Embodiment Construction

[0024] In order to understand the technical content of the present invention more clearly, further description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] figure 1 It is a schematic diagram of an embodiment of a spiral three-dimensional oil coke or asphalt conveying and cooling device of the present invention. like figure 1 As shown, this embodiment includes a conveyor belt 1 for transporting oil coke or asphalt. The conveyor belt 1 is arranged in a spiral three-dimensional descending manner. Connected, the bottom end is the discharge port 4, with a spiral descending inclination angle α, which is 15° compared with the horizontal plane. The conveyor belt 1 has a width of 2.5m, a length of 400m, and a conveying speed of 1.0m / s. The device also includes a lower hopper 5, which is connected to the bottom of the conveyor belt 1. The lower hopper 5 is a cylindrical container with an open upper end, has a conical bottom, and ...

Abstract

A spiral three-dimensional type apparatus for conveying and cooling oil coke or pitch, a design method therefor, and a use thereof. An existing plane-type oil coke or pitch conveying mode is changed to a spiral three-dimensional type conveying mode. One end of a conveying belt (1) is connected to a discharging pipeline (3) for oil coke (100 to 350°C) after being cooled, and the other end of the conveying belt (1) is connected to a discharging hopper (5). The conveying belt (1) is arranged in a spiral descending mode, and the spiral descending angle (α) of the conveying belt (1) ranges from 5 to 30°. A cooling water pipeline is arranged inside the conveying belt (1) to accelerate cooling molding of oil coke and pitch. The apparatus can reduce the occupied space of a molding area for oil coke or pitch, and improves the usage rate of factory unit area.

Description

technical field [0001] The invention relates to a cooling device for oil coke and asphalt, in particular to a spiral three-dimensional oil coke or asphalt conveying and cooling device, belonging to the field of oil-coal mixing oil and petroleum atmospheric / vacuum distillation. Background technique [0002] Oil coal tar is the product obtained after hydrocracking of oil and coal mixed raw materials in the slurry bed in the oil-coal mixing process, and asphalt is the product obtained after hydrocracking of vacuum residue, atmospheric residue or coal tar, etc., the yield About 5% to 40%, it is composed of aromatic compounds with more than three benzene rings, oxygen-containing, nitrogen-containing, sulfur-containing heterocyclic compounds and a small amount of high-molecular carbon substances. [0003] In the fields of oil-coal mixing oil and petroleum atmospheric / vacuum distillation, after cooling the residual coal coke and pitch at the bottom of the tower to 100-350°C, it nee...
