Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a continuous reaction kettle for petrochemical additives. Background Art

[0002] Petroleum additives refer to a small amount of substances added to the petroleum processing and petroleum products that have physical or chemical effects. They are also called petroleum additives. The equipment used in the processing of petroleum additives is usually a reactor and a kneader. The broad understanding of a reactor is a container for physical or chemical reactions. The structural design and parameter configuration of the container are used to achieve the heating, evaporation, cooling and low-speed mixing functions required by the process. The chemical additives added in the petroleum processing process may produce toxic and harmful exhaust gases during chemical reactions in the reactor, which endangers the personal safety of operators when inhaled. In addition, the existing reactor directly adds chemical additives, and solid waste is generated after the internal chemical reaction. After accumulation, the reaction effect is affected, and the reactor cannot achieve quantitative discharge when discharging materials. Therefore, a continuous reactor for petrochemical additives is needed.

[0003] The existing patent document with the technical disclosure number CN202221777151.4 provides a petroleum additive reactor, including a reactor body, a movable structure is fixedly connected to the lower part of the outer surface of the reactor body, an additive groove is opened at the upper end of the reactor body, a motor is fixedly connected to the middle part of the lower end of the reactor body, the output end of the motor passes through the lower end of the reactor body and is fixedly connected to a stirring structure, a cover plate is hinged at the rear part of the upper end of the reactor body, and a device pipe is fixedly connected to the upper part of the outer surface of the reactor body. The petroleum additive reactor described in the utility model is convenient for moving the reactor to a use position by arranging a moving structure and a stirring structure, thereby improving the stability of the reactor during use, avoiding the reactor from tipping over, facilitating the use of the reactor, increasing the stirring area of ​​the petroleum additive, reducing the stirring resistance of the petroleum when stirring the petroleum additive, increasing the stirring efficiency of the petroleum additive, and improving the stirring efficiency of the petroleum additive. However, when the CN202221777151.4 technology is in operation, it is impossible to collect and process the waste gas generated by the chemical reaction, it is impossible to filter it, and it is impossible to perform quantitative discharging. Therefore, a continuous reactor for petrochemical additives is urgently needed. Utility Model Content
