Abstract
The utility model relates to a sampling device of sulfur trioxide in flue gas, which comprises a sampling outer tube and a sampling inner tube. The sampling outer tube is a stainless steel casing, and the sampling inner tube is a quartz glass inner tube. A quartz glass sampling nozzle is arranged at the head of the inner tube. The outer surface of the inner tube is coated with inner tube cushion materials. A flue gas lead-out interface is arranged at the tail of the sampling device. A high power heating rod is arranged between the sampling outer tube and the sampling inner tube. The sampling device of the sulfur trioxide in the flue gas disclosed by the utility model can avoid the sulfur trioxide from dewing in a sampling system, so that the sulfur trioxide content in the flue gas can be measured accurately.
Description
Technical field
The utility model relates to flue gas sampling, measuring technique, particularly a kind of flue gas sulfuric anhydride (SO
3) sampler.
Background technology
To the sampling of sulfuric anhydride, all adopt much at one form and method both at home and abroad.Stopple coupon is inside and outside two-layer pipe, and outer tube is a metal pipe material, and interior pipe is a glass.For preventing SO
3Dewfall in sampling system, interior pipe need be heated to more than the flue gas dew point temperature.
General sampling system exists following point at present:
1, because stopple coupon need be worked in 320 ℃～420 ℃ temperature ranges, and duty is just as a semi-girder, and there is degree of disturbing more greatly the end, interior pipe is broken easily.
2, the not enough even not heating of heating power makes SO
3Dewfall in sampling system, the accuracy that influence is measured.
Summary of the invention
Task of the present utility model provides a kind of flue gas sulfuric anhydride sampler, and it has solved above-mentioned existing in prior technology problem, has reached and has avoided SO
3Thereby dewfall is measured SO in the flue gas exactly in sampling system
3The purpose of content.
Technical solution of the present utility model is as follows:
A kind of flue gas sulfuric anhydride sampler, it comprises pipe in sampling outer tube and the sampling, described sampling outer tube is a stainless steel outer sleeve; Pipe is pipe in the quartz glass in the described sampling, at interior tube head quartz glass sampling mouth is set, pipe buffering bedding and padding in interior tube outside coats;
The afterbody of described sampler is provided with flue gas and draws interface;
Adopt high-power heating rod between the pipe in described sampling outer tube and the sampling.
The rear portion of described sampling outer tube is provided with temperature control lead-in wire port.
The external temperature controller of described high-power heating rod.
Described high-power heating rod controllable temperature keeps 〉=and 250 ℃.
The dimensions of described sampling outer tube is ￠ 40 * 2500cm.
The dimensions of pipe is ￠ 18 * 2700cm in the described quartz glass.
Flue gas sulfuric anhydride (SO of the present utility model
3) key component of sampler is sampling part, has following characteristics after improving:
1, the sampling outer tube adopts the on-deformable exotic material of ￠ 40 * 2500cm, and pipe adopts ￠ 18 * 2700cm quartz glass in the sampling, and in guaranteeing by particular design pipe glass at outer tube trouble free service under the degree of disturbing greatly.
2, the powerful heating rod of employing between sampling outer tube and the interior pipe, controllable temperature (external temperature controller) keep 〉=and 250 ℃.
Description of drawings
Accompanying drawing is the structural representation of a kind of flue gas sulfuric anhydride sampler of the present utility model.
Reference numeral:
1 is quartz glass sampling mouth, and 2 be pipe in the quartz glass, and 3 be stainless steel outer sleeve, and 4 be that interior pipe cushions bedding and padding, and 5 draw interface for flue gas, and 6 is that temperature is controlled the port that goes between.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to accompanying drawing, a kind of flue gas sulfuric anhydride sampler of the present utility model is equipped with pipe in sampling outer tube and the sampling, and the sampling outer tube is a stainless steel outer sleeve 3, and pipe is pipe 2 in the quartz glass in the sampling.
Tube head is provided with quartz glass sampling mouth 1 in sampling.Pipe buffering bedding and padding 4 in the tube outside coats in sampling.The afterbody of sampler is provided with flue gas and draws interface 5.
The rear portion of sampling outer tube is provided with temperature control lead-in wire port 6.The dimensions of sampling outer tube is ￠ 40 * 2500cm.The dimensions of pipe is ￠ 18 * 2700cm in the quartz glass.
Adopt high-power heating rod between the pipe in sampling outer tube and the sampling.The external temperature controller of high-power heating rod, controllable temperature keep 〉=and 250 ℃.
In sum, adopt flue gas sulfuric anhydride sampler of the present utility model, can avoid SO
3Thereby dewfall is measured SO in the flue gas exactly in sampling system
3Content.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim the variation of the foregoing description, modification etc.
