Abstract
The utility model relates to a dust hopper which mainly comprises a dust hopper body. An air inlet is arranged on the dust hopper body which is internally provided with a plurality of spoilers, the spoilers are mutually staggered and distributed in a wave shape. The utility model has the advantages that the scouring force of flue gas for the inner wall of the dust hopper is reduced, and large grained bug dust is filtered so as to decrease the filter load of a filter bag, thereby the service life of a wainscot of the dust hopper is further prolonged.
Description
Technical field
The utility model relates to the bag-type dust collecting equipment of handling the flue gas that coal-burning boiler produced, is specifically related to a kind of ash bucket that is applied to this equipment.
Background technology
In the bag-type dust collecting equipment of handling the fuel boiler flue gas, ash bucket is between middle casing filter chamber and air intake three-way pipe, and middle casing filter chamber is positioned at the top of ash bucket, and the air intake three-way pipe connects the air inlet of ash bucket.The main effect of ash bucket is that flue gas is carried out the elementary dedusting of inertia and the air-flow that gathers is disperseed to spread, and makes flue gas behind the casing filter chamber dust removing effects preferably can be arranged in entering.
Generally speaking, flue gas is entered by the air intake three-way pipe in the process of each ash bucket, and its air-flow is in laminar condition through the effect of air intake three-way flow guide plate.Ash-laden gas is about about 7～10m/s through speed herein, so high flue gas stream is being carried a large amount of dust-laden particles (material dust that especially has abrasive properties, as Iron Ore Powder etc.), consumingly ash bucket air intake opposite inwall is ground to hack and wash away, cause outer wall worn out by dust granule in a short period of time.Meanwhile, part big dust particle in the flue dust is because action of inertia, with ash bucket wallboard generation elastic collision, after the bounce-back vertically upward, the bottom of direct collision filter bag, especially at the bottom of the filter bag bag with the very near situation of air inlet distance under, be worn through in a short period of time at the bottom of causing the filter bag bag.
The utility model content
At the problems referred to above, the utility model provides a kind of can become turbulent flow with laminar flow, reduces flue gas to wallboard being washed away the ash bucket of dynamics.
For achieving the above object, the technical solution of the utility model is to adopt:
Described ash bucket comprises: the ash bucket body, on the ash bucket body, be provided with air inlet, and it is characterized in that be provided with some spoilers in the ash bucket body, described spoiler staggers mutually, undulate distributes.
Wherein, described spoiler is located on the air intake airflow direction of air inlet.
Wherein, described spoiler is with respect to vertical with the air intake airflow direction of the air inlet downward-sloping certain angle of air inlet that faces.
Wherein, described angle of inclination is between 20 degree～30 degree.
Wherein, the gap between the described spoiler is between 200mm～300mm.
Wherein, spoiler adopts wear-resisting steel plate to make.
Wherein, the thickness of spoiler is greater than 5mm.
Advantage of the present utility model and beneficial effect are, use ash bucket of the present utility model, can make flue gas become turbulent flow from laminar flow, reduce the wash away dynamics of flue gas to the ash bucket inside panel.Simultaneously, big dust particle after the generation elastic collision, enters the ash bucket bottom under the effect of spoiler, and like this, this spoiler had both carried out preliminary filtration to flue dust, had reduced the filtration load of filter bag, had further increased the service life of ash bucket wallboard again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, ash bucket body; 2, air inlet; 3, spoiler.
The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, ash bucket described in the utility model mainly comprises: ash bucket body 1 is provided with air inlet 2 on ash bucket body 1; In ash bucket body 1 inside, multi-disc spoiler 3 is set on the air intake airflow direction, be example with five spoilers 3 in the present embodiment.Above-mentioned each spoiler 3 staggers up and down mutually, is wavy distribution.Spoiler 3 adopts wear-resisting steel plate to make, and thickness is greater than 5mm.Gap strictness between spoiler 3 and the spoiler 3 is controlled at 200mm to (as if excesssive gap, will losing the effect of choked flow between the 300mm by Hydrodynamics Theory and requirement; The gap is too little, can increase the running resistance of deduster, and is simultaneously, also uneconomical).Spoiler 3 is with respect to vertical with the air intake airflow direction of the air inlet downward-sloping certain angle of air inlet that faces, described angle is between 20 degree and 30 degree, guarantee that inlet air flow is through spoiler the time, laminar flow becomes turbulent flow gradually, reduce the wash away dynamics of wall dust to wallboard, simultaneously, big dust particle is under the effect of spoiler, after the elastic collision, enter the ash bucket bottom.Like this, spoiler has promptly carried out preliminary filtration to flue dust, has reduced the filtration load of filter bag, has further increased the service life of ash bucket wallboard again.
Operation principle of the present utility model is: after flue gas enters the ash bucket body by air inlet, can run into the spoiler that is arranged on the ash bucket body interior, make flue gas become turbulent condition from laminar flow, reduce the wash away dynamics of flue gas to the ash bucket inner body wall, simultaneously, because of spoiler and inlet air flow direction are arranged to certain angle, big dust particle in the flue gas is under the effect of spoiler, after elastic collision takes place, enter the ash bucket bottom, spoiler had both carried out preliminary filtration to flue dust like this, had reduced the filtration load of filter bag, had further increased the service life of ash bucket wallboard again.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, but these improvement and modification also should be considered as protection domain of the present utility model.
