Abstract
The utility model discloses a flue heat-preservation structure with reinforcing ribs, which includes a flue shell and a rock-wool panel coated with a wire netting; the rock-wool panel is fixed on the flue shell through a self-locking board; wherein, a transverse reinforcing rib is arranged on the flue shell; an external heat-preservation layer is arranged outside the transverse reinforcing rib; and a dope with a lower emissivity is coated on the external heat-preservation layer. Compared with the prior art, the transverse reinforcing rib is arranged on the flue shell and a layer of polyurethane is coated on the outermost protection layer, thereby achieving the goals of protecting the metal protection layer of the flue from being eroded by the outside environment and preventing the heat inside the flue from radiating to the outside.
Description
Technical field:
The utility model relates to a kind of flue insulation construction, is specially a kind of flue insulation construction with reinforcing rib.
Background technology:
At present adopt traditional heat preserving mode for the insulation of flue in the engineering, promptly at the outside of pipeline parcel one deck rock wool or mineral wool as heat-insulation layer, the shape that again aluminium skin or iron sheet is pressed into pipeline is wrapped in the outside of heat-insulation layer as protective layer.The construction of this technology is simple, use also very general, but heat insulation effect usually falls flat, the development trend that incompatibility is present.
This insulation construction also exists a big defective in addition; because the protective layer of its outside is a metal level; its thermal conductivity factor is big; rapid with the heat exchange in the environment, the environment that scatters and disappears soon for the heat of coming, form thermal balance with external environment from heat-insulation layer conduction; particularly higher for flue temperature; this heat conduction is inevitable, and at cold district, this situation is just more outstanding.Metallic insulation also is vulnerable to the acid rain, ultraviolet radiation in the environment etc. and destroys and produce corrosion, and the heat conduction and the etching problem that therefore solve external protection become particularly important.
Summary of the invention:
For heat conduction and the etching problem that solves owing to the flue external protection makes heat insulation effect not reach the problem of expection, the purpose of this utility model is to provide the insulation construction of flue in a kind of flue gas desulfurization technique.
For achieving the above object, the utility model adopts following technical scheme:
A kind of flue insulation construction with reinforcing rib, comprise flue housing and the rock cotton board that is enclosed with wire netting, described rock cotton board is fixed on the flue housing by the self-locking plate, wherein the flue housing is provided with horizontal reinforcement ribs, described horizontal reinforcement ribs is outside equipped with external thermal insulation, scribbles the coating of low-launch-rate on the described external thermal insulation.
Described coating is preferably polyurethane coating.
Described external thermal insulation is a metallic insulation.
The described external thermal insulation top water gradient of setting up defences.
The utility model is on the basis of existing insulation construction; be provided with horizontal reinforcement ribs on the flue housing and brushing one deck polyurethane on the outermost layer protective layer; thereby the coat of metal that reaches the protection flue is avoided the erosion of external environment, the purpose that the heat of prevention flue inside is outwards dispersed.
Description of drawings:
Fig. 1 is the generalized section of the utility model flue structure.
Identifier declaration among the figure: flue housing 1, wire netting 2, rock cotton board 3, bar for line 4, self-locking plate 5, horizontal reinforcement ribs 6, external thermal insulation 7, coating 8.
The specific embodiment:
Core concept of the present utility model is: lay rock cotton board on the flue housing, with wire netting rock cotton board is wrapped up then, and be fixed on the flue housing, as heat-insulation layer by self-locking plate and bar for line.And then outside heat-insulation layer, lay outside the metal and protect, and pass through the polyurethane coating of spraying or brushing low-launch-rate on outside metal, protecting, thus reach the erosion that the coat of metal of protecting flue is avoided external environment, the purpose that the heat of prevention flue inside is outwards dispersed.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1, the utility model is the insulation construction of flue in a kind of flue gas desulfurization technique, the rock cotton board 3 that it mainly comprises flue housing 1 and is enclosed with wire netting 2, described rock cotton board 3 is fixedly mounted on the flue housing 1 by self-locking plate 5 and bar for line 4, wherein flue housing 1 is provided with horizontal reinforcement ribs 6, described horizontal reinforcement ribs 6 is outside equipped with outer metallic insulation 7, scribbles the polyurethane coating 8 of low-launch-rate on the described outer metallic insulation.
In addition, in order to prevent to form ponding on the outer metallic insulation 7, the top of outside metal, the protecting water gradient of also setting up defences.
The utility model is that brushing one deck polyurethane on the outermost layer protective layer, this coating both can protect the coat of metal of flue to avoid the erosion of external environment on the basis of existing insulation construction, can stop inner heat outwards to be dispersed again.
More than a kind of flue insulation construction with reinforcing rib provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
