Description
Technical field
The present invention relates to boiler of power plant flue gas waste heat recovery and using field, a kind of water-borne formula teflon heat exchanger is applicable
Body tube board supporting structure.
Background technology
At present, the energy-conserving and environment-protective of coal-burning power plant of China require it is increasingly severe, after coal-fired plant boiler deduster exhaust gas temperature compared with
There is higher recycling to be worth for height, the partial heat.Teflon heat exchanger can be carried out because of its corrosion resistance characteristic to flue gas
Deep temperature reduction, greatly improve recovery heat.
Most of water-borne formula teflon heat exchanger uses suspension type supporting construction.Traditional supporting construction tube sheet support exists
Above structural beams, cause dead band of a part of heat exchanger tube between structural support beam, be not involved in exchanging heat.To ensure heat transfer effect,
Heat exchange area need to be increased, causes heat exchanger investment to increase.
The content of the invention
The present invention provides a kind of teflon heat exchanger body tube board supporting structure rational in infrastructure, and energy maximum effectively utilizes
Teflon heat exchanger exchange capability of heat, there is good sealing, prevent the corrosion of flue gas heat exchanging device external structure.
Technical scheme is realized as follows：A kind of water-borne formula teflon heat exchanger body tube sheet support knot
Structure, it is characterised in that it includes support beam, support beam reinforcing plate, fixed bolt, gasket seal, wallboard, anti-corrosion cornerite.It is described
Support beam is square steel or H type shaped steel, and material is general structural steel, and support beam lower flange side protrudes, in cantilevered structure, for propping up
Support teflon heat exchanger body tube sheet；The reinforcing plate is located in support beam between lower flange, in being equally spaced, spacing 150~
300mm, for increasing, structural beams are counter-bending, anti-torsion ability；The fixed bolt is full thread stud, and stud uses plug welding type
Formula is fixed on support beam lower flange, and plug welding hole is borehole pattern；The gasket seal is polytetrafluoro pad, be arranged in tube sheet with
Between support beam, conduct oneself with dignity by teflon heat exchanger body and be pressed and sealed pad.The wallboard is teflon heat exchanger housing wall
Plate, wallboard use non-corrosive metal (NCM) wallboard or inside lining anti-corrosive material, can effective sealing fume, prevent smoke spillage.The anti-corrosion bag
Angle is two-phase stainless steel sheet, is arranged on support beam lower flange end, for completely cutting off flue gas, prevent support beam lower flange end with
Smoke contacts and corrode.
The present invention will be further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
