The specific embodiment
In order better to understand the object of the utility model complex dust collector, below in conjunction with its background, accompanying drawing and actual condition, its structure and function are described in detail.
The main feature of the utility model complex dust collector is, inertia force precipitator and sack cleaner are combined, the upper end of the inertia force precipitator of leading portion is provided with dusty gas entrance, the lower end of described inertia force precipitator is communicated with the lower end of the sack cleaner of back segment, gas vent after the upper end of described sack cleaner is provided with and purifies.Wherein, the inertia force dedusting area of leading portion can trap coarse granule more than 10-20 μ m, and the bag-type dust district of back segment can trap the dustshot of 0.1-10 μ m, so the utility model can carry out thick dedusting and smart dedusting simultaneously.
Below in conjunction with accompanying drawing, the structure of the utility model specific embodiment is described in detail:
Fig. 1 is the utility model inertia force pocket type complex dust collector structural representation sketch.As shown in Figure 1, described inertia force pocket type complex dust collector includes inertia force precipitator 1 and sack cleaner 4, the air channel of the lower end of described inertia force precipitator 1 is communicated with the inlet plenum 3 of the lower end of sack cleaner 4, and the Purge gas after inertia force precipitator is processed enters sack cleaner through the inlet plenum 3 of described air channel and sack cleaner; The upper end of described inertia force precipitator 1 is provided with dusty gas entrance, and the upper end of described sack cleaner 4 is provided with the exhaust chamber 8 for the discharge of dedusting after-purification gas; Described sack cleaner 4 inside are provided with the cloth bag 5 for filtering gas, and the bottom of described sack cleaner 4 is provided with for storing the ash bucket 10 of the dust that cloth bag 5 falls into.
In described inertia force pocket type complex dust collector, in described inertia force precipitator, baffle plate is housed, the angle α of this baffle plate and horizontal direction is 30-45 °, to strengthen the spin intensity of gas, strengthens coarse grained removal efficiency.
In described inertia force pocket type complex dust collector, the storage ash bucket sidewall of described sack cleaner and the angle β of horizontal direction are greater than 60 °, make deashing easier.
In described inertia force pocket type complex dust collector, described inertia force precipitator and described sack cleaner storage ash bottom are provided with unloading valve 11, for when clearing up the dust of deduster, carry out deashing open to shut to regulate.
In described inertia force pocket type complex dust collector, between the inlet plenum 3 of described sack cleaner and exhaust chamber 8 and sack cleaner body, be provided with valve body, for controlling the break-make situation of air-flow.
Described inertia force pocket type meets in deduster, and the top of described sack cleaner is provided with compressed air spraying pipe 9.
When the air quantity of processing is larger, described inertia force pocket type complex dust collector further may be embodied as and includes two or more fiber bag precipitators, described two or more sack cleaner is set up in parallel, its inlet plenum is all communicated in the air channel that inertia force precipitator is processed rear gas, from described inertia force precipitator Purge gas out, because air quantity is larger, enter respectively two or more sack cleaners.
