Description

Fumigation Apparatus

The present invention relates to a fumigant vaporizer, and more particularly to a fumigant vaporizer capable of being used in a safer and more efficient manner than a conventional one by vaporizing fumigant that can be widely used for agriculture or quarantine because it has an insecticide, The present invention relates to a fumigant vaporizer capable of continuously producing and supplying nitrogen by connecting a nitrogen generator to a fumigant vaporizer, thereby providing economical efficiency.

A fumigant is a generic term for a volatile drug, or chemical, used to kill insects or pathogens.

Generally, fumigants are widely used for agricultural or quarantine purposes because they have insecticidal, bactericidal and herbicidal effects.

It is known that these fumigants include hydrogen cyanide, calcium cyanide, carbon dioxide, sulfur dioxide, chloropicrin, carbon tetrachloride, ethylene dichloride, ethylene bromide, p-dichlorobenzene, It is used for insecticide and sterilization of soil.

Of course, if fumigants remain in the soil in large quantities, the soil will be contaminated. If the fumigants and ships are sterilized and washed with water, they will be contained in the water and pollute the water quality.

When the fumigant is used, it is common to heat the liquid fumigant to produce a fumigant, and then supply the fumigant to a fumigant such as a warehouse, ship, fruit tree, soil or the like.

On the other hand, it is known that the current technology of using fumigants is very common to use methyl bromide.

However, in the case of methyl bromide, which is known to be an ozone-depleting substance, most of the fumigants are administered with fumigating agents through a simple vaporizer in order to alleviate the weakness in the low-temperature treatment or the fumigant, There is a problem that a safety accident of workers is caused due to the remaining amount of unburned fumed vaporized material.

On the other hand, in the case of the fumigant (EF + CO2 mixed high-pressure gas) developed as a substitute for methyl bromide, the vaporizer is used due to the freezing of the gas tube in use, but the mixed gas is charged at high pressure, However, since the gas cylinder itself is heavy, there is a problem that a safety accident of a fumigant may occur. Therefore, it is necessary to develop a technology of a fumigant vaporizer considering these considerations.

1, the nitrogen supply unit 200 provided in the present invention is provided outside the casing 110 to supply nitrogen into the casing 110 of the fumigational vaporization unit 100, Has the feature that it can continuously produce, store and supply nitrogen.

That is, the nitrogen supply unit 200 includes a nitrogen generator for extracting and discharging nitrogen from the air. The nitrogen supply unit 200 can stop operation of the compressor 210 according to the amount of nitrogen used in the fumigation unit 100 The oxygen concentration of the oxygen supplied to the first nitrogen separation tank 220 and the second nitrogen separation tank 230 is maintained at 100 ppm by the timer automatic control unit 280 so that the first nitrogen separation tank 220 and the second The supply time of the compressed air supplied to the nitrogen separation tank 230 is variably controlled.

Accordingly, the automatic timer control unit 280 controls the nitrogen generator to stop the operation of the compressor 210 according to the compressed air supply replacement time.

The nitrogen supply unit 200 according to the present embodiment includes a compressor 210, a first nitrogen separation tank 220, a second nitrogen separation tank 230, an adsorbent 240, a nitrogen storage tank 250 A gas exhaust pipe 260, a control unit 270, and a timer automatic control unit 280.

First, the compressor 210 is provided to supply compressed air to the nitrogen generator through the air sucked into the atmosphere.

A supply pipe for supplying air compressed by the compressor 210 to the nitrogen generator is connected to the first nitrogen separation tank 220 and the second nitrogen separation tank 230.

The first nitrogen separation tank 220 receives compressed air from the compressor 210 to separate nitrogen.

The second nitrogen separation tank 230 receives compressed air from the compressor 210 to separate nitrogen.

At this time, an adsorbent (240) is disposed in the first nitrogen separation tank (220) and the second nitrogen separation tank (230) to adsorb oxygen contained in the inflow air.

