Temperature reduces, and flame increases, and temperature raising, flame reduces, and combustion gas can burn insufficient when flame reduces.It is clean-burning
When, blue is presented in flame, and during burn incompletely, flame presents red.When temperature is excessively high, air needed for combustion gas into
Tolerance is reduced, and then insufficient that temperature is controlled to reduce, the temperature control precision of such control mode is relatively low, while natural gas
There are wastes.
Utility model content
The technical issues of to solve in above-mentioned background technology, the utility model provide a kind of combustion gas cut-tobacco drier and dry silk temperature
Closed-loop control device and the method measured using this device to pipe temperature, the device and method can be by existing interruptions
Property flame become uniform, steady and continuous firepower, can more accurately control combustion furnace hot air temperature, while reduce natural
The consumption of gas.
Specifically, a kind of combustion gas cut-tobacco drier described in the utility model dries silk temperature closed-loop control device, feature exists
In including temperature sensor, PID controller and injection apparatus actuator；Wherein,
The temperature sensor is for acquiring temperature data in pipeline, and by collected temperature data and setting value ratio
Compared with, obtain difference, by the differential transmission give the PID controller；
The PID controller is used to a regulated value be calculated, and be based on based on difference progress proportional integral differential
The regulated value controls the injection apparatus actuator；
The injection apparatus actuator is used to carry out flame action according to the regulated value.
In the present embodiment, when temperature data and setting value are without difference, PID controller attonity is inessential so as to reduce
Flame action, efficiently reduce the waste of natural gas.
In the present embodiment, the period of temperature sensor sensing temperature is 500ms, makes temperature control more accurate, igniting
It acts also evenly.
Description of the drawings
Fig. 1 dries silk temperature closed-loop control device schematic diagram for combustion gas cut-tobacco drier described in the utility model
Specific embodiment
With reference to embodiments and the technical solution of the utility model is described in detail in respective drawings, so that this field
Technical staff can be more clearly understood the embodiment of the utility model, but and be not so limited the protection model of the utility model
It encloses.
Negative feedback closed loop control principle is made the difference, obtained value by the real-time collecting temperature of temperature sensor with setting value sp
PID controller is inputted, is calculated by proportional integral derivative, obtains deviation, air jet system actuator is controlled using deviation,
Proportional action can be quickly close to setting value, and integral action can eliminate steady state error, accurately tracks desired temperature, and differential is made
With can eliminate pulse ripple, reduce the external disturbance transmitted suddenly of temperature sensor.Utilize the temperature sensing of original system
Device, air jet system actuator and increased PID controller form a close loop negative feedback control loop.The temperature of original system first
The gathered data time is 3S, and flame is intermittent eruption, and the precision of temperature is controlled using discontinuous firepower size is controlled.Collection point
The overlong time in degeneration factor, is revised as 500ms, will read temperature sensor data and setting automatically per 500ms systems
Value makes the difference, and by deviation to PID controller, obtains actuator by proportional integral differential and exports, actuator is adjusted according to output
Section, is zero after being made the difference with setting value when temperature sensor does not have deviation, and into PID without output valve, actuator is motionless
Make.Close loop negative feedback is exactly to have deviation just to have adjusting, zero deflection is not just adjusted come adjusting actuator using deviation.It controls in this way
Precision is considerably improved.
The utility model provides a kind of combustion gas cut-tobacco drier and dries silk temperature closed-loop control device and using this device to pipeline
Existing discontinuity flame can be become uniform, steady and continuous firepower by the method that temperature measures, the device and method,
Combustion furnace hot air temperature can be more accurately controlled, while reduces the consumption of natural gas.
Specifically, combustion gas cut-tobacco drier described in the utility model, which dries silk temperature closed-loop control device, includes temperature sensing
Device, PID controller and injection apparatus actuator；The PID controller is coupled with injection apparatus actuator, based on according to PID
Data after calculation are adjusted using injection apparatus actuator into trip temperature；The temperature sensor is set in cut-tobacco drier pipeline, and
It is coupled with PID controller, for the temperature data that temperature sensor is collected into be sent in PID controller.It is born by closed loop
Feedback Design using bias adjustment injection apparatus actuator, is greatly improved control accuracy, and reduce when deviation is not detected
Flame acts, and is effectively reduced the consumption of natural gas.
The method of silk temperature closed-loop control device measurement temperature is dried using combustion gas cut-tobacco drier, this method includes the following steps：
1) temperature data in temperature sensor acquisition pipeline, and relatively and obtain difference with setting value；2) by the differential transmission to described
In PID controller, and pass through proportional integral differential and obtain a regulated value；3) injection apparatus actuator is sprayed according to regulated value
Fire action.Close loop negative feedback is configured to using a PID controller is increased, spray is controlled using the deviation of setting value and actual value
The actuator aperture of device of air so that temperature control precision increases substantially.Firepower will more uniformly simultaneously, combustion of natural gas
More fully, the processing quality of product is promoted while reducing natural gas consumption.
In the present embodiment, when temperature data and setting value are without difference, PID controller attonity is inessential so as to reduce
Flame action, efficiently reduce the waste of natural gas.
In the present embodiment, the period of temperature sensor sensing temperature is 500ms, makes temperature control more accurate, igniting
It acts also evenly.
It the above is only and the preferred embodiment of the utility model is described, not by the technical side of the utility model
Case limited to this, any known deformation that those skilled in the art are made on the basis of the major technique design of the utility model
The claimed technology scope of the utility model is belonged to, the specific protection domain of the utility model is with the record of claims
