Abstract
The utility model discloses a cyclone dust collector, which belongs to the technical field of iron-making and dusting and comprises a cylinder and a dust hopper. The dust hopper is connected with the lower end of the cylinder, an air outlet is arranged on the upper end surface of the cylinder, the middle of the cylinder is provided with an air inlet pipe which enters the interior of the cylinder along the tangential direction of the cylinder wall, and a secondary air inlet pipe is arranged on the wall of the air inlet pipe of the cylinder. The cyclone dust collector is applicable to iron-making technology and dusting system.
Description
Technical field
The utility model relates to a kind of ironmaking cleaner, relates in particular to a kind of cyclone dust collectors.
Background technology
Cyclone dust collectors are dedusters commonly used in the smelter iron-smelting process, its basic principle is that dusty gas tangentially enters cyclone dust collectors at a high speed from air inlet, produce circumnutation along deduster circular cylinder body wall, dust granule is under centrifugal action, thrown to dedusting wall productive set, and move downward and enter ash bucket, regularly to discharge by valve, the gas after dedusting is discharged from last air outlet.
For cyclone dust collectors, its inlet air flow speed is big more, the dust centrifugal force that circumnutation produces in cylindrical shell is big more, dust removing effects is just good more, yet inlet air flow speed is big more, will cause the system pressure loss to become big, cause that dust pelletizing system air-introduced machine air quantity is big, the exhausting negative pressure is big, causes the motor power consumption height.Therefore, for cyclone dust collectors, the setting of inlet air flow speed is a difficult problem.
The utility model content
The purpose of this utility model provides the cyclone dust collectors that a kind of intake is big, inlet air flow speed is big.
The technical solution of the utility model scheme realizes in the following manner: a kind of cyclone dust collectors, comprise circular cylinder body and the ash bucket that is connected with the cylindrical shell lower end, the upper surface of this cylindrical shell is provided with air outlet, cylindrical shell is provided with the air inlet pipe that enters inner barrel along the barrel tangential direction, and the tube wall of the air inlet pipe of described cylindrical shell is provided with secondary air mouth pipe.
Described secondary air mouth pipe is arranged on the side of air inlet pipe near circular cylinder body, and the center line of secondary air mouth pipe and the center line angle of air inlet pipe are 0～20 °.
The center line of secondary air mouth pipe and the center line angle of air inlet pipe are 10 °.
The cyclone dust collectors that the utility model provides are by setting up secondary air mouth pipe, to increase intake on the air inlet pipe of existing cyclone dust collectors, improve the inlet velocity of air-flow, when making the dust circumnutation, produce bigger centrifugal force, be beneficial to dust and thrown to wall, improve dust removing effects.
Description of drawings
Fig. 1 is that the master of the utility model cyclone dust collectors looks schematic diagram.
Fig. 2 is the schematic top plan view of the utility model cyclone dust collectors.
The specific embodiment
As shown in Figure 1 and Figure 2, the embodiment of the cyclone dust collectors that the utility model provides, comprise circular cylinder body 10 and the ash bucket 20 that is connected with circular cylinder body 10 lower ends, the upper surface of this circular cylinder body 10 is provided with air outlet 30, the middle part of circular cylinder body 10 is provided with the air inlet pipe 40 that enters cylindrical shell 10 inside along the barrel tangential direction, and the tube wall of the air inlet pipe 40 of described circular cylinder body 10 is provided with secondary air mouth pipe 50.
Wherein, described secondary air mouth pipe 50 is arranged on the side of air inlet pipe 40 near circular cylinder body 10, the center line angle a of the center line of secondary air mouth pipe 50 and air inlet pipe 40 is 0～20 °, preferably, the center line of secondary air mouth pipe 50 and the center line angle of air inlet pipe 40 are 10 °, make the wind energy that enters from secondary air mouth pipe 50 enough, quicken dust granule and under centrifugal action, thrown to barrel wall, improve dust removing effects along circular cylinder body 10 walls generation circumnutation.
The cyclone dust collectors that the utility model provides, by on the air inlet pipe 40 of existing cyclone dust collectors, setting up secondary air mouth pipe 50, to increase intake, improve the inlet velocity of air-flow, when making the dust circumnutation, produce bigger centrifugal force, be beneficial to dust and thrown to wall, improve dust removing effects.
