The 180,000 ton/year ABS plant Technology upgrade project was successfully completed, which realized the leap from continuous operation to full load operation. Modification of ABS equipment by million

' Technical innovation after driving the first month to increase production of ABS products 18,100 tons, to create benefits million yuan.

"A recent 180,000 tons/year of the Jilin Petrochemical Plant Technology upgrade and transformation of the operation of the report, such a message. It is understood that the device has been running for 20 years, some equipment into the aging state, fault frequency, cutting granulator, the problem of too many rotary valve has emerged.

They take advantage of this year's overhaul of the time, the device to implement technical transformation, to break the bottleneck problem, improve the stability of the device. The San pelletizing machine update is the most serious of the renovation project.

But there was a spate of accidents. ' We are in the temporary line after the power-up commissioning, the cutting machine touch screen and PLC CPU communication is not smooth, touch screen display garbled. After investigation, it is found that the baud rate setting in the control system is not in accordance with the cable length. After the elimination of this failure, the cutter screen full screen is the alarm information, flashing constantly. ' The person at the scene was very worried, ' said Sun Desheng, a competent instrumentation technician. They picked up the drawings on the fault information again from scratch, and finally found that the design unit drawings and manufacturers to provide the drawings are not uniform, resulting in construction unit wiring errors.

The crux of the problem has been found, a troubleshooting solution is not difficult, and eventually will be all the problem of cutting machine meter all solved. Instrument problem solved, when the commissioning, the accident occurred again: San unit cut-grain water overflow. Dr. Lu Shulai, chief engineer of the plant, said the initial conclusion is that the dryer plugging material.

After checking the inlet channel of the dryer, checking the outlet of the dryer material and the normal of the steering and air duct, they focused their attention on the equipment itself and finally found the clue. Because it is an upgrade project, vibrating screen and other equipment is the use of the original equipment, drying box belongs to the new installation equipment. In order to connect two devices in a straight line, the installation of man-made changes in the angle of the dryer discharge line, the angle is small, the resistance is large, resulting in the drying box discharge capacity of the discharge line is reduced, prone to plugging material. He said, the illness found, the technician at the fastest speed to the dryer discharge pipeline transformation, and successfully completed the installation of the pipeline, the San particles into the vibrating screen briskly, was transported to the silo.
