Problems solved by technology
at P0 3 The faults at the discharge port are mainly due to the high temperature of the steel shell, the deformation and damage of the furnace lining, and the material at P0 3 During the process of internal blanking, the temperature and heat cannot be maintained, resulting in heat energy loss, which prevents the output from being blocked by the blanking connection pipe, increases various production instability factors, and even causes sudden shutdown of the furnace, resulting in huge losses.

Embodiment 1
[0023] Original high temperature separator P0 3 The volume of the lower cone space is 57.73 m 3 , exit stream diversion angle a 1 about 28°. In order to increase the output per unit area and thermal efficiency and reduce wear and tear, the following measures are adopted:
[0024] 1. The double-cone settling chambers with different tapers are superimposed, and the taper of the settling chamber in the upper cone section a 1 About 28°, the taper of the settling chamber in the lower cone section a 2 about 22°. P0 3 The vertical height of the settling chamber in the cone section is extended to more than twice the vertical height of the upper cylindrical settling chamber, and the volume of the cone space is expanded to 60m 3 above.
[0025] 2. The lower part of the settling chamber adopts the same insulating furnace lining as the cone settling chamber, and the vertical height of the pipe is 1.6m, which is equivalent to one-fifth of the height of the upper cone.
[0026] The ...

The invention relates to a P03 discharging device for a high-temperature separator of a gaseous aluminum hydroxide suspension calciner, which comprises a cylindrical settling chamber, an upper conical setting chamber, a lower conical settling chamber and a discharge receiving pipe sequentially from top to bottom. The taper of the upper conical setting chamber ranges from 20 degrees to 28 degrees, the taper of the lower conical settling chamber ranges from 18 degrees to 24 degrees, and the sum of heights of the upper conical setting chamber and the lower conical settling chamber is larger than the height of the cylindrical settling chamber. The discharge receiving pipe is a vertical round pipe, and the outer wall of the discharge receiving pipe is provided with a heat insulation layer. The P03 discharging device is simple in structure, energy-saving and environment-friendly, aluminum hydroxide yield can be increased, and heat loss is reduced.
Description
technical field [0001] The invention relates to a discharge device of a high-temperature separator of an aluminum hydroxide gas-state suspension roasting furnace, specifically a high-temperature separator P0 of an aluminum hydroxide roasting furnace 3 Discharge device. Background technique [0002] Currently, Al(OH) 3 The vapor suspension roaster system is one of the important components of the entire (GSC furnace) roaster project. The high temperature separator P0 3 The discharge port of the high temperature furnace is one of the most important fault locations. Roasting furnace system high temperature separator P0 3 The structure has changed little over the past few decades, and scientific improvement is urgently needed to make it more energy-saving and environmentally friendly. at P0 3 The faults at the discharge port are mainly due to the high temperature of the steel shell, the deformation and damage of the furnace lining, and the material at P0 3 During the proces...
