人们都知道热风炉适用在干燥物料领域并用途广泛,而其干燥的物料不允许被污染,尤其是干燥温度较低热敏性东西时,更是不可缺少的设备。例如:奶粉及制药、食品等领域。那间接式热风炉是如何工作的呢?
It is well known that hot blast stoves are widely used in the field of drying materials, and their dried materials are not allowed to be polluted, especially when the drying temperature is lower, they are indispensable equipment. 例如:奶粉及制药、食品等领域。 How does the indirect hot blast stove work?
什么是间接式热风炉
What is an indirect hot stove?
间接式热风炉其实也是加热装置,在操作过程中就是把蒸气及导热油和烟道气等做传热载体,并以多种形式进行热交换器从而加热空气,干燥物料。间接式热风炉^大的本质就是热量交换。热交换面积如果越大,那么承载的热转换率就高,节能效果就明显,炉体、换热器寿命就越长。在对热交换面积大小进行判断之时可从烟气温度辨别。烟温如果低,热转换效率就高,干燥物料时热交换面积就大。而燃料在和加热源分离的时候,也可用在人类取暖的方面。
In fact, indirect hot blast stove is also a heating device. In the process of operation, steam, heat conducting oil and flue gas are used as heat transfer carriers, and heat exchangers are used in various forms to heat air and dry materials. The essence of indirect hot blast stove is heat exchange. The larger the heat exchange area, the higher the heat transfer rate, the more obvious the energy saving effect, and the longer the life of the furnace body and heat exchanger. When judging the size of heat exchange area, it can be distinguished from the temperature of flue gas. If the smoke temperature is low, the heat transfer efficiency will be high, and the heat exchange area will be large when drying materials. Fuel can also be used in human heating when it is separated from the heating source.
工作原理
Working principle
热风炉如果就工作原理划分其可划分为蓄热式、换热式两种。蓄热式就是按其内部蓄热划分的,包括:分球式热风炉及格子砖热风炉两种,如果按燃烧方式划分就可以分为:顶燃式、内燃式及外燃式热风炉几种。在实际应用中提高风温是业内人士研究方向。^常用办法就是混烧燃料燃气,也关注增加炉内格子砖转换热面积,更可改变格子砖材质、密度等,如果改变蓄热体形状也可强化煤气热值及助燃空气在炉内预热。
Hot blast stove can be divided into regenerative type and heat exchange type according to its working principle. Regenerative type is divided according to its internal heat storage, including: spherical hot stove and lattice brick hot stove. If divided according to the combustion mode, it can be divided into top combustion type, internal combustion type and external combustion type hot stoves. Improving wind temperature in practical application is the research direction of professionals. ^ The commonly used method is to mix fuel and gas, and pay attention to increasing the heat transfer area of grid bricks in the furnace, which can also change the material and density of grid bricks. If the shape of regenerator is changed, the calorific value of gas and the preheating of combustion-supporting air in the furnace can also be enhanced.
总之,间接式热风炉在精加工领域应用范围很广,其有着自己干燥方式,是人们在干燥物料领域不可缺少的助手。
In short, the indirect hot blast stove has a wide range of applications in the field of finishing. It has its own drying method and is an indispensable assistant in the field of drying materials.
