Embodiment 1

[0029] Such as figure 1 As shown, the suspension bridge main cable composite dehumidification system using separate heat pipes to recover condensation heat includes: dehumidification runner 6, wet air treatment system, regeneration air system and condensation heat recovery system.

[0030] The dehumidification rotor 6 is used to provide dry air to the main cable of the suspension bridge, and the dehumidification rotor includes a treatment area 7 and a regeneration area 8 .

[0031] The wet air treatment system is used to cool and condense the humid air entering the dehumidification wheel treatment area 7. The wet air treatment system includes an evaporator 3, a compressor 21 and a condenser 24 connected in sequence, and the condensate outlet of the condenser is connected to the evaporation The condensate inlet of the evaporator, the water vapor outlet of the evaporator 3 is connected to the compressor 21, and the compressor 21 is connected to the steam inlet of the condenser 2...

Embodiment 2

[0044] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the condensation heat recovery system is connected to the air inlet of the humid air treatment system through a bypass line 31 to provide low-temperature and low-humidity air for the humid air treatment system. The air in the condensation heat recovery system is cooled and condensed by the separate heat pipe evaporation section 26 to form low-temperature and low-humidity air, and the fan 28 supplies the low-temperature and low-humidity air discharged from the condensation heat recovery system to the humid air treatment system, reducing the impact of the wet air treatment system on the air. Cooling capacity required for condensation and dehumidification.

[0045] A first three-way valve 32 is installed on the bypass pipeline 31 , and the bypass pipeline 31 is connected in parallel on the pipeline between the first temperature and humidity sensor 2 and the evaporator 3 . The upstr...

Abstract

The invention provides a suspension bridge main cable composite dehumidification system for recovering condensation heat through separated heat pipes. The suspension bridge main cable composite dehumidification system comprises a dehumidification rotating wheel, a humid air treatment system used for cooling and condensing humid air entering the dehumidification rotating wheel treatment area and comprising an evaporator, a compressor and a condenser, a regeneration air system which supplies heat to air flowing into a regeneration area of the dehumidification rotating wheel and comprising a separation type heat pipe condensation section for preheating the air, an electric heater and a regeneration fan, and a condensation heat recovery system that provides steam for the separation type heat pipe condensation section of the regeneration air system; and the separation type heat pipe evaporation section, a steam ascending pipe, the separation type heat pipe condensation section, a liquid descending pipe and a separation type heat pipe evaporation section of the condensation heat recovery system are sequentially connected to form a circulation loop. The system is large in dehumidification amount, low in rotating wheel dehumidification dew point temperature, high in condensation heat grade, large in heat, good in separated heat pipe heat transfer performance, convenient to arrange and high in environmental adaptability.

Description

technical field [0001] The invention belongs to the technical field of bridge dehumidification, and in particular relates to a composite dehumidification system for main cables of a suspension bridge using separate heat pipes to recover condensation heat. Background technique [0002] The main cable is one of the main stress-bearing components of the suspension bridge. During the design life of the bridge, the main cable is a non-replaceable structure. Therefore, how to protect the durability of the main cable structure is very important. The traditional main cable protection system prevents moisture from intruding into the interior of the main cable by sealing and wrapping the outer layer of the main cable to achieve the purpose of anticorrosion, but there are still problems such as the inability to eliminate construction residual water, aging and cracking of protective materials, construction methods and equipment restrictions, etc. Cause anticorrosion target to be difficu...
