Preferable, said first blower fan next-door neighbour is near the air intake of said air outlet.
Be the variation of adaptation vehicle flowrate to the generation of tunnel air-flow, thereby reach best ventilating dust-removing effect, the head end of said air chimney is a blind end; The circumference of said air chimney is provided with at least one breach, and each breach constitutes each said air intake; Said air chimney is positioned at each said air intake place the arc air door is set; Be welded with the regulating handle that stretches out on the said air chimney on the said arc air door; Said air chimney is along circumferentially being provided with the regulating tank that is used to hold said regulating handle circular motion.
For ease of the adjusting of air door, said arc air door is provided with first ball grooves near said air chimney one side; The corresponding said first ball grooves place of said air chimney is provided with second ball grooves; Be provided with ball in said first ball grooves and second ball grooves.
Preferable, be arranged at intervals with three air intakes on the said air chimney, wherein an air intake is positioned at the head end of air chimney; The distance of each air intake equates.
For improving ventilating dust-removing effect, said air outlet place is provided with second blower fan.
For reducing noise, corresponding said first blower fan of the inwall of said air chimney and the second blower fan place are provided with beam respectively; Said first blower fan and second blower fan all are fixedly connected with fan supporter; Said fan supporter is fixed on the said beam.
Preferable, said air chimney is formed by end to end four sections, and adjacent two sections are perpendicular to one another.
Preferable, said first blower fan and second blower fan are axial fan;
The beneficial effect of the utility model is: the utility model is simple in structure, and is easily manufactured, and cost is low, noise is little.
Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the working state schematic representation of the utility model one specific embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As depicted in figs. 1 and 2, a kind of tunnel ventilation dust arrester comprises that by four sections end to end air chimneys of forming 1 adjacent two sections of air chimney are perpendicular to one another.Head end 1a on the air chimney 1 is a blind end, and tail end 1b is an air outlet 2.Be provided with first blower fan 4 in the air chimney 1, air outlet 2 places are provided with second blower fan, 11, the first blower fans 4 and second blower fan 11 is axial fan.
In other specific embodiment, between first blower fan 4 and second blower fan 11, also can set up more blower fan, to reach better technique effect.
Be positioned at the upstream end of first blower fan 4, be disposed with three breach on the circumference of airduct 1 vertically, three breach constitute three air intakes 3; The spacing of each air intake is 70m; Wherein, an air intake is positioned at the head end 1a of air chimney 1, and an air intake is close to first blower fan 4.
In other specific embodiment, the air intake of other quantity also can be set, to reach essentially identical technique effect, the spacing of each air intake is that 50～100m is preferable.
Corresponding first blower fan 4 of the inwall of air chimney 1 and second blower fan, 11 places are provided with beam 12, the first blower fans 4 respectively and second blower fan 11 all is fixedly connected with fan supporter 13, fan supporter 13 is fixed on the beam 12.
As shown in Figure 3, the tunnel ventilation dust arrester is installed in the top in tunnel 15 through mast-up 14, and wherein the head end 1a of air chimney is positioned at the middle part in tunnel 15.Vertical with first section of air chimney 1 second section, and the 3rd section and the 4th section of being connected with second section all stretches out outside the outlet in tunnel 15.Tail end 1b at air chimney is provided with dedusting pond 16, and the tail end 1b of air chimney and the liquid level in dedusting pond 16 are vertical substantially, and is positioned under the liquid level in dedusting pond 16 5～10 centimetres.
During the work of tunnel ventilation dust arrester; Through regulating arc air door 5; Open near the air intake 3 of air chimney 1 head end 1a, all the other two air intakes are in closed condition, start first blower fan 4 and second blower fan 11; Be with the dirt air-flow to be inhaled in the air chimney 1 from air intake 3 this moment, and flow to air outlet 2 places.Because air outlet 2 is under the liquid level, under the brute force that second blower fan 11 is produced, band dirt air-flow is blown in the dedusting pond 16, and therefore, dust is absorbed in dedusting pond 16.In this course, because the effect of first blower fan 4 and second blower fan 11, the air pressure in the air chimney 1 is less than the outer air pressure of air chimney, so air sent in the air chimney 1 endlessly, and in the inflow of the fresh air outside the tunnel tunnel.
When the flow motor in the tunnel 15 is big, can accelerate the inflow velocity of tunnel outer air, can open one of two other air door this moment according to vehicle flowrate, and close the air intake 3 near the air chimney head end, to reach best ventilating dust-removing effect.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
