Abstract
The utility model provides a cyclone separator with circulation and belongs to the technical field of atmosphere environmental protection and powder handling. A secondary separation cylinder and a spiral device are additionally arranged on positions of an exhaust pipe of an ordinary cyclone separator, airflow inside the exhaust pipe still has high rotary speed, and the airflow is forced to rotate by means of guide action of the spiral device. Secondary separation of dust particles is achieved inside the secondary separation cylinder, an outlet is arranged on the wall of the secondary separation cylinder, the dust particles which are secondarily separated are pumped out by a draught fan, conveyed to an wind inlet of the cyclone separator and then conveyed into the cyclone separator, so that circulation of part of the airflow is formed. The leaked dust particles can be conveyed back to the cyclone separator, separating efficiency is improved, meanwhile, flow velocity in a flow field can be controlled by means of controlling of circulation air quantity.
Description
Technical field
The utility model relates to the high speed rotation that utilizes dusty gas, a kind of separator that dust is separated from air-flow belongs to atmosphere environmental protection and powder handling technical field.
Background technology
The cyclone separator structure that generally uses at present is simple, manufacturing, use, easy to maintenance.It is the rotation that utilizes dust-contained airflow, makes the grit in the air-flow produce certain centrifugal inertial force, and the grit in the rotation to peripolesis, falls to reaching the purpose of gathering dust after running into barrel under the effect of centrifugal inertial force.But the greatest weakness of cyclone separator is poor to the separating power of fine powder at present, thereby has influenced the use of cyclone separator in more occasions.
Summary of the invention
The new a kind of part air-flow of this practicality forms the novel cyclone separator of local circulation.This summary of the invention comprises cone (1); First separation tube (2); An exhaust outlet (3), dust-contained airflow inlet (10), dust-exhausting port (12) and secondary exhaust outlet (6); Between an exhaust outlet (3) and secondary exhaust outlet (6), be provided with secondary separation tube (5), in secondary separation tube (5), be provided with screw (4).This invention comprises that also the barrel of secondary separation tube (5) is provided with circulating current inlet (7), draws the part air-flow in the secondary separation tube (5) thus.Simultaneously locate to be provided with circulating current outlet (11) at dust-contained airflow inlet (10), outside air-flow is introduced thus and is merged with the air-flow of dust-contained airflow inlet (10), is sent to together in the first separation tube (2).This invention is located and is arranged between the circulating current outlet (11) on the dust-contained airflow inlet (10) at the circulating current inlet (7) that is provided with on the barrel of described secondary separation tube (5) and is provided with blower fan (8) and pipeline; And formation path; Part air-flow in the secondary separation tube (5) is delivered to dust-contained airflow inlet (10) locate, mix with the air-flow that gets into from dust-contained airflow inlet (10).This characteristic feature of an invention is after dust-contained airflow gets into first separation tube and cone realization gas solid separation; Still have the dust that part is escaped in the air-flow of an exhaust outlet of entering; The dust of this part escape can be realized gas solid separation again in screw and secondary separation tube; The dust circulating current inlet and the circulating current outlet that are tending towards the edge get into first separation tube and cone again, form the air-flow circulation, can increase substantially the effect of gas solid separation; Reduce the dust of discharging in the gas, reach the effect that efficiently purifies air.
Description of drawings
Fig. 1 structural front view, Fig. 2 structure vertical view are the structural representations that has the cyclone separator of circulation.
Label title among the figure: 1-cone, 2-first separation tube, exhaust outlet of 3-, 4-screw; 5-secondary separation tube, 6-secondary exhaust outlet, 7-circulating current inlet, 8-blower fan; The 9-fan electromotor, 10-dust-contained airflow inlet, the outlet of 11-circulating current, 12-dust-exhausting port.
The specific embodiment
The embodiment of this utility model is: dust-contained airflow gets into from dust-contained airflow inlet (10) and carries out the high speed rotation first separation tube (2) and the cone (1); Grit in the swirling eddy produces the limit motion that becomes under the effect of centrifugal inertial force; Fall from dust-exhausting port (12) after being rebuffed and discharge, accomplish the first separation process of dust.Be provided with secondary separation tube (5) and screw (4) in the top of an exhaust outlet (3); Utilize the discharge air-flow to still have higher rotary speed, utilize the guide effect of spiral again, the air-flow of discharging from an exhaust outlet (3) is further carried out grit separate; Promptly realize secondary separation; One circulating current inlet (7) is arranged at the outer wall place of secondary separation tube (5),, will be deposited on outer dust and the portion gas nearby of secondary separation tube (5) and extract out through the suction of blower fan (8); And deliver to circulating current outlet (11) and locate to converge with the dust-contained airflow of locating from dust-contained airflow inlet (10); Get into first separation tube (2) again, so just realized the circular treatment of part air-flow, the air of cleaning is discharged from secondary exhaust outlet (6).The size of control internal circulating load can be controlled the air velocity of separating flowing field, to reach the purpose that improves dust separation efficient.
