Described winding-up short tube mouth is 160mm-180mm apart from the height of card.
Under the state of middle pressure (0.3MPa-0.5MPa) winding-up, injection tube is divided into the anterior and winding-up rear portion of winding-up, the nozzle diameter of injection tube front portion is dmm, the nozzle diameter at injection tube rear portion is (d-1) mm, and all nozzle diameter sums should be 60～80% of injection tube internal diameter on the injection tube.When compressed air stream enters injection tube along the winding-up mouth of pipe like this, near anterior large-minded, the mouth mouth is corresponding big, the closer to the injection tube rear portion, throughput is more less than normal, need that jet hole is corresponding to be reduced, jet the compressed air stream that with the compressed air stream that guarantees to eject from the posterior nozzle group under almost identical jetting pressure with the anterior nozzle group of injection tube, guarantee the best ash-removal effect of injection system.
Winding-up short tube mouth is also very important apart from the control of card height.The height of winding-up short tube end face distance card is subjected to air-flow to become the impact of 20 ° of angles and chain induction air quantity along the winding-up axis.In theory, chain induction tolerance is The more the better, just strengthens the winding-up short tube apart from the height of card.But height can not unrestrictedly be raised, and air-flow becomes the phenomenon of 20 ° of angular spread to be doomed that it can only be a definite value along the winding-up axis.This value can guarantee that just the original air-flow of diffusion enters filter pocket mouths together with the air-flow while supersonic speed of inducing.The air-flow moment that enters filter bag blows to the filter bag bottom, forms certain pressure in the filter bag bottom.Then, the air-flow recoil is upwards sharply expanded in filter bag, shakes off covering the dust stratification at the filter bag outer surface.
According to using the CAD Simulation result on computers, under the jetting pressure of 0.3Mpa, 3 cun pulse valves winding-up specification is 150 * 7100 filter bag, and it highly is: H=160mm; The filter bag of winding-up 160 * 7100, it highly is: H=180mm.
In fact, jetting pressure is more big, and air-flow is just more little along the diffusion angle of winding-up axis, and the height of winding-up short tube end face distance card just can strengthen, and induces more air-flows, the more filter bag of jetting; Otherwise jetting pressure is more little, and air-flow is just more big along the diffusion angle of winding-up axis, and the height of winding-up short tube end face distance card just need to reduce, and induced draft reduces relatively, and the quantity of winding-up filter bag reduces.
