The invention relates to a rotating drum refrigerators designed for cooling calcined coke and can be used in the coking, petroleum refining and electrode industry.

Known drum refrigerators, including mounted horizontally for rotation of the cylindrical hollow body with many compartments, provided with means for cooling [1]

The disadvantage of this refrigerator escorena object is the drum refrigerator, for cooling coke having inlet and outlet openings, a cylindrical housing mounted with a slope towards the outlet openings for rotation and provided with means for cooling and U-shaped and D-shaped cross-plates mounted on the inner surface of the housing [2]

However, this refrigerator is not enough to effectively cool the coke and characterized by abrasive wear of the housing and plates for rolling the cooled material along the plates in an inclined enclosure.

The invention is aimed at improving the efficiency of cooling of coke and reducing abrasive wear of the housing and plates.

To achieve this, the technical result in the drum fridge for cooling coke including having inlet and outlet openings, a cylindrical housing mounted with a slope towards the outlet openings for rotation and provided with means for cooling and transverse plates on the inner surface of the shell, the inner surface of the body of the last fortified with an inclination in the direction of the loading opening.

In Fig. 1 and 2 is represented schematically drum chilling the value of coke is a set with an inclination towards the outlet openings 1 rotating cylindrical body 2, on the wall is reinforced with a slope in the caretaker loading opening 3 intermittent or continuous, for example, in the form of a helical line transverse plate 4 for pouring coke. The refrigerator is equipped with means for cooling coke, for example, combs 5 for spraying coolant on the refrigerator case.

The fridge works as follows: Calcined coke with temperature up to 1450oC goes through the loading opening 3 in the body cavity 2. During the rotation of the inclined installed refrigerator cooled coke is moved to the discharge opening 1, lingering on the transversely installed the plates 4 and persipasi in the direction of travel. Excess heat coke is transferred to the plates, the body 1 of the refrigerator, and, accordingly, the cooling agent.

The slope of the transverse plates in the direction of the loading opening delay coke in the fridge longer than the reference time, which will increase the efficiency of contact and increases the heat removal and increase the efficiency of cooling of coke. In addition, limiting the rolling of coke along the plates due to the specified tilt plates will reduce abrasive wear of the housing and plates.

Drum hall, installed with a slope towards the outlet openings for rotation and provided with means for cooling and transverse plates mounted on the inner surface of the housing, characterized in that the transverse plate reinforced by the inclination in the direction of the loading opening.
