The invention discloses a low
energy consumption system for purifying and incinerating harmful gases. The low
energy consumption system consists of main body units such as a
waste gas purifying and incinerating unit, a
waste heat recovering unit and a
flue gas treating body unit as well as auxiliary equipment such as fuel equipment,
combustion-supporting air equipment, heat exchange medium equipment and harmful gas adsorbent equipment. According to the low
energy consumption system, due to the adoption of various latest energy-saving
combustion technologies and energy-saving emission-reducing measures, the optimization is carried out from the whole, the problems that energy consumption of a DTO (Direct-Fired
thermal Oxidizer) of a conventional chamber type
waste gas incinerator is over high, RTO (Regenerative Thermal Oxidizing Furnace)
waste gas of a reversed heat accumulation type waste gas incinerator is not completely combusted, a heat accumulator is blocked by dust-containing waste gas and the like are solved and various harmful waste gases can be continuously purified and incinerated at low cost. Due to the adoption of a brand-new heat accumulation
incineration mode, the low energy consumption system has the characteristics that the heat accumulator is easy to clean for avoiding blocking, the harmful waste gases are completely incinerated and discharged after reaching the standard, the energy-saving effect is remarkable and the like. In addition, due to the adoption of measures of selecting an
oxygen-enriched
combustor, matching with
oxygen-enriched and
combustion-supporting air supply equipment, providing hot air for
incineration to support combustion and the like, the consumption of auxiliary fuel can be effectively reduced, the
incineration treatment expenses are reduced and the popularization and the application are facilitated.
