Abstract
The utility model discloses an auxiliary blowing device for discharging dust in a dust remover, so as to facilitate the downward discharging of dust in a tapered chamber. The auxiliary blowing device comprises a longitudinal blowing device arranged at an outlet in the bottom of the tapered chamber in the lower part of the dust remover; the longitudinal blowing device comprises a T-shaped shower nozzle positioned in the outlet and an air inlet connector connected to one side wall of the outlet; the T-shaped spray nozzle comprises an air inlet pipe and a spray head positioned at one end part of the air inlet pipe; the air inlet pipe is connected with the air inlet connector; the spray head is provided with a first nozzle and a second nozzle; the first nozzle points to the upper part of the outlet; the second nozzle points to the upper part of the outlet. In dust discharge, high pressure nitrogen is filled in the outlet in the bottom of the tapered chamber through the longitudinal blowing device, and is sprayed out up and down from the first nozzle and the second nozzle on the spray head respectively, dust gathered in the outlet in the bottom of the tapered chamber is stirred and damaged, the outlet is sufficiently dredged, dust blockage is prevented, and dust falling is urged.
Description
Technical field
The application relates to the auxiliary blowing device of a kind of remover ash discharge dust.
Background technology
Generally speaking, the bottom of all kinds of dedusters (comprising gravitational precipitator, cyclone dust collectors, electrostatic precipitator and pneumatic filter) that use in industrial production is all a taper chamber, the dust being got off by gas solid separation in deduster is in the indoor progressively sedimentation of this conical cavity, and then is discharged into ash can by the ash-valve of taper cavity bottom.Sometimes, be deposited on the dust mobility poor (for example very light weight and the coal ash of easily assembling) in taper chamber, be deposited in taper chamber and be difficult for discharging downwards, thereby normal use of deduster caused to certain influence.
Utility model content
The application aims to provide a kind of auxiliary blowing device of remover ash discharge dust that contributes to the downward ash discharge of taper chamber.
The application's the auxiliary blowing device of remover ash discharge dust, be included in longitudinal blowing device of the outlet at bottom place setting of deduster lower taper chamber, this longitudinal blowing device comprises and is positioned at the T shape shower nozzle of this outlet inside and is connected to the inlet suction port on this outlet sidewall, described T shape shower nozzle is made up of air inlet pipe and the jet thrust that is positioned at air inlet pipe end, air inlet pipe is connected with inlet suction port, and jet thrust has the first nozzle that points to outlet top and the second nozzle that points to outlet top.
When ash discharge, in the outlet at bottom of taper chamber, inject high pressure nitrogen by longitudinal blowing device, first nozzle and the second nozzle respectively up and down ejection of high pressure nitrogen on jet thrust, the dust gathering in taper chamber outlet at bottom is stirred, destroyed, outlet is dredged fully, prevent that dust from stopping up, impel dust to fall.
Below in conjunction with the drawings and specific embodiments, the present invention is described further.The aspect that the present invention is additional and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Brief description of the drawings
Fig. 1 is the structural representation of the application's remover ash discharge dust servicing unit.
Fig. 2 is that the application's remover ash discharge dust servicing unit is at the structural representation of overlooking in direction.
Fig. 3 is the enlarged diagram of longitudinal blowing device in the application's remover ash discharge dust servicing unit.
Detailed description of the invention
As shown in Figure 1, 2, deduster lower taper chamber 1 overcoat has a horizontally disposed endless tube 2, this endless tube 2 is connected with intake interface 4, on endless tube 2, circumferentially interval is furnished with four air inlet scavenging conduits 3, and these four air inlet scavenging conduits 3 stretch out and pass into taper chamber 1 with direction tangent and on the lower side from endless tube 2 inner sides respectively.Wherein, for ensureing that air inlet scavenging conduit 3 purges effect preferably, the center line of each air inlet scavenging conduit 3 and the angle of horizontal plane are preferably 5-20 °, and in present embodiment, the center line of these four air inlet scavenging conduits 3 and the angle of horizontal plane are specially 10 °.
As shown in Figure 1, the outlet at bottom place of taper chamber 1 is also provided with a longitudinal blowing device, this longitudinal blowing device comprises that the T shape shower nozzle 5(that is arranged in this outlet inside illustrates in the mode of broken section at Fig. 1) and be connected to the inlet suction port 6 on this outlet sidewall, as Fig. 3, described T shape shower nozzle 5 is made up of air inlet pipe 502 and the jet thrust 501 that is positioned at air inlet pipe 502 ends, air inlet pipe 502 is connected with inlet suction port 6, and jet thrust 5 has the first nozzle 501A that points to outlet top and the second nozzle 501B that points to outlet top.In addition,, as Fig. 1, jet thrust 501 is preferably positioned at the center of taper chamber 1 outlet at bottom.
Above-mentioned intake interface 4, endless tube 2 and four air inlet scavenging conduits 3 form blow device, when ash discharge, in the taper chamber 1 of deduster bottom, inject high pressure nitrogen by this device, high pressure nitrogen acts on the cut mode of deflection below the dust adhering on taper chamber 1 inwall, make dust loosening, thereby promote the downward ash discharge of dust.Due to high pressure nitrogen tangential and motion (center line of air inlet scavenging conduit 3 and horizontal plane have 10 ° of angles) on the lower side on the inwall of taper chamber 1, can form the air-flow being rotated down, make dust on taper chamber 1 inwall by clean removing.
Match with above-mentioned purging, in the outlet at bottom of taper chamber 1, inject high pressure nitrogen by longitudinal blowing device simultaneously, first nozzle 501A and the second nozzle 501B respectively up and down ejection of high pressure nitrogen on jet thrust 5, the dust gathering in taper chamber 1 outlet at bottom is stirred, destroyed, outlet is dredged fully, prevent that dust from stopping up, impel dust to fall.By by above-mentioned purging and the longitudinally combination of injection technology, greatly improve the ashing capacity of taper chamber 1.
Claims (2)
1. the auxiliary blowing device of remover ash discharge dust, it is characterized in that: the longitudinal blowing device that is included in the outlet at bottom place setting of deduster lower taper chamber (1), this longitudinal blowing device comprises and is positioned at the T shape shower nozzle (5) of this outlet inside and is connected to the inlet suction port (6) on this outlet sidewall, described T shape shower nozzle (5) by air inlet pipe (502) and be positioned at air inlet pipe (502) end jet thrust (501) form, air inlet pipe (502) is connected with inlet suction port (6), jet thrust (5) has the first nozzle (501A) that points to outlet top and the second nozzle (501B) that points to outlet top.
