Abstract

The invention is a method that dust collector applies ultrasonic atomized water to filter, setting an ultrasonic atomizing device in the dust collector and using water spray atomized by ultrasonic to filter dirt. It heightens the filtering effect and eliminating secondary pollution during working and dirt-cleaning courses.

Description

Dust catcher utilization ultrasonic atomization water participates in the method for filtration

Technical field: the invention belongs to the dust catcher technical field.

Technical background: because existing dust catcher filter effect is not good, " secondary pollution " problem that is caused, cause many harm to the user, as: dust catcher at work, a large amount of fine dust that can't filter out is sent forth again in room air, and this upper respiratory tract system to human body causes adverse effect; In removing the process of filtering the dirt in the laying dust device, the part dirt that has been collected is scattered in again in the surrounding environment, cause the pollution of environment.

A kind of dust catcher utilization ultrasonic atomization water that the present invention proposes for the defective that overcomes above-mentioned prior art existence just participates in the method for filtration.

Summary of the invention:

The present invention is achieved by the following technical solutions:

In dust catcher, be provided with supersonic atomizer, utilize the water smoke after the atomizing of excusing from death ripple, participate in the filtration to dirt of dust catcher.Its operation principle is to pass through ultrasonic transducer; making water fogging becomes the water smoke that many fine liquid particles are formed; the surface area of the water smoke of this moment has been far longer than the surface area of original equal volume water; and this water smoke is passed in the dirty airflow path of dust catcher; fine and closely woven and the water fog particle that is evenly distributed promptly and the dirt particles in the dirty air-flow mix; together pass through the filtration of the filter of dust catcher; in this process; because the participation of water smoke has been arranged; at least three kinds have promptly been taken place; help improving the situation of dust catcher filter effect; 1; because dirt air-flow and fine and closely woven; the mixing of that be evenly distributed and the great water droplet of summation surface area; make that dirt and water droplet are bonding; most of micronic dust particle is adsorbed with water; thereby increased the volume and the weight of dirt self, this will help utilizing the filtration of the filter of corresponding dust removal by filtration principle to dirt, as: the cyclonic filter device; microporous filter etc.2, because fine liquid particles absorption in dirt and the water smoke has increased the viscous force characteristic of dirt self, thereby make and self be hunted down when filtering the laying dust device easilier, and difficultly taken away by air-flow.3, after water smoke is imported into and filters the laying dust device, will in filtering the laying dust device, large-area respective inner surfaces form lasting moistening moisture film effect, feasible easier being hunted down of dirt through wet surface, and take away after can not being dried.Owing to above 3 existence that can effectively improve the factor of filter effect different from the past, must improve the dust removing effects of dust catcher filtration laying dust device.

Through the water smoke behind the ultrasonic atomization, it is big to have grain density, even particle distribution, and the great advantage of particle summation surface area, and particle is in floating dummy status at short notice, easily mixes with air-flow.Because the existence of above advantage is arranged, and the water smoke optimum behind the ultrasonic atomization mixes with dirty air-flow, become the most effective a kind of mode that water participates in filtering and improving greatly filter effect that in dust catcher, feeds.This be general pass through mechanical pressure water be excited into fine liquid particles after, be sprayed into the mode in the dirty airflow path of dust catcher, or simple in the filtration laying dust device of dust catcher, add entry etc. the inaccessiable effect of mode.Really realized the practical effect of water filtration.Further set forth the inventive method content below in conjunction with Figure of description and embodiment.

Description of drawings: Fig. 1 is the structural representation of the inventive method;

Fig. 2 filters the top cover schematic diagram of laying dust device for dust catcher;

Fig. 3 filters the structure chart of the filtration laying dust container of laying dust device for dust catcher.

Specific embodiments:

Embodiment one, as shown in Figure 1, 2, 3, the inventive method is to be arranged on the atomizing that realizes water in the seeping container 2 by ultrasonic transducer 1.This seeping container 2 is set at the inside of filtering laying dust device 3, be provided with ultrasonic transducer 1 in seeping container 2 bottoms, seeping container 2 tops are provided with seeping container lid 4, are respectively arranged with moisture outlet 5 and air flow inlet 6 on seeping container lid 4, and moisture outlet 5 is connected with aqueous vapor conduit 7.On described filtration laying dust device 3, be respectively arranged with dirty air intake 8 and cleaned air outlet 9, at the top of filtering laying dust device 3 is to filter laying dust appliance cover 12, in filtering laying dust device 3, also be provided with dirt deposition chamber 14 simultaneously, inside in dirt deposition chamber 14, be to be fixed in the whirlwind water filtering barrel 10 that filters on the laying dust appliance cover 12, be provided with seeping container at an end of whirlwind water filtering barrel 10 and cover the tangential gas flow guide duct 13 that 4 upper spaces are connected, be provided with dirt outlet pipe 11 at the other end of whirlwind water filtering barrel 10.Before the work, in seeping container 2, add an amount of water, cover seeping container lid 4 then.During work, dirty air at first is imported into through dirty air intake 8 and filters in the laying dust device 3, the air-flow of a part enters from air flow inlet 6, promote and carry water smoke after ultrasonic transducer 1 atomizing, flow out from moisture outlet 5, mix with all the other a large amount of dirty air, through tangential gas flow guide duct 13, being tangential flows in the whirlwind water filtering barrel 10, owing to contain a large amount of fine and closely woven and water fog particle and water-dust mixture that the summation surface area is very big simultaneously in the air-flow, in whirlwind water filtering barrel 10, under the strong centripetal force and the acting in conjunction of centrifugal force, inner surface at whirlwind water filtering barrel 10 has formed the lasting moistening moisture film vortex of one deck soon, and water-dust mixture and micronic dust particle are promptly thrown to the inwall of whirlwind water filtering barrel 10, are caught by the moisture film vortex, after being filtered, unnecessary dirt and aqueous mixtures are discharged in the dirt deposition chamber 14 via dirt outlet pipe 11, and the clean gas after the filtration flows out from cleaned air outlet 9.
