Device for preventing conduction oil of electrical heating reaction kettle from being metamorphic

Abstract

The invention discloses a device for preventing conduction oil of an electrical heating reaction kettle from being metamorphic, and relates to the field of chemical industry production equipment. Thedevice comprises the reaction kettle, a heating tank used for heating the conduction oil and a nitrogen filling machine; the reaction kettle comprises an external kettle body and an internal kettle body, a conduction oil cavity is formed between the external kettle body and the internal kettle body, and an oil inlet and an oil outlet are formed in the side wall of the external kettle body; an oiloutlet of the heating tank is connected with the oil inlet of the reaction kettle through a pipeline, and an oil inlet of the heating tank is connected with the oil outlet of the reaction kettle through a reciprocating pump provided with a pipeline; and the nitrogen filling machine is communicated with the heating tank through a pipeline. The device can effectively prevent the conduction oil frombeing carbonized and metamorphic through modes of nitrogen filled protection, dynamic flowing and the like, and thus normal working of the reaction kettle and the product quality are ensured.

Description

technical field [0001] The invention relates to the field of chemical production equipment, and more specifically relates to a device for preventing the deterioration of heat-conducting oil in an electric heating reactor. Background technique [0002] The electric heating reactor adopts the heating method of heating the heat-conducting oil by the electric heating tube in the kettle jacket. This heating method is to insert the electric heating tube into the interlayer of the kettle jacket, and the interlayer is filled with heat-conducting oil. Pass to the raw material in the kettle. The heating system of this heating method has the characteristics of simple appearance, compact structure, and convenient operation. However, during the production process, the electric heating tube directly contacts the heat transfer oil for heating. The maximum allowable working temperature is generally about 300 degrees Celsius. If the temperature of the electric heating tube is too high, the ...
