Description

TECHNICAL FIELD

[0001] The utility model relates to urea production technical field, specifically related to a kind of urea production system with three-effect function. BACKGROUND

[0002] Urea is a widely used nitrogen fertilizer, its main function is to promote the rapid growth of crops, and to achieve this effect is that urea is hydrolyzed, and is decomposed into nitrate nitrogen under the action of nitrifying bacteria, and nitrate nitrogen is easily absorbed by plants. Urea is quickly decomposed when applied to soil, has high short-term fertilizer effect, and can promote rapid growth of leaves, but the utilization rate of fertilizer effect is not high, and the loss rate is too fast, so it is generally necessary to overuse. Since urea is an alkaline substance, long-term overuse of urea can cause soil compaction and affect crop growth. The urea produced by the traditional urea production device cannot solve the problems of soil compaction, inability to promote rapid root growth and rapid loss of fertilizer effect when urea is applied. SUMMARY

[0003] The urea production system with three-effect function can realize the three-effect function of the urea produced by the urea production system, i.e., loosening soil, promoting rapid root growth and inhibiting rapid loss of fertilizer effect.

[0004] The specific scheme is as follows:

[0005] The urea production system with three-effect function comprises urea solution conveying pipeline, a section of evaporator, a section of evaporator, prilling tower, conveying device, mixing drum and bin connected in sequence. The urea solution conveying pipeline is also connected to humic acid solution feeding tank and furfural acid solution feeding tank. The mixing inhibitor feeding device is provided above the conveying device and is connected to urease inhibitor feeding device and denitrification inhibitor feeding device.

[0006] The conveying device is a belt conveyor.

[0007] The urea production system with three-effect function adds furfural acid solution, humic acid solution, urease inhibitor and denitrification inhibitor feeding device in the system. The humic acid substance can improve soil, keep soil loose and prevent compaction. The furfural acid substance can promote crop root growth. The urease inhibitor can inhibit the hydrolysis rate of urea, and the denitrification inhibitor can inhibit the denitrification rate of urea, so as to keep nitrate nitrogen at a high concentration, ensure continuous promotion of crop growth and prevent rapid loss of fertilizer effect, thereby realizing the three-effect function of the urea produced by the urea production system, i.e., loosening soil, promoting rapid root growth and inhibiting rapid loss of fertilizer effect.
