The invention discloses a converter
smoke radiation type
waste heat boiler
recovery system, comprising a three-way valve, a
settling chamber, a water-spraying cooling device, a
radiation type waste hat boiler and a heat accumulator. When
oxygen content of
smoke reaches the standard, the three-way valve opens a gate communicated with the
settling chamber, high temperature
smoke after being subjected to dust removal by virtue of the
settling chamber is fed into the
radiation type
waste heat boiler, heat exchange is carried out by virtue of a
smoke flow equalizing chamber, a water-cooling radiation heat exchange chamber, an intermediate
settling chamber of a boiler and a
convection heat exchange chamber, dust content and temperature of the smoke are greatly reduced, then the smoke is fed into a dust remover to remove dust and then is recovered; when the
oxygen content of the smoke exceeds standard, the high-temperature smoke is directly subjected to water spraying and cooling by virtue of the water-spraying cooling device, the smoke is fed into the dust remover to remove dust and then is directly discharged. Clearance type steam generated by the
waste heat boiler enters into the heat accumulator to be subjected to
pressure stabilization, so as to be changed into continuous steam, and the continuous steam is applicable to production and power generation. The converter smoke radiation type waste heat boiler
recovery system disclosed by the invention can fully recover heat of converter smoke, the recovered steam quantity is increased by more than 25%, dust removal
water consumption is greatly reduced, and the
system disclosed by the invention can run stably and reliably.
