Description
Technical field
The utility model relates to a kind of ventilation terminal, relates in particular to a kind of ventilation terminal for vertical cool furnace.
Background technology
The material of heat (as red coke, heat sinter, the white lime that burns till etc.) is when in vertical cool furnace, free-falling is cooling, need ventilation terminal that refrigerating gas is imported and derived equably at vertical cool furnace inner bottom part as far as possible from vertical cool furnace is outside, refrigerating gas fully contacts to be heated at furnace bottom and hot material and rises until furnace roof is discharged, thereby reach refrigerating gas, fully contact with hot material, improve the object of heat exchanger effectiveness.
Because ventilation terminal need to occupy certain area and volume in shaft (tower) furnace, if therefore ventilation terminal arranges unreasonablely, in cooling procedure, will affect the descending smoothly of material.Therefore, this ventilation terminal for vertical cool furnace is except will make cold gas physical efficiency be evenly distributed at furnace bottom as far as possible, also should reduce the impact that material is declined smoothly simultaneously as far as possible, and meeting under above-mentioned requirements, meet structure simple as much as possible, weight is lighter, and the life-span is longer, is more conducive to the requirements such as maintenance.
Conventional ventilation terminal at present, as used the ventilation terminal in the vertical cool furnace such as many limekilns and dry coke quenching, comprise following structure: center is provided with blast cap, by four rectangle wind-guiding beams, be supported on stove center, refrigerating gas enters ventilation terminal by wind-guiding beam, and there is a umbrella hat blast cap top, prevent that material from falling into, some air draft shutters are arranged at umbrella hat bottom, and refrigerating gas enters in vertical cool furnace by shutter, thus the material of central area in cool furnace.In addition, in order to increase stove inward flange gas flow, between the cone bucket shape furnace shell of vertical cool furnace bottom and its abrasion-proof backing block, leave certain gap, refrigerating gas enters in stove from this gap, then on edge, furnace wall, rise, thus near material cool furnace inner rim.
The ventilation terminal of this form is applied in a lot of vertical cool furnace at home, but there is certain shortcoming:
(1) for deriving the furnace shell of edge refrigerating gas and the interstitial structure that liner plate forms, cause the installation of liner plate to have certain difficulty, and furnace bottom cloth wind is even not;
(2) four wind-guiding beams and blast cap horizontal projected area are larger, have accounted for the larger proportion of vertical cool furnace cross-sectional area, and therefore " scaffold " phenomenon occurs sometimes, affect material descending smoothly;
(3) weight of equipment is larger.
