Abstract
The utility model discloses a turbulence-free multicomponent gas monitor. The monitor comprises a gas detection room and a gas detection sensor, wherein the cross section of the gas detection room is circular; a concave platform is arranged in the center of the gas detection room; the gas detection sensor is fit in the concave platform and is concentric with the concave platform; a groove is formed in the center of the concave platform; a conical bulge is arranged in the center of the groove; a plurality of seal rings are also arranged between the gas detection room and the gas detection sensor; three vent lines communicated with the concave platform are uniformly distributed on the cross section of the gas detection room. The monitor has the beneficial effects that the conical bulge plays a role of drainage, prolongs the detection response time and improves the stability of detection precision; meanwhile, inlets and outlets are formed in three directions, thus providing multiple channels and being convenient for various gas detection sensors to carry out multicomponent detection on measured gases; the surface of an inner cavity of the gas detection room is plated with corrosion-resistant polytetrafluoroethylene materials, thus improving the corrosion resistance of the gas detection room and effectively reducing the equipment fault rate.
Description
Technical field
The utility model relates to multicomponent gas on-line monitoring in environment supervision instrument, relates in particular to without turbulence type multicomponent gas monitor.
Background technology
Along with economic fast development, China sharply increases because of coal fire discharged sulphuric dioxide (SO2) and oxides of nitrogen (NOx), the dusty gas discharge that some waste incinerations form simultaneously, discharge of chemical industry dusty gas etc., cause serious environmental pollution, therefore country has formulated corresponding laws and regulations, to enterprise's solar obligation on-line monitoring system of flue gas discharge of some fume emissions.Along with environmental pollution more and more receives the concern of government department and general public, environmental protection relevant portion is also more and more stricter to the monitoring dynamics of pollution source gas discharging, the component of gas-monitoring is also more and more, some fields also need to monitor C0, CO2, HCL, HF, H2S etc. simultaneously, in the time detecting multi-component pollution source gas, just need gas sensing chamber installing gas detecting sensor to detect, gas detection sensor is arranged on gas sensing chamber top, utilizes the diffusion that gas-monitoring flows through that detected gas is detected with the contact of sensor detection sensitive surface.Find in actual use to rely on the diffusion that detects gas that gas is contacted with gas sensor, it is long that gas detection sensor detects the response time, because gas sensing chamber inside is designed without drainage, air-flow is in the inner turbulent flow that easily forms of gas sensing chamber, detect very unstable, some corrosivity monitor gases, easily by the inner chamber corrosion of gas sensing chamber, cause surveying instrument to damage simultaneously.
Utility model content
To be that the design of existing gas monitoring instrument is unreasonable cause detecting unstable the technical problems to be solved in the utility model, and can not detect multicomponent gas, easily by gas attack inner chamber, provides a kind of without turbulence type multicomponent gas monitor for this reason.
The technical solution of the utility model is: without turbulence type multicomponent gas monitor, it comprises gas sensing chamber and the gas detection sensor that xsect is rounded, central authorities of described gas sensing chamber are provided with concave station, described gas detection sensor fits in described concave station and with concave station and keeps concentric, described concave station central authorities are provided with groove, described groove central authorities are provided with conical protrusions, between described gas sensing chamber and gas detection sensor, be also provided with some O-ring seals, on the xsect of described gas sensing chamber, be evenly distributed with three vent lines that are communicated with concave station.
The sensing chamber of gas described in such scheme inside surface is coated with Teflon.
The improvement of such scheme is that described concave station inward flange is provided with external thread, and the adaptive place of described gas detection sensor and concave station is provided with external thread and realizes the threaded engagement of concave station and gas detection sensor.
The beneficial effects of the utility model are that conical protrusions plays drainage, make the gas that enters gas sensing chamber inside steadily rapidly with gas detection sensor contact, have improved the detection response time, and the stability of accuracy of detection; Be provided with 3 directions simultaneously and import and export, hyperchannel is provided, be convenient to multiple types gas detection sensor the polycomponent of measurement gas is detected; Gas sensing chamber surface of internal cavity plates corrosion-resistant Teflon material, has improved gas sensing chamber decay resistance, effectively reduces equipment failure rate.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, the utility model comprises gas sensing chamber 3 and the gas detection sensor 1 that xsect is rounded, central authorities of described gas sensing chamber are provided with concave station 5, described gas detection sensor fits in described concave station and with concave station and keeps concentric, described concave station central authorities are provided with groove 6, described groove central authorities are provided with conical protrusions 7, between described gas sensing chamber and gas detection sensor, be also provided with some O-ring seals 2, on the xsect of described gas sensing chamber, be evenly distributed with three vent lines 4 that are communicated with concave station.
Conical protrusions 7 plays drainage, makes the gas that enters the inner concave station of gas sensing chamber steadily rapidly with gas detection sensor contact, has avoided the generation of turbulent flow, has improved the detection response time, and the stability of accuracy of detection.
Three vent lines 4 of gas sensing chamber can be arranged to as required into and out of vent line, such as one be air inlet pipeline, all the other two is outlet pipe.Three vent lines provide hyperchannel, be convenient to multiple types gas detection sensor the polycomponent of measurement gas is detected.
Cause for fear of etchant gas absorption the loss of measuring component, and the corrosion of etchant gas to gas sensing chamber, can be coated with Teflon at gas sensing chamber inside surface.
In order to make the tightr of gas sensing chamber and gas detection sensor combination, can be provided with external thread at concave station inward flange, the adaptive place of described gas detection sensor and concave station is provided with external thread and realizes the threaded engagement of concave station and gas detection sensor, ensure like this tightness of gas sensing chamber and gas detection sensor, also guaranteed that the degree of accuracy of detection is stopped external environmental interference.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
