Description

Deodorization module and food waste treatment apparatus having the same

The present invention relates to a deodorizing module and a food treating apparatus having the same, and more particularly, electrolytic deodorization of the cooled condensate and cooling through heat exchange with respect to the hot and humid exhaust gas generated during the food processing in the drying furnace. The present invention relates to a deodorization module and a food treating apparatus having the same, which can effectively remove odors contained in the exhaust gas.

The food processor emits odor-induced gas of high temperature and high humidity during food processing, and it removes moisture and gas within a short time. Therefore, it is difficult to remove the odor. Especially, the freestanding type food processor is used to treat high temperature, high humidity and large amount of gas. Attention is rising. Currently, the most frequently used method is to remove odor gas using a method of treating exhaust gas using activated carbon and impregnated carbon and a high temperature catalyst reaction such as platinum. However, they do not meet the requirements of high temperature, high humidity, mass and short time treatment of the characteristics of the food processing gas. When the drying rate of the food processor is 80%, the high temperature vapor that is evaporated based on 1Kg is a large amount of 800CC, and depending on the pulverization drying method, the high temperature gas with the exhaust temperature of 60 to 80 degrees is treated in the filter. In just 1 to 5 hours, a large amount of odor gas is emitted. Due to the operating conditions of the food waste treatment system, the deodorization system using activated carbon is difficult to process a large amount of gas, and even after passing through the filter, the odor is generated. In addition, activated carbon does not exert deodorizing performance by blocking pores of activated carbon when it is impregnated with water. In general, activated carbon discharges the removed gas due to desorption phenomenon in which gas trapped in activated carbon is re-desorbed. And once every two to four months. In addition, the filter using a high temperature catalyst is to remove the gas by the platinum catalyst reaction by increasing the temperature of the gas discharged above 200 ℃ high power consumption and high temperature of the discharged air is high temperature air is discharged even if diluted. In addition, there is a disadvantage that the fine dust is discharged by the catalytic reaction to increase the temperature of the food waste treatment space. In addition, the replacement is required at least once a year, and the filter construction cost is limited to 3 to 10 times the manufacturing cost of activated carbon filter.

In order to solve the problems of high temperature, high humidity and discharge of large amount of water in a short time, the circulation condensation type food treatment method is devised. This method is a pulverization drying process in which the exhaust gas is dried after condensation of moisture by exhaust heat exchange. By recycling the inside of the furnace, only water is removed and discharged into the sewage pipe. However, the condensate generated at this time is a problem due to the backflow of odor when discharged to the sewer pipe as the odor gas is concentrated water. In addition, there is a drawback that the processing time is long because the moisture discharge is not smooth. In addition, in order to solve the odor problem of the condensate as described above, a method of deodorizing using an electrolysis method may be used, but in order to electrolyze the condensed water, an electrolyte or an electrolyte filter must be added, and thus maintenance costs There is a problem that this increases.

Hereinafter, an embodiment 150 of a heat exchange unit applied to the present invention will be described with reference to FIGS. 5 to 7. The heat exchange unit 150 may be heat-exchanged with each other by flowing the hot and humid exhaust gas from the upper inlet 141 and the cooling air supplied through the outside air inlet 144 from the outside in a direction crossing each other inside the heat exchanger 140. The unit heat exchange panels 153 and 155 may be stacked in a direction crossing each other. The unit heat exchange panels 153 and 155 may be stacked in directions perpendicular to each other.

The unit heat exchange panels 153 and 155 may be produced through a die casting process. The die casting is a precision casting method in which molten metal is injected into a mold of a steel machined to be precisely matched to a required casting shape, thereby obtaining castings identical to the mold. It is precisely dimensioned, has mechanical properties that do not need to be finished, and is capable of mass production.

On the other hand, the exhaust gas removed by condensation of water components while passing through the heat exchange unit 150 is re-supplied into the drying furnace 120 through a recovery pipe 147 disposed between the lower outlet 142 and the electrolytic cell 160. Go through the process.

