How to safely produce laundry beads

Sodium alkylbenzene sulfonate is a laundry gel bead that uses petroleum, chlorine, benzene, sulfuric acid (chemical formula: H2SO4), caustic soda and other chemical industrial raw materials. After chemical synthesis of monomers, the monomers are combined with tripolyphosphoric acid under certain conditions. A synthetic washing agent made of sodium, sodium sulfate and other additives through high-tower spray drying processing.
The raw materials, intermediates and semi-finished products used in the production process of laundry gel beads. Finished products and waste gas, waste residue. Most of the wastewater is flammable. Explosive and easy to be poisoned. Strong Corruption
Dangerous goods, such as petroleum, benzene, sulfur (chemical symbol: S), acid, caustic soda, alkylbenzene, chlorine, aluminum trichloride, mud feet, hydrogen chloride, etc., must be fireproof according to the characteristics of the fire face produced Mainly explosion-proof, and take safety measures.
(1) Fire risk characteristics of laundry gel beads production
The fire hazard of synthetic laundry beads can be analyzed from four aspects.
A. From the nature of raw materials, raw materials. Intermediate products and finished products are mostly dangerous items that burn, explode or are both poisoned and highly corrosive, and the main raw materials have fire risk characteristics.
When the equipment system is not tight and there is leakage, the combustible gas and air in these substances form an explosive mixture. Whenever it encounters mechanical sparks and static electricity generated by high heat, impact or friction in production (a kind of static State of charge) sparks, heating or open flames for maintenance, that is, burning or exploding, if toxic gas leaks, it can also poison the operator.
B. From the perspective of reaction and operating conditions, some reactions themselves exothermic, such as chlorine, condensation, sulfonation, and neutralization. Some work under high temperature, such as debenzene, deoiling, mud foot treatment, powder spraying and molding. Some work under pressure, some work under high temperature and pressure, if the instrument fails during the production process (guò chéng). Improper temperature control and pressure control, incorrect feeding, or interruption of cooling and stirring due to water or power failure, may cause organisms to explode and burst into flames. At the same time, high temperature can also cause tensile extension of the equipment system, affecting its mechanical strength and causing cracks. The material will ignite spontaneously when it comes out of the air.
In addition, the high temperature exceeding the self-ignition point can cause carbonization and coking of the material in the equipment system, which will not only block the passage and burst, but also open the valve when the material is discharged. The main components of laundry gel beads are anionic surfactants, sodium alkylbenzene sulfonate, a small amount of non-ionic surfactants, plus some additives, phosphates, silicates, sodium sulfate, fluorescent agents, enzymes, etc. It is made by mixing, powder spraying and other processes, and now most of them use 4A fluorspar instead of phosphate. Laundry gel beads refer to powdery (granular) synthetic detergents. Or encounter air spontaneous combustion, reaction and operating conditions during barrel blocking and decoking.
C. From the point of view of the ignition source, in addition to the power box overhauling the fire, there are many heating sources in production. Steam and induction heating are usually used. Inductive heating is sometimes due to poor sealing, poor insulation, and damp. : The object is infiltrated by moisture) running out of electricity will cause a short circuit between turns, which will also cause the leaked combustibles to catch fire, such as the induction heating of the deoiling tower. The synthetic detergent for laundry gel bead processing is based on surfactants as the main component, and is equipped with a suitable amount of builders with different functions. Laundry gel beads refer to powdery (granular) synthetic detergents.
D. From the perspective of the Producer site, the chlorination, condensation, deoiling, debenzene, and mud foot treatment processes in the production of alkylbenzene. In the production of laundry beads, sulfonation, neutralization, pretreatment, air conveying, tower bottom, oil room process and liquefied raw material storage area are the most prone to fire and explosion accidents. The above production parts belong to Class A fire insurance and must be focused Take precautions (pointing to the solution to the problem), because these parts are both combustible. Explosive media, heat sources, and power sources, as long as the internal and external fire hazards combine and interact, they will burn or explode, affecting the entire production, so these parts are not only the key to production, but also the focus of defense.
(2) Fire-proof and explosion-proof measures for the production of laundry beads
The production of laundry beads is composed of a synthesis workshop and a molding workshop in the main workshop. According to the degree of fire hazard, chlorination, condensation and degreasing are performed. The synthetic detergent for laundry gel bead processing is based on surfactants as the main component, and is equipped with a suitable amount of builders with different functions. Laundry gel beads refer to powdery (granular) synthetic detergents. Debenzene. deal with. Processes such as sulfonation, neutralization, and oiling. ; The liquid raw material warehouse belongs to the Class A fire hazard, and other production parts belong to the Class C. The Class A production area should be no fire, and the Class C is the production area. All production areas are prohibited from fireworks. Their fire prevention measures are mainly reflected in the buildings. equipment. Operational control and management.
