As shown in Figure 1-2, a kind of fluid bed, including fluid bed main body 1, for connecting fluid bed main body 1 and for fluid bed
The air supply system 2 of delivered inside cryogenic gas and the gas extraction system 3 for connecting fluid bed main body 1, the air supply system 2 are wrapped
Include the fluid passage of the air inlet connection heat exchanger 2a of heat exchanger 2a, air blower 2b and appendix 2c, the air blower 2b, institute
Appendix 2c one end connection air blower 2b, other end branch is stated to form multiple gas transmission branch pipe 2d and be connected with fluid bed main body 1.
The fluid bed that above-mentioned implementation method is provided, high temperature granular material enter after fluidized bed body 1 carried out on lathe bed it is defeated
Send, open the heat transferring medium (cryogenic gas) produced in air supply system 2 and gas extraction system 3, heat exchanger 2a by air blower 2b's
Effect is extracted, and by entering in each gas transmission branch pipe 2d after appendix 2c, then enters fluidized bed main body 1 by gas transmission branch pipe 2d
It is interior so that heat transferring medium is uniformly full of inside fluid bed main body 1, make high temperature granular material be adequately cooled, so that plus
Strong cooling effect, improve production efficiency, and will pass through gas extraction system 3 by the heat transferring medium after conversion and discharge.
Further, it is possible to the interface in gas transmission branch pipe 2d and fluid bed main body 1 sets gas diffusion plate 4, gas is expanded
Fall apart and 4 be removably installed on the inwall of fluid bed main body 1, several passages 4a is set on gas diffusion plate 4, when low
After wet body enters gas transmission branch pipe 2d, can be entered in fluidized bed main body 1 by the passage 4a on gas diffusion plate 4, due to logical
Stomata 4a further spreads out cryogenic gas, and then the cryogenic gas in fluid bed main body 1 is distributed more careful,
Uniformly so that cooling effect gets a promotion.
Preferably, passage 4a can be evenly spaced on gas diffusion plate 4, and makes passage 4a be in round platform
Shape, so when cryogenic gas passes through passage 4a, the state that can form diverging is sprayed in fluid bed main body 1 again, so just
So that cooling gas are in the more abundant of the interior diffusion of fluid bed main body 1.
As it is highly preferred that the interface of gas transmission branch pipe 2d and fluid bed main body 1 is located at the bottom of fluid bed main body 1, so
Can make cryogenic gas in gas transmission branch pipe 2d upwards eruption to fluid bed lathe bed, high-temperature particle is carried out it is sufficiently cool after take advantage of a situation
Again from the blast pipe 3a discharges at the top of fluid bed main body 1, make the smooth in exhaust of whole cooling procedure effective.
Further, gas extraction system 3 includes several blast pipes 3a, the connection row installed in the top of fluid bed main body 1
A left side of the air outlet connection casing 3c of the casing 3c of exhaust blower 3b and exhaust blower 3b the air outlet connection of tracheae 3a, exhaust blower 3b
Side, the bottom of casing 3c is provided with pond, and the left side top of casing 3c is provided with water curtain discharging device 3d, when waste gas enters blast pipe
3a, then when entering casing 3c by exhaust blower 3b, waste gas can pass through the water of water curtain discharging device 3d injections downwards, penetrate process
In, toxic and harmful will be absorbed by water curtain, and one is located at water pump connection pond and water curtain discharging device 3d outside casing 3c,
So that the water energy in pond is enough recycled, saving water resource is finally further opened with exhaust outlet on the right hand top of casing 3c
3e, the gas discharged eventually through exhaust outlet 3e does not return pollution workplace and surrounding environment, protects health.
Preferably, blast pipe 3a can be set to arch, the outlet side of blast pipe 3a is gradually expanded and is connected
There are material blanking tube and exhaust column, material blanking tube is connected the end of blast pipe 3a outer arcs, exhaust column is connected the end of blast pipe 3a inner arcs
End, material blanking tube is connected with disposal box 3f, and exhaust column is connected by an exhaust branch pipe 3g with exhaust blower 3b, due to existing in fluid bed
Substantial amounts of dust granules material, when its top carries out exhausting, part dust granules material can be with the gas one in fluid bed
With extracting out, if blast pipe 3a is set into arch, dust can be due to the resistance shadow by wind-force and blast pipe 3a outer arc inwalls
Ring and close to the inwall advance of blast pipe 3a outer arcs, finally because self gravitation falls into blanking port, then gathered up by disposal box
Come, and gas is relatively small due to density, therefore can be in the flowing underneath of dust until entering taking out for blast pipe 3a inner arcs end
Air port, then entered in casing 3c by exhaust blower, the water curtain dedusting burden of casing 3c just can be so reduced, it is further ensured that exhaust outlet
The gas safety of 3e discharges is pollution-free.
Above-described embodiment is the utility model preferably implementation, and in addition, the utility model can be with other sides
Formula realizes that any obvious replacement is in protection model of the present utility model on the premise of the technical program design is not departed from
Within enclosing.
In order to allow those of ordinary skill in the art more easily understand the utility model relative to prior art improvement it
Place, some accompanying drawings of the present utility model and description have been simplified, and for the sake of clarity, present specification is omitted one
A little other elements, those of ordinary skill in the art should be aware that these elements for omitting also may make up in of the present utility model
Hold.
