As it has been described above, grain depot circulation fumigating system of the present utility model, have the advantages that
1, outside storehouse, safe and reliable:
PH in dynamic deliquescence method3Gas is reacted with the steam in air by aluminum phosphate and produces, PH3Gas formation speed is relatively slow, and the air-flow constantly produced by circulation fan operation is taken away, and rapid dispersion, in the middle of grain is piled, does not result in because of local PH3Gas concentration is too high and burns, and therefore whole dispensing process need not add CO2Also very safe；Meanwhile, dynamic deliquescence method dispensing process is directly at outside storehouse, and one storehouse of dispensing process only needs a few minutes to complete, thus being substantially improved working condition, reducing the time that operator contact with toxic gas, protecting environmental health and worker health.
2, dynamic deliquescence, efficiently quick: will thoroughly kill insect in storehouse, the PH in storehouse3Gas is necessary under finite concentration maintenance enough time, circulation fan in order that allow PH3Gas Quick uniform is distributed in each position in grain heap, it is to avoid produce PH3The concentration dead angle of gas, therefore adopts the dynamic deliquescence method can effective pest control；Meanwhile, when circulation pipe network apoplexy amount is certain, by suitable steam, control drug reaction speed, it is achieved dynamic deliquescence, get final product the PH in control loop flow tube net3Gas concentration, to optimally reach the effect of stifling insect the soonest.
3, reaction is abundant, save cost: the administration apparatus cost of dynamic deliquescence method is low, has saved PH3Generator or PH outside storehouse3-CO2The expense of mixing gas (steel cylinder dosage form)；Meanwhile, aluminum phosphate reacts with steam, and reaction is very abundant, and compared with traditional fumigation and steaming method, dosage reduces by 1/3 to 2/3.
4, easy and simple to handle: time of administration is short, only administration device as air inlet, operator need to be decreased and contact PH3, also reduce working strength simultaneously.
5, environment protecting is good: compared with natural deliquescence, dynamic deliquescence aluminum phosphate medicament complete decomposition, and in residue, undecomposed aluminum phosphate content is few, can realize aluminum phosphate residue nonhazardous discharge by simple process.
