Abstract
The invention relates a tube used for dimethyl ether in the fields of the production of the chemical engineering and the application of new energy sources; the tube has three-layer or multilayer composite structures which are adhered mutually together. An inner layer 1 is made from organic material which is resistant to the corrosion of dimethyl ether and can be resistant to the corrosion and swelling of dimethyl ether and fluid medium with dimethyl ether; a middle layer 2 is a reinforcing layer prepared by weaving high strength organic material fiber or metal wire and can increase the intensity of the inner tube; an outer layer 3 is made from anti-aging rubber or plastic with protection function and can prevent the mechanical damage and the corrosion by external environment. The whole ofthe invention has light weight, good flexibility, less transportation resistance and excellent corrosion resistance to dimethyl ether. The invention can be used in various fields of the production andapplication of dimethyl ether such as loader tubes, industrial welding and cutting tubes, cylinders-filling tubes, connection tubes of gas appliance, civil gas transmission pipelines and the like; the invention can solve the technical problem of tubes used for the transmission of dimethyl ether and fluid medium with dimethyl ether and create conditions for the production and application of new energy sources.
Description
Technical field
The present invention relates to a kind of flexible pipe that is used for Chemical Manufacture and novel energy application, this flexible pipe is mainly used in the flowing medium of carrying dimethyl ether and containing dimethyl ether.
Background technique
Energy shortage in recent years and environmental protection problem have become worldwide topic, are subjected to people's close attention day by day.Cause under the severe day by day situation of oil price height enterprise and global environmental pollution at the traditional energy worsening shortages, development cleaning alternative energy source has been the common recognition of global various countries.Especially China, petroleum reserves is low, the external interdependency of crude oil is growing, and greatly developing alternative energy source, improving energy resource structure has been the task of top priority that ensures national energy security.
Dimethyl ether is as novel clean fuel, and development prospect is generally had an optimistic view of, and can be used as peak regulation gas, the liquid gas mixed gas of urban duct combustion gas, or the ideal fuels of diesel engine.Under current China energy availability and demand situation, dimethyl ether is the novel energy product with good development prospect, is the alternative fuel that is fit to China's energy resource structure.
Expansion along with China's dimethyl ether production and application, dimethyl ether is to outstanding the revealing of corrosion swelling problem of organic material, all there is etching problem in various degree in some sebific ducts commonly used in production reality, life-span is very short, bring potential safety hazard, increase cost, hindered the development and application of novel energy, therefore be badly in need of the special-purpose sebific duct of dimethyl ether resistant corrosion.
Summary of the invention
In order to solve the problem of sebific duct corrosion swelling in dimethyl ether production and the application process, the invention provides a kind of flexible pipe of dimethyl ether resistant corrosion, the flowing medium that is used to carry dimethyl ether He contains dimethyl ether.This tube used for dimethyl ether can be resisted the corrosion swelling action of dimethyl ether, the product that uses ripe at present production technology and equipment can conveniently produce plurality of specifications, cover Chemical Manufacture and novel energy application, raw material are easy to get, reliable performance, cost has slightly than traditional sebific duct of same specification to be increased or constant, but the life-span be multiplied, solved the technical barrier of dimethyl ether production application transmission ﹠ distribution with flexible pipe.
The present invention realizes that the technological scheme of above-mentioned purpose is: a kind of tube used for dimethyl ether, its body have three layers or multi-layer compound structure, are bonded together mutually.Internal layer is made by the organic material of dimethyl ether resistant corrosion, and can resist dimethyl ether and contain the corrosion swelling action of the flowing medium of dimethyl ether, inner wall smooth, transporting resistance is little; The middle level is one or more layers winding or braided fabric according to voltage withstand class, selects high strength organic material fiber or wire for use, can improve the compressive strength of body; Skin is made by anti-aging rubber or plastics, is protective layer, prevents the corrosive action of mechanical deterioration or external environment.
Described internal layer is by a kind of the making in polytetrafluoroethylmaterial material, polyamide material, PFPE material, hydrogenated nitrile-butadiene rubber material, the ethylene-propylene diene copolymer.The middle level is made by one or more windings or braiding in carbon fiber, polyamide fibre, terylene, acrylic fibers, polypropylene fibre, aramid fiber, the wire, and the number of plies of twining or weaving can be one or more layers.Outer by a kind of the making in sulfurized natural rubber, nitrile butadiene rubber, neoprene, polyurethane elastomer, the igelite.Interior pipe is carried the medium of blending such as dimethyl ether liquid, gas of dimethyl ether, dimethyl ether and liquefied petroleum gas (LPG), rock gas, can resist the corrosion swelling action of medium; The middle level is an enhancement layer, and the intensity of pipe is with the tolerance high pressure in improving; Skin then shields, to prevent the corrosion of mechanical deterioration and external environment.
The invention has the beneficial effects as follows that body is light, pliability good, inner pipe wall is smooth, and transporting resistance is little, and chemical-resistance is good, can resist the corrosion swelling action of dimethyl ether.The present invention can be used for the domestic gas transmission and distribution pipeline, and tank car loading-unloading vehicle flexible pipe, industry cutting welding hose, steel cylinder filling sleeve, combustion gas tool connect flexible pipe and dimethyl ether production, use each field, carries dimethyl ether or contains the flowing medium of dimethyl ether.The invention solves dimethyl ether and contain the technical barrier of dimethyl ether fluid medium transport, for condition has been created in the production application of new energy with flexible pipe.
