Description
Technical field
The invention belongs to coal pulverizer coal powder collection equipment technical field, be specifically related to coal pulverizer spiral rotary streaming coal powder collection device.
Background technology
Flyash receives to catch the thin ash got off from the flue gas after coal combustion, is the primary solids refuse that coal-burning power plant discharges; High-carbon cinder is the main coal pressure gasification technology because of in recent years rising then, and two classes all belong to the subparticle mixture divided containing certain carbon.Along with the development of power industry, the flyash discharge capacity of coal-burning power plant increases year by year, does not add process, will cause very large harm to environment, human body and biology.Current China is every year due to the cinder about about 400,000,000 tons that fire coal produces, and 12 last output will reach 5.7 hundred million tons, and stock's cinder that China does not utilize reaches more than 500,000,000 tons.The utilization rate that how so a large amount of cinders realizes recycling, improve cinder is become and has paid close attention to one of main points.
The grain graininess scope of flyash is 0.5 ~ 300 μm, and in ash content, the content of unburnt carbon is generally between 12% ~ 20%.The utilization rate of current ash content is about 67%, but thermal power plant mainly sells for building materials to the process of ash content, builds the road, backfill etc., the carbon of ash content is not reclaimed, be not only the waste to resource, and higher carbon content can have a negative impact for production of construction materials raw material to ash content.From ash content, reclaim carbon not only can make coal resources be fully used as electric power fire coal, and by carrying out point to hank one-level ash and two, three grades of ashes to ash content, can significantly improve the utilization rate of ash content, and also can improve with it is the performance of raw-material building materials.
A prerequisite of the various high added value purposes of development flyash is exactly reduce the carbon content in flyash, reduces loss on ignition, and this is the important foundation of comprehensive utilization flyash.But it is social economy's service that the prior art comprising above-mentioned patent also fails to fully utilize flyash fully, can not meet the situation that fly ash highly utilizes far away.
Therefore, low and the effective flyash of a kind of cost takes off slag classification and Floatation of Removal Carbon method and device, in order to realize the high efficiente callback of carbon dust in high-carbon fly ash and slag, can significantly improve its value, the comprehensive high-efficiency fully realizing industrial emissions utilizes simultaneously.
Summary of the invention
Object of the present invention is exactly to provide the low and effective flyash of a kind of cost to take off slag classification and Floatation of Removal Carbon method and device, in order to realize the high efficiente callback of carbon dust in high-carbon fly ash and slag, can significantly improve its value, the comprehensive high-efficiency fully realizing industrial emissions utilizes simultaneously.
The present invention is achieved through the following technical solutions:
Coal pulverizer spiral rotary streaming coal powder collection device, primarily of cone 1, is positioned at the escape pipe 2 of cone 1 upper end, is positioned at the feed pipe 3 of cone 1 side, is provided with backpitch passage 4 from top to down successively, along helical duct 5 and vortex tube 6 in described cone 1; Described backpitch passage 4 upper end is connected with gas outlet 2, and its lower end is connected with vortex tube 6; Described suitable helical duct 5 is connected with charging aperture 3; Spherical collecting chamber 7 is provided with in cone 1 lower end; Described spherical collecting chamber 7 is connected with feed pipe 3 by voltage-stabiliser tube 8, and described voltage-stabiliser tube 8 is provided with reverse flow check valve 9.
Described voltage-stabiliser tube 8 is in smoothing junction with feed pipe 3.
Described spherical collecting chamber 7 lower end is provided with the mouth 10 that gathers materials.
Compared with prior art, beneficial effect of the present invention is:
Cone 1 provided by the present invention, escape pipe 2, feed pipe 3, backpitch passage 4, along helical duct 5, vortex tube 6, spherical collecting chamber 7, voltage-stabiliser tube 8 and reverse flow check valve 9, coal dust is made to enter in cone 1 by feed pipe 3, and coal dust enters along suitable helical duct 5 when entering in cone 1, decrease resistance when coal dust enters, by centrifugal sedimentation effect, major part Pulverized Coal enters in spherical collection chamber 7 through cone 1 end, and most of fine grained and air are discharged along backpitch passage 4 by escape pipe 2, thus reach separation classification object, and due to the pressure in spherical collecting chamber 7 larger, rough coal powder is made to be easy to secondary back-mixing, and adopt the connection of the voltage-stabiliser tube 8 be connected with feed pipe 3, make spherical collecting chamber 7 identical with the pressure in feed pipe 3, and then suppress coal powder second back-mixing, and the employing of reverse flow check valve 9, the material that air can only be entered in feed pipe 3 in feed pipe 3 can not enter in spherical collecting chamber 7, decrease coal powder second back-mixing, great convenience is provided to user.
Beneficial effect of the present invention is: structure is simple, practical, can not only collect coal dust, and decrease coal powder second back-mixing, provide great convenience to user.
