The Fire Risk of Cigarette Factory and Research on Design Technology of Fire Protection System

Cigarette and tobacco production plant is an important place for storage, you need to set up safe and reliable fire protection systems in order to cope with all kinds of unexpected fires. This paper focuses on the joint Kobo cigarette factory, power plant, experimental studio, deployment center, library and finished products such as flavors and fragrances manufacturing and warehouse storage areas and causes a fire hazard, and the actual operation of the system through the fire management process for each system problems encountered, suggestions cigarette factory fire system design. KEYWORD: Tobacco; Fire risk; Complex production workshop; Stores; Fire equipment International Conference on Industrial Technology and Management Science (ITMS 2015) © 2015. The authors Published by Atlantis Press 1818 building fire safety design recommendations apply to the operation of the fire protection system in accordance with the current problem. 2 CIGARETTE FACTORY FIRE HAZARD ANALYSIS 2.1 Tobacco is a Class C flammable solid. According to “architectural design code for fire protection” (hereinafter referred to as “Building Regulations”), and “high-rise building fire protection design” [2] [3] [4] (hereinafter referred to as “high regulation”) requirements, Tobacco store fire hazard characterization for the Class C in “combustible solids”, lighted tobacco is 220°C, the main manifestations of the phenomenon of spontaneous combustion burning, smoldering, fire these three forms. There can lead to smoldering flame burning, it's burning into the source of fire burning and spontaneous combustion (no ignition sources). Principle of spontaneous combustion spontaneous combustion of tobacco and other substances, like: Tobacco itself is self-heating, heat is generated when the temperature is greater than the heat loss to the ignition point, and then occur naturally. 2.2 Other reasons can lead to burning tobacco. Paper production and operation of tobacco used, tow, cigarette trademarks, cigarette waterproof wrapping paper, cardboard boxes, linen sheet and other accessories fire hazard, cardboard boxes, etc. are flammable, combustible, thermal decomposition temperature, spontaneous combustion points are relatively low. Ignition is generally carton 130 °C, combustible solid heat can break down, and its thermal decomposition temperature (ie, the initial temperature of the heat decomposition occurs), ignition point (when heated to a certain extent can automatically burn the lowest temperature) is a fire risk assessment one of the main parameters. The lower the thermal decomposition temperature, the lower the ignition, combustion faster, the greater the risk of fire; the lower the ignition point, the greater the tendency to burn, the greater the risk of fire. 2.3 Produced a kind of electrical fire hazards Tobacco Factory production of a large amount of electrical equipment, electrical equipment when the work overload will cause short circuit, arc, spark, spark ignited the existence of tobacco, accessories carton cardboard, ceiling grid and fiber optic cable twisted pair cable, such as a fire hazard sex is one of the most important fire hazard. According to statistics, the fire occurred due to an electrical fire caused more than 80%. 2.4 Fire hazard may occur when tobacco fumigation and spraying to kill pests Cigarette factory every year to pests silk, cigarette packages and experimental line production line process of fumigation and spraying treatment. The use of aluminum phosphide fumigation and spraying, when aluminum phosphide case of acid or water and moisture, and can react violently, spontaneous combustion can emit toxic phosphine gas. Phosphine can effectively inhibit and kill microorganisms, to prevent tobacco mildew. But it is flammable, toxic, odor with acetylene. When the air reaches a certain concentration of phosphine, will spontaneous combustion and detonation; when the temperature exceeds 60°C, immediately spontaneous combustion in air can react with oxidants, cause a fire or explosion, fire more dangerous. 2.5 When a potentially explosive gas leak fire hazards Current cigarette factory boiler room, expanded tobacco puffing end, HTD hot end, kitchen and other places have to use a unified municipal gas supply, and as production increases, the amount of naturally increased. Received from the municipal supply pipe factory skid station, factory or building by an underground natural gas pipeline grid interspersed each use to end. Pipeline leak and use client has the possibility of an explosion caused a fire hazard prone. 2.6 Ming fire ignition sources external fire hazards Most new cigarette factory covers an area of technological transformation in recent years, a large, construction of the plant species to reach hundreds of thousands of square meters, the new plant due to the design and technical innovation of the actual use of the process there are some places will not need a third-party service, please units of buildings and production equipment to improve maintenance, repair process requires a temporary hot work, each year after the author's temporary hot work permit approval of thousands of copies, and leave the rest of the job, such as protective measures and monitoring done enough good, it is easy to cause a fire hazard. On the other hand, foreign workers out of the workshop, finished area who are many and complex, there are a small number of personnel to carry fire approach, there is a fire hazard.
