Description

Technical Field

[0001] The utility model relates to the technical field of tar, in particular to a tar stratification tank. Background Art

[0002] Tar, also known as coal paste, is a black or dark brown viscous liquid obtained during the coal distillation process. It has a special odor, is flammable and corrosive. It is a complex mixture of highly aromatic hydrocarbons. Tar is produced during the coking process of coal. Its output accounts for about 3% to 4% of the coal in the furnace. At normal temperature and pressure, its product is a black viscous liquid with a density usually between 0.95-1.10g. / cm3 and a flash point of 100℃. It has a special odor. Tar is also called coal tar. The properties of the various components of tar are different, but there are many components with similar properties. It is necessary to first use the distillation method to cut various fractions, so that the single-component products to be extracted, such as phenol, naphthalene, anthracene, etc., are concentrated in the corresponding fractions, and then further separated by physical and chemical methods.

[0003] In the process of tar treatment, coal tar needs to be transported from the storage device to the pretreatment tank through a delivery pump, and a demulsifier (polyoxyethylene polyoxypropylene polyether) and a flocculant (polyacrylamide) are added. At the same time, stirring and standing are performed to allow impurities in the coal tar to settle. Therefore, a tank body is often used. In order to achieve uniform stirring of the solution, the current tank body is usually provided with a corresponding stirring structure inside. However, the stirring structure in the traditional tank body mostly achieves stirring by only rotating to promote uniform flow of materials. Since the added material floats on the upper layer of the coal tar, a long period of stirring is required to completely mix the upper regulated material with the coal tar, resulting in low mixing efficiency and not conducive to rapid stratification of tar.

[0004] Therefore, we make improvements on this and propose a tar stratification tank. Utility Model Content

In the actual implementation process, the feed pipe 2 can be connected to an external feeding device to transport the added materials such as demulsifier (polyoxyethylene polyoxypropylene polyether) and flocculant (polyacrylamide). For some materials in the state of solid particles, water can be added in advance to melt them in liquid so that they can be transported through the feed pipe 2. The materials transported to the inside of the tank body 1 are mixed with the tar contained therein. In the process of the above-mentioned material transportation, through the setting of the liquid spraying component 6, the adjusted liquid material can be sprayed and output from the side wall to the middle of the tank body 1, so as to promote the mixing between the material and the tar. Compared with the traditional method of only adding the material above the tar and mixing it, the mixing efficiency is improved, and the transmission component 8 drives the rotation of the stirring component 7, so that it further promotes the mixing of the material and the tar, and further improves the mixing efficiency.
