Description

In agriculture, installations for gas disinsection of grain dami, equipped with diffuser fans, which serve to form the gas-air mixture supplied to the tubular perforated tips, are known.

The proposed installation of this type differs from the known ones in that the diffuser chamber in it, for better mixing and air distribution, is equipped with a series of nozzles, along which g is introduced into the chamber under pressure.

Before sucking in, the calorife is applied to it by the fan of the installation fan | for heating the air entering the pipe, which is used in the formation of the gas-air mixture.

FIG. 1 shows a general view of the degassing apparatus in the plan, and FIG. 2 - a general view of the installation for the degassing of grain.

The operation of the installation is as follows: the liquid fumigant from the tank is supplied by the compressor 7 through copper tubes to the special nozzles 2, which by means of compressed air sprays the liquid into the misty glass. one.

Stand and feed it in the form of a short torch into the evaporation-mixing chamber 3. The air continuously blown by the fan 4 passes through this chamber and is saturated with suspended fine fumigant particles. When spraying, the fumigant particles get a significant speed and mix with the main air flow.

Due to the heating of the air by the heater 5, the suspended fumigant particles rapidly evaporate and the resulting air-gas mixture is injected through the pipeline and through the tips into the intergranular space.

The required concentration of fumigant in the air-gas mixture is established by adjusting its flow through the nozzles 2.

When the grain is carbonized under storage conditions, air is sucked from the surrounding atmosphere by the fan 4 and is injected into the evaporation-mixing chamber 5, where an air-gas mixture is formed, and then the mixture is directed to the discharge pipeline 6 to the distribution pipeline 7 and

the latter to the perforated tips 8, each of which is a metal pipe with a conical tip welded to the bottom.

After about. 16 hours after aeration, the grain is degassed according to the TOjS scheme, only the evaporator does not start up and the injected air is supplied to the intergranular space clean from the atmosphere.

Subject invention

I. Mobile installation for gas disinsection of grain using a solution tank and a fan with a diffuser serving; to form a gas-air mixture | and supply it to tubular perforated tips, Q: It is because in order to spray better and to mix it with air, the diffuser chamber is equipped with a number of nozzles, through which liquid ejects the compressor through

2. Application at installation of the p. P. 1 of the heater, located in front of the suction pipe of the fan and used for heating vfduh, going to the formation of gas-air mixture.
