Abstract
The utility model discloses a kind of pernicious gas to examine and determine exhaust apparatus, belong to field of gas detection, including gas testing device, also include gas circuit one, gas circuit two, reversal valve and blast pipe, gas circuit one and gas circuit two are connected on the transducer room in gas testing device, and transducer room is connected by pipeline with reversal valve, and reversal valve is connected with blast pipe, the end of blast pipe sets guard abat-vent, and adsorbent is set on blast pipe.Pernicious gas calibrating exhaust apparatus of the present utility model prevents rainwater to pour in down a chimney and prevents outdoor flying bird to be strayed into pipeline in pipe outlet installation guard abat-vent, by filling toxic gas adsorbent in purification tank, toxic and harmful gas is adsorbed, the harmfulness for discharging outdoor gas is minimized, can alert detection operating personnel in time in the detection alarm that exhaust pipe mouth is set prevents from polluting environment.
Description
Technical field
Field of gas detection is the utility model is related to, specifically, the utility model is related to a kind of pernicious gas calibrating row
Device of air.
Background technology
The composition of each pernicious gas in detection mine is needed in coal production, the composition of wherein CO gas is desirable
Emphasis measure, the integrated gas calibration equipment that measure CO gas needs to use, the present apparatus produces when discharging and examining and determine
Residual air when be the problems such as following be present to outdoor discharge, this discharge duct by a diameter of 150mm aluminum foil pipes：1st, aluminum foil pipe
Road is retractility pipeline, because laboratory integration gas calibration device away from window farther out, need to by the use of two sections of aluminum foil pipes as discharge duct,
Such as take no action to hold discharge duct, then pipeline can be caused sagging, and influence exhaust effect；2nd, because stretching out aluminum foil pipe outside window
It is the mouth of pipe for opening, it is impossible to avoid outdoor flying bird from entering discharge duct by the mouth of pipe, so as to cause necessarily to influence on calibrating installation；
3rd, when examining and determine toxic and harmful gas detection alarm（Such as mining carbon monoxide transducer）, certain residual air can be produced.Because of aluminium
Paper tinsel pipe discharge duct does not have a purifier, and caused residual air is exhausted directly in air in verification process, has one to atmospheric environment
Fixed pollution.
The content of the invention
Technical problem to be solved in the utility model proposes solution aiming above mentioned problem.
In order to solve the above-mentioned technical problem, technical scheme is used by the utility model：A kind of pernicious gas calibrating row
Device of air, including gas testing device, in addition to gas circuit one, gas circuit two, reversal valve and blast pipe, the gas circuit one and gas circuit two
It is connected on the transducer room in gas testing device, transducer room is connected by pipeline with reversal valve, reversal valve and blast pipe
Connection, the end of the blast pipe set guard abat-vent, adsorbent are set on blast pipe.
Preferably, the blast pipe inner wall at end is provided with detection alarm.
Using the technical solution of the utility model, following beneficial effect can be obtained：
Pernicious gas calibrating exhaust apparatus of the present utility model prevents rainwater in pipe outlet installation guard abat-vent
Pour in down a chimney and prevent outdoor flying bird to be strayed into pipeline, by filling toxic gas adsorbent in purification tank, by toxic and harmful gas
Absorption, the harmfulness for discharging outdoor gas is minimized, and inspection can be alerted in time in the detection alarm that exhaust pipe mouth is set
Surveying operating personnel prevents from polluting environment.
Brief description of the drawings
Brief description is made to the content expressed by each accompanying drawing of this specification and the mark in figure below：
Fig. 1 is structural representation of the present utility model；
Mark in above-mentioned figure is：1st, gas testing device；2nd, gas circuit one；3rd, gas circuit two；4th, transducer room；5th, commutate
Valve；6th, blast pipe；7th, adsorbent；8th, alarm is detected；9th, guard abat-vent.
Embodiment
Below against accompanying drawing, by the description to embodiment, to specific embodiment of the present utility model as involved
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of each component, construction, each several part etc. make into
The detailed description of one step.
As shown in figure 1, this pernicious gas calibrating exhaust apparatus includes gas testing device 1, in addition to gas circuit 1, gas circuit
23, reversal valve 5 and blast pipe 6, gas circuit 1 and gas circuit 23 are connected on the transducer room 4 in gas testing device 1, sensing
Device room 4 is connected by pipeline with reversal valve 5, and reversal valve 5 is connected with blast pipe 6, and the end of blast pipe 6 sets guard abat-vent 9,
Adsorbent 7 is set on blast pipe 6, and the inner wall at end of blast pipe 6 is provided with detection alarm 8.
In use, the gas that detects will be needed to be passed through gas circuit and then detected in gas testing device 1, gas circuit 1 can be with
It is passed through and does not have corrosive gas to be checked, gas circuit 23 can be passed through with corrosive gas to be checked, such separate detection,
The life-span of gas circuit, which can be extended, can also improve Detection accuracy.Twisting reversal valve 5 after the good gas to be checked of detection can exclude
Gas, the gas of exclusion are then exhausted to outdoor after blast pipe 6 is interior by the harmful components in the adsorbed gas of adsorbent 7；
The end of blast pipe 6 sets the detection alarm 8 of inwall setting to detect the remaining pernicious gas composition in exclusion gas simultaneously
Timely warning reminding operating personnel's timely processing, the guard abat-vent 9 that the end of blast pipe 6 is set can prevent rainwater pour in down a chimney and
Outdoor flying bird is prevented to be strayed into pipeline.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that methodology and technical scheme of the present utility model are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in the utility model
Protection domain within.
