Dust sensor in existing technology in the flue gas environment of high humility typically uses vertically arranged mode, this mode
In the flue gas emission measurement chamber device that the dust sensor of installation uses, after the flue gas of high humidity, high dirt mixes in measuring chamber,
High humidity, high dirt flue gas in the particulate matter that is relatively large in diameter be less prone to discharge, fouling can be formed in measuring chamber accumulated inside, caused
System detectio mistake, when often result in data distortion.
Utility model content
The purpose of this utility model is that the utility model purpose is realized a kind of wet according in place of above-mentioned the deficiencies in the prior art
Flue gas emission measurement device, including chamber body, chamber attemperator, measurement chamber, fiber optic receiver, described optical fiber receive
Head is set in described chamber body, forms a measurement chamber with chamber body, it is characterised in that in described chamber body
One section of chamber attemperator is set outside right side, and the described top measured on the left of chamber sets an intake interface；In measurement chamber
Lower section on the left of room sets an outlet interface；Described intake interface is in the structure expanded gradually downward；Outlet interface is in gradual
The structure reduced downwards.
The left side of fiber optic receiver described further sets an optical-fibre channel, described optical-fibre channel and fiber optic receiver
It is connected；One optical fiber receiver hole is set in described fiber optic receiver.
The left side of optical-fibre channel described further sets mounting flange；Described mounting flange and chamber body are screw thread
Attachment structure.
One supporting pipeline further is set in the left side of described mounting flange；One is set in described supporting pipeline to hang down
The compressed air piping directly run through, one horizontal pipe is set in the left side of described compressed air piping, put with dust sensor
Big device connection.
A control button, liquid crystal display further are set on described dust sensor amplifying device.
Insulation material inside chamber attemperator described further is asbestos.
Of the present utility model have technical effect that is solved after the flue gas of high humidity, high dirt mixes in measuring chamber, high humidity,
The particulate matter being relatively large in diameter in the flue gas of high dirt is less prone to discharge, and can form fouling in measuring chamber accumulated inside, cause system
Detect mistake, when the problem of often resulting in data distortion.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is top view of the present utility model.
Fig. 4 is left view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
With reference to shown in Fig. 1-Fig. 3, a kind of wet flue gas emission measurement device in embodiment of the present utility model, including chamber
Body 1, chamber attemperator 2, measurement chamber 3, fiber optic receiver 4, fiber optic receiver 4 is set in chamber body 1, with chamber sheet
Body 1 forms a measurement chamber 3, and one section of chamber attemperator 2 is set outside the right side of chamber body 1, the left side of measurement chamber 3
Top sets an intake interface 5；In the lower section in the left side of measurement chamber 3, one outlet interface 6 is set；Intake interface 5 is in gradually downward
The structure of expansion；Outlet interface 6 is in the structure reduced gradually downward.Such mechanism ensure that when the air inlet connecting of measurement chamber 3
Mouthfuls 5 up in the structure expanded gradually downward, and in funnel-form, outlet interface 6 is in the structure reduced gradually downward in lower section,
In funnel-form, when flue gas is from top to bottom quickly through measurement chamber 3, intake interface 5 and outlet interface 6 be designed to down funnel-form and
Funnel-form, it is easy to the flue gas of high humidity, high dirt uniformly to be mixed in measuring chamber, while the particulate matter being relatively large in diameter is easier to discharge, no
Fouling can be formed in measuring chamber accumulated inside, using gas channels but on the top of measurement chamber 3, solve measurement field inaccuracy
Caused measurement result problem devious, while artificial maintenance times can also be reduced, because horizontal measurement chamber 3 makes
Obtaining the moisture in flue gas or flue dust can cross and run through measurement chamber, will not be deposited again in chamber, even if there is deposition, also due to
The design of conical hopper shape structure and voluntarily slide discharge chamber.So as to cause system detectio mistake, when often result in data
The problem of distortion, occurs.
With reference to shown in Fig. 2, Fig. 3, the left side of fiber optic receiver 4 sets an optical-fibre channel 41, optical-fibre channel 41 and optical fiber
Head is received to be connected；Optical fiber receives 4 one optical fiber receiver holes 42 of upper setting, and the left side of optical-fibre channel 41 sets mounting flange 7；Peace
