Abstract
The utility model discloses an easy-to-clean gas chamber applied to a continuous emission monitoring system (CEMS), which comprises a gas chamber measuring tube body, wherein both ends of the gas chamber measuring tube body are provided with optical lens assemblies, a gas inlet hole and a gas outlet hole are arranged on the tube wall of the gas chamber measuring tube body, and cover plates are covered on the gas inlet hole and the gas outlet hole. The cover plates arranged on the left gas inlet hole and the right gas outlet hole of the gas chamber are made into a movable connecting type and are fixed on the gas chamber through a plurality of screws, when the gas chamber needs to be checked or cleaned, the cover plates only needs to be dismounted, the surfaces of lens in the optical lens assemblies can be exposed, the direct cleaning is convenient, the key optical lens assemblies and optical fiber elements do not need to be dismounted, the unnecessary damage is avoided, and simultaneously, the maintenance and the cleaning become easy.
Description
Technical field
The utility model relates to field of analytic instrument, and especially the air chamber field is specially the air chamber easy to clean among a kind of CEMS of being applied to.
Background technology
In at present a lot " flue gas automatic monitored control system (CEMS) ", a kind of air chamber of widespread use is as a kind of means of Measurement and analysis, and the quality of its air chamber design will directly have influence on the accuracy of the measurement data of analytical instrument.Because mostly the CEMS system is direct collection for the collection of gas in the flue, pass through filter core and filtered most steam and dust, but inevitably gathering the still old part steam of gas and the dust of returning enters in the air chamber of analysis, time one will pollute two ends eyeglass and the inwall of analyzing in the air chamber for a long time, the many compositions of gas in the flue are the gas with corrosion property simultaneously, except meeting contamination gas chamber interior walls, also can cause measurement inaccurate, analysis data deviation etc. are adverse influence very.Now most air chamber design, Lens assembly is installed in the two ends of air chamber, the air chamber left and right sides is fixed with the joint of tracheae, if air chamber inside or eyeglass pollute, then need whole air chamber parts are taken out, pull down the Lens assembly at air chamber two ends, then the gentle chamber interior of eyeglass is cleaned and wiping.Not only time-consuming, and when comparatively accurate parts such as dismounting optical mirror slip and the optical fiber that is attached thereto, be easy to cause unnecessary damage.
The utility model content
The purpose of this utility model provides the air chamber easy to clean among a kind of CEMS of being applied to, and easily causes the problem of damage when cleaning with the air chamber dismounting Lens assembly that solves prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of air chamber easy to clean that is applied among the CEMS, comprise that two ends have the air chamber measurement cylindrical shell of nozzle, described air chamber is measured in the nozzle of cylindrical shell two ends and is separately installed with optical lens module, it is characterized in that: described air chamber is measured on the barrel of cylindrical shell near the two ends nozzle and is had into and out of pore, describedly all be covered with removable cover plate on pore, described cover plate plate face is measured the cylindrical shell barrel with the air chamber around pore and is closely contacted.
Described a kind of air chamber easy to clean that is applied among the CEMS, it is characterized in that: described air chamber is measured on the barrel of cylindrical shell near the two ends nozzle and is formed concave station respectively, describedly lay respectively in each self-corresponding concave station into and out of pore, described cover plate covers respectively on pore, and cover plate closely contacts with each self-corresponding concave station table top.
Described a kind of air chamber easy to clean that is applied among the CEMS is characterized in that: described cover plate is fixed on air chamber by a plurality of socket head cap screws and measures on the cylindrical shell barrel.
Described a kind of air chamber easy to clean that is applied among the CEMS is characterized in that: described cover plate and air chamber are measured between the cylindrical shell barrel and are respectively arranged with elastomeric pad.
Advantage of the present utility model is:
The utility model with air chamber about cover plate on the pore make movably connected, with a plurality of screw retention on air chamber, check or clean air chamber if desired, only cover plate need be pulled down, direct cleaning is convenient on the surface that can expose eyeglass in the optical lens module, does not then need dismounting for the optical lens module of key and optical fiber spare, avoided unnecessary damage, made also that simultaneously maintenance and cleaning become easy.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of air chamber easy to clean that is applied among the CEMS, comprise that two ends have the air chamber measurement cylindrical shell 1 of nozzle, air chamber is measured in the cylindrical shell 1 two ends nozzle and is separately installed with optical lens module 2,3, air chamber is measured on the barrel of cylindrical shell near the two ends nozzle and is formed concave station respectively, have air admission hole 4 in concave station with the air chamber internal communication, have venthole 5 in another concave station with the air chamber internal communication, cover plate 6,7 respectively by a plurality of socket head cap screws 8,9 can cover with pulling down, venthole 4, on 5, and cover plate 6,7 measure cylindrical shell 1 barrel with each self-corresponding air chamber as the concave station table top closely contacts, at cover plate 6,7 and air chamber measure between cylindrical shell 1 barrel and also be respectively arranged with elastomeric pad 10,11.
During work, light source becomes directional light through optical fiber behind the optical lens module of air chamber one end and incides in the air chamber.Part light is absorbed by the gas to be measured that the air admission hole from air chamber measurement cylindrical shell enters into air chamber, and remaining light is received in the optical fiber through the optical lens module of the other end of air chamber, finally by spectrometer analysis.
