Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 1, an intelligence energy-saving water curtain formula lampblack absorber for house, including purifying box 1, be equipped with a plurality of purge tubes 2 in the purifying box 1, the pipe wall of purge tube 2 is equipped with a plurality of tiny through-holes 21, the lower extreme fixedly connected with gas collecting channel 3 of purifying box 1, the upper end of purifying box 1 can be dismantled and be connected with air exhaust hood 9, the lateral wall fixedly connected with purifying cylinder 5 of purifying box 1.

It should be noted that, because the aperture of the fine through hole 21 on the wall of the purification tube 2 is very fine, the aqueous solution in the purification box 1 cannot flow into the purification tube 2 through the fine through hole 21 under the surface tension of the liquid. Thus, the cleanness of the aqueous solution in the purifying tank 1 can be ensured.

Through intake pipe 4 intercommunication between the interior bottom of purifying cylinder 5 and the interior top of exhaust hood 9, just install first check valve in the intake pipe 4, through back flow 6 intercommunication between the interior bottom of purifying cylinder 5 and the purifying box 1, just install the second check valve in the back flow 6, the embedded filter screen 61 that is equipped with of back flow 6, install exhaust tube 7 on the lateral wall of purifying cylinder 5.

The first check valve allows only gas to be discharged from the purge tube 2 into the purge cylinder 5, and the second check valve allows only liquid to be discharged from the purge cylinder 5 into the purge tank 1.

During the working process of the device, when the air exhaust pipe 7 connected with an external air extractor performs air exhaust, negative pressure can be generated in the purifying cylinder 5, so that oil fume gas can flow into the purifying pipe 2 from the air collecting hood 3 and is exhausted into the purifying cylinder 5 through the air inlet pipe 4, the gas in the purifying pipe 2 has high flow speed and low pressure intensity, liquid outside the purifying pipe 2 hardly flows and the pressure intensity is high, so that pressure difference can be generated inside and outside the purifying pipe 2, aqueous solution in the purifying box 1 can be extruded into the purifying pipe 2 through the fine through holes 21, meanwhile, the aqueous solution extruded through the fine through holes 21 is in a droplet shape and can be fully mixed with the oil fume gas in the purifying pipe 2 to achieve the purification purpose, the oil fume gas mixed with the aqueous solution in the purifying pipe 2 is gradually cooled and enters the purifying cylinder 5 along with air flow, and is simultaneously mixed with the aqueous solution in the purifying cylinder 5 again and is thoroughly cooled, grease in the oil fume gas is partially condensed into liquid and floats on the liquid level, other purified gases are exhausted from the exhaust pipe 7.

Along with the continuous use of the device, the liquid level in the purifying cylinder 5 also rises continuously, due to the action of the second one-way valve, the water solution in the purifying box 1 cannot flow into the purifying cylinder 5, when the liquid level in the purifying cylinder 5 is higher than the liquid level in the purifying box 1, under the action of hydraulic pressure, the water layer 102 below the liquid level in the purifying cylinder 5 passes through the return pipe 6 and is discharged into the purifying box 1 again after impurities in the oil smoke are filtered by the filter screen 61, because the grease content in the oil smoke is far less than the water solution filled in the purifying cylinder 5 in the initial state, most of the liquid in the purifying cylinder 5 is water, and the oil layer 101 floats above the liquid level, so the oil layer 101 cannot flow into the purifying box 1. Therefore, the water resource in the device can be recycled, and only the detergent is required to be put into the purifying box 1 regularly.

Example two:

referring to fig. 2-3, different from the first embodiment, a liquid storage cavity 51 is formed on a side wall of the purification cartridge 5, a liquid inlet 52 is formed on an inner wall of the purification cartridge 5, a hollow buoyancy block 8 is slidably connected to the inner wall of the purification cartridge 5, and the hollow buoyancy block 8 is suspended on an oil-water layer line.

In the initial state, a certain amount of water is filled in the purification cartridge 5, and the liquid level in the purification cartridge 5 in the initial state is lower than the liquid inlet 52.

Further, the side wall of the purifying cylinder 5 is also provided with a liquid outlet which is the same as the liquid storage cavity 51, and a valve is arranged in the liquid outlet so as to conveniently take the grease in the liquid storage cavity 51 at any time.

In this embodiment, when the liquid level in the purification cylinder 5 rises to the liquid inlet position, the oil layer 101 located above the liquid level flows into the liquid storage cavity 51 through the liquid inlet 52, and if the oil layer 101 in the purification cylinder 5 flows out, the liquid level in the purification cylinder 5 continues to rise, the hollow buoyancy block 8 on the suspension and oil-water separation layer line can block the liquid inlet 52 at this moment, the water layer 102 can be prevented from flowing into the liquid storage cavity 51, so that the oil-water separation can be performed on the purified water solution, and the treated grease can be recovered and stored, so that the grease can be processed and utilized later.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
