Detailed Description
Example 1:
the dust removing system as shown in fig. 1 and 3 comprises a shell 1, wherein a wet labyrinth adsorption area 7 and a dry labyrinth electrostatic adsorption area 8 are arranged in the shell 1;
a plurality of dry U-shaped structures 81 with mutually connected side edges are arranged in the dry labyrinth electrostatic adsorption area 8, and the dry U-shaped structures 81 extend from top to bottom;
the openings of the dry U-shaped structure 81 face the same side, an electrostatic electrode plate 83 is arranged on each opening side of the dry U-shaped structure 81, and the electrostatic electrode plates 83 extend into the openings of the dry U-shaped structure 81;
the electrostatic electrode plate 83 is electrically connected to the main control circuit board 6. The inventors found that the adsorptive dust removal effect generally follows the following law:
1-(1-q) n %；
wherein q is the dust removal efficiency of the single-stage dry U-shaped structure 81, and n is the number of stages of the dry U-shaped structure 81. The dust removal effect of the single stage dry U-shaped structure 81 is related to the electrostatic voltage, the spacing between the electrostatic electrode plates 83 and the dry U-shaped structure 81, and the air flow rate. The dust removal efficiency of the single-stage dry U-shaped structure 81 was found to be about 40% -80%. The excellent air grade of 0.16 mug/m can be achieved after the adsorption of the 8-grade dry U-shaped structure 81, calculated as the average value standard value of 24 hours PM2.5 under the severe pollution condition of 250 mug/m and calculated as the average efficiency of 60 percent. In combination with the treatment of the pre-stage wet labyrinth adsorption zone 7, the device of the invention can continuously provide purified air with excellent air grade. And by arranging the dry U-shaped structures 81 in an array, the purifying treatment capacity of the air can be greatly improved. The invention has the advantages that the invention does not need an unrecoverable filter element structure, the problem of filter element blockage and the problem of filter element pollution after a period of use are avoided, and the use cost can be greatly saved.

In this structure, the labyrinth formed by the dry-type U-shaped structure 81 and the T-shaped structure of the electrostatic electrode plate 83 forces the particles in the passing air to contact the electrostatic electrode plate 83 and the inner wall of the dry-type U-shaped structure 81, so that the particles are charged with static electricity and adsorbed by the dry-type U-shaped structure 81, thereby improving the dust removal effect, and the adsorption effect is greatly improved compared with the existing flat-plate electrostatic adsorption structure.
In a preferred embodiment, as shown in fig. 6, an electrostatic adsorption layer 87 is provided on the inner wall of the dry U-shaped structure 81; with this structure, the adsorption effect is further improved.
The electrostatic adsorption layer 87 is made of one or more materials selected from polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polycarbonate, dimethylformamide, methyl acrylate, polyacrylamide and polyethylene glycol. Compared with the negative electrode plate structure made of metal in the prior art, the electrostatic adsorption layer 87 made of plastic has better adsorption effect. In particular, the interval time of each cleaning can be prolonged.
The preferable scheme is as shown in fig. 3, and adopts a scheme of multiple rows of parallel arrangement, so that ventilation can be increased, treatment efficiency can be improved, or wind speed can be reduced, and adsorption effect can be improved.

The breather tube 82 communicates with the gas pump 12 via an insulated connection; to avoid interference of the gas pump 12 with the high voltage current. The insulating connector in this example refers to a connector made of plastic, such as a connecting tube made of nylon or polytetrafluoroethylene. The gas pump 12 is preferably a diaphragm pump or a piston pump.

The pressure sensor 15 is used for detecting the negative pressure of the purified air, and if the negative pressure exceeds the standard, the condition that the air path is blocked is reflected, namely, a cleaning program is started. When both the particulate matter sensor 14 and the pressure sensor 15 are provided, the feedback of the particulate matter sensor 14 is typically used only to start the cleaning process of the dry labyrinth electrostatic adsorption zone 8, while the feedback of the pressure sensor 15 is used to start the cleaning process of the wet labyrinth adsorption zone 7.

as shown in fig. 8, the main control circuit board 6 is provided with a boost circuit 61 and a bridge rectifier circuit 62, and a switch circuit 63 for bypassing the bridge rectifier circuit 62. When the dust removal works, the bridge rectifier circuit is electrically connected with the electrostatic electrode plate 83 to output half-wave positive current, and when the dry U-shaped structure 81 is cleaned, the booster circuit 61 of the main control circuit board 6 bypasses the bridge rectifier circuit 62 to directly output alternating current. The boost circuit 61 adopts an inversion chopper circuit to convert commercial alternating current into direct current, converts the direct current into high-voltage current of 5-6 kilovolts, then converts the high-voltage current into alternating current by using a thyristor, and converts the alternating current into half-wave positive current with the frequency of 4-50 khz through the bridge rectifier circuit 62 to form a pulse electrostatic field so as to reduce energy consumption while ensuring the dust removal effect. When the bridge rectifier circuit 62 is bypassed, high-voltage alternating current of 5-6 kilovolts is output, and is used for removing electrostatic fields, so that adsorbed particles can be cleaned conveniently.

