Descriptions
Designing a large industrial drying room is a complex project that integrates thermal,mechanical,electrical and safety.The core of the design is to achieve higheficiency,safety and energy conservation while meeting process requirements (such as temperature uniformity and heating rate).
Core design parameters
| Operating temperature | Such as room temperature-80℃,room temperature-300℃,etc. |
| Temperature uniformity | This is a key indicator to measure the performance of the drying room and is usually required to be±2℃ to±5℃. |
| Effective workspace size | Determined based on maximum workpiece size |
| Single batch processing capacity | Used to calculate the required heat energy |
| Material characteristics | Including form(powder/block),heat sensitivity,initial/final water content, etc.,directly affect the plan |
Design core systems
.House body and insulation: Color stel plates/stainless steel plates are commonly used on the inner and outer layers,and rock wool or polyurethane is filled in the middle.Overall tightness needs to be ensured.
· Heating system: You can choose electricheating(precise temperature control and clean),steam/heat transferoil(low cost,suitable forexisting boiler rooms)orgas(low operating cost,suitable forultra-high power)according to your needs.
·Air circulation system:This is the key to ensuring temperature uniformity.The mainstream adopts forced hot air circulation,and reasonably
.arranges supply/return air ducts(such as "upper and lower supply")and fans to ensure uniform coverage of hot air and avoid dead spots
.Control system:Automatic controlsystem using PLC+touch screen.The heating power is adjusted through PID algorithm,and it has multi stage program temperature control,over-temperature alarm,data recording and other functions.
.Safety protection:Overtemperature alarm and fan overload protection must be set.When handling combustibles,use explosion-proof motors/lighting and set up pressure relief ports,and ensure that electrical equipment is well grounded.
