Description

Technical Field

[0001] The invention relates to the technical field of flame photometers, and in particular to a self-unloading pressure-removing moisture and dust removal device for flame photometers. Background Art

[0002] The flame photometer uses flame as an excitation light source to excite the atoms of the measured element, and uses a photoelectric detection system to measure the characteristic radiation intensity emitted by the excited element. The Model 410 produced by Sherwood is a single-channel, low-temperature flame photometer, which is used to measure the content of Na, K and Ca elements in the sample. The device has a safety device that will automatically shut down the gas pipeline when the flame is not ignited or the flame goes out during the measurement. There is also an air pressure valve. If the air pressure value is lower than a certain standard, the flame will not ignite or the flame will be extinguished. The pressure of the air source is 1kg / cm 2 (14psig), and must be clean and dry, with a flow rate of 6 liters per minute.

[0003] The existing technology mainly uses two types of air compressors, namely large air compressors and small air compressors. No matter what type of air compressor is used as the external air source, the 410 flame photometer will produce corresponding oil and condensed water according to the type of air compressor, and will also produce other impurities (such as rust particles, dust, etc.).
