Circular cooler air input system, annular ventiduct and annular liquid flume

Abstract

The invention discloses a ring-cooling machine air intake system which comprises a ring-shaped air duct communicated with a branch air duct; the branch air duct is communicated with a ring-shaped airchannel; in addition, the exit of the ring-shaped air channel is communicated with a trolley blast pipe, while the trolley blast pipe is communicated with a trolley. The ring-shaped air channel consists of a ring-shaped liquid trough and a portal type sealing equipment. The portal type sealing equipment is connected with the trolley blast pipe; a sealing cover plate of portal type sealing equipment is covered on the ring-shaped liquid trough. An inner ring-plate and an outer ring-plate of the portal type wind channel of the portal type sealing equipment extend below the liquid level of the ring-shaped liquid trough; a ring-shaped inner liquid trough and a ring-shaped outer liquid trough of the ring-shaped liquid trough are respectively communicated with a water charging pipe in a high temperature region of the ring-cooling machine, and the water charging pipe is used for injecting the low temperature liquid into the ring-shaped inner liquid trough and a ring-shaped outer liquid trough.The invention also discloses the ring-shaped air channel and the ring-shaped liquid trough. The invention can prevent the hot flue gas from consistently heating part liquid, and prevent the liquid inthe ring-shaped liquid trough in the high temperature region of the ring-cooling machine from vaporizing due to overhigh temperature, so as to ensure the normal operation of the ring-cooling machine.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to an air inlet system, an annular air duct, and an annular liquid tank of an annular cooler. Background technique [0002] In iron and steel smelting, ring coolers are used to cool sintered materials. The ring cooler is in the shape of a ring as a whole, and the sintered material runs in the ring cooler for a week through a trolley to complete cooling and unloading. see figure 1 , is the radial (pointing to the center of the annular cooler) cross-sectional view of the annular cooler 10, the sintered material is laid on the grate plate 12 of the trolley 11, and the trolley 11 rotates at a constant speed around the center of the annular cooler 10. Simultaneously, the cold wind blown by blower (not shown in the figure) enters trolley through grate plate 12 from bottom to top, and after carrying out sufficient heat exchange with the material on grate plate 12, discharges from e...

[0006] see image 3 , is a radial sectional view of the annular air duct of the annular cooler 10, hot flue gas with a certain temperature passes through the annular air duct 33 from bottom to top, and the continuous passage of the hot flue gas will heat the annular air duct liquid tank of the annular water tank 34 The inner ring plate 341 and the outer ring plate 342 of the annular air channel liquid tank, the inner ring plate 341 of the annular air channel liquid tank is on the side closer to the center of the annular cooler 10 relative to the outer ring plate 342 of the annular air channel liquid tank, so that the inside of the annular water tank 34 When the liquid heats up, the liquid will vaporize when it reaches a certain temperature, and the vaporized liquid enters the trolley (not shown in the figure) along with the hot flue gas, so that the dust material sticks to the grate plate (not shown in the figure) of the trolley, affecting The ventilation of the grate plate will also cause the dust material on the lower plate of the trolley (not shown in the figure) to stick to the lower plate, affecting the static sealing of the trolley
