Problems solved by technology

[0004] The heat dissipation efficiency of urea particle size in the air is low. The current urea particles are affected by the dust recovery equipment of the urea prilling tower, and their temperature will rise by about 10°C. In summer, the temperature of the urea particles after leaving the prilling tower can reach 70°C. As the temperature of urea particles increases, the strength of urea particles will greatly decrease, which will affect the quality of urea particles, and it will be easy to pulverize and generate a large amount of urea dust, which is not conducive to the protection of the surrounding environment.

Abstract

The invention discloses a high-temperature granular urea rapid cooling process and urea particle cooling equipment. The urea particle cooling equipment comprises a feeding bin, a cooling cover, a discharging bin, a bearing plate, a baffle plate, a heat exchange plate and a communicating pipe, wherein a first flange is arranged on one side of the outer wall of the lower end of the feeding bin, and the feeding bin is connected with the cooling cover through the first flange; and a second flange is arranged on one side of the outer wall of the lower end of the cooling cover, and the cooling cover is connected with the discharging bin through the second flange. According to the high-temperature granular urea rapid cooling process and the urea particle cooling equipment, by arranging the bearing plate, the heat exchange plate and the communicating pipe, the effect of conveniently cooling urea particles is achieved, the discharging speed of the urea particles is adjusted, it is guaranteed that the urea particles make uniform contact with the heat exchange plate, the cooling integrity of the urea particles is guaranteed, and the cooling efficiency of the urea particles is improved.

Description

technical field [0001] The invention relates to the technical field of urea particle cooling, in particular to a high-temperature granular urea rapid cooling process and urea particle cooling equipment. Background technique [0002] Since the production process of urea is relatively complicated, and its production process is a process of chemical reaction, it will be affected by various factors during the production process, resulting in unbalanced quality parameters. The quality of urea is mainly measured by indicators such as nitrogen content, biuret content, water content, particle size, strength and dust. Among these indicators, only the nitrogen content can be effectively controlled through the production process, but other various These indicators will be affected by factors such as temperature in the production process, reaction time, equipment operation status and external environment, which will have varying degrees of impact on product performance. [0003] After ...