The adsorbent 240 adsorbs oxygen to exhaust only nitrogen.

Nitrogen generated from the first nitrogen separation tank 220 and the second nitrogen separation tank 230 is supplied to the nitrogen storage tank 250.

The nitrogen storage tank 250 moves nitrogen from the first nitrogen separation tank 220 to the second nitrogen separation tank 230 and receives the nitrogen from the second nitrogen separation tank 230.

If the adsorbent 240 is also disposed in the nitrogen storage tank 250, only the high purity nitrogen can be supplied by adsorbing the remaining oxygen.

The nitrogen is connected to the nitrogen storage tank 250 and the casing 110 of the fumigation unit 100 to supply nitrogen into the casing 110.

The gas supply pipe 260 is connected to the nitrogen storage tank 250 and the casing 110 of the fumigation unit 100. The gas supply pipe 260 is connected to the nitrogen storage tank 250 To be supplied into the casing 110 of the fumigating unit 100.

The nitrogen storage tank 250 and the nitrogen generator may be controlled by the controller 270.

The controller 27 controls the nitrogen storage tank 250 and the nitrogen generator so that the oxygen concentration supplied to the first nitrogen separation tank 220 and the second nitrogen separation tank 230 is maintained at 100 ppm.

At this time, the concentration of oxygen can be changed by the controller 270 and the oxygen concentration can be kept constant.

In addition, the controller 270 can check the normal operation of the compressor 210 and adjust the nitrogen amount and the oxygen concentration.

The control unit 270 may include a timer automatic adjustment unit 272.

The timer automatic regulating unit 272 controls the first nitrogen separating tank 220 and the second nitrogen separating tank 230 so that the oxygen concentration supplied to the inside of the first nitrogen separating tank 220 and the second nitrogen separating tank 230 is kept constant at 100 ppm, And the supply time of the compressor 210 for supplying the compressed air to the second nitrogen separation tank 230 alternately.

That is, if the timer automatic regulating unit 272 sets the O ₂ PPM (concentration) to 100 and increases the replacement time of the first nitrogen distribution tank 220 and the second nitrogen separation tank 230, Compressed air is supplied in a small amount.

The timer automatic regulating unit 272 can variably operate the nitrogen production amount of the nitrogen generator in accordance with the nitrogen use amount fluctuation in the fumigation unit 100. [

For example, when comparing a conventional nitrogen generator with a nitrogen generator used in the fumigator of this invention, a typical nitrogen generator requires 10 liters of compressed air in a compressor to produce 10 liters of nitrogen, but even when producing 1 liter of nitrogen, 10 liters of air is required.

However, the nitrogen generator of the present invention supplies 10 L of compressed air from the compressor 210 when producing 10 L of nitrogen.

Alternatively, 1 liter of compressed air is supplied from the compressor 210 when producing 1 liter of nitrogen in the nitrogen generator.

A typical nitrogen generator Nitrogen generator applied to the present invention Compressed air
l / hr nitrogen
l / hr O ₂ PPM Compressed air
l / hr nitrogen
l / hr O ₂ PPM 64,212 12,000 100 64,212 12,000 100 63,182 11,000 80 53,133 11,000 100 62,358 10,000 50 47,272 10,000 100 60,576 9,000 30 42,343` 9,000 100

Here, the consumer does not require a low O ₂ concentration.

As shown in Table 1 above, when the O ₂ PPM is set to 100, the compressed air of the present invention produces about the same amount of nitrogen as that of the conventional nitrogen generator, which is 30% less than that of the conventional nitrogen generator.

Specifically, a conventional nitrogen generator is an O ₂ PPM PPM falls state O ₂ is not set to continue to operate the compressor to increase the nitrogen production.

However, when the nitrogen generator of the present invention is set to O ₂ PPM of 100, the compressed air pressure is lowered even if the nitrogen production amount of the normal nitrogen generator is the same. Nitrogen can be produced at the same pressure as a conventional nitrogen generator.

