Description
Technical field
The utility model relates to gas analyzer in a kind of characterization processes pipeline, belongs to the checkout equipment technical field.
Background technology
In order to guarantee safety in production, need the carbon monoxide and the oxygen content of gas in the process pipe of test section in the metallurgy industry iron-making coal-injecting operation, the gas analyzer that coal powder injection is used is generally PS6600 type gas analyzer.This gas analyzer is mainly become by probe, blowback cabinet and analysis group, gas filters after enter the analysis cabinet behind the sample tracheae through filter probe device one-level in the process pipe, behind sampling solenoid valve, steam-water separator, condenser, supply with power afterwards by aspiration pump, with it behind three-way solenoid valve, five-way manual switching valve, filter after the sampling flow meter enters analytical instrument analysis through membrane filter, the tail gas after the analysis enters through evacuated tube and analyzes outside the cabinet in the atmosphere.The effect of blowback cabinet is that probe and sample tracheae are purged, and the dust or the impurity that adhere in it are cleared up.Blow in to probe and the purging of filtrator thereof being, to probe with analyze sample tracheae purging between cabinet for blowing outward.System brings into operation from blowback when analyser starts, its circulation pattern is: blow in popping one's head in earlier---carry out the sample tracheae again and blow outward, blow in no matter being or the outer sampling solenoid valve that blows all is in closed condition, purging finishes and begins sampling, aspiration pump begins to rotate extraction sample gas, three-way solenoid valve gets 15 seconds gas to retain in the emptying sample tracheae of electric first emptying, the sampling solenoid valve is opened and is begun to extract the analysis of sample air to open beginning when sampling then, reach blow, pop one's head in popping one's head in again behind the setting-up time outer blowing, so circulation analysis time.In the actual detected process, impurity is more in the gas in the process pipe that has, and makes that filter probe device impurity screening is incomplete, makes sample tracheae etc. locate impurity and retains.The effect of blowback cabinet is exactly with the control of nitrogen and solenoid valve that the impurity purging is clean.But when blowing outside probe, the sampling solenoid valve is in closed condition in the cabinet owing to analyze, thus though there is nitrogen to blow to the sample tracheae, there is not discharge pipe from probe, so can not form the purging path.Sample tracheae or the sampling solenoid valve place impurity of just can causing of long duration like this stops up, and analyser is shut down, and safety in production is impacted, and also makes troubles for the surfaceman.
The utility model content
The utility model purpose provides gas analyzer in a kind of characterization processes pipeline, and the outer impurity that blows in the up-to-date style tracheae of probe will be gone out to analyze outside the cabinet by blowback, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: gas analyzer in the characterization processes pipeline, comprise probe, blowback cabinet and analysis cabinet, the end of popping one's head in connects process pipe, the other end is communicated with the blowback cabinet respectively and analyzes cabinet, described analysis cabinet comprises the sampling solenoid valve, steam-water separator, condenser, aspiration pump, the five-way manual switching valve, the sampling flow meter, the sampling solenoid valve is a three-way solenoid valve, be provided with three interfaces, first interface is communicated with probe by the sample tracheae, second interface is connected with sampling solenoid valve outlet side, sampling solenoid valve outlet side is communicated with steam-water separator, and the 3rd interface is communicated with atmosphere.Sampling solenoid valve outlet side is communicated with aspiration pump by steam-water separator, condenser, and the aspiration pump other end is communicated with the sampling flow meter by the five-way manual switching valve, and the sampling flow meter other end is communicated with analyser.
Probe is outer to be blown impurity in the up-to-date style tracheae and will be blown out from the 3rd interface of sampling solenoid valve by blowback nitrogen and analyze outside the cabinet, and the gas during sampling in the process pipe passes through from the path of first interface of sampling solenoid valve and second interface.So neither influence sampling analysis, solved sample tracheae and the easy blockage problem of sampling solenoid valve again.
The beneficial effects of the utility model are: neither influence sampling analysis, solved sample tracheae and the easy blockage problem of sampling solenoid valve again.Have characteristics simple in structure, easy to use, safe, reduced working strength of workers, also reduced the maintenance and repair parts expense.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram;
Among the figure: 1. probe, 2. the reflection cabinet, 3. the sampling solenoid valve, 4. steam-water separator, 5. condenser, 6. aspiration pump, 7. the five-way manual switching valve, 8. the sampling flow meter, 9. analyze cabinet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
With reference to accompanying drawing 1, gas analyzer in the characterization processes pipeline, comprise probe 1, blowback cabinet 2 and analysis cabinet 9, the end of popping one's head in connects process pipe, the other end is communicated with the blowback cabinet respectively and analyzes cabinet, described analysis cabinet comprises sampling solenoid valve 3, steam-water separator 4, condenser 5, aspiration pump 6, five-way manual switching valve 7, sampling flow meter 8, the sampling solenoid valve is a three-way electrovalve, be provided with three interfaces, first interface is communicated with probe by the sample tracheae, second interface is connected with sampling solenoid valve outlet side, sampling solenoid valve outlet side is communicated with steam-water separator, and the 3rd interface is communicated with atmosphere by the Buddhist rubber tube.Steam-water separator is communicated with aspiration pump by condenser, the aspiration pump other end is communicated with the sampling flow meter by the five-way manual switching valve, can sample and calibrate selection by the five-way hand valve, sampling flow meter end in addition is communicated with analyser, the other bypass flow meter that is provided with of aspiration pump, its effect is to avoid the sample tracheae to stop up and aspiration pump vacuumizes, and the effect of condenser can be discharged through aqua storage tank the water that condensation in the sample gas goes out by peristaltic pump.
System brings into operation from blowback when analyser starts, its circulation pattern is: blow in popping one's head in earlier---carry out the sample tracheae again and blow outward, no matter blow the still outer sampling solenoid valve that blows in the time and all be in closed condition, purging finishes and begins sampling, aspiration pump begins to rotate extraction sample gas, three-way solenoid valve gets 15 seconds gas to retain in the emptying sample tracheae of electric first emptying, the sampling solenoid valve is opened and is begun to extract the analysis of sample air to open beginning when sampling then, reach blow, pop one's head in popping one's head in again behind the setting-up time outer blowing, so circulation analysis time.The sampling solenoid valve is must not be electric under original state, and first interface 1 is connected with the 3rd interface, gets electric back first interface 1 and the 3rd interface gateway and closes, and first interface is communicated with second interface gateway.Probe is outer to be blown impurity in the up-to-date style tracheae and will be blown out from the 3rd interface of sampling solenoid valve by blowback nitrogen and analyze outside the cabinet, and the gas during sampling in the process pipe passes through from the path of first interface of sampling solenoid valve and second interface.So neither influence sampling analysis and solved sample tracheae and the easy blockage problem of sampling solenoid valve again,, reduced surfaceman's labour intensity again, also reduced the maintenance and repair parts expense simultaneously both for safety in production provides assurance.
