Abstract

The invention discloses a system for rapidly analyzing pyrolysis characteristics of a solid organic matter. The system comprises a gas bottle, a mass flow rate controller, a sample injector for replacing a solid organic matter sample, a tube furnace, a condenser, a purifier, a dryer, a gas detector, a water-sealed glass bottle and a data acquisition module, wherein the gas bottle is connected with an inlet of the sample injector through the mass flow rate controller; an outlet of the sample injector is connected with an inlet of the tube furnace; an outlet of the tube furnace is sequentially connected with the condenser, the purifier, the dryer, the gas detector and the water-sealed glass bottle; the output end of the gas detector is connected with the input end of the data acquisition module; the output end of the data acquisition module is connected with a computer. According to the system, the solid organic matter sample is instantaneously heated and thermostatically pyrolyzed, so that the limitation of requirements on programmed temperature rising of a conventional pyrolysis device is overcome, the test cycle is shortened, and the test efficiency is improved.

Description

technical field [0001] The invention belongs to the field of energy-based clean utilization of renewable resources and waste, and in particular relates to a system and method for rapid analysis of pyrolysis characteristics of solid organic matter. Background technique [0002] The depletion of traditional fossil energy and the environmental pollution caused by its transformation and utilization have made clean energy technology and the transformation and utilization of renewable energy a hot topic of concern to the international community. As an important traditional fossil energy, coal is the main provider of energy on the one hand, and the main source of air pollution on the other hand. Therefore, clean coal technology is an inevitable choice for future coal utilization. As an important part of renewable energy, biomass energy is a hot spot in the development of new energy. A large amount of organic solid waste produced by industrial production and urban life, such as kit...

AI Technical Summary

Problems solved by technology

[0005] 1) As an important parameter in the study of pyrolysis kinetics, the temperature rise rate is still lower than 2°C / s in most pyrolysis studies due to the limitation of the experimental conditions of programmed temperature rise, which limits the thermal The study of the solution mechanism

[0006] 2) The experimental system mostly adopts the experimental method of first sample and then heating up. After a sample test is completed, the next test can only be carried out after the system cools down and the sample is taken out. The experimental cycle is long and the efficiency is low.

[0007] 3) The information obtained in the experiment is limited to the overall change of the reactants. The online experimental equipment using gravimetric analyzer (TG) and Fourier transform infrared spectrometer (FTIR) is high in cost, complicated in operation, small in detection amount, and also has the disadvantages of long experimental period.
