Abstract

The invention relates to an extraction kettle apparatus for separating coal tar, and concretely relates to an extraction kettle apparatus for separating coal tar through a mild extraction method. A strong magnetic stirrer is arranged in the center of a top cover, and a temperature measuring port, a pressure measuring port, a material inlet, an extractant inlet, a nitrogen inlet, a nitrogen outlet, a diffusing port, and valves connected with relevant tube ports are uniformly arranged in the circumference of the top cover respectively; an electric lift type lift tube lightweight component discharging system is arranged at the upper right side of the top cover; two hot steam heating coilers and corresponding hot steam inlets are arranged at the center outside a kettle; the material outlets of downward spreading valves are arranged at the outside surface portion of the kettle, and the downward spreading valves are respectively connected with a glass sight cup; three groups of sight glasses are arranged at the center outside the kettle; an interlayer heat insulation layer is arranged at the center outside the kettle; and a steam outlet, a material outlet and a valve are arranged at the bottom of the kettle. The apparatus has the advantages of simple operation, obvious energy saving and consumption reduction, high solvent recovery rate, easy automatic operation, low-carbon clean production, low investment cost, and less discharge of waste residues, the exhaust gas and wastewater.

Description

Technical field: [0001] The invention relates to an extraction kettle equipment for separating coal tar, in particular to an extraction kettle equipment for separating coal tar by a mild extraction method. technical background: [0002] High-temperature coal tar is a black or dark brown viscous liquid with pungent odor, which is a by-product of coking. The light components of coal tar are rich in a series of organic chemicals such as 1-4 ring aromatic compounds, phenols, nitrogen-containing, sulfur-containing and oxygen-containing heterocyclic compounds, which are used in the production of fuels, pesticides, medicines, dyes, It is an important raw material for coatings, synthetic rubber and various functional materials. It can separate nitrogen-containing heterocyclic compounds such as quinoline, isoquinoline and indole from light components. These high value-added polycyclic compounds are intermediates for the preparation of pharmaceuticals. An important raw material fo...
