Abstract
The utility model discloses a sudden-expansion environment-friendly cyclone cylinder comprising an airflow inlet, an inner cylinder, a volute casing body, a main body, an upper vertebral body, a lower vertebral body and a blanking port. The sudden-expansion environment-friendly cyclone cylinder is characterized in that the volute casing body is a volute casing formed by three circles with different radiuses; the angle of the volute casing is 270 degrees; the inclination angle of the bottom surface of the airflow inlet is 45 degrees; and the upper ends of the upper vertebral body and the lower vertebral body are both provided with sudden-expansion bodies. By utilizing the sudden-expansion environment-friendly cyclone cylinder, the resistance is reduced, the separation efficiency and the dust collection efficiency are improved simultaneously as far as possible, the dust emission and the energy consumption are reduced, and the effects of well protecting the environment and improving the production efficiency are achieved.
Description
Technical field
The utility model belongs to novel concrete grog production equipment technical field, and the part of the precalcining system before the clinker burning rotary kiln is a kind of device that improves the cyclone cylinder separative efficiency.
Background technology
Cyclone preheater is one of capital equipment of System during New Style Dry-Process Production, generally is comprised of multistage cyclone cylinder and connecting pipe.Connecting pipe mainly plays heat exchange action, and cyclone cylinder mainly plays gas solid separation and solid phase collecting action.
Manufacture of cement is the process of a high energy consumption, high pollution, and the energy consumption of firing system accounts for the overwhelming majority, and the key that reduces the firing system energy consumption is to reduce the interior circulation of material and the material outside circulation of cement firing system, improves system's heat exchange efficiency.The separative efficiency of present cyclone cylinder is low causes firing system tail gas dustiness large, and the loss of dust heat content is large, and system's hear rate rises.Particularly obtain gradually people's attention at recent PM2.5, so it is imperative to reduce the dust granules discharging.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of cyclone cylinder of sudden expansion environmental protection; improve as much as possible cyclone cylinder separative efficiency and dust-collecting efficiency when making great efforts to reduce resistance; reduce dust emission and energy consumption, the effect that reaches better protection of the environment and enhance productivity.
The utility model adopts following technological means to realize goal of the invention:
A kind of cyclone cylinder of sudden expansion environmental protection, comprise air flow inlet, inner core, volute body, main body, upper centrum, hypocentrum and feed opening, it is characterized in that: described volute body is the spiral case that is made of three different circles of radius, the spiral case angle is 270 °, the angle of inclination of described air flow inlet bottom surface is 45 °, and the upper end of described upper centrum and hypocentrum all is provided with the sudden expansion body.
As the further restriction to the technical program, described inner core upper end is provided with the necking down structure.
As the further restriction to the technical program, described feed opening is the inclination tapered structure.
Compared with prior art, advantage of the present utility model and good effect are: volute body of the present utility model adopts 270 ° of large volute type structures of three-core, and the spiral case cornerite is large, reduces inner little into and out of interference in air flow, thereby reduce the possibility that forms eddy current, so reduced the drag losses of cyclone cylinder; The slope of designed air flow inlet is 45 °, makes to increase the charging aperture area when buildup not occuring satisfying, and can effectively control inlet air flow speed and air-flow in the rotary speed of inner core, improves separative efficiency and reduces drag losses; It is tapered that feed opening adopts, can cylinder in the gas local resistance loss of turning back and producing, become cyclone-type when material stream is flowed out, improve the heat exchange efficiency in the next stage cyclone cylinder; Two sudden expansion body structures that this cyclone cylinder adopts, namely be provided with the sudden expansion structure between cylinder and cone and between upper lower cone, when the gas material flows to when reaching cylinder and interpyramidal sudden expansion because ventilation-sectional area increases suddenly, the gas material runs off fast, powder sinks under Action of Gravity Field, thereby has improved separative efficiency, gas material stream in upper cone due to the interface become gradually under speed become gradually large, above-mentioned effect again occurs when arriving the interpyramidal sudden expansion in up and down, thereby effectively improve separative efficiency; Described inner core on top edge is provided with the necking down structure, both can adopt large inner core to reduce SR, also can play to stop that dust from the eliminating of cyclone cylinder inner core, improves dust-collecting efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is done further to describe in detail.
Referring to Fig. 1 and Fig. 2, the utility model comprises air flow inlet 1, inner core 2, volute body 3, cylinder 4, upper cone 5, lower cone 6, feed opening 7, sudden expansion body 8, necking down structure 9, described volute body 3 is the spiral cases that are made of three different circles of radius, the spiral case angle is 270 °, dust-contained airflow entrance 1 is the pentagon of 45 ° for the hypotenuse angle, and the upper end of described upper centrum 5 and hypocentrum 6 all is provided with sudden expansion body 8.
Described inner core 2 upper ends are provided with necking down structure 9.
Described feed opening 7 is the inclination tapered structure.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
