Description
Technical field:
The present invention relates to the flue gas preprocessor of the quick environmental protection of a kind of ne-leakage.
Background technology:
At large industry equipment run durations such as station boiler, Industrial Boiler and smelting furnaces, in order to grasp equipment
Actual state, needs that its high-temperature flue gas is carried out composition and accurately measures.Due to high-temperature flue gas have temperature high,
The shortcomings such as dust burdening is big, before stove cigarette enters flue gas analyzer measurement, it is necessary to through the pre-sampler of flue gas, right
Stove cigarette carries out filtering, condense and dehumidifying, it is ensured that flue gas analyzer is safely and accurately measured.
Having various flue gas preprocessor both at home and abroad, basic structure is the most as shown in Figure 1.This conventional junction
The flue gas preprocessor of structure has the most several defect:
1), after the air pump in tradition flue gas preprocessor structure is all disposed within filtration core and condenser, so lead
When causing air pump work, it is negative pressure in flue, filtration core and the condenser before air pump, if these
Link is the most poorly sealed, results in air and leaks in flue gas preprocessor, affects smoke components instrument below
Measurement accuracy.
2) steam extraction pump bypass flue gas and flue gas analyzer outlet flue gas, reality measure during externally arrange
Put.Do not carry out the gas cleanings such as desulfurization due to high-temperature flue gas, result in environmental pollution, and jeopardize measurement
Staff's is healthy.
3) flue gas preprocessor link is more, pipeline is relatively thin, causes flow resistance bigger than normal, and life-time service holds very much
Easily make flue gas flow rate slack-off, even blockage phenomenon, affect the real-time monitoring of main equipment smoke components.
If drawbacks described above can be overcome by technological innovation, the accurate of smoke components measurement will be greatly improved
Property, agility and the feature of environmental protection, make the work of measuring in China's industrial processes jump onto a new step.
Summary of the invention:
It is an object of the invention to, on the basis of tradition flue gas preprocessor, by technological transformation, improve cigarette
The accuracy of gas composition measurement, rapidity and the feature of environmental protection.This Novel flue gas preprocessor can be widely applied to electricity
Stand the smoke sampling processing links of the large industry equipment stove cigarette composition measurements such as boiler, Industrial Boiler and smelting furnace.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that and realizes:
A kind of flue gas preprocessor of the quick environmental protection of ne-leakage, including smoke sampling probe, air pump, threeway,
Filtration core, condenser, flue gas analyzer, gas bypass and smoke backflow pipe;Wherein,
The one end including smoke sampling probe is connected with industrial smoke pipeline, and the other end passes through air pump and threeway
Air inlet be connected, the first gas outlet of threeway passes sequentially through filtration core and condenser and flue gas analyzer
Air inlet is connected, and the gas outlet of flue gas analyzer is connected with smoke backflow pipe, one end of smoke backflow pipe
Being connected with the second gas outlet of threeway, the other end is connected with industrial smoke pipeline.
The present invention is further improved by, and also includes the venturi return channel being arranged on smoke backflow pipe,
The gas outlet of flue gas analyzer is connected with the throat of venturi return channel.
The present invention is further improved by, and the two ends of venturi return channel are all arranged on cigarette by adpting flange
On gas return duct.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is by by preposition for air pump anterior, when air pump runs, thereafter in filtration core and condenser
Flue, filtration core and condenser in flue gas be malleation, if sealing the tightest, do not result in yet
Flue gas preprocessor leaks into air, thus ensure that the accuracy that smoke components is measured.Return by setting up flue gas
Flow tube, makes bypass and the useless off-gas recovery being measured through flue gas analyzer flow in industrial equipment, rises
Arrive the effect of environmental conservation.
Further, by the venturi return channel arranged in gas bypass, make owing to venturi has injection
With, flue gas analysis exiting flue gas will be played certain swabbing action, thus improve whole fume treatment,
The speed of flow of flue gas in measurement system, makes the flue gas analyzer energy change that more preferably on-line tracing flue gas is divided into,
There is higher quick characteristic.
Therefore, the flue gas preprocessor that the present invention provides has ne-leakage, the quick and feature of environmental protection.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of prior art flue gas preprocessor;
Fig. 2 is the structural representation of flue gas preprocessor of the present invention;
In accompanying drawing, the list of parts representated by each label is as follows:
1, smoke sampling probe, 2, air pump, 3, threeway, 4, filtration core, 5, condenser, 6, cigarette
Edema caused by disorder of QI analyzer, 7, gas bypass, 8, venturi return channel, 9, smoke backflow pipe.
Detailed description of the invention:
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Bright, it is not intended to limit the scope of the present invention.
Embodiment 1
As in figure 2 it is shown, the flue gas preprocessor of the quick environmental protection of a kind of ne-leakage, including smoke sampling probe 1,
Air pump 2, threeway 3, filtration core 4, condenser 5, gas bypass 7, venturi return channel 8 and flue gas return
Flow tube 9.
Wherein, compare Fig. 1, and first air pump 2, threeway 3 and gas bypass 4 is preposition in filtration core 4 and
Condenser 5 is anterior, when air pump 2 runs, in flue, filtration core 4 and condenser 5 thereafter
Flue gas is malleation, if sealing the not tightest, flue gas will not result in flue gas toward external leakage in system
Preprocessor leaks into air, thus ensure that the accuracy that smoke components is measured.Meanwhile, smoke backflow is set up
Pipe 9, makes bypass and the useless off-gas recovery being measured through flue gas analyzer flow in industrial equipment, plays
The effect of environmental conservation.
Further, the venturi return channel 8 arranged in gas bypass, owing to venturi has ejector action,
Flue gas analysis exiting flue gas will be played certain swabbing action, thus improve whole fume treatment, measurement
The speed of flow of flue gas in system, makes the flue gas analyzer energy change that more preferably on-line tracing flue gas is divided into, has
Higher quick characteristic.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all the present invention's
