Background technology
During traditional industry production application, two kinds of gases need mixing or hybrid switching that gas is usually used when reacting
Blender.Existing gas mixer is usually to be passed through two kinds of gases simultaneously in a vessel, then by between gas
Diffusion motion carries out free mixing, and this gas mixing mode has not fully slow with uniform, mixing velocity enough the deficiency of mixing；
Carrier gas is entered in breather with sample gas, and the two is difficult to be sufficiently mixed in the short time, while the mixing temperature of sample gas can not be fast
Speed is lifted to more than dew point, can be condensed in the inwall of breather, so as to cause flue dust to pile up, is caused to measuring sample gas components concentration
Deviation.
Or by collection feeler lever inside place heater strip come by way of heating sample gas, make sample temperature degree reach dew point with
On, but later maintenance is not easy to using the method.
A kind of number of patent application gas mixer that has been 201310448853.7 disclosure of the invention, the invention pass through two skies
Bulbus cordis and the connection of necking enlarging pipeline, using the change of pressure, realize the mixing of gas.But the device is not particularly suited for dust
In instrument field, and hollow ball is not easy to be cleaned.
A kind of number of patent application gas mixer that has been 201210137582.9 disclosure of the invention, the invention is by making to be mixed into
Gas is increased by one group of spreader shape air inlet pipe its pressure no less than 4 rapidly, then from multiple different azimuths enter main enter
Mix with mainstream gas in trachea, so that two kinds of gases reach the rapid purpose for mixing.The apparatus structure is complicated, and inconvenience
In dismounting and cleaning parts.
Content of the invention
This utility model aims to overcome that the sample gas gathered by the gas collecting device of dust instrument can not be fast with carrier gas
The problem of fast mix homogeneously, this utility model provide the gas sampling assembly that a kind of gas quickly mixes, and make carrier gas and sample gas
Quickly it is sufficiently mixed, sample temperature degree is rapidly achieved more than dew point.
It is as follows using solution that this utility model solves above-mentioned technical problem：A kind of quick mix homogeneously sample gas and dilution
The gas collecting device of gas, the device include：Gooseneck, fluidized bed mixer, feeler lever cavity, breather, flange, graphite grazing pad

Graphite sealing gasket is provided with port；The other end of feeler lever cavity is connected and flange and is provided with diluent air import；Breather is worn
Cross at the axle center of flange and stretch in feeler lever cavity；The air-flow for being provided with cylinder-like structure between breather and gooseneck mixes
Device；Described breather is imported in fluidized bed mixer, is provided with aperture on described fluidized bed mixer.
Further, fluidized bed mixer inwall arranges a diameter of 18-30mm, the screw thread that pitch is 2～3mm.
Further, 4～8 apertures are provided with according to airflow requirement on the tube wall of fluidized bed mixer, 3～5mm of hole diameter,
Threadingly direction is opened in blender outer wall aperture, is divided to two both sides for coming fluidized bed mixer to be uniformly distributed.
Further, asbestos seal gasket is provided between feeler lever cavity and fluidized bed mixer.
Further, gooseneck is bolted on feeler lever cavity.
Further, flange is bolted on feeler lever cavity；Close with asbestos washer between feeler lever cavity and flange
Envelope.
Further, the flange that the flange welded by its end of breather is connected with feeler lever cavity is with bolt connection.
This utility model is compared with following remarkable advantage relative to prior art：
(1) this utility model is by arranging the spiral lines on fluidized bed mixer on the aperture and fluidized bed mixer of both sides altogether
With the air intake installation of composition, diluent air is entered fluidized bed mixer by the aperture on fluidized bed mixer and is quickly mixed with sample gas.
The device simplifies the gas mixer in existing dust instrument gatherer process, it is ensured that in dust gatherer process, outlet stablizes
Property, while improve the efficiency of gas mixing.
(2) this utility model is easy to assembly, and fluidized bed mixer individually can be dismantled, and be easy to the cleaning of part.
(3) this utility model overall construction design is reasonable, structure is relatively simple, cost is relatively low.
