Abstract: A cooperative emission reduction method for sintering using an energy-carrying composite gas is disclosed. A surface of a sintered material is divided into an ignition section, a heat preservation section, a middle section, a flue gas heating section, and a machine tail section from a machine head to a machine tail of a sintering machine; according to flue gas components, temperature characteristics, and heat requirements of different sections, a hot exhaust gas is introduced to the ignition section for ignition, a hot exhaust gas is introduced to the heat preservation section and a hydrogen-rich gas is cascadingly sprayed synchronously, cascaded spraying of water vapor is coupled based on spraying of a hydrogen-rich gas in the middle section, and the high-temperature flue gas in the machine tail section and the flue gas in the ignition section and/or the heat preservation section are circulated to the heating section.

Abstract: The present invention discloses a kind of anti-pollen glasses includes a glass frame and a protection cover, the protection cover is detachably assembled at an outer side of the glass frame and has an accommodation groove adapting to the glass frame, a side wall of the accommodation groove encloses the whole glass frame and forms a protection ring surface, the protection cover is provided with relief windows corresponding to positions of the lenses. The structure of the present invention is simple, a protection cover is added on the basis of regular glasses, and the glasses can be used as the regular glasses after the protection cover is removed. It is convenient for assembling and disassembling, in an environment where anti-pollen is not required, a wearer can easily detach the protection cover to reduce pressure on a face, and can conveniently assemble the protection cover when necessary.
