Lime kiln is mainly composed of the kiln, the feeding device, discharging device, part of the device, feeding device, electrical, instrumentation, control devices, and other combustion devices consisting of dust. Different forms of lime kiln, its structure and calcined forms differ, the process is basically the same, but the value of the equipment is very different. Of course use of effects and certainly a difference. Calcined lime in China has a long history to the present, metallurgy, chemicals, building materials industries by increasing the amount of ash, lime its quality requirements are also increasing. However, there also exist for the production of quicklime there are a lot of low-cost ordinary shaft kiln. Plain shaft kiln production there are many disadvantages, such as low utilization factor of the kiln, it is less than 50%; high energy consumption per ton of coal ash amount in more than 160kg; the vast majority of ordinary furnace or semi-open upper opening Structure lime kiln equipment manufacturers, it is difficult to remove dust from lime kiln equipment Price, serious environmental pollution; feeding and ash directly operated almost entirely artificial, labor-intensive, serious damage to the health of operatives; inconsistent quality, health, burnt, nodulation generally above 30 percent, and can not be controlled. PLC system configuration: 1, the original design uses two sets of Siemens S7-200 series PLC, based on actual experience of our company, now replaced by the use of a set of Siemens S7-300 series PLC control, so that the original two S7- 200 CPU into the present station S7-300 CPU 1, the original Ethernet communication module 2 becomes now an S7-200 station S7-300 Ethernet communication module, the remaining modules fairly priced, thus You can save a lot of costs, 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, set the Industrial Ethernet switches kiln equipment in the main control room, 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), 21-inch Philips tuck new lime kiln crystal display device, are used currently popular configurations. 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.
