复式挡板脱水器(国外英文资料) Double baffle dehydrator 1) role briefly Compound damper dehydrator after blocking dehydrator for short (or complex block foam), it is to belong to a kind of dc type cyclone, but within the device increased the number of concentric circles, as shown in figure 5-27. FIG. 5-27 baffle dewatering structure In a cyclone, the particle creates a synthetic cast line in both the tangent and the radial motion. Composite casting without baffle O - A to make the particles on the wall A collision, if increase the baffle, the casting will be truncated to point B, O - A shortened into O - B line, make the particles crashed landed at B in advance. The more concentric stops, the shorter the line, the more chance that particles will fall. It helps to improve the efficiency of particle removal. The trace of the cast line is shown in figure 5-28. China metallurgical industry network Figure 5-28 parabolic trajectory If the particle is a liquid, it falls on the wall and forms a membrane of water. If the film is too thick, it may spill the water again when it passes. After adding baffle, it is equal to increase the wall area of the wall, and the water film will be reduced, which will not cause the foam entrainment. In cyclone without damper, air circulation within the machine at least two to three times or more, with the outer spiral downward and upward spiral double column, the pressure loss is big. In the rehydrator, the air flow is only 3/4 laps in the shield and is at most a lap in the wall. Therefore, in the same imported gas velocity, the resistance is smaller than the backless reflector. Although add baffle will increase air flow and wall friction resistance, but the cyclone resistance from the main air flow transmission, and the wall friction resistance produced by the account for only a small part. The drawback of the backstop is that the fender material and make up, make the weight, the cost increase. Currently used after block diameter of about 300 to 2650 mm Φ
