The annual output of workshops EL30/90, B294 and D50 of Lanhua silicone Co., Ltd. is 0.5 million tons of butanone oxime/kloc-0 and 3,250 tons of organosilane, which will produce volatile organic compounds VOCs and ammonia gas, which may be the cause of deflagration. Volatile organic compounds, including non-methane alkanes (alkanes, alkenes, alkynes, aromatic hydrocarbons, etc. ).) and oxygen-containing organic compounds (aldehydes, ketones, alcohols, ethers, etc. ).), reaching a certain concentration in the air, will explode in case of open flame. Generally speaking, electrical equipment used in explosive gas environment (or dust environment) should be explosion-proof.
The explosion-proof electric oil stove designed and used by Ouneng Machinery for chemical plants is mainly considered from three necessary conditions. By limiting the contact between electric sparks and combustible objects, the explosion is limited.
Chemical plants consume a lot of heat, and the commonly used boiler is heat conduction oil furnace. If the heat transfer oil leaks in the heat transfer oil heating system, it will do great harm to the system. The leaked high-temperature heat transfer oil will undergo oxidation reaction when it comes into contact with air, releasing heat. The greater the contact area with air, the faster the fire and explosion will occur. If the sprayed heat transfer oil is atomized particles, the contact area with oxygen will be larger, and a fire or explosion will occur instantly.
