The drying technology is used for treating the oily sludge and is widely applied to the petrochemical industry. In the oil-containing sludge drying system in the prior art, a drying device for oil-containing sludge generally uses a large amount of circulating air for drying to dry the oil-containing sludge. During the drying process of the oil-containing sludge, part of dust is inevitably carried out from the oil-containing sludge into the circulating air for drying. In order to remove dust from the drying circulation air discharged from the drying device, a dust removing device is generally connected to an air outlet of the drying device to reduce the dust content in the drying circulation air discharged from the drying device.

An embodiment of the present invention provides a dust removing apparatus, which is shown in fig. 1 and 2, and includes: the device comprises a first cylinder 1, a first cone 2, a second cylinder 3, a second cone 4, an ash hopper 5 and an ash discharge valve 6; the first cylinder 1, the first cone 2, the second cylinder 3, the second cone 4, the ash bucket 5 and the ash discharge valve 6 are connected in sequence; the first cylinder 1 is provided with an air inlet 101 and an air outlet 102, which are respectively used for inlet and outlet of circulating air for drying.
In the use process of the dust removing equipment, the air inlet 101 leads to the circulating air for drying, and because the circulating air for drying contains dust, the cyclone separation effect is increased through the structure of two sections of cylinders and two sections of cones formed by the first cylinder 1, the first cone 2, the second cylinder 3 and the second cone 4 from top to bottom, and the separation effect is stronger than that of a one-section structure. Dust in the drying air for circulation is more easily separated and falls into the dust hopper 5; the dust in the dust hopper 5 can be discharged out of the dust removing equipment by opening the dust discharging valve 6; meanwhile, the circulating drying air after dust removal is discharged through an air outlet on the first cylinder 1.
According to the dust removing device provided by the utility model, the two-section cylinder body formed by the first cylinder body 1, the first cone body 2, the second cylinder body 3 and the second cone body 4 and the two-section cone body structure from top to bottom enable the circulating drying air entering the dust removing device to rotate in the two-stage tank body formed by the first cylinder body 1, the first cone body 2 and the second cylinder body 3 and the second cone body 4 in an accelerated manner to generate centrifugal force, so that the rotating dust is separated from the circulating drying air, and the circulating drying air after dust separation is carried out on the first cylinder body 1 and the first cone body 2 is subjected to finer dust separation through the second cylinder body 3 and the second cone body 4, so that the dust separation is more thorough, and the dust removing effect is ensured.
The dust removing equipment provided by the utility model can effectively remove oil small-particle powder (such as scum) in the dust removing process, avoid the continuous accumulation of dust formed by the small-particle powder in circulating air for drying, and prevent the scaling of the air dust in the drying equipment and the dust removing equipment; moreover, the continuous accumulation of small particle powder in the circulating air for drying is avoided, and the safety risk to an oily sludge drying system is avoided, so that the continuity and the safety of oily sludge drying are ensured, and the working efficiency of oily sludge drying is improved.

In one embodiment, the air inlet 101 is disposed on one side of the first cylinder 1, and the air outlet 102 is disposed on the top end of the first cylinder 1.
In one embodiment, the dust removing apparatus further includes: a discharging cloth bag 7; the discharging cloth bag 7 is connected with the ash discharging valve 6. When the ash discharge valve 6 is opened, the dust in the ash hopper 5 is collected into the discharge cloth bag 7 through the ash discharge port 14.
In one embodiment, a steam outer coil 8 is arranged outside the dust removing device, in the use process, heated steam is introduced into the steam outer coil through a heating steam inlet 9 to heat the drying circulating air entering the dust removing device, and the steam after heat exchange is discharged out of the steam outer coil through a heating steam outlet 10.
When the dust removing equipment is used for removing dust from the circulating drying air discharged from the drying equipment, the circulating drying air discharged from the drying equipment contains a large amount of water vapor evaporated from oil-containing sludge, and the heated water vapor is introduced into the steam outer coil pipe to heat the circulating air for drying, so that the water vapor in the circulating drying air is prevented from being condensed into water drops in the dust removing equipment to cause dust condensation.
In one embodiment, the ash hopper 5 may be provided with a first level gauge port 12 and a second level gauge port 13, a high level gauge L1 (not shown in the figure) is provided at the first level gauge port 12, and a low level gauge L2 (not shown in the figure) is provided at the second level gauge port 13;
the high level indicator L1 interlocked starting ash discharging valve 6, and the low level indicator L2 interlocked closing ash discharging valve 6.
The dust removing equipment provided by the utility model realizes automatic ash discharge by utilizing the switch of the high and low material level interlocking ash discharge valve 6. That is, when dust is accumulated to the position of the high level gauge L1, the high level gauge L1 is interlockingly actuated to open the dust discharge valve 6, thereby discharging the accumulated dust; when the upper surface of the accumulated dust falls to the low level L2 position, the low level L2 interlockingly closes the dust discharge valve 6. Because there is the dust of take the altitude in 5 bottoms of ash bucket, realized the self sealss of ash bucket 5, help realizing the balance of system pressure, oxygen in the air reveals the entering when avoiding exhausting, causes the safety risk of system.

The nitrogen is introduced through the nitrogen back flushing port 11, so that dust in the ash hopper 5 cannot be attached to the inner wall of the ash hopper 5 and cannot be hardened, and the effect of preventing materials from bridging is achieved. In the embodiment of the utility model, the ash hopper 5 can be provided with a plurality of nitrogen back-blowing openings 11. When in use, the nitrogen blowback port 11 can continuously introduce nitrogen, or introduce nitrogen at preset time intervals, for example, 30s, 60s or 180s blow nitrogen once into the ash hopper 5 through the nitrogen blowback port 11.
In one embodiment, the dust removing apparatus may be made of S30408 steel. In the embodiment of the utility model, because the circulating air for drying entering the dust removing equipment contains oil which is volatilized to easily form small-particle powder (such as scum) and a large amount of water vapor, the dust removing equipment can be made of S30408 steel in order to prevent the oil and the gas from corroding the dust removing equipment.
