Steelmaking slag stewing steam recycling equipment

The invention discloses steelmaking slag stewing steam recycling equipment, which comprises a steam pipeline, wherein a steam filter is arranged on the steam pipeline; the steam pipeline is communicated with a steam-water heat exchanger; the steam-water heat exchanger is connected with a water-water heat exchanger through a first water outlet pipe and a first water return pipe; the water-water heat exchanger is connected with a heating system through a second water outlet pipe and a second water return pipe; a first circulating pump is arranged on the first water outlet pipe; and a second circulating pump is arranged on the second water return pipe. By adopting the steam recycling equipment, heat of slag stewing steam can be recycled for supplying heat to heating equipment, the urban heat island effect is not aggravated when low-temperature slag stewing steam is exhausted into the atmosphere, and impurities in the slag stewing steam can be filtered while heat of the slag stewing steam is recycled, so that the impurity content of the slag stewing steam is reduced, and the influence of the emission of the slag stewing steam on the air quality is lowered.
