The present invention relates to an apparatus for removing food waste salts, odors and moisture contained in food wastes by using an electrolysis and vacuum pressure providing apparatus, in particular, food wastes in the electrolytic cell. When DC power is applied, salt is decomposed into Na ions at the cathode and Cl ions at the anode, and ammonia (NH3), a synonym for odor generated from food waste and Cl gas generated during the salt decomposition process, is rapidly decomposed. Combined and converted to ammonium chloride (NH4Cl) to remove odors, food waste salt, odor removal and water dehydration apparatus and method for dehydrating the food waste water to a vacuum providing device to drain will be.

Currently, environmental pollution is a serious problem all over the world, and food waste is one of the main causes of such environmental pollution.

Therefore, in order to solve this problem, the policy of recycling food waste has been proposed, and if the method is largely divided, it can be divided into energyification and extinction of methane gas generated by composting, feed, and anaerobic fermentation. .

However, in the case of composting, the concentration of salinity (NaCl) is high, so the growth disorder of the plant due to the osmotic phenomenon and Na is replaced with Ca and Mg in the soil, and the grain structure of the soil is destroyed. It was impossible to compost food wastes without salt removal because oxygen supply became difficult due to poor supply and impeded the growth of crops.

In order to solve this problem, the average salinity content announced by the Rural Development Administration for food waste was 4.84%. Therefore, the salinity content of the compost established by the Rural Development Administration was set at 1% or less. The salt concentration can be reduced by mixing sewage sludge, but this is an increase in the production cost and the quality of the compost is deteriorated to produce another waste rather than compost.

In addition, even in the case of livestock feed, food waste is significantly higher than the optimum 0.3-0.5% of the salinity of the feed, which may cause poisoning of the feed livestock, and due to thirst, the water intake is increased so that the digestive absorption efficiency, and As the growth rate slows down due to the deterioration of meat quality, there is a problem that the amount of wastewater generated increases due to the large amount of urine excretion. Therefore, the salt concentration must be removed to 0.3-0.5% and then used as feed.

In addition, in the case of the energy of methane gas by anaerobic fermentation, the growth efficiency of methane gas is lowered because it impedes the growth of anaerobic microorganisms with low flame resistance, and there are many problems in composting due to the accumulation of severe odor and salt.

However, there has been no technology that satisfactorily removes salinity so far as domestic and foreign technologies. However, the present invention is a way to drastically remove salts. When this is described, the power supply device (shown in FIG. 7) When power is applied through 400, Cl anions are formed on the positive electrode plate 10 and Na cations are on the negative electrode plate 10, and as shown in FIGS. 5-6, the vacuum pressure of the vacuum pump 310 is reduced. By the gon gak ions are separated through the membrane (17), the positive and negative ions are combined in the drain passage (20) to recombine with salt and then forcibly extracted from the drain space (30) to the brine reservoir (320) regenerated salinity No food waste disposal method has yet been introduced that can reliably remove and remove odors and moisture from food waste at the same time.

The present invention is to solve the above problems, salinity, odor and food waste of applying the DC power to the positive electrode plate, the negative electrode plate treated with the separator, and two or more electrode plates arranged in its design It is possible to remove salinity and odor which is superior to any existing method by making a resource-processing device that treats moisture dramatically, and composting food waste by rotating the salt removal device by 180 degrees to make pure food unimaginable with current technology. Its purpose is to produce green first-class compost, the best existing organic compost, or GR-mark compost, which is managed by the Ministry of Commerce, Industry and Energy, and fertilize it on agricultural land.

One Cl ion is regenerated as salt in the drain passage 20 and introduced into the drain space 30.

In addition, in order to reinforce the rigidity of the electrolytic cell 100, the reinforcement stand 110 is formed at the edge, and the reinforcement plate 50 is also installed at the lower part to assist the rigidity.

Hereinafter, the structural means used to remove salt, odor and moisture of food waste will be described in detail.

The food waste electrolyzer 100 has a space portion therein and has a hopper-shaped square cylinder shape in which one side is opened, and a plurality of electrode decomposition electrode plates 10 disposed at predetermined intervals therein, and food waste storage space portion 40. ) Is alternately arranged, and further comprises a drainage drainage space 30 disposed in the lower portion, the electrolytic electrode plate 10 is further provided with a protrusion 15 in the lower side and the center surface It is possible to separate and detachable to the bottom surface formed a hole corresponding to the protrusion (15).

In addition, a power supply device 400 is installed in the side housing of the food waste electrolytic cell 100, and supplies power to the pole plate from the power supply device so that the pole plate can be electrolyzed.

The electrode plate 10 for electrolysis is supplied with electricity from a DC power supply in a state containing food waste, and serves to remove and convert the gas causing salt and odor included in the food waste by electrolysis. Assembling bolts 16 on both sides of a cover iron plate 14 perforated on a three-pin fork-shaped support iron plate consisting of a bar, an upper iron plate 11, a middle iron plate 12, and an edge iron plate 13; It is a fixed form, and is a structure in which a drain passage 20 for sucking water or salt (Na ions, Cl ions) and odors is formed therein.

The cover iron plate 14 serves as a positive electrode portion 10b or a negative electrode portion 10a as necessary, and a plurality of holes 20a are formed in a body, so that water or salt contained in food waste or Decomposed substances such as odor gas and the like to be discharged to the outside by the vacuum pump.

