Technical field

The present invention is a kind of timber dewatering, drying and carbonization integrated equipment for wastewater treatment and its processing method, and it is dry to belong to timber Dry and Wood carbonization processing technique field.

Background technique

Timber is four universally acknowledged big construction materials, and is a kind of reproducible green material, in state's people's livelihood It produces and is widely used in living.The timber ratio of strength to weight is big, is easily worked, and has beautiful decorative pattern and color, can conditioning, Has good environmentology feature.Therefore, timber is widely used always Wood construction and its product, indoor family from ancient times to the present Product is fitted up on tool, floor etc..Timber is as natural biomaterial, and other than having above-mentioned advantage, there is also some defects.Hold It is easily damaged by insects, mildew and rotten, phenomena such as in addition timber easily causes deformation, cracking and off-seam due to the variation of moisture occurs. These problems will lead to some quality and safety problem if there is on the Wood construction or woodwork manufactured, and life is caused to be endangered Danger and Business Economic Benefit are impaired.The above problem of timber mainly due to caused by the moisture of wood internal, timber only Have by reasonably drying, the above problem can be just alleviated or avoided by controlling moisture content.But certain special use conditions or Use environment require timber to carry out special processing could improve its dimensional stability, rotproofness, it is resistance to damage by worms and it is resistance to mildew etc. Performance.Wood carbonization can effectively solve above-mentioned problem, and Wood carbonization is physical treatment, does not use chemical agent, avoids To environment and using the pollution of crowd, it is widely recognized as in recent years by scholar and consumer.Timber after carbonization treatment, anti-corrosion are prevented Worm, timber size be stable, it is indeformable, do not crack, thorough degreasing, thermal insulation it is good, not hygroscopic.Wood color after carbonization is equal It is even, without color difference, improve the class of timber.Therefore it can be effectively improved the various aspects of performance of timber by carbonization, widen it Use scope improves the added value of timber-work.

It needs to control lower moisture content before Wood carbonization, otherwise carbonization will lead to the deformation of high-moisture percentage timber, implosion, stick up Song, or even scrap timber.Current carbonizing apparatus has a single function, and can only be carbonized to timber, cannot be by dry and carbonization Effective integration.The main reason is that timber drying time early period is too long, the effective time of carbonizing apparatus is occupied.Therefore, It needs to carry out depth drying in other drying equipments before Wood carbonization, the moisture content of timber is reduced to 4-6%, is then put again The kiln that enters to be carbonized is interior to carry out carbonization treatment.This process is complicated for operation, needs multiple loading, unloading, wastes time and labour Power, inefficiency, equipment occupy more.
