Embodiment Construction
[0020] The present invention is further described in conjunction with the following examples.
[0021] A specific embodiment of the present invention applicable to the converter slag cooling waste heat utilization device, such as figure 1 As shown, it includes a grate cooler, four atomizing nozzles and a pressurizing device that drives the atomizing nozzles to spray. Specifically, the pressurizing device includes an air compressor 33, an air filter 34, an air flow meter 35, a water pump 31 and Water flow meter 32, water pump 31 links to each other with water flow meter 32; Air compressor 33 is connected with air filter 34 by trachea, and air filter 34 is connected with air flow meter 35; Water flow meter 32 and air flow meter 35 respectively connect high pressure Water and air are connected to the atomizing nozzles through water pipes and air pipes. Of course, the four atomizing nozzles can be shared or a pressurizing device can be selected separately, which only needs to be s...

The invention relates to the technical field of slag waste heat utilization devices, in particular to a waste heat utilization device suitable for cooling of converter slag. The device comprises a grate cooler, four atomizing nozzles, and a pressurizing device for driving the atomizing nozzles to carry out spray-drying. The four atomizing nozzles are arranged for heat exchange, compared with coldair heat exchange, the heat exchange coefficient between sprayed mist and the slag can be greatly increased through sprayed mist heat exchange, and the heat exchange effect is greatly improved. In addition, the four atomizing nozzles are located on the same plane, the opposite atomizing nozzles are arranged in a staggered manner, under drive of the pressurizing device, airflow rising in a convolution manner can be effectively formed, the disturbance of the airflow can be enhanced, the path can be lengthened, the stay time can be prolonged, thus heat exchange is promoted, and the problem that formerly, the waste heat utilization coefficient is low is solved.
Description
technical field [0001] The invention relates to the technical field of slag waste heat utilization devices, in particular to a waste heat utilization device suitable for converter slag cooling. Background technique [0002] At present, there are many types of steelmaking furnaces in my country, such as converters and electric furnaces. Among them, the furnace body of the converter is made of steel plate, which is cylindrical and lined with refractory materials. It is heated by chemical reaction heat during blowing and does not require external heating sources. It is the most important steelmaking equipment. At present, in my country's iron and steel industry, the furnace type of steelmaking furnace is the most widely used converter. Generally, the temperature of converter slag is as high as 1200°C. If this part of heat energy can be effectively utilized, the total energy consumption of steelmaking will be greatly saved, and the work of energy conservation and emission reduc...
