中,都已经成为了不可缺少的重要组成分支,同时高压风机在烘干这个行业中,有两种不同的布置方式,且得到的使用效果和适用范围也因此是有一定区别的。 High pressure fan is the source of power equipment for conveying drying medium. In many drying equipment systems and air knife drying systems , it has become an indispensable important branch. At the same time, there are two different types of high pressure fans in the drying industry. Layout, and the use effect and scope of application are different.
In the drying system, for high-pressure fans, the more common arrangement is the use of a single fan and the combination of two blowers. For the first form, a single blower is placed after the dust recovery device, so that the drying equipment is in a negative pressure state.

The advantage of using this operation mode is that the dust and harmful gases in the drying system will not leak into the atmospheric environment, but due to the high negative pressure in the drying equipment, frequent starting and stopping of the high-pressure fan will cause the inside of the tower. Local instability, and external air may infiltrate into the lower dryer. Therefore, a single high-pressure blower method is more suitable for small drying systems.
For some large-scale drying equipment, two fans are needed, one as a blower and the other as an induced draft fan.
In this way, the entire system has greater flexibility. By adjusting the pressure distribution of the pipeline, the operating conditions of the dryer can be improved at the same time, so that it can be operated under a slight negative pressure close to atmospheric pressure.
When the high-pressure fan is applied to the drying equipment in this form, it not only takes into account the advantages of negative pressure operation, but also avoids air leakage into the system due to excessive negative pressure operation. Disadvantage. At the same time, the micro-negative pressure operation can ensure the highest recovery rate of the dust recovery device.
、运行能力以及操作条件等。 In the actual drying operation, which type of high-pressure fan is selected, many factors need to be considered, which specifically involve the type , operating capacity, and operating conditions of the high-pressure fan . Only high-pressure fans that meet actual requirements are our ultimate choice.
