Abstract
A cyclone separator for titanium dioxide production comprises a barrel, a cone, an exhaust pipe and an outer sleeve, wherein the barrel is provided with an air inlet and an air outlet, the cone is connected with the lower end of the barrel, and the exhaust pipe and the outer sleeve are arranged inside the barrel. The cyclone separator for titanium dioxide production is characterized in that a spiral fin is arranged on the outer side of the exhaust pipe. Theoretically, according to the cyclone type separating theory and a structure of an axial type cyclone separation pipe, the spiral fin is added on the outer wall of an inner pipe of the cyclone separator, so that the number of rotating turns of air containing solid particles can be guaranteed, separation efficiency can be improved, equipment complexity for serially mounting a plurality of cyclone separators can be avoided, and troubles in connecting and mounting and high pressure drop during operation can be avoided as well. By adding a stop plate in the middle between the lower end of an exhaust pipe opening and the connection position of the cone and the barrel, an ash hopper on the lower portion of the cone is omitted, and particles can be effectively prevented from rising and back mixing. The cyclone separator for titanium dioxide production is simple in structure.
Description
Technical field
The utility model belongs to the plant equipment field, relates to the cyclone separator that titanium white production is used, and particularly can improve separative efficiency, improved cyclone separator.
Background technology
In the production of titanium white powder, the cyclone separator structure kind is very many, but all is the centrifugal force that utilizes the gas rotation contain solid particle to be produced, a kind of dry type gas-solid separating device that particle is separated from air-flow.Cyclone separator structure is simple, makes, installs reduced investment; Belong to static equipment, Operation and Maintenance is easy; Stable performance, operating flexibility is big; Do not receive the restriction of concentration of solid particles in gaseous species, the gas and temperature, pressure, range of application is very extensive.But still have deficiency, mainly be not high to the medium separative efficiency of fine particle (particle diameter≤5 μ m).The reason of this respect is that particle that the not enough and interior rotating vortex of gas rotation is prone to have separated is kicked up and carried secretly away.
General cyclone separator all is that the particle that relies on descending air-flow will concentrate at the wall place inserts ash bucket.Therefore can get into ash bucket by some gas inevitably, this part gas is always carried the parts of fine particle secretly, and to return cyclone separator simplified, gets into blast pipe, thereby influence separative efficiency.
Summary of the invention
The purpose of the utility model is to improve the separative efficiency of fine particle and gas, and cyclone separator of the prior art is improved, and through improving, compared with prior art separative efficiency improves greatly.
The utility model for realizing the technical scheme that goal of the invention adopts is; The cyclone separator that a kind of titanium white production is used; Comprise the cylindrical shell with air inlet and air outlet, the cone that is connected with the cylindrical shell lower end, at exhaust duct and outer sleeve that barrel is provided with, key is: the outer wall of described exhaust duct is provided with helical.
The principle of the utility model is, according to the structure of spiral-flow type separation principle and axialmode cyclone tube, the outer wall of inner tube of cyclone separator set up helical, both can guarantee to contain the rotating cycle of solid particle gas, improves separative efficiency; Many the cyclone separators of can avoiding again being installed in series cause equipment numerous and jumbled, and problem bigger than normal falls in pressure when being connected and installed trouble and operation.A baffle plate is set up at middle part between cone-cylindrical shell junction and exhaust pipe mouth lower end, cone bottom cancellation ash bucket.So also can prevent the particle back-mixing of kicking up effectively, structure is then simple relatively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 represents housing, and 1-1 represents air inlet, and 1-2 represents air outlet, and 2 represent outer sleeve, and 3 represent exhaust duct, and 4 represent cone, and 5 represent helical, and 6 represent anti-swirl baffle.
The specific embodiment
The cyclone separator that a kind of titanium white production is used; Comprise the cylindrical shell 1 with air inlet 1-1 and air outlet 1-2, the cone 4 that is connected with cylindrical shell 1 lower end, at the exhaust duct 3 and the outer sleeve 2 of cylindrical shell 1 set inside, key is: the outer wall of described exhaust duct 3 is provided with helical 4.
The bottom of sleeve 2 is equipped with anti-swirl baffle 6 outside.
Be provided with lid at air inlet 1-1 place, exhaust duct 3 is threaded with lid.The insertion depth of pipe is to regulate through the screw thread of cyclone separator top horizontal cover in the laboratory, and interior pipe and urceolus all use transparent lucite to make, and at the every vertically ring-type butter striped of coating wide lcm at a distance from l cm of outer wall of inner tube, outer tube inner wall.After repeatedly groping, reaching a conclusion, the pipe insertion depth can obtain higher efficient in suitably increasing, and promptly obtains bigger gas rotating cycle value.
During the utility model practical implementation; Through our many groups of tests, at the cyclone separator of only establishing 6 circle helical eddy current baffle plate in the air, separative efficiency reaches 89.1%; And establish the cyclone separator of 6 circle helical and the eddy current baffle plates of setting up defences simultaneously; Separative efficiency has reached 90.6%, compare with 78.4% of prior art improved many, the effect highly significant.
