Description
Technical field
The utility model relates to a kind of distil process system, a kind of specifically tar distillation process system of tar deep processing.
Background technology
China is big coal country, and coal tar is as the by product of coke production, and along with the development of iron and steel enterprise, the reasonable utilization of coal tar receives people's great attention gradually.The normal pressure one tower and two-tower type technology that each coke-oven plant's utilization of the whole nation at present is the most general, twin furnace double-tower type distil process is adopted in the NAPTHALENE FLAKES. (INDUSTRIAL GRADE distillation, and this process characteristic is that technical maturity is stable, and shortcoming is an atmospheric operation, with the vapour method distillation, the energy consumption height, wastewater flow rate is big.Also have and adopt the multi-tower type distil process, multi-tower type distil process characteristics are that the cut cutting is thinner, and normal decompression combines, but technical process is long.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of tar distillation process system of tar deep processing is provided.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: a kind of tar distillation process system of tar deep processing; Comprise tar stock groove, one section vaporizer of tar, tar flash evaporator and tarry cut tower; Be provided with tar interchanger I in the path between one section vaporizer of tar stock groove and tar, be provided with tar interchanger II in the path between one section vaporizer of tar and the tar flash evaporator, one section vaporizer top discharge of tar mouth is connected with the light oil medial launder; The top discharge mouth of tar flash evaporator is connected with the opening for feed of tarry cut tower; The middle part discharge port of tar flash evaporator is connected with the carbolineum medial launder, and the bottom discharge mouth of tar flash evaporator is connected with the carbon black oil Preparation tank, and the top discharge mouth of tarry cut tower is connected with the light oil medial launder; The middle part of tarry cut tower is provided with the mixed triolein discharge port, and the discharge port of tarry cut tower bottom is connected with the carbolineum medial launder.
Also be provided with the anhydrous tar medial launder in the path between one section vaporizer of said tar and the tar interchanger II.
The beneficial effect of the utility model is: the process system product of the utility model is many, and environmental pollution is little, and technical process is reasonable, and low power consuming and cost of investment are all lower.
