Fly ash dryer in the work, will produce a large amount of exhaust gas, need to use the dust removal equipment will be the rational use of exhaust gas, to minimize the harm to the environment. As an operator, to learn to calculate the amount of exhaust gas, to reasonably select the model of dust removal equipment and the entire dust removal system.

The coal slurry dryer equipment will emit a certain amount of exhaust gas in the process of drying materials, and the formula for calculating the amount of exhaust gas from the fly ash dryer equipment is as follows: V=W(ι+1/rw)

In the formula: V is the amount of exhaust gas from the dryer equipment, m3/h;

w is the amount of water evaporated by the dryer, kg water/h;

ι is the volume of hot gas needed to evaporate the water from the dryer, m3/h;

ι is the volume of heat gas needed to evaporate water from the dryer, m3/h. Hot gas volume, m3/kg water;

rw is the water vapor gravity, kg/m3, rw=0.805kg/m3.

According to this calculation method, the configuration of the dust removal system can be quickly calculated. Zhengzhou Huachang Machinery Manufacturing Co., Ltd. is a professional sand dryer, coal sludge dryer, desulfurization gypsum dryer, rotary dryer, chain plate dryer manufacturer, according to the characteristics of the material, for you to configure the most reasonable whole coal sludge drying production line.
