1st, dust-cleaning principle
1. dust-cleaning principle of the present invention mainly detaches gas, dirt using gas rotating centrifugal force, without clogging, according to
Gas centrifuge force formula：P=F/g*V2/ r, P are the centrifugal force of unitary gas, and V is the tangential velocity of gas, and r is tangential radii,
F is the weight of gas and water dirt, and to gas and water dirt, F=γ S, γ have been the proportion of gas and water dirt, and S is the volume of gas and water dirt, and g is weight
Power acceleration.Since dedusting gas is the mixture of dust, water, flue gas, very high tangential velocity is generated after impeller, by public affairs
Formula can be seen that the centrifugal force of rotary gas and the volume of substance, weight are directly proportional, square directly proportional to speed, water and powder

(V2 2-V1 2)/(2g), dp is the negative pressure value between two Guan Jing, and γ is the proportion of gas, and g is acceleration of gravity, V2、V1It is two pipes
The speed of diameter, when a caliber area increases exponentially, speed is reduced at double；In the case where another caliber is constant, speed
It is constant, by formula：∫ dp=γ (V2 2-V1 2)/(2g) as can be seen that the squared differences of the negative pressure value dp and speed between two tube sections
It is directly proportional, in speed V1 2Negative pressure value and V in the case of definite value2 2It is square directly proportional, since T-shaped pipe inlet -duct area is into multiplication
Greatly, the speed of gas into T-shaped pipe import reduces at double, and negative pressure value is reduced with the quadratic relationship of speed, and suction significantly reduces,
