Abstract

The invention discloses an N-stage stepped sealing and 360-degree flue gas recovery system for a circular cooler trolley. The N-stage stepped sealing and 360-degree flue gas recovery system for the circular cooler trolley comprise connecting beams 108, trolleys 109 are installed between the adjacent connecting beams 108, inner side baffle plates 111 are installed between longitudinal wing plates,located on the inner sides, of the adjacent connecting beams, outer side baffle plates 112 are installed between the longitudinal wing plates, located on the outer sides, of the adjacent connecting beams 108; and the bottom of each inner side baffle plate 111 is connected with an inner side sealing plate 111a used for sealing the inner side of the corresponding trolley 109, the bottom of each outer side baffle plate 112 is connected with an outer side sealing plate 112a used for sealing the outer side of the corresponding trolley 109, and a sealing plate I 108c used for sealing the rear side of the front trolley and a sealing plate II 108d used for sealing the front side of the rear trolley are correspondingly arranged on the bottom surface of each connecting beam 108. According to the N-stage stepped sealing and 360-degree flue gas recovery system for the circular cooler trolley, improving a circular cooler at multiple positions is carried out, rotary sealing of the circular cooler isenhanced, the cold air utilization rate is increased, energy consumption is reduced, graded recycling of flue gas is achieved, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of ironmaking and sintering ring coolers, in particular to an N-level stepped seal and 360-degree flue gas recovery system for a ring cooler trolley. Background technique [0002] In iron and steel production enterprises, sintering is one of the ironmaking production processes. The process is to mix powdered ore powder and coke powder, and then pass them through a sintering machine to make them into blocks of a certain size to facilitate smelting. The cooling of the sintered ore of the sintering machine is mainly realized through the cooling machine. At present, the cooling machine used by the iron and steel enterprises has two forms: the belt cooler and the annular cooler. Annular cooler is the abbreviation of annular cooler. Its function is to effectively cool the sintered hot ore unloaded from the sintering machine. Compared with the belt cooler, the annular cooler has the advantages of less floor space, ...
