Description
Technical field
The utility model relates to pipe technology field, is specifically related to a kind of composite material conduit for interchanger, more precisely relates to a kind of silumin composite material conduit be applied in heat exchanger of riser of coke oven.
Background technology
The high efficiente callback of the residual heat resources produced in coke making process flow process utilizes, and is to set up the energy-conservation Main way in resources conservation, eco-friendly green coke-oven plant, is also one of main path reducing coke oven energy consumption.How to find a kind of rational material to replace coke oven coke oven uprising tube, meet high temperature, wear-resisting, corrosion resistant requirement, be the key of better utilised waste heat simultaneously.
But, because existing general carbon steel piping is not able to take high temperature and its corrosive gases of coal oven dithio-gas, thus cause the upcast body of general material after use for some time, to occur corrosion-deformation, the phenomenon such as to penetrate, the long safe operation of coke oven cannot be competent at.
Now, have part to adopt senior alloy material tube to solve high temperature resistant, wear-resisting, corrosion resistant problem, through measuring and calculating, material cost is too high, and the return period for the recycling of residual heat resources lengthens relatively, and effect is had a greatly reduced quality.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of high temperature resistant, wear-resisting, corrosion resistant silumin composite material conduit, and it has long service life, and can meet short, the effective requirement of afterheat energy-saving resource recycling cycle.
The technical scheme realizing the utility model object is as follows:
Silumin composite material conduit, comprises the body with inwall, and the inwall of body is provided with abrasion-proof corrosion-proof high-temperature-resistant layer, and described abrasion-proof corrosion-proof high-temperature-resistant layer is made up of silumin wearing layer and nano anti-corrosive heat resistant and wear resistant layer; Described silumin wearing layer overlays on inboard wall of tube body and forms internal layer, and described nano anti-corrosive heat resistant and wear resistant layer overlays on the internal layer internal surface formation internal skin that silumin wearing layer is formed.
Further, in order to make silumin high-abrasive material and nano anti-corrosive heat resistant and wear resistant material better merge, ensure the intensity connected, described nano anti-corrosive heat resistant and wear resistant layer is by the internal surface of self-propagating high-temperature technology welding in silumin wear resistant inner layer.

Have employed technique scheme, arrange abrasion-proof corrosion-proof high-temperature-resistant layer at inboard wall of tube body, and abrasion-proof corrosion-proof high-temperature-resistant layer is made up of silumin wearing layer and nano anti-corrosive heat resistant and wear resistant layer, the pipeline of this spline structure can reach following technique effect:
(1) owing to being provided with abrasion-proof corrosion-proof high-temperature-resistant layer at inner-walls of duct, be assembled to after in heat exchanger of riser of coke oven like this, can ensure coke oven for a long time, continuous seepage safely and steadly, thus recycle the sensible heat of coke oven coke oven uprising tube raw gas continuously and stably;
(2) the abrasion-proof corrosion-proof high-temperature-resistant layer thickness be arranged in pipeline accounts for smaller, make use of the inner diameter volume of original pipeline so to greatest extent, do not change the circulation area of the raw gas of upcast, ensure when there is a large amount of raw gas, the smooth outflow of raw gas, the safety in production being conducive to upcast runs, and also ensure that can the output steam of continous-stable simultaneously;
(3) by the rational proportioning of thickness of silumin layer and nano anti-corrosive heat resistant and wear resistant layer, and by utilizing self-propagating combustion technique silumin high-abrasive material and nano anti-corrosive heat resistant and wear resistant material to be fired in metallic conduit to obtain, play Wear-resistant, high-temperature resistant and corrosion resistant effect, effect is better.
(4) the utility model silumin composite material conduit, the application of its nano anti-corrosive heat resistant and wear resistant layer, improves the heat conductivility of pipeline, is conducive to the heat trnasfer of interchanger.
