Abstract

The invention discloses a high-activity 99-grade calcium oxide electric burning furnace kiln and a calcining method, which aim to solve the problems that calcium oxide calcination cannot reach to double high quality with high purity and high activity, and a calcium oxide product cannot meet the high-end requirement of the market. The high-activity 99-grade calcium oxide electric burning furnace kiln comprises a kiln body, and a kiln car movably arranged in the kiln car, wherein calcite form blocks are stacked on the kiln car; a kiln door is arranged on the kiln body; electric heating wires arearranged on an inner wall of the kiln body and the inner surface of the kiln door; an air inlet hole is formed in the kiln car; one end of the air inlet hole is communicated with an inner chamber ofthe kiln body; the other end of the air inlet hole is connected with an air inlet mechanism; a temperature detector and a pressure detector are arranged in the inner chamber of the kiln body; the airinlet mechanism comprises an air storage tank, an electromagnetic valve, a flow detector and a controller; an air inlet pipe is arranged between the air storage tank and the air inlet hole; the electromagnetic valve and the flow detector are arranged on the air inlet pipe; the electric heating wires, the temperature detector, the pressure detector, the electromagnetic valve and the flow detector are electrically connected onto the controller.

Description

technical field [0001] The invention relates to calcium oxide calcining technology, more specifically, it relates to a high-activity 99-grade calcium oxide electric firing kiln and a calcining method. Background technique [0002] my country is a big producer of calcium oxide, but due to backward technology, the field of high-purity and highly active calcium oxide cannot meet high-end standards. Disadvantages of the traditional production process: Most of the products with high activity adopt ultra-high temperature and short calcination time. Although the activity is improved, the calcium oxide content is significantly reduced; high-purity calcium oxide is calcined at high temperature for a long time, the purity is improved, but the activity is significantly decreased. . Traditional production techniques cannot produce double-high products, and cannot meet the high-end requirements required by the market. Contents of the invention [0003] The present invention overcom...
