Problems solved by technology

That is, since tar must be heated to a temperature not necessarily higher than the temperature used to separate naphthalene, there arises a problem that a burden is generated in the distillation process, and energy consumption is as large as the generated burden

Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, this invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0036] The present invention relates to an additive to be added in manufacturing coke, and more particularly to a distillation apparatus for manufacturing an additive to be used as a caking additive and additive manufacturing equipment including the distillation apparatus. The produced additive (caking additive) is added to the raw material for coke production, namely the coal mixture. For example, the additive is added to a coal mixture as a caking additive, wherein weak coking coal having low...

Abstract

The present invention relates to a distillation apparatus for fractionating impurities from a raw material by a fractional distillation method using a boiling point difference to modify the raw material, the distillation apparatus comprising: a reactor having an internal space capable of heat treating the injected raw material and moving the separated impurities; and an impeller installed in a lower part of the reactor and including a blade rotating while supplying hot air into the reactor. Thus, according to an embodiment of the present invention, since the hot air is supplied while the impeller is rotating, the hot air, which is a heat source, can be uniformly transferred to the inside of the distillation apparatus. As a result, the raw material, which is an object to be treated, uniformly contacts the hot air, which is a heat source, thereby improving the separation efficiency of impurities. Therefore, since the content of impurities is low, a high-quality additive can be manufactured.

Description

technical field [0001] The present invention relates to a distillation apparatus and an additive manufacturing facility including the distillation apparatus, and more particularly to a distillation apparatus and an additive manufacturing facility including the distillation apparatus to facilitate discharge of manufactured additives. Background technique [0002] To make coke, a caking additive is added and mixed with a coal mixture mixed with various coals, and the mixture is loaded into a coke oven and dried. Here, caking additives are used to increase the strength of the coke by increasing the charge density of the coal mixture as it is loaded into the furnace. This method is used to use tar or a caking component extracted from coal and use it as a caking additive. [0003] However, the use of tar as a caking additive causes odor and puts a load on post-processing, so it is difficult to produce normal coke. These problems originate from coke oven light oil and naphthalen...
