Abstract

The invention discloses an energy-saving and environment-friendly cupola. By adding equipment such as heat exchangers and dust collectors, the tail gas of the furnace is treated with heat energy recycling, dust removal and desulfurization, etc., so as to achieve energy saving (reduce coke consumption), It also has the effect of reducing pollution emissions (high-temperature gas, SO2, dust). At the same time, due to the use of hot air inlet technology, the furnace temperature is increased, the reject rate of casting products is reduced, and economic benefits are increased.

Description

technical field [0001] The present invention relates to a cupola. Background technique [0002] During the smelting process of the cupola furnace, a reduction reaction will occur, so that the tail gas of the furnace gas will produce about 13% CO. When CO is burned, the flame temperature can reach 2095 ° C, and the calorific value is very high. The cupola currently used is generally exhausted from the furnace gas into the atmosphere through the chimney, or directly cooled with water due to the needs of dust removal equipment, the physical heat and potential chemical heat in the furnace gas tail gas (that is, the heat energy released by CO combustion) Not being exploited. The sum of this part of heat energy is equivalent to 30% of the heat released when the coke used in the production process is burned. If it is not used, it will be wasted in vain. Therefore, the cupola furnace has great potential for energy saving and consumption reduction. At the same time, the dust, sulfi...
