Description
Technical field
The present invention relates to pulp technology for making paper, more particularly to a kind of air draft detection method.
Background technology
Currently, in paper-making process, web dryness generally improves using steam-heated mode in papermaking dry portion, to keep
The thermal efficiency of drying section, generally use gas hood all close entire drying section, meanwhile, to keep drying cylinder clean, drying section is normal
Some chemicals of keeping a public place clean often are added, so as to cause a large amount of residual water vapor, paper dirt and chemical molecular is generated in drying section, and are made
Paper drying section uses closed hood, whole system to be discharged by ventilating system air draft band due to long-time closed circulation, gas hood
While dividing, also a large amount of paper dirt.It when being filtered paper dirt, needs to study existing gas hood air draft, detect
The paper dust concentration of air draft, so as to effectively take filters.But existing paper dirt detection device precision is poor, and
Paper dust concentration situation can not be grasped in real time.
Invention content
The present invention in order to solve problems in the prior art, provides one kind and is detected convenient for paper dust content, accuracy of detection is higher
Air draft detection method.
Specific technical solution is as follows：A kind of air draft detection method, includes the following steps：A) sampling pipe is inserted into exhaust duct
Road, air draft is by sampling pipe into air inlet chamber；B) gas chamber is irradiated by light, reception device receives the scattering light of gas；C) it receives
Device converts optical signals to electric signal and is transferred to microcontroller；d）Microcontroller is sent out paper dust concentration in air draft by wireless network
Give display device.
It is the attached technical scheme of the present invention below：
Preferably, the gas chamber is arranged in dark surrounds, and light is sent out by laser generator, to avoid ambient light
Influence of the line to scattering light, prevents accuracy of detection impacted.
Preferably, the collection tube includes barn door and control panel, and barn door and control panel are arranged in collection tube
Air inlet, by be arranged in barn door, can prevent extraneous light from, into air inlet chamber, influencing measurement accuracy by collection tube, lead to
Setting control panel is crossed, the size of air inlet can be controlled, to control air inflow.
Preferably, the reception device is arranged towards the light sent out with laser emitter in 45 °, consequently facilitating
The reception of scattering light.
Preferably, operation panel and barn door are equipped in the gas chamber, it is logical for air-flow between operation panel and barn door
Road can control paper dirt diffusion velocity by the way that operation panel is arranged, to avoid the diffusion of paper dirt from polluting very much laser emitter soon.
The technique effect of the present invention：A kind of air draft detection method of the present invention can make staff grasp air draft in real time
Paper dust content, convenient for adjusting measure according to the variation of paper dust content；Furthermore it is possible to effectively promote the detection essence of paper dust content
Degree.
