Abstract

The utility model relates to an air purifying device, which is formed by a machine casing, a pipeline, a filter, a fan and the like components. The pipeline is connected with a machine body; liquid is contained inside the machine body; the position of the liquid reaches a certain liquid surface inside the machine casing; the fan is installed on the upper portion inside the machine casing; a filter screen is installed on the lower portion inside the machine casing; and a circulation water pump is installed inside an external pipeline communicated with the machine body. The air purifying device is capable of effectively collecting dusts and floaters suspending in air, particularly tiny dusts which can not be treated by other solutions, separating toxic and harmful substances, resolving the problems of dust lung, atmosphere pollution and environmental pollution, improving living space of human beings, protecting environment, and enhancing air quality.

Description

Air cleaning unit

Technical field

The utility model relates to the purifier of toxic and harmful in a kind of dedusting, the separation of air, belongs to International Classification of Patents A61L technical field.

Background technology

The pollution of the aerial superfine little dust of separate out suspended, particle is the technical barrier that is perplexing environmental protection industry (epi) for a long time always.In the prior art, generally adopt filter screen and fiber bag precipitator, its principle is similar to throw the net catches big fish, can only capture the fish bigger than mesh, and miss the fish littler than mesh.Above-mentioned principle is used for dust arrester, can only open the bigger dust of appearance and size, particle and air separation, and short grained dust has been fallen in careless omission, thereby has influenced clean-up effect.Being example with the cyclone dust collector again, is utilize centrifugal force that air and dust, particle produce in the high speed rotary course poor, and dust is separated from air with particle.But because of its quality convergence equates, the centrifugal force difference of generation is very little, is subjected to the restriction of rotary speed and other multiple factor, makes the power consumption height of this dust arrester and weak effect.Spray for another example and water-bath type dust cleaner, because the contact area of dust and the particle and the aqueous solution is restricted, attachment distance is excessive mutually.Contain the air of dust, particle and the proportion of the aqueous solution and differ bigger, above air floated over, the aqueous solution was difficult to hold mutually comprise below, does not also reach good dust removing effects.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and the air cleaning unit of a kind of energy-saving convenient, good purification is provided.

The purpose of this utility model is achieved through the following technical solutions.

Air cleaning unit comprises the parts such as pipeline, filter and blower fan of casing, connection, is that liquid---water is housed in casing, and liquid position reaches the liquid level in the casing, and blower fan is housed in device, drives air guided flowing.Screen pack is equipped with in bottom at liquid level; And in the external pipe that is communicated with body, be provided with water circulating pump.

Described screen pack adopts the macromolecule melt-blowing nonwoven to make.

The utility model can effectively be collected and be suspended in airborne dust and floating thing, particularly the insoluble micronic dust of other measure; Separate poisonous and harmful substance, alleviate its pneumoconiosis that brings, atmosphere pollution and problem of environmental pollution, improve the space that we depend on for existence, the protection environment improves air quality.

Description of drawings

Accompanying drawing is the structural representation of the utility model air cleaning unit.

Among the figure: 1, casing, 2, water circulating pump, 3, screen pack and carriage, 4, liquid level, 5, blower fan, 6, pipeline.

The utilization of lines: heavy line is represented shell and wind isolation board; Middle heavy line is represented circulating water pipe; The liquid level position of the aqueous solution is represented in double dot dash line; Dotted line is represented the position of carriage and screen pack; Arrow is represented the flow direction of air.

The specific embodiment

Referring to accompanying drawing, air cleaning unit of the present utility model comprises casing 1, the pipeline 6 that connects, filter 3, blower fan 5 etc., in the casing 1 liquid is housed---water, it above the bottom aqueous solution sedimentation basin that contains the dust granules thing, liquid position has reached the liquid level 4 in the casing 1, on the top of casing blower fan 5 is housed, screen pack 3 is equipped with in the bottom of liquid level 4; In the external pipe 6 that is communicated with body, be provided with water circulating pump 2.Screen pack 3 is made by the macromolecule melt-blowing nonwoven.

The utility model utilizes the macromolecule melt-blowing nonwoven to do screen pack 3, be provided with the aqueous layer of enough degree of depth on screen pack 3 tops, be specifically designed to collection, separation, filter the dust, the particle that are suspended in various sizes in the air, and be contained in the poisonous and harmful substance of the aqueous solution or water-soluble solution, implement harmlessness disposing.The macromolecule melt-blowing nonwoven has three big characteristics: 1) good permeability, and the filtered air resistance is less; 2) aperture is less, is convenient to isolate less relatively dust of size and particle; 3) has stronger hydrophobicity, the aqueous solution can not be penetrated under capillary effect easily, have only under the situation of active force greater than water surface tension, the aqueous solution could pass through screen pack, and this just provides the foundation for the solution layer that certain depth is set on this material.Can set up a carriage in the bottom of screen pack, prevent that big pit from appearring in middle body.

During operation, in casing 1, add the aqueous solution earlier, start water circulating pump 2, the aqueous solution is transported on the screen pack 3, the liquid level 4 of the degree of depth greater than 30 millimeters smooth flow is set through pipeline 6.Start blower fan 5, in casing 1, form negative pressure, suck the poisonous and hazardous air that contains dust and particle, appearance and size is come out greater than the dust and the particulate separation of mesh in the screen pack bottom.When the less dust of appearance and size and particle when " brill " crosses mesh under the carrying secretly of air, promptly be divided into tiny air-flow and enter in the aqueous solution by mesh, contained by the aqueous solution.At this moment, with nearer distance, bigger area adheres to chance more mutually and mixes between dust, particle and the aqueous solution.The dust, the particle that are attached to the aqueous solution are contained in the water easily, become clean air after losing the air emersion aqueous solution of dust, particle, discharge casings 1 by blower fan 5.Dust and the particle suitable with the pore size of filter mesh, may be embedded in the mesh during by mesh or stopped up mesh, influenced the operate as normal of screen pack, solution is regularly an opposite spin blower fan 5, changes the blast direction, forms malleation in casing 1, the aqueous solution is come out from the screen pack extruding, the aqueous solution is gone out tamper during by screen pack, falls into the water, to recover the normal function of screen pack.The dust that falls into the water, particle under the capillary protection of the aqueous solution, are collected into aggregate and precipitate in the pond, and other does disposal.

For increasing the capacity that air cleaning unit purifies air, adopt sandwich construction as shown in the figure, realize dilatation by the method that increases the screen pack filter area.

In this device, can such as the processing of stone field of filling the air at dust, rescue and relief work scene, battlefield etc., prepare the corresponding aqueous solution according to the characteristics of air in the particular space, with airborne poisonous and harmful dust granules thing generation chemical reaction, with targetedly, purify air better.
