Detailed Description
As shown in fig. 1, a mixed-action induced draft fan structure for energy saving of a hazardous waste incineration system comprises an induced draft fan 1 for inducing air for the hazardous waste incineration system, a motor 3 for supplying power to the induced draft fan, and a turbine 5; a coupler 2 is arranged between the induced draft fan 1 and the motor 3, and the motor 3 is connected with the turbine 5 through a clutch 4; a steam outlet (not shown in the figure) of the hazardous waste incineration system is connected with a turbine 5; the motor 3 adopts a high-voltage alternating current asynchronous motor, the coupler 2 adopts an automatic hydraulic coupler, and the clutch 4 adopts an automatic clutch.
The energy-saving method for the hazardous waste incineration system in the technical scheme of the invention comprises the following steps:
s1: starting a hazardous waste incineration system;
s2: when the dangerous waste incineration line is just started, no steam is generated in the whole plant; at the moment, a motor 3 is adopted to drive the draught fan 1 to rotate;
a coupler 2 is arranged between the motor 3 and the induced draft fan 1; the motor 3 drives the coupler 2 to rotate, and the rotation of the body of the induced draft fan 1 is adjusted by adjusting the oil filling amount of the coupler 2;
the motor 3 is adopted to drive the coupler 2 to rotate, and the rotation of the induced draft fan body is adjusted by adjusting the oil charge of the coupler 2, so that the starting operation state of the whole incineration system is achieved; the coupler 2 is arranged between the motor 3 and the induced draft fan 1, so that the motor 3 is small in starting no-load current, and the impact load on a power grid is reduced;
s3: collecting steam output by the hazardous waste incineration system;
s4: the steam output by the hazardous waste incineration system drives a turbine 5 to rotate, and the turbine 5 and the motor 3 output power together for the induced draft fan 1;
s5, arranging a clutch 4 between the turbine 5 and the motor 3; when the output rotating speed of the turbine 5 reaches the rated rotating speed of the motor 3, the clutch 4 can be automatically combined with the motor 3, and the clutch and the motor can simultaneously apply work to the induced draft fan 1.
Because the turbine 5 continuously works, the load of the motor 3 is gradually reduced, and the electric energy consumption of the motor 3 is gradually reduced; steam output by the system is used for driving the turbine 5 to do work for the induced draft fan 1, so that the electric quantity consumption of the whole incineration system is effectively saved, and meanwhile, the waste heat steam resource is effectively recycled, and the energy conservation, emission reduction and green production are realized.
In order to further save energy, in practical application, an energy-saving standard value of the turbine can be set, namely, the turbine reaches the lower limit value of the lowest steam requirement under the condition of the rated rotating speed of the motor; the lowest starting limit value of the turbine 5 is that the turbine 5 can lap the motor 3 to supply power for the draught fan 1, and the energy-saving standard value of the turbine is set to be the lowest steam requirement limit value which ensures that the rated rotating speed of the motor 3 is reached;
s3-1: detecting the steam production capacity of the hazardous waste incineration system in real time, and determining whether the steam produced by the system reaches the energy-saving standard value of a turbine or not;
in the embodiment, the energy-saving standard value of the turbine is set as the amount of steam generated under the condition of 30-40% of the treatment capacity of the incineration system;
when the system processing capacity is larger than or equal to the preset turbine energy-saving standard value, executing step S4;
otherwise: the steps S2 to S3-1 are executed in a loop.
When the abundant steam meets the rated steam demand of the turbine 5, namely, the processing capacity of the turbine reaches the maximum working condition of the turbine, the output power of the motor 3 approaches to 0, and the induced draft fan 1 is completely powered by the turbine 5; the hybrid power supply time of the turbine and the motor is shortest, and the energy consumption of the system is further ensured to be minimum.
