On this basis, the invention provides a numerical simulation method for performing catalyst particle heating by utilizing the multi-chamber rotary furnace. Computational fluid dynamics software CFX is adopted to perform numerical computation on a heating process of catalyst materials in the gas multi-chamber rotary furnace and an accompanying heat transfer process, so that high cost and technical risks caused by experiments or blind design are avoided to a certain extent; and the method is of a certain guiding significance for actual operation conditions of the multi-cavity rotary furnace.

Description

technical field [0001] The invention relates to a heating furnace device and a heating furnace parameter simulation method, in particular to a rotary furnace device and a heating furnace working parameter simulation method, which are applied in the field of catalyst production and preparation devices and process technology. Background technique [0002] The petroleum and chemical industry is one of the most basic and largest three pillar industries in contemporary society, and it is closely related to the energy and material industries. Catalysts play a very important role in the petroleum and chemical industries. Catalyst heating is an integral process in its production, which can be done in a rotary kiln. For coal-fired industrial furnaces, small and medium-sized enterprises in my country generally use direct coal combustion to provide heat sources for industrial furnaces. The main problem in this combustion process of coal is that the increase, decrease and distribution...
