Abstract
The utility model relates to a high-efficiency fumigant generator and a delivery and dispensing device. The utility model is provided with a PH3 [3] measuring generator, a constant volume dilution delivery and dispensing device and an on-line inspection and real-time controller, wherein, the PH3 [3] measuring generator is composed of a metering pump reactor, the constant volume dilution delivery and dispensing device is composed of a mixer of a filter and a venturi suction pump, and the on-line inspection and real-time controller is composed of a central control processor, wherein, the reactor in the PH3 [3] measuring generator is connected with the mixer interface of the mixer of the filter in the constant volume dilution delivery and dispensing device through a tube of the reactor, and the signal terminals of the on-line inspection and real-time controller are respectively connected with the signal ports of the PH3 [3] measuring generator and the constant volume dilution delivery and dispensing device.
Description
The utility model relates to a speciogenesis, preparation and past reserve storage, particularly carries PH toward the deposit silo
3Air Mixture or PH
3The device of insect protected such as nitrogen mixture, desinsection fumigant.
The general PH that uses of reserve storage fumigant with certain proportioning
3With the gaseous mixture of other gas, fumigant both can on-the-spotly take place, also can be in the plant produced can in high-pressure cylinder.
Original on-the-spot generation technology is directly to throw in aluminum phosphide tablet in the warehouse, its basic principle is: aluminum phosphate is met the rapid hydrolysis of minor amount of water, and discharge have insect protected, the phosphine gas of insecticidal effect, in order to reduce the hydrolysis rate of aluminum phosphate, reach the purpose of slowly-releasing, in aluminum phosphide tablet, generally add additives such as dolomol, paraffin.This technology exists regional area concentration higher and have certain zone to become the phenomenon of " blind area ", does not reach best insect protected, insecticidal effect; Simultaneously, hydrolysate Al (OH)
3, additive and the residual of unhydrolysed aluminum phosphate be pollution source to grain; And this technology is only applicable to pile high less warehouse, and is not suitable for the high bigger warehouse of heap.
In order to address this problem, common way is to adopt PH on the basis of re circulation fumigation
3/ CO
2Steel cylinder mixes gassiness venting technology, and the employing of this technology has solved some existing problems of tablet dispensing preferably.But, PH
3/ CO
2Mixed gassiness production of steel cylinder and cost of transportation are higher, and CO
2Gas is as greenhouse gases, and its a large amount of uses will inevitably cause environment damage, therefore, is difficult to implement this operation for general reserve storage.
The purpose of this utility model is to provide a kind of novel fumigant to take place and transportation and distrubution apparatus like this, and it can accurately measure generation, preparation, carry the PH that is used for stifling large-scale reserve storage insect pest
3Air Mixture or PH
3Fumigant such as/nitrogen mixture.
The purpose of this utility model is achieved in that adopting the measuring fixed amount pump to inject pH value to the reactor that the aluminum phosphate medicament is housed is the acid solution of 4-7, by with the critical flow Venturi tube being the PH of the constant volume dilution distributing system of core with generation
3Mixing also with gasometries such as air or nitrogen, constant volume is delivered to reserve storage.
The utility model adopts constant volume dilution transmission ﹠ distribution technology can fumigate the generation of gas, preparation, conveying and stifling operation easy, safe, stable, reliably in the reserve storage that possesses environment recirculation fumigation system; Substitute greenhouse gases-CO with air or nitrogen
2, compliance with environmental protection requirements; Unique by product is recycled fully through deep processing, has overcome steel cylinder gas technology intermediate transportation link simultaneously and has leaked the environmental pollution that causes, and does not have three-waste pollution; Running cost is low, implements to be easy to realize.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 takes place and transportation and distrubution apparatus flowage structure figure according to the efficient fumigant that the utility model proposes.
Fig. 2 is that the utility model adopts prior art online detection that constitutes and the fundamental diagram of implementing control device.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device comprises PH
3Metering generator 1, constant volume dilution dispenser 2, online detection and real-time controller 3.Wherein at PH
3Metering generator 1 has 4, one of measuring pumps to bring the reactor 5 of material interface, blanking interface and agitating device into.At constant volume dilution dispenser 27, one exhaust tubes 8 of 6, one Venturi tubes of a tool filter blender are arranged.Comprise that in online detection and real-time controller 3 one is enclosed within the central controlled processing unit 9 that detects with real-time control.
After opening aspiration pump 8, the constant volume effect of Venturi tube 7 makes by PH
3The PH that metering generation systems 1 generates
3Mix with process filter blender 6 filtered airs or nitrogen metering, under the effect of aspiration pump 8, carry the pipe-line system in the big army banner reserve storage.The whole operation process can be carried out online detection and be controlled in real time or manual adjustments by central controlled processing unit 9.Though back one mode is simple, also in full force and effect.
