Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, an embodiment of the present invention provides an integrated unit for kitchen oil smoke purification and heat energy recovery, which comprises a casing, the casing is divided into two parts, namely an oil smoke purification module 14 and a total heat exchange module 15. The oil fume purification module 14 is used for removing and purifying oil mist in the flue gas, and the total heat exchange module 15 is used for recovering heat in the purified flue gas, heating fresh air and discharging the fresh air to the indoor space for life in winter.

The shell is made of stainless steel. In order to improve the heat preservation function of the shell and avoid the heat of the smoke from dissipating when passing through the oil fume purification module, the inner wall of the shell is adhered with a polyethylene foam material for heat preservation and isolation. The joint of the sheet metal parts of the shell is sealed by long-acting sealing materials.

The oil fume purification module 14 is sequentially divided into a coarse filtration section 1, a high-voltage static module section 2 and an active carbon filtration network section 3 along the flowing direction of oil fume. The coarse filtering section 1 comprises a flow equalizing plate or a non-woven fabric, and the flow equalizing plate preferably adopts a multi-mesh stainless steel wire mesh and is used for blocking and collecting larger oil mist particles in the smoke. The kitchen oil smoke mist enters the oil smoke clarifier after being collected, and at first large oil drops and some impurity are adsorbed and filtered because of the inertia effect and the collision of flow equalizing plate, make the oil mist particle concentration greatly reduced after the preliminary treatment section of flowing out, have the characteristic of automatic oil leaching simultaneously, do not block up, and impurity coarse filtration section can be held back to guaranteed that the electric field normally works at the back, process the flue gas concentration after coarse filtration section filters is more balanced.

The residual small oil mist particles filtered by the coarse filtering section 1 enter the high-voltage electrostatic module section 2, the high-voltage electrostatic module section 2 comprises a polarization area (not shown in the figure) and a collection area (not shown in the figure), the polarization area is used for ionizing and polarizing the oil mist, the concentration of the smoke passing through the coarse filtering section 4 is relatively balanced, and therefore the smoke is highly ionized, decomposed and carbonized when passing through an electric field with certain high voltage, and a large amount of negative ions are generated, so that oil particles suspended in the oil smoke are charged, wherein the negative oxygen ions and oxygen in the electric field generate ozone, the disinfection and deodorization effects are achieved, and most of odor in the smoke is removed. The collecting region is used for collecting the oil mist after the ionization polarization, charged oil particles move to the collecting region under the driving of electric field force, and polar plates reaching the collecting region lose charges and are finally deposited on the dust collecting plate.

The oil smoke purified by the high-voltage electrostatic module 2 is finally converted into purified smoke after smell in the smoke is removed by the activated carbon filter screen 3. The purified flue gas enters the total heat exchange module 6 through the first smoke exhaust pipe 4.

It should be noted that the specific structures of the flow equalizing plate of the coarse filtering section 1, the high-voltage electrostatic module section 2 and the activated carbon filtering net 3 are the prior art, and do not belong to the innovation point of the utility model, and therefore, the detailed description is omitted.

Further, all still be equipped with oil drain pipe 11 on the lateral wall of coarse filtration section 1 and high-voltage static modular segment 2, be equipped with oil drain valve 12 on the oil drain pipe 11, the large granule oil drop after the separation in the coarse filtration section 1 and the tiny oil grain of entrapment in the high-voltage static modular segment 2 flow out through oil drain pipe 11 under the effect of self gravity.

The total heat exchange module 15 comprises a total heat exchanger, a first air inlet of the heat exchanger is communicated with the first exhaust pipe 4, a second air inlet of the heat exchanger is communicated with external fresh air through a fresh air inlet pipe 5, and the first exhaust pipe 4 is perpendicular to the fresh air inlet pipe 5; the first air outlet of the heat exchanger is communicated with the first air inlet, and the second air outlet of the heat exchanger is communicated with the second air inlet; and fans 7 and 8 are arranged at the first air outlet and the second air outlet. The first air outlet discharges the flue gas after purifying and cooling to the atmosphere through the second exhaust pipe 9, and the second air outlet discharges the new after heating to the indoor through the exhaust pipe 10.

In order to purify the fresh air, a fresh air coarse filter screen 13 is arranged in the fresh air inlet pipe 5.

As shown in fig. 2, the cooking oil fumes sequentially pass through the coarse filtration module section 1, the high-voltage electrostatic module section 2 and the activated carbon filtration network section 3 of the integrated unit and then enter the total heat exchange module 6 through the first exhaust pipe 4, and fresh air enters the total heat exchange module from the fresh air inlet pipe 5 to perform total heat exchange with the purified oil fumes. The processed high-temperature oil smoke and the outdoor fresh air exchange heat in the heat exchanger, and the second exhaust fan 8 forcibly sends the outdoor fresh air which is heated after being filtered, purified and heat exchanged into the room through an exhaust pipe 10. The first exhaust fan 7 exhausts the filtered, purified and heat-exchanged kitchen oil smoke out of the room through the second exhaust pipe 9. When the air conditioner operates in winter, the fresh air obtains heat from the exhaust air, so that the temperature is increased. The heated fresh air is sent into the room, so that the waste heat in the high-temperature oil fume in the kitchen is effectively utilized.
