Traditional drop tube furnace can only be tested conventionally under single atmosphere, and furnace atmosphere is difficult to regulate, and cannot simulate pyrolysis, gasification and the burning behavior of coal dust under different atmosphere (as oxygen enrichment) condition.
Utility model content
For solving above technical problem, the utility model provides a kind of drop tube furnace air distributing device that can regulate drop tube furnace atmosphere, so that pyrolysis, gasification and the burning behavior of simulation coal dust under different atmosphere condition.
Its technical scheme is as follows:
A kind of drop tube furnace air distributing device, comprise mixed gas system, this mixed gas system comprises at least two air container, each air container is connected to mixed gas tank by separate gas mixing pipe road respectively, this mixed gas tank is communicated with drop tube furnace through supply air line, described gas mixing pipe road is provided with flow control valve, on supply air line, is connected with gas analyzer by analysis of pipeline. Adopt above technical scheme, can in drop tube furnace, pass into gas with various, so that adjusting furnace atmosphere, pyrolysis, gasification and the burning behavior of simulation coal dust under different atmosphere condition, the flow control valve arranging on gas mixing pipe road, be used for controlling each gas mixing ratio, the gas analyzer on analysis of pipeline can detect the gas passing in stove, guarantees that furnace atmosphere meets requirement of experiment.
Described supply air line is provided with flowmeter, conveniently gas flow is monitored.
Described mixed gas system is two groups altogether, two groups of air supply systems share same gas analyzer, described in two groups, on mixed gas system analysis of pipeline separately, be equipped with pipe valve, based on said structure, can adopt secondary plenum system to carry out air feed, in the time that first group of mixed gas system air demand cannot meet requirement of experiment, supplement by second group of mixed gas system, improve system reliability, meanwhile, two groups of mixed gas systems share same gas analyzer, have simplified pipeline structure, make entire system compacter, and saved experimental cost.
As preferably, described mixed gas tank comprises inlet chamber and mixed air cavity, between this mixed air cavity and inlet chamber, be provided with dividing plate, on described dividing plate, be distributed with mixed gas mesh, mixed air cavity is communicated with inlet chamber, inlet chamber is communicated with corresponding gas mixing pipe road, in mixed air cavity, be provided with the conduit being communicated with supply air line, experimental gas is entered in inlet chamber by gas mixing pipe road, flowing into mixed air cavity through mixed gas mesh fully mixes, enter in supply air line by conduit again, mist is entered in stove equably, be convenient to furnace atmosphere to control.
For further ensureing gas mixed effect, mixed gas tank entirety is the cylindrical-shaped structure of vertical setting, and mixed air cavity is upper, inlet chamber under.
As preferably, described mixed gas tank adopts the transparent materials such as glass or acrylic board to make, so that Real Time Observation gas mixes situation.
Beneficial effect:
Drop tube furnace air distributing device of the present utility model, can regulate drop tube furnace furnace atmosphere easily so that pyrolysis, gasification and the burning behavior of simulation coal dust under different atmosphere condition, have simple in structure, good reliability, the advantage such as easy to operate.