Therefore, the compressor 210 does not need to be continuously operated.

At this time, when the O ₂ PPM falls below 100, the time for supplying the compressed air alternately from the compressor 210 to the first nitrogen separation tank 220 and the second nitrogen separation tank 230 is increased.

That is, the timer automatic regulator 272 controls the first nitrogen separation tank 220 and the second nitrogen separation tank 250 so as to variably supply the amount of compressed air supplied to produce nitrogen according to the nitrogen usage amount of the fumigation unit 100, (230).

The timer automatic regulator 272 adjusts the supply replacement time of the compressor 210 for alternately supplying compressed air to the first nitrogen separation tank 220 and the second nitrogen separation tank 230 by varying the supply amount of compressed air .

In this way, the timer automatic control unit 272 maintains the O ₂ PPM of the control unit 270 to 100 and operating oxygen pressure drops to less than 100, while the working operation of the compressor 210, the replacement time units O ₂ PPM is maintained at 100. When the pressure is reached, the power is automatically turned off to stop the operation of the compressor (210).

In addition, the automatic timer control unit 272 stops the operation of the compressor 210 according to the compressed air supply replacement time, and does not continuously operate the compressor 210, thereby reducing power consumption.

Thus, the present invention can increase the productivity by continuously producing nitrogen and supplying it to the fumigating unit 100.

Meanwhile, in the embodiment of the present invention, it is preferable that a vessel-type hot air fan 150 is provided for generating nitrogen gas and heating the nitrogen gas when it is supplied to a lower region in the casing 110 and is injected.

The bezel-type heat exchanger 150 is installed on the path of the gas supply tube 260.

The second heater 152 may be embedded in the bezel-type heat exchanger 150 to allow the nitrogen gas to flow into the bezel-type heat exchanger 150, Will be described in detail in a third embodiment to be described later. In particular, the nitrogen gas introduced into the vesel-type hot air fan 150 is preferably introduced into the mist by an injection nozzle (not shown) in order to improve the performance of heat exchange between the second heater and the nitrogen gas.

The present invention can solve the problem of reducing the effect due to the low temperature of the nitrogen gas by being supplied via the above-mentioned barcel-type hot air fan.

In this way, nitrogen gas, which is heated by the vessel-type hot air fan 150 and supplied to the inside of the casing 110, is injected. To this end, the tip end of the gas supply tube 260 supplied to the inside of the casing 110 enters into the casing Is extended.

Therefore, in the present invention, the nitrogen gas heated and supplied by the bezel-type air blower 150 is injected into the inner space of the casing 110, and is vaporized by the first heater 130 to move the fumigant-vaporizing material upward .

In order to inject nitrogen gas into the casing 110, the end portion of the gas supply tube 260 located inside the casing 110 so as to be adjacent to the lower portion of the fumace- And it is preferable that a plurality of injection holes 172 are formed inside the ring shape.

The gas supply pipe 260 may be made of stainless steel to prevent corrosion. At least a portion of the side wall of the gas supply pipe 260 is provided with a plurality of spray holes 172 Is formed.

At this time, the total area of the spray holes 172 is smaller than the area of the gas supply pipe 260, and each size may have a diameter within a range of 10-30 mm. Of course, its value can not be limited to the scope of the invention.

As an example of such a spray hole 172, it can be processed into the structure of the shaft hole 172a, the orifice extension hole 172b, and the diameter hole 172c as shown in Fig.

The shaft hole 172a is a portion where the diameter gradually decreases along the direction in which the nitrogen gas is injected. The shaft hole 172a prevents a vortex that may be generated when the fumigant is initially introduced into the injection hole 172, thereby allowing the fumigant to flow uniformly and stably.

The orifice extension hole 172b communicates with the shaft hole 172a and is formed by extending the smallest diameter portion of the shaft hole 172a. By adjusting the shape of the orifice extension hole 172b, the flow rate of the fumigant can be adjusted.

