The petroleum coke dryer equipment is mainly composed of a heat source device, a feeding and feeding device, a drying host, a discharging system, a dust removal system, and a control system. The petroleum coke that needs to be dried is mainly in the discharging area and the inclined lifting plate area. , cleaning area, drying area. The materials containing more than 90% water content can be dried to the finished product at one time.
Performance Advantage
1. Combined lifting plate
According to the change of the physical properties of the material during the drying process in the petroleum coke dryer, a combination of lifting plates with various structures is used to make the material form a uniform material curtain in the cylinder, and conduct sufficient heat and mass transfer with the hot flue gas. , For high-humidity viscous materials, there will be a chain breaking device to prevent clogging and block materials and break the accumulation ball. For materials with excellent fluidity, spoon-shaped arc plates are used. As a result, the evaporation intensity per unit volume can reach 40～80kg/m3.h, and the evaporation intensity is 50～80% higher than that of the traditional coke dryer.
2. Self-aligning roller device
The petroleum coke dryer adopts a bearing type and structure that is different from the traditional coke dryer supporting roller. The supporting roller and the belt are self-restrained to maintain linear contact, and the friction surface contact is wider and balanced, ensuring the service life of the supporting roller and the belt. , which enhances the stability of the cylinder operation. And appropriately reduce the angle between the supporting rollers, reduce the running resistance, and reduce the power consumption.
3. Reasonably adjust the speed
According to the different physical and chemical properties of the drying materials, the residence time of drying is different. The design adopts ideal rotation speed to fully guarantee the drying quality. Generally, electromagnetic speed regulation or frequency conversion speed regulation motor is used.
4. Dust collection tail cover design
According to the requirements of different drying materials, the petroleum coke dryer expands the cavity to design the tail cover and change the exhaust flow direction, so that the tail cover can take the primary dust collection effect, which greatly reduces the dust collection pressure of the subsequent dust collector.
5. New sealing device
The front and rear sealing rings of the petroleum coke dryer draw on the sealing device of the rotary kiln, and are composed of a labyrinth device, which is resistant to temperature and wear, has good sealing effect, long service life and convenient installation and maintenance.
