Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1 and Figure 2, the gas type preheating type heat exchanger of the present embodiment, comprises thermal cycle room 1, becomes baking chamber 2 and heat passage in thermal cycle room 1 by baffle for separating, places and cure chassis 3 in baking chamber 2; Dividing plate comprises lateral partitions 4 and the first vertical baffle 5, second vertical baffle 6 of being connected to below lateral partitions 4 and the 3rd vertical baffle 7, formed on baking chamber 2, second vertical baffle 6 and the 3rd vertical baffle 7 with air-flow pilot hole 8 between lateral partitions 4, second vertical baffle 6 and the 3rd vertical baffle 7; Arrange " hair fastener " type heat-exchange tube 10, first vertical baffle 5 be provided with between the sidewall of the second vertical baffle 6 and thermal cycle room 1 is placed between the interior comb 101 of heat-exchange tube 10 and outer comb 102 more; The interior comb 101 of heat-exchange tube 10 is communicated with the lower end of outer comb 102, and the upper end of outer comb 102 is connected with combustor assembly 12, and combustor assembly 12 is installed on the top of thermal cycle room 1; The top of thermal cycle room 1 is also provided with wind wheel 13 and is separated into top honeycomb duct 15 by top board 14, and wind wheel 13 is placed in above the opening 151 of top honeycomb duct 15.
Further, be provided with steam generator 9 between the first vertical baffle 5 and the second vertical baffle 6, steam generator 9 is positioned at the import department of the air-flow pilot hole 8 of the second vertical baffle.
Further, the upper end of interior comb 101 is connected with gas sampling box 11, and gas sampling box 11 is installed on the top of thermal cycle room 1.
Further, the lower end phase company headquarters 103 of interior comb 101 and outer comb 102 is with from up-narrow and down-wide transition structure.
When the utility model uses, product 17 is placed on baking tray 16, and baking tray 16 is positioned over and cures on chassis 3, cures chassis 3 and is placed in baking chamber 2; In bake process, air-flow is extracted out by wind wheel 13 and is then heated after heat-exchange tube 10 from baking chamber 2, and then is forcibly fed in baking chamber 2, forms circulation.
When air-flow is through heat-exchange tube 10, air-flow is parallel with the axis of heat-exchange tube 10, and it is contrary that flow direction flows to thermal current in heat-exchange tube 10, heat-exchange tube 10 passage and gas channel once vertically can cross or repeatedly vertically to cross, but in the flow direction of air-flow and heat-exchange tube 10, thermal air current is to being rightabout all the time.The benefit of such design is that counterflow configuration is beneficial to than cross-flow structure and obtains better energy consumption utilization ratio.
In the utility model, the lower end i.e. interior comb 101 of heat-exchange tube 10 is bent to " hair fastener " shape with the connecting portion of outer comb 102 lower end, and interior comb 101 is in same plane with outer comb 102.Between many heat extractions exchanging tube 10, adjacent spacing is 6 inches, and its compact conformation takes up room little, thus reduces costs and reduce the appearance and size of baking oven.The air-flow of circulation is arranged to flow out from baking chamber 2 near top, flow downward along interior comb 101 is parallel, then head is turned upwards through lower end air-flow, along the axial flow of outer comb 102, then air-flow is under the effect of wind wheel 13, get back in baking chamber 2 through top flow-guiding channel 15, so formed and circulate.The utility model provides one can allow air-flow and the long path fully contacted by the heat-exchange tube heated, and absorbs maximum heat from heat-exchange tube, and its heat utilization rate is high.
In the utility model, at air-flow pilot hole 8 place of flowing out baking chamber 2 near air-flow, steam generator 9 is set, heat is absorbed in the air-flow flowed out from here, steam is produced after accumulation of heat, can effectively allow gas flow temperature herein lower than the temperature of air-flow when being got back to baking chamber by heating, such circulating current that can make enters heat exchanger with minimum temperature and is heated, and effectiveness of heat exchanger is maximized.
The gas sampling box 11 arranged in the utility model, is used for collecting the hot gas of discharging from heat-exchange tube 10.Preheating is carried out for the air needed for combustion-supporting heat exchanger combustion with the heat of waste gas in gas sampling box 11.This pre-burning heat transfer can make up the heat loss in combustion process, significantly reduces energy resource consumption.
The utility model is applicable to following baking oven: 1, gas type hot air type Rotating oven: bread and baking tray are placed on chassis, and chassis can free in and out, and time roasted, chassis rotates in baking oven; 2, gas type hot-air roaster: without chassis, bread and baking tray are placed on bracket; 3, the mini baking oven of gas type: bread and baking tray are placed on chassis, but chassis can not be come in and gone out, and time roasted, chassis rotates in baking oven.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changed or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
