The invention discloses a waste gas waste heat recovery device. The heat produced by the traditional oven can not be fully utilized, and can not be baked evenly, and the baking effect is poor. The suction pipe on both sides through the transition pipe is connected with the air cooled exchanger is arranged on the side of air cooled exchanger fan, oven heat pumping in the flue gas will be liquefied after cooling heat, collecting the heat released into the oven recycling. Air cooled exchanger side and the air supply pipe is connected to the other end of the air pipe on both sides along the wall of the box housing extends downward lower to the box is connected with the air inlet pipe, air inlet pipe along the length direction is installed in the lower part of the side wall on both sides of the room. The air inlet pipe is sealed at both ends, and the bottom of the air inlet pipe is provided with a plurality of air outlet holes, and the air exhauster is connected with the outside of the box house through the air pipe. As a result of adopting the design of the air condensing exchanger, the heat exchange is effectively carried out, and the heat utilization rate of the heat flue gas discharged from the oven is up to 90%, and the utilization rate of the waste gas heat is greatly improved.

一种废气余热回收装置
本专利技术涉及食品烘烤
,尤其是指一种废气余热回收装置。
技术介绍
食品烘烤房主要用于烤制加工鱼类,禽类,肉类食品,在休闲食品加工行业中,运用非常广泛。烤房一般采用封闭式结构,如输送线式烘烤箱,将烘烤食品放置在输送线上,经过烘烤箱烘烤,但是用于加热食品的热蒸汽往往只有70%伤亡热量得到利用,剩余的热量伴随着排出烤箱外的烟气而散失,造成巨大浪费,并且无法烘烤均匀,烘烤效果比较差。
技术实现思路
本专利技术的目的在于提供一种烘烤房用的结构简单、内部空间大、有效利用废气余温的废气余热回收装置。为实现上述目的,本专利技术所提供的技术方案为:一种废气余热回收装置,它包括有空气冷凝交换器、抽风机、吸风管、供风管;吸风管两侧通过过渡管与空气冷凝交换器一侧连接,空气冷凝交换器上设有抽风机,将抽进来的烤箱热烟气冷却液化后放热,收集释放的热量进入烤箱循环使用;空气冷凝交换器另一侧与供风管一端连接,供风管另一端沿箱房两侧壁向下延伸至箱房下部与进风管相连接,进风管沿长度方向安装在箱房两侧侧壁下部;进风管两端密封,其底部设有若干个出风孔,抽风机通过风管与箱房外部连接。所述进风管对称安装在箱房两侧壁下部。所述吸风管底部设有多个吸风口,其底部入口穿过隔板与箱房内腔连通。本专利技术由于采用空气冷凝交换器这一设计,有效地进行热量交换,烤箱排出的热烟气热量利用率达90%,大大提高了废气热量的利用率。本专利技术具有节约能量、操作方便、烘烤效果好的优点。附图说明图1为本专利技术的整体结构示意图。具体实施方式下面结合所有附图对本专利技术作进一步说明,本专利技术的较佳实施例为 ...
