The present invention relates to the application method of inorganic membrane tube, duster and its production process. Inside dedusting unit, inorganic membrane tubes are arranged in tube array for purifying gas. Compared with available technology, the present invention finds one application way of inorganic membrane tube and one pollution eliminating device to polluted gas and air. The duster can separate fine dust over 0.02 micron, and may be used widely in powder recovery and treatment of high temperature smoke and other dust in iron and steel smelting, grinding material, cement plant, etc.
Description
Technical field: the present invention is a kind of application process and dust arrester and manufacture method of inorganic film tube, belong to the new and high technology that new material is applied to the environmental protection field, particularly inorganic film tube is applied in the dust arrester and the main manufacture method of this device; The device that obtains is applicable to the coal-burning boiler high-temperature smoke, Ferrous Metallurgy, and Abrasive Industry, the recovery of micro mist dirt such as cement plant is administered.
Technical background: the film separation process is the high-tech of an emerging multiple subject crossing, typical film separation process has counter-infiltration (RO), ultrafiltration (UF), micro-filtration (MF), electrodialysis (ED), infiltration gasifications (PV) etc. have been widely used in food, the beverage processing process, trade effluent is handled, extensive air separation, hydrometallurgical technology, the production of the production of gas and liquid fuel and petrochemical industry goods etc.Inoranic membrane is a kind of of solid film, be based upon inoranic membrane on the inorganic material scientific basic have polymer separation film incomparable some advantages: chemical stability is good, can be acidproof, alkaline-resisting, organic solvent-resistant; Mechanical strength is big, support inoranic membrane and can bear tens atmospheric external pressures, but and back flush; Anti-microbe ability is strong, does not have an effect with microorganism, can use in bioengineering and field of medical science; High temperature resistant, generally, reach as high as more than 800 degrees centigrade all 400 degrees centigrade of operations down; Pore-size distribution is narrow, the separative efficiency height; Inoranic membrane is widely used in and comprises food industry, medical industry, bioengineering, chemical industry, petrochemical industry etc.; Mainly comprise the purification of (air) and separating of gas component at the gas separation field, but at present successful Application only be the separation of uranium isotope, other gas purifications and separation process all are in the research.Yet there are no at present the report that inoranic membrane is used for the commercial Application for the treatment of flour dust aspect both at home and abroad.Use more cleaner both at home and abroad at present and mainly contain mechanical type cleaner, wet scrubber, electric cleaner, filtration dust catcher etc.; Development aspect sack cleaner mainly concentrates on high temperature resistant, and is wear-resistant, high flux, and in the research and development of filtrate, the while is with regard to the optimization of its purge mode and operating parameter cheaply; The development of electrostatic precipitation technology and improvement are embodied in advanced digital voltage control, wide plate spacing, the pre-lotus of wet control, flue gas conditioning intermittent power supply and the very hot attitude EFP of positive corona etc.; In addition, application and the high frequency sound wave combustion-aided dust-removing technology of the High-gradient Magnetic isolation technics (HGMS) of new development aspect flue gas ash removal strengthened the exploitation of dust-removal and desulfurizing integrated device simultaneously.Lot of domestic and international work at present all is in improvement and parameters Optimization to existing commercial Application cleaner; There are the problem of several aspects in above conventional cleaner or device: the one, the dust collector efficiency that has is low, only in certain particle size range effectively, as cyclone dust removal to just powerless less than the dust below the 5 μ m; The 2nd, high to the rerum natura requirement of dust, just require the ratio resistance of dust big as electric precipitation; The 3rd, all be lower than 150 degrees centigrade of work down usually; The 4th, investment operating cost height, electric cleaner are generally once invested needs up to ten million units; The Chinese patent communique discloses the patent No. and has been 90218313.3 and is called: the file of pottery microporous pipe filtration dust catcher patent application, and the core separation assembly that this patent adopts only is a biscuit ware, its aperture is bigger, thereby its separation accuracy is very low; And the assembling of this patent is by mechanical seal, is difficult to guarantee its air-tightness and seal complex; This pottery microporous pipe filtration dust catcher is only to effective greater than 1 micron dust.
Summary of the invention: the objective of the invention is to: application process and dust arrester and manufacture method that a kind of inorganic film tube is provided; It finds a kind of new application approach for this product of inorganic film tube, importantly is efforts at environmental protection, particularly administers for gas cleaning, air-polluting and finds a kind of effective pollution treatment device; The inorganic film tube that this device uses is to have plated a skim on the supporter of sintering, belongs to asymmetric separation assembly, and its separating mechanism is different with pottery microporous pipe filtering type, and the product separation accuracy height that provides than document is provided; Adopt silver-base solder soldering or glass solder sealing-in in addition, solved inorganic film tube and can not be connected to problem on the metal material preferably, can not only satisfy mechanical strength, bubble-tight needs, and also process for sealing is easy to realize; The dust arrester that obtains can both separate the micro mist dirt more than 0.02 micron, therefore can be widely used in high-temperature smoke, smelting iron and steel, the recovery of dust such as Abrasive Industry, cement plant and improvement and more high-class separation process.
