Testing device for simulating calcining and cooling of cement clinker

Abstract

The invention discloses a cement production test device, which is a test device for reducing pollution and simulating calcining and cooling of cement clinker. The invention provides a test device for simulating calcining and cooling of cement clinker, which can be close to the actual production condition, the test device comprises an air shaft, a discharge chute, an exhaust fan and a calcining furnace, the discharge turnover grate is of a breathable structure, the wall of the air shaft is provided with an exhaust opening, the exhaust opening is connected with the exhaust fan, and the calcining furnace is connected with the discharge chute. Due to the fact that the internal air purifier is additionally arranged, carbon dioxide and oxynitride produced in the coal calcination process are reduced, and environmental pollution is helped. The air shaft and the unloading turnover grate are adopted to simulate the grate cooler in actual production, so that samples can reach or approach the actual production condition, and more accurate data can be obtained for the actual production; therefore, the problem that the difference between the cooling process and actual production is too large is solved, the cooling process is controlled, the grate cooler is simulated for cooling, and the production guiding effect is achieved; the problem that a large number of samples are difficult to cool is solved.

Description

technical field [0001] The invention relates to the technical field of cement production test, in particular to a test device for simulating the calcination and cooling of cement clinker. Background technique [0002] Burnability refers to the difficulty of calcining cement raw meal to form clinker. This degree directly affects the quality and production cost of cement clinker. Section 8.4 of JC / T735-2005 "Test Method for Burnability of Raw Cement Meal" stipulates that the sample is taken out immediately after calcination and placed in the air to cool to room temperature naturally. At this time, the temperature of the sample is as high as 1300℃-1400℃; When the calcined sample is about 5kg each time, the cooling is usually carried out by a fan or placed in the air for natural cooling, so that the sample cannot meet the requirements of simulated production; in actual production, the cement clinker is directly fed into the grate cooler drum after calcination. Air cooling to a...
