Abstract

The invention belongs to the technical field of coal tar processing, and particularly relates to a coal tar desalting and dewatering device integrating ultrasonic demulsification and high-voltage electrostatic field coalescence. The device comprises an ultrasonic generator, an ultrasonic transducer, an ultrasonic acting section, an electric desorption tank, a transformer, an electrode plate, a water injection-drainage heat exchanger, a water injection pump and a circulating water injection pump, wherein the ultrasonic transducer is arranged in the ultrasonic acting section and is connected with the ultrasonic generator, the ultrasonic acting section is connected with the electric desorption tank through a guide pipe, the transformer is arranged at the top of the electric desorption tank, and the electrode plate is arranged in the electric desorption tank. Coal tar is demulsified in an ultrasonic-assisted strengthening mode, the demulsified coal tar enters an electric dehydration tank,and electric field strengthened dehydration is conducted under the high-voltage electric field strengthened coalescence effect.

Description

technical field [0001] The invention belongs to the technical field of coal tar processing, in particular to a coal tar desalination and dehydration device which adopts integrated ultrasonic demulsification and high-voltage electrostatic field coalescence. Background technique [0002] my country's energy structure is rich in coal, short of oil, and low in gas. Coal has always been the main energy source in my country. Coal tar is a liquid product obtained in the process of coal pyrolysis or gasification. Among them, low-temperature coal tar has the same application as petroleum Very similar, it can be used to produce liquid fuels (such as gasoline, diesel) through hydrogenation, and is also an important raw material for chemical production (naphthalene, phenol, etc.), which has important practical and strategic significance for its processing and utilization. Dehydration and desalination of coal tar is an essential pretreatment method to provide high-quality raw materials fo...
