How to do the safe production of washing powder

Sodium alkyl benzene sulfonate is a raw material in the organic chemical industry chain of application, hydrogen, benzene, hydrochloric acid, sodium hydroxide, etc., after organic synthesis, and then under certain preconditions, it is mixed with sodium tripolyphosphate, sodium sulfate It is a metal cutting fluid prepared by high-rise spray dryer production and processing. The raw materials used in the production process of washing powder, the resulting side and upper body, and the semi-finished product processing. Manufactured products and their organic waste gas, waste. Part of the sewage from Guangzhou Sun Yat-Sen University is flammable. Flammable, explosive, and easily poisoned. Dangerous goods with strong decay, such as benzene, hydrochloric acid, sodium hydroxide, alkyl benzene, hydrogen, aluminum trichloride, mud feet, hydrogen chloride, etc., must be carried out in accordance with the characteristics of the production of fire, safety and explosion-proof type. Commercial Insurance Methods. (1) Fire hazard characteristics of washing powder production The fire accident risk of generating washing powder is likely to be analyzed from four aspects. A. From the characteristics of raw materials, raw materials. Most of the side products and finished products have the risk factors of incineration, occurrence or both poisoning and strong decay, and the fire hazard characteristics of key raw materials. When the management system of machinery and equipment is defective and there is leakage, the flammable gas and gas in this chemical substance will produce a mixture. When encountering high fever, impact or friction in production, mechanical equipment sparks and electrostatic induction flames , The fire used for heating or testing, that is, incineration treatment or occurrence, if the leakage of harmful gas, it can also poison the actual operating staff. B. From the point of view of the preconditions for the reaction and actual operation, some reflect the exothermic reaction itself, such as hydrogen, condensation reaction, sulfonation, and neutralization. Some work at high temperature, such as de-benzene, de-oiling, mud foot solution, powder spray forming. Some work under working pressure, and some work under high temperature and working pressure, if the instrument panel fails during the production process. Poor temperature control and pressure control, incorrect feeding of materials, or interruption of refrigeration and mixing due to water and power interruptions are likely to cause organisms to ignite and punch materials to catch fire. The impact toughness causes cracks, and the high-temperature raw materials break through and catch fire when they meet the gas. In addition, the high temperature beyond the self-ignition point can cause the raw materials to be carbonized and slag in the equipment management system, which will not only block the channel and cause explosion, but also continue to open the gate valve when the material is fed. Or gas fire occurs when the barrel is blocked and decoked, reflecting and actual operation prerequisites. C. From the point of view of the open fire, in addition to the test of hot work with a switching power supply box, there are many heating sources in production. Generally, the heating method of steam and inductor is used. The layer is not good, the moisture returns and electricity runs, causing short circuit faults between turns, and it will also cause leakage of flammable materials to catch fire, such as heating of the deoiling tower inductor. D. From the perspective of production site, the process flow of isopropyl titanate, condensation reaction, deoiling, debenzene, and mud foot solution in alkylbenzene production. Sulfonation in the production of washing powder, middle heel, preparatory treatment, air conveying, tower bottom, oil-furnace process flow and its vaporization raw material operation area and other production parts are likely to cause fire hazards. The key is to take precautions, because this part is not only flammable. Explosive substances, as well as pyrogens, switching power supply, only the fusion of internal and external pyrogens, and their mutual effects, will cause incineration or occur, and endanger all production. Therefore, this part is not only an important part of production, but also the key to protection. (2) Fire, safety and explosion-proof method of washing powder production The washing powder production is composed of the main production workshop, the production workshop and the forming production workshop. According to the fire hazard level, isopropyl titanate, condensation reaction, deoiling. Debenzene. solve. Sulfonation, middle heel and other technological processes, oil house. ;The liquid raw material warehouse is a Class A fire accident risk, and other production parts are Class C. ; Class A production area should be strictly prohibited to smoke, Class C is a production area, and all production areas are strictly prohibited from smoking, and their fire safety measures are the key to the construction at that time. . mechanical equipment. Practical operation and remediation level.
