Abstract

The invention discloses a dot-matrix multi-thread high-temperature experiment system. The dot-matrix multi-thread high-temperature experiment system comprises a dot-matrix electric heating furnace, a plurality of groups of sample reactors, a plurality of gas paths and a plurality of gas supply devices. Wherein a plurality of heating holes are formed in the upper end of the dot-matrix electric heating furnace; each group of sample reactors comprises a plurality of sample reactors which are connected in series, metal samples are placed in cylinders of the sample reactors, air inlet and outlet pipes are arranged on top covers, valves are arranged on the air inlet and outlet pipes of the sample reactors, and the sample reactors are independently arranged in the heating holes respectively; the plurality of gas paths are connected with the plurality of groups of sample reactors in a one-to-one correspondence manner; the multiple gas supply devices are connected with the multiple gas paths in a one-to-one correspondence mode, and each gas supply device supplies different gas sources. Therefore, the system can carry out experiments under various working conditions at the same time, multiple threads can operate at the same time to complete a large number of repeated experiments, different reaction time can be controlled, experiment time is saved, experiment cost is reduced, and the system is suitable for various high-temperature experiments.

Description

technical field [0001] The invention belongs to the technical field of high-temperature corrosion experimental systems, in particular to a lattice type multi-thread high-temperature experimental system. Background technique [0002] For large-scale industrial equipment such as power station boilers, since the fuel components contain elements such as S, N, and C, the combustion products contain a certain amount of SO. 2 , SO 3 , NO, NO 2 , CO and CO 2 The further combination of these acid gases and water vapor will condense on the wall of the metal pipeline, causing metal corrosion after a long time, which is not conducive to the safe operation of large industrial equipment. Therefore, it is necessary to study the high temperature corrosion mechanism of metals. The general high-temperature corrosion test system can only carry out experiments under a single working condition, and the corrosion test generally takes more than tens of hours. If repeated verification experimen...

AI Technical Summary

Problems solved by technology

Ordinary high-temperature corrosion test systems can only conduct experiments under a single working condition, and corrosion experiments generally take more than tens of hours. If repeated verification experiments are required, the time-consuming experiments will increase exponentially, so the general ordinary experimental system has low working efficiency and It will increase other additional experimental costs and reduce the economy

[0003] Therefore, the existing high temperature corrosion experimental system needs to be improved
