Precision filters for analytical instruments

  Precision filters for analytical instruments summary
Precision degreasing filter is an essential filter equipment for improving the quality of gas analysis instruments such as factory or laboratory testing room
The special filter for gas analyzer developed by Zhongtai Filter Equipment Co
, Ltd
after years of experience accumulation and repeated experiments can ensure that the storage path and internal precision parts are not blocked on the premise of continuous operation of the instrument
Working principle of precision filter for analyzer
1
The gas carrying harmful substances such as dust, tar, rust and water will produce coalescence effect when entering the filter device
The larger particles will be adsorbed on the filter material, and the water will condense into larger water droplets
When entering the separation chamber, the speed of compressed gas slows down, so that the particles gather again, and the water mist condenses on a honeycomb water collector again
The water carrying impurity particles flows along the bottom to the drainage device and is discharged through an automatic or electric drainage valve
More than 95% of water droplets, oil and large particles in the gas have been filtered by the filter element, and the filtered compressed air enters the second stage filter element
When the gas passes through the second stage fiber filter screen made of special cotton, thousands of small vortices will be generated
At the same time, the compressed air will be accelerated dozens of times
The vortex center is like a tornado, forming a vacuum state
After filtering, the water droplets that have not been filtered will be gasified, replaced and filtered again
At the same time, the particles as small as 1 micron will also be completely removed by the second stage filter screen
After two-stage filtration, the clean and dry gas without dust, rust, oil and water droplets can be achieved to ensure the normal operation of the analytical instrument and prolong the service life of the equipment

Characteristics of precision degreasing filter
1
The gas precision degreasing filter integrates the functions of degreasing, desulfurization and dust removal; The pressure difference is small
2
99
9% of the oil mist can be removed, and the oil mist concentration can be locked below 0
01ppm;
3
Reasonable structure and small volume; The filter element has high-efficiency anti-corrosion performance; Large effective filtering area ensures high efficiency
4
The filter element adopts special anti leakage technology to ensure the filtering effect;
5
The inner cavity of the filter shell is anodized, and the shell is sprayed with epoxy resin dry powder;
6
The filter element adopts imported borosilicate glass fiber;
7
The fiber diameter in the equipment is small and the surface is smooth;
8
It can effectively filter solid impurities and oil mist, and quickly eliminate oil mist

application
It is mainly used for terminal filtration of various gases (including gas, gas, argon, nitrogen, helium, etc
) where the front end of analytical instruments requires high cleanliness
