Abstract
An air cooler for controlling temperature of materials at an outlet of a tube bundle is used for effectively controlling temperature of materials at the outlet of the tube bundle in a hydrogenation process during petroleum refining. The tube bundle is arranged inside a framework, and a ventilator is arranged at a position opposite to the tube bundle inside the framework. Shutters include a flash air inlet shutter and a hot air circulation inlet shutter, wherein the flash air inlet shutter is arranged on the lower portion of the framework, and the hot air circulation inlet shutter is arranged at a position horizontal with the tube bundle. A temperature control system comprises a temperature detection thermocouple, a temperature controller and a shutter opening control structure, and the temperature detection thermocouple is arranged at the outlet of the tube bundle in the air cooler. As the thermocouple is arranged in a surrounding environment of the outlet of the tube bundle of the air cooler, the temperature of the materials at the outlet of the tube bundle represents the temperature of the materials in the tube bundle. According to a control temperature value, the opening of the shutters on the sides can be regulated automatically by a driving mechanism of the temperature controller so as to control the circulation of return hot air, and accordingly the purpose of controlling temperature of the materials at the outlet of the tube bundle is achieved.
