In this paper, the effects of two main factors on dry hydration productions properties of water-lime ratio and stirring speed were studied by using a pint-sized dry hydration equipment. The effect of water-lime ratio and stirring speed on hydration rate were analyzed. Characteristic of temperature rise during hydration procedure was put forward, and the surface structure characteristics and size distribution...
In this paper, Eucalyptus grand is × E.urophylla was pretreated under 100°C steam and boiling water conditions respectively, and then the pretreatment and untreated specimens were dried in a kiln in which the temperature was 65°C and the pressure varied between 0.1MPa and 0.3M Paevery one hour. As a result, we got the conclusions that, both 100°C steam and boiling water pretreatment could reduce wood...
Solar dryer with latent heat storage system was designed in order to solve the problems of continuity of solar drying. The system was used to dry grape. The results of experiment show that the dryer met the requirement of continuous drying. At solar radiation of 600 Wm-2-900 Wm-2 and ambient temperature range of 3542 °C, the solar collector instantaneous thermal efficiency is 56%, the minimum heating...
The experimental research was carried out about process of SO2 removal in flue gas using white lime slurry atomization, and with the method of non-contact on-line measuring for SO2 concentration in riser. The temperature distribution of slurry atomization drying was measured by new sandwich structure thermocouple with air pump. The results showed: The maximum SO2 removal and temperature decreasing...
This paper studied the wastewater treatment in GAO Yang Dyeing and Textile Industrial Park, with the dealing capacity of 19 × 104 ton/d, on its wastewater discharge, water reuse, energy saving and resources utilization. Through the process optimization consisted of the enhanced chemical conditioning, diagonal up-flow anaerobic reactor, intelligent closed-loop oxygen supply system, double membrane...
In this paper, model-based control is applied to an industrial plant, a flash dryer for starch, with the aim of improving the robustness of the regulation and to find a remedy to some undesired features of its behavior. Since on-line measures of the output variable of the process, the starch moisture, are not available, a classic regulation for the process is not possible and the desired moisture...
