Example Embodiment
[0035] Example 1
[0036] 1. Using high negative pressure fan and large air volume fan
[0037] (1) Two main exhaust fans:
[0038] Air volume: 19800m 3 / min(working condition)
[0039] Negative pressure at the fan inlet: 16500Pa
[0040] Air volume per unit sintering area: Q=2×19800 / 360=110m 3 / (m 2 ·Min)
[0041] (2) The head electric dust collector
[0042] In response to the strict requirements of high negative pressure fans for dust concentration, two sets of 330m are adopted through the design 2 Horizontal three-electric field electrostatic precipitator, which can reduce the dust concentration of flue gas to 80mg / m 3 Below, protect the smoke machine rotor.
[0043] The following Table 1 lists the technical performance indicators of the high negative pressure equipment used in Embodiment 1 of the present invention.
