Abstract
The invention discloses a novel gas detecting analysis alarm. The gas detecting analysis alarm comprises a housing, a preprocessed pipe body, a sensor, a gas intake pipe and an exhaust pipe, wherein a transmitter is mounted in the housing; a gas pump is fixed on the transmitter; a T-shaped partition plate is arranged in the preprocessed pipe body; a filter layer is arranged on the outer layer of the T-shaped partition plate; a ventilation terminal is arranged on the inner side end of the T-shaped partition plate; the ventilation terminal on the T-shaped partition plate is directly connected with the gas intake pipe; the gas intake pipe is connected with the gas intake end of the gas pump; the gas discharge end of the gas pump is connected with the exhaust pipe; the tail end of the exhaust pipe is located at the sensing end of the sensor; pores are formed in the lower end face of the preprocessed pipe body. Compared to the prior art, the structure of the novel gas detecting analysis alarm can prevent false alarm and zero drift due to impurities such as moisture and dust which enter the sensor; in the meantime, the pumping method is used to stably introduce the unstable gas flow into the front end of the sensor, so that the gas detection stability can be greatly improved.
Description
Technical field
The present invention relates to a kind of gas detection apparatus, relate in particular to a kind of new gas detection analysis alarm.
Background technology
At present, for reinforcement and the raising of occupational illness monitoring, make to seem particularly important for reliable, the effective monitoring of toxic and harmful.Make a general survey of domestic online gas inspection instrument industry, maximum problem is exactly in the continuous observation process of online gas inspection instrument, to run into the false alarm of moisture content, dust, strong wind weather.False alarm becomes very big obstacle reliable to toxic and harmful enforcement under unsettled weather condition, effective monitoring frequently.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, provides a kind of new gas detection analysis alarm.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of new gas detection analysis alarm, comprise housing, pre-service body, sensor, draft tube and gas outlet, in described housing, transmitter is installed, on described transmitter, be fixed with air pump, in described pre-service body, be provided with T shape dividing plate, T shape dividing plate outside is provided with filtering layer, T shape dividing plate medial extremity is provided with ventilative terminal, ventilative terminal on T shape dividing plate directly connects draft tube, draft tube is connected with air pump inlet end, air pump exhaust end connects gas outlet again, gas outlet end is positioned at sensor sensing end, described pre-service body lower surface is provided with pore.
The present invention's advantage is compared with prior art: the present invention has increased gas preprocessing part at the front end of common sensor, the mode of inhaling by pump is stably sent the gas after drainage filter dirt into gas sensor induction end, prevent from entering because of impurity such as moisture, dust false alarm and the zero point drift that sensor causes, the mode of meanwhile, inhaling by pump has also significantly improved the sensor front end of importing into of the unsettled steady air current of script the stability that gas detects.
