Description
Technical field
The utility model relates to a kind of bamboo and is wound around composite chimney.
Background technology
Chimney is one of the most ancient, most important environmental control system, and main effect is smoke evacuation, waste air, is widely used in industrial production.What generally adopt in the market is brick chimney, reinforced concrete chimney and steel stack three major types.These conventional chimneys exist to produce installs the shortcomings such as energy consumption is high, resource is not recycling, inwall is rough, long construction period, poor thermal insulation property, cost and maintenance cost are higher.
The patent No. is: 88208210.8, a kind of structure is mentioned: adopting blue bamboo through being processed into, getting through the inner septum in thick bamboo tube, heavy caliber is connected with chimney in the Chinese patent that patent name is " Bamboo chimney shaft ", and retain last barrier film of small-caliber end, be with holes around it.Its size of chimney made by technique scheme is limited, is generally that family uses, is not suitable for industrial application.
The patent No. is 201110035166.3, a kind of preparation method is disclosed: first Wet Winding Process one deck composite hoop layer on mould in the Chinese patent of patent name for " a kind of method using prefabricated component to manufacture large-scale composite material tubular body ", then above prefabricated composite material prefabricated component being wound on, again at wound thereon one deck composite hoop layer, the prefabricated component be wound between two-layer hoop layer is bound by the fiber of outer hoop layer, the resin-dipping of simultaneously being had more than needed by hoop layer, bonding, form axial layer, and hoop layer and axial layer, an entirety is become again by resin bonding, so move in circles, until designing requirement, form the composite product of hoop layer and axial layer alternately stacked 3 layers or sandwich construction.Described prefabricated component is the bamboo curtain splint shape component of main body and connecting line composition, and its main body is the strip material that polymer matrix composites employing pultrusion molding process is made.Defect and the deficiency of technique scheme are: these technical scheme raw material adopt polymer matrix composites, comprise the high energy consumption such as glass fibre, superhigh molecular weight polyethylene fibers, production process not environmentally, material that cost is high.And its structure and the application also have many different, do not have inner liner, and the bamboo curtain splint shape prefabricated component of resin-based main body and connecting line composition its be single direction, structural strength is not high enough.
Utility model content
Technical problem to be solved in the utility model overcomes deficiency of the prior art and provides a kind of inner wall smooth, high insulating effect, without the need to increasing thermal insulation layer, decrease dangerous vapors to corrode in the condensation of inwall in uphill process, cost is low, easy for installation simultaneously, and environmental protection, the reproducible bamboo of resource are wound around composite chimney.
The technical scheme in the invention for solving the above technical problem is: a kind of bamboo is wound around composite chimney, main body is cylindric, it is characterized in that: main body radial section comprises inner liner from the inside to the outside, structure sheaf and external protection coating, inner liner comprises the first inner liner and the second inner liner from the inside to the outside, the first described inner liner and the second inner liner are made by the fibrofelt or non-woven fabrics being stained with fire resistant resin, the fibrofelt of the first inner liner or its thickness of non-woven fabrics are less than the second inner liner, its resin adheres amount is greater than the second inner liner, it is outer and formed by resin-bonded solidification at inner liner that structure sheaf is thin bamboo strips used for weaving band multi-lay winding, structure sheaf outer surface has external protection coating.First inner liner adheres to more fire resistant resin, namely after solidification, the first inner liner resin layer thickness is greater than the second inner liner resin layer thickness, the inner liner made like this can meet high temperature resistant, the corrosion resistant requirement in chimney inside, and after solidification, inner surface is smooth, and steam can not be allowed at internal condensate.The structure sheaf made effective weight reduction while the mechanical strength ensureing chimney, convenient transport, and raw material good heat insulating, environmental protection, wide material sources, with low cost, produce, installation process is pollution-free.External protection coating generally should have radiation proof, the characteristic such as corrosion-resistant, anti-oxidant, in order to protect chimney internal structure, effectively extends the service life of chimney.
