1. Process Introduction

The chemical reaction in a reactor usually needs to be carried out within a certain temperature range to ensure the smooth progress of the reaction and the accuracy of the experimental results. Both high and low temperatures can lead to unstable reactions or deviations in experimental results. Therefore, precise temperature control is of great significance for ensuring the smooth progress of experiments and the reliability of results. As a temperature control equipment, chillers are widely used in the temperature control process of reaction vessels. The chillers produce cold energy through refrigerant circulation, and then transport the cold energy to the jacket of the reaction vessel through a refrigerant carrier, carrying out the heat in the reaction vessel and achieving temperature control of the reaction vessel. During the reaction process, the chiller adjusts the refrigerant flow rate to keep the reactor within the set temperature range. The refrigerant is compressed into a high-temperature and high-pressure gas in the compressor, and then transported to the condenser. In the condenser, the refrigerant transfers heat to cooling water or air and condenses into a liquid. After passing through the throttle valve, it enters the evaporator to evaporate and absorb heat, becoming a gas that is then sucked in again from the suction port of the compressor, completing a cycle. The temperature range is adjustable from -150 ℃ to+300 ℃.

2. Connection between chiller and reactor

The reactor and chiller are usually connected through pipelines, including pipeline connections and sealing requirements. The pipeline connection needs to ensure the sealing and pressure resistance of the pipeline to prevent refrigerant leakage and pressure loss. The sealing requirement needs to ensure good sealing at the pipeline connection to prevent refrigerant leakage and air entry.

Pipeline connection:

The pipeline connection between the reactor and the chiller needs to use high-quality pipeline materials that are resistant to pressure, corrosion, and high temperature to ensure the reliability and stability of the connection. At the same time, pipeline connections need to be made using specialized methods. Pipeline connectors and sealing materials are used to ensure the sealing and pressure resistance of the connections.

Sealing requirements: 

The pipeline connection between the reactor and the chiller must meet strict sealing requirements, including the sealing performance at the pipeline connection and the pressure resistance of the pipeline itself. To meet these requirements, it is necessary to use professional sealing materials and connectors, and conduct strict sealing testing and inspection.
