Description
Technical field
The utility model relates to the gas-liquid gravity heat pipe heat exchanger, relates in particular to a kind of corrosion resistant gas-liquid gravity heat pipe heat exchanger.
Background technology
Heat pipe is a kind of heat transfer element with high heat-transfer performance, and it transmits heat through the latent heat of phase change of working media in the airtight vacuum shell, and the inside heat pipe medium receives thermal evaporation in bringing-up section, rise to top after, in radiating segment condensation heat release.The Heat Transfer of Heat Pipe on Heat Pipe performance classes is similar to the electric conductivity of superconductor, and therefore, it is big that it has heat-transfer capability, the characteristics that heat transfer efficiency is high.In conjunction with the finned tube technology, heat pipe often is used to the waste heat recovery in all kinds of flue gases, becomes the raising heater efficiency, and fuel saving consumption is the strongest means.
General gas-liquid heat exchange of heat pipe adds hot water to uniform temperature through heat pipe draw heat from smoke evacuation.Hot water can be used as water for industrial use, boiler feedwater, heating and other production, domestic water; The boiling water worker that can hold office drinks and produces use; This has just realized heat recovery.
But the thermotube wall material of traditional gas-liquid heat exchange of heat pipe is a carbon steel, and the water side is easier to take place corrosion failure behind the long-play, causes heat exchanger performance to descend and even inefficacy.Therefore be necessary its improvement, improve gas-liquid heat exchange of heat pipe water side corrosion resistance, increase the service life, practice thrift cost.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of corrosion resistant gas-liquid gravity heat pipe heat exchanger is provided.
For realizing above purpose, the utility model is taked following design:
Corrosion resistant gas-liquid gravity heat pipe heat exchanger comprises cuboid housing, central dividing plate, gravity assisted heat pipe; Central dividing plate is divided into water leg and flue gas chamber with the cuboid housing; And in central dividing plate, vertically be provided with many gravity assisted heat pipes; The first half of gravity assisted heat pipe is that condensation segment condensation segment inner tip scribbles the agent of incoagulable gas suction hydrogen, and the latter half of gravity assisted heat pipe is an evaporator section, and the evaporator section outer surface has fin.
The material of described evaporator section is a carbon steel pipe, and the material of condensation segment is a stainless steel tube.
The utility model is applied to gas-liquid gravity heat pipe heat exchanger water side to stainless steel, utilizes stainless good corrosion resistance, improves the corrosion resistance of gas-liquid gravity heat pipe heat exchanger water side, effectively prevents heat pipe failure, increases the service life.The gas-liquid heat exchange of heat pipe is made up of by certain arrangement mode many gravity assisted heat pipes, and the present invention transforms employed gravity assisted heat pipe, and evaporator section uses carbon steel as pipe wall material, and condensation segment uses stainless steel as pipe wall material.Incompatible for preventing heat pipe; The heat pipe inwall has carried out Passivation Treatment; Added corrosion inhibiter in the heat-pipe working medium, and scribbled the agent of incoagulable gas suction hydrogen, solved the molten steel consistency problem effectively through the composite tube wall steel-water heat pipe after handling like this in the condensation segment inner tip.The gas-liquid heat exchange of heat pipe that utilizes this steel-water heat pipe to combine, its water side has good anti-corrosion, and has only the water side to use stainless steel, and the gas side still uses carbon steel as material, thereby cost also is effectively controlled.Have corrosion resistance, efficiently operation for a long time preferably, and with low cost.

Fig. 1 is corrosion resistant gas-liquid gravity heat pipe heat exchanger structural representation;
Fig. 2 is the gravity assisted heat pipe structural representation of the utility model;
Among the figure: cuboid housing 1, water leg 2, dividing plate 3, gravity assisted heat pipe 4, flue gas chamber 5, evaporator section 6, fin 7, condensation segment 8, suction hydrogen agent 9.
The specific embodiment:
The contrast accompanying drawing further specifies the utility model.
Like Fig. 1, shown in 2; Corrosion resistant gas-liquid gravity heat pipe heat exchanger comprises cuboid housing 1, central dividing plate 3, gravity assisted heat pipe 4, and central dividing plate 3 is divided into water leg 2 and flue gas chamber 5 with the cuboid housing, and in central dividing plate 3, vertically is provided with many gravity assisted heat pipes 4; The first half of gravity assisted heat pipe 4 is a condensation segment 8; Condensation segment 8 inner tip scribble incoagulable gas and inhale hydrogen agent 9, and the latter half of gravity assisted heat pipe 4 is an evaporator section 6, and evaporator section 6 outer surfaces have fin 7
The material of described evaporator section 6 is a carbon steel pipe, and the material of condensation segment 8 is a stainless steel tube.
The course of work of the utility model is following:
High-temperature flue gas passes through from the gas side of heat exchange of heat pipe, and flue gas receives thermal evaporation with the heating of heat pipe one end at this bringing-up section inside heat pipe medium, and after medium rose to top, in water side (radiating segment) the condensation heat release of heat pipe, liberated heat added hot water to uniform temperature like this.The hot water that produces can be used as water for industrial use, boiler feedwater, heating and other production, domestic water; The boiling water worker that can hold office drinks and produces use; This has just realized heat recovery.Not only kept preferably with the compatibility of water but also avoided the corrosion of water side heat pipe well through the stainless steel and carbon steel of Passivation Treatment combination heat pipe; And a spot of incoagulable gas that produces also can be absorbed by the suction hydrogen agent at stainless steel tube top.The effect that the gas-liquid gravity heat pipe heat exchanger of the utility model has just reached with low cost like this, corrosion resistance good, heat pipe molten steel compatibility is good, can long-time running.
