This invention discloses a method for preparing an ozone catalyst based on oily iron sludge, comprising: adding polyacrylamide, sintering plant electrostatic precipitator ash, and bentonite to dried and pulverized hot-rolled oily sludge, continuously stirring for a set time to obtain a homogeneous material, drying the homogeneous material to a set moisture content to form granules, and carbonizing the granules to obtain an ozone catalyst; effectively solving the problems of harmlessness, volume reduction, and resource utilization of metallurgical solid waste hot-rolled oily sludge, and innovatively providing a production route for an ozone catalyst with low cost and good catalytic performance.

This utility model relates to the field of mixing technology in sintering plants, and provides a device for automatically adjusting the water supply and preheating the water temperature in a mixer. It includes a preheating water tank, a direct water tank, a heating system, and a control system. The heating system is located inside the preheating water tank and the direct water tank. An upper electric valve connected to the direct water tank is located on the lower side of one end of the preheating water tank. An upper steam heating pipe is horizontally installed inside the preheating water tank. An upper electric steam inlet valve and an upper electric steam outlet valve are installed at the steam inlet and outlet ends of the upper steam heating pipe. An upper electric water inlet valve and a maintenance port are located on the upper side. Water temperature and level detectors A and B for the preheating water tank are installed on the side wall. A lower steam heating pipe is horizontally installed inside the direct water tank. A lower electric steam inlet valve and a lower electric steam outlet valve are installed at the steam inlet and outlet ends of the lower steam heating pipe. Water temperature and level detectors A and B for the direct water tank and a water supply valve are installed on the side wall. The control system includes an automatic water supply control system, a valve opening and closing control system, and a humidity sensor at the mixer's feed inlet.

The present invention relates to a method for supplying raw materials to a sintering plant (20), the method comprising the step of supplying raw materials using a mixed material (7, 8) to facilitate the sintering process with reduced consumption of fossil fuels, the mixed material (7, 8) comprising a granular iron-bearing material (1) and a granular pyrolyzed biomass (2) in a mixed form, the iron-bearing material (1) being preferably iron ore (1) and the pyrolyzed biomass (2) being preferably charcoal (2).
