双轴双碟烟道截止阀
普遍现状：
目前窑尾锅炉烟气旁通阀为：百叶电动阀。由于受传动轴影响阀座无法形成一个整体，阀板单薄，无法对阀门密封面进行精密加工，在实际使用中关闭不严，漏烟气量大，在高温烟气中易产生变形，造成卡死，开闭不灵活现象。由于大量高温烟气的泄露，造成进入余热锅炉的热量至少减少5%，浪费了大量余热发电可利用的热能。
Currently, the boiler flue gas bypass valve at kiln tail is the blinds electric valve. The valve seat cannot be formed integrally on account of the impact of transmission shaft, valve plate is so thin that valve sealing surface unable to be processed precisely. The valve is closed lax in practical use, leaking large flue gas. It is easy to deform in high temperature flue gas, causing stuck and closing inflexible. Since a large number of high-temperature flue gas leaked, causing the heat into the waste heat boiler to reduce at least 5%, wasting a lot of available heat energy utilized by waste heat power generation.
技术方案：
将现有的烟道阀拆除，更换具有发明专利的双轴双碟烟道截止阀。提供一种新型结构，使阀门关闭严密，开闭灵活，耐高温，阀板不变形，运行可靠，泄露小于1%。从而使高温烟气完全进入余热锅炉，使余热能充分利用，增加余热发电的效益。专利号：2014206207218。
方案优点：
1、本发明的双轴双碟烟道截止阀在设计上充分考虑了窑尾烟气的含尘量大，在完全关闭时也不积灰，克服了目前的烟道阀在开启时，积灰进入高温风机引起风机调停，造成事故。
2、同时可以为水泥企业提高吨熟料发电量1.5度，增加企业效益。
Remove the existing flue valve, and replace with a double-axis-dish flue shutoff valve with patent. Provide a new structure of the valve with the characteristics of a tight closure, opening and closing flexible, high temperature resistance, valve plate undeformed, perform reliably, and leak less than 1%. The high-temperature flue gas thereby access into the waste heat boiler completely, so that the waste heat can fully utilize and increase the effectiveness of Waste Heat Generating Electricity. Patent Number: 2014206207218.
1、The invention of double-axis-dish flue shutoff valve is designed to take full account of the large dust of flue gas at kiln inlet, nor fouling when fully closed, overcome the weakness of the existing flue valve likely to have accidents, caused by ash deposition enter high-temperature fan blower to make it mediation when the flue valve is open.
2、While it can improve 1.5 degree generating capacity of per ton of clinker for cement enterprises, and increase enterprise benefits.
