本发明的实施方式Embodiments of the invention
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
请参阅图2和图3,本发明实施例提供的一种余热回收利用炒炉10,包括炉膛11、安装于炉膛11上的炒锅12、安装于炉膛11中的炉头13、用于向炉头13输送空气的送风机14和换热器15。所述炉膛11为封闭式炉膛11,以防止废气直接排出。换热器15第一介质通道154和第二介质通道153,其中,第一介质通道154连通送风机14与炉头13,从而使送风机14输送的空气经第一介质通道154进入炉头13;第二介质通道153与炉膛11相连通,用于排出炉膛11中的废气,从而使炉膛11中的废气进入第二介质通道153,以便与第一介质通道154进行热交换,从而对第一介质通道154中的空气进行加热。Referring to FIG. 2 and FIG. 3 , a waste heat recovery and utilization frying furnace 10 according to an embodiment of the present invention includes a furnace 11 , a wok 12 mounted on the furnace 11 , and a burner 13 installed in the furnace 11 for The burner 13 delivers an air blower 14 and a heat exchanger 15. The grate 11 is a closed grate 11 to prevent direct exhaust of the exhaust gas. The heat exchanger 15 is a first medium passage 154 and a second medium passage 153, wherein the first medium passage 154 communicates the blower 14 and the burner head 13, so that the air delivered by the blower 14 enters the burner head 13 through the first medium passage 154; The two medium passages 153 are in communication with the furnace 11 for exhausting the exhaust gas in the furnace 11, so that the exhaust gas in the furnace 11 enters the second medium passage 153 for heat exchange with the first medium passage 154, thereby contacting the first medium passage. The air in 154 is heated.
通过设置封闭式炉膛11,使得炉头13处燃烧产生的废气只能进入换热器15,防止余热浪费。使第一介质通道154连通送风机14与炉头13,使送风机14输送的空气经换热器15的第一介质通道154进入炉头13,如图2中空气沿箭头A流动;将第二介质通道153与炉膛11连通,使炉膛11中废气进入第二介质通道153,如图2中废气沿箭头B流动,从而与第一介质通道154进行换热,即对第一介质通道154中的空气进行加热,而这些空气再经炉头13燃烧后进入炉膛11,从而使废气带出的余热经第一介质通道154中的空气又送回炉膛11,热损失小,热利用效率高。By providing the closed hearth 11, the exhaust gas generated by the combustion at the burner 13 can only enter the heat exchanger 15 to prevent waste of waste heat. The first medium passage 154 is connected to the blower 14 and the burner head 13, so that the air delivered by the blower 14 enters the burner head 13 through the first medium passage 154 of the heat exchanger 15, as shown in Fig. 2, the air flows along the arrow A; The passage 153 communicates with the furnace 11 to allow the exhaust gas in the furnace 11 to enter the second medium passage 153, such as the exhaust gas flowing along the arrow B in FIG. 2, thereby exchanging heat with the first medium passage 154, that is, the air in the first medium passage 154. The heating is performed, and the air is burned by the burner 13 to enter the furnace 11, so that the residual heat from the exhaust gas is sent back to the furnace 11 through the air in the first medium passage 154, and the heat loss is small, and the heat utilization efficiency is high.
相应地,由于进入炉头13中的空气带有大量的热能,根据能量守恒定理,炉头13燃烧产生相同热量时,其需要消耗的燃烧也大幅降低,即可以减少燃料的用量,降低碳排放量和使用成本。而废气经热交换后再排出,降低了排烟温度,从而降低了对该余热回收利用炒炉10周围环境温度的影响。Correspondingly, since the air entering the burner head 13 has a large amount of heat energy, according to the conservation of energy, when the burner 13 is burned to generate the same heat, the combustion it needs to consume is also greatly reduced, that is, the amount of fuel can be reduced, and the carbon emission can be reduced. Quantity and cost of use. The exhaust gas is discharged after heat exchange, which reduces the exhaust gas temperature, thereby reducing the influence of the waste heat recovery on the ambient temperature around the fryer 10.
另外,由于是使用炉膛11废气对进气空气进行加热,其体积可以制作的相对较小,便于移动该余热回收利用炒炉10和降低成本。In addition, since the intake air is heated by using the exhaust gas of the furnace 11, the volume thereof can be made relatively small, and it is easy to move the waste heat to recycle the fryer 10 and reduce the cost.
