Description
技术领域technical field

背景技术Background technique
目前，我国燃煤电厂节能环保要求日趋严厉，燃煤电厂锅炉除尘器后排烟温度较高，该部分热量具有较高的回收利用价值。氟塑料换热器因其耐腐蚀特性，可以对烟气进行深度降温，大大提高回收热量。At present, my country's coal-fired power plants have increasingly stringent requirements for energy conservation and environmental protection. The exhaust gas temperature behind the dust collector of coal-fired power plant boilers is relatively high, and this part of the heat has a high recovery value. Due to its corrosion resistance, the fluoroplastic heat exchanger can deeply cool the flue gas and greatly improve the heat recovery.
大部分水媒式氟塑料换热器均采用悬吊式支撑结构。传统的支撑结构管板支撑在结构梁上方，导致一部分换热管位于结构支撑梁间的死区，不参与换热。为保证换热效果，需加大换热面积，导致换热器投资加大。Most water-borne fluoroplastic heat exchangers adopt a suspended support structure. The traditional support structure tube sheet is supported above the structural beams, resulting in a part of the heat exchange tubes being located in the dead zone between the structural support beams and not participating in heat exchange. In order to ensure the heat exchange effect, it is necessary to increase the heat exchange area, resulting in increased investment in heat exchangers.

The support beam is made of square steel or H-shaped steel, and the material is ordinary structural steel. One side of the lower flange of the support beam protrudes and is in a cantilever structure, which is used to support the tube plate of the fluoroplastic heat exchanger body; the reinforcement plate is located above and below the support beam. The flanges are equidistantly distributed with a spacing of 150-300mm, which is used to increase the bending and torsion resistance of the structural beam; the fixed studs are fully threaded studs, and the studs are fixed under the support beam by plug welding On the flange, the plug welding hole is a digging type; the sealing gasket is a polytetrafluoroethylene gasket, which is arranged between the tube sheet and the support beam, and the gasket is compacted and sealed by the weight of the fluoroplastic heat exchanger body.
