Description
Affiliated technical field
The utility model relates to a kind of fuel oil, gas fired-boiler fume afterheat use device, is to make full use of the sensible heat of flue gas and the combined type heat pipe flue gas condensing energy-saving appliance of latent heat.
Background technology
Contain a large amount of protiums in fuel oil, the combustion gas, make fuel oil, gas fired-boiler contain a large amount of steam in discharging fume.The exhaust gas temperature of fuel oil, gas fired-boiler is higher, and generally more than 150 ℃, flue gas carries away a large amount of the physics sensible heat and the latent heat of vaporization.At present, the equipment of oil-burning gas-fired boiler UTILIZATION OF VESIDUAL HEAT IN mainly is the sensible heat that utilizes boiler smoke, does not make full use of for the latent heat of flue gas.Contain a large amount of steam in fuel oil, the gas fired-boiler flue gas, the latent heat of recycling the steam in the flue gas can effectively improve the efficient of boiler.Current, the Type of equipment that reclaims fume afterheat mainly is waterpipe type heat exchanger and fume tube type heat exchanger.Mainly there is following shortcoming in the waterpipe type heat exchanger: flue resistance increases significantly, influences the burner operation performance; Water flows in pipe, and flue gas flows outside pipe, for avoiding corrosion, needs resistant material more, and cost is higher; The heat exchanger entire arrangement has increased difficulty of construction and maintenance difficulty in flue.Mainly there is following shortcoming in the fume tube type heat exchanger: in order to overcome the corrosion of flue gas to the rear portion flue, all must arrange by-pass flue, partial fume is directly discharged with mix the back through cooled smoke by by-pass flue, reduce UTILIZATION OF VESIDUAL HEAT IN efficient; Flue gas discharges through behind the tube side, logical journey, and heat exchange efficiency is not high; The heat exchanger entire arrangement has increased difficulty of construction and maintenance difficulty in flue; The layout of by-pass flue has increased cost.No matter the waterpipe type heat exchanger still is the fume tube type heat exchanger, and heat transfer coefficient is little, and heat exchange area is big, causes equipment volume bigger, and the occupation of land space is bigger.
Heat pipe is one of the most effective heat transfer element, relies on the phase transformation of inside heat pipe hydraulic fluid to realize conducting heat.Heat pipe is studied and is originated from the U.S. the forties in last century, and be applied to space technology in the sixties, thereby attract the former Soviet Union, Britain, Italy, preceding West Germany etc. actively to be engaged in the research and development of hot pipe technique, the seventies, hot pipe technique developed rapidly, and hot pipe technique begins to play a role in civilian every field after the eighties.China begins the research of hot pipe technique the seventies, mainly lay particular emphasis on the application study of space technology and electronic devices and components cooling aspect, the later stage eighties, the research of hot pipe technique research beginning steerable energy utilization and power-saving technology aspect, in recent years, along with going deep into of hot pipe technique research and development, hot pipe technique has been widely used in every field such as the energy, chemical industry, traffic, electronics, building.Along with the raising of scientific and technological level and the variation of social demand, the field of hot pipe technique research and development will constantly be expanded.Whole heat pipe can be divided into three parts: evaporator section, adiabatic section and condensation segment.Working solution is vaporized into steam in the evaporator section heat absorption, under the effect of minute-pressure difference, steam enters condensation segment by the adiabatic section in the steam channel in tube chamber, in condensation segment, the steam release heat, the formation condensation water that condenses under the capillary force effect of imbibition core, is back to evaporator section by the imbibition core around the inner tubal wall.So periodic duty, heat pipe can and need not external force at the long-pending long-distance transmissions heat down of small bore very.
Summary of the invention
Utilize the shortcoming that the equipment heat transfer coefficient is little, heat transmission equipment is big in order to overcome existing fume afterheat, the utility model has designed a kind of combined type heat pipe flue gas condensing energy-saving appliance, this energy-saving equipment utilizes the principle of heat pipe, fully improve heat transfer coefficient, simultaneously can the combination evaporator case and cooling cylinder in heat exchange area, realize the optimization of heat exchange effect.
The technical scheme that its technical problem that solves the utility model adopts is: this energy-saving equipment comprises: evaporation tank, cooling cylinder, tube connector, condensate liquid are collected tapping equipment four parts, and its architectural feature is: evaporation tank is interior to be serpentine coil, manages to be finned tube; Material is copper, stainless steel, carbon steel; In the cooling cylinder is serpentine coil, manages to be that finned tube, material are copper, stainless steel, carbon steel; Tube connector couples together the finned tube in evaporation tank and the cooling cylinder, is divided into tedge and down-comer; Condensate liquid is collected tapping equipment and is arranged on the evaporation tank bottom, main condensate water of collecting in the discharging evaporation tank, and material is an ordinary carbon steel; The corresponding layout of serpentine coil in serpentine coil and the cooling cylinder in the evaporation tank, the tedge by correspondence is connected with down-comer, vacuumizes in the pipe, pours heat-pipe working medium, and formation is loop circuit heat pipe independently one by one.Its operating characteristic: flue gas enters in the evaporation tank, outside pipe, flows, and be heat-pipe working medium in the pipe; Cooling water or cooling air enter cooling cylinder, outside pipe, flow, and be heat-pipe working medium in the pipe; Flue gas enters evaporation tank the fin intraductal working medium is heated, flue-gas temperature reduces, steam in the flue gas formation condensate water of condensing, collect discharging by the condensate liquid gathering-device, heat-pipe working medium heat absorption evaporation forms steam in the evaporation tank internally finned tube, enters the cooling cylinder internally finned tube by tedge, by tube wall the heat transferred cooling water or the cooling air, cooling water heating or the cooling air heat, the steam heat release formation liquid refrigerant that condenses flows back to evaporation tank by down-comer in the pipe; Heated cooling water or cooling air can be used.Flue gas is existing sensible heat heat release in this equipment, and the latent heat heat release of steam is arranged again, has improved the fume afterheat utilization ratio.
The beneficial effects of the utility model are: boiler smoke enters the evaporation tank of this energy-conservation equipment, washes away in the evaporation tank one group of group coil pipe that crawls, and flue-gas temperature reduces, and sensible heat is reclaimed, and steam condenses in the flue gas simultaneously, and latent heat is reclaimed; Improved the boiler afterheat organic efficiency effectively; Because flue gas cigarette temperature reduces after entering evaporimeter gradually, front-seat coil pipe and rear portion coil pipe heat transfer efficiency change, can be by changing the uniformity that different heat pipe heat internal-filling liquid rates and vacuum realize different heat pipe heat heat exchange: because the boiler load difference, when the heat exchange amount changes, can be by increasing, subtract the optimization that heat pipe heat realizes heat exchange; Because the high efficiency of adopting heat pipes for heat transfer, under the situation that obtains same heat exchange amount, heat exchange area significantly reduces, make heat exchange energy-saving equipment volume reduce, simultaneously, because evaporation tank is arranged in the flue, arrange with the cooling cylinder split, help apparatus arrangement convenience in the boiler room.
