Abstract
The present application discloses a system and method for supplying acetylene, the system having at least one acetylene storage apparatus, a detection module, a gas dilution module and a gas supply regulating module. By mixing a feedstock stream outputted from the acetylene storage apparatus with a diluting gas in a specific ratio, a photoionization detector is successfully used to detect a solvent content in the feedstock stream. This real-time and continuous detection method ensures a stable supply of acetylene to a downstream process.
Claims10
A system for supplying acetylene comprising:
- at least one acetylene storage apparatus, for supplying a feedstock stream comprising acetylene and a solvent;
- a gas dilution module, for uniformly mixing a portion of the feedstock stream with a diluting gas according to a ratio to obtain mixed gases to be measured, the gas dilution module comprising a pressure equalization apparatus, a filtration apparatus, a flow regulating apparatus and a pre-mixing apparatus;
- a detection module, comprising a photoionization detector and a control unit, wherein the mixed gases to be measured enter the photoionization detector and are ionized by excitation, generating a measurement signal, and the control unit is configured to compute a solvent concentration on the basis of the measurement signal from the photoionization detector, make a comparison with a solvent concentration preset value, and output a control signal;
- a gas supply regulating module, comprising a solenoid valve, a pressure transmitter and a flow sensor, all of which are electrically connected to the control unit, the solenoid valve being used to switch each acetylene storage apparatus, the pressure transmitter being used to detect a pressure of the feedstock stream outputted by each acetylene storage apparatus, and the flow sensor being used to detect a flow rate of a feedstock stream supplied to an acetylene-using apparatus.
