Abstract
The utility model relates to a quasi-streamlined heat-transfer pipe type heat pipe air pre-heater, which is mainly applied to the industrial heating furnace, the rear part of the industrial boiler radiation chamber to high-effectively perform convective heat transfer and flue gas energy recovery without collecting dust. The heat pipe air pre-heater comprising a furnace wall (4), a quasi-streamlined section pipe (3), and an intermediate partition wall (8). The end part of the quasi-streamlined section pipe (3) is mounted and supported on the furnace wall (4) after being arranged in zigzag form. The middle part of the quasi-streamlined section pipe (3) is penetrated in the intermediate partition wall (8). The heat pipe air pre-heater has advantages that the cross section of the heat-transfer pipe is quasi-streamlined, when the high temperature flue gas transversely flows through the quasi-streamlined section pipe, the influence of Karman vortex street can be conquered to the most extent and the contact area between the flue gas and the heat-transfer pipe can be increased to the most extent to obviously improve the efficiency of flue gas convective heat transfer. The heat pipe air pre-heater improves the heat transfer efficiency, reduces the soot accumulation, saves the soot blowing steam, minimizes the convection section structure, reduces the steel consumption so as to further reduce the construction cost, save energy, and have high efficiency.
Description
Technical field
The utility model relates to the accurate streamlined heat transfer tubular type heat-pipe air preheater of heat-obtaining behind a kind of industrial heating furnace, the boiler radiation chamber.Be mainly used in industrial heating furnace, Industrial Boiler radiation chamber rear portion to efficient convection heat transfer' heat-transfer by convection, do not collect the flue gas heat-obtaining of dust.Belong to the field of energy-saving technology that industrial heating furnace and high efficiency boiler conduct heat.
Background technology
The heat-transfer pipe air preheater of heat-obtaining behind at present used industrial heating furnace, the boiler radiation chamber is to arrange by the snakelike shape of circular cross-section steel pipe to constitute circular cross-section heat-transfer pipe convection section module.Because when the circular cross-section convection tube conducts heat in the flue gas fluid, it is better in the face of spreading thermal effect that it meets air-flow, its back of the body air-flow face is because Kaman's eddy current street effect, then the flue gas at the back side can't contact by streamline with tube wall, not only heat-transfer effect is poor, and collection is grey easily, then influences more behind the collection ash and conducts heat, and forms vicious circle.Have to adopt certain grey means of blowing to blow ash like this, blow ash and will expend a large amount of steam, and disturbance the routine operating pressure of heating furnace, disturbed the overall performance of heating furnace.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of accurate streamlined heat transfer tubular type heat-pipe air preheater of carrying on the back the good and difficult collection ash of gas face heat-transfer effect is provided.
The purpose of this utility model is achieved in that a kind of accurate streamlined heat transfer tubular type heat-pipe air preheater, comprise furnace wall, accurate streamlined cross-section pipe and midfeather, described accurate streamlined cross-section pipe is its end installation of snakelike shape arrangement back and is supported in the furnace wall, and cross-under is in midfeather in the middle of the accurate streamlined cross-section pipe.
The utility model has the advantages that: accurate streamlined design is adopted in the heat-transfer pipe cross section, the high-temperature flue gas cross-current can overcome the influence in fluid Kaman eddy current street to greatest extent when accurate streamlined cross-section pipe, can increase the contact area of flue gas and heat-transfer pipe to greatest extent, significantly improve the smoke convection heat-transfer effect.Improve heat transfer efficiency, reduced heat-transfer pipe collection ash simultaneously, can save and blow grey steam and also can reduce the convection section structure, reduced the steel use amount, thereby reduced construction cost, not only energy-conservation but also efficient.

The specific embodiment
Referring to Fig. 1～2, the accurate streamlined heat-transfer pipe convection section module that the utility model relates to, support tube sheet by liner heatproof heat-barrier material constitutes furnace wall 4, accurate streamlined cross-section pipe 3 is its end installation of the horizontal back of snakelike shape and is supported in the furnace wall 4, middle cross-under is formed with certain included angle between accurate streamlined cross-section pipe 3 and the end furnace wall 4 in midfeather 8.Midfeather 8 is limited to the smoke convection section with flue gas and flows, with the medium in its heat transferred heat pipe, make the medium gasification, gas rises to the air flow side of midfeather opposite side, with the heat transferred cold air, the medium of gasification obtains cooling, be condensed into liquid, flow to the heat pipe bottom, conduct heat with smoke convection section flue gas again and gasify along thermotube wall, this process is carried out in circulation, can realize the function of air preheater.
Accurate streamlined cross-section pipe be snakelike shape horizontally its end appropriate size length of back do not carry out accurate fairing cross section and be processed into still rounded cross section, as Fig. 3～4, external elbow 6 of this circular cross-section part or circular cross-section are taken over 2 and are placed in the header box 7, elbow 6 and the circular cross-section that connects thereof are taken over 2 pipe sections has good mixed flow effect to tube fluid, plays the effect of augmentation of heat transfer; Accurate streamlined cross-section pipe is the horizontal back of snakelike shape, and it keeps original circular cross-section in midfeather 8 installation positions, as Fig. 3～4, forms two sections accurate fairing cross section structure.
It is streamlined that described accurate streamlined cross-section pipe promptly becomes along the cross section on the extratubal fluid flow direction.Accurate streamlined cross-section pipe can be the light pipe heat pipe, also can be reprocessed into finned tube, studded tube.