For convenience of description, an electrode plate having a negative electrode portion and a positive electrode portion absorbing salt and water will be described by way of example. The cover iron plate 14 is configured by being divided into a negative electrode portion 10a and a positive electrode portion 10b. In the negative electrode portion 10a and the positive electrode portion 10b, a plurality of holes 20a through which ions pass are formed, and the separator 17 is further coupled to the outside thereof, and the drain surface is disposed on the lower surface of the electrode plate 10 for electrolysis. A hole 121 is formed, and the vacuum pressure providing device 300 for discharging salt and gas to the outside through the hole 121 is further connected.

That is, the electrolytic electrode plate 10 is in the form of a hopper, and the salt or malodorous gas and water containing food waste are extracted into the drain passage 20 through the separator 17 and the perforated iron plate hole 20a. In the outer wall, a plurality of holes 20b are formed so that these ions are collected through the holes 20b into the drain passage 20.

On the other hand, when looking at the power supply method of the present invention by connecting the power supply to the first pole plate and the last pole plate to apply the plus and minus power, and when the power is applied to the first pole plate and the last pole plate as described above The electrode plate is electrically driven by repulsion.

The principle of the electricity supply method is that when the electricity is applied with a fluid such as food waste containing water in between, when the iron plate is placed in the middle, both sides of the iron plate are opposite to the polarity of the opposite electrode. It is the same principle.

In the present invention, plus and minus are supplied to the first electrode plate and the last electrode plate without applying electricity to all the electrodes as described above, so that the other electrode plates are automatically repulsed to form electrodes.

In addition, the separator 17 is formed in a bag shape surrounding the negative electrode portion 10a and the positive electrode portion 10b, respectively, and Na ions or Cl ions passing through the separator from food waste are introduced into the drain passage 20 to the outside. Extracted.

Of course, when the electricity is applied across one or two across the electric plate between them is the electrical properties are automatically exhibited by the repulsive force as described above.

A drain passage 20 through which salt, odor gas, and water is formed is formed inside the negative electrode portion 10a and the positive electrode portion 10b so that chlorine ions electrolyzed from the food waste pass through the cation-side separator 17 and are weak. HCl is produced, or the perforated positive electrode plate is wrapped with a nonwoven fabric to dehydrate water generated by electrolysis with a vacuum pump, and sodium ions are passed through the anion-side separator 17 to be replaced with NaOH.

The separator 17 may be made of various materials, but preferably made of a cloth or non-woven fabric of fiber material, and the fiber material not only maintains the movement of ions naturally but also once the collected ions fall out again. Because it is useful.

Therefore, in the present invention, the separator 17 is manufactured in the form of wrapping a nonwoven fabric.

The water drainage space 30 is a space in which salinity, moisture, and odor gas of the pole plate 10 are temporarily extracted by forcibly extracting the drainage passage 20. For this purpose, the drainage space 30 has a predetermined distance from the bottom surface of the food waste electrolytic cell 100. It is disposed between the bottom surface 110 and the diaphragm 120 of the electrolytic cell 100 in a spaced apart state.

That is, the food waste electrolyzer rotating device 600 is a device for rotating the food waste electrolyzer 180 degrees to discharge the food and water from which the salt and salt have been removed to the lower portion by the gravity action, the rotary rod (500) installed in the food waste electrolyzer 100 ) Is transferred to the step, and when the electrolytic cell 100 is located on the step, the food waste is discharged to the outside by inverting by 180 degree rotation.

At this time, the electrolytic cell is moved to the rotating device 600 is transferred to the orbital moving device 700, and then can be moved to the electrolytic cell rotating device 600 by using a separate heavy equipment such as a crane.

Looking at the operation of the present invention below.

First, when a direct current is applied to the negative electrode portion 10a and the positive electrode portion 10b constituting the food waste electrolyzer 100, chlorine ions in the food waste move through the separator 17 to the positive electrode portion 10b. Electrolytic oxidation water is generated, and sodium ions in the food waste move to the negative electrode portion 10a via the separator 17 to generate water and react NaOH.

In other words, chlorine ions move to the positive electrode portion 10b by the electric field of sodium chloride (salt) in the food waste, and sodium ions move to the negative electrode portion 10a to desalinate as salt is decomposed.

At this time, not only the salt is decomposed during the electrolysis process, but also harmful gases such as ammonia and sulfide gases, which cause odors generated from food waste, are decomposed and converted into ammonium chloride, hydrogen sulfide, and the like. Forced discharge by the operation of the providing device 300.

Desalination occurs by electrolysis as described above, and the concentration of salt is lowered below the required concentration, thereby discharging water remaining in the food waste. By operating the vacuum pump 310 of the present invention, the vacuum waste food waste electrolyzer ( When applied to 100) while forcibly discharging the salinity and moisture of the food through the electrode plate while forcibly discharging the gas.

On the other hand, since the electrolytic cell 100 of the present invention applies electricity by filling food waste, the electrode plate 10 for electrolysis may individually fail, and in order to solve this problem, the electrode for electrolysis in the present invention is a cartridge type. The plate 10 is manufactured in a cartridge type to facilitate separation or bonding from the electrolytic cell 100.

Therefore, if the electrolytic electrode plate 10 can be detached as necessary, it can overcome the inconvenience of having to replace the whole food waste electrolytic cell 100 when one electrolysis electrode plate 10 is broken. Will be.

As described above, the present invention removes 4-5% of salt contained in food waste to 0.1% or less, and dehydrates 90% or less of water to 70% or less, so far, organic composting can be performed only by food waste. It is a recycling process that recycles food wastes from the soil to the soil and recycles them, maximizing the use value of food wastes, where there is no place to go, and disposing them. Greening the whole country and removing the odors and harmful gas from food wastes, it provides the effect of drastically improving the working environment.

In addition, it is possible to replace only the broken part can minimize the maintenance cost.
