How to Solve the Pollution Caused in Drying Process
Drying machinery is specially researched, developed and designed to dry coal slime with the advantages of high water content, strong adhesion, high water binding capacity and low heating value. The particular design in simplified external layout of dryer not only increases the heating efficiency, but also avoids sticky and excessively dry phenomenon for coal smile in dryer.
In the wake of constant acceleration of China industrialization process, city, suburban district and rural township have become the gathering place for factories. Therefore, the various pollutions become the headache for people. For these problems, Henan Hongxing dryer experts have developed a new-type coal slime dryer with high efficiency, energy conservation and no pollution. Today, we will discuss about how to get rid of the pollution in coal slime drying process.
1. In the coal slime drying process, it is inevitable to form air pollution. Due to the extremely low moisture content in the later stage of coal slime drying process, some coal slime particles will be pumped out into atmosphere along with air dielectric. In addition, it is similarly unavoidable for coal burning phenomenon in the later stage on account of the extremely high drum temperature. Hence it is quite essential to install ash handling equipment and tail gas absorption device in the exhaust place of drying machine.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,combination crusher,stone crusher Welcome all of you to visit our official website.cement making machine:http://www.china-mills.com/p37.html
2. Coal slime contains various chemical substances, such as SS, CODcr, etc. In the process of heating and drying, there is a series of chemical reactions between chemical substance and water, which produces much toxic gas. For operating personnel, toxic gas can be very damaging to their health. Consequently, Hongxing new type coal slime dryer should be installed with filter plant to filter toxic gas for fear that toxic gas will pollute air.