The dust removal efficiency of the single stage wet U-shaped structure 71 is about 40% -80%. The excellent air grade of 0.16 mu g/m can be achieved after the adsorption of the 8-level wet U-shaped structure 71, calculated by the average value standard value of 24 hours PM10 under the severe pollution condition of 250 mu g/m and the average dust removal efficiency of 60 percent. In combination with the later-stage dry labyrinth electrostatic adsorption zone 8, high-quality air with average value of 0-1 mug/m of PM2.5 for 24 hours can be ensured, and the dust removal capacity can be increased by arranging the wet U-shaped structure 71 and the dry U-shaped structure 81 of more stages, so that the probability of adsorption falling is reduced, and the time of backflushing cleaning is delayed. Can greatly reduce the burden of an indoor respiratory tract system, reduce the occurrence probability of allergic rhinitis and improve the rest recovery effect of the indoor body function.

It should be specifically noted that in the description of fig. 1 and this example, only the preferred embodiments are described, and the positions of the wet labyrinth adsorbing zone 7 and the dry labyrinth electrostatic adsorbing zone 8 are not limited, that is, in some situations, the wet labyrinth adsorbing zone 7 is located upstream, and the dry labyrinth electrostatic adsorbing zone 8 is located downstream, for example, in the application situations in the south, the air is more humid, and thus the air with lower humidity is output. In the northern application scenario, the dry labyrinth electrostatic adsorption area 8 is arranged at the upstream, the wet labyrinth adsorption area 7 is arranged at the downstream, and air with higher humidity is output, so that the indoor air humidity is improved. It is possible to provide the fan 3 in the housing 1 as in fig. 1 or to provide the fan 3 in the side of the housing 1 as in fig. 4.
Example 2:
taking the structure of fig. 1 as an example, the use and control steps of the present invention will be described:
in use, the liquid box 9 containing the adsorption liquid is placed at the bottom of the shell 1, the air inlet panel 10 is removed, and preferably, a primary filter screen is further arranged on the air inlet panel 10 to perform primary filtration on air, and most of fibers, such as fibers falling off from textiles such as hair and clothes, are mainly blocked. The wet labyrinth adsorbing zone 7 is placed into the housing 1 from the position of the air inlet panel 10, and the bottom of the wet labyrinth adsorbing zone 7 is immersed into the adsorbing liquid of the liquid cartridge 9. After self-inspection, the fan 3 is started, and air is discharged from the air outlet channel 11 through the fan 3 after passing through the air inlet panel 10, the wet labyrinth adsorption area 7 and the dry labyrinth electrostatic adsorption area 8. In the wet labyrinth adsorption zone 7, dust is redirected multiple times in the labyrinth, and particles are contacted with the wet fluff adsorption layer 76 under the action of centrifugal force and adsorbed by the fluff adsorption layer 76. By the continuous adsorption, the specific surface area of the fluff adsorption layer 76 increases, and the adsorption effect can be further improved. The system has smaller wind resistance and can greatly improve the treatment efficiency due to larger through-flow section of the whole wet labyrinth adsorption area 7. When the pressure sensor 15 detects that the negative pressure is increased, that is, the through flow section is too small, so that the whole channel is blocked, the main control chip 60 controls the liquid pump motor 4 to act, the liquid pump 5 pumps the adsorption liquid in the liquid box 9 out, sends the adsorption liquid into the liquid pipe 72 and ejects the adsorption liquid from the liquid spraying port 73, so that the fluff adsorption layer 76 is washed, and collected dust is washed into the liquid box 9. Inside the liquid box 9 there are sedimentation means, such as sedimentation pipes or sedimentation plates, which utilize the shallow pool principle to sediment the dust. The line connecting the liquid box 9 with the liquid pump 5 is provided with filtering and/or overflow means to reduce the dust entering the line.
In the dry labyrinth electrostatic adsorption zone 8, the electrostatic electrode plate 83 outputs a pulse positive current through the booster circuit 61 and the bridge rectifier circuit 62 to form an electrostatic field, and when dust in the air passes through the dry labyrinth electrostatic adsorption zone 8, particles in the dust are positively charged due to the labyrinth structure and the centrifugal effect and are adsorbed by the electrostatic adsorption layer 87 connected with the negative electrode, so that the adsorption effect of small particles lower than PM10 is better. When the particulate matter sensor 14 detects that the particulate matter content of the air outlet duct 11 exceeds the standard, the main control chip 60 of the main control circuit board 6 controls the fan 3 to stop rotating, the switch circuit 63 is closed, the booster circuit 61 directly outputs alternating current, so that the electrostatic field is neutralized, and the adsorption force of the electrostatic adsorption layer 87 is reduced. And the main control chip 60 controls the action of the vibration device 16. Preferably, the vibration device 16 employs a vibrator driven by a piezoelectric element, so that dust falls from the electrostatic adsorption layer 87 and passes through the bottom plate of the perforated dry labyrinth electrostatic adsorption zone 8 into the liquid box 9. Or the main control chip 60 controls the fan 3 to reversely rotate, reversely blows dust to the wet labyrinth adsorption area 7, and simultaneously starts the air pump motor 13 to flush the electrostatic adsorption layer 87 from the ventilation branch pipe 86. The dust entering the wet labyrinth adsorption zone 7 is flushed by the liquid of the liquid pump 5 into the liquid box 9. Thereby completing the cleaning of the dry labyrinth electrostatic adsorption zone 8. After a period of use, for example 1-3 days, the air inlet panel 10 is removed, the wet labyrinth adsorption area 7 is taken out, the liquid box 9 is cleaned, and clean adsorption liquid is replaced. Before use, the electrostatic electrode plate 83 repopulates the electrostatic adsorption layer 87 of the dry U-shaped structure 81 to form an electrostatic field.
