Survey, avoid poisonous and hazardous gas from being discharged into the external world, pollute environment.
Existing flue gas automatic monitoring system generally includes smoke collecting device, pretreatment system, gas analyzing apparatus, control
Device etc..Wherein the flue gas in flue need to be transferred in analytical instrument by flue gas into gas analyzing apparatus by sampling pump.It is full
For sufficient analytical instrument to the needs of rate of air sucked in required, sampling pump will ensure that flow and pressure are enough, air tight etc..Due to flue gas in sampling pump
Into inbound traffics are big, speed is fast, the particulate matter that is not filtered out in flue gas, dust etc. are easy to accumulate on sampling pump.Although can be with
Using back-blowing device, air blowback is compressed to sampling pump, but always there is dust and dirt to stay on sampling pump.Once dust and dirt on sampling pump
Excessively, sampling pump is blocked, then the load of sampling pump will increase, and cause to produce larger heat on sampling pump, or even burn
Sampling pump, causes the overtemperature protection measure of whole system.Accordingly, it is determined that the accumulation situation of dust and dirt, in time stopping system on sampling pump
System, cleaning sampling pump are extremely important.
A kind of flue gas analysis system of patent (day for announcing 2016.12.21, notification number CN205826629U) discloses a kind of cigarette
Qi leel analysis system, is connected by heat tracing pipeline with disposal of pollutants source, it includes control device and detachable with control device respectively
The sampling apparatus and analytical equipment of formula connection, sampling apparatus include high-temperature process unit and room temperature processing unit, and room temperature processing is single
Member includes cooling de-watering subelement and sampling pump, and high-temperature process unit is connected by analytical equipment with cooling de-watering subelement.Should
Patent is pumped by cooling de-watering subelement and routine sampling, avoids high cost high temperature sampling pump or the jet pump for needing injection gas
Use, improve the stability and controllability of sampling, reduce cost.But the patent can not be by flue gas to sampling pump
Dust and dirt is blocked and handled.As the accumulation of dust and dirt on sampling pump is until blocking, is easy to cause sampling pump and burns, and causes system
Chain reaction and economic loss.
Therefore it is simple in structure to be badly in need of one kind, it is easy for installation, dust and dirt on sampling pump can be monitored in real time and gather situation, and in necessity
Alarm reminds the flue gas automatic monitored control system of sampling pump cleaning.
Utility model content
In order to solve the above-mentioned technical problem, the utility model, which provides a kind of flue gas with flow alarm function control and monitors automatically, is
System, the system can monitor the flow of flue gas in sampling pump delivery outlet flue in real time, when the too small i.e. sampling pump of flue gas flow is by particle
After thing and dirt accumulation block a period of time, start alarm system and close sampling pump, damaged to prevent sampling pump because of blocking, really
Protect the lasting health operating of whole system.
The utility model provides following technical solution：
A kind of flue gas automatic monitored control system with flow alarm function control, including sampling pump, suspended body flowmeter and controller, are floated
Subflow gauge is connected with the output terminal of sampling pump, and suspended body flowmeter is connected controller with sampling pump, and controller can control sampling
The opening and closing of pump and suspended body flowmeter.
Preferably, the flue gas automatic monitored control system with flow alarm function control further includes capacitive approach switch, and condenser type connects
Nearly switch is arranged at 0.2~0.5L of suspended body flowmeter, and capacitive approach switch is connected with the input terminal of controller.
Preferably, suspended body flowmeter includes floating ball, and capacitive approach switch is triggered when floating ball is close produces open signal,
Open signal is output to controller.
Preferably, the flue gas automatic monitored control system with flow alarm function control further includes alarm system, alarm system and control
Device output terminal is connected.
Preferably, timer is provided with controller, timer carries out timing to opening signal duration, believes when opening
Number duration, controller closed sampling pump more than ten minutes, and controller starts alarm system.
Preferably, controller is PLC controller.
The beneficial effects of the utility model are：
1st, the utility model is simple in structure, easy for installation, of low cost.
2nd, capacitive approach switch is arranged at 0.2~0.5L of suspended body flowmeter by the utility model, and suspended body flowmeter
Floating ball if located in 0.2~0.5L nearby just explanation flue in flue gas flow it is too small, if this case continues very long
Between such as ten minutes, then mean extract flue gas sampling pump be blocked.It can be judged in time using capacitive approach switch
Whether sampling pump is blocked, and removes hand inspection from.
If the 3, the utility model sampling pump is blocked by particulate matter and dust, load excessive can be caused, sample pump temperature liter
It is high even to burn, cause system chain reaction and economic loss.Judge that sampling pump is blocked situation by capacitive approach switch,
And the situation is sent to controller, sampling pump is closed by controller and starts alarm system, can so protect sampling pump, and
When prompting operating personnel sampling pump is safeguarded.
4th, the time that timer triggers capacitive approach switch is set to carry out timing on the utility model controller, very
Zhong Houcai closes sampling pump, starts alarm system, is that sampling pump extraction flue gas flue gas flow at initial stage is very few in order to prevent or samples
Pump false alarm caused by temporary plug, convenient operation.
5th, controller uses PLC controller in the utility model, facilitates programming Control.
