Finned Tube Steam Heat Exchanger in Industrial Drying

Finned Tube Steam Heat Exchanger in Industrial Drying

The finned tube steam heat exchanger uses steam as the heat medium. The steam flows inside the tube and transfers the heat to the fins outside the tube through the tube wall. As the fins increase the heat dissipation area, the heat is transferred to the surrounding air more efficiently, and the air is heated to form a hot air stream, which is used to dry the object to be dried. The hot airflow exchanges heat with the surface of the object to be dried, so that the moisture and other volatile components in the object absorb the heat and evaporate, thus achieving the purpose of drying.

Advantages

Efficient heat transfer: the existence of fins greatly increases the heat transfer area of the heat exchanger, which can effectively improve the heat transfer efficiency and shorten the drying time, and the heat transfer efficiency can be increased by about 20% - 30% compared with that of the common tube-type heat exchanger.

Compact structure: under the same heat transfer area requirement, finned tube steam heat exchanger is smaller in size, occupies less space, saves industrial space and is easy to be installed in various drying equipments.

Strong adaptability: according to different drying process requirements, the shape, size, spacing and number of tube rows of fins can be flexibly adjusted to meet different heat transfer needs and drying effect, and can be adapted to a variety of materials and different drying environments.

Stable operation: steam as a heat medium, with a stable temperature, pressure is easy to control the characteristics of the finned tube steam heat exchanger in the drying process can maintain a stable heat supply to ensure the consistency of drying quality.

Energy saving and environmental protection: through reasonable design and optimization, finned tube steam heat exchanger can make full use of the heat energy of steam, reduce heat loss, reduce energy consumption, and realize energy saving and emission reduction while improving drying efficiency.

Application Scenario

Wood drying: In the wood processing industry, finned tube steam heat exchanger can be used in wood drying kiln. Steam is passed into the heat exchanger, and the heated air is circulated in the drying kiln, so that the moisture in the wood evaporates uniformly, effectively preventing deformation and cracking of the wood, and improving the drying quality and processing performance of the wood.

Food drying: In food production, such as vegetable dehydration, fruit drying, grain drying, etc., finned tube steam heat exchanger can provide stable heat source for drying equipment. By precisely controlling the temperature and wind speed, it can quickly remove the water in the food and prolong the shelf life of the food under the premise of ensuring the nutrients and taste of the food.

Textile printing and dyeing drying: In the textile printing and dyeing industry, fabrics need to be dried after dyeing. Finned tube steam heat exchanger is installed in the drying box or drying channel, the hot air produced to dry the fabric, so that the dyes are better fixed in the fabric, while ensuring the smoothness and color uniformity of the fabric.

Chemical raw materials drying: for various chemical raw materials, such as plastic granules, rubber products, fertilizers, etc., finned tube steam heat exchanger can provide suitable drying temperature and airflow speed according to the characteristics of chemical raw materials and drying requirements. It can effectively remove the water and solvent in chemical raw materials, improve the purity and stability of chemical raw materials, and meet the requirements of the subsequent production process.

Building materials drying: in the production of building materials, such as gypsum board, brick and tile, ceramics and other drying process, finned tube steam heat exchanger plays an important role. It can provide high temperature hot air for the drying equipment, accelerate the evaporation of moisture in the building materials, improve the strength and quality of building materials, and shorten the production cycle.
