It is natural that the gases produced in the production of the external heat rotary furnace should be discharged, but as the concept of environmental protection continues to deepen, we also know that the rest can not be discharged in any way, because it needs to be treated.
External heated using the circulation fan control system and the processing of waste gas, waste gas processing system circulation fan can improve the heat utilization rate of kiln and improve the uniformity of furnace temperature and furnace temperature, constant temperature period of circulation fan are placed, each cycle fan work alone each other, each temperature zone clapboard, make it a separate heating temperature zone, reduce the interference between each other, facilitate flexible adjustment, similar cooling period of air cooling fan, the circulation fan is controlled by multiple frequency converter for speed adjustment.
The front end of the furnace body is provided with a waste gas discharge pipe, and a insert board regulating valve is set in the pipe to regulate the waste gas flow. The waste gas moves in reverse with the heat treatment powder, and the waste heat is utilized to achieve the effect of energy saving. The whole set of equipment is composed of furnace body, transmission system and temperature control system, so in the whole production process, in order not to pollution treatment of the environment, it is not directly used in the inner furnace refractory fiber, refractory fiber high temperature crystallization powder to avoid the powder heat treatment products caused by pollution.
Waste gas processing depends on multiple systems to cooperate, if direct emissions after external heated rotary kiln production, it is against our surrounding environment condition, this is not just for the sake of others, the is for us to think of a better life in the future, in response to environmental protection, we can according to the paper explain the content, generally know about the emission how this kind of equipment.
If it is organic waste gas treatment: alkane, olefins, ketones, ethers, esters, aromatics, benzene and other hydrocarbon organic waste gas. Exhaust gas purification furnace can be used, its principle is to heat the organic waste gas to more than 760 degrees Celsius, so that the VOC in the waste gas in oxidation decomposition into carbon dioxide and water. High temperature gas produced by oxidation passes through the ceramic heat accumulator, which warms the ceramic and "accumulates heat". This "accumulates heat" is used to preheat subsequent organic waste gas. Thus, the heating consumption of exhaust gas heating is saved. Ceramic regenerator shall be divided into two (including two) or more, and each regenerator shall undergo heating, exothermic, cleaning and other procedures in turn to work continuously. After "exothermic" of the regenerator, proper amount of clean air should be introduced to clean the regenerator. The regenerator can only enter the "regenerator" procedure after the cleaning is completed. Otherwise, residual VOCs will be discharged to the chimney with the smoke and thus reduce the treatment efficiency.
