Embodiment

[0033] In April 2021, in order to change the current 3# titanium slag electric furnace gas purification system dust discharge dust, the titanium smelter carried out the 3# titanium slag electric furnace gas gas purification system dust discharge and dust control transformation work, the transformation was completed in July, and it was put into operation In 4 months, the newly designed anti-dust and ash unloading device has achieved remarkable results, no large dust has occurred at the ash unloading port, and observation and maintenance are very convenient, which ensures the ash unloading and normal operation of the dust collector in the gas purification system of the 3# titanium slag electric furnace The operation ensures the production capacity of the titanium slag electric furnace.

Abstract

The invention relates to a device used for preventing dust raising during ash discharging of a dust removal system of a titanium slag smelting furnace, and belongs to the technical field of titanium slag smelting. The device comprises a movable ash discharge pipe (6) and a lifting device (4), the movable ash discharge pipe (6) is arranged on a fixed ash discharge pipe (2) in a sleeving manner, and the lifting device (4) can enable the movable ash discharge pipe (6) to move up and down along the axis of the fixed ash discharge pipe (2). According to the device, the movable ash discharge pipe (6) is arranged on the fixed ash discharge pipe (2) in the sleeving manner, the movable ash discharge pipe (6) moves up and down along the axis of the fixed ash discharge pipe (2) through the lifting device (4), a pipe opening can descend by means of movement of the movable ash discharge pipe (6), and therefore the fall of dedusting ash is reduced, and raising dust is reduced. The problems that the fall of dedusting ash cannot be adjusted during existing fixed pipe ash discharge, the ash discharging working condition is poor due to reentrainment of dust, and harm is large are solved.

Description

technical field [0001] The invention relates to a device for preventing ash discharge and dust raising in a dust removal system of a titanium slag smelting furnace, belonging to the technical field of titanium slag smelting. Background technique [0002] Most of the smelting industry uses dust removal fans to collect the dust generated by smelting in the form of negative pressure. The collected dust must be discharged regularly to ensure the normal operation of the environmental protection dust removal fan. A large amount of high-temperature metal-containing particles will be generated when the dust is discharged. Secondary dust emission seriously damages the health of workers and pollutes the air environment, and it is very difficult to control the secondary dust emission. In the prior art, there is a fixed ash discharge pipe connected to the lower end of the ash bin, so that the dust removal ash vertically falls about 3000mm from the ground. Unload it into the body of the...
