatus can be uniformly distributed to the contact members.
The gas distributor can be divided into a tube type, a bubble cap type, a nozzle type, a plate type and the like, and at present, the two types of the tube type gas distributor and the plate type gas distributor are mostly used in domestic industry; the tubular gas distributor has the advantages of small pressure drop, difficult deformation, light weight, capability of simplifying the internal structure of the device, capability of reducing the height of the device and the like. However, the diameter of the bubbles generated by the tubular gas distributor is large, reaching several or even tens of centimeters, and although the tubular gas distributor is suitable for a slow reaction process, the liquid in the equipment is seriously mixed back, the bubbles are easy to generate coalescence, and the reaction efficiency is low. With the continuous development of fields such as petrochemical industry, the existing tubular distributor can not meet the current development requirements and can not well distribute gas into equipment uniformly.
At present, other methods for strengthening gas-liquid mixed contact are researched, such as increasing the pressure in the tower, adopting a turbine mixer, stirring by a mechanical impeller in the tower and the like, the mechanical strengthening methods have high energy consumption and cost and are difficult to use on a large scale, and a strong disturbance effect is generated on a chemical process which needs to keep a static reaction state to separate a third product, so that the separation effect of a reaction result is influenced.
In other methods, such as electric field enhancement and ultrasonic excitation, the external force field is adopted to enhance gas-liquid contact mixing, and more small bubbles are generated in the reactor, so that the contact area between gas and liquid is increased, but the equipment investment is greatly increased.
Patent number ZL 200920117879.2 discloses a plate-type gas distributor, which adopts a form of making conical holes on the distribution plate to distribute gas; through practical application, although the problem of hole blockage is avoided to a certain extent in the form of the conical holes, the diameters of the conical holes in the distribution plate are 0.01-5mm, the diameters of the conical holes are small, the processing and manufacturing difficulty is high, the processing precision of the taper and the hole diameter of each conical hole cannot be guaranteed, and the deviation of the taper and the hole diameter is easily caused, so that the sizes of generated bubbles are different; in addition, the thickness of the distribution plate in the patent reaches more than 2mm, and in long-term use, solid impurities in the materials can be accumulated at the conical hole, and the distribution hole can be blocked after a certain time, and the distribution plate is difficult to wash and recover.
The gas that exists among the prior art is difficult to distribute evenly, the easy problem of blockking up, washing difficulty of distributor in equipment, the utility model provides a micropore board gas distributor to solve above-mentioned difficult problem, provide a simple structure, do not influence liquid flow and the effectual distributor of gas distribution.
