Abstract
The invention discloses a method for purifying biomass dry distillation gas, comprising the following steps: (1) introducing dry distillation gas generated in a pyrolysis carbonization stage of a biomass into a dust collector; (2) connecting an outlet of the dust collector in the step (1) to an air cooling device, introducing the dry distillation gas into the air cooling device, and collecting condensates at the same time; and (3) introducing the dry distillation gas after air cooling in the step (2) into an adsorption device. According to the method, a dry purification mode is adopted and carbonized particles and tar components can be removed from the dry distillation gas, and the dust collector adopts a moving bed of particles to reduce the blockage probability of the adsorption device.

Background technology
Biomass energy is exactly the form of energy that solar energy is stored in biomass in chemical energy form, i.e., with biomass to carry
The energy of body.It directly or indirectly from the photosynthesis of green plantss, can be converted into conventional solid-state, liquid and gaseous state
Fuel, it is inexhaustible, nexhaustible, it is a kind of regenerative resource, while being also a kind of unique reproducible carbon source.Biomass energy
Source technology is a kind of new energy technology with broad based growth future.
The content of the invention
It is an object of the invention to provide a kind of biomass carbonization gas purifying method.
The purpose of the present invention is by the following technical programs implementing：
A kind of biomass carbonization gas purifying method, comprises the steps：
（1）The carbonization gas that the biomass pyrolytic carbonization stage produces are entered into dust arrester；
（2）Step（1）The outlet of dust arrester is connected with air cooling device, and carbonization gas enter air cooling device, while collecting condensate；
（3）By step（2）Carbonization gas after air cooling enter adsorbent equipment.
Further, the step（1）Dust arrester be cyclone dust collector；
The step（3）Middle adsorbent equipment is moving granular bed, and filler is granular pattern semicoke.
The invention has the advantages that：
The biomass carbonization gas purifying method that the present invention is provided, using dry cleaning mode, can remove the carbonization in carbonization gas
Granule and tar ingredients, dust arrester adopts moving granular bed, and the blocking for reducing adsorbent equipment may.
