Description

High-pressure spraying greenhouse cooling system

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the environmental protection equipment, especially, relate to a high pressure spraying big-arch shelter cooling system.

[ background of the invention ]

Spraying equipment is common in the environment that net room big-arch shelter, plastic greenhouse, glass warmhouse booth etc. are used for planting crops, and the water smoke that spraying equipment sprayed can have the effect of cooling down and control humidity, avoids crops too dry, reduces operation personnel body surface temperature, and also has certain effect to inhibiting the worm's ovum hatching, hindering the pest flight.

Referring to fig. 4, which is a conventional spraying apparatus 100 on the market, a pump 300 is used to deliver water from a water source 200 to a spraying pipe 400, and sprayers 500 are assembled in the spraying pipe 400, and when a plurality of sprayers 500 are activated, the water in the spraying pipe 400 is sprayed from the sprayers 500.

However, the above spraying apparatus has many problems, the more the sprayer 500 located at the end of the spraying pipeline is, the more the water outlet pressure is attenuated, and the lower the water outlet pressure is attenuated, the worse the atomization effect is, the larger the sprayed water mist particles are, the larger the water mist particles are, the more the water mist particles are not easy to be uniformly diffused, and further the humidity of the indoor part is uneven, and the water mist particles falling on the surface of the crops are not easy to evaporate. Although the water mist stays on the surface of the crops properly to help avoid drying, the water mist can cause bacterial growth of the crops after staying for a long time, and in order to improve the problem that the water pressure of the sprayer 500 at the tail end of the spraying pipeline 400 is too low, a pressure regulating valve 600 is established at the front end of the spraying pipeline, or the horsepower of the pump 300 is increased to increase the water pressure and the flow speed of the water flowing into the spraying pipeline 400, however, the method solves the problem that the water pressure of the sprayer 500 at the tail end of the spraying pipeline 400 is too low, but the flow speed of the water flowing into the spraying pipeline 400 is increased along with the increase of the heat energy generated by the friction between the water flow and the pipe wall, so that the temperature reduction function of the sprayed water mist is reduced, therefore, the technical means is not good, in addition, when the water is not sprayed by the sprayer, the water mist is remained in the spraying pipeline and is heated along with the sun, when the water mist is sprayed by the, so that the cooling effect is greatly reduced.

Therefore, there is a need to provide a high-pressure mist cooling system for a greenhouse to solve the above problems.

[ detailed description ] embodiments

Example (b):

referring to fig. 1 to 3, the present embodiment is a high-pressure spray greenhouse cooling system 1, which includes: the device comprises a water tank 2, a pump 3 communicated with the water tank 2 through a water outlet waterway 8, a spraying pipeline 6 with one end communicated with the output end of the pump 3 and the other end communicated with the water tank 2 through a water return waterway 9, and a plurality of sprayers 7 arranged on the spraying pipeline 6; a pressure regulating valve 5 is arranged on the water return waterway 9; the output end of the pump 3 is communicated with the water tank 2 through another pressure relief water path 10 to form a loop, and a pressure relief set 4 is arranged on the pressure relief water path 10.

Referring to fig. 2, the pressure relief set 4 includes a pressure relief valve 41 and a pressure relief solenoid valve 42 connected in parallel with the pressure relief valve 41.

When the system is in operation, the pump 3 outputs water from the water tank 2 and divides the water into two paths, one path flows to the pressure relief water path 10, when the water flows through the pressure relief valve 41, the pressure of the water is set according to the pressure of the pressure relief valve 41, part of the water flows back to the water tank 2 through the pressure relief valve 41, the other path of the water continuously flows to the spray pipeline 6, the water pressure flowing from the output end of the pump 3 to the spray pipeline 6 is controlled, the sprayer 7 controls the water in the spray pipeline 6 to be sprayed out and not sprayed out through the sprayer 7, the water not sprayed out from the sprayer 7 flows to the water tank 2 through the return water path 9 through the pressure regulating valve 5, the pressure regulating valve 5 controls the water pressure flowing from the spray pipeline 6 to the return water path 9, when the water amount in the water tank 2 is reduced due to the spraying of the water mist sprayed out by the sprayer 7, the water source 11 supplements water according to the setting of an internal switch, avoid the residual pressure of spraying pipeline 6 to make plural number atomizer 7 infiltration water drip, cause the water resource of wasting and influence the operation environment to be convenient for maintain and change plural number atomizer 7.

In general, when the mist is sprayed from the sprayer 7, the pressure of the discharged water is maintained at 75kgf/cm²(kilogram force/square centimeter) to 100kgf/cm²If it is less than 70kgf/cm²The atomization effect is greatly reduced, and the water mist particles are too large, and if the outlet water pressure exceeds 105kgf/cm, the outlet water pressure is too high²The high-pressure friction of the water with the head of the atomizer 7 causes an excessive temperature rise of the sprayed mist. The pressure release valve 41 is provided to control the water pressure flowing from the water outlet channel 8 to the spraying pipeline 6, so as to avoid the over-high water outlet pressure when the sprayer 7 near one end of the pressure release valve 41 sprays water mist, and also avoid the tube explosion caused by the over-high pressure in the spraying pipeline 6. The lower the water outlet pressure of the sprayers 7 at the rear section of the spraying pipeline 6 in each sprayer 7, and the setting of the pressure regulating valve 5 can regulate the water pressure of water flowing from the spraying pipeline 6 to the water return waterway 9 so as to increase the water outlet pressure of the sprayers 7 at the rear section of the spraying pipeline 6. In the embodiment, the pressure release valve 41 is matched with the pressure regulating valve 5 to ensure that the outlet water pressure of the sprayer 7 is maintained at 75kgf/cm²～100kgf/cm²。

Compared with the prior art spraying device 100 shown in FIG. 4, the water outlet pressure of the sprayer 500 at the rear section of the spraying pipeline 400 is lower than 70kgf/cm²However, the increase of the water outlet pressure at the water outlet end causes the problems of the atomizer 500 at the front section of the spraying pipeline 400, such as the water outlet pressure being too high, the water flow excessively rubbing the inner wall of the pipe, and the like.

In addition, in the present embodiment, the water not sprayed from the sprayer 7 is prevented from continuously staying in the spray pipeline 5 by the loop formed by the water outlet pipeline 8, the spray pipeline 6 and the water return pipeline 9.

Referring to fig. 3, the present embodiment further includes a filter 12, the filter 12 is disposed between the water tank 2 and the water source 11, and the filter 12 is disposed to filter water flowing from the water source 11 to the water tank 2, so as to prevent debris such as stones, dust, etc. from flowing into the water tank 2, which may cause damage to equipment due to stones impacting the pump 3 and pipes, and may cause problems such as dust blocking the sprayer 7, blocking the pressure release unit 4, and blocking the pressure regulating valve 5 during system operation.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
