Description
Technical field
The utility model belongs to atmosphere pollution source detection apparatus more particularly to a kind of based on FTIR spectrum technology
Gas analyzer.
Background technology
Gas analyzer is a kind of equipment, such as FTIR, laser analyzer etc. in monitoring gaseous contamination source.It detects former
Reason is to be irradiated to pollution source gas by detection light so that detection light generation spectrum change, is polluted by analyzing spectrum change
The content of pollutant component in source gas.In actual monitoring process, in most pollution source gas content a large amount of dust with
And moisture is needed to ensure that under test gas is in high temperature drying state, be prevented during under test gas is drawn into gas compartment
Vaporous water under test gas liquefies and causes transfer pipeline to block after mix dust；Gas compartment carry out analysis detection when,
It needs the indoor under test gas of gas to be in high temperature drying state, prevents the vaporous water under test gas from liquefying and influence detection is precipitated
As a result.
Existing gas analyzer, generally use two heating components respectively add transfer pipeline and gas compartment
Heat, structure are not enough simplified, and manufacturing cost is high, and the space of instrument is also larger.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that a kind of simple in structure, design
Rational gas analyzer.
The purpose of this utility model can be realized by following technical proposal：
A kind of gas analyzer based on FTIR spectrum technology, including the gas compartment that is fixed on substrate, are used for
The heat tracing pipe of under test gas is conveyed, and for analyzing the data analysis module for obtaining testing result, the heat tracing pipe and gas
Under test gas pretreatment portion is provided between room, the pretreatment portion includes a heater box, and connection is provided in the heater box
The admission line and discharge duct of heat tracing pipe and gas compartment are provided with filtering sintering bar, the exhaust pipe on the admission line
Zirconia sensor is provided on road.
Preferably, the heater box is close to be fixed on a side wall of gas compartment and heater box shares one with gas compartment
A side wall, the admission line and discharge duct are connected to gas compartment across the side wall.
Preferably, being provided with several spaced branch pipes on the admission line, the branch pipe stretches out the heating
Case.
Compared with prior art, the utility model has following technological merit：
The utility model heats conveyance conduit and gas compartment by a heater box, simplifies gas analyzer
Internal structure, reasonable design.Filtering sintering bar and zirconia sensor are provided in heater box simultaneously,
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the sectional view of one embodiment of the utility model.
Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As depicted in figs. 1 and 2, the utility model provides a kind of gas analysis based on FTIR spectrum technology
Instrument, including the gas compartment 9 that is fixed on substrate, the heat tracing pipe 2 for conveying under test gas, and obtain inspection for analyzing
Survey the data analysis module 1 of result.A pretreatment portion is provided between gas compartment 9 and heat tracing pipe 2, pretreatment portion includes a heating
Case 3, heater box 3 are close to be fixed on a side wall of gas compartment 9, and heater box 3 shares a side wall with gas compartment 9, sets in this way
It sets, conveniently heater box 3 and gas compartment 9 can be heated simultaneously by a heating plate, to simplify gas analyzer
Internal structure.
It is provided with admission line 7 and discharge duct 8 in heater box 3, filtering sintering bar 4, exhaust are provided on admission line 7
Zirconia sensor 6 is provided on pipeline 8.As shown in Figure 1, one end of heat tracing pipe 2 is extend into heater box 3,7 He of admission line
One end of discharge duct 8 is connected with heat tracing pipe 2, and the other end of admission line 7 and discharge duct 8 is stretched by the side wall of gas compartment 9
Into gas compartment 9.It may be at heating shape always in this way, under test gas enters from heat tracing pipe 2 in this section of distance of heater box 3
State, to ensure that under test gas enters gas compartment 9 during being drained into monitoring point again from gas compartment 9 from monitoring point
In high temperature drying state.
In the present invention, heater box 3 is a closed box, and closed babinet can effectively reduce in heater box 3
The heat losses in portion, to reduce heating energy consumption.Several branch pipes 5 are provided on admission line 7, branch pipe 5 is pierced by 3 wall of heater box and draws
Go out, these branch pipes 5 are used to detect the flow velocity in place's admission line 7 by pressure difference.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
