It increases the workload and labor intensity of operators. 3. It is easy to cause damage to storage tank equipment. 4. It increases the difficulty of solid waste treatment. 5. It increases the production cost. 6. There are personnel safety risks in regular switching and cleaning. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the present utility model provides a device for preventing the precipitation and aggregation of asphaltene in esterification acid water, which solves the following problems existing in the existing device: 1. It affects the stable operation of the esterification system. 2. It increases the workload and labor intensity of operators. 3. It is easy to cause damage to storage tank equipment. 4. It increases the difficulty of solid waste treatment. 5. It increases the production cost. 6. There are personnel safety risks in regular switching and cleaning.
[0005] To achieve the above object, the present utility model is realized through the following technical solutions: A device for preventing the precipitation and aggregation of asphaltene in esterification acid water, including a first esterification kettle, the first esterification kettle is connected with a second esterification kettle, the lower end of the second esterification kettle is connected with a first filter and a second filter, the first filter is connected with the input end of a material circulation pump, the output end of the material circulation pump is connected to the inside of the second esterification kettle, the second filter is connected with the input end of a material delivery pump, and the output end of the material delivery pump is connected to a waste acid device incinerator.
[0006] Preferably, both the first esterification kettle and the second esterification kettle can carry out esterification gas phase.
[0007] Preferably, both the material circulation pump and the material delivery pump are large flow pumps.
[0008] Beneficial Effects
[0009] The utility model provides a device for preventing the precipitation and aggregation of asphaltene in esterification acid water. The utility model designs a structure for promoting the complete dissolution of asphaltene in acid water. The first esterification kettle and the second esterification kettle can carry out esterification gas phase. During the esterification operation process, in the second esterification kettle, a large-flow material circulation pump is added to force the acid water in the second esterification kettle to circulate in a large flow, so that all the asphaltene in the acid water is dissolved in the acid water and will not be sucked out, aggregated and condensed. Through the forced circulation of the large-flow pump, all the asphaltene in the acid water is dissolved in the acid water, and will not be sucked out, aggregated and condensed. There is no need to switch and clean, no need to treat solid waste, and the stable operation of the device can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS
