Description
Technical field
The present invention relates to heat recovery technical field, particularly relate to solid thermal carriers heat recovery field,
Chiller particularly for solid thermal carriers bootstrap system.
Background technology
Generally can generate substantial amounts of high temperature slag, slag in Metal Melting production process, in Conventional process these
High temperature slag, slag directly would generally be discarded after cooling down, on the one hand cause the waste of resource, and it is right on the other hand to will also result in
The pollution of environment.Occurring a kind of solid thermal carriers bootstrap system at present in this area, see Fig. 1, it first passes through cooling dress
Put the solid thermal carriers of 10 pairs of high temperature to cool and produce the high-temperature flue gas reaching specified use temperature, the height of generation simultaneously
Temperature flue gas carries out UTILIZATION OF VESIDUAL HEAT IN by waste heat boiler 20, and then the flue gas after cooling is arranged by chimney by after dust arrester 30 dedusting
Going out, the heat of high-temp solid heat carrier can be recycled by effectively, thus play the saving energy, eliminate directly discharge
And the problem causing environmental pollution.Chiller 10 therein includes rotary kiln 12, and the two ends of rotary kiln 12 are respectively by end
Lid 13a, 13b seal and all can relatively rotate between rotary kiln 12 and two end cap 13a, 13b, and end cap 13a is provided with heat carrier import
14 and high-temperature flue gas outlet 11, end cap 13b be provided with cooling wind inlet 15, cooling wind inlet 15 connect aerator 50, rotary kiln 12
Cooling wind inlet 15 1 side is provided with heating medium outlet 16；The heat load that heat carrier import 14 and heating medium outlet 16 are formed
Body conveying direction is in opposite direction with the flow of flue gas of cooling wind inlet 15, high-temperature flue gas outlet 11 formation；Chiller 10 runs
Time rotary kiln 12 constantly overturn under the drive of device for revolving and driving, enter the revolution of downward-sloping setting from heat carrier import 14
High-temp solid heat carrier 60 in kiln 12 synchronizes upset and moves to heating medium outlet 16, in the turning course of rotary kiln 12
Both sides end cap 13a, 13b transfixion, cooling wind is blown out in rotary kiln 12 from cooling wind inlet 15 by aerator 50, and cooling wind exists
Clash into the heat simultaneously absorbing high-temp solid heat carrier 60 in rotary kiln 12 with rotary kiln inwall, carry on the one hand to high-temp solid heat
On the other hand body 60 cooling produces high-temperature flue gas, and the high-temperature flue gas of generation is through high-temperature flue gas outlet 11 discharge rotary kiln 12 and passes through
Flue is entered waste heat boiler 20 by gas approach 21 and carries out UTILIZATION OF VESIDUAL HEAT IN.But owing to cooling wind is only from the cooling wind inlet of end
15 enter in rotary kiln 12, and its intake is limited, and the distribution flowing that cooling wind is in rotary kiln 12 is uneven, thus it exists
Insufficient, the incomplete problem of Btu utilization to the cooling of high-temp solid heat carrier.In Fig. 1,23 is the main steaming of waste heat boiler 20
Vapor outlet, 24 is the admission port of waste heat boiler 20.
Summary of the invention
For the problems referred to above, present invention provide for the chiller of solid thermal carriers bootstrap system, it can solve
Certainly high-temp solid heat carrier is cooled insufficient problem by existing chiller.
Its technical scheme is, for the chiller of solid thermal carriers bootstrap system, it includes rotary kiln, described time
The two ends of rotary kiln are passed through end cap seal respectively and all can relatively rotate between rotary kiln and described two end cap, the described end cap at two ends
In a side end cap be provided with heat carrier import and described high-temperature flue gas outlet, opposite side end cap be provided with cooling wind inlet, described cooling
Wind inlet connects aerator, described rotary kiln is provided with heating medium outlet near described cooling wind inlet one side, its feature
Being: the periphery of described rotary kiln in a row offers some circumferentially distributed fresh air inlets, described rotary kiln periphery is also positioned at every
One position discharging into air holes is mounted on can phase between circular air inlet storehouse, and described circular air inlet storehouse and described rotary kiln
To rotation, described circular air inlet storehouse is connected with cooling wind, and the exhaust passage in every described circular air inlet storehouse together is all towards described rotary kiln
The one of upper correspondence discharges into air holes.
Further, it is rotatably connected by rolling bearing between described circular air inlet storehouse and described rotary kiln periphery.
Further, the heat carrier conveying direction that described heat carrier import and heating medium outlet are formed enters with described cooling wind
The flow of flue gas that mouth, high-temperature flue gas go out interruption-forming is in opposite direction.
Further, described heating medium outlet is provided with several, and several heating medium outlets described are evenly arranged in
Described rotary kiln is on the periphery of the end of described cooling wind inlet side.
Further, described rotary kiln from described heat carrier import to the downward-sloping layout of heating medium outlet.
Further, the outlet of described high-temperature flue gas is arranged at the top of described heat carrier import.
The beneficial effects of the present invention is: it by a row offering some circumferentially distributed air intakes in the periphery of rotary kiln
Hole, simultaneously rotary kiln periphery be positioned at each position discharging into air holes and be provided with circular air inlet storehouse the most rotatably, and
And the exhaust passage in circular air inlet storehouse is towards the fresh air inlet on rotary kiln, therefore cooling wind is except entering from the cooling wind inlet of existing end
Enter rotary kiln to be entered by the some fresh air inlets on supplying air bin and the rotary kiln corresponding with supplying air bin, can either ensure into
Cool down the intake of wind in entering rotary kiln, in rotary kiln can be strengthened again, cool down the flow perturbation of wind so that two-way cooling wind energy
Common carry out sufficient heat exchange with high-temp solid heat carrier, the solid thermal carriers of promotion high temperature cool and heat returns
Receive, and rotary kiln length can be reduced, reduce the manufacturing cost of rotary kiln.