进一步地,该余热回收利用炒炉10还包括用于引出第二介质通道153中废气的引风机16,引风机16与第二介质通道153相连。由于废气需要经过换热器15才能排出,通过设置引风机16,可以使换热器15的第二介质通道153中的废气能及时排出,进而将炉膛11中的废气排出,以利于空气进入炉膛11与燃料进行充分燃烧。另外,在炉头13燃烧前,开户送风机14与引风机16,还可以用来清理换热器15的第二介质通道153中的燃烧杂质,以使保证换热器15的通畅,提高换热器15的热交换效率。Further, the waste heat recovery fry furnace 10 further includes an induced draft fan 16 for extracting the exhaust gas in the second medium passage 153, and the induced draft fan 16 is connected to the second medium passage 153. Since the exhaust gas needs to pass through the heat exchanger 15 to be discharged, by providing the draft fan 16, the exhaust gas in the second medium passage 153 of the heat exchanger 15 can be discharged in time, and the exhaust gas in the furnace 11 can be discharged to facilitate the air entering the furnace. 11 and the fuel is fully burned. In addition, before the burner 13 is burned, the blower 14 and the draft fan 16 are opened, and the combustion impurities in the second medium passage 153 of the heat exchanger 15 can also be cleaned to ensure the smoothness of the heat exchanger 15 and improve heat exchange. The heat exchange efficiency of the device 15.
进一步地,炉膛11上开设有多个与第二介质通道153相连通的排烟口111,多个排烟口111分散设置于炉膛11的上部。由于炉头13处燃烧的火焰是向上升,对炒锅12进行加热,而随着废气的排出,大量的热会随废气移动,设置多个排烟口 111,并将多个排烟口111分散设置在炉膛11的上部,这样可以使废气分散从多个排烟口111进入换热器15,从而使废气中的热量可以分散开,以对炉锅均匀加热,使炉锅受热面积更广,加热更为均匀,提高热利用效率。Further, the furnace 11 is provided with a plurality of exhaust ports 111 communicating with the second medium passage 153, and the plurality of exhaust ports 111 are dispersedly disposed at an upper portion of the furnace 11. Since the flame burning at the burner 13 is rising upward, the wok 12 is heated, and as the exhaust gas is discharged, a large amount of heat moves with the exhaust gas, and a plurality of exhaust ports are provided. 111, and a plurality of exhaust vents 111 are dispersedly disposed in the upper portion of the furnace 11, so that the exhaust gas can be dispersed from the plurality of exhaust vents 111 into the heat exchanger 15, so that the heat in the exhaust gas can be dispersed to the furnace Uniform heating allows the furnace to have a wider heating area, more uniform heating, and improved heat utilization efficiency.
进一步地,炉膛11呈倒锥形台状,其上端开设有配合支撑炒锅12的开口,炉头13安装于炉膛11的底部。由于炉头13处燃烧火焰上升时,其范围也是逐渐扩大,而将炉膛11设为倒锥形台状,可以减小炉膛11的体积,减少热量的散发,提高热利用效率,还可以降低材料成本和该余热回收利用炒炉 10的体积和重量。当然在其它实施例中,炉膛11也可以设计为圆筒状等形状。炉膛11可以使用隔热板制作,以保证炉膛11内的温度,并且使炉膛11中的余热随废气进入换热器 15的第二介质通道153,以对第一介质通道154中的空气进行加热,提高热利用效率。当然也可以使用金属板制作。如使用隔热板或金属板制成倒锥形台壳体,在其上台面开设配合支撑炒锅12的开口,则炒锅12放置在该倒锥形台壳体上后,该倒锥形台壳体与炒锅12合围成封闭的炉膛11。当然在其它一些实施例中,也可以使用隔热板或金属板制成倒锥形台壳体,在其上台面上开设开口,在该开口中设置与炒锅12形状相配合的导热板,导热板封堵住该开口,从而使导热板及倒锥形台壳体合围成封闭的炉膛11。而该结构通过导热板将热量传至炒锅 12,可以使炒锅12的受热更为均匀。Further, the furnace 11 has an inverted conical shape, and an opening at the upper end thereof is provided to cooperate with the support of the wok 12, and the burner 13 is installed at the bottom of the furnace 11. Since the combustion flame rises at the burner head 13, the range thereof is gradually enlarged, and the furnace 11 is set as an inverted conical shape, which can reduce the volume of the furnace 11, reduce the heat emission, improve the heat utilization efficiency, and reduce the material. Cost and waste heat recovery 10 volume and weight. Of course, in other embodiments, the furnace 11 can also be designed in the shape of a cylinder or the like. The furnace 11 can be made using a heat shield to ensure the temperature inside the furnace 11 and to allow the residual heat in the furnace 11 to enter the heat exchanger with the exhaust gas. The second medium passage 153 of 15 heats the air in the first medium passage 154 to improve heat utilization efficiency. Of course, it can also be made of metal plates. If an inverted cone housing is formed by using a heat insulating plate or a metal plate, an opening for supporting the wok 12 is opened on the upper surface thereof, and the inverted pan is placed after the wok 12 is placed on the inverted conical housing. The table housing and the wok 12 are enclosed to form a closed hearth 11. Of course, in some other embodiments, the inverted cone housing may also be formed by using a heat insulating plate or a metal plate, and an opening is formed on the upper surface thereof, and a heat conducting plate matching the shape of the wok 12 is disposed in the opening. The heat conducting plate seals the opening so that the heat conducting plate and the inverted conical frustum case enclose the closed grate 11 . And the structure transfers heat to the wok through the heat conducting plate 12, the heating of the wok 12 can be more uniform.
