Combustion-supporting device for double-chamber lime kiln and double-chamber lime kiln
The invention provides a combustion-supporting device for a double-chamber lime kiln and the double-chamber lime kiln. The device comprises an air inlet pipe, a combustion fan, a first air conveying pipe, a second air conveying pipe, a third air conveying pipe and a heat exchange mechanism. The air inlet pipe is connected with an inlet of the combustion-supporting fan, an outlet of the combustion-supporting fan is connected with an inlet of the heat exchange mechanism through a first air conveying pipe, the heat exchange mechanism is arranged at a cooling area of the double-hearth lime kiln, and an outlet of the heat exchange mechanism is connected with a combustion-supporting air opening of the double-hearth lime kiln through a second air conveying pipe. The heat exchange mechanism exchanges heat between the combustion-supporting air and lime in the cooling area and conveys the combustion-supporting air subjected to heat exchange and temperature rise to the combustion-supporting air opening; and a chimney outlet of the double-chamber lime kiln is connected with the air inlet pipe through a third air conveying pipe so as to convey flue gas generated by the double-chamber lime kiln to the air inlet pipe. According to the invention, the preheating of combustion-supporting air is realized, the heat consumption of the double-hearth lime kiln is reduced, the heat efficiency of the double-hearth lime kiln during combustion is improved, and the air volume of lime cooling air during cooling of high-temperature lime is reduced.
本发明提供了一种双膛石灰窑用助燃装置及双膛石灰窑。该装置包括：进风管、助燃风机、第一输风管、第二输风管、第三输风管和换热机构；进风管与助燃风机的进口相连接，助燃风机的出口通过第一输风管与换热机构的入口相连接，换热机构设置于双膛石灰窑的冷却区处，换热机构的出口通过第二输风管与双膛石灰窑的助燃风口相连接，换热机构将助燃风与冷却区内的石灰进行换热，将换热升温后的助燃风输送至助燃风口；双膛石灰窑的烟囱出口通过第三输风管与进风管相连接以将双膛石灰窑产生的烟气输送至进风管。本发明实现了助燃风的预热，降低了双膛石灰窑的热耗，提高了双膛石灰窑燃烧时的热效率，减少了对高温石灰冷却时石灰冷却风的风量。
