Abstract
The utility model discloses a novel gas detecting and analyzing alarm device comprising a shell, a pretreatment pipe body, a sensor, an air inlet pipe and an exhaust pipe, wherein the shell is internally provided with a transmitter on which an air pump is fixed; the pretreatment pipe body is internally provided with a T-shaped partition plate; the outer side of the T-shaped partition plate is provided with a filter layer, and the inner side end of the T-shaped partition plate is provided with a ventilation terminal; the ventilation terminal on the T-shaped partition plate is directly connected with the air inlet pipe connected with the air inlet end of the air pump; the exhaust end of the air pump is connected with the exhaust pipe; the tail end of the exhaust pipe is located at the induction end of the sensor; the lower end face of the pretreatment pipe body is provided with an air hole. Compared with the prior art, the novel gas detecting and analyzing alarm device has the advantages that false alarm and zero drift caused by the condition that water, dust and other impurities enter the sensor can be avoided due to the adoption of the structure; meanwhile, airflow which is instable in the past is stably transmitted into the front end of the sensor in a pumping way, and the gas detecting stability is also greatly improved.
Description
Technical field
The utility model relates to a kind of gas detection apparatus, relates 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 the false alarm that runs into moisture content, dust, strong wind weather in the continuous observation process of online gas inspection instrument.False alarm becomes very big obstacle reliable to toxic and harmful enforcement under unsettled weather condition, effective monitoring frequently.
Summary of the invention
The utility model, 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 utility model 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 utility model advantage is compared with prior art: the utility model 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 the 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.
