Description

一种霄家用取暖炉及使用方法A kind of Xiao household heating stove and using method 【技术领域】【Technical field】
本发明属于生物质燃料燃烧技术领域,具体涉及一种霄家用取暖炉及使用方法。The invention belongs to the technical field of biomass fuel combustion, and in particular relates to a domestic heating stove and a use method.
【背景技术】【Background technique】
生物质被认为是一种被忽略的能源,具有遍在性、丰富性、可再生性等特点。生物质能的高效开发利用,对解决能源、生态环境问题将起到十分积极的作用。目前应用较多的生物质成型燃料虽然具有成本低,加工方便等特点,但与生物质微米燃料相比较,其燃烧不够充分,燃烧温度不高,易产生大量烟气等缺点,而生物质微米燃料粒径较小,与空气接触更加充分,使得其燃烧速度与效率大大提高,进而能够获得更高的燃烧温度,因此生物质微米燃料的应用前景更加广阔。华中科技大学肖波教授及其团队将生物质高效生产的粒径小于250微米的“微米燃料”,称之为霄燃料,霄燃料能够实现1400℃以上高温的燃烧,具有广阔的市场前景。Biomass is considered to be a neglected energy source, which has the characteristics of ubiquity, abundance, and renewability. The efficient development and utilization of biomass energy will play a very positive role in solving energy and ecological environment problems. Biomass briquette fuel, which is widely used at present, has the characteristics of low cost and convenient processing, but compared with biomass micron fuel, its combustion is not sufficient, the combustion temperature is not high, and it is easy to generate a large amount of flue gas. The fuel particle size is smaller and the contact with the air is more sufficient, which greatly improves the combustion speed and efficiency, and thus can obtain a higher combustion temperature. Therefore, the application prospect of biomass micron fuel is broader. Professor Xiao Bo of Huazhong University of Science and Technology and his team called the "micron fuel" with a particle size of less than 250 microns efficiently produced by biomass.
目前国内基本上只有北方提供集中供暖,而中部及中部偏南地区由于低温期较短,采用集中供暖成本较高,效益不佳,但随着人民生活水平的逐渐提高,取暖需求日渐高涨。但若全部采用空调制热取暖,会大幅增加居民用电量,使得供电压力骤增,同时农村地区供电设施不够完善,容易导致用电风险大幅提高。同时农村地区的秸秆、稻杆等原生的大量生物质燃料为霄家用取暖炉提供了天然的地利与优势,也减少了废弃生物质的处理需求与成本。At present, only the north provides central heating in China. However, due to the short low temperature period in the central and southern regions, the cost of central heating is high and the benefits are not good. However, with the gradual improvement of people's living standards, the demand for heating is increasing day by day. However, if all use air conditioners for heating and heating, it will greatly increase the electricity consumption of residents, causing the power supply pressure to increase sharply. At the same time, a large number of native biomass fuels such as straw and rice straw in rural areas provide natural geographical advantages and advantages for Xiao household heating stoves, and also reduce the demand and cost of waste biomass treatment.
CN105570874B公开了一体式生物质自力旋风气化燃烧炉,该技术方案从外壳到燃烧室内筒、外筒形成一烟窗结构,使气化室外的热空气产生很强的上拔力,进行强力增氧;导流叶片沿着气化室口向右切向,产生顺地 偏力方向的逆时针方向的强力气旋,充分混合燃气,使生物质燃烧充分。然而该技术方案不能够将生物质燃烧能充分利用,还存在改进的空间。CN105570874B discloses an integrated biomass self-powered cyclone gasification combustion furnace. The technical scheme forms a smoke window structure from the outer casing to the combustion inner cylinder and the outer cylinder, so that the hot air outside the gasification room can generate a strong upward pulling force to increase the strength. Oxygen; the guide vane is tangential to the right along the mouth of the gasification chamber, generating a strong cyclone in the counterclockwise direction along the direction of the ground bias, fully mixing the fuel gas, and making the biomass burn fully. However, this technical solution cannot fully utilize biomass combustion energy, and there is still room for improvement.

(1)本发明霄燃料相比于生物质成型燃料,具有燃烧更加彻底且更快速,燃烧温度高,能量释放速度更快更集中,产生的废弃物(如炉渣等)更少等优点,节约了重要资源,并提高了原本为废弃物的生物质资源的利用效率,符合国家环保政策,燃烧炉炉膛内旋风进料,增加了燃料在炉膛内的燃烧时间,提高燃烧效率和热量利用率,由于燃烧更加彻底,故大幅减少了灰烬的产生量,设置主、次换热水箱,主换热水箱包围燃烧炉,将燃烧炉炉体产生的热量辐射也利用起来,使得燃烧产生的热量能够被更加充分的利用,提高了能量利用率。(1) Compared with biomass briquette fuel, the present invention has the advantages of more thorough and faster combustion, higher combustion temperature, faster and more concentrated energy release, less waste (such as slag, etc.) important resources, and improve the utilization efficiency of biomass resources that were originally waste, in line with national environmental protection policies, cyclone feeding in the furnace hearth, increase the burning time of fuel in the hearth, improve combustion efficiency and heat utilization, Since the combustion is more thorough, the amount of ash produced is greatly reduced. The main and secondary hot water exchange tanks are installed. The main hot water exchange tank surrounds the combustion furnace, and the heat radiation generated by the combustion furnace body is also utilized, so that the heat generated by combustion can be used. More fully utilized, improved energy utilization.
