Slag washing water filter

Abstract

The invention relates to a slag washing water filter, and belongs to the related technical field of new energy. The slag washing water filter mainly comprises a vertically arranged water inlet pipe; the left side of the water inlet pipe is communicated with a first slag storage bin, and the right side of the water inlet pipe is communicated with a second slag storage bin; a support frame is installed on the upper portion of the water inlet pipe, and a gearbox is arranged on the support frame; 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 filter screen frame, and the third output shaft is connected with a second sealing plate; the first sealing plate, the filter screen frame and the second sealing plate are all located inside the water inlet pipe; filter screens are arranged on the lower portion of the first slag storage bin and the lower portion of the second slag storage bin respectively, and the bottom of the first slag storage bin and the bottom of the second slag storage bin are communicated with the lower portion of the water inlet pipe through transition pipes respectively and provided with skimming holes respectively. According to the slag washing water filter, slag in slag washing water is filtered out, and meanwhile the downtime caused by slag removal is greatly shortened.

Description

technical field [0001] The invention relates to the technical field related to new energy, in particular to a 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 the first-level...

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
