Description

Ethene purifier

The present invention relates to a kind of fruit and vegetable using freshness preserving equipment, especially in order to remove the device of ethene and other foreign material.

Ethene plays an important role in preserving fruit and vegetable utilizing, it is the kind of plant hormone that accelerates the ripening, its growing amount system of digging and regulating aging course, and its promotes fruit maturation and chlorophyll to decompose, stimulate respiratory intensity and some oxydase, lytic enzyme, accelerate oxygenizement and consume a large amount of substrate of respirations.A large amount of generations of endogenous ethylene have started the maturation of fruit in the fruits and vegetables, endogenous ethylene forms exogenous ethylene after being diffused into the space, the tired generation that further stimulates endogenous ethylene of the storehouse inner product of exogenous ethylene, therefore, the key of storage fruit and vegetable is constantly to eliminate exogenous ethylene in the storehouse, reach no ethene storage, and dig the system endogenous ethylene under the concentration that causes after-ripening, dig the generation of having made ethene and also just dig system ripening and senescence process, and some present means of hoard and equipment all can not be accomplished the system of digging to ethene effectively, just lack effective ethene treating plant.

Existing ethene treating plant, ethene as gondola ethylene removal system and Britain is eliminated system, its structural principle is an oxidizing fire when making ethene high temperature with palladium or platinum as catalyzer, this kind equipment exists heat effect, the cost height, efficient is low, weak effect, it is not thorough to the external source ethylene removal, does not have removal effect to influencing the ripe old and feeble principal element-endogenous ethylene of fruits and vegetables.

The objective of the invention is to overcome the defective that said system exists, change principle of design, utilize the radiation exposure principle to produce ozone and negative ion, obnoxious flavour in the newborn oxidizing gas direct oxidation storehouse.Provide a kind of simple in structure, with low cost, economical and energy saving uses efficient and the double multi-functional ethene treating plant of doing his usefulness.

Ethene purifier produces ozone and negative ion, ozone is the strong oxidizer that is only second to fluorine, negative ion has electric charge, this device is connected with pipeline and refrigerator chamber, constitute closed gas circulation route, and electricity consumption fans drive airflow circulation, the obnoxious flavoures such as ethene that contain in the storehouse are sent in the ethene purifier, part obnoxious flavour directly is ionized, a part is fallen by ozone oxidation, remaining ozone and anion gas are sent into storehouse and are made it the concentration that keeps certain, and ethene exhaustive oxidation in the storehouse is fallen, and realize no ethene.

Ozone and negative ion are produced by ozone anion generating pipe [50] in the ethene purifier, some of generating pipes [50], parallel connection on the line, after connecting power supply, plus high-voltage field is produced by high pressure producer [01], put on the generating pipe [50], just produce glow discharge, gas is in electrode aluminium net generation ionization, produce ozone and single polarity negative ion, finish software journey treatment input computer according to adopting back fruits and vegetables characteristic and freezer particular case, as required the time key on the keyboard is pressed, can carry out journey and treat control.

The ozone anion generating pipe is by sealing cap [51], aluminium net electrode I [52], Glass tubing [53], electrode II [54] and Glass tubing electrode anchor [55] constitute, Glass tubing electrode anchor [55] is welded in one on the left side when burning glass, the electrode II is welded in the right, and the surplus pipe of bleeding is reserved on the left side, with vacuum pump the gas in the Glass tubing [53] is evacuated to 1 * 10 ^-6MmHg; return town's argon nitrogen helium rare gas element again as starting gas and shielding gas; make the interior vacuum tightness of pipe reach 0.2mmHg; live the left side with flame sealing and seal, remove the surplus pipe of bleeding, two glues sealing cap [51] with Resin adhesive; Glass tubing [53] overcoat electrode aluminium net [52] centerlock; aluminium net length is not less than 20mm apart from sealing cap [51], so just becomes an electrical condenser, and the ozone anion generating pipe of some (as 10) same specification is parallel in the circuit.

Ethene purifier is by inlet pipe [1], strainer [2], CO ₂Absorption device [3], the fan [4] of supplying gas, contact ionization chamber [5], oxidation reaction chamber [6] and escape pipe [7] are formed.Inlet pipe [1] and escape pipe [7] are plastics tubing, are used to supply gas, and the interior glaze cotton of strainer [2] filters the impurity in the gas of sending in the storehouse; CO ₂Dress Ca(OH in the adsorber [3]) ₂, make the CO in the storehouse ₂By Ca(OH) ₂Absorb, blowing fan [4] drives air cycle, and exposure chamber [5] make gas ionization on the interface of sending into, O under ozone anion generating pipe glow discharge situation ₂Molecule is dissociated into Sauerstoffatom, ethene, ethanol, acetaldehyde also are ionized to his thing, and pathogenic microorganism is killed by the ultraviolet ray that glow discharge generates, and oxidation reaction chamber [6] is a space chamber, Sauerstoffatom is combined into ozone in oxidizing chamber, residual ethene and germ be further oxidation in oxidizing chamber.

Fig. 4 is connected in storehouse with ethene purifier, and is fresh-keeping in order to the fruits and vegetables storehouse.Wherein ionization chamber links in oxygen cylinder [8] and the cleaner, directly supply with pure oxygen and produce ozone, improve output takes place, temperature adjustment air inlet port [9] is in order to introduce cool ambient air, agitation fan [10] is in order to stir air, eliminate temperature, humidity and gas concentration gradient, exhaust fan [11] is used for ventilation, and vent [12] is pressed on storehouse top, the top is by adorning a rigid foam ball with the venting hole same specification valve [13] that rises, and be fixed on the storehouse by connecting rod [14], but uncontrolled fluctuation in price, when there is low-temperature receiver in the external world, can stop refrigerator, finish the work of ventilation and attemperation by temperature adjustment air inlet port [9] and exhaust fan [11].

Ethene purifier mesohigh producer output voltage is 8000V, frequency 50HZ, power 100W, the ozone anion generating pipe is directly through 40mm, long 400mm, electrode the worker make of stainless steel, diameter 5mm, when high pressure producer output 8000V high pressure is added on the ozone anion generating pipe, glow discharge takes place, corona light and corona wind occur, gas is dissociated into Sauerstoffatom and single polarity negative ion in the plumbous online ionization of electrode II, the ionization indoor gas is sent into the oxidizing chamber Sauerstoffatom by fan and is combined into ozone, and the ethene in the gas is oxidized.

The characteristics of ethene purifier are to produce and to discharge pure ozone of a large amount of matter and negative ion, ozone can not only oxidize away interior exogenous ethylene, also can and penetrate into sporocarp simultaneously by diffusion, abolish ethene in the tissue, ethanol, objectionable impuritiess such as acetaldehyde, bacterium, virus, bacterium, pollutents such as remains of pesticide also can be oxidized fall, and in the negative ion energy and the fruit electric charge, have reduced biopotential, starting enzymic activity and positive charge have been reduced, stoped the after-ripening decay thereby reduced respiratory intensity, so ethene purifier is used for preserving fruit and vegetable utilizing and has pluralistic function, fresh-keeping effect is splendid.
