Abstract
The invention belongs to the field of comprehensive utilization of biomass, in particular to a method for continuously discharging biomass charcoal in a plant-based fuel oil and fuel gas synthesis process, and provides a method for continuously discharging solid biomass charcoal generated in the plant-based fuel oil and fuel gas synthesis process. In a higher-pressure reaction environment, the method can mix water with the biomass charcoal to form serous fluid by controlling the proportion of the added water volume and the inner biomass charcoal, utilizes the pressure of a reaction system to continuously discharge the serous fluid, therefore continuously discharging the solid biomass charcoal under the condition that the pressure of a reactor is not influenced. The method effectively reduces abrasion to a valve, and the added water volume for regulating the serous fluid is 50-200 percent of the mass of biomass charcoal.
Description
Technical field
The invention belongs to technical field of biomass comprehensive utilization, a kind of continuous row's biomass charcoal method in plant base synthetic engine fuel and combustion gas technique particularly, thereby a kind of method that provides biomass charcoal generating in plant base synthetic engine fuel, combustion gas technique to discharge continuously.
Background technology
Biomass, as the reproducible clean energy of a kind of wide material sources, along with energy and environment problem increases the weight of day by day, are more and more subject to people's attention.Biomass directly and indirectly utilize form varied, wherein mainly contain the direct combustion power generation of biomass, gasifying biomass, biomass ferment producing methane, Progress in Production of Fuel-Ethanol.Plant base synthetic oil-air technology is a up-to-date high-tech content technology, this Technology origin is in physics and chemistry technical institute of the Chinese Academy of Sciences, obtained National 863, the support energetically of 973 projects, and in 2007, enter through engineering approaches amplification stage, relevant technical patent obtain the authorization (ZL200610011586.7).At present, this technology is being carried out ton industry amplification.Compare with technology such as gasifying biomass and biomass fast pyrogenations, this technology has realized biomass direct liquefaction and has changed into liquid fuel, can effectively improve the utilization ratio of biomass, the calorific value >=40MJ/kg of the fuel oil obtaining, H/C ratio is greater than 1.6, oxygen level <6%.Due to this reaction unit employing is that solid envelope is compressed into material, and reaction pressure is in 2Mpa left and right, the synthesis under normal pressure environment that is different from gasifying biomass and biomass fast pyrogenation technique, if adopt mechanical discharge to leak by build-up of pressure, and can be attended by emitting and hot loss of combustion gas, simultaneously very serious to the wearing and tearing meeting of valve, the work-ing life of greatly reducing valve.So need to explore a kind of reaction system pressure that do not affect, can not cause the continuous method of discharging of solid biomass charcoal of thermosteresis.
Summary of the invention
Object of the present invention is exactly in order not affect reaction system pressure, can not cause the continuous discharge that realizes solid biomass charcoal under the condition of thermosteresis in reactor, guarantees the steady continuous service of plant base synthetic oil-air technique.
Continuous row's biomass charcoal method in a kind of plant base synthetic oil-air technique of the present invention, that the biomass charcoal spiral producing in plant base synthetic oil-air technique is pushed to slurry mixing tank, then with tank in the water mix and blend that adds form slurries, the pressure of recycling reaction system itself, slurries are discharged by pipeline together, wearing and tearing to valve are little, thereby realized, arrange continuously biomass charcoal in the situation that not affecting reactor pressure.
The reaction pressure keeping in described plant base synthetic oil-air process reactor is 0.1-3Mpa.
Described biomass charcoal is remaining solid matter after plant base synthetic oil-air, and its main component is charcoal, calorific value > 16MJ/kg
Described plant base is herbaceous plant, xylophyta or their any mixture.
The mode that adds of described water is that high-pressure hydraulic pump quantitatively adds.
The described water yield that adds is the 50-200% of biomass carbonaceous amount.
Described herbaceous plant is selected from one or more the mixture in agricultural crop straw, reed, reed reed, Chinese silvergrass, bamboo, grass.
Described agricultural crop straw is selected from one or more the mixture in straw, wheat straw, maize straw, soybean stalk, cotton stalk, sweet potato vine.
Described xylophyta is selected from fallen leaves, bark, wood chip or their any mixture of trees.
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1. biomass charcoal is discharged process route chart continuously.
