Embodiment 1

[0027] The embodiment of the present invention provides a sliding arc discharge nitrogen fixation generating device for foliage fertilization in facility agriculture, such as figure 1 shown, including:

[0028] a discharge unit 100 for forming a sliding arc to generate plasma to excite air to generate NOx active radicals; and,

[0029] The nitrogen fixation unit 200 is used to mix the air containing NOx active groups from the discharge unit with water to form liquid nitrogen fertilizer.

[0030] Such as figure 1 As shown, the discharge unit 100 includes a reaction cover 101, an insulating spacer 102, an air compressor 103, a nozzle 104, a high voltage power supply 105 and at least two knife-shaped bifurcated electrodes 106, wherein:

[0031] The insulating isolation plate 102 is fixed inside the reaction cover 101, and is used to divide the reaction cover 101 into a first cavity and a second cavity;

[0032] The air compressor 103 is arranged in the first cavity, and is use...

Embodiment 2

[0049] The embodiment of the present invention also provides a sliding arc discharge nitrogen fixation generating device for foliar fertilization in facility agriculture. The difference between this device and the device in Embodiment 1 is that it also includes a controller (not shown in the figure) , the controller is connected with the high-voltage power supply 105, and is used to generate AC high-voltage electricity of different voltage levels when receiving control instructions, and uses the sliding arc generated by the knife-shaped bifurcated electrode 106 to generate different degrees of discharge, thereby producing the desired content Active groups such as NOx can further obtain liquid nitrogen fertilizer with precise nitrogen content. Other parts of the device provided in this embodiment are the same as those of the device in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to a gliding arc discharge and nitrogen fixation generation device for foliage dressing of facility agriculture. The device comprises a discharge unit for forming a gliding arc to generate plasmas to excite air to generate NOx active groups and a nitrogen fixation unit for mixing the plasmas from the discharge unit with water to form liquid nitrogen fertilizer. According to the gliding arc discharge and nitrogen fixation generation device, nutritional supplementation can be performed on crops, and the effective absorptivity of the crops to the fertilizer can be improved; sterilization can be performed while the dressing cost is reduced, and therefore the bacterium infecting probability of the crops is decreased; active substances in the liquid nitrogen fertilizer are easy to decompose, and therefore environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a sliding arc discharge nitrogen fixation generating device used for foliage fertilization in facility agriculture. Background technique [0002] In the production of facility agriculture crops, farmers supplement the elements needed by crops by applying chemical fertilizers. At present, farmers use nitrogen fertilizers for liquid fertilization. However, after fertilization, the soil will harden to a certain extent, and the crops will not be used for growth; and the cost of liquid fertilization of nitrogen fertilizer after purchase is relatively high; and when liquid fertilization is used, it is easy to cause waste of resources; the mobility of nitrogen is large and it is easy to flow away with water, resulting in nitrogen fertilizer. The utilization rate is reduced, and most of the nitrogen entering the environment will cause environmental pollution. Contents o...
