The top of the steam generator is provided with a residual heat utilization device. The space among the steam generator, the outer shell and the residual heat utilization device is a smoke passage. A vertical or horizontal fire pipe is used to exchange heat in the interior. The utility model realizes multi-time heating, and fully utilizes the energy source. The outlet temperature is below 160 DEG C. The heat efficiency of the coal firing is higher than 60 percents. The heat efficiency of the oil firing is higher than 85 percents. The utility model has the advantages of simple structure, compact structure, easy fabrication, light weight, low energy consumption, less investment, and high safety. The utility model can be used for low-pressure boilers or atmospheric hot water boilers, and can be especially used for boilers of miniature or small type.
Description
The utility model relates to a kind of fire-tube type heat exchanger, can be widely used in boiler, water heater industry.
In the prior art, the general mode of heat pipe that adopts is carried out exchange heat, as Chinese patent ZL94244591.0 number " efficient, quick, multifunction water-heating stove " disclosed water heater, in order to strengthen the free convection speed of heating surface area and raising water, heat pipe reaches the 20-50 root, produces problems such as complex structure, cost height, manufacture difficulty be big thus; Thermal current directly rises from the chimney discharge in addition, causes the exhaust gas temperature height, and the thermal efficiency is low.Chinese patent ZL91212203.X number " the efficient water heater of fire-tube type " disclosed water heater, though avoid direct smoke evacuation as far as possible, the improvement dynamics is little, still belongs to direct fume exhausting type, and structure is not compact, the maintenance cost height.
The purpose of this utility model is for overcoming the deficiency of above-mentioned prior art, provide a kind of simple in structure, compact, and energy consumption is low, thermal efficiency height, the low pressure that production cost is low or normal pressure heat exchanger.
The utility model comprises the blow-off pipe that communicates with the steam generator bottom, be installed in the fire tube in the steam generator, be positioned at the combustion chamber of steam generator bottom, steam generator escape pipe and pressure gauge connection, and the cold water preheating device is the UTILIZATION OF VESIDUAL HEAT IN device, the filler, water-level measuring post etc., its fire tube one end is communicated with the combustion chamber, the other end is communicated with flue and chimney, it is characterized in that steam generator is held in the shell, interval between shell and steam generation wall constitutes the lower flue that is connected with fire tube, adopt vertical or horizontal fire tube, vertical fire tube is U type or M type or ripple type, and horizontal fire tube is snake dish-type or ripple type.Steam generator is one the airtight container of water-level measuring post to be housed down, a bottom is installed on it upwards caves in, be equipped with UTILIZATION OF VESIDUAL HEAT IN device water-level measuring post, sealing.The space that UTILIZATION OF VESIDUAL HEAT IN device bottom upwards is recessed to form constitutes the upper flue that communicates with lower flue, and the upper smoke tube that passes the UTILIZATION OF VESIDUAL HEAT IN device is connected with upper flue down, goes up to communicate with chimney.On the UTILIZATION OF VESIDUAL HEAT IN device filler is arranged, and have between pipeline and the steam generator and be connected.Fire tube in the steam generator is as adopting then two one group of cross-shaped arranging of vertical fire tube, and quantity is decided as required, and horizontal fire tube then is levels and arranges.
Because steam generator of the present utility model is arranged in shell, can carry out four heat utilizations, flue gas is tortuous to rise, and makes full use of the energy, and outlet temperature is lower than 160 ℃, burns the coal thermal efficiency and is higher than 60%, and the oil firing thermal efficiency is higher than 85%.It is simple in structure, compact, makes easily; In light weight, energy consumption is low, small investment, and high efficiency, safe in utilization, can be applicable to low-pressure boiler or atmospheric hot-water boiler, particularly miniature or ting model is serial.
Accompanying drawing is the complete section schematic diagram that the utility model adopts vertical U type fire tube.
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, blow-off pipe 1 is equipped with in the steam generator bottom, combustion chamber 15 is positioned at the steam generator bottom, an end that is installed in the fire tube 4 in the steam generator communicates with the combustion chamber, 14 of the other end and shell 2 and steam generation walls the interval---lower flue 3 is connected, the escape pipe 7 and the pressure gauge connection 9 that water-level measuring post 13 are housed down on the steam generator and from upper smoke tube 11, pass.UTILIZATION OF VESIDUAL HEAT IN device 6 places on the steam generator, is the body of falling the matrix of a sealing, chimney 8, filler 10 is arranged on it, go up water-level measuring post 12, links to each other with pipeline is arranged between steam generator.The space that UTILIZATION OF VESIDUAL HEAT IN device bottom upwards is recessed to form constitutes down the upper flue 5 that communicates with lower flue, upward communicates with upper smoke tube.
During use, the firepower in the combustion chamber is the base plate of heating steam generator at first; Red-hot flue gas carries out heat exchange with water once more by the fire tube that is fully immersed in the water; The flue gas that overflows in the fire tube carries out integral heat insulation and heating to steam generator again during by lower flue; When flue gas flow through upper flue and upper smoke tube, waste heat wherein was used to heat the UTILIZATION OF VESIDUAL HEAT IN device the 4th time---and boiling water is provided and is the additional water of steam generator.Front and back are carried out four heat utilizations altogether, so outlet temperature is controlled at below 160 ℃.The utility model adopts the negative pressure exhausting, and pressing force or temperature are controlled automatically, but also malleation air blast in case of necessity; Because the fire tube complete immersion heats in water, can improve working conditions preferably, anti-fire-stopping pipe damages.
