The cyclone dust collector comprises an air inlet pipe, a cyclone, an air outlet pipe, a spiral stream guidance blade, a conical dust collector and a dust outlet, the air inlet pipe is arranged on one side of the cyclone, the spiral stream guidance blade is fixed on the air outlet pipe and extend into the cyclone, the conical dust collector is connected to the lower bottom of the cyclone and is communicated with the cyclone, the dust outlet is arranged at the lower end of the dust collector, the air inlet pipe is designed in a spiral pipeline structure, traditional straight blow type air inlet pipes are replaced, one end of the air inlet pipe is an air inlet, and the other end is fixed onto and communicated with the outer wall of the cyclone. According to the mode, the cyclone dust collector with the spiral air inlet pipe can change flow conditions of airflows inside the cyclone, possibilities of secondary dust raising and dust rising circulation phenomena of the conical portion are effectively reduced, centrifugal force of dust particles is increased because the rotation speed of airflows inside the dust collector is increased, fine particles which cannot be removed by traditional cyclone dust collectors can be removed, and the cyclone dust collector has high dust particle separation efficiency.
Description
Technical field
The present invention relates to the cyclone dust collectors field, particularly relate to a kind of cyclone dust collectors that have the spiral blast pipe.
Background technology
Cyclone separator is to utilize rotation centrifugal force that dusty gas produces, and the gas-solid separator of a kind of dry type with dust is separated from air-flow is widely used in industries such as chemical industry, oil, metallurgy, building materials, mining industry.Have remarkable advantages such as simple in structure, that production capacity is big, volume is little, reduced investment, simple and convenient operation and maintenance, during-operation service expense are low, especially effective for the dust that captures, separates more than the 5-10 μ m.
Use in the cyclone dust collectors maximum be the cyclone dust collectors of traditional tangential entry form; It mainly comprises air inlet pipe and spiral case, and the spiral case center uprightly is provided with exhaust duct, and exhaust duct is provided with guide vane; Form the interior eddy channel that descends in the shape of a spiral from inside to outside between exhaust duct and the spiral case inwall; The spiral case lower end is connected with the taper cinder catcher, and the inner chamber upper end of cinder catcher links to each other with interior eddy channel, and the lower end is provided with ash hole.During 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.
But; Air inlet pipe axis in the cyclone dust collectors of existing tangential entry form is vertical with spiral case inward turning air duct axis, because air-flow is rotated down after the top tangential direction gets into deduster, this must cause that the dust remover roof turned letter forms eddy airstream and produces top ash ring; The ash ring guide vane on blast pipe rotates when downward; Can mix at rotational gas flow on blast pipe porch and the " clean " exhaust gas, the formation secondary is raised the wind problem, influences the efficiency of dust collection of deduster; Secondly, the blast pipe of existing deduster is directly to blow into tube, and air-flow just is rotated after getting in the tube, and portion gas revolves motion on still can carrying out, and secondary dust phenomenon also can occur, makes the gas-solid separating property of deduster reduce.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of cyclone dust collectors that have the spiral blast pipe, can effectively reduce the secondary dust problem that conical section occurs in the existing cyclone dust collectors, has avoided the possibility that the upper dust-ring phenomenon takes place in the cyclone.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of cyclone dust collectors that have the spiral blast pipe are provided, comprise: blast pipe, cyclone, exhaust duct, spiral stream guidance blade, conical cinder catcher and ash discharging hole, said blast pipe are located at cyclone one side; Fixedly spiral stream guidance blade and lower end extend in the cyclone on the said exhaust duct; Said cyclone lower end is connected with conical cinder catcher and communicates with cyclone, and said cinder catcher lower end is provided with ash discharging hole, and said blast pipe is the helical pipe structure; One end is an air inlet, and the other end is fixed with the cyclone outer wall and communicated.
In preferred embodiment of the present invention, 5 ° ~ 10 ° of whole declivities of said blast pipe and cyclone are fixed.
In preferred embodiment of the present invention, said blast pipe helical pipe internal diameter is reduced to cyclone outer wall direction by air inlet gradually.
In preferred embodiment of the present invention, said cyclone and cinder catcher inwall are lined with basalt fibre and Ceramic Composite dope layer.
The invention has the beneficial effects as follows: the present invention is through improving its structure on traditional cyclone dust collectors basis; Not only make the flow regime of air-flow in the spiral case be able to change; The reentrainment of dust and the possibility of having avoided the upper dust-ring phenomenon to take place of conical section have been reduced effectively; And, can remove the inexpungible fine particle of traditional cyclone dust collectors owing to air-flow rotary speed in the deduster has increased the centrifugal force of grit, possess higher dust granules separative efficiency.
Description of drawings
Fig. 1 is the structural representation that the present invention has cyclone dust collectors one preferred embodiment of spiral blast pipe;
The mark of each parts is following in the accompanying drawing: 1, blast pipe, 11, air inlet, 12 helical pipes, 2, exhaust duct, 21, guide vane, 3, cyclone, 4, the taper cinder catcher, 5, ash discharging hole, 6, basalt and Ceramic Composite dope layer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises: blast pipe 1, cyclone 3, exhaust duct 2, spiral stream guidance blade 21, conical cinder catcher 4 and ash discharging hole 5, blast pipe 1 are located at cyclone 3 one sides; Fixedly spiral stream guidance blade 21 and lower end extend in the cyclone 3 on the exhaust duct 2; Cyclone 3 lower ends are connected with conical cinder catcher 4 and communicate with cyclone 3, and cinder catcher 4 lower ends are provided with ash discharging hole 5, and blast pipe 1 is helical pipe 12 structures; One end is an air inlet 11; The other end is fixed with cyclone 3 outer walls and is communicated, and adopts helical pipe to replace traditional type tube that directly blows, and makes dusty gas after the helical pipe high speed is rotated, enter into cyclone; Guaranteed to do " underspin " motion after air-flow gets into cyclone, improved the efficiency of dust collection of deduster.
Further; 5 ° ~ 10 ° of blast pipe 1 whole declivities are fixing with cyclone 3; Make air-flow in rotation, guarantee downward rotation, and this inclination angle also guaranteed grit when bounce-back absolute refraction down, reduced gas and got into the possibility that occurs upper dust-ring behind the cyclone.
