Abstract
The invention discloses a dust collector for purifying air. The dust collector comprises a shell, an air inlet, an air outlet and a motor, wherein the air inlet and the air outlet are formed in the shell, and the motor is arranged in the shell. The shell comprises an upper shell body and a dust collecting container. The upper shell body is fixed to the dust collecting container. The dust collector further comprises a cyclone filter which is arranged in the shell and filters air entering the dust collector. The cyclone filter is provided with a filter element. A filter paper tube is composed of two filter paper layers and a catalyst layer sandwiched between the two filter paper layers. While the filter element of the dust collector filters dust, the pollutant content in the air in a room is reduced.
Description
Technical field
The present invention relates to dust catcher and technical field of air purification, be specifically related to a kind of dust catcher purified air.
Background technology
Dust catcher can be divided into vertical, horizontal and portable by structure.The operation principle of dust catcher is, utilizes motor band moving vane High Rotation Speed, in the housing of sealing, produce air negative pressure, draws dirt bits.
Dust catcher, primarily of playing dirt, dust suction, filter dirt three part composition, generally comprises series excitation commutator motor, centrifugal fan, dirt catcher (bag) and dust suction annex.The power of general dust catcher is 400-1000W or higher, and the power of portable dust collector is generally 250W and following.The dedusting of dust catcher energy, is mainly that its " head " is equipped with an electric exhaust fan.The rotating shaft of air exhauster there is fan blade, after energising, air exhauster can produce extremely strong suction and pressure with the rotating speed of 500 circles per second, under the effect of suction and pressure, air is discharged at a high speed, and the air of vacuum part, blower fan front end constantly supplements the air in blower fan, dust catcher inside is caused to produce instantaneous vacuum, form Negative Pressure Difference with external atmosphere pressure, under the effect of this pressure reduction, suck the air containing dust.Dust and other impurities enters bag dust filter by carpet or floor cleaner brush, long pipe, bend pipe, flexible pipe, hose coupling successively, and dust and other impurities is trapped in bag dust filter, and air after filter disc purification, then is discharged by body afterbody.
The operation principle of dust catcher is motor of dust collector High Rotation Speed; air is sucked from suction inlet; dirt case is made to produce certain vacuum; dust enters the bag dust filter in dirt case by scrubbing brush, adapter, handle, flexible pipe, main suction pipe; dust is left in bag dust filter; air after filtration enters motor through one deck filter again; this layer of filter prevents the dirt bag dust that breaks from sucking one protective barrier of motor; the air entering motor flows out through motor; because in motor operation, carbon brush constantly weares and teares, add again before therefore flowing out dust catcher and filtered together.Filtering material is finer and closely woven, and just air filtration can be obtained dust catcher cleaner, but air permeability is poorer, have impact on the air quantity that motor sucks like this, reduces dust catcher efficiency.Its air permeability is lower, therefore all does waviness to increase vapor permeation area.
But existing dust catcher filter element, the main consideration of its design is filter dust.But in current indoor environment, owing to being rich in a large amount of gaseous state and fume in air, these gaseous states and fume are attached on dust granule.When dust suction, it is from dust granule surface desorption, thus reenters the gas of indoor environment, causes air again to be polluted.
