It is not a kind of fixed bed reactors that can be improved biomass baking efficiency.
Background technique
The energy is the basis that modern society depends on for existence and development, although the development and utilization of fossil energy is conducive to economy
Development, but also increase greenhouse gases and the discharge of other pollutants, be unfavorable for the protection of natural environment and the health of the mankind
Level then develops production and cleans reproducible green energy resource and have become one of current most pressing project.China has every year
A large amount of draft, ligniform biomass source, but primordial matter that there are calorific values is low, density is low, degree of grinding is low, energy density is low,
The features such as efficiency of combustion is low, moisture content is high, volatile matter content is high, bulk volume is high, make biomass resource utilize on a large scale by
Certain limitation is arrived.In order to compete with fossil fuel energy carrier (such as coal, petroleum, natural gas etc.) or make jointly
With biomass need to being carried out series of preprocessing technique, such as baking, granulating, shaped brick etc. be close to improve its calorific value, energy
Degree, hydrophobicity etc..
Baking is the heat chemistry preconditioning technique that a kind of pair of biomass carries out, usually relatively at 200 °C to 300 °C
At a temperature of low, carried out under hypoxemia or inert atmosphere.Obtain that moisture content is low, energy density is high, Yi Fen after baking
The good solid product of broken, inflammable and hydrophobicity, this solid product, which is called, bakes biomass or biological coal, this baking
Biomass has the characteristics that similar low-order coal, can be used as high-grade fuel.
Currently, the device for being commercially used for biomass baking mainly includes drum reactor, screw reactor, fluidisation
Bed, compartment furnace, fixed bed, belt reactor etc., compared to other reactors, fixed bed reactors have element of installation it is simple,
The advantages that operation is easy.But the fixed bed reactors of biomass baking are currently used for there are low efficiency, product is cooling, collects process
The problems such as complicated, based on these there are the problem of, design the present apparatus, the above problem can be effectively improved.
Summary of the invention
The purpose of the present invention is to solve existing fixed bed biomass curing range baking efficiencies, and low, product is not easy to receive
The problem of collection, provides a kind of novel baking reactor, using magnet lantern ring sample introduction and sampling, so as to realize product in reality
Test the fixed bed reactors being quickly cooled down under atmosphere.The fixed bed reactors invented are easy to operate, product is easy to collect.
The present invention is achieved by the following technical scheme:
A kind of fixed bed reactors baked for biomass, including vertical furnace, the vertical furnace central part setting reaction
The temperature of device, the vertical furnace is controlled by temperature controller, and thermocouple is protruded into the reactor, and the thermocouple connects temperature control
Instrument；The reactor head connects sample feeding pipe by ground connector, sealing at the top of the sample feeding pipe, the sample feeding pipe it is a certain
Cross-section is provided with annular magnet and outer ring magnet simultaneously, and the annular magnet connects a pipeline, and the pipeline is stretched
Enter the interior simultaneously binder basket of reactor；The air inlet of the reactor and the air inlet of sample feeding pipe pass through pipeline and connect gas after connecing
Bottle, flow controller is installed at the cylinder outlet；The reactor bottom installs heating tape；The reactor underrun pipe
Filter is connected after the multiple condensers of road series connection, the filter outlet connects airbag.
Firstly, dried biomass is placed in material basket, it is uniformly mixed, is put into spare in drier.Then, furnace is opened
Temperature program is arranged in son, is passed through baking test gases used (hypoxemia or inert gas) guarantee after reaching experimental temperature
Air excludes clean.It opens ground connector and ready material basket is put into the crotch below pipeline, guarantee to expect in experimentation
Basket is firm.Ground connector is put into origin-location later, it is ensured that device good seal in experimentation.
At this point, material basket is located at the top position of reactor, guarantee biomass at this time without bake react under the premise of after
It is continuous to be passed through reaction gas for a period of time, when guaranteeing in reactor without air, pull down outer ring magnet, under magneticaction, inner ring
Shape magnet also moves downward, and will expect that basket is put into stove constant temperature zone position using magnet, starts to carry out baking reaction.
After reaction time set by reaching, magnet pull-up material basket is utilized again, makes to bake biomass in the case where testing atmosphere
Drop to room temperature.Since material basket is now in reactor top position, external temperature is room temperature, and rate of temperature fall can be improved in this way,
To also improve the baking efficiency of biomass.
Finally, taking out material basket, take out and bake biomass, weighs, it is spare to be put into sample sack.
The present invention has rational design, since biomass concentrates among material basket in the present apparatus, so biomass takes, puts material side
Just, loss reduces.
