Description

[0001] The present invention relates to a micro fog formation apparatus and a fog formation method,

The present invention relates to a micro-fog forming apparatus and a fog forming method, and more specifically, to provide finer fog formation than a generally used low-pressure fog, thereby maximizing fog efficiency while minimizing the use of water and compressed air In addition, it is intended to provide a microfog forming apparatus and a forming method that can be applied variously to tube housing, humidification, and temperature control in industrial facilities as well as facilities for cultivating or housing such as vinyl houses.

Fogs that can make fine droplets such as fogs are installed in plastic houses and farmhouses where vegetables and horticultural crops are cultivated for the purpose of spraying a chemical solution and controlling humidity and temperature.

Generally used plastic fog is a hog connection pipe which is formed by one side, both sides or four directions and the hosel coupling pipe in which the insertion pipe and the hose are inserted in the upper and lower sides, A nozzle fixing hole formed at the lower end of the fixing protrusion to be engaged with the fixing jaw of the fixture and having a handle protruded from both sides of the nozzle protrusion, a nozzle inserted into the nozzle insertion hole penetrating through the nozzle fixing hole to form a stopping jaw, And a nipple that is formed on the upper side of the fixing part and has a flow path for supplying water to the nozzle side in the insertion direction and screwed to the nozzle fixing hole.

In the nozzle, a nipple guiding jaw is formed on the lower side of a body provided with an engagement protrusion protruding from a protruding protrusion formed on a nozzle insertion hole, and a conical vortex And a flow path for guiding water into the vortex space from the outside of the body is formed at the lower end of the vortex holes. The insertion tube and the nipple of the fixture are separated from each other in the assembled state, . In the case of the conventional plastic fog, there is a problem that the nozzle can not be pressed firmly when the screw is worn in the process of disassembling and assembling the nipple for cleaning the nozzle. In the close contact structure between the nozzle fixture and the nozzle, Since the engaging jaw and the rotary shaft on the engaging step formed on the body of the nozzle are in a point contact configuration, there are many problems such that the function of the nozzle is deteriorated when a small scratch is generated in the rotary shaft.

 In order to solve the above problems, the inventor of the present invention has developed a plastic fog of Korean Registered Utility Model No. (Y1) 20-0419612 (2006.06.21.), And its configuration is such that the contact between the nozzle fixture and the nozzle is in surface contact And the lower end of the nipple is brought into contact with the insertion tube formed on the upper side of the fixed body so that the nozzle is always fixed under the same condition and the flow path of the same height And a plurality of flow paths are formed so that the water supply and fog efficiency can be increased even under a low pressure.

Meanwhile, various techniques for generating fog have been proposed. For example, there is a fog nozzle of Korean Patent Laid-Open Publication No. 10-2010-0035839 (Apr. 07, 2010). In this case, A nozzle body having an engaging hole formed on an inner circumferential surface of the other end; A pressure pin having a head formed with a guide groove at one end thereof and inserted into and coupled with an inner circumferential surface of the other end of the body; The other end of the elastic body is inserted into the inner circumferential surface of one end of the elastic body and the inlet hole through which the fluid flows into the outer circumferential surface of the other end is cut and the outer circumferential surface of one end is inserted into the coupling hole of the nozzle body, .

Another example is an air fog generator of the Registered Patent Publication (B1) 10-1232340 (Mar. 23, 2013), in which a first cylindrical housing having a water supply port adapted to be screwed together, A liquid pressure regulating unit provided inside the housing to regulate the pressure of the water to be supplied to the nozzle regulating unit so as to adjust the pressure of the water to be supplied; And a gas-liquid mixing unit for mixing fine air droplets with the air introduced through the nozzle holes, wherein the discharge pressure of the liquid pressure adjusting unit can provide a pressure higher than the air pressure of the gas-liquid mixing unit.

Another example is a superfine atomizing spray nozzle of Korean Patent Laid-Open Publication No. 10-2006-0128289 (Dec. 14, 2006). In this case, a partition wall is provided on the outer circumferential side of the liquid passage, And the gas passage communicating with the injection port (injection port) has an outer shape on the injection port side of the partition wall in a polygonal shape, a long circular shape, or an elliptical shape in cross section, In this circular shape, the outer surface of the circular cross section of the circular cross section is abutted at a plurality of locations on the outer surface of the partition wall to separate the gas passageway on the spray side into a plurality of gas passages in the peripheral direction, or the outer surface of the partition wall The outer peripheral surface on the side of the injection port of the gas passage is formed into a polygonal section, a long circular section or an elliptical section, and the outer circumferential surface of the partition wall faces the surface The gas passage on the side of the spray is separated into a plurality of gas passages in the circumferential direction and the gas injected from the ejection openings of the separated plurality of gas passages is mixed with the outer periphery of the liquid injected from the liquid passages So that the spray can be generated.

However, in the above-described configurations, since the water (fluid) is pulverized only once to form the fog, there is a limit in providing micro fog. In the case of the technologies using compressed air, most of the technologies are injector type, Are difficult to use.

On the other hand, existing fog products can make very small micro fogs by constructing a vortex structure in a continuous water supply structure as in the prior art and by hanging it at high pressure, but this high pressure fog has a hole size of 0.1 to 0.3 mm, so that it was clogged by this substance floating in water or dissolved calcium ions or iron ions and was almost impossible to clean.

In addition, the low pressure micro fog uses an air flow, and there is a method in which water is continuously supplied to the venturi space to break the particles finely. However, there is a disadvantage that a somewhat large amount of air must be used. Thus, there is a disadvantage that the capacity of the compresor must be increased.

In the case of a fog pulverizing water by microwaves due to the flow rate of air coming out at a high pressure with the flow direction of the water being equal to the direction of the air, the compressed air is consumed so that not only the capacity of the compressor is high, There is a problem in that it is necessary to take out the water in the pipe itself and it is structurally complicated to insulate the waterproof structure itself, so that it becomes expensive.

Accordingly, the present inventor has researched and developed the present invention to provide a microfog which can not be provided in the conventional low pressure fog described above. In the present invention, water particles such as a primary mist are formed by using a low pressure fog, The fog-like fog-like particles are re-pulverized by the venturi principle, so that the micro-state fog can be formed, thereby maximizing the fog efficiency while minimizing the amount of water and compressed air, And it can be used for spraying fine water particles such as fog by applying variously to tube housing, humidification, and temperature control in industrial facilities as well as facilities such as vinyl house for cultivation or housing The present invention provides a micro fog formation apparatus and a fog formation method using the same.

The micro fog forming apparatus and the fog forming method provided by the present invention can provide a microfog with high efficiency at a low cost.

That is, according to the present invention, fine water particles such as fog are produced by pulverizing fine water particles provided in a low-pressure fog again in a venturi nozzle, and it is possible to maximize fog efficiency while minimizing water consumption .

 When the present invention is used for the cultivation of a facility such as a vinyl house, the chemical solution can be sprayed evenly throughout the plant because the chemical solution is sprayed in the air when the chemical solution is sprayed.

Also, since the fog is provided in the micro state, it is easy to humidify in agricultural or industrial use, and when installed on the ventilation side such as industrial facility in summer, it is very advantageous to reduce the room temperature by improving the atmospheric flow.

In addition, because the nano material is contained in the nozzle body, the fluid guide member or the venturi nozzle of the low pressure fog, it is possible to prevent the bacteria from living in the residual water. Therefore, when the present invention is used for humidification, can do.
