The invention discloses a solid-liquid direct heat conduction reinforced sintering waste heat tank type recovery system, comprising a waste heat recovery tank. The waste heat recovery tank is provided with a pre-storage section and a cooling section; the bottom of the cooling section is provided with an air distribution device; the top of the pre-storage section is provided with a sintered ore inlet; the bottom of the cooling section is provided with a discharge port; a partition wall is vertically arranged in the pre-storage section and the cooling section; and a tank wall water pipe network is arranged on the inner walls of the pre-storage section and the cooling section. Through the arrangement of the partition wall and the tank wall water pipe network, the sintering waste heat tank type recovery system recovers heat of particles on the tank wall and the middle part which do not fully exchange heat with cold air, and the heat enters the medium-pressure end of the steam turbine for two-section type steam power generation, so that the power generation amount of a steam turbine is increased. The effects that gas segregation in the tank body is weakened, the downward moving speed difference of the particles is reduced, the particles evenly move downwards, and the heat loss is small are achieved. The waste heat recovery efficiency and the waste heat utilization rate are further improved on the existing basis.
Description
technical field [0001] The invention relates to the technical field of metallurgical waste heat recovery, in particular to a sintering waste heat tank-type recovery system and device which add a partition wall and an outer wall surface cooling pipe network. Background technique [0002] At present, annular coolers or traditional vertical tank equipment are generally used to cool sintered ore, but most of the settings of annular coolers are for the cooling of sintered ore, and the large amount of heat carried by sintered ore has not been recovered efficiently, while the traditional vertical vertical tank Because the tank only recovers the sensible heat of sinter by inputting cold air, and the gas segregation in the tank affects the movement of particles, so more than 20% of the sensible heat of sinter has not been recovered. [0003] At present, the main problems of the traditional vertical tank waste heat recovery device are as follows: [0004] (1) The segregation of the c...
