Abstract
An ethylene removing device for a fruit and vegetable controlled atmosphere storage. It fixes a plate electrode on the upper and lower sides of the ethylene removing room, the upper plate electrode is connected with DC negative high voltage, the lower plate electrode is connected with ground. After the power supply is switched on, ozone is generated by high-voltage discharge in the ethylene removal chamber to oxidize and decompose ethylene.
Description
Affiliated technical field
The present invention relates to a kind of equipment that removes ethene, can be used for fruit and vegetable air conditioned storage storehouse and remove ethene.
Background technology
Ethene is the plant hormone that can promote the ripe aging of fruits and vegetables that a kind of fruits and vegetables metabolism produces.Therefore, air-conditioned cold store must be installed the ethylene removal device.The method that removes ethene has multiple, as WATER-WASHING METHOD, dilution method, absorption method, chemical method etc.Produced at present and gone up mainly containing oxidizing process and heating catalysis method of adopting.Oxidizing process is to soak porous material with potassium permanganate solution, then this carrier is put into storehouse, packing case or closed circuit circulatory system, utilizes the strong oxidizing property of potassium permanganate that ethene is removed.This method removal efficiency is low, also will often change carrier, and potassium permanganate has very strong corrosiveness, is not easy to modern air-conditioned cold store operation.Along with the development of air conditioning technology, develop a kind of novel efficient ethylene removal device in recent years again, it is under the condition of catalysis of heating, and ethene is resolved into water and carbon dioxide.By closed circuit circulatory system the gas that removes behind the ethene is sent in the air-conditioned cold store, and so forth, finished the process that removes ethene.Compare with oxidizing process, this method can turn round continuously automatically, the removal efficiency height.Also multiple harmful substances and aroma gases that fruits and vegetables discharge can be removed simultaneously, be particularly suitable for modern air-conditioned cold store and use.This equipment is representative with the product of Italian FRUIT CONTROL EQUIPMENTS company, but apparatus expensive is equipped 200 tons storage, about 6-10 ten thousand RMB of ethylene removal equipment investment.
Summary of the invention
In order to overcome existing oxidizing process and the deficiency of the catalysis method of heating, the invention provides a kind of equipment that removes ethene, the know-why that is adopted has the advantages that oxidizing process is with low cost and the high-temperature catalytic method turns round continuously automatically, removal efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is: each fixes an electrode plate in upper and lower both sides, ethylene removal chamber, and the upper electrode plate feeds negative direct current high voltage, lower electrode plate earthing.After connecting power supply, the indoor electrion of ethylene removal produces ozone with the ethene oxidation Decomposition.
The invention has the beneficial effects as follows to have the advantages that oxidizing process is with low cost and the high-temperature catalytic method turns round continuously automatically, removal efficiency is high, its equipment cost of primary Calculation has only about 20% of import equipment.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
(1) negative high voltage power source module among the figure, (2) output cathode of power module (ground connection), (3) power module output negative pole, (4) ammeter, (5) voltmeter, (6) gas ionization passage negative plate, (7) supply fan, (8) air inlet pipe, (9) gas ionization passage positive plate (ground connection), (10) needle electrode on the positive/negative plate, (11) outlet passageway, (12) storage.
The specific embodiment
During equipment work, connect the power supply of negative high voltage module (1), on gas ionization passage negative plate (6), be added with negative high voltage, gas ionization passage positive plate (9) ground connection.Gas in the air conditioned storage storehouse is indoor through supply fan (7) importing gas ionization passage negative plate (6) and the formed ethylene removal of gas ionization passage positive plate (9), this air chamber produces a large amount of ozone and makes the ethene oxidation Decomposition, and the gas that removes behind the ethene returns the air conditioned storage storehouse through outlet passageway (11).
In this equipment, the output voltage and the electric current of negative high voltage power source module (1) are adjustable; Distance between gas ionization passage negative plate (6) and the gas ionization passage positive plate (9) is adjustable, and the flow of supply fan (7) is adjustable.
