Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] see Figure 1-5 As shown, a sintered ore distribution and air locking device of a cooling machine includes a sintered hot ore cooler 1. The sintered hot ore cooler has a shell 101, and the feed port on the upper side of the shell has a sintered ore material The material distribution and air lock device 11. There is a horizontal cooling section 102 in the shell of the sintered hot ore cooler, which communicates with the sintered ore material distribution and air lock device 11 through the material discharge port 104; the cooling section is provided with a horizontal The conveying device 105, the material discharge port 104 discharges the mineral material onto the horizontal con...

Abstract

The invention discloses a system for cooling heat ore deposits and recycling waste heat. The system comprises a sintered heat ore cooler, wherein a perpendicular material pre-storage section of the sintered heat ore cooler is equipped with a sintered ore distributing and air-locking device; a horizontal cooling section which communicates with the material pre-storage section is arranged in the sintered heat ore cooler; the cooling section is equipped with a cooler trolley; the bottom of the cooling section is provided with a sectional air supply system for supplying air through an air blower;the upper end of the cooling section is integrated with a waste heat boiler which utilizes waste heat generated in a heat ore deposit cooling process to generate power; the waste heat boiler and the sintered heat ore cooler are connected with a dust remover through a low-temperature flue gas pipeline; a flue gas outlet of the dust remover is connected with an inlet of an induced draft fan; an outlet of the induced draft fan is connected with a flue gas recycling pipeline; and the flue gas recycling pipeline is connected with the sectional air supply system. The system radically solves the airleaking problem of an existing equipment system.

Description

technical field [0001] The invention relates to the technical field of hot ore cooling and waste heat recovery, in particular to a hot ore cooling and waste heat recovery system. Background technique [0002] In iron and steel enterprises, the energy consumption of the sintering process is second only to ironmaking, accounting for 10% to 20% of the total energy consumption, and about 30% of the energy is discharged into the atmosphere in the form of hot flue gas through the sintering cooler. be used reasonably. [0003] When the sintering machine is in normal production, the sintered hot ore falls from the tail of the sintering machine, is crushed by a single roll crusher, screened by a hot vibrating screen, and then falls onto the cooling machine trolley through a chute. The sintering process requires a temperature as high as 1200°C. The temperature of the hot sinter at the chute can reach about 800°C, and the heat is mainly radiated outward. The temperature of the materia...
