Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
The step of Fig. 2 is the utility model running figure.
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.
A kind of biomass gas burner of real-time detection biogas combustion position, according to Fig. 1, the utility model packet
Burner body has been included, there is the combustion chamber for directly burning for burning gases, the burner in the burner body
Ontology is provided with and the air supply pipe of combustion chamber, offgas duct；Burner body control connection one central controller of setting and
PLC, the central controller and PLC are electrically connected.
The combustion chamber is interconnected with the device for biomass by air supply pipe, and combustion gas master is provided on the air supply pipe
Combustion gas main valve on valve, the central controller and air supply pipe is electrically connected；
Supply valve is provided in the offgas duct, the supply valve in the central controller and offgas duct is electrically connected, institute
It states and is provided with carbonomonoxide concentration detector and oxygen amount detector by the side of supply valve, the utility model increases using tail gas
Add carbonomonoxide concentration detector and oxygen amount detector, by the information feedback to central controller of real-time detection, is converted by PLC
Signal is executed, according to the tail gas oxygen concentration and carbonomonoxide concentration of setting, is automatically adjusted and by control air supply pipe
Combustion gas main valve makes to enter indoor air capacity of burning, reaches and be precisely controlled burning oxygen amount.While in order to guarantee that biogas can
Reach completely burned, when biogas burns in the combustion chamber, combustion can constantly be detected according to the detection of tail gas oxygen amount and carbon monoxide
The situation of burning is converted into the supply valve in offgas duct after then being fed back by information to central controller and by PLC logic analysis
Order is executed, after ensure that biogas completely burned, which can just be supplied away, reach completely burned and excess air
It effectively adjusts, improves the efficiency of combustion of biogas, reduce the imperfect combustion of combustible.
The utility model tail gas can be made up of after sampling analysis burning carbonomonoxide concentration detector and oxygen amount detector
The concentration data of component finds out optimal tail gas oxygen content between minimum oxygen content, minimum amount of nitrogen oxides and completely burned
Ratio, and can be set in the control system of central controller according to this value.
In the implementation case, it is provided with flame detector in the combustion chamber, is provided with igniter in the combustion chamber,
Before combustion gas main valve open, igniter can first light a fire, after combustion gas main valve open, for i.e. flammable after biogas to combustion chamber
It burns, and whether flame detector can detect the indoor biogas of burning and burn, if igniter fire fails or is burning
Stop working suddenly in the process, which will transmit a signal to central controller, be converted into execution signal by PLC, control combustion gas
Main valve is closed, and the supply of biogas is cut off, and reaches the requirement of automatic adjustment, realizes automation.It is lagged before solving
Slow manual adjusting operation's mode, not only accurately, but also fast and flexible, save manpower and labor intensity.
The specific operation principles of the utility model are as follows:
Shown according to fig. 2 the step of figure, igniter is lighted, central controller is converted to by PCL to be executed signal and open air supply pipe
Interior combustion gas main valve, for directly burning in biogas to combustion chamber, it is indoor constantly to detect burning for flame detector at this time
Combustion position, if igniter fire fails or stops working suddenly in combustion, which will be transmitted a signal to
Central controller, then execution signal is converted by PLC, control combustion gas main valve is closed, and the supply of biogas is cut off；When ensuring
After biogas successfully maintains gas supply to burn, the carbonomonoxide concentration detector and oxygen amount detector are by the information of real-time detection
It is again sent in central controller, by being converted into execution signal after PLC logic analysis, and according to the tail gas oxygen concentration of setting
It is automatically adjusted with carbonomonoxide concentration and enters indoor air capacity of burning, reached after being precisely controlled burning oxygen amount, open offgas duct
Interior supply valve, heat is supplied away.Reach automatic combustion adjusting requirement, increase adjusting accuracy and flexibly
