At present, steel mills on the market can generate a large amount of dust in the process of producing steel, and the dust of special steel mills which rely on recycling waste steel for processing is more, so that air is polluted, workers can generate dust lungs, and the body health of the workers is seriously infringed, and application No. 201921684847.0 designed before us discloses an environment-friendly device for dedusting of the mills, which comprises a box body, and a filtering unit and a spraying unit which are arranged in the box body, wherein the top of the box body is provided with an air inlet which is communicated with the filtering unit, the top of the side wall of the box body is provided with an exhaust pipe, the filtering unit comprises a filter cartridge, a motor, a reciprocating screw rod, an internal thread sleeve and a brush ring, the spraying unit comprises a ring pipe and a circulating pipe, an ultraviolet sterilizing lamp is arranged in the exhaust pipe, the top and the bottom of the inner cavity of the exhaust pipe, the hairbrush ring is driven to move up and down in a matching manner, so that dust on the filter cartridge can be brushed off, the hairbrush ring can be prevented from being stuck on the hairbrush ring due to the fact that the hairbrush ring moves into water, meanwhile, the filter cartridge can be better scrubbed due to the fact that water is stuck on the hairbrush ring, the water stuck on the filter cartridge can better adsorb the dust, and the filtering effect is improved; the ultraviolet germicidal lamp and the partition board are arranged, and the air can be disinfected and sterilized. The device is relatively complex in structure in actual production, can be damaged in a high-temperature environment, needs to consume electric power to maintain long-term operation, and is not high in reliability, so that the dust removing device utilizing the waste heat of the refining furnace is designed.
Stirling (robert stirling, 1790-. Stirling contributes significantly to the development of thermodynamics. His scientific work was primarily a heat engine. The research and development work of the heat engine is the central subject of physics and mechanics in the 18 th century, various heat engines are produced by different times, and the references are continuously taken for each other, so that the advantages and the disadvantages are made up, the heat engine manufacturing industry is vigorous, and the industrial revolution is in the climax period. As heat engines have developed, thermodynamic theory research has advanced to an important position, and many scientists have devoted themselves to the research work of heat engine theory, among which stirling is one of the most well-known. The stirling cycle, which he proposes, is one of the important heat engine cycles, also known as the "stirling heat engine cycle". The circulation is closed, and a gas circulation mode of absorbing heat under constant volume is adopted. The Stirling heat engine utilizing the circulation has many characteristics, such as external combustion or external heat source heating. Because the circulation is closed circulation, the high-pressure gas which is far more than the atmospheric pressure can be adopted for working, so that the power per unit weight of the engine can be improved, and the volume and the weight of the engine can be reduced. When the Stirling heat engine runs reversely, the Stirling heat engine can be used as a refrigerator or a heat pump, and the concept enters the practical research stage in modern times.
