The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, so that those skilled in the art can better understand the present invention also, can be implemented, but illustrated embodiment is not as a limitation of the invention.
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 the external feed stream system, is provided with the wind deflector 21 of the steering current direction of motion in expansion chamber 1, the outlet of described expansion chamber 1 and postorder equipment connection.
Expansion chamber 1 is as the elementary device that gathers dust in advance 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, can also make dust carry out preliminary sedimentation, ash-laden gas after preliminary sedimentation enters in postorder equipment 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, makes the dust air-flow enter the rear speed of expansion chamber 1 and reduces suddenly, can make some larger particles dust separate from air-flow.
In order to guarantee all can to play the effect of guiding, sedimentation to dust-contained airflow, described wind deflector 21 is obliquely installed and runs through whole expansion chamber 1 along the air-flow traffic direction, 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.
Wire length between the top that the length of wind deflector 21 is air inlet 3 herein and the rear wall of expansion chamber 1, concrete numerical value is depending on the structure of expansion chamber 1, and only need to covering the width of air inlet 3, the width of wind deflector 21 gets final product, not only effectively play the effect of water conservancy diversion and sedimentation, can also save material, save cost.
In order further to obtain better effect, 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 common U-shaped wind guide tank 2 structures that form of side plate 22, be provided with arc 23 in described wind guide tank 2, an 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 a plurality of and evenly spaced, and be provided with hole on the wind deflector 21 between adjacent arc 23, gas through collision, reflection is discharged to upper space by hole, described arc 23 and a similar wave wing shape of wind deflector 21 common formations, the angle of the tangent line of described arc 23 and wind deflector 21 is 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 type 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 the concentrated outside that is 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 is collected the dust of sedimentation fully.
As shown in Figure 4, dusty gas enters behind the first grade subsides chamber under U-shaped wind guide tank 2 effects, is forced to after must be from wind guide tank 2 two side direction upwards flowing out, and reaches air velocity and reduces and evenly flow into the purpose in expansion chamber 1.
The present invention, in concrete implementation process, provides the dust settling technology three times:
Gas handling system as shown in the figure, after ash-laden gas enters expansion chamber 1, through three sedimentations, enter in the precipitation apparatus of postorder, dust-contained airflow enters into the interior speed of expansion chamber 1 can be reduced, big dust particle, through after three sedimentation techniques, can fall in the ash bucket 4 of expansion chamber 1 fully.
Sedimentation techniques for the first time:
After dusty gas enters expansion chamber 1, the air inlet 3 of expansion chamber 1 is diffused, according to the aerodynamic principle high velocity air enter Speed Reduction after expanded channnel, pressure strengthens, after the high velocity air Speed Reduction, in air-flow, dust is because air velocity reduces suddenly, some larger particles dust are separated under flow velocity and pressure-acting from air-flow, thereby naturally drop into, reach dirt for the first time in the ash bucket of expansion chamber 1 and fall.
Sedimentation techniques for the second time:
After dusty gas enters expansion chamber 1, need be after the U-shaped wind guide tank 2 of one 40 ° wave wing types, just can enter in the casing of expansion chamber 1, enter the dust-contained airflow of expansion chamber 1, because arc 23 has changed the flow direction of air-flow, force air-flow to flow downward along arc 23, change due to the air current flow direction, the flowing velocity of air-flow is obstructed and is caused dust and arc 23 in flue gas and bumps, thereby reach the purpose that reduces for the second time air-flow velocity, some larger dust granules in air-flow are changed and under the shock of arc 23 rubs at flow direction, larger dust granules is separated again from air-flow, fall in expansion chamber 1 ash bucket 4, reach sedimentation for the second time.
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, form shock with a sidewall paneling of expansion chamber 1 ash bucket 4 under this angle effect, after one sidewall paneling of airflow strikes ash bucket 4, airflow direction changes fully, be tilted to the anti-U-shaped wind guide tank 2 that enters in the effect of impact downstream, form to clash into follow-up inflow air-flow and make air-flow generation sinuous flow, gas flow rate reduces fully, larger particles dust in dusty gas, be forced in expansion chamber 1 ash bucket 4 sedimentation and then reached sedimentation for the third time under the effect of sinuous flow.
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 at aspects such as treatment of urban garbage, garbage powers, have more the irreplaceable advantage of other technologies.
The above embodiment is only the preferred embodiment for absolutely proving that the present invention lifts, and protection scope of the present invention is not limited to this.Being equal to that those skilled in the art do on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
