Thermogravimetric characteristic analysis system for massive test specimen supercritical water gasification

Abstract

The invention discloses a thermogravimetric characteristic analysis system for massive test specimen supercritical water gasification. The system comprises an electronic balance, a main reaction kettle and a heating furnace, wherein a material bucket is suspended in the main reaction kettle; the material bucket is suspended at one end of the electronic balance, and a balancing bucket is suspended at the other end of the electronic balance, and is connected with a computer; the main reaction kettle and the heating furnace are sealed bodies. The system also comprises an inert gas source connected with the main reaction kettle, a high-pressure pump and a de-ionized water storage tank, wherein de-ionized water enters the high-pressure pump, and enters the main reaction kettle after being pressurized; the material bucket is made from a steel wire mesh. According to the system, the shortcoming that thermogravimetric characteristic analysis and researches can be made by a conventional device only under a normal pressure condition is overcome; in addition, thermogravimetric experimental researches on a supercritical water gasification process of a massive test specimen (being more than 100 grams) can be made, and equipment technologies for organic solid waste gasification reaction mechanisms and kinetic researches are expanded.

Description

Technical field [0001] The invention relates to a system and key device for analyzing the thermogravimetric characteristics of supercritical water vaporization, in particular to a system for analyzing the thermogravimetric characteristics of a large amount of material sample during the supercritical water vaporization process. Background technique [0002] Thermogravimetric analysis is an important method to study material characteristics and reaction laws. At present, thermogravimetric analysis usually uses a thermobalance, which is characterized by the use of electric heating samples. Generally, only trace materials of about 5-10 mg can be analyzed. The thermogravimetric data obtained by this method cannot be fully reflected. The change characteristics of the material when the actual amount of material is large; another typical analysis method is the thermogravimetric analysis of the microwave heating of the large amount of material sample, which makes up for the shortcomings t...
