Screening and uniform distribution of the device in feed zone high-temperature solid bulk cargo, wherein bulk-material screening is by gravity and shakes
The comprehensive function of sieve (there are oscillation crosswises) is moved to realize；Uniform distribution is by digging on arc supports for material down-sliding curved surface and curved surface
" item thread " shape screening is stitched to realize.
Wherein, supports for material down-sliding curved surface, that is, it is arc to sieve plate face 1, and along falling head, slope is gradually relatively low, peak
The angle of repose of particle phase must be more than with the inclination angle at 1/3 position of feed hopper (i.e. at O points), to promote the smooth downslide of material, and
It prevents the speed for declining curved surface end particle phase to be unlikely to accelerate excessive (the predominantly particle of greater particle size), while sieving plate face
1 adjustable tilt degree, so as to control the flow rate of charging and ensure the uniform of throat-fed and stablize.
The screening seam of downslide curved surface is processed as " item thread shape ", and screening seam number in upside is more, and narrower width is mainly used for sieving
Gradation diameter smaller particle is used for right side indirect heat exchange, and heat transferring medium can be water/gas/vapour；Screening seam number in downside is less, wide
Degree it is wider, be mainly used for sieve greater particle size particle, for left side (water/gas/vapour) cold type indirect heat exchange and it is air-cooled directly
Heat exchange.The thickness of screening seam is 10-25mm, and cross section is " trapezoidal ", can effectively weaken particle and bond obstruction screening seam.
Entire sieving plate is controlled by mechanical vibrator 2, can apply the vibration of horizontal direction, when solid granule is in sieve pore
Between when blocking, pass through the particulate mass for vibrating and removing and blocking in screening seam.
3 upside of feed hopper is higher by the part setting striker plate 12 that solid granule declines curved surface, for weakening the splashing of bulk cargo
Or it overflows.
For the particle compared with small particle, it is in-line arrangement that snakelike comb 5, which is arranged, tube side-shell fluid flow direction be it is reverse-flow, for
The particle of greater particle size, is arranged directly-indirect heat exchange mixing chamber 10, and upside uses (water/gas/vapour) cold type indirect heat exchange, downside

Discharge zone is independently arranged discharge bucket 7 to each Heat Room, and the mass flow of discharge is controlled by discharge valve 14, into
And control the residence time of different-grain diameter solid granule.
In actual use, high-temperature solid bulk cargo pass through supports for material down-sliding curved surface, that is, sieve plate face 1 carry out screening and
After even cloth, enters the cold water being passed through in indirect heat exchange room 11 and snakelike comb 5 compared with the particle of small particle and carry out indirect heat exchange；Compared with
Large-size particles then enter directly-indirect heat exchange mixing chamber 10, and (water/gas/vapour) cold type indirect heat exchange is used on the upside of mixing chamber,
Downside uses air-cooled direct heat transfer.Cold wind passes through blower, after entering Heat Room heat exchange by air inlet 8, from exhaust
Mouthfuls 9 are discharged, and Gas-particle Flows direction is cross-current type, the preheated air of the air of discharge as boiler combustion.Indirect heat exchange segment pipe
It is arranged as snakelike comb 5, is set as 8-10 tube sides (improving the quality of heat transferring medium and considering for crushing balance), tube side-
Shell fluid flow direction is reverse-flow, is sent from the hot water of outlet discharge to steam turbine and carries out cogeneration.
Supports for material down-sliding curved surface sieves 1 structure of plate face as shown in Fig. 2, it is arc that material, which declines curved surface, along decline height
Degree, slope continuously decrease, and peak must be more than the angle of repose of particle phase with the inclination angle at 1/3 position of feed hopper (i.e. at O points).Under
The screening seam of sliding curved surface is processed as " item thread shape ", and screening seam number in upside is more, narrower width, is mainly used for screening compared with small particle
Particle, into right side (water/gas/vapour) cold type indirect heat exchange room 11 exchange heat；Screening seam number in downside is less, and wider width is main
It is used to sieve greater particle size particle, direct-indirect heat exchange mixing chamber 10 into left side exchanges heat.The thickness of screening seam is 10-
25mm, cross section are " trapezoidal ", as shown in figure 3, can effectively weaken particle bonds obstruction screening seam.Entire sieving plate is by machinery
Vibrating device 2 controls, and can apply the vibration of horizontal direction.
For striker plate 12 to weaken splashing or the spilling of bulk cargo, adjustable-pitch device is arranged in screening plate face 1, to
The mass flow for controlling inlet feed, ensures the uniform of throat-fed and stablizes.
The cross section of guide plate 13 reduces the discharging of solid granule as shown in figure 4, can extend the residence time of particle phase
Mouthful temperature, while guide plate 13 is located at the setting of heat exchanging segment central area and divulges information that number of perforations is more, and vent area is larger；Positioned at side
Number of perforations of divulging information at wall is less, and vent area is smaller, ensures that the decrease speed of solid granule is uniform.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
