The system has overcurrent, overload and wrong operation safety protection device, when the equipment is abnormal, the system sends out sound and light alarm, and a chain of command, cut off the power supply of the electric equipment, to be abnormal after the termination of re starting operation. The system has multiple flue gas temperature and system pressure real-time monitoring function. Has a friendly user interface, easy to use, simple maintenance.

The temperature of rotary kiln and two combustion chamber are respectively provided with temperature detection element, is used to control the operation of the burner; the heat exchanger flue, water heat exchanger circulating water inlet and outlet air import and export, have set up a temperature measuring points of heat exchanger, used to control the running state and protect the equipment condition in design within the scope of. The temperature monitoring point is installed in front of the bag filter, and the analog signal is sent to the frequency converter. The speed of the alkali pump is adjusted by PI to control the alkali liquor quantity, and the temperature of the bag filter is kept constant.

On the one hand, through the continuous temperature automatic control, suppress the generation, to prevent re synthesis. Benzene organic compounds, it is chlorine plastic material produced in the combustion process. The decomposition of gas over 700e in flue gas at 400250e and a small amount of synthesis. According to this characteristic, in the design of this system, flue gas at about 1100e (two chamber) residence time is greater than 2S, the two dioxin decomposition; in order to reduce the temperature synthesis of two dioxin, two combustion chamber by the heat exchanger, the flue gas from 1100e quickly fell below 200e. On the other hand, the activated carbon adsorption section is placed in front of the bag filter, and the produced two dioxin is adsorbed on the activated carbon, and then removed by bag filter.
