Description
Technical field
This utility model relates to a kind of gas concentration detection apparatus, is especially adapted for use in the gas concentration detection apparatus of complex environment (including high humidity environment), belongs to gas detection technology field.
Background technology
At present most domestic gas detection equipment, when processing without complicated prime, all normally cannot work under the severe site environment such as high humidity of complexity, dust, gas such as mix at the environment.Because under similar this complex environment, gas sensor easily lost efficacy, thus caused equipment fault.Portion gas detection equipment has carried out the pretreatment of complexity to environmental gas, while seriously adding equipment cost, also results in testing result substantial deviation.Therefore, design a kind of with low cost, can to while in complex environment, associated gas detects with gas sensor defencive function integrated gas detect equipment, be to be presently required to solve the technical problem that.
Utility model content
The purpose of this utility model is: the problem existed for above-mentioned prior art, proposes a kind of low cost, measures accurate, stable performance and the gas concentration detection apparatus strong to environmental suitability complicated and changeable.
In order to reach object above, a kind of gas concentration detection apparatus of the present utility model, with the first vacuum air suction pump of sensing chamber pipeline communication and the gas control valve that is arranged on described sensing chamber porch；It is characterized in that: also including gas purifier and the gas sensor being arranged in sensing chamber, the gas outlet of described sensing chamber connects with the entrance of gas purifier, and the air inlet with sensing chamber of working off one's feeling vent one's spleen of gas purifier connects.
The technical scheme that this utility model limits further as: at the air inlet of described gas control valve, be also equipped with gas filtration net.
Further, between the air inlet of the gas outlet of described gas purifier and described sensing chamber, the second vacuum air suction pump on pipeline, it is also equipped with.
Further, described gas detector includes gas concentration sensor and/or temperature sensor and or humidity sensor and/or PM sensor.
Further, also include and the rear class signal processing system of gas sensor communication connection.
The beneficial effects of the utility model: this utility model can carry out sample detecting to the associated gas in complex environment; the complex environment injury to sensor can be reduced again; automatically control; output detects data accurately; stable performance, reduce equipment cost; it is effectively protected sensor, improves the service life of equipment.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is the structural representation of one embodiment of this utility model.
Detailed description of the invention
Embodiment one
A kind of gas concentration detection apparatus of the present embodiment, basic structure is as it is shown in figure 1, include sensing chamber and the first vacuum air suction pump of sensing chamber's pipeline communication and be arranged on the gas control valve of sensing chamber porch；Also including gas purifier and the temperature sensor being arranged in sensing chamber, the gas outlet of sensing chamber connects with the entrance of gas purifier, and the air inlet with sensing chamber of working off one's feeling vent one's spleen of gas purifier connects.
Gas filtration net it is also equipped with to filter solid floating impurity at the air inlet of gas control valve.It is also equipped with the second vacuum air suction pump between the gas outlet and the air inlet of sensing chamber of gas purifier.Sensing chamber's internal gas circulation is purified, to protect detecting instrument after opening by the second vacuum air suction pump and gas purifier.
This utility model also includes and the rear class signal processing system of gas detector communication connection.
Regulation and control method of the present utility model includes: 1) direct Detection Method, controls the first outside gas to be detected of vacuum air suction pump extraction, and gas to be detected arrives sensing chamber after the control valve that drainage screen filters solid floating impurity, control airflow direction.Temperature sensor gas to be checked to sensing chamber is directly sampled, and automatically processed by rear class sampled data is analyzed process.2) after detection, closing control valve and the first vacuum air suction pump, open the second vacuum air suction pump and carry out gas purifier internal gas circulation purification, be rinsed sensing chamber purifying, protect detecting instrument.In closed circuit purification circuit, it is also possible to do not use the second vacuum air suction pump, carry out automatic purification by diffusion by the pipeline of communication with detection room Yu depurator.
This utility model carries out Automatic dispatching control, uses direct Detection Method sampled data to be acquired analyzing and processing, uses the closed circuit method of purification to protect sensor gas collecting sampling process.It can either accurately detect the associated gas temperature in environment, can reduce again the environment harmful effect to gas sensor, thus ensure that the long-term normal table of sensor works.
In addition to the implementation, this utility model can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of this utility model requirement.
