Problems solved by technology

The investment cost of this process is low, but the air resistance of the metal honeycomb is large, and a large-power induced draft fan needs to be configured, and when the high-temperature pellets are transported on the chain conveyor, the heat of the lower material layer cannot be recovered, and the sensible heat recovery rate is low.

Abstract

The invention discloses a high-temperature pellet sensible heat recycling device and method. Sensible heat recycling of high-temperature pellets is conducted in an airtight device through gas, water sources are not consumed, dust and harmful gas are not generated either, sufficient recycling of sensible heat can be achieved, and the beneficial effects of energy conservation and consumption reducing are achieved.

Description

technical field [0001] The invention relates to a high-temperature pellet sensible heat recovery device and a recovery method. Background technique [0002] At present, there are many ways to recover sensible heat from high-temperature pellets, such as the sensible heat recovery process of the water-cooled beam of the pelletizing shaft furnace, the sensible heat recovery process of the pellet tank type, and the sensible heat recovery process of the closed chain plate machine, etc. The water-cooled beam sensible heat recovery process of the pellet shaft furnace is to change the large and small water beams of the pellet shaft furnace from the forced circulating water cooling to the vaporization cooling method, so that the high-temperature pellets can directly exchange heat with the vaporization cooling beam, and reduce the circulation of water , to produce low-pressure steam. However, the transformation period of the shaft furnace of this process is long, and the heat transfe...
