Embodiment Construction

[0010] In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings.

[0011] A distillation unit for producing diesel oil from coal tar, such as figure 1 As shown, it includes a bracket 8 and a casing 7 with an oil inlet 1 and a steam outlet 6 fixedly connected thereto, and the steam outlet 6 is fixedly connected with a condenser 5 through a connecting piece 4 (such as a conduit), and the casing The bottom end of 7 is provided with a slag outlet 9, and the upper end of the housing 7 is provided with an additive port 2. Before the fuel oil is fractionated to distill diesel oil, additives are added to the fuel oil through the additive port 2, and the fractionated diesel oil passes through the steam outlet 6. Discharged, condensed and recovered under the action of condenser 5. During the fractionation process, the temperature of the...

Abstract

The invention relates to a distillation apparatus for producing diesel oil from coal tar. The distillation apparatus comprises a bracket and a shell which is fixedly connected with the bracket and is provided with an oil inlet and a steam outlet, wherein the bottom end of the shell is provided with a slag outlet; the upper end of the shell is provided with an agent adding port; and a thermometer is arranged in the steam outlet. Before the diesel oil is distilled from fuel oil, an additive is added into the fuel oil through the agent adding port, so the color keeping time of the distilled diesel oil can be prolonged; other additives are not required to be added into the distilled diesel oil; and the production efficiency is effectively improved.

Description

Technical field: [0001] The invention relates to a diesel oil preparation device, in particular to a distillation device for producing diesel oil from coal tar. Background technique: [0002] At present, when coal tar is used to produce diesel oil, the diesel components in coal tar are generally refined first, and then additives are added to it to prepare qualified diesel oil. However, the diesel oil produced by this method has a short color retention time, and the refining and blending are carried out in different containers, so the production efficiency is low. Here it is the weak point that existing technology exists. Invention content: [0003] The technical problem to be solved by the present invention is to provide a high-efficiency distillation device for producing diesel oil from coal tar aiming at the deficiencies in the prior art. [0004] This scheme is realized through the following technical measures: the distillation device for producing diesel oil from coa...
