Working principle:
Pressurized combustible gas and pressurized air (or other flammable gas) enter their respective pressure regulating valves from the two inlet of the mixer. The air pressure regulating valve is the active valve, and its set pressure is the working pressure of the mixer (usually 0.03-0.2mpa adjustable). The LPG pressure regulating valve is the following valve. The set pressure is the same as the air pressure and can follow the fluctuation of the air pressure at any time to ensure that the two gases enter the mixing valve at basically the same pressure.
Oxygen content analyzer or calorific value meter signal is usually introduced into the interlocking loop, so that when the mixing ratio is out of tolerance, the mixing machine can be automatically cut off. In order to ensure safety, the mixer enters the self-locking state after emergency cutting, which must be manually started by the operator after troubleshooting.
High pressure proportional mixer has the performance of automatic tracking user flow, so there is usually no need to set large gas tank or storage tank buffer equipment between the mixer outlet and the external pipe network. The mixing proportion of high pressure proportional mixer can be easily adjusted within the allowable safe mixing range, and adjusted to manual mode, but it can also be equipped with explosion-proof control motor to achieve automatic control according to user requirements.
Hydrogen mixing unit
Hydrogen has the characteristics of fast combustion speed, wide combustion boundary, small specific calorific value, long quenching length and so on. Adding hydrogen into natural gas can change the combustion characteristics of natural gas. Hydrogen-doped natural gas can be used directly, or hydrogen and natural gas can be used separately. Hydrogen-doped natural gas is mainly used as commercial or civil gas fuel. Meanwhile, with the development of hydrogen fuel cell vehicle industry in the future, the problem of large-scale transportation of hydrogen energy can be solved.
Working principle and features:
Use advanced online dynamic regulating hydrogen blending ratio and measurement control technology, by controlling the input parameters, combined with the flow, temperature, pressure, component tester and synergy to adjust gas and hydrogen gas into the air, realize the mixing proportion of hydrogen adjustable online, according to the coarse tuning the hydrogen flow rate, gas flow rate by using mixed gas hydrogen content percentage of fine adjustment mixing amount of hydrogen. The constant ratio mixing and follow-up control of natural gas and hydrogen are realized by using the mixing equipment with constant ratio flow control system. The unique static mixer mixing module and the combination of high quality components ensure the safety accuracy, feedback speed and mixing uniformity of gas hydrogen mixing equipment.
