Description

Technical Field

[0001] The utility model relates to the technical field of air heaters, in particular to an air heater for cracking reactions. Background Art

[0002] The air heater is an electric heating device that mainly heats the gas flow. The heating element of the air heater is a stainless steel electric heating tube. The inner cavity of the heater is equipped with multiple guide plates to guide the gas flow and extend the residence time of the gas in the inner cavity, so that the gas can be fully heated, the gas is heated evenly, and the heat exchange efficiency is improved. The heating element of the air heater, the stainless steel heating tube, is made by loading an electric heating wire into a seamless steel tube, filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then shrinking the tube. When current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the heating tube through the crystallized magnesium oxide powder, and then is transferred to the heated air to achieve the purpose of heating.

[0003] After a certain period of use, dust particles will more or less adhere to the outer side of the heating tube or guide plate of the existing cracking reaction air heater, which will affect the subsequent heating effect. Therefore, it needs to be cleaned every once in a while. However, the existing cleaning method generally involves disassembling the heater, which is time-consuming and labor-intensive and not convenient for large-scale cleaning. Therefore, we propose an air heater for cracking reaction. Utility Model Content
