Abstract
The utility model provides a multistage circulating and drying fluidized bed, comprising a fluidized bed body divided into upper and lower parts by an air distribution plate. The fluidized bed is divided into multiple stages of fluidized cavities by an upper partition plate and a lower partition plate, which are respectively disposed at the upper and lower parts of the air distribution plate and disposed corresponding to each other. A gap is provided between the upper partition plate and the air distribution plate. Each stage of fluidized cavity is provided with an air outlet disposed at the upper part and an air inlet disposed at the side edge of the lower part. An air outlet of a first stage fluidized cavity is connected to a dedusting device, and the air outlet of each stage of the fluidized cavity is connected to the air inlet of the fluidized cavity of the above stage through an air circulating pipe having a circulating shaft flow blower. The multistage circulating and drying fluidized bed is advantageous in that the drying process is easy to control; air for drying materials have multiple times of contact with materials, and the utilization rate of heat energy is high; through a sufficient contact between the drying air and the materials, the even drying of produces is realized, and a part of hydrates can be prevented from producing crystallization water due to overdrying.
Description
Technical field
The utility model relates to multilevel drying equipment, particularly can be used for the multi-staged air circulating fluidised bed apparatus of dry hydrate.
Background technology
At present, adopt vibrated fluidized bed that moisture hydrate is carried out drying usually.Under condition of overhigh temperature, hydrate can be deviate from partially crystallizable water, therefore, and the difficult control of its drying.The drying of existing hydrate is to adopt the air of a large amount of lower temperatures in fluidized bed, once to contact with material, because dry air only once contacts with material, the consumption of air is very big, and energy consumption is high.Simultaneously, when drying air temperature was low, product can occur dry not enough; When drying air temperature was higher, over-drying, the efflorescence of product caused the loss of product yield, and in follow-up storage and transport process, lumpd easily.
The patent No. is that the utility model of zl201020533439.8 discloses a kind of vibrated fluidized bed.When adopting this equipment that material is carried out drying, the air that is used for dried material only once contacts with regard to device for transferring with material, and the heat energy utilization rate is low, and energy loss is big.
Summary of the invention
The purpose of the utility model provides the dry fluid bed of the sufficient multi-stage countercurrent of a kind of energy utilization.
For realizing that the technical scheme that the utility model purpose adopts is such; One is divided into up and down two-part fluid bed body by gas distribution grid; It is characterized in that: some corresponding up and down upper spacer and the lower clapboards that lay respectively at said gas distribution grid upper and lower are separated into some grades of fluidizing chambers with fluid bed; Gapped between said upper spacer and the gas distribution grid; Each grade fluidizing chamber has air outlet slit that is positioned at the top and the air intlet that is positioned at the lower part side; The air outlet slit of said first order fluidizing chamber links to each other with cleaner, and the air outlet slit of all the other each grade fluidizing chambers is connected through the air with circulation axis flow fan with the said air intlet of upper level fluidizing chamber.
The utility model is owing to said structure, and its advantage is: dry run is controlled easily.The air that is used for dried material repeatedly contacts with material, and the heat energy utilization rate is high, and needed air capacity significantly reduces during fluidization, and the installed capacity of fluid bed and thermal energy consumption all reduce greatly.Through fully contacting of dry air and material, it is over-drying that the not enough and other part of local desiccation can not appear in product.The utility model has prevented that hydrate is because of deviating from the efflorescence of partially crystallizable water and in storage and transport process, luming.
Description of drawings
The utility model can further specify through the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is the front view of the utility model;
Fig. 2 is the cutaway view of the utility model.
Among the figure: 1, charge door; 2, air outlet slit; 4, fluid bed body; 5, upper spacer; 6, go up fluidizing chamber; 7, discharging opening; 8, vibration isolation spring; 9, following fluidizing chamber; 10, lower clapboard; 11, air; 12, circulation axis flow fan; 13, vibrating motor; 14, air intlet; 15, hand hole; 16, gas distribution grid.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to accompanying drawing; The utility model provides and comprises that one is divided into up and down two-part fluid bed body 4 by gas distribution grid 16; Wherein: the corresponding up and down upper spacer 5 of three couples that lays respectively at said gas distribution grid 16 upper and lowers is separated into the level Four fluidizing chamber with lower clapboard 10 with fluid bed; Gapped between said upper spacer 5 and the gas distribution grid 16; Each grade fluidizing chamber has air outlet slit 3 that is positioned at the top and the air intlet 14 that is positioned at the lower part side; The air outlet slit 3 of said first order fluidizing chamber links to each other with cleaner, and the air outlet slit 3 of all the other each grade fluidizing chambers is connected through the air 11 with circulation axis flow fan 12 with the said air intlet 14 of upper level fluidizing chamber.
The foregoing description is separated into four independently fluidizing chambers with traditional vibrated fluidized bed inside; Air intlet 14 is opened in side at following fluidizing chamber 9; The bottom of each fluidizing chamber is an inverted cone-shaped structure, so that just in case have material when gas distribution grid 16 leaks down, conveniently to take out from the hand hole 15 of boring the end.16 of upper spacer 5 and gas distribution grids have the slit.Said fluid bed body 4 bottoms have vibration isolation spring 8, and its side has vibrating motor 13.Under the vibration effect, material is through the slit between 16 of above-mentioned upper spacer 5 and the gas distribution grids, and a fluidizing chamber moves to a fluidizing chamber afterwards in the past.Said slit can according to dry material confirm that this slit in the present embodiment is between 0.05-0.15 rice.The gas that comes out of fluidizing chamber 6 following fluidizing chamber 9 through air 11 entering upper levels under the effect of circulation axis flow fan 12 on the one-level of back.Circular flow axial flow blower 12 is equipped with the frequency conversion flow regulators, changes the air mass flow of each grade through the revolution of regulating every typhoon machine, prevents to collaborate between not at the same level.
