Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, can better understand the present invention and can be implemented, but illustrated embodiment is not as a limitation of the invention to make those skilled in the art.
As shown in Figure 1 to Figure 3, be the expansion chamber structure chart of deduster of the present invention, the air inlet 3 of described expansion chamber 1 is connected with external feed stream system, and be provided with the wind deflector 21 guiding air motion direction in expansion chamber 1, the outlet of described expansion chamber 1 is connected with following apparatus.
Expansion chamber 1 is as the elementary pre-dust arrester installation of duster system, ash-laden gas enters into the inside of expansion chamber 1 by air inlet 3, wind deflector 21 in expansion chamber 1: there is the guide effect to ash-laden gas, dust can also be made to carry out preliminary sedimentation, ash-laden gas after preliminary sedimentation enters in following apparatus through gas outlet, carries out next step dust settling.
The air inlet 2 of described expansion chamber is flaring type entrance, utilizes the setting of flaring type air inlet, and after making dust air-flow enter expansion chamber 1, speed reduces suddenly, and some larger particles dust can be made to separate from air-flow.
In order to ensure the effect all can playing guiding, sedimentation to dust-contained airflow, described wind deflector 21 is obliquely installed along air-flow traffic direction and runs through whole expansion chamber 1, in the present embodiment, one end of wind deflector 21 is connected with the top of air inlet 3, and the other end of described wind deflector 21 is connected with the rear wall of expansion chamber 1.
The length of wind deflector 21 is the wire length between the top of air inlet 3 and the rear wall of expansion chamber 1 herein, concrete numerical value is depending on the structure of expansion chamber 1, and the width of wind deflector 21 only needs the width covering air inlet 3, not only effectively play the effect of water conservancy diversion and sedimentation, can also material be saved, save cost.
In order to obtain better effect further, the bottom of described wind deflector 21 is provided with arc 23, in order to make wind-guiding, effect of settling better, the both sides of described wind deflector 21 are respectively arranged with a side plate 22, described wind deflector 21 and two side plates 22 form U-shaped wind guide tank 2 structure jointly, be provided with arc 23 in described wind guide tank 2, one end of described arc 23 is connected with wind deflector 21, and two sides of described arc 23 are connected with two side plates 22 respectively.
Described arc 23 is multiple and uniform intervals is arranged, and the wind deflector 21 between adjacent arc 23 is provided with hole, gas through collision, reflection is discharged to upper space by hole, described arc 23 and wind deflector 21 form a similar wave wing shape jointly, the tangent line of described arc 23 and the angle of wind deflector 21 are 30 ° to 60 °, in the present embodiment, for making wind effect better, the tangent line of described arc and the angle of wind deflector are 40 °, and described arc and wind guide tank form the U-shaped wind guide tank 2 of wave wing jointly.
The bottom of described expansion chamber 1 is provided with ash bucket 4, ash bucket 4 is for collecting the dust of sedimentation, and concentrate the outside being discharged to deduster, the number of described ash bucket 4 can be one or more, and the upper open area sum of described ash bucket 4 must cover the area of whole described expansion chamber 1 bottom surface, and guarantee collects the dust of sedimentation completely.
As shown in Figure 4, dusty gas to enter behind first grade subsides room under U-shaped wind guide tank 2 acts on, be forced to must from wind guide tank 2 two side direction after upwards flowing out, reach air velocity and reduce the object evenly flowed in expansion chamber 1.
The present invention, in concrete implementation process, provides three dust settling technology:
Gas handling system as shown in the figure, after ash-laden gas enters expansion chamber 1, enter in the precipitation apparatus of postorder through three sedimentations, dust-contained airflow enters into speed in expansion chamber 1 can be reduced, big dust particle, after three sedimentation techniques, can fall in the ash bucket 4 of expansion chamber 1 completely.
Sedimentation techniques for the first time:
After dusty gas enters expansion chamber 1, the air inlet 3 of expansion chamber 1 is diffused, speed reduction after entering expanded channnel according to aerodynamic principle high velocity air, pressure strengthen, after high velocity air speed reduces, in air-flow, dust reduces suddenly due to air velocity, some larger particles dust are separated under flow velocity and pressure effect from air-flow, reach first time dirt and fall in the ash bucket naturally dropping into expansion chamber 1.
Second time sedimentation techniques:
After dusty gas enters expansion chamber 1, need after the U-shaped wind guide tank 2 of 40 ° of wave wing, just can enter in the casing of expansion chamber 1, enter the dust-contained airflow of expansion chamber 1, because arc 23 changes the flow direction of air-flow, force air-flow arcuately plate 23 flow downward, due to the change in air current flow direction, the flowing velocity of air-flow is obstructed and is caused dust and arc 23 in flue gas and collides, thus reach the object that second time reduces air-flow velocity, make some larger dust granules in air-flow under flow direction changes and the shock of arc 23 rubs, larger dust granules is separated again from air-flow, fall in expansion chamber 1 ash bucket 4, reach second time sedimentation.
Sedimentation techniques for the third time:
After dusty gas enters expansion chamber 1, the U-shaped wind guide tank 2 that Open Side Down has a 6-8 ° of angle with the plane of ash bucket 4, enter the dust-contained airflow of U-shaped wind guide tank 2, formed with a sidewall paneling of expansion chamber 1 ash bucket 4 under this angle effect and clash into, after one sidewall paneling of airflow strikes ash bucket 4, airflow direction changes completely, effect of impact downstream tilt upward counter enter U-shaped wind guide tank 2, form shock with follow-up inflow air-flow and make air-flow generation sinuous flow, gas flow rate reduces completely, larger particles dust in dusty gas, under the effect of sinuous flow, to be forced in expansion chamber 1 ash bucket 4 sedimentation and then to be reached third time sedimentation.
Purification techniques of the present invention not only in coal-burning power plant, steel industry, Petroleum Industry, cement, the pollution control of all types of industries civil boiler have a wide range of applications, especially, in treatment of urban garbage, garbage power etc., the irreplaceable advantage of other technologies is had more.
The above embodiment is only that protection scope of the present invention is not limited thereto in order to absolutely prove the preferred embodiment that the present invention lifts.The equivalent alternative or conversion that those skilled in the art do on basis of the present invention, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
