Abstract

The invention relates to a test device for measuring the permeability of high-temperature porous piled clinker. The device comprises six wind boxes and a charging basket, and is characterized in that the six wind boxes are arranged on the upper surface, the lower surface, the left surface, the right surface, the front surface and the rear surface of a regular hexahedron respectively in an enclosing manner, so as to form a box body with an upper part and a lower part; the charging basket is arranged in the middle of the box body; each wind box is connected with an external ventilation duct; a ball valve, a vortex flowmeter and a capsule pressure gauge are mounted on each ventilation duct; and temperature measuring venturi tubes are arranged on the upper and front wind boxes. The test device has the advantages that the permeability tensor of high-temperature porous piled clinker can be measured; the relation between the permeability and the temperature of piled clinker can be reflected; and different air supply schemes can be realized only by adjusting the on / off of the ball valves, so that the operation is simple and feasible. The test device is particularly suitable for measuring the permeability of high-temperature piled clinker with the characteristics that the temperature is higher than 1000 DEG C, the particle size is as large as centimeter size, and the piling performance, the porous property and the permeability are second order tensor.

Description

technical field [0001] The invention belongs to the field of test equipment, and relates to a test device for measuring the permeability of high-temperature porous clinker accumulation, especially suitable for high-temperature cement accumulation clinker transported on a grate cooler. technical background [0002] Under the background that traditional convection and gas-solid heat transfer theories are difficult to reveal the internal heat transfer law of cement clinker and cannot further improve the heat recovery rate of the grate cooler, considering that the cement clinker has a stacking property, the porous The introduction of percolation heat transfer theory into clinker heat transfer is helpful for in-depth study of heat transfer mechanism. The permeability of cement stacked clinker is a second-order tensor, which is an important parameter in the theory of porous seepage heat transfer. To determine its size and change law with temperature, the nonlinear Darcy equation w...
