Abstract
The invention relates to a hand-held combustion gas detector, and belongs to the environment engineering technology field. The detector comprises a housing, a combustion gas detecting head, a central processor, a flowmeter and a cell. An air inlet and an air outlet are arranged in two ends of the housing. An air pump is arranged at the air inlet and the flowmeter and the combustion gas detecting head are arranged at the air outlet. The flowmeter and the output end of the combustion gas detecting head are connected with the central processor. The output end of the central processor is connected with a display screen. The cell supplies power for the air pump, the flowmeter, the combustion gas detecting head, the central processor and the display screen. The hand-held combustion gas detector employs the flowmeter to count inputted air quantity and employs the combustion gas detecting head to count combustion gas quantity, the combustion gas concentration can be obtained in real time, and the detector is simple and effective.
Description
Technical field
The present invention relates to a kind of hand-held coal gas detection instrument, belong to field of environment engineering technology.
Background technology
Existing coal gas detection instrument detects the ability mostly only having and find that gas concentration exceedes a certain threshold value and namely reports to the police, and can not reflect the concentration change of combustion gas in real time.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of portable, immediately can test the detector of gas concentration.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of hand-held coal gas detection instrument, comprising: housing, combustion gas detecting head, central processing unit, flowmeter and battery; The two ends of described housing are shaped with air intake opening and gas outlet respectively; Described air intake opening place is provided with air pump, described flowmeter and combustion gas detecting head and is arranged at described gas outlet place; Described flowmeter is connected described central processing unit with the output terminal of combustion gas detecting head; The output terminal of described central processing unit is connected to display screen; Described battery is described air pump, flowmeter, combustion gas detecting head, central processing unit and display screen are powered.
Such scheme further improves and is: described housing has the interface for described battery charges.
Such scheme further improves and is: described air intake opening is equipped with screen pack.
Hand-held coal gas detection instrument provided by the invention, utilizes flowmeter to add up and enters air capacity, with combustion gas detecting head statistics gas quantity, immediately can draw gas concentration, simply, effectively.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the present invention's preferred embodiment structural representation.
Number in the figure is schematically as follows: 1-housing, 2-air intake opening, 3-gas outlet, 4-air pump, 5-combustion gas detecting head, 6-screen pack, 7-flowmeter.
Embodiment
Embodiment
The hand-held coal gas detection instrument of the present embodiment, as shown in Figure 1, comprising: housing 1, combustion gas detecting head 5, central processing unit, flowmeter 7 and battery; The two ends of housing 1 are shaped with air intake opening 2 and gas outlet 3 respectively; Air intake opening 2 place is provided with air pump 4, flowmeter 7 and combustion gas detecting head 5 and is arranged at gas outlet 3 place; Flowmeter 7 is connected central processing unit with the output terminal of combustion gas detecting head 5; The output terminal of central processing unit is connected to display screen; Battery is that above consuming parts is powered.
After starting the detector of the present embodiment, flowmeter 7 and combustion gas detecting head 5 standby, air pump 4 starts, and according to housing 1 size, the air time replaced in housing is about 1 minute completely, so, flowmeter 7 and combustion gas detecting head 5 standby 1 point started after 30 seconds, after starting latter 1 minute, and the air mass flow that central processing unit is added up according to flowmeter 7 and the gas quantity that combustion gas detecting head 5 detects, calculate gas concentration, display on a display screen.
Screen pack 6 is also equipped with at air intake opening 2 place, prevents dust from blocking combustion gas detecting head 5, affects measurement result.
The present invention is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
