Description
技术领域 technical field
本实用新型涉及能源回收利用领域,尤其是一种锅炉烟气余热回收利用系统。 The utility model relates to the field of energy recovery and utilization, in particular to a boiler flue gas waste heat recovery and utilization system.
背景技术 Background technique
以煤炭(木材)为燃料的锅炉在水产养殖行业的水产动物越冬过程中广泛使用,但大部分锅炉所产生的烟气都是直接排放,会排出大量的热能和灰尘,不仅浪费能源而且还污染环境。 Coal (wood)-fueled boilers are widely used in the aquaculture industry during the wintering of aquatic animals, but most of the flue gas produced by the boilers is directly discharged, which will discharge a large amount of heat and dust, which not only wastes energy but also pollutes environment.
近几年国内专利数据库公开了一些相关的锅炉专利技术: In recent years, domestic patent databases have disclosed some relevant boiler patent technologies:
例如【专利号】CN200720101036,【名称】双水套锅炉,【公告号】CN201041371Y,该实用新型提供了一种双水套锅炉,属于民用燃煤锅炉技术领域。所要解决的技术问题是提供一种热效率高,节省燃料的双水套锅炉。它包括双层壁构成的炉体、炉膛,双层壁间为水套,水套设有出水接口和回水接口,所说炉膛内设有内水套,内水套中部是烟箱,烟箱与炉膛间设有折反连通管,烟箱上端设有排烟管,内水套与水套间设有上连通管和下连通管。该锅炉将内水套置于炉膛内直接受炉火烘烤,升温快。内水套中部设烟箱,使炉气在炉内经过折反后再排出炉外,这样有利于热交换,可有效提高锅炉的热效率,节能效果明显。是民用燃煤锅炉的理想替代产品。但是,该实用新型结构复杂,燃烧所产生的烟气热量不能有效地利用,致使能量的流失,能源的浪费。 For example [patent number] CN200720101036, [name] double water jacket boiler, [notification number] CN201041371Y, this utility model provides a double water jacket boiler, which belongs to the technical field of civil coal-fired boilers. The technical problem to be solved is to provide a double-jacket boiler with high thermal efficiency and fuel saving. It includes a furnace body and a furnace composed of double-layer walls. There is a water jacket between the double-layer walls. The water jacket is provided with a water outlet port and a water return port. There is a reverse connecting pipe between the box and the furnace, a smoke exhaust pipe at the upper end of the smoke box, and an upper connecting pipe and a lower connecting pipe between the inner water jacket and the water jacket. The boiler puts the inner water jacket in the furnace and is directly baked by the fire, so the temperature rises quickly. A smoke box is set in the middle of the inner water jacket, so that the furnace gas is discharged out of the furnace after being deflected in the furnace, which is conducive to heat exchange, can effectively improve the thermal efficiency of the boiler, and has obvious energy-saving effects. It is an ideal substitute product for civil coal-fired boilers. However, the structure of the utility model is complicated, and the heat of flue gas generated by combustion cannot be effectively utilized, resulting in loss of energy and waste of energy.
例如【专利号】CN201320500198,【名称】一种热节能型热管余热回收锅炉系统,【公告号】CN203464310U,该实用新型公开了一种热节能型热管余热回收锅炉系统,包括锅炉、烟囱、以及从锅炉的出烟口到烟囱的主烟道,所述主烟道上设有热管换热器,所述热管换热器通过水管连接在锅炉上。该实用新型通过利用具有高导热性能的热管换热器代替老式锅炉省煤器,不仅提高了传热效率,而且具有结构紧凑、流体阻损小、有利于控制露点腐蚀等优点。但是,主烟道的热量没有充分利用,热量还是会从主烟道流失,不能有效地利用烟气的热量。 For example [patent number] CN201320500198, [name] a heat-saving heat pipe waste heat recovery boiler system, [notification number] CN203464310U, the utility model discloses a heat-saving heat pipe waste heat recovery boiler system, including boilers, chimneys, and The main flue from the smoke outlet of the boiler to the chimney is provided with a heat pipe heat exchanger on the main flue, and the heat pipe heat exchanger is connected to the boiler through a water pipe. The utility model replaces the old-fashioned boiler economizer with a heat pipe heat exchanger with high thermal conductivity, which not only improves the heat transfer efficiency, but also has the advantages of compact structure, small fluid resistance loss, and beneficial control of dew point corrosion. However, the heat of the main flue is not fully utilized, the heat will still be lost from the main flue, and the heat of the flue gas cannot be effectively utilized.
