Intelligent control system for ultrahigh-calorific-value garbage drying process

Abstract

The invention provides an intelligent control system for an ultrahigh-calorific-value garbage drying process. The intelligent control system comprises an intelligent control center, a temperature sensor group, a controller, a flow valve, a drying furnace, network communication equipment and an upper computer monitoring station. According to the system, the temperature sensor group is installed inthe drying furnace and connected with the drying furnace, temperature distribution of the drying furnace is sensed in real time, data are transmitted to the intelligent control center, the intelligentcontrol center receives the data, a fuzzy algorithm and a BP neural network algorithm are adopted for calculation, whether the data transmitted by the temperature sensor group in real time reach a preset value or not is judged, an intelligent control instruction is sent out accordingly, the intelligent control instruction is sent to the controller, the controller is connected with the intelligentcontrol center and the flow valve, the opening and closing degrees of the flow valve are adjusted through the controller to control the flow of heating gas, it is ensured that temperature distribution values of all points measured by the temperature sensor group in the drying furnace are within a range of a set control value + / -10 DEG C, and the control level of the system is higher than the current conventional PID control level.

Description

technical field [0001] The invention relates to the technical field of automatic control of garbage drying systems, in particular to an intelligent control system for a garbage drying process with ultra-high calorific value. Background technique [0002] In view of the characteristics of high moisture content and relatively low calorific value of urban waste in my country, in the pre-treatment subsystem of domestic waste pyrolysis and gasification, the ultra-high pressure dry and wet sorting and pressing technology is used to separate the quality of domestic waste into dry waste at one time. components and wet components. The dry components are mainly composed of plastic, paper, wood and bamboo, fabric, rubber and ash. The ultra-high calorific value waste passes through the pyrolysis gasification device to generate combustible gas, and after passing through the purification system, it enters the internal combustion engine to generate electricity, so as to maximize the value ...

Problems solved by technology

[0005] At present, the conventional PID control is commonly used in the drying process control. The drying process is not highly intelligent and has poor self-adaptability. Moreover, the drying effect is unstable or the heating is often caused by too much or too little heating gas supplied. Therefore, it is urgent to develop an intelligent control system for the ultra-high calorific value garbage drying process to realize the intelligent, safe, fast and stable operation of the ultra-high calorific value garbage drying system.
