Description
Technical field
The utility model relates to detection technique, particularly a kind of combustor control system of direct control gas quantity.
Background technology
At present; Control to the boiler output size mainly realizes through dual mode: first kind is to utilize present weather compensation control system, through gathering boiler water-in and water-out temperature and coming the size of the actual firepower of control combustor indirectly via the original controller of boiler; Second kind is through installing a thermal source controller additional; This controller achieves a butt joint and communication with the part electric wiring of the control combustor firepower size of the original controller of boiler, controls the size of combustor firepower again via the different opening of the electric butterfly valve on the gas valve group.
Above dual mode cuts both ways.It is more convenient that first kind of control mode operates, and need not transform the inner electric wiring of original boiler controller, but the real-time of firepower control is not strong, and certain hysteresis quality is arranged.The real-time that second method boiler firepower is controlled is better, but needs to transform the inner electric wiring of original boiler controller, implements comparatively trouble, and is also higher to technical staff's level requirement.
In addition, there is a common defects in this dual mode, controls the combustion gas air inflow exactly and adopts electric butterfly valve, because the valve characteristic curve of electric butterfly valve is to change up closing property soon, so under the situation of various inlet amount, the ability of regulating continuously is relatively poor.That is to say; The theoretical air inflow that corresponding actual air inflow is set with the controller expection under different opening has than big-difference; This point can cause actual the exerting oneself of combustor may be discontented with the needs of pedal system heat supply; The glut that perhaps causes heat does not all reach the effect of " heating according to need " of expectation.For reasonable, the energy-saving run of combustor, need especially accurately to control the actual automatic control system of exerting oneself of combustor.
The utility model content
The purpose of the utility model is exactly the above-mentioned defective that will overcome prior art, a kind of size that can accurately control the combustor firepower in real time is provided, the combustor control system of the direct control gas quantity of good energy-conserving effect.
For reaching above-mentioned purpose; The combustor control system of the direct control gas quantity that the utility model provides comprises the some electric control valves that are installed on the gas valve group; Also comprise outdoor meteorological sensor and Programmable Logic Controller and Switching Power Supply, Programmable Logic Controller is connected with touch-screen display, and it is outdoor that outdoor meteorological sensor is installed in heating area; The detection signal of its collection exports Programmable Logic Controller to; Programmable Logic Controller is a PID controller, and it is connected to each electric control valve with the meteorological data of outdoor meteorological sensor collection with the valve opening control signal that data compare back output is set, and Switching Power Supply is that Programmable Logic Controller is supplied power with touch-screen display.
The utility model is directly controlled the combustor control system of gas quantity, and wherein said outdoor meteorological sensor comprises outdoor temperature sensor, outside humidity sensor and outdoor air velocity transducer at least.
The utility model is directly controlled the combustor control system of gas quantity, and wherein said valve opening control signal comprises gas control valve aperture control signal and gas control valve aperture control signal at least.
The utility model is directly controlled the combustor control system of gas quantity, and wherein said Switching Power Supply is output as 24V/2.2A.
The advantage that the utility model is directly controlled the combustor control system of gas quantity is: owing to be provided with outdoor meteorological sensor, Programmable Logic Controller and electric control valve; Realize the precise real-time control of combustor firepower size adjustment, thereby reached the energy-saving effect of expection.
Description of drawings
Fig. 1 is the block diagram that the utility model is directly controlled the combustor control system of gas quantity;
Fig. 2 is the wiring schematic diagram that the utility model is directly controlled the combustor control system of gas quantity.
The specific embodiment
Specify the combustor control system implementation example that the utility model is directly controlled gas quantity below in conjunction with accompanying drawing.
With reference to Fig. 1, the combustor of the direct control gas quantity that the utility model provides control system comprises the some electric control valve V that are installed on the gas valve group, outdoor meteorological sensor W and Programmable Logic Controller C and Switching Power Supply Y.Programmable Logic Controller C is connected with touch-screen display X, is convenient to operating personnel and controls on the spot.Switching Power Supply Y is output as 24V/2.2A, is Programmable Logic Controller C and touch-screen display X power supply.
In conjunction with reference to Fig. 2, outdoor meteorological sensor W comprises outdoor temperature sensor TA, outside humidity sensor TB and outdoor air velocity transducer TC at least, and it is outdoor to be installed in heating area respectively.The detection signal that outdoor meteorological sensor W gathers exports Programmable Logic Controller C to; Programmable Logic Controller C is a PID controller, its meteorological data that outdoor meteorological sensor W is gathered with the valve opening control signal that data compare back output be set be connected to each electric control valve V.The valve opening control signal comprises gas control valve aperture control signal TE and gas control valve aperture control signal Z3 at least.
Newly-built system or modernization system to a combustor heat supply; Earlier outdoor pressure regulating box is adjusted or adopted to the supply pressure of combustion gas; Overcome the pressure loss, promptly can adopt the combustor control system of direct control gas quantity, control mode employing ratio is regulated and is got final product.Meteorological sensor outside outdoor suitable position installation room can be gathered information such as sleet and wind speed rain or shine, and the electric butterfly valve on the gas valve group is replaced by electric control valve.
Programmable Logic Controller C gathers outdoor comprehensive meteorologic parameter as input signal; With reference to Fig. 2; In the combustor control system implementation example of the direct control gas quantity that the utility model provides; Gather signal by temperature sensor TW, regulate the tolerance that gets into combustor, directly the accurately continuous variation of control gas quantity through the electric control valve V on the control valve group.Programmable Logic Controller C realizes accurately being controlled by real-time outdoor temperature the caloric value of boiler through open loop control.Like this; Both eliminated the hysteresis drawback of regulating combustor firepower size through the Inlet and outlet water temperature of indirect control boiler; Also eliminated the problem of the continuous regulating power difference of electric butterfly valve under the situation of various inlet amount; Realize boiler accurately real-time control of control combustor firepower size under the comprehensive meteorologic parameter condition outside different chamber, guaranteed wind, gas ratio under the corresponding aperture, be implemented in the abundant burning of combustion gas in the efficient firepower scope.
