Product Name:  Honeycomb environmental protection and energy-saving drying furnace;
Equipment principle:
Honeycomb environmental protection "energy-saving drying furnace" is the essence of honeycomb high temperature burner mechanism, gas producer mechanism, low calorific value gas burner mechanism, chain grate coal feeding mechanism, and new curve combustion mechanism. It scientifically analyzes and simplifies five extremely complex equipment and combustion mechanism, and improves the furnace arch of the furnace to promote gas mixing in the furnace, organize radiation and flow of hot flue gas, so as to ensure timely ignition and combustion of fuel. Due to the application of a series of new ideas, methods, and materials in this furnace and their organic optimization combination, this equipment has truly become a new generation of environmentally friendly and energy-saving drying equipment that integrates various advantages of the collective.
The coal feeding system of this drying furnace adopts a chain grate structure, with a specially designed ultra-low speed reducer as the conveying power. The air supply system is a segmented air valve control structure, and a centrifugal fan customized according to the actual situation is used to supply air to the preheating ignition section, centralized combustion section, burnout section, and cooling section respectively. The chain grate motor is controlled by a frequency converter to ensure the stability, controllability, and energy saving of the equipment operation. The combustion system adopts a new type of curved combustion method in the lower part. In the case of incomplete combustion and partial production of coal gas, a honeycomb high-temperature combustion device is added. Under the rotation and stirring of sub high temperature wind, a second full combustion is achieved, thus achieving ideal combustion effect and satisfactory emission effect. The burnt slag is directly discharged into the slag pool.
The outstanding feature of this machine is its low power consumption, wide adjustable combustion temperature range, relatively clean high-temperature gas production, and wide industry use. Truly achieving the product goals of low one-time investment, low production costs, good corporate benefits, and better social benefits& nbsp;& nbsp;

1. In the production line of industrial (desulfurization/phosphorus) gypsum powder, most of the drum of the dryer is surrounded by a furnace made of refractory materials, and a heat storage device is added at an appropriate position on the drum to increase the heat transfer area, improve heat transfer efficiency, and achieve the goal of energy conservation and consumption reduction. The energy-saving drying furnace (which can save about 20% of coal and about 40% of energy) continuously heats the outside of the dryer (external drying can ensure that gypsum powder is not contaminated, to ensure a wider range of uses of gypsum powder). The energy-saving drying furnace uses frequency conversion technology to control the speed of the grate and applies honeycomb air distribution technology to ensure the coal burning effect obtained, thereby achieving the dual effect of energy saving and coal saving. After using this process simultaneously, the service life of the drying drum is extended by more than two years.
2. Applied in the drying process of cement stone mills, it can effectively reduce the comprehensive moisture content of the materials entering the mill. By utilizing strong ventilation inside the mill, during the drying and grinding process, the materials exchange with hot air inside the mill, allowing them to be quickly dried. The wind speed and air volume inside the mill have been further strengthened, and fine powder is quickly sent to the tail of the mill, truly changing the over grinding phenomenon of the mill. The material is dried and ground inside the mill, greatly improving the grinding efficiency, increasing the hourly output, and ensuring that the temperature at the tail of the mill is higher than the dew point, avoiding condensation on the dust collector bag.
3. Horizontal and vertical dryers have been widely recognized by users for their respective advantages and have a wide range of applications. However, the issue of heat sources has always been the main contradiction that troubles a large number of users. Whether it is direct coal combustion from the beginning, high-temperature boiling furnaces, or coal injection combustion furnaces, there are generally the following disadvantages in use: (1) high initial investment, (2) large configuration power, (3) high coal consumption, (4) generally low production, (5) complex installation, and (6) excessive maintenance costs in the later stage. After the application of environmentally friendly hot gas stoves in dryers, significant results have been achieved, overcoming the shortcomings of other equipment and making it an ideal replacement product.
4. Due to the large amount of water vapor generated during the dust collection process in the cement plant shaft kiln, if the temperature is too low, condensation will occur and cover the bag, causing the dust collector to not work. This furnace heats the humid air transported from the shaft kiln to the dust collector to above 60 ℃ to ensure that the dust removal bag does not condense and operates normally.
