Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 to 3, a dust device, including organism 1, a plurality of filter module 4, just strain subassembly 5 and fan B6, processing has through-hole B14 on the organism 1, the processing of the below at through-hole B14 has water storage box 12 in the organism 1, water storage box 12's top is through a plurality of through-holes A13 and through-hole B14 intercommunication, fan B6, just strain subassembly 5 and a plurality of filter module 4 and install in proper order in through-hole B14. When the dust-settling air purifier is used, air containing dust is sucked into the through hole B14 through the fan B6, the air containing dust is purified by the primary filter assembly 5 and the filter assemblies 4 in sequence and then is discharged from one end, far away from the fan B6, of the through hole B14, and therefore the dust-settling purpose is achieved. Because the device adopts the linear dust removal mode, the wind resistance is relatively small, and the dust settling efficiency is high.

The through hole B14 is internally provided with a fan A2 at one end far away from the fan B6. The air purified in the through hole B14 is pumped out through the fan A2, the flow speed of the air in the through hole B14 is improved, the handling capacity of the device for dust-containing air in unit time is improved, and the dust settling efficiency is high.

And the fan A2 and the fan B6 are both negative pressure fans.

The primary filter assembly 5 is a stainless steel filter screen. The dust-containing air is primarily filtered through a stainless steel filter screen.

And 1-3 filter assemblies 4 are arranged in the through hole B14. The number of filter assemblies 4 can be increased or decreased according to the actual dust fall effect of the device.

The filtering component 4 is a cooling water curtain. The cooling water curtain is a paper honeycomb structure, and is not described herein for the prior art. When the cooling water curtain is used, the metal frame is installed on the outer circular surface of the cooling water curtain, and the outer circular surface of the cooling water curtain is protected through the metal frame.

The top of organism 1 is installed water supply assembly, and this water supply assembly's delivery port extends to the top of cooling cascade.

The water supply assembly comprises a water inlet pipe 8 and a plurality of water supply pipes 7, the water supply pipes 7 are installed on the machine body 1, water inlets of the water supply pipes 7 are communicated with the water inlet pipe 8 through connecting pipes 10, and a ball valve 9 is installed on the water inlet pipe 8. When the water supply device is used, the number of the water supply pipes 7 is the same as that of the filter assemblies 4, and the water outlets of the water supply pipes 7 extend to the top of the cooling water curtain, so that water is supplied to the cooling water curtain through the water supply assemblies.

And a water retaining ring 3 is arranged between the fan B6 and the primary filter assembly 5 and between the plurality of filter assemblies 4 and the fan A2 in the through hole B14. When the water storage tank is used, the through holes A13 are located between the two water retaining rings 3, water in the through hole B14 flows into the water storage tank 12 through the through holes A13, and the water retaining rings 3 are installed to prevent water from flowing out of two ports of the through hole B14.

The bottom of the water storage tank 12 is provided with a drain pipe 11. When in use, the drain pipe 11 is also provided with a drain valve, and sewage in the water storage tank 12 is discharged through the drain pipe 11.

Specifically, the through hole B14 is a circular through hole, and the center lines of the filter assembly 4, the preliminary filter assembly 5, the fan B6 and the fan a2 are coincident with the center line of the circular through hole B14.

A dust device, its theory of operation as follows:

starting a fan A2 and a fan B6, opening the ball valve 9, enabling water discharged from the water supply assembly to flow downwards from top to bottom under the action of gravity, and forming a water film on the fiber surface of the cooling water curtain; under the suction effect of fan A2 and fan B6, dusty air is inhaled in the through-hole B14, and through the stainless steel filter screen primary filter, then pass the cooling cascade, the dust in the air can be taken away to the water in the water film when dusty air passes the cascade to absorb the heat in the air, the air after the purification is discharged outside the device through fan A2, dusty sewage flows into in the water storage box 12 through-hole A13. Finally, the effect of high-efficiency dust fall and temperature reduction is achieved.

In summary, the blower B6 sucks the air containing dust into the through hole B14, the blower a2 extracts the air purified in the through hole B14, the flow rate of the air in the through hole B14 is increased, the handling capacity of the device for the air containing dust per unit time is increased, and the dustfall efficiency is high. Carry out the primary filter to dirty air through the stainless steel filter screen, the quantity of filter assembly 4 can increase and decrease according to the actual dust fall effect of device to guarantee that the device has good dust fall effect. Dirty air is just strained through the stainless steel filter screen, then passes the cooling cascade, and the dust in the air can be taken away to the water in the water film when dirty air passes the cascade to absorb the heat in the air, the air after the purification is discharged outside the device through fan A2, and dirty sewage flows into in the water storage box 12 through-hole A13, finally reaches the effect of high-efficient dust fall cooling.
