Rapid heating and cooling system of reaction kettle

Abstract

The invention discloses a rapid heating and cooling system of a reaction kettle. The rapid heating and cooling system of the reaction kettle comprises a supporting frame and a reaction kettle shell fixedly mounted inside the supporting frame, and further comprises a heating system and a cooling system, wherein an insulating layer is arranged on the inner side wall of the shell; the cooling systemis divided into an air cooling system, a liquid cooling system and a convection system; a reaction kettle liner is fixedly mounted at the bottom end of the inner part of the reaction kettle shell through an I-shaped component; and the reaction kettle liner comprises a kettle cover, a non-through hole connected with the kettle cover, three through holes and a non-through hole which are connected with a kettle body, and a cooling pipe and a heating body which wrap the outer surface of the reaction kettle liner. The heating and cooling system is applicable to rapid heating and cooling of a cylindrical reaction kettle with the temperature of 150-350 DEG C, is simple in structure, convenient to manufacture and relatively strong in practicability, can rapidly heat and cool the reaction kettle body, greatly saves the time of heating and cooling the reaction kettle, and improves the efficiency.

Description

technical field [0001] The invention relates to the field of reactor heating and cooling, in particular to the rapid heating and cooling of a cylindrical reactor with a temperature of 150-350°C. Background technique [0002] In some industrial production processes, a large number of heating reactors are often required. These reactors require a uniform temperature field and rapid cooling and cooling, especially for tanks that are bulky and have relatively large lengths and diameters. At present, the commonly used heating method is integrated heating, the uniformity and efficiency of the temperature field are not good, and once the heater is damaged, the entire heating function will be lost, causing serious losses to production; in the cooling process, the existing technology Usually adopt the mode of natural cooling or ventilation cooling by opening the insulation cover, the cooling mode is single, far from achieving the effect of rapid cooling.
