AI Technical Summary

Technical Problem

In existing technologies, activated carbon adsorption boxes need to be replaced frequently, resulting in high costs and inconvenient handling.

Method used

A flue gas solid-gas separation device is adopted, which uses an adsorbent made of sawdust, activated carbon and bentonite to absorb oily particulate dust impurities in high-temperature industrial flue gas. The adsorbent is then processed by a waste heat recovery and drying device to achieve the reuse of the dust impurities.

Benefits of technology

It reduces the consumption of activated carbon during desulfurization and denitrification, improves treatment efficiency, avoids energy waste, and enables the reuse of floating dust and impurities.

Abstract

本发明公开了一种高温工业烟气排放脱硫脱硝处理系统，涉及烟气处理技术领域。本发明包括烟气排放管道，烟气排放管道通过一一进两出阀A连通有一烟气固气分离装置和一余热回收装置；余热回收装置的排气端还连通有一烘干装置，烘干装置用于对烟气固气分离装置分离得到的固废物进行干燥；烘干装置和烟气固气分离装置的排气端均与一脱硫脱硝反应装置连通，脱硫脱硝反应装置的排气端还连通有一气体检测装置。本发明将高温工业烟气通入到烟气固气分离装置内，利用吸附物质对化石能源燃烧产生的含有的油性颗粒等浮尘杂质进行吸收；同时先祛除后在进行烟气的脱硫脱硝，降低脱硫脱硝过程中脱硫脱硝液的消耗，并同步提高硫脱硝液的处理效率。