(2)本发明将炉膛设计为三层,进料管轴线与炉膛圆周相切,这样燃料在炉膛内依次螺旋上升、螺旋下降和螺旋上升,在相同炉膛容积条件下,大幅增加了燃料在炉膛内的时间,给燃料气化、完全燃烧提供了充足的时间。由于燃烧十分彻底,大量减少了烟气中灰尘的含量,既能够高效利用燃料又能够减少烟尘排放,保护环境。(2) The present invention designs the furnace into three layers, and the axis of the feed pipe is tangent to the circumference of the furnace, so that the fuel spirally rises, spirals down and spirals up in the furnace successively. enough time for fuel gasification and complete combustion. Since the combustion is very thorough, the dust content in the flue gas is greatly reduced, which can not only utilize the fuel efficiently, but also reduce the soot emission and protect the environment.
(3)本发明搅动机构能够破坏微米燃料在进料过程中产生的堆积结构, 保证下料的连续性,搅动机构分别设置在料斗中部以保证其能够接触到大部分燃料。另外在进料口上方设置定量给料机构,也就是定量给料绞龙,定量给料机构(4)设置有调速器,以实现定量给料功能,改变实时的进料量以保证良好的燃烧效果。(3) The stirring mechanism of the present invention can destroy the accumulation structure of the micron fuel in the feeding process and ensure the continuity of feeding. In addition, a quantitative feeding mechanism, that is, a quantitative feeding auger, is set above the feeding port. The quantitative feeding mechanism (4) is provided with a governor to realize the quantitative feeding function and change the real-time feeding amount to ensure a good Burning effect.
(4)本发明在进料口之后加装鼓风机,将霄燃料以较高的速度吹入炉膛,这样一方面可以利用风机侧高速气流产生的空气负压促进料仓进料,另一方面将霄燃料高速吹进炉膛可以使霄燃料与空气充分混合保证燃烧完全,还防止了霄燃料及燃烧后残留灰分在炉膛内堆积,影响燃烧过程,烧坏炉体。(4) The present invention is equipped with a blower after the feeding port, and the fuel is blown into the furnace at a higher speed, so that on the one hand, the negative air pressure generated by the high-speed airflow on the side of the fan can be used to promote the feeding of the silo, and on the other hand, the The high-speed blowing of the fuel into the furnace can fully mix the fuel and the air to ensure complete combustion, and also prevent the fuel and residual ash from accumulating in the furnace, affecting the combustion process and burning out the furnace body.
(5)本发明燃烧炉采用热电偶通电加热或燃气加热点火方式,避免了每次使用需要明火引燃的操作,方便快捷。主换热器与炉膛出火口连接处设计为收口形式,使火焰喷出时更加集中,减少热量损失,并防止灰分在两者连接处逸散,杜绝了随着使用时间的延长,灰尘在装置内部逐渐堆积,造成装置堵塞,清理困难、与炉体烧结甚至引发火灾的风险。二次换热水箱可以阻拦火焰,防止明火外露,提高了安全系数。霄燃料燃烧产生的烟尘伴随火焰喷出后,通过二次换热水箱后侧的出尘孔,被除尘系统的引风机吸入布袋除尘器中,保证取暖炉适用于室内空间,更加环保,且便于清洁。(5) The combustion furnace of the present invention adopts the electric heating or gas heating and ignition mode of the thermocouple, which avoids the operation that needs to be ignited by an open flame every time it is used, and is convenient and quick. The connection between the main heat exchanger and the fire outlet of the furnace is designed to be closed, which makes the flame more concentrated when spraying, reduces heat loss, and prevents ash from escaping at the connection between the two. The inside gradually accumulates, causing blockage of the device, difficulty in cleaning, sintering with the furnace body, and even a risk of fire. The secondary hot water exchange tank can block the flame, prevent the open flame from being exposed, and improve the safety factor. After the smoke and dust generated by the combustion of Xiao fuel are ejected with the flame, it is sucked into the bag filter by the induced draft fan of the dust removal system through the dust outlet on the back side of the secondary hot water tank, ensuring that the heating furnace is suitable for indoor space, which is more environmentally friendly and convenient. clean.
