The analysis is in industrial off-gas treatment the computation to wind force is what kind of

A lot of industry leaders do not know to need to handle air of how many processing to pollute control equipment. Alleged industry knows what market. Through industry of 10 years of off-gas treatment, the company will respond the wind force computation of equipment of industrial off-gas treatment! Above all, industrial off-gas treatment must understand the empty tolerance that the workshop produces, this is the crucial step that chooses off-gas treatment equipment. If wind force computation is bad, alternative of exhaust processing equipment is undeserved, will reduce exhaust to handle the effect greatly.

In process of industrial off-gas treatment, want to define the waste gas kind that the enterprise discharges above all. For example, the bases of waste gas is benzene, mellow, ketone, aldehyde or other gas. Should calculate first main gas, calculate according to content next. The gas that computation produces is measured. Next, be necessary to measure the length of space of enterprise exhaust emission, width and height, regard academic calculative as the foundation. The computational formula of wind force of industrial off-gas treatment uses method of two kinds of calculation extensively to have at present commonly: Actual measurement technique and academic method.

Actual measurement technique, reach measured value when exhaust emission namely when, q=q × B/b/10000, meaning of every abecedarian in formula. Ask: Year discharge capacity, with ” 10, 000 stere / year ” for the unit. Q: Horary exhaust emission is measured, unit ” Markm3/h ” . B: Year specific fuel consumption (or clinker crop) with ” Kg/y ” for the unit. B: The horary specific fuel consumption below normal circumstance (or clinker is produced) , with ” Kg/h ” for the unit

Opposite Yu Feng measures computational theory method in off-gas treatment, namely the computation of wind force is formulary, bulk of floor of shop of wind force = (long × wide × is tall) M3 × is ventilated and invariable (60-100) go up the invariable 60-100 in type is experience value. If the factory operates time weak point and useless tolerance is little, invariable and OK the choice is 60. If working hours is short and useless tolerance is little, invariable and OK choose 70-80. If working hours is long and useless tolerance is big, invariable and OK choose between 90-100.

Cite a simple case, in off-gas treatment if we want to handle length, width and height are 3 meters gush room, how should we determine wind force? Will treat the condition that aspiration room lays in ventilated mode above all. Have 3 kinds of pattern normally: The first kind is completely sealed, next according to afore-mentioned computation the method is correct, namely ventilated frequency of × of bulk of wind force = , namely 3 × of 3 × 3 × 60=1620m3/H. The 2nd kind is coping bleed cover, the smallest times of air replacement is 100, the times of air replacement when smoking arrives less 200. The 3rd kind is side bleed cover, the smallest times of air replacement is 150, the amount that the air when smoking changes is 300, this is accurate computational method.
