Discussion on the exhaust ring coil of the acrylonitrile reaction gas cooler
Thread Content
Teacher, may I ask what the normal pressure is for the exhaust ring pipe of the reaction gas cooler? Is the vapor flowing through the normal ring pipe pure vapor or a mixture of vapor and liquid? Also, may I ask the teacher, what factors can affect the exhaust pressure and flow rate of the exhaust ring pipe?
In the heat transfer process, the exhaust ring coil of the acrylonitrile reaction gas cooler is an important component used to safely discharge the smoke from the cooler, thereby preventing reaction gases or escaped smoke from causing a fire. The design of the exhaust ring tube should possess excellent corrosion resistance, the ability to reduce moisture and damping effects, durability, safety and reliability, as well as effective exhaust performance. It also requires a installation without dead corners, with the piping structure kept as simple as possible. At the same time, to prevent vaporization, deposition, and increases in internal temperature, exhaust pipes must be made of high-quality thermal insulation materials, and advanced thermal insulation techniques must be employed to ensure their insulating properties. Furthermore, the exhaust pipes should have a proper sealing structure during equipment operation, in order to limit the emission of NC, hydrocarbons, and other harmful gases, thereby reducing environmental pollution.
Teacher, I saw in your reply that there was a mention of preventing vaporization – is water being used for exhaust in this system? On my end, the shell side of the heat exchanger uses boiler water
