Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without any creative labor, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model stationary source concentration analysis device.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
Fig. 1 is the structural schematic diagram of the utility model stationary source concentration analysis device.As shown in Figure 1, the concentration analysis
Device includes: multiple acquisition devices 1 and flow controller 2.The collection terminal of the multiple acquisition device 1 with stationary source to be analyzed
3 acquisition port 3-1 is connected, and the output end of the acquisition device 1 is connect with the flow controller 2.The flow controller 2
For controlling the gas flow of the acquisition device acquisition.For example, flow controller 2 can be set to 2L/min, can also set
It is set to 1.5L/min, specific flow number is set according to actual needs.
Each acquisition device 1 includes sampling pipe, time switch and solenoid valve, and time switch is connect with solenoid valve, solenoid valve
It is connect with sampling pipe.Each time switch is set with the on-off period of itself, such as -2 when 1 when is connected to, remaining period disconnects.Institute
State the on off operating mode that the on-off period that acquisition device is set by the time switch controls the solenoid valve, time switch connection
When, solenoid valve is connected；When time switch disconnects, solenoid valve is disconnected.And then the acquisition is controlled by the on off operating mode of solenoid valve
The acquisition state of pipe, when solenoid valve is connected, collection tube is worked normally, and carries out the acquisition of object to be measured；When solenoid valve disconnects, acquisition
Pipe stops working.Therefore, in each acquisition device 1, the connection period that collection tube is set according to time switch carries out stationary source
The data of different periods acquire.
The on-off period that time switch is set in different acquisition devices is different, and the connection period is not overlapped between each other.
It is to avoid influencing between each other, lead to final number to guarantee that each period only has a collection tube and be acquired work in this way
According to the error of acquisition.For example, carry out whole day acquisition in 24 hours using 12 sets of acquisition devices, then it can be in first set acquisition device
Time switch is set as connection when 0:00~2:00, then 0:00~2:00 is acquired the object to be measured of stationary source；Second set
Time switch is set as 2:00~4:00 connection in acquisition device, then 2:00~4:00 adopts the object to be measured of stationary source
Collection；Time switch is set as 4:00~6:00 connection in third set acquisition device, then 4:00~6:00 is to the to be measured right of stationary source
As being acquired；It successively postpones, then time switch is set as 22:00~24:00 connection in the 12nd set of acquisition device, then 22:00
~24:00 is acquired the object to be measured of stationary source.Therefore, it is not overlapped when the connection period of different timing switch setting, and
When the summation of the connection period of all time switches is 24 hours, it can satisfy above-mentioned requirements.
According to the actual demand of monitoring, the summation of the connection period of all time switches can be set as other periods, adopt
The number of acquisition means is also to set according to actual needs, and the Lifetime of time switch according to the summation for being connected to the period and is adopted
The number of acquisition means further determines that, however, it is desirable to guarantee that the connection period of different timing switch setting is not overlapped.
Different according to object to be analyzed in the acquisition device of the utility model, the type of sampling pipe is different, when to be analyzed right
When as gas, using gas sampler；When object to be analyzed is particulate matter, using particle sampling pipe.
