Problems solved by technology

[0005] At present, most of the treatment of self-adhesive waste at home and abroad is to consider incineration and landfill, but with the improvement of ecological environmental protection level, self-adhesive waste gradually begins to avoid incineration and deep burial, basically in the state of stockpiling Preservation not only takes up valuable land resources, but also seriously pollutes the environment and causes a waste of resources

specific Embodiment approach 1

[0026] After crushing the self-adhesive waste 101, add 100g of the crushed self-adhesive waste 103 into the pyrolysis reactor through the feeder, start heating to the pre-pyrolysis temperature of 260°C, and after the pre-pyrolysis reaction time is 0.1h Afterwards, continue to heat up to the pyrolysis temperature of 650° C., and control the pyrolysis reaction time to 1 h. The pre-pyrolysis reaction product was condensed by a condensation tower to obtain 15.23 g of water 105 , and the pyrolysis product was condensed by a condensation tower to obtain 28.90 g of pyrolysis gas 115 , 9.28 g of pyrolysis water 123 and 23.40 g of pyrolysis oil 121 . Through pyrolysis, the conversion rate of self-adhesive waste raw materials is 76.81%, which well achieves the purpose of reducing solid waste; the yield of pyrolysis oil 121 reaches 23.40%, and the density is 0.963g / ml. The heat reaches 32.93MJ / kg.

specific Embodiment approach 2

[0028] After the self-adhesive waste 101 is crushed, add 100g of crushed self-adhesive waste 103 into the pyrolysis reactor through the feeder, start heating to the pre-pyrolysis temperature of 240°C, and after the pre-pyrolysis reaction time is 1h , continue to heat up to the pyrolysis temperature of 650°C, and control the pyrolysis reaction time to 1h. The pre-pyrolysis reaction product was condensed by a condensation tower to obtain 13.49 g of water 105 , and the pyrolysis product was condensed by a condensation tower to obtain 29.80 g of pyrolysis gas 115 , 11.10 g of pyrolysis water 123 and 22.45 g of pyrolysis oil 121 . Through pyrolysis, the pyrolysis conversion rate of self-adhesive waste raw materials is 76.84%, which well achieves the purpose of solid waste reduction; the yield of pyrolysis oil 121 reaches 22.45%, and the density is 0.965g / ml , the calorific value reaches 32.87MJ / kg.

specific Embodiment approach 3

[0030] After the self-adhesive waste 101 is crushed, add 100g of crushed self-adhesive waste 103 into the pyrolysis reactor through the feeder, start heating to the pre-pyrolysis temperature of 120°C, and after the pre-pyrolysis reaction time is 1h , continue to heat up to the pyrolysis temperature of 650°C, and control the pyrolysis reaction time to 1h. The prepyrolysis reaction product was condensed by the condensation tower to obtain 13.10 g of water 105 , and the pyrolysis product was condensed by the condensation tower to obtain 29.84 g of pyrolysis gas 115 , 11.48 g of pyrolysis water 123 and 21.62 g of pyrolysis oil 121 . Through pyrolysis, the conversion rate of self-adhesive waste raw materials was 76.04%, which achieved the goal of solid waste reduction; the yield of pyrolysis oil 121 reached 21.62%, and the density was 0.946g / ml. The heat reaches 32.20MJ / kg.

Abstract

The invention provides a method for preparing fuel oil through pyrolysis of waste non-setting adhesives. The method comprises the following steps: (1) crushing the raw material waste non-setting adhesives, then placing the crushed waste non-setting adhesives in a pyrolysis reactor carrying out heating to a pre-pyrolysis temperature in a pre-pyrolysis time period and then carrying out pre-pyrolysis so as to obtain a pre-pyrolysis product; (2) carrying out heating to a pyrolysis temperature in a pyrolysis time period and then carrying out pyrolysis so as to obtain pyrolysis products, wherein the pyrolysis products comprise pyrolysis liquid and pyrolysis gas; and (3) subjecting the pyrolysis liquid to distillation so as to obtain pyrolysis oil of different fractions.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to a method for preparing fuel oil by pyrolyzing self-adhesive waste. Background technique [0002] The characteristics of energy resource endowment of "rich in coal, low in oil, and poor in gas" have shaped my country's long-term energy consumption structure dominated by coal, and objectively caused the tension in the supply of crude oil and natural gas. In 2013, my country's crude oil output was about 210 million tons, an increase of 2.1% over the previous year. Nevertheless, crude oil imports still exceeded 280 million tons, and the dependence on foreign crude oil reached 58.1%; natural gas imports were 53 billion cubic meters, and the dependence on foreign Reached 31.6%. It is expected that with the further development of the national economy, my country's dependence on foreign countries for crude oil and natural gas will continue to increase. Obviously, the d...
