Description
Technical field
The utility model relates to the petrochemical technology field, particularly a kind of flue gas sampling specific purpose tool.
Background technology
For understanding high-temperature gas component and content in the flue, need take a sample, chemically examine the high-temperature gas in the flue.The Chinese patent notification number is the patent of CN2602361Y, discloses a kind of multiple spot flue gas cigarette taking out device.Its objective is provides a kind of collection multiple spot flue gas, makes sampling have more representativeness, and analysis data is more true and reliable.Also have a kind of flue gas sampler, what its sample tap connected mode adopted is ball face sealing structure, and sealing effectiveness is undesirable, and its ball face sealing point loses sealing effectiveness because of the corrosion of medium reason after a period of time, and sphere and concave spherical surface difficulty of processing are big.In addition, must take off when sampling finishes the post-sampling pipe, not so sampling pipe will stop up.When unloading sampling pipe,, safety is caused a hidden trouble because the flow velocity of catalyzer flue gas stream is fast.Whole structure is undesirable, causes deficiencies such as sampling difficulty, gas leakage.Install, the fixing unreasonable structure of filter cylinder, it is not tight to cause filter cylinder to be fixed, and makes sampling analysis out of true as a result.
The utility model content
The purpose of this utility model is: a kind of flue gas sampling tube is provided, changes the structure of flue gas sampler, improve the reliability of sampling, make the result of analysis more accurate; In addition, flue gas sampling tube fitting operation is easier.
The technical solution adopted in the utility model is: the flue gas sampling tube, mainly form by rapid-acting coupling, sealing adaptor, cover, sampling cylinder, filter cylinder lid, filter cylinder chuck, filter cylinder, sampling cylinder lining and nut, it is characterized in that: sampling cylinder is the circular cylinder that the end is arranged, the sampling cylinder bottom has center pit, nut to be welded on the outer face, bottom of sampling cylinder; A cylindrical shape sampling cylinder lining is arranged in sampling cylinder, and the sampling cylinder sleeve is porose, sampling cylinder sleeve hole, sampling cylinder bottom centre hole and nut center pit UNICOM; An annular filter collet chuck cover is arranged in sampling cylinder and at the top of sampling cylinder lining, and the endoporus of filter cylinder chuck is conical, and it is that conical bottom is the filter cylinder of circular arc that a top is arranged in the conical hole of filter cylinder chuck; Screw thread is fixed with cover in the upper end of sampling cylinder, is fixed with the filter cylinder lid in the cover inside center, and the bottom of filter cylinder lid is a truncated cone, and filter cylinder builds the frustum of a cone of bottom in the filter cylinder upper port, and the filter cylinder upper end is pressed in the round taper hole of filter cylinder chuck.Filter cylinder is stamped center pit; Welded top at cover has sealing adaptor, and sealing adaptor has center pit; Be connected with a rapid-acting coupling in the end of sealing adaptor.
Filter cylinder is made by corrosion resistant plate.
Filter cylinder lid, filter cylinder chuck and sampling cylinder lining adopt polytetrafluoroethylmaterial material to make.
The beneficial effects of the utility model: the utility model flue gas sampling tube, the structure of change flue gas sampler can improve the reliability of sampling; In addition, flue gas sampling tube fitting operation is easier.
