Embodiment 1

[0047] Embodiment 1: If the tobacco leaf currently produced is B1F, the flow rate of the production line is 6000kg / h, and the ambient humidity is 60%. At this time K 1 = 0.7 (upper smoke), K 2 =0.8(4000kg / h≦Flow≦8000Kg / h), K 3 =0.9 (70%≧humidity≧50%).

[0048] Inverter fan setting frequency = K 1 *K 2 *K 3 *50HZ=0.7*0.8*0.9*50HZ=25.2HZ,

[0049] At this time, the inverter outputs light load.

Embodiment 2

[0050] Embodiment 2: For the tobacco leaf X3L currently produced, the flow rate of the production line is 12000 kg / h, and the ambient humidity is 45%. At this time K 1 = 1.0 (lower smoke), K 2 =1.0 (greater than 8000Kg / h), K 3 =1.0 (when the humidity is less than 50% K 3 = 1.0).

[0051] Inverter fan setting frequency = K 1 *K 2 *K 3 *50HZ=1.0*1.0*1.0*50HZ=50HZ,

[0052] At this time, the frequency converter outputs at full load.

[0053] Remarks: When the tobacco leaf flow rate is 0kg / h, that is, when the production line is running empty, the control system will stop the operation of the environmental dust removal air by delaying the shutdown for a certain period of time.

[0054] The frequency adjustment method of the frequency converter of the dust removal fan in the tobacco leaf production line provided by the embodiment of the present invention is based on the preset value set for different tobacco leaf grades, tobacco leaf flow rates, and environmental humidity. ...

Abstract

The invention provides a frequency adjustment method of a dust removing fan frequency converter in a tobacco production line. The frequency adjustment method of the dust removing fan frequency converter in the tobacco production line comprises the steps that according to the grade of tobacco, the value of a tobacco grade coefficient K1 is determined; according to the tobacco production flow of thetobacco production line, the value of a tobacco flow coefficient K2 is determined; according to the environmental humidity of a dust removal area, the value of an environmental humidity coefficient K3 is determined; and according to the values of the tobacco grade coefficient K1, the tobacco flow coefficient K2 and the environmental humidity coefficient K3, the output frequency of the dust removing fan frequency converter is adjusted, the computational formula is V=K1*K2*K3*50Hz, wherein V is the output power of the dust removing fan frequency converter. By the adoption of the frequency adjustment method of the dust removing fan frequency converter in the tobacco production line, through adjustment of the values of the tobacco grade coefficient K1, the tobacco flow coefficient K2 and an environmental humidity coefficient K3, the output frequency of the dust removing fan frequency converter is changed, so that dust in the tobacco production line can be effectively processed, and the dust removal energy consumption can be lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco production technology, in particular to a method for adjusting the frequency of a frequency converter of a dust removal fan in a tobacco leaf production line. Background technique [0002] The main function of the environmental dust removal section of the tobacco rebaking production process line is to realize the treatment of the dust generated in the tobacco leaf production process so that it can meet the dust emission standards. [0003] In the production of tobacco leaves, the grades of the incoming tobacco leaves are different, that is, the parts of the tobacco leaves are different, and the dust content is different. The upper tobacco leaves had the least amount of dust, followed by the middle tobacco leaves, and the lower tobacco leaves had the largest amount of dust. Different air humidity also has different effects on dust, and different flow rates of production lines have different requir...
