Further, the preceding pipeline elbow of the primary separator selects R >=2D elbows.
Further, the second-stage separator is efficient cyclone.
A kind of technique that rice husk matter charcoal is collected, including step is as follows：
Step one, biomass carbon carries out long-distance sand transport by Pneumatic conveying pipeline；
Step 2, sub-sieve is carried out by gravity sub-sieve device to biomass carbon, by the biomass carbon caking point in biomass carbon
Sift out system；
Step 3, the collection of biomass carbon is carried out by primary separator, second-stage separator, and the biomass carbon of collection is carried out
Packing；
Step 4, the gas after collection is purified by dust arrester, and tail gas is emptied by air-introduced machine.
Further, 300 DEG C of the temperature ＜ of the biomass carbon.
Further, hermetic bag vacuum or nitrogen-filled packaging are used after the biomass carbon is collected, such as：Tin film package bag, aluminium film
Packaging bag, packaged by plastic film etc..
Principle of the invention is：
Its density of biomass carbon is small, frangible, easily be bonded with tar in production process to form biomass carbon caking.It is simultaneously raw
Material charcoal forms the high temperature carbon block for being difficult cooling in charing, because the specific surface area of biomass carbon is big, the activity of biomass carbon
It is good, easily there is resume combustion after being combined with oxygen.The present invention is sent using wind and conveys biomass carbon and further cool down, defeated
Give, collect during reduce the impact of biomass carbon, the integrity degree of biomass carbon is kept, first with gravity sifter by biomass
Larger biomass carbon caking in charcoal is separated, then by separator collection biomass carbon.Second-stage separator is mainly to a fraction
The biomass carbon collected is difficult to from device such as：Powdery biomass carbon etc. is efficiently collected, it is to avoid biomass charcoal powder is in cleaning equipment
A large amount of aggregations, cause resume combustion, cause the damage of cleaning equipment.Cleaning equipment further collects little particle powdered rice hulls, control emptying
It is up to standard.
The invention has the advantages that：
1. the present invention is transmitted by wind pipe so that biomass carbon can carry out long-distance sand transport.
2. the present invention solves the cooling of biomass carbon by wind pipe transmission, it is to avoid resume combustion, it is to avoid to equipment
Damage.
