The primary energy such as oil, natural gas.Although fossil energy has pushed social progress, non-renewable energy resources but increasingly disappearing
Consumption totally, while also will produce serious problem of environmental pollution, seriously threaten the survival and development of the mankind.Biomass energy is one
The regenerative resource that kind can store can realize the zero-emission of carbon dioxide by itself carbon cycle, be one during utilizing
Kind reproducible carbon source, and on the earth biomass rich reserves, the status occupied in energy consumption structure is increasingly heavier
It wants.By technological means such as physics, chemistry, biologies, biomass can be converted into biological-based chemicals, and biomass is through hydrothermal liquefaction
It is in recent years in the hot spot direction that scientific research field is studied to obtain solid product.
Hydro-thermal method refer to it is a kind of in the pressure vessel of sealing, using water as solvent, by powder body material substance carry out it is molten
The method of solution and recrystallization to prepare material.Compared with other powder preparing methods, powder made from hydro-thermal method is sent out with crystal grain
Educate that complete, granularity is small, be evenly distributed, particle agglomeration is relatively light, the advantages that biological raw material inexpensively can be used.Currently, hydro-thermal
It is especially very active in academic research field in terms of method has been widely used in material preparation and chemical reaction.In reality
It tests in room, the biomass predecessor of certain forms is usually placed in autoclave by researcher, and under high temperature, condition of high voltage
Hydro-thermal reaction is carried out, then hydrothermal product the post-processing steps such as detached to, washed and dried again to prepare powder body material.By
In hydro-thermal and solvent-thermal process chemistry in the extensive use in technologic material field, especially high temperature and pressure hydro-thermal and solvent-thermal process
The importance of chemistry, the research to this field is all increasingly paid attention in countries in the world.The biomass production that hydro-thermal reaction prepares
Object complicated component, containing a large amount of fatty acid, phenols, bark mutter class, light ethylhexanal, light benzylacetone and other a small amount of aldehyde,
The substances such as alcohol, ketone, the difficulty that solid product is directly isolated from solid-liquid suspension object is higher, thus generally use in the lab
The mode of suction filtration detaches solid-liquid suspension object, to the solid product needed for obtaining further studying.
Suction filtration is so that the penetration by liquid in solid-liquid suspension is filtered by motive force or under the action of other external force and be situated between
Matter, and a kind of solid-liquid separation method that solid particle and other materials are retained down by filter medium.It generally needs in the lab
To pass through multiple tracks cleaning solution and carry out filtering and washing, traditional Suction filtration device usually requires experimenter using beaker or other appearances
Device is contained to and fro takes and adds cleaning solution, complicated for operation.Meanwhile the filter outlet of traditional experiment room Suction filtration device sets for level
It sets, finds to be easier to draw liquid into rubber tube by practical suction filtration experiment, and then enter vacuum pump, to easily cause vacuum
Pump damage filters the various detrimental effects such as efficiency reduction.In addition, Suction filtration device common clamping mode in laboratory is to use one
A Simple clamp, although this mode simple possible, it is not tight close enough to be easy to cause sealing, to reduce suction filtration efficiency,
And because the speed filtered is inherently very slow, some suction filtration processes even need several days or more time, needed for suction filtration
Cleaning solution dosage it is very big, and common Buchner funnel capacity very little is filtered, if not paying attention to may result in Buchner funnel
Cleaning solution drained, and then cause filter paper rupture so that the solid product in Buchner funnel is fallen in filter flask, cause to filter
All that has been achieved is spoiled for journey.Correspondingly, there is develop a kind of higher suction filtration system and pumping for being suitable for being separated by solid-liquid separation of efficiency for this field
