Expose a series of problems:
1, by-product wood vinegar and wood tar do not find the approach of a large amount of business applications, and a fashion cannot be dissolved all, can send out
Raw " swell-warehouse " phenomenon.
Wood vinegar is dark brown liquid, and wherein organic acid content is up to 10%~15%, and toxic, acidity is very strong, there is corrosion
Property.Wood tar appearance is brownish black flowable liquids, and smell with irritating is made of a large amount of oxygenatedchemicals, which includes
Acetic acid, phenol, alcohol, ketone and carbohydrate and some acetal compounds, ingredient is sufficiently complex, so having thermal stability poor, easily old
Change, the disadvantages of viscosity is big and sour corrosion (pH value 2.5), is such as not seeking to dissolve all of which, serious two will be generated
Secondary pollution.
In fact, since this problem must not solve, tens of set commercial plants that trimerization company builds up and puts into operation at home
It is halted by local environmentally friendly authorities, not only company is made to get into a difficult position, more it is a concern that this result is there is a possibility that agriculture
The technology of crop material charing this Huimin that benefits the nation of returning to the field-soil improvement fails before being carrying out, troubling；
2, wet feed material enters furnace, and the moisture in stalk particle raw material is transferred completely into pyrolysis steam state product, increases the wooden vinegar
The yield of liquid, the concentration for reducing wood vinegar, the energy consumption for increasing retort, the energy consumption for increasing condensation cooling recovery system.
According to disclosed in trimerization biomass new material Science and Technology Ltd., when stalk particle raw aqueous 15wt%, wood vinegar yield
It is 26%.The moisture of 15wt% contained by raw material fully enters in this 26% wood vinegar, and the moisture that pyrolytic process generates only has
11% or so.
Although containing there are many compound for having application potential, application of the domestic and foreign scholars to them in wood vinegar and wood tar
Approach has carried out difficult exploration, it was found that a variety of application approaches in industry, traffic and agricultural.Although they are technically
Be it is feasible, it is only economically still unreasonable, therefore can not yet find stable market.It is expected that solving this situation, it will take time.
Summary of the invention:
In this context, it need to look for another way, strategic adjustment is carried out to straw carbonization process flow.For this purpose, this hair
Bright to provide a kind of rotary retort of the biomass for producing or not wood vinegar less, task is can be according to the market of wood vinegar
Supply and demand situation, the flexible yield for adjusting wood vinegar, produces or not wood vinegar, the technical measures taken are less: using drying
Stalk enters furnace, promotes its quality to reduce the yield of wood vinegar, increase its concentration；It adjusts pyrolysis gaseous products and sends to direct burning
With the ratio for being sent to condensate recovery system；
1. partial thermal decomposition gaseous products are sent to condensate recovery system, to obtain when wood vinegar still has certain market demand
Take the wood vinegar that can meet the market demand；
2. pyrolysis gaseous products are all cooled down by condensation, when wood vinegar is vigorous constantly without the market demand with cold combustion gas
As revolution retort heat source；
3., using pyrolysis gaseous products without cooling is condensed, all on the spot, just heat is fired when wood vinegar is without the market demand
It is burnt into high-temperature flue gas, as revolution retort heat source.
With reference to the accompanying drawing, the invention will be further described.
Detailed description of the invention:
Fig. 1 is the flow diagram for the commercial plant that trimerization company builds up and puts into operation at home.
Fig. 2 is the flow diagram that the present invention produces wood vinegar less.
Fig. 3 is the flow diagram that the present invention does not produce wood vinegar.
Produce the flow diagram of wood vinegar less referring to fig. 2.Straw particle is in waste heat drying oven, with revolution retort export
Flue gas it is dry after carbonized, benefit is:
1. siccative carbonizes, the moisture of 15-20% does not just enter retort in raw material, reduces the energy consumption of retort；
2. these moisture will not enter in pyrolysis steam state product, the energy consumption of condensation cooling system is reduced；
3. reducing the yield of wood vinegar, the concentration of wood vinegar is increased, improves the quality of wood vinegar, reduces the wooden vinegar
