Embodiment Construction

[0008] When the equipment is working, the power supply of the negative high voltage module (1) is connected, a negative high voltage is added to the negative plate (6) of the gas ionization channel, and the positive plate (9) of the gas ionization channel is grounded. The gas in the controlled atmosphere storage is introduced into the ethylene removal chamber formed by the negative electrode plate (6) of the gas ionization channel and the positive electrode plate (9) of the gas ionization channel through the intake fan (7), and the gas chamber generates a large amount of ozone to oxidize ethylene After decomposing, the gas after removing ethylene returns to the controlled-atmosphere storage through the outlet channel (11).

[0009] In this device, the output voltage and current of the negative high-voltage power supply module (1) are adjustable; the distance between the gas ionization channel negative plate (6) and the gas ionization channel positive plate (9) is adjustable, an...

Abstract

An ethene removing apparatus for the gas conditioning fruit and vegetable storage features that two plate electrodes are respectively installed to top and bottom of the ethene removing room, the lower electrode is connected to ground, a negative DC voltage is applied across said two electrodes and the high-voltage discharge can release ozone to decompose said ethene by oxidizing it.

Description

Technical field [0001] The invention relates to a device for removing ethylene, which can be used for removing ethylene in controlled-atmosphere storage of fruits and vegetables. Background technique [0002] Ethylene is a plant hormone produced by the metabolism of fruits and vegetables that can promote the ripening and aging of fruits and vegetables. Therefore, the controlled atmosphere storage must be equipped with ethylene removal device. There are many ways to remove ethylene, such as washing method, dilution method, adsorption method, chemical method and so on. At present, the main methods used in production are oxidation method and heating catalytic method. The oxidation method is to soak the porous material with potassium permanganate aqueous solution, and then put the carrier into the warehouse, packing box or closed circuit system, and use the strong oxidation of potassium permanganate to remove ethylene. The removal efficiency of this method is low, and the car...
