Detailed description of the invention
Illustrating embodiments of the invention below in conjunction with the accompanying drawings, embodiment is not construed as limiting the invention:
Dust removal of calcium carbide furnace tar recovery system, it is characterised in that the discharge duct of furnace of calcium carbide is connected to cooler, cooler
Being connected to sack cleaner, sack cleaner is connected to can be by dust and the separate device of volatile tar.
Can be following any one scheme by dust and the separate device of volatile tar:
The most described can be the radiation airtight drum-type dry distilling kiln of heating, radiation heating by dust and the separate device of volatile tar
The gas outlet of airtight drum-type dry distilling kiln is connected to tar storage tank, and radiation is heated airtight drum-type dry distilling kiln and is also connected with dedusting
Ash silo.
In conjunction with Fig. 3, use this kind of structure dust and tar to be separated rapidly, but although this kind of structure relative to
Technique described in Fig. 1 can absorb tar, but airtight drum-type dry distilling kiln structure complexity is heated in radiation, and the heat of needs is many,
Safeguard complexity, it is difficult to cleaning.Cleaning speed is fast, convenient.And can clear up together by putty oil.
B. Fig. 4 is combined；Described dust and the separate device of volatile tar can be comprised housing, below housing, comprise ash
Bucket and the multistorey strainer mesh being in tilted layout；Also comprise absorption mouth above multistorey strainer mesh, absorb mouth and be connected to tar storage by pipeline
Tank.Described multistorey strainer mesh is metal structure, and metal structure is prepared for heating metal, which is connected conductor wire.Described metal structure
For electrical heating net.
The filter screen tilted, on the direction of air inlet, comprises the gas of volatility tar and the mixture of dust, dust meeting
Being blocked on filter screen, owing to electrical heating net itself can generate heat, tar can not depend on thereon, can only pass through subsequently through filter screen
Absorb mouth entrance tar storage tank to be recovered.
Using option b, its construction cost is 1/3rd of original technology, and it clears up convenient, and disposal costs are original
1/5th；It is difficult to block, does not haves the situation of sticky paste, separate thoroughly；Environment protecting is good, and tar and dust separation are thorough
The end.
In conjunction with Fig. 3, using this kind of structure, simple in construction, heated by filter screen, initiative filter screen can be heated and avoids tar
Adhere to, again can Chalk-dust filtering.
The further technical scheme of the present invention is, described in the multistorey strainer mesh aperture from the bottom up that is in tilted layout be gradually reduced；
Therefore can realize filtering layer by layer；Vertical passage is comprised on the right side of the described multistorey strainer mesh being in tilted layout；Shake is comprised on described housing
Dynamic structure；For the dust being accumulated on net, by shaking structure, can be fallen down by vertical passage.
The further technical scheme of the present invention is, described multistorey strainer mesh is metal structure, and metal structure is also connected with high pressure
Electricity, is lower electrode plate below housing, forms voltage difference, dust can be made charged between metal structure and the lower electrode plate of high-tension electricity
And then it is driven to lower section；Described lower electrode plate is network structure；Drive except gravitational settling, metal structure and lower electrode plate are formed
Electromotive field, is settled by driving after making dust charged, forms gravitational dust collection, electric precipitation and intensification and removes the resultant effect of tar removing.
As the most preferably, this patent can conveniently be carried out, and the mode of cleaning is by shaking structure to it
Carry out vibrations cleaning；As further preferred, can directly wash by water from top and be carried out.And relative to scheme, it is not
Can wash by water, because it keeps flat, and internal structure is complicated, it is difficult to realizes simplified cleaning, does not more use electrically heated isolation technics.
In a creative way, each effect above is individually present, moreover it is possible to complete the combination of the above results with a nested structure.
The technique effect that above structure realizes realizes clear.Part details not shown in figure.
It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, the most mutually
Restriction, but it can also be mutually combined in the case of not conflicting, and reaches multiple effect and jointly realizes.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of this area
Personnel, it should be recognized that the present invention is not restricted to the described embodiments, simply illustrate this described in above-described embodiment and description
Bright principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Both fall within claimed scope with improving.
