Abstract

The invention discloses a vertical-type spiral particle waste heat recycling device and method for sintering waste heat generation. A device body is sequentially provided with a prestoring segment, a chute segment, a cooling segment and a lower conical segment from top to bottom. The device body is internally provided with an air supply body. The air supply body is a cylinder and is hollow. The top of the air supply body is provided with a pointed cone. The upper portion of the air supply body is provided with four cross-shaped supporting rods. The outer ends of the four supporting rods are fixedly connected with the chute segment. A heat exchange cavity is formed between the air supply body and a tank body of the cooling segment. The outer side of the middle of the air supply body is provided with a spiral discharging channel. The periphery of the upper portion of the spiral discharging channel is connected with the cooling segment. The lower portion of the air supply body is provided with an upward-inclined cross-shaped air channel. The cross-shaped air channel is connected with the lower portion of the lower conical segment. The bottom of the lower conical segment is provided with a bulkhead gate. A closed-type vibrating feeder is arranged below the bulkhead gate. The vertical-type spiral particle waste heat recycling device meets the specific requirement of sintering ore for a cooling device and is high in controllability, the service life of the vertical-type spiral particle waste heat recycling device is prolonged, gas resistance is reduced, flow and temperature uniformity are improved, and the waste heat utilization rate is improved.

Description

technical field [0001] The invention relates to a vertical spiral granule waste heat recovery device and method thereof for sintering waste heat power generation, in particular to a sinter vertical spiral granule waste heat recovery device and method in the fields of metallurgy and iron and steel industries. Background technique [0002] Sensible heat resources of sinter ore in the sintering process account for about 70% of the total waste heat resources in the sintering process, and improving the recovery and utilization rate of waste heat is the main direction of the recovery and utilization of waste heat in sintering. At present, the widely used ring or belt coolers have the following insurmountable disadvantages in the recovery and utilization of sensible heat: [0003] (1) High air leakage rate of cooling equipment [0004] The size of the gap at the air leakage site and the pressure difference inside and outside are the main factors affecting the air leakage rate. Am...
