The latest industry information
The types of rotary kiln can be divided into many kinds, but it is mainly used in chemical industry, building materials and other industries. Compared with other kilns, the use of this kiln is more, and the range of use is also wide. Since the utilization rate is high, then we need to know more equipment knowledge to prepare for unexpected needs. The more we know, the more convenient the operation is. Then, let's introduce the three core technologies of the kiln.
1. Energy saving. The heat storage and absorption rate of the kiln body, the equilibrium conduction of the working medium and the effective utilization of the heat source are all objective conditions affecting energy conservation. The design principle of the rotary kiln is based on the relevant baking system and the application principle of thermal equipment. The internal combustion billet is the carrier of the heat source. The increase of the size of the billet or the widening of the cross section is based on the baking principle of "high flame" and the drying through of the brick billet to promote "dry firewood" Fire "to achieve the energy-saving effect of internal combustion equipment. And from "hot and hot temperature" to "low temperature and long burning", burning bricks through is also energy saving. The high-yield equipment must be energy-saving, and the energy-saving equipment must be high-yield. The two characteristics are consistent and not contradictory.
2. Environmental protection. The bottleneck of the discharge of rotary kiln to meet the standard mainly depends on whether the oxygen content is more than 18%. At present, the so-called "three pinch oxygen source" is mainly adopted to control it. In the drying chamber, the moisture removal process of mixed gas is used to mix different simple gases for 7-12 seconds, so as to produce physical reaction between the components of the mixed gas, so as to change the gas characteristics of carbon dioxide, water vapor, nitrogen, carbon monoxide, oxygen and other gases in the flue gas, promote the change of various thermodynamic parameter values and thermodynamic differential relations of the working medium, and promote the change of internal energy, enthalpy and entropy of the gas, To control and mediate black, blue, white and smokeless. It is feasible to use the basic state parameters to change the physical and chemical composition of the exhaust gas to achieve the ideal emission of flue gas particles theoretically.
3. Digitization. Traditional equipment uses personal experience judgment from design to use, most of which are vague adjectives, so it is difficult to transmit accurate information. From design to use, the rotary kiln adopts quantifiable digital technology, which is easy to inherit and transform automation. The furnace is mainly embodied in the imitatability of operation, achieving the simple and popular purpose. Kiln is developed by thermal principle and other theories of industrial kiln, which breaks through the bottleneck of traditional kiln development.
This is the introduction of three core technologies of rotary kiln. To sum up, the main core technologies are nothing more than energy saving, environmental protection and digitalization, which we all want. The reason why the kiln has three core technologies is that it can develop to its present position and let users benefit from it. Then, in the future, we should also keep these three core technologies in mind to make it play better.