In the heat exchange unit 150, unit heat exchange panels 153 and 155 are disposed in a stacked form between the first outer panel 151 and the second outer panel 152. The unit heat exchange panels 153 and 155 each have a first heat transfer fin 153a and 155a protruding in a bar shape while maintaining a constant distance on one side thereof, and a bar while maintaining a constant distance on the other side thereof. Second heat transfer fins 153b and 155b protruding in a shape, coupling protrusions 153c and 155c formed at edges of one surface thereof, and coupling protrusions 153c and 155c formed to correspond to edges of the other surface thereof. The fastening grooves 153d and 155d are provided. In this state, the second heat transfer fins 153b of the first unit heat exchange panel 153 and the first heat transfer fins 155a of the second unit heat exchange panel 155 are disposed in parallel to each other, and the first heat transfer fins 155a are disposed. The second heat transfer pin 153b is inserted into the space therebetween.

In each of the unit heat exchange panels 153 and 155, the direction in which the first heat transfer fins 153a and 155a and the second heat transfer fins 153b and 155b cross each other is formed. Preferably, the formation directions of the first heat transfer fins 153a and 155a and the second heat transfer fins 153b and 155b may be arranged in an orthogonal shape.

Referring to FIG. 7, it can be seen that the first heat transfer fins 155a and the second heat transfer fins 155b of the second unit heat exchange panel 155 protrude in a direction perpendicular to each other to form an internal flow path.

When the heat exchange unit 150 is stacked as described above, exhaust gas having a high temperature and high humidity flows from the exhaust unit 130 in the D direction, and cooling air flows from the outside in the E direction. The D and E directions indicate a flow direction orthogonal to each other, and the exhaust gas on the heat exchange unit 150 transfers heat energy to cooling air.

It is assembled to form narrower flow intervals with each other to increase the heat exchange efficiency. In the conventional case, the area of the high temperature fluid portion is smaller than the area of the cooling fin to increase the resistance of the fluid, and the contact area of the water vapor for condensation is small, so that the condensation efficiency is small. The area is secured more than five times as compared to the conventional one, and the flow path area is increased to reduce the flow resistance, thereby reducing the flow rate and consequently increasing the condensation efficiency.

Figure 8 is a perspective view of another embodiment of the heat exchange unit, Figure 9 is an exploded perspective view showing a state in which the cover member is coupled to the front and rear surfaces of the body constituting the heat exchange unit of Figure 8, Figure 10 is a cutting process for the side of the body A perspective view illustrating a state in which the second flow channel formed in the main body is exposed to the side surface of the main body, and FIG. 11 is a cross-sectional view taken along line FF of FIG. 10.

Hereinafter, another embodiment 150 ′ of the heat exchange unit applied to the present invention will be described with reference to FIGS. 8 to 11.

The heat exchange unit 150 ′ includes a main body 180 having a plurality of flow channels 181 formed therein and a cover member 190 fastened to both ends of front and rear surfaces of the main body 180. The fastening grooves 189 formed at the front and rear edge portions of the main body 180 and the fastening holes 191 formed at the corner portions of the cover member 190 are configured to correspond to each other, using a separate fastening member (not shown). Mutual coupling is achieved.

The main body 180 is a single member that can be produced through an extrusion process, so that a cross section at any point may be formed identically, thereby securing a product having a desired shape in a short time through the extrusion process.

The plurality of flow channels 181 may be selectively communicated with side surfaces of the first flow channel 182 and the main body 180 which function as a passage of the first flow fluid entering and exiting through the cover member 190. It consists of a flow channel 184. Referring to FIG. 8, the direction in which the first fluid flows through the front and rear surfaces of the main body 180 is the first direction 196, and the direction in which the second fluid flows through the upper and lower sides of the main body 180 is moved. The direction 198 may be defined. In the Cartesian coordinate system, the first direction may be set to the X direction and the second direction to the Y direction. Here, the direction setting for the first and second directions 196 and 198 is merely set to be orthogonal for convenience, and is not necessarily limited to being set to the orthogonal direction.

