Embodiment Construction

[0031] Figure 1-Figure 7 It is a specific embodiment of the present invention.

[0032] The present invention includes an active coke inlet 1, an overhead hopper 2, a coke guide plate 3, a first-stage lower coke tube 4, a second-stage lower coke tube 5, a flue gas outlet 6, a third-stage lower coke tube 7, an active coke accumulation surface 8, and Ammonia tube 9, lower coke guide 10, coke removal device 11, flue gas inlet 12, coke removal port 13, ammonia injection port 14, coke guide perforated plate 15, coke collection perforated plate 16, coke guide right-angle tube 17, compressed air Take over 18.

[0033] The active coke is fed into the overhead bin 2 from the active coke inlet 1. Two coke guide plates 3 are designed in the top bin 2. The angle between the coke guide plates 3 is 60°. The active coke relies on its own gravity to move along the coke guide plate. 3 Evenly distributed to the left and right sides of the overhead bin 2. Nine first-stage lower coke tubes 4 ...

Abstract

The invention provides a sintering and pelletizing fume absorption and blanking device and belongs to the technical field of sintering and pelletizing fume treatment in the iron and steel industry. The device comprises an activated coke feed port (1), a top bin (2), a coke guide plate (3), a first stage coke blanking pipe (4), a second stage coke blanking pipe (5), a fume outlet (6), a third stage coke blanking pipe (7), an activated coke accumulation surface (8), an ammonia spraying pipe (9), a coke blanking guide device (10), a coke discharging device (11), a fume inlet (12), a coke discharging port (13), an ammonia spraying port (14), a coke guide porous plate (15), a coke collecting porous plate (16), a coke guide quadrature tube (17) and a compressed air connection tube (18). The sintering and pelletizing fume absorption and blanking device has the advantages that a simple and reliable sintering and pelletizing fume absorption tower is used and uniform activated coke blanking is realized, the fume, the activated coke and ammonia are uniformly distributed in the absorption tower, desulfurization, denitration and de-dioxin functions are realized on the fume, the device is adapted to fume amount and SO2 concentration fluctuation, and the system installation is reliable.

Description

technical field [0001] The invention belongs to the technical field of sintering pellet flue gas treatment in the iron and steel industry, and in particular provides a sintering pellet flue gas adsorption and feeding device, which is a simple and reliable sintering pellet flue gas active coke adsorption tower and active coke The uniform feeding device has the functions of desulfurization, denitrification, and dioxin removal for the flue gas of sintering pellets, and can adapt to flue gas flow and SO 2 Concentration fluctuations. Background technique [0002] During the production of sintered pellets, a large amount of SO containing 2 , NOx, dioxin and heavy metal flue gas, usually producing 1t of sinter or 1t of pellets will produce 4000m 3 ~6000m 3 The flue gas directly discharged will cause serious pollution to the environment. The new national flue gas emission standard for sintering pellets has been implemented, and the NOx and dioxin emission limits are clarified. T...
