This disclosure relates to the field of high-titanium slag blast furnace smelting technology, and particularly to a method for restoring a high-titanium slag blast furnace after a shutdown. The method includes: reducing the coke load by 13% to 18% 4-5 hours before the shutdown; adding clean coke 3-4 hours before the shutdown, and adjusting the charging system to: a 3-ring ore charging system, with the ore platform's radial angle width ranging from 3° to 4°, the outer coke-ore angle difference ranging from 1.5° to 2°, and the inner ore-coke angle difference ranging from 5.5° to 6°; and controlling the pig iron [Ti] content to 0.15% to 0.20% and the slag binary basicity to 1.04 to 1.08 times the standard basicity starting 1-2 hours before the shutdown. This disclosure allows for rapid restarting of a high-titanium slag blast furnace after a long shutdown.

This utility model relates to the field of drying equipment and provides a hot air drying device for dehydrated vegetables. It includes an outer cylinder and an inner cylinder installed inside the outer cylinder, both with openings at the top. The bottom and sides of the outer cylinder have air inlets and outlets, respectively. A fan structure is installed at the bottom of the inner cylinder. A circulation chamber is provided between the outer and inner cylinders. A first heating grid is located between the inner bottom of the outer cylinder and the inner cylinder, and a second heating grid is located between the inner top of the outer cylinder and the inner cylinder. The top of the outer cylinder has a removable cover, and the bottom of the cover has several trays at different heights. This device effectively solves the problem of uneven hot air distribution in existing drying equipment. The synergistic effect of the inner and outer cylinders ensures that the hot air is evenly distributed within the inner cylinder, avoiding over-drying and scorching of vegetables due to excessively high local temperatures. This not only significantly improves the quality of the dehydrated vegetables but also greatly shortens the drying time and increases drying efficiency.

The invention relates to an adjustable spray type vertical desulfurization waste liquid incinerator with multiple flow guide plates and a waste liquid desulfurization method, by arranging a waste liquid nozzle with an adjustable extending distance and a multi-flow guide plate structure with a partition ventilation rate, the spray position is dynamically adjusted along with the treatment capacity, and the distribution of a flow field in the incinerator is optimized; spray always enters a high-temperature core area; the two layers of guide plates are arranged up and down, the overall ventilation rate is high in front and low in back, small holes in a central area are dense, the ventilation rate is low, airflow is forced to diffuse towards the periphery, and radial mixing is enhanced. According to the vertical desulfurization waste liquid incinerator, the waste liquid evaporation and cracking efficiency is remarkably improved, wall hanging corrosion is reduced, the flue gas retention time is prolonged by 15%-20%, the combustion efficiency is improved by 12%-15%, generation of nitric oxide is reduced, and efficient, stable and environment-friendly operation is achieved.

The utility model relates to the technical field of combustors, and discloses a nozzle structure for a high-efficiency combustor, which comprises a nozzle outer cylinder, an air inlet inner cylinder is arranged in the nozzle outer cylinder, the outer side wall of the air inlet inner cylinder is fixedly connected with a fixed wall, the right side surface of the fixed wall is fixedly connected to the opening at the left end of the nozzle outer cylinder, and the right side surface of the fixed wall is fixedly connected to the opening at the right end of the nozzle outer cylinder. A combustion-supporting gas inlet pipe is embedded in the fixing wall, a through hole is formed in the side surface of the gas inlet inner cylinder, and an igniter is fixedly installed on the right side surface of the gas inlet inner cylinder. By arranging the gas inlet inner cylinder with the surface provided with the through holes, the diameter of the through holes is gradually increased from left to right, gas between the nozzle outer cylinder and the gas inlet inner cylinder can be evenly distributed, combustion-supporting gas is input into the nozzle outer cylinder through the combustion-supporting gas inlet pipe, and the gas and the combustion-supporting gas are mixed in the area between the nozzle outer cylinder and the gas inlet inner cylinder; and under the blocking of the arc-shaped wall on the left side of the annular baffle block, the gas can generate certain rotation, so that the gas and the gas can be more fully mixed.