The first flow fluid flows into the rear surface of the main body 180 along the first direction 196 and is discharged to the front surface of the main body 180 through the first flow channel 182. In the process, the cover member 190 does not interfere with the flow of the first fluid.

The second flow fluid flows into the upper end of the side surface of the main body 180 in the second direction 198 and is discharged to the lower end of the side surface of the main body 180 through the second flow channel 184. Communication between the upper and lower ends of the main body 180 and the second flow channel 184 may be performed through cutting operations on the upper and lower ends of the main body 180. A constant step is formed on both side surfaces of the body 180 through the cutting process. The step refers to a height difference between the cutting surface 186 and the unprocessed reference surface 188. The second flow channel 184 is exposed to both sides of the main body 180 due to the step. do.

The cover member 190 prevents the second flow fluid from being discharged to the front portion of the main body 180, which covers a portion where the second flow channel 184 communicates with the front and rear surfaces of the main body 110. It becomes possible, forming a structure in which) closes. Here, the first and second flow fluid may refer to the exhaust gas from the exhaust unit 130 and the cooling air from the outside, respectively.

The cover member 190 has a through hole 194 formed in the first direction 196 to allow movement of the first flow fluid flowing into the main body 180. The through hole 194 may be formed by performing a piercing process on a metal plate using a press machine. The blocking unit 192 disposed between the through holes 194 prevents the second flow fluid from leaking through the front and rear surfaces of the main body 180. And, a sealing member (not shown) is attached to the inner surface of the cover member 190, it is possible to prevent the leakage of the flow fluid when the cover member 190 and the main body 180 is in close contact.

Meanwhile, the first flow channel 182 and the second flow channel 184 may be continuously arranged alternately in the main body 180 as shown in FIG. 11. That is, the second flow channel 184 is disposed on both sides of the first flow channel 182 so that the first flow fluid flowing in the first flow channel 182 and the second flow flowing in the second flow channel 184. Thermal exchange between fluids can occur smoothly. Here, a heat exchange fin 185 having a predetermined shape is formed between the flow channels 182 and 184 to enhance the heat exchange performance between the first and second flow fluids.

Referring back to FIG. 11, in the case of the second flow fluid entering the second flow channel 184 along the second direction 198, the flow process is streamlined due to the presence of the heat exchange fins 185. It proceeds in close contact with the surface of the second flow channel 184, which increases the mobility of heat through heat conduction between the flow channels 181. Here, the heat exchange fins 185 are alternately formed on both sidewalls of the second flow channel 184 along the second direction 198 in each of the second flow channels 184 to support the streamlined movement of the second flow fluid.

Flow channels 181 formed in the body 180 through the extrusion process is formed in a different length formed along the second direction (196). That is, since the second flow channel 184 is formed longer than the first flow channel 182 with respect to the second direction 196, upper and lower ends of the second flow channel 184 are formed in the first flow channel 182. It is formed closer to the side of the body 180 than). Here, the cutting process proceeds only to the extent that the upper and lower portions of the second flow channel 184 are exposed to the outside so that the upper and lower portions of the first flow channel 182 are not exposed.

In this state, the second flow fluid flowing through the upper end of the main body 180 passes through the second flow channel 184 and is discharged through the lower end of the main body 180. Due to the protruding shape of the heat exchange fin 185 in this process, the second flow fluid flows in a zigzag streamline shape inside the second flow channel 184 (see reference numeral 195 of FIG. 11).

As described above, the heat exchange unit 150, 150 ′ according to the present invention can increase the heat exchange performance between the exhaust gas and the cooling air by crossing orthogonal cross orthogonalities of the plurality of flow channels 152, 154, 182, and 184 disposed therein. have.

