Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a vertical polyether reactor for producing surfactants. Background Art

[0002] In the chemical industry, the production process of various surfactants (such as polyethylene oxide ether-type surfactants) may utilize vertical polyether reactors. These surfactants are mainly based on their specific chemical structure and synthesis requirements, and are produced efficiently and stably through vertical polyether reactors.

[0003] The production of polyethylene oxide ether surfactants mainly relies on ethoxylation reaction, that is, fatty alcohols, alkylphenols and other compounds containing active hydrogen react with ethylene oxide in the presence of a catalyst. This is an exothermic reaction because the breaking and formation of chemical bonds releases or absorbs energy. In order to maintain the stability of the reaction process and control the reaction temperature, the heat generated needs to be effectively removed.

[0004] In the prior art, a cooling tube is generally placed around the outer wall of the reactor, and the heat inside the reactor is transferred to the cooling water through heat conduction. The cooling water then takes the heat away to achieve a cooling effect. However, this cooling method is slow and requires the high-temperature material inside the reactor to continuously transport heat to the outside. The cooling water continuously takes away the outermost heat to achieve temperature balance of the material inside the reactor, thereby affecting the quality of the reactants and reducing production efficiency.
