Embodiment Construction

[0018] Such as figure 1 as shown, figure 1 It is an intelligent control method for anti-caking in the process of urea storage proposed by the present invention.

[0019] refer to figure 1 , the anti-caking intelligent control method in the urea storage process proposed by the present invention includes:

[0020] S1. Keep the temperature in the storage room within the preset temperature range, keep the humidity within the preset humidity range, and keep the amount of dust within the preset dust range;

[0021] In this embodiment, the preset temperature range, preset humidity range, and preset dust range are all set according to empirical values; thus, the interference caused by environmental factors to the caking problem in the urea storage process can be effectively avoided, Improve the validity and pertinence of the research results of this system.

[0022] S2, dividing the storage room into n test areas;

[0023] In this embodiment, the length, width, and height of the ...

Abstract

The invention discloses an anti-caking intelligent control method used in a urea storage process. The anti-caking intelligent control method comprises the following steps: S1, maintaining temperaturein a storage chamber to be in a preset temperature range, maintaining humidity to be in a preset humidity range, and maintaining dust volume to be in a preset dust volume range; S2, dividing the storage chamber into n test areas; S3, conveying urea to the n test areas, wherein urea stacking heights in the n test areas are different respectively and are H1, H2, H3...Hn sequentially; and S4, respectively acquiring urea caking rates of the n test areas after preset time t and analyzing, and selecting the best stacking height based on an analysis result. The anti-caking intelligent control methoddisclosed by the invention has the advantages that balanced relation between the stacking height and pressure is found, and the best stacking height is selected, on the one hand, the condition that alarge amount of urea is caked as the stacking height is too high and the pressure is too high can be avoided, and on the other hand, the condition that storage space is wasted as the stacking height is too low also can be avoided, so that urea storage effect is maintained while maximum storage rate is maintained.

Description

technical field [0001] The invention relates to the technical field of urea storage control methods, in particular to an intelligent control method for preventing caking during urea storage. Background technique [0002] For solids that are soluble in water, they are not absolutely dry when they touch the surface of moist air, but are covered with a very thin solution film, and the concentration of the solution on the liquid film is equivalent to the saturated solution concentration at that temperature. During the storage, transportation and stacking of urea, the surface of the granules is in close contact; as the temperature of urea granules and the humidity of the surrounding air change, the process of moisture absorption or evaporation occurs on the surface of the granules, which leads to the breaking of the granules, and the particles will be on the surface under the extrusion of the outside world. Recrystallization occurs in the liquid film. The newly crystallized urea...
