Description
Technical field
The utility model relates to a kind of boiler condenser heat exchange element, is specifically related to a kind of helical fin heat pipe.
Background technology
Along with oil-burning gas-fired boiler is greatly developed, in order to improve the efficiency of boiler, smog discharge temperature is more and more lower.Now current conventional boiler exhaust gas temperature is generally at about 165 DEG C, the efficiency improving boiler just requires that boiler has lower exhaust gas temperature, but exhaust gas temperature reduces the consequence brought, moisture content in boiler smoke will condense out, concerning traditional carbon steel boiler plant heating surface, the condensed water in flue gas is deathblow to service life of equipment.One reasons is easy to produce rust corrosion for: the Q2 in the excess air that in flue gas, condensed water and flue gas comprise mixes, and reduces heat exchange efficiency; Reason is on the other hand: the RQ2 generation acidic liquid in flue gas in condensed water solution absorption flue gas is bonded on heat transmission equipment and corrodes equipment, and the heat transmission equipment life-span is had a greatly reduced quality.As long as leaking appears in the heat transmission equipment of boiler, boiler just must overhaul in blowing out, and severe patient needs heat exchanging equipment type integral replacing.If adopt stainless steel to replace carbon steel material, although can improve the life-span of heat transmission equipment, it is very large to invest excessive and boiler overall structure, and cost of investment can increase considerably.
Utility model content
The utility model is intended to provide that a kind of cost is lower, the helical fin heat pipe of long service life.
Helical fin heat pipe in this programme, comprise the heat pipe vertically arranged, heat pipe bottom is evaporator section, and top is cooling section; Described heat pipe is made up of shell, liquid-sucking core and end cap, and the two ends of shell seal and are negative pressure state by described end cap; The outer wall of described evaporator section is fixedly connected with fin, is provided with adiabatic section between evaporator section and cooling section; Described liquid-sucking core is capillary-porous material and is overlying on the inwall of shell, is perfused with core liquid in shell, and this core liquid level is in evaporator section.
The utility model has the advantages that: (1) due to the exothermic coefficient of water and shell large, so cooling section adopts light pipe, namely save material, again reduce processing cost; (2) because evaporator section outer wall is fixedly connected with fin, when flue gas passes through, fast heat can be passed to core liquid by fin and make core liquid heat absorption evaporation; (3) due to the inwall of shell being covered with liquid-sucking core, cooled core liquid steam can be absorbed fast, accelerate the circulation of core liquid; (4) because heat pipe is unit heat exchange structure, even if a certain fin heat pipe is by flue gas corrosion, leak, the entirety that can't affect heat transmission equipment uses, and improves the service life of equipment.
Further, the liquid level of described core liquid is not higher than the fin height of evaporator section.Cold side, boiler feedwater process and heat pipe condensation side are carried out heat exchange and boiler feed temperature are improved, and the high-temperature cooling water that boiler feedwater is discharged from delivery port directly enters boiler, by heat recovery and utilization.
Further, described fin is helical form.Use many helix tubes to carry, improve heat exchange efficiency.
Further, the boiling point of described core liquid is lower than 80 degree.Easy vaporization, low-temperature heat exchange is effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model helical fin heat pipe embodiment;
Schematic diagram when Fig. 2 is the use of the utility model helical fin heat pipe embodiment.
In figure, 1 is shell, and 2 is liquid-sucking core, and 3 is steam flow, and 4 is core liquid, and 5 is fin, and 7 is dividing plate, and 9 is fixed head.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
According to Fig. 1, a kind of helical fin heat pipe, comprise the heat pipe vertically arranged, heat pipe is made up of shell 1, liquid-sucking core 2 and end cap, and the two ends of shell 1 seal and are negative pressure state by described end cap.This heat pipe top is cooling section, and bottom is evaporator section.Cooling section is light-pipe structure; The outer wall of evaporator section is welded with spiral helicine fin 5.Shell 1 is perfused with core liquid 4, and the liquid level of core liquid 4 is lower than the height of fin 5.The inwall of shell 1 is coated with liquid-sucking core 2, this liquid-sucking core 2 is capillary-porous material, absorbs after being convenient to the steam cooling to core liquid 4.Adiabatic section is provided with, this adiabatic section and dividing plate 7 clamping between evaporator section and cooling section.The lower end of evaporator section and fixed head 9 clamping.
During work, multiple helical fin 5 heat pipe composition helical fin 5 heat pipe heat, boiler smoke flows between dividing plate 7 and fixed head 9, when the boiler smoke of high temperature by evaporator section time, because core liquid 4 boiling point is low, the heat conducted by fin 5 makes core liquid 4 rapid evaporation absorb heat.When core liquid 4 steam rises to cooling section, because cooling water flows through from dividing plate 7, cooling water carries out quick exchange heat by the light pipe of cooling section and core liquid 4 steam, and core liquid 4 steam is cooled, flow to evaporator section by Action of Gravity Field and realize a closed circuit, so carry out heat exchange repeatedly.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
