Abstract
The utility model relates to an airflow type preprocessing device for drying and modifying biomass, which comprises a charging barrel, a speed regulation motor and a spiral feeding device. The charging barrel is arranged on a feeding port of the spiral feeding device, a discharge port of the spiral feeding device is communicated with one side of the lower portion of a vertical drying lifting cylinder, the bottom of the drying lifting cylinder is communicated with an air outlet of a draught fan, and the top of the drying lifting cylinder is communicated with an inlet of a cyclone separator. Raw materials of the biomass are dried and modified through usage of high temperature flue gas of a pyrolysis reactor heater, so that additional energy is not needed to be consumed for drying. Drying temperature and drying time of the biomass are adjusted through adjustment of flow and temperature of dry airflow, customized drying can be achieved according to characteristics of the raw materials and pyrolytic liquefaction of the biomass, a lignocellulose structure of the biomass achieves the preprocessing of modifying in a drying process, so that pyrolysis rate and volatile productivity are improved, and moisture in bio oil is reduced.
Description
Technical field
The utility model belongs to the drying and the modification technology field of biomass pyrolytic raw material, is specifically related to the drying and the modification pretreatment unit of biomass pyrolytic raw material.
Background technology
But living beings pyrolysis under secluding air or limited air fed condition obtains liquid, gas and three kinds of products of solid, and the productive rate of three kinds of products is relevant with the heating-up temperature and the rate of heat addition, it is bio oil that thermal decomposition product under middle temperature (450～550 ℃) and Fast Heating condition is mainly liquid, so pyrolytic process claims pyrolysis liquefaction again.
According to the raw material difference, the productive rate of biomass pyrolysis liquefaction primary product bio oil can reach 50～70%.Bio oil is the complex mixture that water and oxygen-containing organic compound are formed, and wherein moisture is up to 25～35%, and can not adopt conventional distil process or centrifugal method that these moisture are implemented to separate, and therefore had a strong impact on the quality and the use of bio oil.
Because the moisture overwhelming majority in the bio oil derives from biomass material, so before pyrolysis, biomass material is implemented the dry moisture that can effectively reduce in the bio oil.
The domestic and international biomass pyrolysis liquefaction technology of now having researched and developed out, or just raw material is carried out simple air-dry Exposure to Sunlight and handle, or adopt commercially available general baker that raw material is dried processing.Handle through simple air-dry Exposure to Sunlight, the moisture of biomass material generally still is more than 10%, and the moisture of the bio oil that pyrolysis obtains is usually all more than 25%; After adopting commercially available general baker to dry processing, though can reduce biomass material moisture and and then reduce the moisture of bio oil, also obviously have two big shortcomings: the one, consume the extra energy and be used to provide dry heat; The 2nd, drying process is not that special characteristics at living beings and pyrolysis liquefaction thereof design, thereby is difficult to obtain satisfied drying effect.
Summary of the invention
In order to reduce the moisture of biomass material, at the characteristics of living beings and pyrolysis liquefaction thereof, the purpose of this utility model is to provide a kind of and the dry and modification pretreatment unit of the matching used air-flowing type living beings of biomass pyrolysis liquefaction device.
The air-flowing type living beings are dry to comprise barrel, buncher and feeding screw with the modification pretreatment unit, and described barrel is positioned at the charging aperture place of feeding screw; The discharging opening of described feeding screw is being communicated with upright oven dry enhancing tube bottom one side; The bottom of oven dry enhancing tube is being communicated with the air outlet of air-introduced machine, and the top of oven dry enhancing tube is being communicated with the import of cyclone separator.
The diameter of described oven dry enhancing tube is the 60-200 millimeter, highly is the 1000-30000 millimeter.
The supporting use of the utility model and pyrolysis liquefaction device so can utilize the high-temperature flue gas of pyrolysis reactor heater that biomass material is carried out drying and modification preliminary treatment, does not need to consume the extra energy and is used for drying; And can regulate baking temperature and drying time by the flow and the temperature of regulating dry gas stream, can realize dry targetedly according to the characteristics of biomass material and biomass pyrolysis liquefaction, and in dry run, make the lignocellulosic structure of living beings obtain the modification preliminary treatment, make it to help separating out of pyrolysis devolatilization part, thereby improve pyrolysis rate and volatile producibility, and reduce the moisture in the bio oil.
Good effect of the present utility model is: utilize the high-temperature flue gas of pyrolysis reactor heater that biomass material is carried out drying and modification preliminary treatment, be not used for drying so do not need to consume the extra energy; By the flow of regulating dry gas stream and baking temperature and the drying time that temperature is regulated living beings, can realize dry targetedly according to the characteristics of biomass material and biomass pyrolysis liquefaction, and in dry run, make the lignocellulosic structure of living beings obtain the modification preliminary treatment, make it to help separating out of pyrolysis devolatilization part, thereby improve pyrolysis rate and volatile producibility, and reduce the moisture in the bio oil.Therefore, this living beings are dry has characteristics such as simple in structure, easy to operate, diverse in function and energy savings with the modification pretreatment unit.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, the air-flowing type living beings are dry to comprise barrel 1, buncher 2 and feeding screw 3 with the modification pretreatment unit, and the big footpath of the screw rod in the feeding screw 3 is that 60mm, path are that 40mm, pitch are 40mm.Barrel 1 is positioned at the charging aperture place of feeding screw 3, and the discharging opening of feeding screw 3 is being communicated with bottom one side of upright oven dry enhancing tube 4, and the diameter of oven dry enhancing tube 4 is 100 millimeters, highly is 2.5 meters.The bottom of oven dry enhancing tube 4 is being communicated with the air outlet of air-introduced machine 5, and the top of oven dry enhancing tube 4 is being communicated with the charging aperture of cyclone separator 6.
During use, the discharging opening of cyclone separator 6 is being communicated with the charging aperture of pyrolysis liquefaction device, and the air inlet of air-introduced machine 5 is being communicated with the exhanst gas outlet of pyrolysis liquefaction device.
