Description

technical field

[0001] The invention belongs to the technical field of catalyst preparation for oil refining, and in particular relates to a drying tower with an electric heating device. Background technique

[0002] The units of the catalyst production process for oil refining are divided into raw material slurrying, spray molding, roasting, washing, filtering, drying, receiving and other units.

[0003] In the prior art, for the spray molding unit in the catalyst production process for oil refining, the drying of the catalyst requires a furnace temperature of 250°C-300°C. In the prior art, a gas-fired furnace is usually used, such as figure 1 As shown, the gas-fired heating furnace is prone to air pollution due to the exhaust gas produced, and the temperature is not easy to control; secondly, because the fuel of the gas-fired heating furnace is gas, it is easy to explode due to gas leakage when the furnace is ignited. Dangerous; again, the thermal efficiency of gas-fired ...
