China manufacture steam heating rotary dryer energy saving rotary steam tube dryer
Model Number:
- RSTD
The rotary steam tube dryer is large drying equipment which can indirectly heat the wet materials by the saturatedsteam in the multi-row steam tubes inside the cylinder body. It can be mainly used for the drying of large quantitiesof powder, granular, cake -like materials.
The characteristics of the airflow tube coal drying technology are as below. (1). the large drying strength: because of the high air velocity, the particles are well dispersed in the gas phase, it can put the entire surface area as the effective drying area; (2). the drying time is short: the contact time between the two phrases of gas and solid is short, it is generally dried in 0.5-2 seconds or for a maximum of 5 seconds; (3). the thermal efficiency is high. The higher the airflow drying gas inlet temperature, the higher the thermal efficiency and it is generally above 60%; (4).The processing amount is large; (5). the equipment is simple. Airflow tube dryer has simple structure and occupies less area. It requires little investment and is easy for automatic control; (6). The application range is wide. Airflow tube drying can be used for all kinds of powder and granular materials.
The rotary dryer with flue gas as the heat medium is a conventional coal drying technology, and widely used in drying various coal property and coal slime. The Drying Engineering Center makes technological advances and upgrades to the traditional technology and develop technology of rotary drying with closed circulating inert gas, which not only maximizes the reduction of operating cost, but also uses patented sealing technology to seal inlet and outlet of the dryer, the system is in full closed operation, safety and environment friendly. The technology has been applied in the first section drying system of coal catalyst for Shenhua coal oil device and runs well.
| Technical advantages | Complete equipment scale, many industrialized applications, low comprehensive operating cost, large market share; It is superior to the products of international counterparts in terms of technical safety and energy saving. |
| Scientific research results | Obtained 27 invention patents, 18 utility model patents, 4 US invention patents, and 2 Japanese invention patents; Formulated the industry standard "Steam Heating Tubular Rotary Cylindrical Dryer" HG/T3914-2006 |
| Scope of application | Coal, sludge, crude terephthalic acid (CTA), polycarbonate (PC), purified terephthalic acid (PTA), isophthalic acid (PIA), high-density polyethylene (HDPE), polyphenylene ether (PPE/PPO) ) Copper concentrate, lead concentrate, sulfur concentrate, etc. |
| Type | Indirect heat exchange drying equipment |
| Improvement | The difference from the conventional rotary drum dryer is that the steam heating tube is installed in the drum |
| Appearance description | The inlet and outlet ends of the material have a special sealing structure. The heating tube runs through the entire drying machine and is arranged in a number of concentric circles (generally 1 to 6 circles). The heat required for drying is mainly provided by the heating tube. |
| Structure | from the barrel (including shell steam pipe steam distributor and hammer) inlet and outlet screw, inlet and outlet end sealing, steam distribution system, transmission system (including reducer motor gear, supporting roller and rolling ring) and lubrication system composition. |
