RTO Regenerative Thermal Oxidation and Heat Recovery Equipment has been used widely in coating, printing, plastic and rubber, and electronic industries, for thermal oxidation and heat recovery of waste gas emitted from the coaters, with the advantages of energy saving, efficiency improvement, emission reduction and environmental protection. After the treatment by the RTO equipment, the emission index of organic waste gas can fully satisfy the National Standard GB 16297－1996 "The Standard of Atmospheric Pollutants Emission", which reduces atmospheric pollution greatly, to protect both the environment and the people's health.
The RTO equipment heats the VOC waste gas (Organic solvents in the waste gas are including acetone, butanone, ethyl acetate, methanol, cyclohexanone, xylene, etc. These solvents have a higher value of combustion heat.) to about 800℃, to make the hydrocarbons in the waste gas generating oxidation reaction at the high temperature, to become CO2 (carbon dioxide) and H2O (water), and then to be emitted to atmosphere. The thermal efficiency is more than 95％, and the elimination rate of VOC (Volatile Organic Compound) is more than 97%. The RTO equipment achieves the periodical circulation and recovery of heat energy from the VOC oxidation. The recovered heat can be used for heating of the ovens on the coaters by a heat medium such as heat-conducting oil or steam. The waste heat recovered by the RTO equipment can satisfy the heat demands of the ovens.
Except for auxiliary preheating by fuel oil while startup, when the emission and concentration of VOC reach a certain index, the RTO equipment does not need any auxiliary fuel during normal operation, which can save energy and protect environment.
The machine uses PP or PE as raw material, through the flow-casting coating and lamination technology, achieving single-sided / double-sided coating or paper-plastic lamination with substrates (plastic woven fabric), to produce coated or laminated products. The machine is equipped with advanced electrical and mechanical devices throughout the whole production flow from substrate unwinding, lamination to winding, to achieve single control and group control. The dual-station unwinder uses EPC for automatic guiding control of substrates, and brakes for surface tension control of substrates, achieving pneumatic splicing and non-stop roll changing. The laminator is equipped with a preheating roll for preheating and drying of substrates. Laminating roll, silicon rubber roll and press roll are of dual-interlayer forced water cooling structure, with good cooling effect. The dual-station winder adopts constant-tension surface friction winding, pneumatic transverse cutting, roll changing without shutdown, and equipped with an adjustable edge-trimming device, an edge-strip blowing device, and a length counting device.
