Membrane-method recovery process for realizing zero emission of volatile organic compound
ActiveCN103706224AAchieve emissionsRealize full recyclingDispersed particle separationMembrane methodOrganic solvent
The invention discloses a membrane-method recovery process for realizing the zero emission of a volatile organic compound. Waste gas which is generated by an organic compound generation system and contains the volatile organic compound directly enters a membrane separation system or is cooled and then enters the membrane separation system. A membrane can be separated by using the difference between the pressures of the upstream and downstream sides of the membrane as impelling force. Gas with high content of the volatile organic compound is obtained on the permeation side of the membrane through enrichment. Gas with low content of the volatile organic compound is obtained on the non-permeation side of the membrane. The gas with the high content of the volatile organic compound on the permeation side of the membrane enters a condensation system to directly obtain part of the organic compound. Meanwhile, uncondensed gas returns to the organic compound generation system, and the gas with the low content of the volatile organic compound on the non-permeation side of the membrane returns to the organic compound generation system. The two flows of returned gas pass through the organic compound generation system, are mixed with a part of the volatile organic compound, and re-enter the membrane separation system for next circulation. According to the process, any emitted gas is eliminated, and the zero emission is realized. The process plays an important role in recovery of an organic solvent.

The invention discloses a solid fuel pneumatic conveying heating method and system capable of controlling the content of ash combustible, wherein the method is characterized in that: at room temperature, solid fuel particles with grain size of 0 to 8mm are conveyed into a conveying section of a jetting bed combustor via a worm feeder; air and gas mixed fuel is combusted in a smoke generator when the jetting bed combustor is ignited in order to generate the smoke with the pressure from 3000 to 8000pa and the temperature from 400 to 1000 DEG C, the smoke is fed to the conveying section of the jetting bed combustor, after the combustion of the jetting bed combustor becomes stable, a smoke mixer is closed, the air at room temperature and the smoke are fed to the smoke mixer via a blower so that the oxygen content of the mixed gas is 10% to 18%; and the mixed gas carrying the solid fuel enters a combustion section of the jetting bed combustor at the speed of 9 to 15m / s, the ash combustible which is subjected to cyclic jetting combustion enters a cyclone separator to obtain solid coke and semicoke, a part of the smoke discharged by the cyclone separator enters a waste heat boiler through a dust remover for the purpose of reutilization, and another part of the smoke is fed to the smoke mixer by a circulating fan to serve as recycling smoke for controlling the oxygen content.

The invention relates to a plastic film with a layering control function and a preparation method thereof. The plastic film comprises a bonding layer, an easy-to-tear layer and a stripping layer, wherein the bonding layer is prepared from ethylene-acrylic acid copolymer or ethylene-methacrylic acid copolymer; the easy-to-tear layer is prepared from a blend formed by mixing ethylene-vinyl acetate copolymer, ethylene-methacrylic acid ionic polymer, poly-1-butene, silicon dioxide, beta-propionic acid octade, triphenyl phosphite, N,N'-ethylenebisoctadecanamide, 2,6-Di-tert-butyl-4-methylphenol, oleamide, triphenyl phosphate and oleyl palmitamide according to a certain weight ratio; the stripping layer is prepared from a blend formed by mixing ethylene-vinyl acetate copolymer, low-density polyethylene and a linear low-density polyethylene resin material according to a certain weight ratio. The plastic film with the layering control function ensures that an external sheath layer of an optical cable or an electric cable can be disengaged from the bonding layer and also ensures that a metal-plastic composite belt is free of moisture invasion.
