Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen sulfide concentration detection, in particular to a condenser device of a hydrogen sulfide detector. Background Art

[0002] During the sulfidation reaction, the waste acid sulfidation system requires the excessive addition of hydrogen sulfide and waste acid stock solution for reaction. A hydrogen sulfide gas detector is installed at the gas outlet of the reactor to monitor the concentration of hydrogen sulfide in the gas phase in real time, that is, to monitor the residual hydrogen sulfide concentration after the reaction is completed in real time to judge the degree of excess reaction. The hydrogen sulfide detector sensors currently on the market can partially automatically identify and alarm values, but the sensors may lose their function due to aging, and are prone to missing detected concentrations, affecting the real-time display and processing of on-site gas concentration information.

The gas sampling box 1 and the detector 9 are both fixed on a column 15. The condensation chamber 11 is connected to the water vapor filter 12 through a pipeline. The water vapor filter 12 is connected to the gas sampling box 1 through a pipeline. The gas sampling box 1 is connected to the detector 9 through a pipeline. A pressure regulating valve 3, a vacuum generator 5, a sampler 2 and a flow meter 4 are provided in the gas sampling box 1. The sampler 2 is provided with an air inlet and an air outlet. The air outlets are the first air outlet and the second air outlet, and the first air outlet and the second air outlet are both provided with a first one-way regulating valve 21 and a second one-way regulating valve 22. The first outlet The gas outlet is connected to the gas collecting seat 7 through the gas outlet pipe, the gas collecting seat 7 is connected to the detector 9 through the electrochemical probe 8, and the gas collecting seat 7 is also connected to the gas inlet of the flow meter 4 through the exhaust pipe. The exhaust port of the flow meter 4 is connected to the second gas outlet of the sampler 2 through a pipeline, and the second gas outlet is connected to the vacuum generator 5. The air inlet end of the vacuum generator 5 is connected to the compressed air inlet pipe 13, and the exhaust end is connected to the mixed gas exhaust pipe 14.

[0011] The working principle of this utility model:

[0012] The sampled gas with temperature enters the condensation chamber 11 through the gas sampling tube 10 and is cooled and condensed through the condensation coil to condense and remove excess moisture in the gas to be tested. The cold air in the condensation chamber 11 is provided by compressed air through the vortex cooling tube. The gas to be tested after the gas-liquid condensation separation treatment enters the water vapor filter 11 for further drying, and then enters the sampler 2, enters the gas collecting seat 7 through the first one-way regulating valve of the first gas outlet, and a small amount of gas is discharged through the second one-way regulating valve of the second gas outlet. The rest enters the gas collecting seat 7 and returns to the flow meter 4 through the exhaust pipe. The flow meter 4 can be used by the on-site workers to observe whether the flow of the gas to be tested meets the instrument requirements during inspection. If it does not meet the requirements, the gas flow can be adjusted by turning the first one-way regulating valve. After the sampled gas adjusts the flow, it enters the gas collecting seat 7 to supply the electrical chemical probe 8 for detection and transmits the signal to the detector 9 for analysis. The chemical signal is converted into a circuit signal, and then the amount of hydrogen sulfide (ppm) in the gas to be tested is fed back through the set electrical signal corresponding value. By utilizing the Venturi principle generated when the externally provided compressed air flows through the vacuum generator, negative pressure is formed at the outlet of the vacuum generator 5 to provide a power source, and the excess gas in the detector is discharged through the mixed gas discharge pipe 14.
