Cooling water circulation system of reaction kettle

Abstract

The invention discloses a cooling water circulation system of a reaction kettle. The cooling water circulation system comprises a reaction kettle main body, wherein a reaction liner is arranged in the reaction kettle main body, a cooling chamber is arranged between the reaction liner and the reaction kettle main body, an independent reaction water heating device is arranged at the outer part of the reaction kettle main body, and comprises a main container, a single heating chamber is arranged inside the main container, a reaction water inlet pipeline is arranged above the heating chamber and communicated with the reaction liner, a cooling water drawing pipe and a cooling water inlet pipe are arranged between the main container and the cooling chamber, a one-way valve used for enabling cooling water to flow into the heating chamber is arranged between the main container and the heating cavity, and the cooling water after cooling can be recycled, so that the secondary utilization rate of resources is increased, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a cooling water circulation system of a reactor. Background technique [0002] Reactors are very common in the chemical industry. Its working principle is to mix materials and reaction water in the inner layer of the reactor for reaction. Many reactors on the market inject reaction water into the inner layer first, and heat together with the materials to accelerate the reaction. , but such a reactor has certain disadvantages. Heating the reaction water and materials together requires a large amount of heat, so the heating time is relatively long, which affects the reaction time, and there is generally a cooling process after the reaction in the reactor. The cooling process generally adopts water cooling, and the temperature of the cooling water after water cooling will rise due to the heat exchange with the reactants. have largely been rejected.
