QG系列气流干燥机

QG series Air Stream Dryer

1, QG series Air Stream Dryer - working principle

By introducing wet materials and heated natural air into the dryer at the same time, the two are fully mixed. This mixing process greatly increases the area of heat and mass exchange, resulting in rapid evaporation and drying of the material in a very short time (usually only 0.5 to 2 seconds). After drying, the finished material is discharged from the cyclone separator, and a small amount of flying powder is recycled through the cyclone dust collector or bag dust collector.

According to the different mode of operation, the Air Stream Dryer can be divided into two types of negative pressure operation and positive pressure operation. For example, type Q is a negative pressure operation, and the material does not directly pass through the fan; QG type is positive pressure operation, the material needs to pass through the fan, and has a certain crushing effect in the process. The FG model uses exhaust gas recycling technology, while the JG model is an enhanced Air Stream Dryer that integrates the advantages of flash drying and air drying, and is an innovative drying equipment designed for specific user needs.

一、QG系列气流干燥机--工作原理

气流干燥机通过将湿物料与加热后的自然空气同时引入干燥机内部，实现两者的充分混合。这种混合过程极大地增加了热质交换的面积，从而在极短的时间内（通常仅0.5至2秒）实现物料的快速蒸发干燥。干燥完成后，成品物料从旋风分离机排出，而少量飞粉则通过旋风除尘机或布袋除尘机回收再利用。

根据操作方式的不同，气流干燥机可分为负压操作和正压操作两种类型。例如，Q型为负压操作，物料不直接经过风机；QG型为正压操作，物料需通过风机，并在此过程中产生一定的粉碎作用。FG型则采用尾气循环技术，而JG型则是一种强化型气流干燥机，集成了闪蒸干燥与气流干燥的优点，是专为特定用户需求设计的创新干燥设备。

2, QG series Air Stream Dryer - equipment characteristics

2.1. High drying strength and low equipment investment: Air Stream Dryer is famous for its extremely high processing capacity and small equipment volume, and has a wide range of evaporation water capacity (50kg/ H-1500kg /h), which effectively reduces the equipment investment cost and has significant advantages compared with other drying equipment.

2.2. High degree of automation, good product quality: the whole drying process is carried out in closed pipes, and the drying time is very short, which is easy to realize automatic control. Because the product is isolated from the outside environment, the risk of pollution is reduced and the quality of the product is guaranteed.

2.3. Complete equipment supply, flexible heat source selection: air drying equipment is usually supplied in complete sets, and users can choose basic configuration or additional auxiliary equipment such as dust removal machine according to actual needs. At the same time, the selection of various heat sources, including steam, electricity, hot blast stove, etc., according to the heat resistance temperature of the material and local conditions flexible configuration, improve the applicability and economy of the equipment.

二、QG系列气流干燥机--设备特点

1. 干燥强度大，设备投资省：气流干燥机以其极高的处理量和较小的设备容积著称，蒸发水份能力范围广泛（50kg/h－1500kg/h），有效降低了设备投资成本，相较于其他干燥设备具有显著优势。

2. 自动化程度高，产品质量好：整个干燥过程在密闭管道内进行，干燥时间极短，便于实现自动化控制。由于产品与外界环境隔绝，减少了污染风险，保证了产品的优质性。

3. 设备成套供应，热源选择灵活：气流干燥设备通常成套供应，用户可根据实际需求选择基本配置或增配除尘机等辅助设备。同时，热源选择多样，包括蒸汽、电、热风炉等，根据物料耐热温度和当地条件灵活配置，提高了设备的适用性和经济性。

According to different application scenarios and functional requirements, Air Stream Dryer can be divided into four series:

1. Q series basic type: suitable for rapid drying of general materials, with simple structure and convenient operation.

2. QG series fan and dispersion model: Through the combination of fan and dispersion machine, enhance the dispersion and drying effect of materials, suitable for occasions with high drying effect requirements.

3. FG series tail gas cycle type: The use of tail gas cycle technology, improve thermal efficiency, reduce energy consumption, suitable for large-scale production or need high efficiency and energy saving occasions.

4. JG enhanced type: integrates the advantages of flash drying and air drying, with stronger drying capacity and a wider range of application, suitable for special materials with high drying speed and quality requirements.

气流干燥机根据不同应用场景和功能需求，可分为四大系列：

1. Q系列基本型：适用于一般物料的快速干燥，具有结构简单、操作便捷的特点。

2. QG系列风机兼分散机型：通过风机和分散机的结合，增强了对物料的分散和干燥效果，适用于对干燥效果要求较高的场合。

3. FG系列尾气循环型：采用尾气循环技术，提高了热效率，降低了能耗，适用于大规模生产或需要高效节能的场合。

4. JG强化型：集成了闪蒸干燥与气流干燥的优点，具有更强的干燥能力和更广泛的适用范围，适用于对干燥速度和质量要求极高的特殊物料。
