Description

Exhaust gas treatment system and its treatment process in the production of dipped cord fabric

technical field

The invention belongs to the technical field of industrial waste treatment. In particular, it relates to a waste gas treatment system and a treatment process in the production of dipped cord fabrics. It specifically relates to a treatment system for waste gas produced in the production process of dipped cord fabrics and a process for using the system to treat waste gas.

Background technique

As the skeleton material of the tire, the dipped cord fabric is firmly combined with the rubber to withstand the internal and external forces of the rubber product to improve the strength of the rubber product, limit its deformation, and maintain dimensional stability. It is indispensable in the development of modern industry. The product.

In the production process of dipped cord fabric, the impregnation of the cord fabric is usually done by impregnating the white gray cloth obtained in the previous production with organic matter such as resin (the temperature is generally room temperature), and then drying (generally the temperature is about 130 ° C ~ 170 ° C ), drawing (generally at a temperature of 210°C to 245°C), setting (generally at a temperature of 210°C to 245°C), and cooling (generally at a temperature of 40°C to 70°C). Due to the presence of organic matter and high temperature treatment in this production process, waste gas containing volatile organic compounds (VOC) will be generated. Volatile organic compounds, according to the definition of the World Health Organization, are compounds with a boiling point of 50-250 °C, and a class of organic compounds that exist in the air in the form of vapor at room temperature. The hazards of volatile organic compounds are obvious. When the indoor VOC exceeds a certain concentration, people will feel headache, nausea, and limb fatigue in a short period of time. VOC will cause damage to the human liver, brain, and nervous system. Therefore, the VOC in the exhaust gas must be treated up to the standard before it can be discharged into the air, so as not to cause harm to the environment and human body.

In the dipped cord fabric production system, the top suction type is currently used for collection and treatment. In this process, the exhaust gas outlet cannot be completely sealed, otherwise the system parameters will be unstable due to the interference of the induced draft fan of the exhaust gas treatment system, which will seriously affect the dipping. The quality of cord fabric products. Therefore, when the waste gas treatment device is used for treatment, the treatment is not thorough, the waste gas is not completely collected, and the uncollected waste gas is directly discharged into the atmosphere, causing great harm to the environment. Moreover, a single system is used in the treatment process, and it is difficult to meet the standard when the exhaust gas concentration is high, and the final discharge into the air still causes great harm to the environment.
