Abstract
The invention discloses a cyclone dust catcher with increased inner wall friction resistance. The cyclone dust catcher comprises a cylinder body, an exhaust pipe, an air inlet pipe, and a conical sedimentation cylinder of which the upper part is larger and the lower part is smaller, wherein the exhaust pipe is vertically arranged in the center of the cylinder body; a rotary flow channel descending spirally from outside to inside is formed between the exhaust pipe and the inner wall of the cylinder body; the air inlet pipe is arranged along the tangential direction of the outer wall of the upper end of the cylinder body, and is communicated with the rotary flow channel; the lower end of the cylinder body is provided with the sedimentation cylinder, and is communicated with the rotary flow channel; the lower end of the sedimentation cylinder is provided with an ash exhaust hole; and continuous spiral ribs are welded on the inner wall of the cylinder body. Due to the adoption of the way, the roughness and friction resistance of the inner wall of the dust catcher can be increased, the on-way energy loss effect is enhanced, the kinetic energy of air current and dust particles is consumed, dust particles in rapid air current play a role in directly resisting on the front face, air current and dust particles descend rapidly after being slowed down, the dust catching efficiency of equipment is increased, and a remarkable environmental protection benefit is achieved.
Description
Technical field
The present invention relates to the cyclone dust collectors field, particularly relate to the cyclone dust collectors that a kind of inwall frictional resistance increases.
Background technology
Cyclone dust collectors are devices that the centrifugal force that utilizes dust-contained airflow to rotate to produce separates grey grit and capture from gas; Compare with sack cleaner, electrostatic precipitator, desulfurizing dust-collector; Simple in structure with it, volume is little, manufacturing is easy to maintenance, advantage in the resistance or the like, becomes one of at present main cleaner.Be widely used in factory's kiln gas dedusting, boiler dust remover and factory's dust removal by ventilation etc.
Cyclone dust collectors when work, when dusty gas when air inlet gets in the spiral case with higher speed, air-flow will become circular motion by rectilinear motion, and upwards, flow downward.Stopped by top cover when the part in the swirling eddy rotates up and return, and the overwhelming majority is downward in the shape of a spiral along the shell inwall in the swirling eddy, flows towards cone, rotational gas flow in forming.Because the density of grit is bigger a lot of times than air, therefore the grit of rotation receives the effect of centrifugal acceleration doing in the circular motion with gas, will from air-flow, separate and get rid of to the spiral case inwall, drops in the cone cinder catcher and discharges through ash discharging hole.
All the time, how improving the cyclone dust collectors efficiency of dust collection is the problem that current dedusting industry need solve.Cyclone dust collectors generally are used to capture the above particle of particle diameter 5 μ m, when dust concentration greater than 50mg/m
3The time, efficiency of dust collection can reach more than 80%.But work as dust concentration less than 50mg/m
3The time, the capture particle diameter is not high less than the particulate efficient of 5 μ m.
Summary of the invention
The technical problem that the present invention mainly solves provides the cyclone dust collectors that a kind of inwall frictional resistance increases; Increase the roughness and the frictional resistance of deduster inwall; Simultaneously the dust granules in the quick air-flow is played the front and directly block effect; Simple in structure, be easy to realize, improved the efficiency of dust collection of equipment.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: the cyclone dust collectors that provide a kind of inwall frictional resistance to increase comprise: cylindrical shell, exhaust duct, blast pipe, up big and down small taper settlement barrel, and said cylindrical shell center uprightly is provided with exhaust duct; Form the eddy channel that descends in the shape of a spiral from outside to inside between said exhaust duct and the cylinder inboard wall; The tangential is provided with blast pipe on the outer wall of said cylindrical shell upper end, communicates with eddy channel, and said cylindrical shell lower end is provided with settlement barrel and communicates with eddy channel; Said settlement barrel lower end is provided with ash discharging hole, is welded with continuous helical shape rib on the said cylinder inboard wall.
In preferred embodiment of the present invention, the material of said rib adopts cast iron or pottery.
In preferred embodiment of the present invention, accompany the high temperature insulating layer of basalt fibre and ceramic composite in the middle of said cylinder body outer wall and the inwall.
In preferred embodiment of the present invention, on the said cylinder body outer wall vibrating motor is installed.
The invention has the beneficial effects as follows: the present invention is welded with continuous helical shape rib on cylinder inboard wall; Can increase the roughness and the frictional resistance of deduster inwall, strengthen, consume the kinetic energy of air-flow and dust granules along journey energy loss effect; Dust granules in the quick air-flow is played the front directly block effect; Thereby descend rapidly after air-flow and dust granules are slowed down, improve the efficiency of dust collection of equipment, environmental benefit is remarkable.
