Description

Drum-type petroleum coke drying equipment

Technical Field

The utility model relates to the technical field of petroleum coke, in particular to a drum-type petroleum coke drying device.

Background

Petroleum coke is black solid coke which is formed by cracking and coking vacuum residue of crude oil at 500-550 ℃ through a delayed coking device, and is a byproduct in the production of light oil products. The volatile content of the petroleum coke is about 10-18%, and the low-level heating value is more than 8000 kcal/kg. Therefore, the petroleum coke is used as solid fuel and has higher application value in the production practice of inorganic nonmetallic material products such as glass, cement, refractory materials and the like;

generally, petroleum coke after delayed coking needs to be cooled by water spray, and the cooling process directly causes the moisture content of the petroleum coke to be as high as 8-12%. The conventional drying equipment can only reduce the moisture in the petroleum coke to about 3 percent, and the high moisture in the petroleum coke is not beneficial to the grinding of the petroleum coke powder-making process and the pneumatic transmission of the petroleum coke powder in a fuel pipeline. Particularly, in winter in the north, the petroleum coke powder with the moisture content of more than 1% is easy to block a pneumatic conveying pipeline, so that the continuous combustion of the petroleum coke powder is influenced, the temperature in a heating furnace and a heating kiln is reduced, and the situations of furnace shutdown, kiln shutdown and the like can be caused seriously, therefore, a dryer is required to be adopted for drying the petroleum coke. In the production practice of petroleum coke powder making, all dryers adopt open chute sliding type feeding, and because the air in the cylinder body is discharged to the waste gas outlet, a large amount of fine particle powder can be taken away by the air flow, thus the load of a dust collector is increased; part of fine particle powder falls to the bottom of the feeding end socket, the leaked material discharge amount is about 200kg/h, the daily accumulation amount is 3-5 tons, manual cleaning is needed once every 2 hours, the labor intensity of workers is increased, and the environment is seriously polluted. In addition, the existing dryer has the problems of low heat transfer speed, low drying efficiency, poor drying effect and the like due to the structural design, so that technical personnel in related fields can improve the structure of the drying equipment and can effectively solve the problems;

in the prior art, petroleum coke drying equipment is designed into a roller type, petroleum coke materials are dried in a rolling mode, and the materials are subjected to heat exchange with hot air flow more fully, so that the moisture content in petroleum coke is reduced to below 1%, and meanwhile, the continuous production of a petroleum coke powder making process can be realized; through the sealed feeding device and the arrangement of the external heat insulation layer of the horizontal rotary cylinder, the heat dissipation loss of the drying material cylinder is reduced, the temperature of the inner wall is raised, the temperature reduction of hot gas is slowed down, and the temperature difference between the hot gas and the material is enlarged, so that the heat transfer speed is accelerated, and the heat transfer efficiency is improved;

the draught fan is installed at the air outlet to current petroleum coke drying equipment for the inside negative pressure state that forms of equipment, because the inside powdered petroleum coke that contains of petroleum coke, the powdered petroleum coke is very easily arranged to the outside air along with wind-force in the in-process of draught fan induced air, it is well known, there is the sulfur element in the petroleum coke production process, the sulfur element is the leading factor who causes the haze, if directly arrange the petroleum coke in the air, cause extremely serious influence to the air, simultaneously to petroleum coke total material, the waste of resource has just been caused to the petroleum coke powder of being discharged by the draught fan, the manufacturing cost of petroleum coke has been increased.