The diameter hole 172c is communicated with the orifice extension hole 172b and is a portion where the diameter is gradually increased along the direction in which the nitrogen gas is injected. The aperture 172c serves to uniformly and stably spread and fuse the fumigant.

Even if a structure in which the injection hole 172 is formed by a structure of the shaft hole 172a, the orifice extension hole 172b, and the diameter hole 172c instead of the simple hole is applied, it has insecticidal, sterilizing and herbicidal effects Fumigation which can be widely used for agricultural or quarantine purposes can be used in a safer and more efficient manner than before.

In addition, the costs associated with the use of fumigants can be reduced, and the device can be simplified.

Meanwhile, the first heater 130, which functions to generate fumigant by heating the fumigant supplied to be dropped in the lower region of the casing 110, may be provided to accelerate the generation of the fumigant vaporization material.

In an embodiment of the present invention, the first heater 130 may be controlled by the controller 140, wherein the first heater 130 may be an electric heater or a thermal power heater.

As a result, the fumigant according to the present embodiment has insecticidal, sterilizing and herbicidal effects, so that a fumigant that can be widely used for agricultural or quarantine purposes is supplied into the casing, and then heated to generate a fumigant vaporizing material. And can be safely and efficiently used as a fumigant.

That is, the present invention not only makes it possible to use fumigants in a safer and more efficient manner than before, but also can reduce the costs associated with the use of fumigants and simplify the apparatus.

In addition, the controller 140 controls the operation of the first heater 130. The controller that performs this role may be configured to include a central processing unit (CPU) 142, a memory (MEMORY) 144, and a support circuit (SUPPORT CIRCUIT) 146 as shown in FIG.

The central processing unit 142 may be one of various computer processors that are industrially applicable to control the operation of the first heater 130 in this embodiment.

The memory 144 is connected to the central processing unit 142. The memory 144 may be a computer-readable recording medium and may be located locally or remotely and may be any of various types of storage devices, including, for example, random access memory (RAM), ROM, floppy disk, hard disk, At least one or more memories.

The support circuitry 146 is coupled with the central processing unit 142 to support the typical operation of the processor.

Such a support circuit 146 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

In this embodiment, the controller 140 controls the operation of the first heater 130. At this time, a series of processes or the like in which the controller 140 controls the operation of the first heater 130 may be stored in the memory 144. [ Typically, software routines may be stored in memory 144. [ The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being executed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

According to the fumigant vaporizer of the first embodiment having such a structure and action, since fumigation, sterilization and herbicidal effects are achieved, it is possible to use fumigants widely used for agricultural or quarantine purposes in a safer and more efficient manner than before.

Further, according to the fumigant vaporizer of the present embodiment, it is possible to reduce the costs associated with the use of the fumigant and simplify the apparatus.

I will add to the effect of this design. In terms of fumigant use, the design is a technology that can facilitate the use of relief of methyl bromide, an ozone depleting substance in global use reduction, and the economic use of expensive substitute materials.

Fumigation of fumigants such as imported fruits and vegetables In the case of low fumigation, the effect of controlling the permeability of the gas itself may be inferior. However, the present invention has a function of mixing the nitrogen gas, It becomes possible to maximize it.

The effect of this design is summarized as follows.

First, the function of the conventional simple vaporizer used in the field can be mixed with, for example, nitrogen gas and fumigant, so that the efficiency of the fumigant vaporization material can be increased and used safely. Particularly, the nitrogen gas is supplied in a spray form through the injection nozzle, so that the function can be maximized.

Secondly, the vaporization pressure can be increased due to the above-mentioned matters, and ultimately, the penetration ability of gas can be increased, thereby maximizing the effect of fumigation such as banana, orange, and pineapple.

Third, since it is structurally stable and convenient to handle, it is possible to minimize the amount of fumigation inhaled by the operator, thereby enabling safe operation.

Moreover, the present invention can be used while generating nitrogen gas, so that the capacity is not limited, and the productivity can be improved.
