Description

Ultralight fine dust deduster
Affiliated technical field
The utility model relates to a kind of environmental protection cleaner, belongs to the industrial pollution processing technology field, the especially dedusting of dusty gas in the industrial production.
Background technology
At present, industrial processing dusty gas adopts air box impulse bag-type dust remover more, employing be the purge mode of pulse off-line type; So-called off-line ash-clearing is divided into several little case chambers with casing in the deduster (bag chamber) and air-purifying chamber exactly, forms several separate small spaces, and each little case chamber all has a valve (lift valve) to control its ventilation.When valve opening, little case chamber is in running order, and this moment, dusty gas passed through filter bag, dust is isolated in the filter bag outside, and clean gas enters the filter bag inboard, enters air-purifying chamber through the filter bag top, export to deduster through the air channel again, be discharged in the atmosphere, finish the gas cleaning process.When the dust in the filter bag outside reached a certain amount of, resistance increased, and need carry out deashing this moment; During deashing, the valve closing of little case chamber, be in off-line state, at this moment, pulse valve is opened, one high-voltage pulse air-flow pours in the filter bag from the top, pass filter bag to the outside, will blow off attached to the dust in the filter bag outside, these dust drop in the ash bucket by deadweight, discharge by the conveying equipment that the ash bucket bottom is provided with, finish deashing process.
The ultralight fine dust that but some particle is less, proportion is lighter can not sink by deadweight, and the space between the bag chamber of floating all the time can not be deposited in the ash bucket with air-flow.General sack cleaner is after deashing finishes, when the lift valve of little case chamber is opened, because the swabbing action of blower fan, these ultralight fine dusts that float are called " secondary adheres to ", when this " secondary adheres to " reaches a certain amount of again immediately attached to the outside of filter bag, filter bag is stopped up, resistance increases, and causes the deduster cisco unity malfunction, the existing defective of present common air box impulse bag-type dust remover that Here it is.
The utility model content
In order to overcome the deficiency of existing deduster, the utility model provides a kind of and eliminates ultralight fine dust formed " secondary adheres to " phenomenon, and can remove the deduster of ultralight fine dust.
The technical scheme that its technical problem that solves the utility model adopts is: ultralight fine dust deduster is made up of main box, air inlet, air outlet, air channel dividing plate, ash bucket and air valve, main box is made up of 3~20 little case chambers, each little case chamber is made up of upper box, 32~128 filter bags, air-purifying chamber, lift valve, pulse valves, is equipped with a dust locking device in the ash bucket of the bottom of each little case chamber.
Dust locking device is a bucket shape, is made up of internal portioning layer, spring gate, weight valve.Internal portioning layer is obliquity, in the internal portioning layer bottom spring gate is installed, and the air inlet in little case chamber is equipped with the weight gate; When two closing gates, little case chamber forms a confined space, and dust is enclosed in this space.
The beneficial effects of the utility model are, use this deduster to avoid the generation of " secondary adheres to " phenomenon, have reduced the dedusting resistance, and efficiency of dust collection can reach 99.99%, and blackness of exhaustion is 0 grade of Lin Geman, and dust emission concentration is less than 50mg/Nm 3Prolong the work period of deduster, improved operating efficiency.When the utility model was used for the coal-burning boiler dedusting, effect was very obvious, can improve the operating efficiency of boiler greatly.And during with common pocket type pulsed dust collector dedusting, because the carbon powder dust particle is very little, proportion is very light, often stops up filter bag, needs blowing out to carry out artificial deashing, has had a strong impact on the normal operation of boiler.

Fig. 2 is the medium and small case of a utility model chamber working state figure, and arrow is the dust flow direction among the figure;
Fig. 3 is the utility model deduster schematic front view:
Fig. 4 is the utility model deduster diagrammatic side view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Ultralight fine dust deduster is made up of main box, air inlet 10, air outlet 11, air channel dividing plate 12, ash bucket 6 and air valve 8, main box is made up of 6 little case chambers 14, each little case chamber 14 is made up of upper box 13,32 filter bags 7, air-purifying chamber 5, lift valve 1, pulse valves 9, is equipped with a dust locking device in the ash bucket 6 of the bottom of each little case chamber 4.
Dust locking device is a bucket shape, is made up of internal portioning layer 4, spring gate 3, weight gate 2.Internal portioning layer 4 bottoms are equipped with spring gate 3, at the air inlet place of little case chamber 14 weight gate 2 are installed; The angle of inclination of internal portioning layer 4 is parallel with ash bucket 6 angles of inclination; Lift valve 1 is installed in the top of air-purifying chamber 5, and pulse valve 9 is installed in the top of air-purifying chamber 5.
As shown in Figure 1, when 14 pulse dust cleanings of little case chamber, owing to closed lift valve 1, weight gate 2 is closed at this moment, pulse valve 9 winding-up air pulses rush at the outside by the inboard of filter bag 7, dust part under clear downwards by spring gate 3, flows to the outer space of ash bucket 6 with air pulse, also leaves the small part dust and is suspended in the casing; At this moment, pulse valve 9 air pulse of jetting is once more taken away the outer space that the part dust enters ash bucket 6 again; Spring gate 3 is closed automatically, and the dust that sweeps away is locked in the outer space of ash bucket 6, and this moment, deashing finished.
Then as shown in Figure 2, lift valve 1 is opened, the weight gate 2 of little case chamber 14 air inlets is opened under the effect of blower fan, make little case chamber 14 in running order, at this moment only surplus have low amounts of dust to form " secondary adheres to ", and most of dust is isolated in the outer space of ash bucket 6, by air valve 8, be transported to the deduster external treatment, make deduster energy operate as normal.
In conjunction with the accompanying drawings the specific embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
