The results show that in case of nitrogen as atomization medium, its pressure of 1. 0 MPa, temperature of alloy liquid at 780 ℃, and rate of liquid flow at 0. 8kg/min, the atomization results as required by spray deposition can be obtained.
When the pH value was 9.6, the amount of catalyst used was 50 g, the air flow was 500 L/h and the liquid flow was 8.0 L/h, the treatment capacity of the fluidized-bed reactor in one operating cycle(12 h) was 19.5 mg/g, while the treatment capacity of fixed-bed reactor was 14.4 mg/g.
and under the temperature of 23 ℃, pH value of 11, liquid flow rate of 60L/h, gas flow rate of 160m3/h, revolving speed of 800r/min, the removal ratio from single pass to treat 5000mg/L ammonia contained effluent can reach 82% by using such packed bed;
The power spectrum density analysis indicated that the power distribution frequency range generated because of the liquid flow and the motion of the particles concentrated in 0-10Hz and 30~40Hz in the liquid solid fluidized bed. After the gas entered into the bed, the signal power was signally focused in the 0-15Hz, that was to say that the pressure fluctuation was dominated by air bubbles.
The mathematical model of liquid flow under pipe flow region in reverse jet loop reactor was deduced from equation of twodimension pseudohomogeneous phase,solutions of the model agreed with experimental data.
Heat transfer and liquid flow in a heating wall with thermal diodes – passive solar heating device which absorb and accumulate solar energy and then transport heat preferentially to the inside of a building, has been investigated.
