Description
Technical field
The invention belongs to the piece-rate system technology of gas-solid, particularly a kind of gas solid separation technology that realizes through efficient backflow cyclone system.
Background technology
Along with the pay attention to day by day of the domestic environmental pollution that the PM2.5 fine particle is caused, it will be severeer that the Separation and Recovery of industrial dust≤2.5 μ m is required, thereby will consider to adopt various dedusting recovering meanses.Most convenient, the most succinct way are to adopt cyclone dust collectors; Yet general cyclone dust collectors are owing to self Secondary Flow and eddy current such as carry secretly at reason, for below the 10 μ m in addition the fine particle organic efficiency below the 5 μ m extremely low, even less than 5%; And bag-type dust, electrostatic precipitation or other wet method dedusting systems on the fund that has high input; Exist system complex, energy consumption big, the trouble of bringing successor operation to safeguard again, even cause secondary pollution.Then need a kind of dust pelletizing system ability and the general the same convenient operating maintenance of cyclone dust collectors, less energy consumption, have similar other dust pelletizing systems advantage efficiently again.
Summary of the invention
The objective of the invention is to the existing technical problem of above-mentioned existing dust arrester, provide a kind of simple in structure, energy-conserving and environment-protective to be easy to the efficient backflow cyclone system of safeguarding again.
In order to reach this target; The present invention adopts following technical scheme to be able to solve: the dust pelletizing system that efficiently refluxes comprises: former air-flow input pipe, blower fan, dust-contained airflow blast pipe, core formula separation assembly, core formula separation bubble blast pipe, cyclone separator, cyclonic air flow blast pipe and dust collection.Former air-flow blast pipe is connected with blower fan, is used for former air-flow input blower fan.Dust-contained airflow blast pipe one end is connected with blower fan, and the other end links to each other with the flat inlet of core formula separation assembly, is used for the air-flow input core formula separation assembly that blower fan is discharged.The flat outlet of core formula separation bubble blast pipe one end connection-core formula separation assembly, the other end connects the air inlet of cyclone separator, is used for the air-flow input cyclone separator that core formula separation assembly is discharged.Cyclonic air flow blast pipe one end is connected on the gas outlet of cyclone separator, and the other end is connected with former air-flow input pipe, is used for the air communication that cyclone separator is discharged is crossed former air-flow input pipe input blower fan to reach the purpose of circulating reflux dedusting.Powder outlet bottom at cyclone separator is provided with a dust collection, is used to collect the dust of separating.Core formula separation assembly comprises cylindrical shell, and cylindrical shell is provided with flat inlet, flat outlet and pure qi (oxygen) mouth outward, and flat discharge area is less than flat inlet, and flat inlet and the equal arranged tangential of flat outlet are at cylinder body outer wall; Said pure qi (oxygen) mouth has two, and the sectional area of pure qi (oxygen) mouth is arranged at the two ends up and down of cylindrical shell respectively less than cylindrical shell.Be provided with the core bucket in the said cylindrical shell and two core buckets are connected with described pure qi (oxygen) mouth respectively, be provided with cover plate in the junction of core bucket and pure qi (oxygen) mouth.
It is mobile to circle round in core bucket high speed after the dust-contained airflow entering core formula separator, form center high speed cleaning gas tream post, and the cleaning gas tream at center begins to discharge on a small quantity through the pure qi (oxygen) mouth after the several times circulation, until system balancing.Make that like this core formula separative element avoids Secondary Flow occurring and eddy current is carried secretly, guaranteed the high efficiency separation.
Make the air-flow that need separate in this system constantly circulate as the circularly-supercharged device in the native system to guarantee circulation power with blower fan; This circulation is with the separation of air-flow through abundant number of times; The possibility that makes dust be collected to get off has improved greatly, thereby has improved the separative efficiency of system to air-flow.
The gas solid separation efficient that helps to improve return-flow system is used in a plurality of core formula separation assembly combinations.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment system of the present invention is described in further detail:
Embodiment
As shown in Figure 1; The former air communication that needs separate is crossed in the former air-flow input pipe 41 input blower fans 1; Wherein former throughput is less than the circulating air flow in the blower fan 1; Former air-flow and circulating current are through getting into after blower fan 1 supercharging in the core formula separation assembly 2, and air-flow circles round mobile in core bucket 21 high speeds, form center high speed cleaning gas tream post; Wherein meeting the requirements of cleaning gas tream is discharged until system balancing by each pure qi (oxygen) mouth 23 of core formula separation assembly 2; Remaining dust-contained airflow enters in the cyclone separator 3 through core formula separation bubble blast pipe 44, and air-flow separates a part of dust granules in back through cyclone separator 3 to be collected in the dust collection 5, thereby remaining dust-contained airflow enters to get in the blower fan 1 in the former air-flow input pipe 41 through cyclonic air flow blast pipe 43 and carries out next round circulation gas solid separation.Suppose that a certain grade particle of former air-flow total amount is 1; Core formula separation assembly 2 grade efficient
; Cyclone separator 3 grade efficient
; Backflow dust pelletizing system grade efficient is
, and then the effectiveness formula of expression system service behaviour is:
if
;
; Then
this shows that this system's separative efficiency has obviously improved.
As preferably, can a plurality of core formula separation assembly 2 combinations be used to improve the gas solid separation efficient of return-flow system.
