Description

Technical Field

[0001] The utility model belongs to the technical field of lime production, in particular to an exhaust device for lime calcining. Background Art

[0002] Lime is an air-hardening inorganic cementitious material with calcium oxide as the main component. Lime is a product with high calcium carbonate content such as limestone, dolomite, chalk, and shells, which is calcined at 900 to 1100°C. The main component of limestone is calcium carbonate. Lime and limestone are raw materials used in large quantities in building materials and industry. Limestone can be directly processed into stone and burned into quicklime. Quicklime CaO absorbs moisture or adds water to become slaked lime. The main component of slaked lime is Ca(OH)2, which can be called calcium hydroxide. Slaked lime is prepared into lime slurry, lime paste, etc., and is used as a coating material and brick and tile adhesive. Lime is produced by calcining limestone. During the calcination process, limestone decomposes, and the fuel and limestone produce flue gas together. Direct discharge will cause pollution, so an exhaust device is required for exhaust. However, it still has the following disadvantages in actual use:

[0003] The exhaust device of lime calcination directly uses the exhaust device to filter and then discharge during the exhaust process. During the lime calcination process, all the dust is deposited in the filter element, resulting in a high efficiency of filter element failure and a high cost of using the exhaust device;

[0004] During the exhaust process of the exhaust device for lime calcination, the filter element needs to be disassembled and cleaned after being used for a certain period of time. The cleaning requires a lot of manpower, and there is a lot of dust during the operation, which has a great impact on the health of the operators. Utility Model Content

During operation, after the water falls on the filter element, it is rinsed when passing through the filter element. The rinsed water falls into the top cavity outside the concentration port and is output through the output pipe, making it more convenient to clean the filter element of the exhaust device.
