Problems solved by technology

[0020] In the above-mentioned documents and other existing technologies, although there are some methods for separating oil or hydrocarbon fuel from water, the bio-oil obtained by high-temperature distillation and carbonization of garbage is quite different from ordinary oil or hydrocarbon substances, even in After hydrogenation and upgrading treatment, its composition is still very complex. Compared with oil or hydrocarbon fuel, the number of components is several times more, and there are also many polar components, which are very easy to form an emulsion with water. This emulsion is in When using ordinary membrane separation system, the separation efficiency is usually relatively low, for example, it is difficult to separate effectively and the separation flux is very low (that is, the flow rate is low)

Embodiment 1

[0092] Prepare the separation membrane by the following method: the first monomer (3.5 parts by weight) shown in the above formula (2), the second monomer (0.726 parts by weight) shown in the above formula (3) and AIBN (0.045 parts by weight) The mixture is dissolved in the DMF solution, the concentration of the mixture in the DMF solution is 0.3g / mL, then the reaction system is deoxygenated (preferably deoxygenated by freeze-thaw cycles), and then the reaction system is sealed and heated to React at 80°C for 30 hours under stirring. After the reaction, methanol is added and exposed to air to terminate the polymerization reaction. Then add cold methanol that is 2 times the volume of the reaction system and ethyl acetate-petroleum ether (the volume ratio of the two is 1:4) mixture that is 1 time the volume of the reaction system to precipitate, filter, and dry to obtain the formula (3). The triblock copolymer shown. Polyvinylidene fluoride and triblock copolymer shown in formu...

Embodiment 2

[0094] Select domestic waste from the waste compression and transfer station in Haidian District, Beijing, and carry out high-temperature distillation carbonization on the above-mentioned waste through the following steps: (1) put the waste into the waste transport device; (2) pass the waste transport device through the high-temperature distillation carbonization (3) take out the gas flow of crude bio-oil and water vapor from the upper part of the high-temperature distillation carbonization device; (4) make the gas flow pass through the catalyst bed in gaseous form; (5) condense the effluent from the catalyst bed to obtain A mixture of upgraded bio-oil and water; (6) Obtaining charcoal materials from a garbage transport device passing through a high-temperature distillation carbonization device. The high-temperature distillation carbonization device is heated by high-temperature oxygen-free steam, the temperature of the high-temperature oxygen-free steam is 350°C, the nitrogen ...

Abstract

The invention provides a separation system for garbage resourceful treatment. The separation system comprises a membrane assembly, wherein the membrane assembly comprises a separation membrane based on polyvinylidene fluoride. The separation system can effectively separate bio-oil obtained from distilling and carbonizing garbage in high temperature from water.

Description

technical field [0001] The invention belongs to the technical field of separation, and in particular relates to a separation system for waste resource treatment. Background technique [0002] With the rapid development of the economy and the continuous acceleration of the urbanization process, the number of cities and the size of the city are also constantly changing and expanding. Due to the sharp increase in the resident population and urban area in the city, the total amount of urban domestic waste will increase accordingly. increase in magnitude. It is predicted that by 2030, the annual output of municipal solid waste in China will reach 409 million tons. Large and medium-sized cities, especially megacities, have relatively high per capita waste generation, with a growth rate of around 20%. [0003] At present, garbage disposal is generally through incineration to reduce the garbage capacity. The incineration treatment method will produce dioxins and other pollutants ...
