What is the difference between reaction kettle and hydrothermal kettle

In chemical production, the reactor and the hydrothermal reactor are two kinds of commonly used reaction equipment, which are significantly different in principle, structure, applicable scenarios and so on. Understanding the difference between these two types of equipment can help you choose the right equipment for a specific production task.

1. equipment structure and working principle of different

1. Structure and working principle of reaction kettle The reactor is usually composed of a reaction vessel, an insulation layer, a feed port and an exhaust port. The insulation layer is made of glass fiber or rubber material, which can effectively isolate the external heat and ensure the temperature control during the reaction. The working principle of the reaction kettle is to heat or cool the liquid in the reaction vessel to make the reactants chemically react at a constant temperature and pressure. Due to the effect of the insulation layer, the temperature of the reactor is usually controlled between 50°C and 100°C.

2. Structure and working principle of hydrothermal kettle The core of the hydrothermal kettle is a constant temperature water bath filled with water and insulation materials. The working principle is to transfer heat to the reactants in the reaction vessel by heating the water in the water bath. The temperature range of the hydrothermal kettle is typically between 100°C and 300°C, which is suitable for reaction conditions requiring higher temperatures. Due to the internal water circulation, the temperature distribution of the hydrothermal kettle is more uniform, which is suitable for occasions that require long-term constant temperature.

Introduction: reaction kettle and hydrothermal kettle in chemical production applications are different?

2. applicable scenarios are different

1. Applicable scene of reaction kettle Reactors are often used for chemical reactions that require strict control of temperature and pressure, such as polymerization, esterification, etc. Due to its small temperature control range, it is usually suitable for materials that are sensitive to the reaction temperature, such as synthetic rubber and polymer materials. The reactor is also suitable for occasions requiring intermittent operation, which is convenient for control and management in the production process.

2. Applicable scene of hydrothermal kettle Hydrothermal kettles are suitable for reaction conditions that require sustained high temperatures, such as protein purification, enzymatic reactions, and the like. Due to its large temperature control range, it is suitable for handling high viscosity and large molecular substances. The hydrothermal kettle is also commonly used for high temperature reaction experiments in the laboratory because of its simple operation and reliable equipment.

3. operating conditions and materials are different

1. Operating conditions of the reactor The operating temperature of the reactor is usually between 50°C and 100°C, which is suitable for medium and low temperature chemical reactions. During the operation, care should be taken to avoid excessive temperature leading to decomposition of reactants or side reactions. The material of the reactor is usually stainless steel or carbon steel to ensure corrosion resistance and high temperature stability.

2. Operating conditions of hydrothermal kettle The hydrothermal kettle can be used in a wider range of temperatures, usually between 100°C and 300°C, and is suitable for high temperature reactions. Due to the design of the water circulation system, the temperature distribution of the hydrothermal kettle is more uniform, which is suitable for scenarios that require constant temperature reactions. The material selection of the hydrothermal kettle is similar to that of the reaction kettle, but sometimes special materials are used to improve the high temperature performance.

4. summary: choose reaction kettle or hydrothermal kettle?

When selecting chemical reaction equipment, it is necessary to decide whether to use a reaction kettle or a hydrothermal kettle according to specific production requirements. If the temperature and pressure need to be strictly controlled, and the reaction temperature is low, the reactor is a more suitable choice. However, if a continuous high temperature reaction is required and the temperature control range is large, the hydrothermal kettle is a better choice. By deeply understanding the characteristics of these two types of equipment, chemical industry technicians can better optimize the production process, improve reaction efficiency and product quality.
