Abstract
The invention discloses a nitrogen gas adjusting method for a squat silo, which is used in the technical field of nitrogen gas adjusting for grain storage. The invention can simplify the equipment and the nitrogen charging process control and the use operation, and effectively reduce the nitrogen charging cost.
Description
Technical Field
The invention belongs to the technical field of grain storage nitrogen gas regulation, and particularly relates to a nitrogen gas regulation method for a squat silo.
Background
In the storage process of the grains, a nitrogen gas adjusting technology is adopted, and various methods such as upper charging and lower discharging, lower charging and upper discharging, standing in the nitrogen charging process and the like are used, so that the equipment and the nitrogen charging process are controlled and used and operated complicatedly, the nitrogen charging time is long, the energy consumption is high, and the nitrogen charging cost is increased. The upper-charging and lower-discharging nitrogen gas adjusting method is used, so that the equipment device, the nitrogen charging process control and the use operation are simplified, and the nitrogen charging cost is effectively reduced.
Disclosure of Invention
The invention aims to solve the problems that the prior art is improved, a squat silo nitrogen gas adjusting method is provided, and the problems that the existing nitrogen gas adjusting method is complex, high in energy consumption and high in nitrogen filling cost are solved.
The nitrogen gas regulating process includes filling nitrogen gas from the upper space of the grain bin to the top of the grain pile, pumping out gas from the bottom of the grain pile, stopping pumping out the gas from the bottom of the grain pile, and stopping filling nitrogen gas after the nitrogen gas pressure reaches the target value.
When the nitrogen gas adjusting process is applied to grain protection, the target value of the nitrogen concentration in the grain pile is 95%.
When the nitrogen gas adjusting process is applied to insect killing, the target value of the nitrogen concentration in the grain pile is 98%.
The target value of the nitrogen pressure in the grain pile in the nitrogen controlled atmosphere process is 60Pa.
The nitrogen gas adjusting process is implemented by pipeline connection, wherein the pipeline connection comprises a nitrogen gas inlet pipeline connected with a circulating pipe at the upper part of the granary, and a nitrogen gas outlet pipeline connected with a collecting pipe at the lower part of the granary.
Drawings
FIG. 1 is a schematic diagram of a nitrogen gas-regulating structure according to the present invention;
FIG. 2 is a schematic diagram of nitrogen gas conditioning operation according to the present invention;
in the figure: 1. a nitrogen inlet pipeline; 2. a shallow round barn; 3. a circulating pipe at the upper part of the granary; 4. grain bulk; 5. the upper space of the granary; 6. a left circulating pipe at the lower part of the granary; 7. the right circulating pipe is arranged at the lower part of the granary; 8. a collecting pipe at the lower part of the granary; 9. a nitrogen outlet pipeline.
Detailed Description
As shown in fig. 2, during nitrogen regulation, nitrogen gas passes through a nitrogen gas inlet pipeline 1, passes through a grain bin upper circulating pipe 3, enters a grain bin upper space 5, passes through a grain stack from the top of the grain stack 4, passes through a grain bin lower left circulating pipe 6 and a grain bin lower right circulating pipe 7 from the bottom of the grain stack 4, passes through a grain bin lower collecting pipe 8, and is discharged through a nitrogen gas outlet pipeline 9.
Claims (4)
