Abstract
The utility model discloses a fluidized bed gas distributor base, package rubbing board personally experiences sth. Part of the body, sets up the zone of aeration on the plate body, its characterized in that: still include the microwave heating pipe, every the bar air vent that includes a plurality of evenly distributed on the zone of aeration, the zone of aeration with the microwave heating intertube separates evenly distributed. Compared with the prior art, the hot air circulation in bar hole of ventilating is big for the material of tiny particle and the material of large granule can all the fluidizations, can not produce the phenomenon that flows and block up of granule. Microwave heating pipe evenly distributed makes the hot -air obtain secondary heating on the plate body, and the material makes the material rapid heating with distributing plate contact while, microwave heating pipe, makes the large granule resolve into the tiny particle, further improves the work efficiency of fluidized bed. And to the material of difference, can adjust little wave frequency in the microwave heating pipe for the effect effect of microwave can be according to the material of difference and the difference, remains the maximize of effect throughout.
Description
Technical field
The present invention relates to a kind of new gas distribution grid, particularly a kind of gas distribution grid be applied on fluid bed.
Background technology
Among the fluid a large amount of solid particle being suspended in motion, thus make particle have some appearance features of fluid, the solid contact condition of this stream is called fluidization of solid, and fluidization of solid technology generally applies on fluid bed.The gas distribution grid of fluid bed, can make the gas uniform distribution entering into fluid bed, effectively reduces fluid bed because internal gas skewness causes bed inside to produce the generation of the problems such as hole, channel and dead bed.Under normal circumstances, gas distribution grid in fluid bed is evenly covered with ventilation circular hole, according to the equally distributed distribution grid of ventilation circular hole, often produce short grained material and start fluidisation and the phenomenon of oarse-grained material also not yet fluidisation, easily cause the phenomenon that the flowing of particle blocks, increase fluidizing gas velocity if continue, make oarse-grained material start fluidisation, short grained material then produces elutriation, makes drying efficiency greatly reduce like this.Therefore, develop a kind of fluid bed that can solve to produce the gas distribution grid of clogging because material particles varies in size and seem particularly important.
Utility model content
Technical problem to be solved in the utility model provides a kind of fluid bed that solves to produce the gas distribution grid of clogging because material particles varies in size.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of fluidized bed gas distribution grid, comprise plate body, the zone of aeration be arranged on plate body, it is characterized in that: also comprise heating using microwave pipe, zone of aeration described in every bar comprises some equally distributed bar shaped passages, described zone of aeration and described heating using microwave pipe interval are uniformly distributed.
Compared with prior art, the thermal air current flux of ventilation bar hole is large, makes short grained material and oarse-grained material can fluidisation, can not produce the phenomenon of the flowing blocking of particle.Heating using microwave pipe is evenly distributed on plate body, makes hot-air obtain post bake, and material contacts with distribution grid simultaneously, and heating using microwave pipe makes material Fast Heating, makes bulky grain resolve into granule, improves the operating efficiency of fluid bed further.And for different materials, heating using microwave Guan Zhongwei wave frequency can be regulated, make the action effect of microwave can be different according to different materials, remain the maximization of effect.The utility model can solve fluid bed and produce the problem of particle flow blocking because material particles varies in size, and adopt heating using microwave pipe to make heating particles speed fast, efficiency is high, homogeneous heating, makes dry materials abundant.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram.
In accompanying drawing: 1 represents plate body, 2 represent zone of aeration, and 21 represent bar shaped passage, and 3 represent heating using microwave pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, fluidized bed gas distribution grid in the present embodiment, comprise plate body 1, the zone of aeration 2 be arranged on plate body, it is characterized in that: also comprise heating using microwave pipe 3, zone of aeration 2 described in every bar comprises some equally distributed bar shaped passages 21, described zone of aeration 2 and described heating using microwave pipe 3 interval are uniformly distributed.When material enters on the plate body 1 of fluidized bed gas distribution grid, zone of aeration 2 comprises some equally distributed bar shaped passages 21, thermal air current flux is large, short grained material and oarse-grained material is made all to carry out fluidisation, in time being evenly distributed on the heating using microwave pipe 3 on plate body 1, heating using microwave pipe 3 makes material Fast Heating, makes bulky grain resolve into granule, the operating efficiency of further raising fluid bed, also makes hot-air obtain post bake.Heating using microwave pipe 3 firing rate is fast, and homogeneous heating is pollution-free, and regulates micro-wave frequency in heating using microwave pipe 3, makes the action effect of microwave can be different according to different materials, remains the maximization of effect.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the present invention and claims, various replacement, change and amendment are all possible, therefore, scope of the present invention is not limited to the content disclosed in embodiment and accompanying drawing.
