The invention relates to a porous internal combustion shaft kiln, which is a porous internal combustion shaft kiln for continuous charging and discharging and is light roasting equipment of magnesite and limestone. Materials are always in a moving state in the kiln body. The porous internal combustion shaft kiln is characterized by being composed of a hopper, a charging seal valve, a kiln body, light roasting holes, internal combustion chambers, a nozzle, a built-in heat exchanger, a discharging machine I, a discharging seal valve, a scale hopper, a discharging machine II, a flue gas / primary air heat exchanger, a dust remover and a flue gas duct. 2-10 light roasting holes and 3-11 internal combustion chambers are arranged inside the kiln body. According to the porous internal combustion shaft kiln, low productivity, high energy consumption and high pollution problems of a reflection shaft kiln and problems of a twin chamber kiln and a sleeve kiln such as large investment, complicated operation, large operation difficulty and the like are solved. The volume of the porous internal combustion shaft kiln is 100-600 m<3>, and production capacity is 80-560 tons / day.
Description
technical field [0001] The invention belongs to a light burning technology of magnesite and limestone materials used in the fields of metallurgy, building materials and chemical industry, and in particular relates to a porous internal combustion type shaft kiln. Background technique [0002] Magnesite and limestone are lightly burned at 900-1000°C to generate active magnesium oxide and calcium oxide. Activated magnesium oxide and calcium oxide are widely used in metallurgy, building materials and chemical industries. At present, the domestic production of activated magnesia kiln mainly adopts reflective shaft kiln, which has problems such as backward technology of reflective shaft kiln, manual feeding and discharging, small volume, low production capacity, high energy consumption, poor product quality, and serious pollution. Local governments are included in the list of high-pollution and high-energy consumption equipment. Domestically produced active lime kilns are mainly...
