3.7.Device Type

The inside of the reaction vessel is under positive pressure, with a pressure<0.1MPa(Optional anti-corrosion pressure detection system, once overpressure occurs, the equipment will shut down and emit a buzzing sound).

3.8.Leakage alarm device

becauseThe gas used in the experiment is hydrogen sulfide, which is toxic, so this equipment is designed with two setsLeakage alarm deviceOne of themLocated inside the gas safety cabinet,Another design is inside the fume hoodOnce there is a leak, an automatic sound and light alarm will be triggered, and the indoor air filter will be activated. The fan inside the air filter will start to extract air from the inside of the steel cylinder cabinet for replacement, and filter it before discharge until the monitoring probe cannot detect any corrosive gas inside. The machine will shut down to ensure the safety of the user.

3.9.Gas Cabinet

4PSGas cylinder cabinet, can be placed4bottle8LThe gas cylinder

3.10.waste discharge device

A waste discharge device is designed at the end of the internal process, mainly for configuring alkaline solution. The gas is bubbled by the alkaline solution and then adsorbed by activated carbon before being discharged into the factory's waste gas pipeline (if there is no waste gas pipeline in the factory, an additional waste gas treatment tower can be installed, and after three-stage filtration, it can be discharged outdoors)

3.11.intake method

The air intake of this device adopts the method of mass flow introduction, as shown in the attached test process for details
