A blast furnace slag flushing water filter

Abstract

The invention relates to a blast furnace flag flashing water filter, and belongs to the technical field of new energy. The blast furnace flag flashing water filter mainly comprises a water inlet tube, wherein the water inlet tube is arranged vertically; the left side of the water inlet tube is communicated with a first slag storage cabin; the right side of the water inlet tube is communicated with a second slag storage cabin; a support rack is mounted on the water inlet tube; a gearbox is arranged on the support rack; the gearbox is provided with a first output shaft, a second output shaft and a third output shaft; the first output shaft is connected with a first sealing plate; the second output shaft is connected with a filtering net rack; the third output shaft is connected with a second sealing plate; the first sealing plate, the filtering net rack and the second sealing plate are all positioned inside the water inlet tube; and slag cleaning holes are formed in the bottoms of both the first slag storage cabin and the second slag storage cabin. Due to design of a completely novel structure, slag in slag flashing water can be filtered, meanwhile the stop time caused by slag cleaning can be greatly shortened, and thus continuous supply of the slag flashing water can be substantially ensured.

Description

technical field [0001] The invention relates to the technical field related to new energy, in particular to a blast furnace slag flushing water filter. Background technique [0002] In the iron and steel smelting process, the high-temperature slag is usually cooled by water flushing slag, so that the high-temperature slag becomes a recyclable raw material. During the slag flushing process, the water absorbs heat and becomes high-temperature slag flushing water. [0003] Using the heat of high-temperature slag-washing water for heating can reduce coal consumption and save water resources, which is a common way to reuse slag-washing water. However, because the slag flushing water contains slag and suspended fine particles, the slag flushing water must be filtered before heat exchange to avoid clogging the heat exchanger. [0004] The currently commonly used filter systems are generally two-stage filter or three-stage filter structure. That is, the slag is filtered through t...

Problems solved by technology

However, manual slag removal generally takes 12 hours or even longer, so there is a disadvantage of intermittent insufficient heating

[0006] For some users who require high heat source continuity, stopping the hot water supply for a long time will cause greater losses
