The difference between hydrothermal kettle and reaction kettle

Hydrothermal kettle and reaction kettle are two common heating equipment in chemical production, but they have different characteristics and uses in practical applications. Understanding the difference between them helps to choose the right equipment to improve production efficiency and product quality.

1. hydrothermal kettle and reaction kettle definition and working principle

The hydrothermal kettle is mainly used for liquid heating. The liquid is heated to the required temperature by steam, which is usually used for raw material preheating and semi-preparation reaction. The reactor is a fully enclosed equipment, suitable for solid-liquid or liquid reaction, through the rotary or fixed heat transfer element to transfer heat to the reactant, to achieve continuous or intermittent reaction.

The heating method of the hydrothermal kettle depends on the steam or electric heating system, while the reactor depends on the heat transfer efficiency, usually by forced circulation or natural circulation. The heat transfer methods of the two devices are different. The hydrothermal kettle focuses on rapid heating, while the reactor emphasizes reaction uniformity and thermal efficiency.

2. hydrothermal kettle and reactor structure and composition

The structure of the hydrothermal kettle usually includes a steam generator, a steam pipe, a heating tank body, an insulation layer, and the like, where the steam generator is the core component. The reaction kettle is composed of a kettle body, a heat transfer element, a sealing system and a temperature control device. The kettle body is usually made of stainless steel to withstand high temperatures.

The design of the kettle body of the hydrothermal kettle focuses on heat preservation and sealing to reduce heat loss. The kettle body of the reactor pays more attention to the mixing uniformity of the reactants and the full transfer of heat energy, and usually adopts a spherical or conical design. The structural characteristics of the two devices determine their use scenarios and performance indicators.

3. hydrothermal kettle and reaction kettle application field

The hydrothermal kettle is mainly used for preheating and heating of liquid raw materials, which is commonly used in the raw material processing stage of chemical process. It is characterized by simple operation and high heating efficiency, suitable for small batch production. The structure of the hydrothermal kettle is compact and easy to maintain, which is suitable for laboratory and small-scale production.

Reactors are widely used in solid-liquid reactions and continuous production processes, such as pharmaceuticals, organic synthesis and other fields. The utility model has the advantages of continuous operation, high production efficiency, and is suitable for large-scale production. The structural design of the reactor focuses on the transfer efficiency of reaction heat and the stable operation of the equipment, and usually uses more complex manufacturing processes.

4. hydrothermal kettle and reaction kettle of the advantages and disadvantages of comparison

The advantages of the hydrothermal kettle are simple operation and high heating efficiency, but its capacity is limited and it is not suitable for mass production. In contrast, the reactor has higher production efficiency and scope of application, but the structure is complex and the maintenance cost is high.

The applicable scenario of hydrothermal kettle is usually raw material preheating and semi-preparation reaction, while the reactor is suitable for continuous or intermittent solid-liquid reaction. The scale of production determines the choice of equipment: small-scale production is more suitable for hydrothermal reactors, while large-scale production relies on reactors.

5. hydrothermal kettle and reaction kettle matters needing attention

When selecting equipment, it is necessary to consider the production scale, reaction conditions and equipment maintenance costs. The hydrothermal kettle is suitable for short-term use, and the reaction kettle is suitable for long-term operation. The thermal insulation material and sealing of the equipment directly affect the thermal efficiency and production stability of the equipment.

The hydrothermal kettle and the reaction kettle have their own advantages and disadvantages, and the selection of suitable equipment needs to be combined with specific production needs. The correct application of these two kinds of equipment will help to improve the efficiency of chemical production and product quality.
