The role and key points of selection of the automatic temperature control system for hydrogenation reactors

Hydrogenation reactors are widely used in the production of chemical raw materials. Various materials are dispersed and mixed through stirring, heating, and cooling to perform reaction polymerization.
The mechanical seal of the hydrogenation reactor is mainly divided into two parts: a dynamic ring and a static ring. The static ring is fixed on the top of the reactor head, and the moving ring is fixed on the stirring shaft of the reactor through bolts. Before work, the friction surface is pressed against the static ring through the bolts on the moving ring to achieve a sealing effect. If there is air leakage, use bolts to press down the movable ring until it reaches the bottom or if there is air leakage, replace the mechanical seal.
The automatic temperature control system of the hydrogenation reactor is often used to control the temperature of the reactor and reaction tank. The supporting hydrogenation reactor is usually composed of a reaction vessel, a stirrer, etc., and is heated by thermal oil. The heating speed is fast, and ordinary reactions The cauldron body and cauldron cover are made of stainless steel. The cauldron body is connected to the flange through threads. The cauldron cover is a solid flat cover. The two are tightly connected by main bolts and nuts evenly distributed in the circumferential direction. The main sealing port of the hydrogenation reactor adopts A-type double-line sealing, and other sealing points adopt the line contact sealing method of arc surface and flat surface, arc surface and arc surface, relying on the high precision and brightness of the contact surface to achieve Good sealing effect.
Pay attention to the selection of the automatic temperature control system of the hydrogenation reactor. When selecting the oil pump, you must select the model according to the flow meter. If the oil pump is too small, it will lead to uneven temperature delivery of the oil temperature machine. If the oil pump is too large, it will not increase the temperature. the cost of,
How to ensure that the temperature of the materials in the hydrogenation reactor is stable within a reasonable range during the reaction is mainly to provide enough low-temperature chilled water to the reactor. The key lies in how to choose the appropriate reactor temperature control equipment, refrigeration and heating temperature control system.
