It is simulated test below:
This utility model feeding zone grate plate to the production line grate-cooler before transformation, carry out the numerical simulation in flow field, obtain the air-flow muzzle velocity by grate plate and the pressure loss, and it has been carried out the improvement of structure, analog data after being improved, this result has reference for appropriate design with type grate-cooler grate plate structure, optimization grate-cooler air flow field, reinforcement gas-solid heat exchange, also functions to the indirect effect of energy-saving and emission-reduction, has certain society and economic worth.
Concrete numerical simulation scheme of the present utility model is as follows:
Region, grate-cooler hot junction is the key position that grate-cooler works, and the bed of material is thick herein, temperature is high, and grog plays when high pressure cooling air from bottom to top permeates red heat deep bed sintering strong quenching effect, and this is significant with recovery high temperature air to improving manufacture of cement quality.Wherein, in high-temperature region, grate-cooler mid portion and two side portions are respectively adopted independent blower fan and grog are cooled down, and are conducive to the adjustment of control system, thus protecting grate-cooler both sides not by high temperature, minimizing accident occurs.
Grate plate interior flow field relevant information is simulated as follows with ANSYSFluent:
(1) having 45 wallboards, wherein both sides have 10, each grate plate inlet-duct area 31250mm2；
(2) centre blower fan number is 5709, flow 17280m3/h, measures cooling air inlet pressure 111687.3pa, aperture 100, measures temperature 20 DEG C；
(3) both sides blower fan number is 5710, flow 13200m3/h, measures cooling air inlet pressure 113013.7pa, aperture 100；Measure temperature 26 DEG C；
(4) ambient pressure 100733pa.
(5) boundary condition is set to, and entry condition is speed entrance, and exit condition is free export.Middle grate plate inlet velocity is 4.34m/s, and both sides grate plate inlet velocity is 11.59m/s.
Simulating the pressure cloud atlas that obtains of grate plate interior flow field it can be seen that air is through grate plate from ANSYSFluent, form a higher-pressure region in bosom position, correspondingly, by speed cloud atlas, the speed herein exported is relatively low, and both are consistent；Additionally by Fluent result of calculation, the speed that the velocity magnitude distribution of each outlet totally presents such as several second outlet of figure Far Left and the right is maximum, and the feature that second left muzzle velocity is minimum, this is also consistent with the above；Meanwhile, there is a low-pressure area at each exit position place of grate plate.Before improving, numerical simulation data result is as shown in table 1.
Table 1 improves front numerical simulation data result
As can be seen from the above table; middle grate plate air outlet slit speed is less; and both sides grate plate air outlet slit speed is relatively large; forming the feature of " both sides wind speed is big; middle wind speed is little ", both sides grog will not be piled up, so as to quickly cool down; strengthen gas-solid heat exchange, to a certain extent also protection grate-cooler both sides will not heating temperature too high；Analyzing from pressure aspect, it can be seen that air is far longer than through middle grate plate through the droop loss of both sides grate plate, this is due to the higher reason of both sides grate plate air intlet velocity ratio.Also find out that both outlet pressures are all more or less the same with ambient pressure 100733pa, form tiny structure.
After improvement, numerical simulation data result is as shown in table 2.
Numerical simulation data result after table 2 improvement
Compare from table 2 and table 1 and can be seen that, grate plate muzzle velocity has had raising, 2 times that are about improving front velocity magnitude more, 15.74m/s is brought up to respectively from 7.44m/s, bringing up to 41.93m/s from 18.05m/s, the latter's muzzle velocity size is more considerable, the gas-solid heat exchange in region, blanking hot junction of the grate plate structural strengthening after improvement, this has quickly cooled down greater significance for the grog in this district, is conducive to producing high-quality cement products.The pressure loss also reduces accordingly simultaneously, and particularly the pressure drop of grate plate two side portions reduces to 4794.55pa from 5622pa, and amplitude is relatively big, and this advantageously reduces the power consumption of cooling blower, has certain economic worth.
The grate plate structure in certain production line grate-cooler blanking hot junction, cement plant has mainly been carried out numerical simulation study by this utility model, draw the cooling air flow field simulation result through grate plate, and this region grate plate structure has been improved, obtain the emulation flow field result of optimization, result shows that droop loss and muzzle velocity have all had good improvement, this specifies the direction that grate plate structure is improved, and has reference.
