摘要: 针对目前加热炉余热回收冷风旁通风道调节挡板及烟道旁通密封挡板存在的内漏和开关、调节不够灵活问题,从传动机构、板叶密封等环节进行改进和完善,采用四连杆平行接触软密封的方式实现了挡板的几近零内泄漏。另外,在挡板阀的控制方式方面,在单个挡板上,同时集成了密封和调节功能,使其能够兼顾调节阀对叶片打开角度的精确控制和密封阀对控制信号的快速响应,以满足现场工艺需求。

Abstract: In view of the internal leakage and inflexible switch and adjustment of the air bypass damper and flue bypass damper of the fired heater waste heat recovery system, this paper improves and perfects the drive mechanism, blade seal, and adopts the four-bar linkage parallel contact soft seal to realize near-zero internal leakage of the damper. In addition, in terms of the control mode, the sealing and regulating functions are integrated on one damper, it can accurately control the regulating blades at the opening angle and the rapid response of the sealing blades to the on-off signal, so as to meet the on site process requirements.
