Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a kind of embodiment of the utility model, rather than whole realities Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made The every other embodiment obtained, belongs to protection domain of the present utility model.

To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with drawings and the specific embodiments, to this Application is described in further detail.

In the following description, the reference to " one embodiment ", " embodiment ", " example ", " example " etc. shows The embodiment or example so described can include special characteristic, structure, characteristic, property, element or limit, but not each real Applying example or example all necessarily includes special characteristic, structure, characteristic, property, element or limit.In addition, reuse phrase " according to One embodiment of the application " is not necessarily referring to identical embodiment although it is possible to refer to phase be the same as Example.

According to one embodiment of the application there is provided a kind of two-stage dust removal equipment, as shown in figure 1, the two-stage dust removal equipment The primary dust removing device 3 being connected including tower body 1, by connecting pipe 2 with tower body 1 and the two-stage dust removal connected with primary dust removing device 3 Device 4, connecting pipe 2 is twist；In specific implementation, because the thin light specific gravity of dust is easy to be taken out of by tail gas, pass through one Level deduster 3 and secondary ash collector 4 carry out final dusting processing to it, and sufficient processing has been carried out to dust, it is to avoid dust is dirty The situation of dye.

Primary dust removing device 3 includes the cylinder 5 for presenting small lower typhon shape and the dust hopper 6 being arranged under cylinder 5, communicating pipe The one end in road 2 is connected with the exhaust outlet 7 of tower body 1, and the other end is connected with the upper end of cylinder 5；The lower end of dust hopper 6 is provided with discharging opening 8, the center vertical of cylinder 5 is interspersed with an escape pipe 9, and the preferably lower end of escape pipe 9 is located at the middle and lower part of cylinder 5.

In specific implementation, in the spiral entrance primary dust removing device 3 of gas discharged through connecting pipe 2 so that gas Barrel circumference flowing of the body along cylinder 5, and dust is carried out spiral circular motion with certain acceleration by gas urges along barrel； Because cylinder 5 is in up-small and down-big horn-like, its space is become larger, wind speed reduction, and the dust in gas is dropped due to deadweight Into dust hopper 6, and gas enters escape pipe 9 to changed course behind the bottom of cylinder 5, and the gas after dedusting is delivered into secondary ash collector 4 Interior, it is effectively separated dust with gas.

Secondary ash collector 4 includes casing 10 and the adsorption liquid 11 in casing 10, and the outlet side 12 of escape pipe 9 is extended to The bottom of casing 10；The bottom of casing 10 is provided with least one ultrasonic vibrator 13, and the upper end of casing 10 is provided with a blast pipe 14；In tool During body is implemented, the adsorbing powder dust into the gas in secondary ash collector 4 through adsorption liquid 11 by minimal residue in gas, then from row Tracheae 14 is discharged, and is effectively prevented from the situation of dust air inlet；Wherein, the setting of ultrasonic vibrator 13 further increases absorption Adsorption efficiency of the liquid 11 to dust.

According to one embodiment of the application, blast pipe 14 is provided with the first valve 15 and the inspection for detecting dust content A body 17, body 17 and communicating pipe are connected with survey portion 16, the blast pipe 14 between the first valve 15 and test section 16 Road 2 is connected, and body 17 is provided with the second valve 18, and preferably the first valve 15 and the second valve 18 are electrically-controlled valve.

In specific implementation, when test section 16, which is detected, contains dust in the gas by blast pipe 14, second is opened Valve 18, closes the first valve 15, makes to flow out in primary dust removing device 3 again from the gas that secondary ash collector 4 is discharged, again passes by two Secondary dedusting；When test section 16 is not detected by dust, the first valve 15 is opened, the second valve 18 is closed, makes gas from blast pipe 14 discharges；It passes through test section 16, the design effectively of the first valve 15 and the second valve 18 and cooperation, it is ensured that it is complete that dust is handled Entirely, it is to avoid situation of the dust emission into air.

According to one embodiment of the application, the inwall of cylinder 5 is provided with spiral lamination, and both enhanced cylinder 5 bears dynamics, The separative efficiency of dust is improved again.
