High-temperature heavy-oil-stain waste gas treatment system

Abstract

The invention provides a high-temperature heavy-oil-stain waste gas treatment system, and belongs to the technical field of waste gas treatment. The system comprises a high-temperature waste gas collecting device, a condensing device, a filtering device, an oil removing device, a molecule breaking device, an exhaust gas collecting device, an air inducing device and an exhaust pipeline; under the action of the air inducing device, high-temperature waste gas enters the high-temperature waste gas collecting device, is treated by the condensing device, the filtering device, the oil removing device, the molecule breaking device and the exhaust gas collecting device, and is discharged from a gas outlet of the exhaust pipeline. The high-temperature heavy oil waste gas treatment system provided by the invention can efficiently remove harmful gases such as stink and VOCs, has the advantages of no attenuation of treatment efficiency, small equipment wind resistance, low power consumption, low operation cost, low operation noise, simple and flexible operation, convenience and rapidness in maintenance, small occupied area and easiness in installation, is simple and easy to operate in a control method, and has the popularization and application values in the technical field of waste gas treatment.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a high-temperature heavy oil pollution waste gas treatment system. Background technique [0002] Copper tube oil and fin oil are required in the production process of air-conditioning condensers and exchangers. The oil stains remaining on the copper tubes and fins affect the heat and cold exchange. Oil stains on the sheet are completely evaporated. The whole drying process can be divided into: heating section (room temperature ~ 150 ° C), constant temperature section (150 ~ 180 ° C), cooling section (150 ° C ~ room temperature). Drying is the core process of the two-device component workshop. During the drying process of finned tubes and copper tubes, a large amount of oil mist and organic waste gas (VOCs) are generated. The exhaust gas contains components of fin oil and copper tube oil. Alkanes, the number of carbon atoms is 7-18. These oil mist and organic waste ...

Problems solved by technology

However, this method has strong selectivity for organic pollutants, limited purification capacity, and requires regular replacement of the catalyst. The use and maintenance costs are relatively high, and the free radicals generated during the photocatalytic process are easily combined with oxygen in the air to form strong oxidizing properties. ozone, resulting in secondary pollution
