Description

Technical Field

[0001] This utility model relates to the field of smelting furnace technology, specifically to a water-saving device for reusing cooling water in an industrial silicon smelting furnace. Background Technology

[0002] Industrial silicon is a common industrial raw material. In the smelting of industrial silicon, special industrial silicon smelting furnaces are often used. The raw materials for industrial silicon smelting are usually silica ore or silicon dioxide ore.

[0003] According to patent authorization announcement number CN202020355365.7, a water-saving device for cooling water reuse in industrial silicon smelting furnaces includes a smelting furnace, a multi-stage settling tank, and a cooling tower. The smelting furnace and the multi-stage settling tank are connected by a return water pipe, with a temperature measuring device installed at the furnace outlet on the return water pipe. The smelting furnace and the cooling tower are connected by a cooling water pipe, with a flow regulating valve installed on the cooling water pipe. The multi-stage settling tank and the cooling tower are connected by a water supply pipe, one end of which is connected to the top of the cooling tower. A water pump is installed inside the multi-stage settling tank. The multi-stage settling tank has lower and upper baffles, and a bottom opening / closing plate is installed between every two lower baffles. A handle is installed on the bottom opening / closing plate, and a fixing block is installed between the bottom of the bottom opening / closing plate and the multi-stage settling tank. This device, when used in the industrial production of industrial silicon, reduces the amount of wastewater discharged during the production process to a certain extent, resulting in good economic and social benefits.

[0004] However, in existing wastewater treatment devices for industrial silicon smelting furnaces, the filtered scale accumulates directly on the filter screen when filtering water. This accumulation can easily clog the filter screen, affecting the filtration effect and causing secondary pollution of the wastewater. Additionally, the small contact area between the wastewater and the refrigeration pipes during wastewater cooling reduces the cooling effect. Utility Model Content
