Smell carry special fragrance, reduce smog and choke nose, realize the environmental protection recycling of elm sawdust, and preparation method is simple,
It is easy to produce.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A kind of environmental protection recycling method of elm sawdust, specifically includes following steps：
(1) it is sieved after elm sawdust being crushed to 60-100 mesh, is then placed in Ball-stirring mill and is ground into together with ball-milling medium
Powder, it is spare；
(2) by the powder of step (1) and potassium chlorate, magnesium carbonate, barium naphthanate, non-ionic polyacrylamide, acetone and plant
Object powder mixes, and the mixture obtained after stirring evenly is spare；
Wherein, the plant powder is mainly made of peppermint, rue, tansy, datura, eupatorium ageratoides grass and bladderwort；
(3) it dissolves the chitosan in 65-75 DEG C of water and chitosan solution is made, it is spare；
(4) above-mentioned mixture is put into module and is squeezed into bulk, be placed in cooling in refrigerating chamber, while hot will immediately after taking-up
Above-mentioned chitosan solution is cast in module, after chitosan solution and mixture solidification, you can obtain chips fuel block, realize
The environmental protection recycling of elm sawdust.
Preferably, the temperature in step (1) in Ball-stirring mill is 50-70 DEG C.
Preferably, the parts by weight of each raw material of mixture described in step (2) are：50-60 parts of sawdust, potassium chlorate 20-30
Part, 15-20 parts of magnesium carbonate, 20-25 parts of barium naphthanate, 5-10 parts of non-ionic polyacrylamide, 8-10 parts of acetone and plant powder
10-15 parts.
Preferably, the plant powder is mainly made of following raw material：15-20 parts of peppermint, 10-15 parts of rue,
13-15 parts of 13-15 parts of tansy, 10-20 parts of datura, 10-15 parts of eupatorium ageratoides grass and bladderwort.
Preferably, the mass fraction of chitosan solution described in step (3) is 60-70%.
Preferably, the indoor temperature of refrigeration is 2-4 DEG C in step (4), cooling time 20-40min.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
It is 1, of the invention that using fuel slug made from sawdust to have that inflammable, burning time is long, burning is abundant, ash content is few etc. excellent
Point, and the smell that generates carries special fragrance when burning reduces smog and chokes nose, realizes the environmental protection recycling of elm sawdust, and
Preparation method is simple, easy to produce.
2, the magnesium carbonate added in the present invention effectively reduces ash content as ash modifier, and potassium chlorate and barium naphthanate rise
To combustion-supporting effect, and barium naphthanate can also prevent that a large amount of black smokes are discharged when burning, and non-ionic polyacrylamide can make fuel slug
Burning is more complete, and the residual ash after burning, which can recycle, makees potash fertilizer, realizes the Efficient Cycle of " discarded sawdust-fuel-fertilizer ",
Energy conservation and environmental protection realizes the environmental protection recycling of elm sawdust.
3, the plant powder added in the present invention is mainly by peppermint, rue, tansy, datura, eupatorium ageratoides grass and bladderwort system
At；Wherein, active ingredient contained in datura, eupatorium ageratoides grass and bladderwort has toxicity, has the effects that poisoning, antibacterial, has
Effect prevents microorganism, ant, cockroach etc. to the erosion of sawdust burning block, extends sawdust burning block service life；Peppermint, rue and
Tansy has special fragrance, while also having certain antibiotic and sterilizing effect, while extending sawdust burning block service life,
Combustion fumes are also effectively reduced to choke nose.
