Five, has embodiment
Fig. 3 is the cross-sectional view of rotoclone collector of the present invention.
Rotoclone collector of the present invention comprises and utilizes inertia force to finish first dust arrester (10) of control of dust for the first time and utilize centrifugal force to finish second dust arrester (20) of the control of dust second time as shown in Figure 3; In order to allow the pollutant that flows into second dust arrester from first dust arrester be rotated, be designed to a space in cylindrical shape shell of the dust collector inside; The parallel installation with shell of the dust collector of first dust arrester also is installed in shell of the dust collector inside with first dust arrester; A terminal center that is installed in the inner side of shell of the dust collector of first dust arrester, outwards protrude from shell of the dust collector the other end; Air discharge pipe and pollutant outlet have been installed on the shell of the dust collector.The effect of air discharge pipe is the contaminated air that flows into second dust arrester, is discharged to the shell of the dust collector outside after the inner purification of shell of the dust collector; The effect of pollutant outlet is that pollutant is discharged from shell of the dust collector is outside; The air discharge pipe is installed in the peripheral side end of shell of the dust collector, and the pollutant outlet is installed in the peripheral opposite side end of shell of the dust collector.
At this moment, collision place is called noise spot (left direction shown in Figure 3) mutually between the pollutant that the mobile pollutant of the peripheral side end (21a) of shell of the dust collector (21) and the peripheral opposite side end of shell of the dust collector leak out, and air discharge pipe (23) is designed to than the more outside protrusion of noise spot.Specifically: a tip length (AL) of the inner air discharge pipe of installing (23) of shell of the dust collector and the ratio (AL/CL) of shell of the dust collector (21) length (CL) are designed to 55.5 ± 5%.An end diameter (AD) of the inner air discharge pipe of installing (23) of shell of the dust collector and the ratio (AD/CD) of shell of the dust collector diameter (CD) are designed to 50.0 ± 5%.
Even the pollutant that leaks out from the end (21a) of shell of the dust collector and between the terminal pollutant that flows of shell of the dust collector, mutual interference phenomenon occurs, because the optimum coefficient of the ratio of shell of the dust collector (21) and air discharge pipe (23) comes out through experimental design repeatedly, reveals away by the air discharge pipe so can stop pollutant.
In other words, even the strength of the pollutant that leaks out to the end of mobile pollutant revolving force of the end (21a) of shell of the dust collector and shell of the dust collector, owing to the phase mutual interference weakens, because a tip designs of air discharge pipe (23) becomes than the outside more longer (left direction shown in Figure 3 of noise spot, more longer), can not be flow into shell of the dust collector inside from an end of air discharge pipe (23) so weaken the pollutant of revolving force, and continue to be subjected to the influence of back pollutant (following a mobile pollutant) particle rotation power to flow into the pollutant outlet to terminal one of shell of the dust collector.
Here, for a tip designs of air discharge pipe (23) is become than the more outside protrusion of noise spot, at first the situation of GPRS noise spot in order to allow all size dust catcher all be suitable for, can obtain best design just should test many times.Not only will be appreciated that the length and the diameter of shell of the dust collector (21) and air discharge pipe (23), also should know the installation situation of air discharge pipe, just can obtain best design at shell of the dust collector.
As a result, best design should comprise air discharge pipe (23) installation site and two numerical value: 55.5 ± 5% and 50.0 ± 5%, and these two numerical value.For example the length of shell of the dust collector (21) and diameter respectively are 180mm and 60mm, and then the length of an end of air discharge pipe (23) and diameter should be designed to respectively about 100mm and 30mm.
Dust catcher of the present invention is rotated motion in order to break off pollutant as shown in Figure 3 on the one hand in shell of the dust collector (21), move to pollutant outlet (24) on the other hand, leaks at shell of the dust collector one side end (21a), forms the adverse current phenomenon.Enlarged shell of the dust collector (21) one side ends (21a) diameter on every side, a sudden change expansion section (25) has been installed again.
Because a sudden change expansion section (25) is installed again, make to shell of the dust collector one side end (21a) even mobile pollutant collides with terminal (21a), also because of colliding with the part of sudden change expansion section (25) protuberance once more, and having weakened impact force, the mobile pollutant of subtend shell of the dust collector one side end (21a) can not produce a very large impact.Therefore, pollutant can not flow in the air discharge pipe (23), has improved dust catching efficiency.
As shown in Figure 3, dust catcher of the present invention is not stopped and leaks by sudden change expansion section (25) in order to prevent the low weight fine particle of some quality, form adverse current at shell of the dust collector one side end (21a), the fine particle phenomenon of dispersing again appears, then on the bump of sudden change expansion section (25), the guider of an outstanding shape is installed again.The guider of outstanding shape and shell of the dust collector are in the parallel installation of length direction.
Consult shown in Figure 3ly, the operation principle of dust catcher of the present invention is as described below:
At first, start the air inhalator (omitting among the figure) of second dust arrester (20) air discharge pipe (23) one sides, contaminated air flows in the inlet tube (12) of first dust arrester (10).At this moment, particle the greater is subjected to the effect of inertia force to continue to move forward in the polluter of inflow, moves to certain distance, and the suffered gravity of particle is deposited on inertia dust collection shell (11) bottom at last greater than inertia force.
Meanwhile, the molecule in air or the pollutant that is not deposited flows into second dust arrester (20) inside by contaminated air suction line (22).At this moment, air is discharged to the outside by air discharge pipe (23); Molecule tangentially is subjected to centrifugal action.Be subjected to the contaminant particle of centrifugal action to continue to rotate, by the pollutant outlet, be deposited on auxiliary dust collecting part (13a) lining in first dust arrester when wherein a part arrives pollutant outlet (24) with circular trace; After a part of in addition and shell of the dust collector one side end (21a) collides, collide with the part of sudden change expansion section (25) protuberance once more, stay on the guider (26),, be deposited on interior auxiliary dust collecting part (13a) lining of first dust arrester by pollutant outlet (24).At last, after rest parts and the collision of shell of the dust collector one side end (21a), again with follow-up pollutant (to the terminal pollutant that moves continuously of shell of the dust collector one side) collision, disturb, weakened active force, rotate in the terminal exterior circumferential of air discharge pipe (23) one sides,, be deposited on auxiliary dust collecting part (13a) lining in first dust arrester at last by pollutant outlet (24).
