Description
Technical field
The present invention relates to field of gas detection, be specifically related to the extraction detecting system of a kind of flue gas.
Background technology
In arsenic-containing gold concentrate smelting process, need the flue gas in the flue of smelting furnace to be detected, with to smelting
The control of sweetening process provides relevant foundation, and owing to containing substantial amounts of AS2O3 in detected flue gas, and production technology is in high temperature
Under high humidity height dust atmosphere, therefore in-situ type detection difficulty is very big (i.e. directly inserts detection probe in flue and carries out
Detection), and fume extraction causes when the detection device of flue peripheral disposition detects and is mostly by general draw-out device
Gas after detection is directly discharged, the most not only pollutes environment, and smoke components is complicated, A thereinSHave another name called arsenicum, belong to
Toxic element, so even carry out high-level discharging by pipeline the most easily cause the generation of security incident.Thereby it is ensured that composition is multiple
The safe and reliable detection of miscellaneous flue gas, this is extremely important for relevant enterprise.
Summary of the invention
It is an object of the invention to provide the extraction detecting system of a kind of simple in construction, flue gas easy to use.
For achieving the above object, the technical solution used in the present invention is: the extraction detecting system of a kind of flue gas, and its feature exists
In: include calorstat and trachea, in calorstat, be disposed with gas cell, and the heating list that the gas in gas cell is heated
Unit, trachea includes the gas in flue is introduced the air entraining pipe in gas cell, and the gas of gas cell is backed into cigarette
Exhaustor in feed channel, bleed is disposed with sampling probe on the body of flue, and the detection of calorstat side-walls is visited
Head is analyzed the gas componant in detected gas pond and detection signal is delivered to data processing equipment.
Use having the beneficial effects that of technique scheme generation: can ensure that flue gas by the layout of trachea and calorstat
Temperature constant, thus reduce the flue gas corrosion to equipment, it addition, back into flue gas by exhaustor again for the flue gas after detection
In pipeline, so can solve flue gas and directly arrange outward the generation of the problems such as the environmental pollution, the safety that cause.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The extraction detecting system of a kind of flue gas, as it is shown in figure 1, it includes calorstat 10 and trachea, arranges in calorstat 10
Having gas cell 20, and the heating unit 30 heating the gas in gas cell 20, trachea includes in flue A
Gas introduces the air entraining pipe 40 in gas cell 20, and the gas of gas cell 20 backs into the exhaustor 50 in flue A,
Air entraining pipe 40 is disposed with sampling probe 41 on the body of flue A, and the detection probe 60 of calorstat 10 side-walls is analyzed
Detection signal is also delivered to data processing equipment by gas componant in detected gas pond 20.Preferably, described trachea is heat tracing
Pipe, uses heat tracing pipe to carry out transfer of gas pipeline, flue gas so can be effectively ensured and be in temperature constant state, it is to avoid gas temperature
Reduce and condense on tube wall.Time actually used, gather the flue gas in flue A by sampling probe 41, and flue gas is led to
Cross in air entraining pipe 40 is delivered to gas cell 20 and carry out heated constant temperature, so can effectively guarantee that detection probe 60 detection is delivered to number
Accurate, errorless according to the flue gas information of processing means, meanwhile, by exhaustor 50, cigarette is backed into again for the flue gas after detection
In feed channel A, so can solve flue gas and directly arrange outward the generation of the problems such as the environmental pollution, the safety that cause.The present invention ties
Structure is simple, uses safety, environmental friendliness.
As further preferred version, as it is shown in figure 1, also include in described calorstat 10 being heated by heating unit 30
Warm-air pipe 80, the outlet side of warm-air pipe 80 connects the working gas inlet end of jet pump 100, the inlet end of warm-air pipe 80 and guarantor
Source of the gas connection outside incubator 10, the suction end of jet pump 100 connects the gas outlet of gas cell 20, the aerofluxus of jet pump 100
End connects the inlet end of exhaustor 50.On the one hand the layout of jet pump 100 can form subnormal ambient, it is ensured that flue gas can be smooth
Ground extracts and returns and causes in flue A, on the other hand is equivalent to be provided with vacuum environment on the pipeline of exhaustor 50, convenient
Retention flue gas in vent gas pond 20 and pipeline, it is to avoid flue gas to the damage of equipment, corrosion, also be simultaneously detection next time clearly
Altitude, in order to avoid affecting result and the precision of subsequent detection.
Preferably, as it is shown in figure 1, described heat tracing pipe also includes the anti-blowpipe 70 that sampling probe 41 carries out blowback, described
In calorstat 10, it is passed through on the pipeline of source of the gas to warm-air pipe 80 and there also is provided bypass pipe 81, the air inlet of anti-blowpipe 70 and bypass
The gas outlet of pipe 81 is connected.By the layout of anti-blowpipe 70, so termly sampling probe 41 can be carried out blowback, with in time
The air-hole blockage thing of sampling probe 41 is cleaned out by ground, thus ensures the stable operation of system.Concrete, described source of the gas is through bigeminy
Part 90 filters, reduce pressure after be passed into again in warm-air pipe 80, bypass pipe 81, by filtration, the decompressing effect of bigeminy part 90, can make
Source of the gas is purified, and guarantees source of the gas voltage stabilizing simultaneously, to avoid because of damage to the hardware such as valve or executor during source of the gas pressure fluctuations
Wound, so can be effectively ensured stablizing of flue gas environment, and then improve the stability that production equipment runs.
Further, the gas in bypass pipe 81 enters back in anti-blowpipe 70 after also passing through heating unit 30 heating, will
The source gas of blowback heats also by heating unit 30, so can ensure that air that blowback enters in flue A with
Flue-gas temperature therein is identical, thus avoids the air being blown into impact flue gas environment.
