Description
Technical field
The utility model relates to motor control assembly, relates in particular to the boiler accessory machinery control device that is applied in the cereal combustion boiler system.
Background technology
In paper industry, bigger to the consumption requirements of the energy.General paper industry is to utilize coal generation steam or generating as energy resource supply, because coal belongs to non-renewable resources, also environmental pollution is bigger relatively for its combustion tail gas.Therefore provide a kind of at needs and utilize that burning husk, tobacco rod, bamboo are cut, the cereal combustion boiler system of brush wood the like waste substitutes original coal energy resource supply, not only can energy savings, turn waste into wealth, can also reduce environmental pollution, and all right as fertilizer sources of these cereal comburants and other purposes can produce added economic value and make full use of resource.
In the cereal combustion boiler system, need control with energy savings consumption a plurality of boiler accessory machineries, increase the overall power factor of cereal combustion boiler system.
The utility model content
Therefore, the utility model just is based on the problems referred to above, proposes the boiler accessory machinery control device in a kind of improved cereal combustion boiler system, the cereal combustion boiler system can be maintained optimum state, has improved overall power output greatly.
The technical solution of the utility model is:
Boiler accessory machinery control device in the cereal combustion boiler system of the present utility model is: the power supply passage of remote control operation platform and control signal passage are connected to the first power frequency control device and first frequency-converting control device, the second power frequency control device and second frequency-converting control device, the 3rd power frequency control device and the 3rd frequency-converting control device, the described first power frequency control device and first frequency-converting control device all are electrically connected at air blast, the described second power frequency control device and second frequency-converting control device all are electrically connected at air-introduced machine, and described the 3rd power frequency control device and the 3rd frequency-converting control device all are electrically connected at feed pump.
Further, the described power supply passage power supply passage that is the 380V three-phase electricity.
Further, the described control signal passage control signal passage that is the CAN industrial bus.
The utility model adopts as above technical scheme, boiler accessory machinery control device in a kind of improved cereal combustion boiler system is proposed, can save the steam generator system energy consumption on the one hand, the power consumption that can save blower fan on the one hand, energy-saving effect is obvious, the cereal combustion boiler system is maintained optimum state, improved overall power output greatly.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
The specific embodiment
Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.
The major pant item of boiler is air blast and air-introduced machine, its operational factor is directly related with the thermal efficiency and the power consumption of boiler, with suitable speed adjusting technique, load according to boiler need be regulated air blast and air-introduced machine, keep boiler operatiopn at optimum, can save the steam generator system energy consumption on the one hand, on the one hand the power consumption that can save blower fan.
Consult shown in Figure 1, boiler accessory machinery control device in the cereal combustion boiler system of the present utility model is: the power supply path 10 1 of remote control operation platform 1 and control signal path 10 2 are connected to the first power frequency control device 211 and first frequency-converting control device 212, the second power frequency control device 221 and second frequency-converting control device 222, the 3rd power frequency control device 231 and the 3rd frequency-converting control device 232, the described first power frequency control device 211 and first frequency-converting control device 212 all are electrically connected at air blast 31, the described second power frequency control device 221 and second frequency-converting control device 222 all are electrically connected at air-introduced machine 32, and described the 3rd power frequency control device 231 and the 3rd frequency-converting control device 232 all are electrically connected at feed pump 33.The power supply passage that described power supply path 10 1 is the 380V alternating current.The control signal passage that described control signal path 10 2 is CAN industrial bus.Blower fan and water pumps all in the utility model adopt the configuration mode of (promptly a frequency-converting control device is joined a motor) one to one, and it is standby each other to keep former power frequency control device and frequency-converting control device, and regulative mode all adopts adjusted open loop.
The rotating speed of alternating current generator is directly proportional with accepting frequency, can reach the purpose of adjusting motor speed by the frequency of supply that changes motor.According to the operation principle of fluid transmission equipment (water pump, blower fan) as can be known: the flow of water pump, blower fan (air quantity) is directly proportional with its rotating speed; Square being directly proportional of the pressure of water pump, blower fan (lift) and its rotating speed, and the shaft power of water pump, blower fan equals the product of flow and pressure, so the shaft power of water pump, blower fan is directly proportional with the cube of its rotating speed (promptly being directly proportional) with the cube of supply frequency.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
