InactiveCN102382914BReduce dosageReasonable designBlast furnace detailsCooling devicesRefractoryEngineering
The invention discloses a blast furnace superconducting cooling and waste heat power generation system. The system is composed of a blast furnace body (1), a power generation system (12) and a steam utilization device. The system is characterized in that more than one superconducting ring type heat exchange ring (2) is arranged along the side wall of the blast furnace body (1) in a layering and surrounding mode; each superconducting ring type heat exchange ring (2) is provided with a pouring solidification body (10) formed by using wear-resisting thermal-shock-resisting carburizing-resisting elastic castable refractory; each superconducting ring type heat exchange ring (2) is embedded in the inner lining of the side wall of the blast furnace body (1) through the pouring solidification body (10); and the like. According to the invention, hot water subjected to heat exchange is intently led out through the superconducting ring type heat exchange ring and an annular pipeline system corresponding to the superconducting ring type heat exchange ring, thus heat exchange intensity is enlarged, and heat exchange efficiency and cooling efficiency are improved; and the traditional cooling water temperature is improved to 250 DEG C from 40 DEG C, and then the cooling water is overheated to 400 DEG C through applying the superconducting ring type heat exchange ring twice, so that cooling waste heat can be utilized for power generation.

A multi-vortex ratio tornado simulation device
The invention belongs to the field of wind fields, and in particular relates to a multi-eddy current ratio tornado simulation device. A multi-vortex ratio tornado simulation device, comprising a simulator body, the simulator body is provided with deflectors, and the simulator body is also provided with an angle adjustment for adjusting the angle of the deflectors so as to change the swirl ratio mechanism. The beneficial effects of the present invention are: the present invention sets an angle adjustment mechanism for adjusting the angle of the deflector in the simulation device body, and changes the speed direction of the airflow entering the plexiglass cover through the angle adjustment mechanism, thereby changing the vortex ratio of the tornado. The rotation of the angle adjustment mechanism drives the deflector to rotate together, avoiding the complicated steps of adjusting the deflector separately and reducing the error of manual adjustment. The wind speed of the exhaust fan can be measured, the angle scale is set in the arc groove, the inflow angle can be read, and the height of the inflow area is also known, so that the swirl ratio can be calculated, and the replacement of the deflector and the base can also be avoided.
