Embodiment 1

[0111] Dissolve 5 parts of block polyether amide copolymer (Pebax2533 for the grade) in 40 parts of isopropanol, heat and stir, control the temperature at 80°C, and heat for 5 hours to form a sol solution. Weigh 5 parts of nanocrystalline SiO2 (particle size range 20-40nm) solid, dissolve it in 10 parts of isopropanol, stir and mix evenly, add it dropwise into the mixed sol, and stir for 30 minutes to obtain a nanocrystalline SiO2 polymer mixed solution. 30 parts of polyacrylonitrile carbon fibers were impregnated with the nanocrystalline SiO2 polymer mixed solution, and pulled out at a rate of 5 cm / min. The modified carbon fibers were dried at 80° C. for 12 hours. Then high temperature treatment at 1300°C for 3h in Ar atmosphere. The TEM picture of the carbon fiber that present embodiment obtains is as figure 1 shown.

Embodiment 2

[0113] Dissolve 20 parts of polyetheramide copolymer (Pebax3533 for the grade) in 20 parts of isopropanol, heat and stir, control the temperature at 80°C, and heat for 12 hours to form a sol solution. Weigh nanocrystalline SiO 2 (Particle size range 40-100nm) 20 parts, dissolved in 10 parts of isopropanol, stirred and mixed evenly, added dropwise to the mixed sol, stirred for 30 minutes to obtain nanocrystalline SiO 2 Polymer mixed solution. 10 parts of polyacrylonitrile carbon fibers were impregnated with the nanocrystalline SiO 2 The polymer mixed solution is pulled out afterward, and the extraction speed is 20cm / min. Dry the modified carbon fiber at 80°C for 12h. Then it was treated at 1500°C for 10h in an Ar atmosphere. The TEM picture of the carbon fiber that present embodiment obtains is as figure 2 shown.

Embodiment 3

[0115] Dissolve 5 parts of polyether amide copolymer (Pebax7233 for the grade) in 40 g of tetrahydrofuran, heat and stir, control the temperature at 80°C, and heat for 5 hours to form a sol solution. Weigh nanocrystalline SiO 2 (Particle size range 100-300nm) 5 parts, dissolved in 20 parts of tetrahydrofuran, stirred and mixed evenly, added dropwise into the mixed sol, stirred for 30 minutes, to obtain nanocrystalline SiO 2 Polymer mixed solution. 50 parts of polyacrylonitrile carbon fibers were impregnated with the nanocrystalline SiO 2 The polymer mixed solution is pulled out afterward, and the extraction speed is 5cm / min. Dry the modified carbon fiber at 80°C for 12h. Then high temperature treatment at 1300°C for 10h in Ar atmosphere. The TEM picture of the carbon fiber that present embodiment obtains is as image 3 As shown, the XRD pattern is as Figure 4 shown.

Abstract

The invention discloses a treatment method of high-salt solid waste containing organic matters; the treatment method comprises the following steps of: conveying high-salt solid waste containing organic matters to an incinerator for incineration, wherein the incineration temperature is 1000-1300 DEG C; generating waste smoke and salt after incineration; through an exhaust gas treatment process, theseparated CO2 gas of the waste smoke enters an alkali making process for recycling; the waste salt can obtain saturate sodium chloride solution by a waste salt treatment process to enter alkali making reaction for recycling; the heat in the waste smoke and waste salt is supplied to power generation through a part of the smoke heat exchanger and the waste salt heat exchanger, and the other part isused for alkali production reaction. The treatment method provided by the invention can treat the high-salt solid waste containing organic matters by an incineration method; the high-salt solid wastecontaining organic matters can be subsequently converted into a series of chemical productsAt the same time, the heat generated by the incinerator is used for supplying each application section during the whole process, and the whole process is energy-saving and efficient.

Description

technical field [0001] The invention relates to the field of solid waste treatment, recovery and reuse, in particular to a treatment method for high-salt solid waste containing organic matter. Background technique [0002] At present, the scale of industrialization continues to expand, and the output of various chemical products such as pesticides, medicines, and chemical fibers is increasing year by year, and the industrial waste is also increasing year by year. Most of this kind of industrial waste is high-salt solid waste containing organic matter. The content of sodium salt in the waste salt is high, the industrial conversion rate is low, and the recovery rate is low. It is difficult to effectively treat this type of waste salt. [0003] The incineration method is a high-temperature heat treatment technology that effectively treats waste salt. Excessive oxygen and waste salt undergo a sufficient oxidation and combustion reaction in the furnace, so that the toxic and harm...
