Background technology
Heating furnace used by petrochemical field is typically all to carry out combustion heating using oil gas, and burns the waste gas for producing again
The composition for detecting its flue gas is needed just to decide whether directly to discharge before discharge.Existing detection method is typically all to adopt
With sample detecting, i.e., a ball valve is set on heating furnace, the ball valve is turned on rear and forms a thief hatch, then stored up with one
Air bag, a suction air and a wireway connect to form a simple sampling apparatus, by the wireway of sampling apparatus deeply
To in thief hatch, extruding suction air is drawn into the flue gas in heating furnace in air storage bag, so as to complete the sampling of flue gas, finally will
The fume sample of collection is chemically examined.
Existing sampling apparatus is excessively simple, as wireway can not be mated completely with ball valve, so in collection gas
When, extraneous air is easily accessible, and inaccurate so as to cause to sample, measurement result has very big error.
Utility model content
Can not fully seal with ball valve when gas is gathered and then be mixed into air for solving sampling apparatus in prior art
The inaccurate problem of sampling caused by sample, the utility model provide a kind of for flue gas of heating furnace sampling apparatus, the dress
Put by arranging the sealing and connecting device being engaged with smoke sampling mouth upper ball valve valve body in the end of intake guide, so as to perfection
Sealing problem when solving sampling, it is therefore prevented that being mixed into for outside air, improve sampling precision.
The utility model by solve the technical scheme that adopts of above-mentioned technical problem for：One kind is sampled for flue gas of heating furnace
Device, including air storage bag, suction air and intake guide, and suction air is connected with air storage bag and intake guide respectively, with by pressing
Pressure suction air makes flue gas enter in air storage bag through intake guide and suction air, and the end of the intake guide is provided with and heating
The sealing and connecting device that the smoke sampling mouth upper ball valve of stove is engaged, the sealing and connecting device include that one is fixed on intake guide end
The hollow coupling nut in portion, is provided with connecting tube, the free end of connecting tube and a hollow hold-doun nut spiral shell on hollow coupling nut
Line is detachably connected, and is provided with the connecting insertion being connected with flue gas of heating furnace thief hatch upper ball valve on hollow hold-doun nut, with
Hollow hold-doun nut is made to tighten after fixation, in connecting insertion, hollow hold-doun nut, connecting tube and hollow coupling nut with connecting tube
Form the gas production passage connected with intake guide.
The connecting tube outer shroud is cased with seal washer.
Impact bag is connected between the air storage bag and suction air.
Hand control valve I is provided between the suction air and air storage bag, is provided with hand between suction air and sealing and connecting device
Control valve II.
Beneficial effect：The utility model by arranging the smoke sampling mouth upper ball valve with heating furnace in the end of intake guide
The sealing and connecting device being engaged, the hollow coupling nut in sealing and connecting device are fixed with intake guide, hollow hold-doun nut
It is connected with ball valve coupling by connecting insertion, then hollow hold-doun nut and hollow coupling nut is connected as one with connecting tube,
So as to by the smoke sampling mouth ball valve perfect cooperation of intake guide and heating furnace, it is therefore prevented that when gas is gathered, due to ball valve with
Have ambient atmos caused by gap to be mixed in collecting sample between intake guide, generation the problems such as to ultimately result in sampling inaccurate.

Specific embodiment
As illustrated, a kind of be used for flue gas of heating furnace sampling apparatus, including air storage bag 1, suction air 4 and intake guide 6, and
Suction air 4 is connected with air storage bag 1 and intake guide 6 respectively, to make flue gas through intake guide 6 and air-breathing by pressing suction air 4
Capsule 4 is entered in air storage bag 1, and the end of the intake guide 6 is provided with and is engaged with the smoke sampling mouth upper ball valve of heating furnace
Sealing and connecting device 7, the sealing and connecting device 7 includes a hollow coupling nut 701 for being fixed on 6 end of intake guide, in
Connecting tube 705 is provided with empty coupling nut 701, and the free end of connecting tube 705 is detachable with 703 screw thread of a hollow hold-doun nut
Connection, is provided with the connecting insertion 704 being connected with flue gas of heating furnace thief hatch upper ball valve on hollow hold-doun nut 703, so that
Hollow hold-doun nut 703 is tightened with connecting tube 705 after fixing, connecting insertion 704, hollow hold-doun nut 703,705 and of connecting tube
The gas production passage 706 connected with intake guide 6 is formed in hollow coupling nut 701.
It is basic embodiment of the present utility model above, on the basis of above can be further improved, optimizes and be limited
