Example Embodiment

[0028] Example 1

[0029] like figure 1 As shown, the separating heat pipe is used to recover the condensed heat-saving suspension bridge main cable composite dehumidification system, including: dehumidifier 6, wet air treatment system, regenerative air system, and condensation recovery system.

[0030] The dehumidifier 6 is used to provide dry air to the hospent bridge main cable, and the dehumidifier includes treatment zone 7 and regeneration zone 8.

[0031] The wet air treatment system is used to cool down the wet air entering the dehumidifier treatment region 7, and the wet air treatment system includes an evaporator 3, a compressor 21, and a condenser 24, a condenser outlet connection to the condenser. The condensate inlet of the unit, the water vapor outlet of the evaporator 3 connects the compressor 21, and the compressor 21 connects the steam inlet of the condenser 24. In the main circuit of the wet air treatment system, the wet air is condensed by the evaporator 3, and t...

Example Embodiment

[0043] Example 2

[0044] like figure 2 As shown, the difference from the first embodiment is that the condensation heat recovery system is connected to the inlet of the wet air treatment system by the bypass line 31, providing low temperature and low moisture air in the wet air treatment system. The air in the condensation heat recovery system is cooled, and after condensation, the air is formed, and the fan 28 is supplied with a low temperature and low moisture air discharged from the condensed heat recovery system to a wet air treatment system, which reduces the wet air treatment system to air. Cold and dehumidification requires the amount of cooling.

[0045] The first three-way valve 32 is mounted on the bypass line 31, and the bypass line 31 is connected to the line between the first temperature and humidity sensor 2 and the evaporator 3. The second single-way valve 33 is attached to the upstream line of the first initial effect filter 1.

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...
