Problems solved by technology

[0003] However, the rotary kiln cooler currently on the market has low heat recovery efficiency. Due to its large space, the heat diffuses rapidly after the air enters the cooling cylinder. As time goes by, the heat loss is large, and the equipment operation cost is relatively high.

Abstract

The invention discloses a petroleum coke material calcination cooling device. The device comprises a cylinder and rims, wherein a material inlet, a material outlet and the rims are arranged on the cylinder respectively, the material inlet and the material outlet are located at two ends of the cylinder respectively, one rim is arranged at each of two ends where the material inlet and the material outlet are located, the cylinder further comprises a cooling body connected with the material inlet, an air inlet and an air outlet are arranged on the cooling body, and the diameter of the cooling body is larger than that of the cylinder. With the adoption of the device, heat of a calcined waste coke material can be fully and effectively utilized secondarily, the energy utilization rate and the heat recovery efficiency are increased from traditionally about 20% to more than 30%, and energy is saved.

Description

technical field [0001] The invention relates to the field of oil slurry equipment, in particular to a petroleum coke calcination cooling device. Background technique [0002] The cooler is one of the important equipment in the rotary kiln system. The high-temperature materials produced by the rotary kiln often need to be cooled to a certain temperature by the cooler before they can be transported, stored and processed in the next step. According to needs, the cooler can recover a large amount of heat carried by high-temperature materials with air, so that the combustion-supporting air entering the rotary kiln can be preheated to a higher temperature to strengthen calcination and reduce heat consumption. There are many types of rotary kiln coolers. In addition to the single-cylinder coolers and multi-cylinder coolers of the rotary cylinder, there are various grate coolers suitable for bulk materials, ring coolers, vertical coolers and suitable for Boiling cooler and cyclone ...
