Embodiment 1
[0065] A schematic diagram of an oil product preparation and production device in a coal tar processing process, such as figure 1 , figure 2 shown.
[0066] The oil preparation and production device of a coal tar processing process of the present invention includes an oil distribution tank 1, an oil gas condenser 2, an oil gas trap 3, an oil distribution delivery pump 4, an oil distribution vaporization condensation cooler 5, and an exhaust gas cooling device 6 and other equipment;
[0067] The oil distribution tank 1, the oil and gas condenser 2, and the oil and gas trap 3 are integrated into one, and from top to bottom are the oil and gas trap 3, the oil and gas condenser 2, and the oil distribution tank 1;
[0068] Such as figure 2 As shown, an anthracene oil distributor 31 is provided at the upper feed port in the oil and gas trap 3, and the anthracene oil distributor adopts a feed distributor used in a chemical tower to ensure that the oil and gas into the oil and g...
Embodiment 2
[0078] As in Example 1, the outlet of the oil distribution vaporization condensing cooler 5 is connected to the oil distribution tank 1 through the return line, and the return line extends into the inside of the oil distribution tank. 11 see figure 2 As shown; the end of the pipe is sealed, and 10 irregular round holes are equidistantly opened under the pipe or side of the return pipe in the horizontal ring, and the hole diameter is 0.32 of the return pipe diameter, that is, r / R=0.32 , other with embodiment 1.
Embodiment 3
[0080] A connected pipeline is provided between the inlet and the outlet of the oil distribution vaporization condensation cooler 5 . The pipeline, the oil distribution delivery pump 4, the oil distribution tank, the return pipe and related pipelines are jointly connected to form an oil circulation circuit, and the others are the same as in Embodiment 1.

Abstract
The invention discloses a device and a process for preparing and producing oils for processing coal tar. The device comprises an oil distributing tank, an oil gas condenser, an oil gas capturer, an oil distributing conveying pump, an oil distribution gasification and condensation cooler, a waste gas cooler and the like. The process is as follows: anthracene oil is pumped to a shell side of the oil gas condenser at the upper part of the oil distributing tank, enters the oil gas capturer, then enters the shell side of the oil gas condenser from top to bottom, enters the oil distributing tank, then is mixed with medium-temperature asphalt in the oil distributing tank, and then is circulated to the oil distributing tank through the oil distributing conveying pump and the oil distribution gasification and condensation cooler; oil generated during the oil distribution sequentially passes through the oil gas condenser, the oil gas capturer and the waste gas cooler; the anthracene oil is completely recycled, and waste gas after the anthracene oil is removed is washed with gas absorber oil and then discharged into atmosphere; and the final product is conveyed to a product tank through a product conveying pipeline. The device and process thereof are simple and convenient for operation; and the obtained product has the advantages of stable quality, good product quality, high yield and nopollution during the production.
Description
technical field [0001] The invention relates to the field of coal tar processing process routes in the metallurgical coking industry, specifically, an oil product preparation production device and its production process in the middle production process of the coal tar processing device, and is suitable for the technical transformation and new construction of the coal tar processing industry in the metallurgical coking industry project. Background technique [0002] The production process of oil preparation and production in the existing coal tar processing industry at home and abroad is generally that medium-temperature asphalt and anthracene oil enter the oil distribution tank respectively, and a mechanical agitator is installed on the oil distribution tank. The medium-temperature asphalt and anthracene oil are mixed evenly. According to the quality of the oil, the input amount of the medium-temperature asphalt and anthracene oil is adjusted respectively. The oil and gas ge...
