A tester and method for producing flammable gas when a substance is wet

Abstract

The invention provides a tester and a method for detecting combustible gas generation of a substance in wet, belonging to the field of environmental protection technology. The tester comprises a bracket with a lifting rocking handle, a reaction kettle, a reaction kettle thermal resistor, a rotary charging device, a charging tray, a raw material tank, a heating device, a heater thermal resistor, a pressure sensor, a positive pressure pump, a vacuum pump, a charging pump, a flowmeter, a positive pressure electromagnetic valve, a negative pressure electromagnetic valve, an exhaust electromagnetic valve, a charging electromagnetic valve and a control part. In the tester, before reaction, initial parameters of the reaction need to be regulated, then the rotary charging device carries out charging, and thus the influence of early charging on reaction excess detection is avoided; in the invention, by adopting the double-layer quartz glass reaction kettle, the reaction phenomena can be observed in real time; the reaction kettle is matched with a metal base and sealed by a flange structure, and relatively high positive and negative pressures can be borne while air tightness is guaranteed; and in the invention, the gas generation law of a substance reacting in water is accurately and conveniently explored, a promotion or inhibition method is studied, and related reaction mechanism is clear.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a tester and a method for producing combustible gas when a substance is wet. Background technique [0002] Some substances in industrial production can produce gas when wet, such as calcium carbide reacting with water to produce acetylene gas, metal aluminum powder reacting with water to produce hydrogen gas; some of the produced gas can be used in industrial production and has economic benefits. Some are by-products of the process, which are toxic and harmful to the human body and can cause environmental pollution. In addition, in the field of hydrogen energy, a key research direction in recent years is the reaction of aluminum powder and water to produce hydrogen. Hydrogen energy has high calorific value and environmental protection. Features, it can be used as a power source for underwater vehicles or portable batteries. [0003] At this stage, th...

Some are by-products of the process, which are toxic and harmful to the human body and can cause environmental pollution; in addition, in the field of hydrogen energy, a key research direction in recent years is the reaction of aluminum powder and water to produce hydrogen, hydrogen energy has high calorific value and environmental protection. Features, can be used as a power source for underwater vehicles or portable batteries

[0003] At present, there is no relevant equipment to study the gas produced by substances when they are wet. The existing simple experimental devices have poor measurement accuracy, cumbersome operations and all need to be done manually. It is impossible to judge when the test can be stopped due to the progress of the reaction; and it can only be detected for a certain substance, and the detection range is very limited