12 is a cross-sectional view showing the internal configuration of the electrolytic cell. Hereinafter, the configuration of the electrolytic cell 160 according to the present invention will be described with reference to FIG. 12. The electrolyzer 160 includes a hollow body 161, a cover 162 fastened to the top of the body 161, an electrode case 164 disposed in the body 161, and a cell cover covering the top of the electrode case 164. 163, a water level sensor 166 attached to the body 161 to the lower side of the electrode case 164, and a discharge pump 168 connected to the outlet 167 formed at the bottom of the body 161.

In the electrode case 164, the cell electrodes 165 including the anode cells 165a and the cathode cells 165b are alternately disposed. An electrically conductive porous filler 169 is filled between the anode cell 165a and the cathode cell 165b. The condensed water cooled in the heat exchanger 140 flows to the electrode case 164 to maximize the time of electrolysis and the electrolytic contact area along the inner flow path configured to be zigzag up and down. Under the above structure, each of the porous fillers 169 filled in the electrode case 164 acts as a bipolar electrode, thereby maximizing the electrode area and causing an electrolysis reaction in the entire electrode case 164 to cause unreacted odorous substances. Will be minimized.

In the charge bipolar electrolysis method of the present invention, only the cell electrode 165 having the opposite polarity is electrically supplied without direct electrical connection to the porous filler 169 so that the porous filler 169 is changed into a bipolar electrode. Increasing the number improves electrolysis performance. In addition, the porous filler 169 may increase deodorization efficiency by using an adsorption process using pores formed in itself using a material such as activated carbon or alumina.

1 to 12, the driving method of the food processing apparatus 100 according to the present invention will be described collectively.

With respect to the food waste put into the drying furnace 120, stirring and grinding processing by the grinding screw 121 are performed, and a drying operation by a heater (not shown) arranged in the drying furnace 120 is performed. Exhaust gas including odor generated in the drying furnace 120 is transferred to the heat exchanger 140 by the operation of the exhaust unit 130. In the heat exchanger 140, the hot and humid exhaust gas from the upper inlet 141 is exchanged with the cooling air introduced through the outside air inlet 144 from the outside. The exhaust gas dried in the heat exchanger 140 is resupplied into the drying furnace 120 through the suction tube 112 of the recovery line 147 and the intake and exhaust module 110, and the steam condensed in the heat exchanger 140. Moves to the electrolyzer 160.

Exhaust gas whose temperature is lowered due to the first heat exchange and cooling in the heat exchanger 140 is secondary to the high temperature exhaust gas flowing through the exhaust tube 113 in the suction tube 112 of the intake and exhaust module 110. Through the heat exchange process, the temperature rises slightly. By improving the thermal efficiency through the multi-stage heat exchange as described above, the utility in the condensation and heat recovery process is increased compared to the conventional.

The malodorous concentrate moved to the electrolytic cell 160 is a odor gas factor between the positive electrode cell 165a and the negative electrode cell 165b by the porous filler 169 by electrolytic and adsorption reactions. Removed. In this case, the electrolytic reaction does not occur locally on the surface of the cell electrode 165, but occurs in the entire space in the electrode case 164 including the porous filler 169. On the other hand, the condensate is not directly through electricity, but the pore of the porous filler 169 is small, so even at low voltage and current, it is possible to conduct electrolysis without the addition of an additional electrolyte.

The condensed water treated in the electrode case 164 is stored in the buffer space 161a inside the body 161. When the condensed water level reaches the first water level sensor 166a while the condensed water is filled on the buffer space 161a, the discharge pump 168 starts operation to discharge the condensed water through the outlet 167, When the water level reaches the second water level sensor 166b, the operation of the discharge pump 168 is stopped. This is to prevent the inflow of air to the discharge pump 168 is to ensure the reliability of the operation.

As described above, the present invention is to recover the waste heat from the food waste generated in the drying furnace 120 through the stacked heat exchanger 140 and via the electrolytic cell 160 which functions as a cooling double-electrode deodorizing device for the cooled condensate. This effectively removes the odor. By using the deodorizing module 170 consisting of the heat exchanger 140 and the electrolytic cell 160, the power required is significantly reduced compared to the prior art to reduce the required cost required to maintain the system.
