Problems solved by technology

At present, the thermogravimetric analysis of microwave heating has the following problems that need to be overcome: 1) Microwaves are easy to leak, which not only causes harm to the surrounding environment and operators, but also affects the precision weighing balance; 2) Microwave pyrolysis process The temperature of the sample in the middle is difficult to measure, and the direct contact method of the thermocouple will affect the accuracy of the temperature measurement of the heated sample due to the action of the microwave on the thermocouple

Abstract

The invention relates to a thermogravimetric analysis device and method for microwave pyrolysis sludge. The device is characterized in that microwave magnetrons are arranged on two sides of a microwave oven cavity; an infrared temperature measuring probe is arranged directly above a quartz beaker, and an infrared temperature measuring instrument is connected with a computer; nitrogen in a nitrogenbottle is supplied by a quartz fine tube to the quartz beaker located in the microwave oven cavity; the upper end of a quartz bracket supported on an online weighing balance extends into a bracket channel and supports the quartz beaker; the online weighing balance is connected with the computer; the quartz bracket is sleeved with a metal shielding ring. The method comprises the followings steps:a sludge sample is put in the quartz beaker in the microwave oven cavity; nitrogen is supplied to the quartz beaker by the quartz fine tube; the microwave oven cavity is heated by the microwave magnetrons; temperature and quality data are obtained by the computer in real time. The device can prevent microwave leakage, improve measurement accuracy of the sample temperature, prevent adverse effectson the heated sample, and improve measurement accuracy of the sample temperature. Mass and temperature of the sample can be accurately measured and collected in real time with the method.

Description

technical field [0001] The invention relates to a sludge treatment device and method, in particular to a microwave pyrolysis sludge thermogravimetric analysis device and method, belonging to the technical field of sludge treatment. Background technique [0002] Sludge is an auxiliary product of water treatment, and the treatment and disposal methods mainly include landfill, agricultural use, composting, incineration, pyrolysis, etc. Among them, the pyrolysis treatment method can realize the harmlessness and volume reduction of sludge, and can obtain beneficial by-products, such as gas and oil, and the product residue can be further improved and used as activated carbon. [0003] Microwave pyrolysis sludge technology is a sludge treatment technology that has developed rapidly in recent years. Compared with conventional electric heating, it has the advantages of rapid heating, uniform heating, and good product quality, so it has received widespread attention. [0004] The hea...
