In recent years, one of the research hotspots of activated carbon is to use cheap agricultural and forestry wastes as raw materials and simple and clean process to prepare biomass activated carbon with high economic benefit and good adsorption performance.
If the agricultural and forestry wastes are effectively utilized and turned into treasures, it can not only create certain economic benefits, but also reduce its pollution to the environment, and achieve the purpose of treating waste with waste.
In this paper, using biomass (corn cob, rice husk and peanut shell) as raw material, the experimental research on the preparation of activated carbon from biomass was carried out on the self-built experimental platform, and the activation temperature, activation time, impregnation ratio and impregnation time and other activation and physicochemical characteristics were systematically studied.The surface area of the activated carbon should include the inner surface area and the outer surface area. In fact, the adsorption properties mainly come to the inner surface area of the white Li large, so it can not be mistaken for: the activated carbon grinding and grinding will significantly improve the surface area to improve the adsorption force.
Many adsorbations are recursive physical adsorption, The carbonization process of carbonization furnace is a complex chemical reaction process, which has the characteristics of multivariable coupling, nonlinear, time delay and so on.
It is difficult to establish accurate mathematical model for furnace outlet temperature and furnace tail pressure, and it is difficult to realize it by means of general control process.www.wyactivatedcarbon.com
Through the comparison and analysis of the fuzzy PID control and the parameter self-adjusting fuzzy PID control simulation, the final determination of the parameter self-adjusting fuzzy PID control algorithm, the blower and induced draft fan speed adjustment, the simulation shows that the control effect is good, has a certain application value.bulk powdered activated charcoal
The touch screen is used to realize the human-computer interaction function, and the monitoring system is established to monitor the process parameters such as temperature and pressure in real time. The functions of setting formula, alarm and curve recording are set up to meet the monitoring situation of the production site.that is, the adsorbed matter is a fluid, which is adsorbed by activated carbon at a certain temperature and pressure. At high temperature and low pressure, the adsorbed matter desorbs out, and the inner surface of activated carbon returns to its original state.
