Stenter machine running emissions of waste gas not only contains a lot of soot, but also polyphenyl organic matter, printing and dyeing auxilia, oil and other components, each stenter machine generally emissions of particulate matter 150 -- 250mg/m3, 40 -- 80mg/m3 lampblack.The emission of oil, smoke and dust has great harm to human health and the environment.
The Stenter machine is the key equipment for finishing textile printing and dyeing.In the process of cloth heat setting, the temperature is high, so a large number of high temperature gas is produced in the stenter machine oven, high temperature gas contains organic oil, dyes, dye additives, lubricating oil, fiber particles and other pollutants.
Now commonly used stenter machine exhaust gas treatment usually have water spray process and electrostatic process.
The principle is as follows: Strong electric field is used to electrify dust particles. When particles with positive/negative charges pass through the dust removal electrode, they will be adsorbed by negative/positive electrode plates respectively, thus achieving the purpose of dust removal.
Water spray process
The principle is as follows:
The high temperature exhaust gas generated by the stenter machine enters the exhaust gas purifier, after the diversion area through slow flow, diffusion into the spray area, smoke in the spray area and high pressure water fog turbulence contact, the harmful gas include the exhaust gas, fiber, dust, oil fog is captured by the water mist after the bottom of the purifier drain into the oil and water separation tank.The air purified and cooled by spraying enters the dewatering area from the spraying area. The dehydrated clean air is discharged into the atmosphere through the exhaust pipe at the top of the purifier.
