Multi-effect siphon phase-change circular heat transfer system

Abstract

The invention discloses a multi-effect siphon phase-change circular heat transfer system, belongs to closed boiler heat supply systems, and relates to a boiler heat tube system, a mechanical siphon phase-change circular heat transfer system and a closed condensate water recovering system; intelligent multi-effect siphon condensate water and steam recovering machines are mounted on condensate water passages; the system is selectively equipped with a net-in device and gathering steam traps by a hot process; a traditional trap is eliminated; a gathering drain controller is used as a safety device; a compound storage tank is used for separating resurgent vapor efficiently; a special pump resists high temperature, prevents cavitation and remains seal; condensate water is recovered to a boiler through pump siphon; the resurgent vapor is recovered to be used stage by stage through exhaust stream backpressure/stream-jet siphon; continuous variable-flow water delivery is carried out to adapt to the variable working condition; the intelligent control is achieved; the condensate water is smoothly transferred; no waste heat is discharged; phase-change circular operation is realized to an isobaric/anisotonic boiler heat supply system, so that the isobaric/anisotonic boiler heat supply system becomes a real closed recovery system, and the energy saving and emission reducing effects are excellent. If waste heat is recovered to non-pressure equipment such as a deaerator/softened water tank to be heated, the pump is not used. The remote control operation is carried out through an operation platform of an internet of things.

Description

Technical field: [0001] The invention relates to a boiler as an evaporator, a partition-type heat-using equipment as a condenser, and a phase-change circulation heat transfer system in a closed system of working fluid, which relates to a boiler heating system, a separated heat pipe system, a boiler heat pipe system, mechanical Siphon phase change cycle heat transfer system. Background technique: [0002] "Separate Heat Pipe Heating System Complete Technology" (Patent No.: 91103204.5) and "Separate Heat Pipe Heating System in Series" (Patent No. 910202738.X) both use the pressure generated by the drop to return the condensate, which can only be applied to simple pressureless Boiler heating system, for the pressurized steam boiler heating system, there are many technical difficulties in the fully enclosed reflux of condensate. For example, the increase of the hydrophobic back pressure reduces the hydrophobic capacity, which affects the heat transfer of the process, and is pro...

Problems solved by technology

In addition, most of the existing small and medium-sized boiler heating systems have not entered the technical field of closed phase change cycle heat transfer, and continue to use open hot water storage tanks and hot water pumps to recover condensed water, and flash evaporation loses most of the waste heat , low recovery rate

What's more, there are still many small and medium-sized boiler heating systems that are still open to discharge condensed water, and the waste heat is extremely wasteful.
