Description
Technical field
The utility model belongs to the improvement of cyclone duster structure, particularly improved cyclone dust collector.
Background technology
Cyclone dust collectors are to utilize the centrifugal inertial force that acts in the air-flow rotary course on the grit, the dust arrester that grit is separated from air-flow.Cyclone duster structure is simple, volume is little, use extensive use in the dust removal by ventilation engineering easy to maintenance.The operation principle of cyclone dust collectors is: the common cyclone dust collectors of the motion of air-flow and grit are made up of cylindrical shell, cone and discharge pipe three parts in the cyclone dust collectors, as figure.Dust-contained airflow prolongs outer wall and rotates from top to bottom after entering deduster by tangent line, and the air-flow that this strand is rotated down is outer eddy flow.After outward turning flows to and reaches cone base, then upwards, prolong the axle center and rotate up, after the discharge pipe discharge.The air-flow that this strand makes progress is called inside vortex.Downward outer vortex and the inside vortex that makes progress, both direction of rotation are identical.Grit wanted outside wall shift moving under the promotion of centrifugal inertial force when air-flow rotated.The grit that arrives outer wall under the acting in conjunction of air-flow and gravity, Yan Bi and fall into ash bucket.When air-flow rotated at a high speed downwards from dust remover roof, the pressure at top descended.Part air-flow can prolong outer wall and turns to tiny grit, reach the top after, along the rotation of discharge pipe outer wall downwards, discharge again from discharge pipe.This strand swirling eddy is called vortex.
The air-flow of actual cyclone dust collectors is then very complicated, except tangential and axial motion, also has motion radially, and the radial velocity of outer vortex is for entad, and the radial velocity of inside vortex is then outside.The tangential velocity of vortex is with the reducing and increase of radius, and the tangential velocity of inside vortex is that radial velocity is uneven along the distribution of height with the reducing and reduce of radius, and big bottom, top is little.The separation of entad moving to grit of outer eddy airstream is disadvantageous, and some tiny grit can enter inside vortex under the drive of air-flow entad, discharge from discharge pipe then.Grit in the outer vortex is at the air-flow of the power=centrifugal inertial force that the radially is subjected to+entad motion active force to grit.If centrifugal inertial force is greater than the active force of the air-flow that entad moves to grit, outwards wall shift is moving under the effect of centrifugal inertial force for grit; If to the active force of grit, grit enters inside vortex to centrifugal inertial force under the promotion of air-flow entad, discharge deduster at last less than the air-flow of entad motion.
The factor that influences the cyclone dust collectors performance is as follows: 1. inlet velocity; 2. cylindrical shell directly and the discharge pipe diameter; 3. the cylindrical shell of cyclone dust collectors and cone height; 4. the tightness of cyclone dust collectors bottom; 5. the centrifugal force of the flow pattern of air current composition and generation in the cylindrical shell; Exhaust duct stretches into the length of cylindrical shell.Because above-mentioned factor has determined the quality of the dust removing effects of deduster, and have deduster now when satisfying above-mentioned factor, its dust removing effects is still relatively low, the cost height, and energy consumption is big.
The utility model content
The purpose of this utility model is to provide a kind of improved cyclone dust collector, and it is rational in infrastructure, reduces the dust quantity that removes of subordinate's wet type and cloth bag, reduce blower fan power consumption, realize that easily cost is low, commercial Application is extensive, the society and the environmental benefit that produce are remarkable, and be energy-saving and cost-reducing.
The purpose of this utility model is achieved in that a kind of improved cyclone dust collector, comprise the dedusting cylindrical shell that constitutes by cylindrical barrel and the cone-shaped cylindrical shell that is positioned at its below, the upper end nozzle sealing of cylindrical barrel, cone-shaped cylindrical shell lower ending opening, the tangential blast pipe that is communicated with it is being set on the barrel of cylindrical barrel top, exhaust duct stretches in the cylindrical barrel from cylindrical barrel upper end with vertical state, is connecting the uniform cylindrical drum that is provided with through hole on the perisporium being positioned at the lower end of stretching into the cylindrical barrel exhaust duct.
Because the exhaust duct lower end in stretching into the utility model dedusting cylindrical shell has been connected with the cylindrical drum of water conservancy diversion dedusting effect, be evenly equipped with perforation on this cylindrical drum barrel, the length of cylindrical shell influences the efficient of deduster, the cylindrical shell axial length is lacked very much no flow pattern, oversizely then grit can be blown out the air channel from outlet, not have the effect of dedusting on the contrary.In order better to organize air to enter flow pattern in the deduster, guarantee higher centrifugal force, therefore adopt expanded metal lath in the exhaust duct lower end, form a cylinder trunnion that filtration is arranged, so both convenient construction and industry are made, and flow pattern and runner are preferably arranged again, and the mesh order number of cylindrical drum is definite according to dust size and the humidity situation back that experimentizes, the axial length of cylindrical drum will be as the criterion not stop air quantity simultaneously, can well improve the whole efficiency of cyclone dust collectors.The utility model is rational in infrastructure, reduces the dust quantity that removes of subordinate's wet type and cloth bag, reduces blower fan power consumption, realizes that easily cost is low, and commercial Application is extensive, and the society and the environmental benefit of generation are remarkable, and be energy-saving and cost-reducing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a sectional structure schematic diagram of the present utility model.
The specific embodiment
A kind of improved cyclone dust collector, as shown in Figure 1, comprise the dedusting cylindrical shell that constitutes by cylindrical barrel 2 and the cone-shaped cylindrical shell 5 that is positioned at its below, the upper end nozzle sealing of cylindrical barrel 2, cone-shaped cylindrical shell 5 lower ending openings, on cylindrical barrel 2 top barrels, the tangential blast pipe 1 that is communicated with it is being set, exhaust duct 3 stretches in the cylindrical barrel 2 from cylindrical barrel 2 upper ends with vertical state, is connecting the uniform cylindrical drum that is provided with through hole on the perisporium being positioned at the lower end of stretching into cylindrical barrel 2 exhaust ducts 3.
