Rotary kiln achieves calcining by high temperature. If there is no proper operation, malfunction may be caused. Professional engineers from Zhengzhou Taida Group give you specific answers for anti-explosion measures.
1. Establish anti-explosion system in the running process of rotary kiln
Alarm system for Air pressure, temperature, flow quantity and pressure of coal gas
a. Light signal, automatic coal feeder, ash-discharge system, pressure-adding system, blower and sound and light alarm device;
b. Pneumatic detection Checking system for avoiding coal gas explosion;
Install anti-explosion film for main air pipe, dust removal system and relevant system; water seal should be installed for coal gas system for preventing coal gas going back.
c. Correct operation in the running process for
rotary kiln. Here are some specific information.
d. Before starting up, finish debugging work for alarm system first. Adjust the pressure of alarm system and confirm if the valve switch is right. Finally, carry out comprehensive test for general interlock;
Do nitrogen content analysis before coal gas interconnection. The nitrogen content should be less than 1%;
In the production process, pay attention to change of coal gas, temperature and pressure. If there is something not consistent with standard index, deal with it in time.
2. The inspection of rotary kiln is a very important work.
a. Cut the source of coal gas before inspection and maintenance; clean the coal gas, hand-hole and bleeder pipe;
b. Get some air sample for co analysis in order to guarantee there is no explosive air formed in the ignition process; if the fire stops, stop the coal gas first; after eligible analysis of inner furnace, ignite again.
After these detailed explanation, I believe that you have learned a lot of rotary kiln knowledge. Hope you can use these methods in the running process of
rotary kiln.
