PLC system configuration: 1, the original design uses two sets of Siemens S7-200 series PLC lime kiln furnace construction, based on actual experience of our company, now replaced by the use of a set of Siemens S7-300 series PLC control, so the original 2 sets of CPU S7-200 into the present station S7-300 CPU 1, the original Ethernet communication module 2 becomes now an S7-200 station S7-300 Ethernet communications module gas-burning kiln furnace, the remaining modules fairly priced kiln furnace equipment, thereby saving significant costs and reduce the company's costs. Programming software using STEP7 V5.4 (Authorized Genuine), monitoring software WINCC6.0 Chinese version (genuine licensed). Between PLC and PC using Ethernet communication mode, in the main control room set up industrial Ethernet switches, PLC system I / O margin greater than 20%. 2, HMI operating with two operating stations, PC Advantech IPC (dual hard drives, optical drives, UBS port, memory 2 × 512, CPU-P4 2.8) lime kiln furnace, 21-inch Philips tuck crystal displays, are used in the popular configuration. 3, for the actual situation of the scene, the scene is set for each kiln 2 meter box, mainly 8 kiln temperature and two gas temperature transmitter (DC4 ~ 20mA). 4, each I / O module DC24V power alone switch. 5, configure the analog input module with electrical isolation and fuse terminal blocks, to protect the module is not damaged. Lime kiln technical characteristics: (1) the combustion air is divided into primary and secondary air. Primary combustion air directly involved in the secondary air to the cooling air. Primary and secondary air are supplied by a single fan. The design of the secondary air temperature can rise up to 600 ℃, as combustion air, in order to save fuel provide favorable conditions. (2) the use of special combustion system to rotary kiln heating, in addition to using pulverized coal as fuel outside the low calorific value gas can also be used alone (eg, producer gas, calcium carbide exhaust, semi-coke gas) as fuel firing can also use a variety of fuels At the same time supply use. The calcination temperature can be adjusted by adjusting the air and gas flow. (3) measures to improve environmental protection. Calcination exhaust using pulse jet bag filter dust, to meet the national emission standards. In the vertical blanking point cooler it is also used baghouse dust. (4) high level of automation. Calcining system equipment manufacturing operations of regulation, control and alarm using PLC (programmable logic controller) in the main control room centralized control, and a screen display of the control points and the necessary interlock monitoring of the production process used in the operation parameters are automatically recorded and can be printed at any time.
