Description

Technical Field

[0001] The utility model relates to the field related to coal tar, in particular to a distillation device for coal tar production. Background Art

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor generated during the dry distillation of coal. Coal tar can be divided into low-temperature coal tar, medium-temperature coal tar and high-temperature coal tar according to the dry distillation temperature. The coal tar obtained in coke production belongs to high-temperature coal tar. It is one of the coke oven gas purification products condensed and separated during the cooling process of raw coal gas.

[0003] The Chinese patent with the announcement number CN218076433U discloses a "coal tar distillation device". By utilizing a circulating distillation device arranged inside a distillation tower, the coal tar is returned to the top of the tower for secondary distillation after a primary distillation. Since the circulating distillation device is inside the distillation tower, the temperature of the coal tar itself will not drop during the rising process, thereby improving the efficiency of coal tar distillation and reducing the heat loss in the tower; by arranging a gathering plate connected to a vibration motor at the bottom of the distillation tower, the residual coal tar reaching the bottom of the tower can be quickly gathered at the feed inlet of the circulating distillation device to avoid sticking to the bottom of the tower and causing material loss; multiple rotatable tower plates are arranged in the tower, so that the coal tar can produce distillate to the greatest extent during the distillation process, and the scrapers arranged on both sides of the tower plates can scrape off the coal tar coked on the tower wall to reduce the occurrence of coking;

[0004] Although the above-mentioned coal tar distillation device has certain advantages in terms of distillation capacity, it is unable to adjust the feed amount. Feeding too fast will cause the liquid level to rise too fast, resulting in bubbles. The appearance of foam will slow down the progress of kerosene cleaning, increase resource consumption, increase water consumption for kerosene cleaning, affect the quality of the product, increase the power of the cleaning machine, and shorten the service life of the machine.
