Cigarette Processing Line Fire Fighting System
1. Application scope
The infrared thermal imaging early fire detection & alarming system protect and inspect all objects which internal abnormal heating & temperature rising. The whole heating and temperature rising procedure to be inspected and shows on the screen and alarming. The infrared thermal imaging early fire detection & alarming system for tobacco industry and other storage industries which the stack of internal heating monitoring is the other fire alarm system can not be replaced.
Infrared thermal imaging early fire detector adopt the second generation of non refrigeration focal plane sensor . It combine the image signal processing and embedded industrial control technology to anticipate the internal temperature based on the measured surface temperature of the target object.
According to the surface temperature rise rate, the actual value of the surface temperature and the internal temperature anticipation value, comprehensive judge whether it is on fire trend. And send out abnormal or alarm signal.
2. Characteristic
Infrared thermal imaging detector has characteristics such as small size, easy installation, accurate temperature measurement, high integrated level, effective long distance, no affection by the field visibility, all-weather use characteristics.
Especially with respect to the other fire sensors & detectors through the temperature, smoke, flame, etc. The infrared thermal imaging detection system can give an alarm signal, effectively avoid fire when the inspecting object internal heat aggregation and before smoldering, smoke, flame.
And this system can output standard video image with the special industrial control computer. It can carry out many functions such as alarm, remote alarm, video transmission, image playback. It is especially suitable for petroleum, chemical industry, papermaking, large warehouses, grain depot, unattended station, tobacco industry, open type & large space, etc where the conventional detector can not be used. It is a new generation of integrated and efficient fire detecting and early warning and alarm equipment.
3. Multi zone alarm
In the remote control room we can through the software set the infrared thermal imaging detector, each infrared detector can be set for a plurality of alarm area, each area can be individually set reminders temperature, pre-alarm temperature, alarm temperature and remind temperature rise, pre-alarm temperature rise, temperature rise alarm.
Tobacco industry include the many procedure such as leaf tobacco purchasing, packaging, transportation, storage and green leaf redrying processing and cigarette storing and selling etc.
Tobacco, cigarette,, hemp rope, cardboard boxes are easy flammable and combustible materials. In the event of a fire, in a very short time will cause disastrous consequences, brings huge property losses to the enterprise
1. Fire physical characteristics of tobacco leaves
Tobacco flame combustion, and smoldering. The smoldering is imminent signal of the flame.
The combustion of tobacco leaves is divided into fire source combustion and self-ignition.
A. The fire source combustion: when the heating temperature of tobacco to reach its self ignition point (about 175ºC), it can happen combustion.
B. Self-ignition: tobacco self-ignition is a biochemical reaction, oxidation and decomposition reaction of the comprehensive effect of the results. The first is parasitic microorganisms and enzymes and biochemical reaction exothermic, with the accumulation of heat and temperature, when the temperature rises to 70ºC-80 ºC, microbial death and biochemical reaction is terminated, generated unstable products in the process will further oxidation reaction exothermic heats up, when tobacco temperature reach the self-ignition level and then tobacco combustion.
C. The carton, hemp rope, cardboard and other packing accessories which used in tobacco industry and they are very easy on fire. Their self -ignition point is low. Normal the carton burning point is over 130ºC, hemp material self-ignition point is 150ºC-200ºC. The ignition temperature is lower, the burning speed will be faster, the fire risk will be huge. Self-ignition point is low, combustion tendency will be larger, fire risk is huge.
