Abstract

The invention provides a method for cooling a compound fertilizer to solve the problems of the prior compound fertilizer cooling method of large occupied area of the used device, high energy consumption and low cooling efficiency. The high-temperature compound fertilizer product is sent to a first fluidized bed cooler by a conveyor; high-pressure normal temperature air is blown by a first fan so that the high-temperature compound fertilizer product is boiled on the first fluidized bed; and the heat exchange of the high-temperature compound fertilizer product with the normal temperature air isrealized on the first fluidized bed sufficiently.

Description

Technical field: [0001] The invention relates to a method for cooling high-temperature compound fertilizer products by using air as a medium. Background technique: [0002] The cooling of traditional compound fertilizers generally uses natural air as the medium, and the fertilizer is contacted with the air through rotating cylinders, induced draft fans and other equipment to achieve the purpose of heat transfer and cooling of the fertilizer. The disadvantage of this method is that the scale of the equipment is large and the area occupied is large. The rotary cylinder of the main equipment generally weighs tens of tons and has a length of 20 to 30 meters, which consumes a lot of energy. The heat transfer efficiency is low and the cooling effect is poor. It is impossible to cool the material below the natural ambient temperature. Invention content: [0003] The purpose of the present invention is to provide a compound fertilizer cooling method with less equipment investme...
