Problems solved by technology

In this way, the molten salt will flow to the electric heating element outside along the furnace wall, causing damage to the heating element and loss of molten salt. In addition, when adding molten salt, it is often in a high-temperature molten state , It is also easy to cause molten salt to splash and hurt people

Abstract

The invention provides a molten salt heating furnace for reaction of a catalyst. The molten salt heating furnace is characterized in that an inner cavity of the molten salt heating furnace is divided into an inner cavity main body and an inner cavity outlet; the inner cavity main body is cylindrical; the inner cavity outlet is in an annular arc shape which is inwards concaved and gradually contracted from top to bottom; the bottom part of the inner cavity outlet is the same as the main cavity main body in inner diameter and is fixed with the inner cavity main body in a welding manner, and the end surface of the bottom part of the inner cavity outlet is smaller than the end surface of the top part of the inner cavity outlet; a heating module is formed by winding electric heating tubes which are the same in diameter along the outer wall of the inner cavity main body; the outer surface of a heating furnace shell is made of stainless steel. The molten salt heating furnace provided by the invention has the beneficial effects that the inner cavity outlet is designed in the annular arc shape which is inwards concaved and gradually contracted from top to bottom, so that a wall climbing phenomenon is effectively prevented from happening, further the damage to the electric heating elements winded on the outer wall of the inner cavity is avoided, and the service life of components is prolonged, the cost is reduced, and good economic benefit is obtained.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a molten salt heating furnace for catalyst reaction. Background technique [0002] Since the molten salt heating furnace can heat the powdered molten salt to a melting point above 142°C under normal pressure, the maximum working temperature can reach a high temperature of 580°C, which is better than that using steam or heat-conducting oil as the main heat-conducting medium. Therefore, it is widely used in chemical production industry. At present, most of the vertical molten salt heating furnaces used in the small test reaction of catalysts are designed in the shape of a straight barrel. The molten salt will wet the wall upwards along the wall in the molten state, and when the wetted top of the wall is also After soaking, it will flow downward along the outside of the wall, which is the so-called "wall climbing phenomenon". In this way, the molten salt will flow to the...
