Description

Technical Field

[0001] The utility model relates to the technical field of high-titanium slag smelting, in particular to a waste gas treatment device in the process of high-titanium slag smelting. Background Art

[0002] High-titanium slag is the common name for titanium ore enrichment formed through a physical production process. It is a high-titanium dioxide enrichment obtained by melting titanium ore in an electric furnace to separate titanium dioxide and iron in the titanium ore. It is one of the common industrial raw materials. High-titanium slag needs to be processed in a smelting electric furnace during the processing process. The smelting electric furnace is used to ensure the effective processing of high-titanium slag. Electric furnace ironmaking is a non-blast furnace ironmaking method that uses electricity as heating energy.

[0003] The utility model patent with the authorization announcement number CN219624472U discloses a new type of high-titanium slag smelting electric furnace, which includes a furnace body, which is a cylindrical structure, and a furnace cover is clamped on the upper surface of the furnace body, and the furnace cover is a circular ring structure. The left and right sides of the upper surface of the furnace cover are provided with air outlets, and the air outlets are processed by an opening device. The left and right sides of the upper surface of the furnace cover are located on the upper side of the two air outlets. The elbow is a pipe body of a curved structure, and one end of the two elbows is provided with an exhaust device. The utility model can filter and process the gas generated during the processing, avoid the problem that traditional equipment cannot process the flue gas and affects the life and health of the surrounding personnel, improve the environmental protection performance of the equipment, and increase the safety of the equipment during use.

[0004] Although the above utility model can process the flue gas discharged during the processing to prevent the flue gas from affecting the workers, the above utility model directly filters the flue gas discharged from the furnace body. At this time, the temperature of the flue gas is relatively high, and the temperature will affect the form of certain substances contained in the flue gas, resulting in certain substances being unable to be effectively filtered by the filter. In view of this, we propose a waste gas treatment device in the high titanium slag smelting process. Utility Model Content

The gas is filtered by the filter screen 225 before leaving the cooling box 21. Through the above mechanism, the smoke leaving the furnace body 1 can be cooled.

[0028] In this embodiment, the lower surface of the drain pipe 23 and the lower surface of the cooling box 21 are located in the same horizontal plane, and a valve is provided outside the drain pipe 23 to control the drain pipe 23 to discharge sewage and change water.
