Description

Technical Field

[0001] The utility model belongs to the technical field of pretreatment of online detection equipment, and in particular relates to a water adding device for a hydrogen hydrocarbon analyzer. Background Art

[0002] The three-in-one gasoline refining unit uses adsorbent to extract sulfur-containing components in catalytic gasoline, and uses a regenerator to reduce the adsorbent for recycling. The lock hopper plays a key role in the process of adsorbent sulfide reduction. Its internal media include oil, gas, hydrogen, nitrogen, and adsorbent, which switch back and forth. The pressure ranges from normal pressure to a maximum of 2.9Mpa, and the temperature is around 160°C. Therefore, it is particularly important to measure the internal gas component content of the lock hopper. At the same time, in this high temperature and high pressure environment, the internal oxygen content needs to be purged to 0 with pure nitrogen. The entire lock hopper system is carried out with the program, and the next step can only be carried out after the hydrogen hydrocarbon oxygen analyzer shows that all data meet the standards. The sample gas entering the hydrogen hydrocarbon oxygen analyzer must be filtered by water before it can reach the analysis room to prevent excessive impurities from accumulating in the analysis room and affecting the measurement accuracy.

[0003] However, during the use of this system, due to the high temperature of the sample gas, water evaporates quickly, and water needs to be added to the water filtration system every 8 hours. At the same time, the hydrogen, hydrocarbon and oxygen analyzer is installed on the sixth floor of the reaction platform. Sometimes the water level has bottomed out before 8 hours. If the time is too long, there will be too many impurities in the gas analysis room, and the measurement accuracy will decrease, resulting in the inability to run the program and the hopper system to stop operating, affecting normal production and causing certain safety hazards.
