Bulk Solids Heat Exchanger

Bulk Solids Heat Exchangers have a modular product structure and are based on the laser welding pillow plates. These pillow plates are assembled into one or more plate packs, between which the bulk solids flow and are cooled or heated depending on the dut

Description

Main Applications for Laser Welded Pillow Plate

Unlike conventional drying and conditioning technologies, which blow hot air through the product to heat up and/or remove moisture; Shineheat uses a combination of their advanced plate heat exchange technology (providing an indirect heat source) and blow dry air to remove the moisture. This approach greatly reduces air-flow requirements and returning much better efficiencies and improved process control.

How does a bulk solids
heat exchanger work?
Bulk solids are distributed over the pillow plates in a hopper, in which a level indicator is used to measure the fill level and flow rate. To ensure that the bulk solids are heated to a uniform temperature, an even flow must be achieved across the entire surface of the heat exchanger. This even mass flow is created by means of an outlet designed especially for this purpose. As a result, every particle of the bulk solids flows through the heat exchanger at the same rate and are consequently in contact with the pillow plates for the same length of time. A temperature sensor in the product outlet ensures that the bulk solids are at the temperature required as they leave the heat exchanger.

Given the above, the heat exchanger consists of just two independent control loops: one for the mass flow of the bulk solids and one for the temperature of the bulk solids. This results in a system that is easy to operate and control.

Product Advantages:

1. World leading laser welding pillow plate heat exchange technology:

Pillow plates are made by laser welding two plates all around as well in the middle area creating "weld flowers". After the forming process, the inner part of the heat exchange plate forms a pillow type cavity. The pillow plate design creates excellent turbulence and provides a self supporting structure.

2. Full closed operation with zero emission:

By using our pillow plate technology for bulk solid heat exchanger applications no direct air will be in contact with the bulk solid. So it fundamentally eliminates dust, fine particles and odor emissions, as well as prevent dust explosion risks.

3. Saves energy up to 90%:

Compared to traditional heat transfer technology for bulk solids our heat exchangers do not require fans powered by electric motors and therefore in some cases the energy consumption of powder flow heat exchangers is decreased by close to 90%.

4. Ensure superior product quality:

Controling the velocity when the powder passes through the heat exchanger can effectively prevent decomposition of the product as well prevent wear and tear of the product ensuring that the particle properties, such as crystal shapes, remain and therefore achieve the best product quality.

5. Even heat exchange efficiency:

Based on the "dense phase conveying" principle, powder in the heat exchanger flows evenly at low speed, which ensures an even temperature of product discharging.

6. Modular structure, easy to expand:

The vertical structure of SV bulk solid is compact and modular. The processing amount could be adjusted by increasing or decreasing pillow plate quantity. It saves lots of installation space.

7. Compact structure, easy to install

The "wall type heat exchange" and "dense phase conveying" designs mean there is no need of high power consuming equipment, such as electric motors, fans, dust catchers and emission control systems.
