Problems solved by technology

[0019] In the above-mentioned documents and other prior art, although there are some separation methods about grease or hydrocarbon fuel and water, however, the bio-oil obtained by high-temperature distillation and carbonization of garbage is quite different from ordinary grease 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 membrane separation method, the separation efficiency is 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

[0082] 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 (1). The triblock copolymer shown. Polyvinylidene fluoride and triblock copolymer shown in formu...

Embodiment 2

[0084] Select municipal solid waste from the garbage compression and transfer station in Haidian District, Beijing, and carry out high-temperature distillation carbonization on the above-mentioned garbage through the following steps: (1) put the garbage into the garbage transportation device; (2) pass the garbage transportation device through the high-temperature distillation (3) take out the gas stream of crude bio-oil and water vapor from the upper part of the high-temperature distillation carbonization device; (4) make the gas stream pass through the catalyst bed in gaseous form; (5) condense the effluent from the catalyst bed, Obtain the mixture of upgraded bio-oil and water; (6) Obtain charcoal materials from the garbage transport device passing through the 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 35...

Abstract

The invention provides an integrated garbage treatment method which comprises the steps that garbage is subjected to high-temperature distilling and carbonization, so that a gas stream containing crude bio-oil and vapour is obtained; the gas stream is hydrotreated, and the crude bio-oil in the gas stream is upgraded; and the hydrotreated gas stream is made to condense, and upgraded bio-oil is obtained through a membrane separation method. By adoption of the integrated garbage treatment method, the high-quality bio-oil can be obtained, and accordingly the comprehensive benefits of the integrated garbage treatment method are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, in particular relates to a comprehensive treatment method for garbage, and more particularly relates to a garbage resource treatment method capable of obtaining high value-added products. 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] If these wastes cannot be properly treated and disposed ...
