Description
Technical field
Technical field of cement production is the utility model is related to, more particularly to a kind of grate-cooler.
Background technology
In the prior art, grate-cooler is the critical host equipment in the sinter leaching system of cement plant, and its major function is
Clinker is cooled down, conveyed；Hot-air is provided for rotary kiln and dore furnace etc. simultaneously, is the master of firing system recuperation of heat
Want equipment.But because grate-cooler uses step cooling down more, heat can be reduced step by step, therefore grate-cooler first section heat be present
Greatly, the problem of flue gas is few, and tail end heat is small, flue gas is big, existing waste heat recovery system of grate cooler lack the design of both balances,
Cause waste heat recovery efficiency low, and easily break down.
Utility model content
Mainly solving the technical problems that providing a kind of grate-cooler, carry out multisection type waste heat to grate-cooler returns the utility model
Receive, to improve waste heat recovery efficiency.
To solve above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of grate-cooler, it is characterised in that：Including ladder-type grate-cooler body, and it is respectively connected with every grade of body remaining
Recuperation of heat passage；It is staggeredly equipped with multiple heat absorption plates in the first order waste heat recovery passage of the body, and more than the first order
Thermal isolation film is provided with recuperation of heat conduit wall；Multiple smoke filtration nets are provided with the tail level waste heat recovery passage of the body；
Side is arranged at intervals with heat absorption plate in the interlude waste heat recovery passage of the body, and is set at waste heat recovery feeder connection
It is equipped with smoke filtration net；The smoke filtration net comprises at least layer of active carbon stratum reticulare.
Further, production material transmission line is provided with the body.
Further, the waste heat recovery passage is communicated to waste heat boiler.
Further, the tail level waste heat recovery channel end of the body is provided with exhaust gas fan.
Further, the tail level waste heat recovery passage of the body is connected with the tail of dust branch road, dust branch road and body
Level waste heat recovery passage junction is provided with switching valve.
Further, the dust branch road is connected with dust separator.
The beneficial effects of the utility model are：The situation of prior art is different from, the utility model sets grate-cooler body
Ladder-type is set to, and is connected to waste heat recovery passage, and every grade of waste heat passage enters according to near-far situation, exhaust gas volumn size
Row separately designs, in the waste heat recovery passage of chopped-off head to set heat exchanger plate more, heat absorption is increased, in the waste heat recovery of tail level
Passage increases the processing to flue gas, avoids polluting and blocks next stage and presets reclaimer（Waste heat boiler etc.）.
Brief description of the drawings
Fig. 1 is grate-cooler structural representation provided by the utility model.
Marked in figure：1 be body, 2 be production material transmission line, 3 be first order waste heat recovery passage, 4 be heat absorption plate,
5 it is interlude waste heat recovery passage, 6 be tail level waste heat recovery passage, 7 be smoke filtration net, 8 is dust branch road.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of grate-cooler, including ladder-type grate-cooler body 1, and be respectively connected with every grade of body 1
Waste heat recovery passage；Multiple heat absorption plates 4 are staggeredly equipped with the first order waste heat recovery passage 3 of the body 1, and first
Thermal isolation film is provided with the wall of level waste heat recovery passage 3；Multiple flue gases are provided with the tail level waste heat recovery passage 6 of the body 1
Screen pack 7；Side is arranged at intervals with heat absorption plate 4 in the interlude waste heat recovery passage 5 of the body 1, and in waste heat recovery
Smoke filtration net 7 is provided with feeder connection；The smoke filtration net 7 comprises at least layer of active carbon stratum reticulare.
Production material transmission line 2 is provided with the body 1.
The waste heat recovery passage is communicated to waste heat boiler.The end of tail level waste heat recovery passage 6 of body 1 is provided with useless
Gas blower fan, the tail level waste heat recovery passage 6 of body 1 are connected with dust branch road 8, the tail level waste heat recovery of dust branch road 8 and body 1
The junction of passage 6 is provided with switching valve.The dust branch road 8 is connected with dust separator.
In actual use, 1000 DEG C -1200 DEG C of material has been heated to it and has been passed into grate-cooler, material is with body
Production material transmission line 2 in 1 moves, and is progressively cooled.Every grade on body 1 of waste heat recovery is now opened to lead to
Road, in the waste heat recovery passage of the first order, recovered temperature can reach 800 DEG C -900 DEG C, at this time, it may be necessary to more heat absorption plates 4
Accelerate absorption efficiency.And as the gradual cooling of material, waste heat recovery temperature gradually reduce, flue gas increase, arrive the recovery of tail level
When, it is necessary to dust carry out extra process, effectively absorbed using active carbon layer.When having thrown away a large amount of dust into more than next stage
During Equipment for Heating Processing, the active carbon layer needs that failed are changed, and can open standby dust branch road 8, utilize dust point
Handled from device, and active carbon layer is changed in time.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using utility model specification and accompanying drawing content, or directly or indirectly it is used in it
The technical field of his correlation, is similarly included in scope of patent protection of the present utility model.
