SJM降膜蒸发浓缩器系列

SJM SERIES THREE EFFECT FALLING-FILM CONTINUOUS FEEDING CONCENTRATOR

本公司广泛结合进口浓缩设备与其它行业浓缩设备所长，并结合物料的特性，设计与开发出系列SJM型三效(双效、单效)降膜连续进料浓缩器。该设备的特点如下：

1. 连续进料与出料，系统稳定，操作方便。本系列设备在工作时，仅需在进料初期按要求调节好各项参数，同时保证物料连续稳定供应，调节方便，可连续稳定高效进行浓缩并达到合格的比重要求并可同时回收溶媒。

2. 浓缩比重大(可达1.25-1.28)，热效率高，节能。在本系统结构上，我们采用优化的设计方案，使蒸发传热系数达3400-3800w(m2·K)，这对物料的浓缩是非常适合与有利的，主要原因是物料在加热管中成膜状快速流动，同时加热温度差较小(仅为8-10℃)，蒸发温度低，物料在进入蒸发器后能形成快速闪蒸，物料在加热管中的停留与受热时间短，对物料的粘度适应范围广(50-500cp),受热均匀不易结晶析出与结焦，对有效成份的破坏量小，热能利用充分，节能。

3. 便于采用的控制方法。由于SJM系列浓缩的流程主要以各效的温度为控制参数，系统运行时各参数稳定，便于采用的自动控制(PLC与人机界面控制)，而且控制装备成本相对较低，对于生产实现全自动控制有较大的便利。

4. 结构设计、合理。在结构上，我们采用优化的设计方案，对进料时的料液分布与在管内的流动我们采用的液体分布装置，使物料能均匀地进入各加热管，同时，选用优质进口的内壁镜面管作加热管，使物料在管内的流动阻力小、速度快，不易析出结垢。为提高浓缩的收率，系统装备的雾沫捕集器，消除雾沫夹带的能力强，分离效率可达96-99%，而且阻力降小。

We integrated the highlight of imported concentration equipment with that of the counterparts, based on the characteristics of the material, research and develop SJM type three-effect (double effect, single effect) falling-film continuous feeding concentrator.

The equipment feature is as follows:

1. Continuous feeding and discharge, stable and convenient operation. The only operation package of setting of different parameters at the beginning of feeding, assurance of reliable and stable feeding supply and easy regulation can certainly produce continuous, stable and efficient concentration, get qualified density and simultaneously recover solvent.

2. Large concentration density, (1.25-1.28), high heat efficiency and effective energy-saving fruit. To this system, we used optimum to leave a vaporization heat transmission coefficient of 3400-3800w(m2.k),which is very benefit to concentration of Chinese extraction liquid. The cause for it is that the material flows quickly with the form of film inside the acceleration pipe, and simultaneously, the temperature difference for heat is somewhat small, (just 8-10℃).The material can form quick flashing, the medicine liquid stays and be heated for short time; the adaptation scope of material viscidity is wide, (50-500cp); the even heating excludes crystallization, and then to deposition and even coke. So it features little destroy to effective element, full utilization of heat energy and fruitful energy-saving.

3. Convenient to employment of advanced control mode. The temperature index for series SJM concentration flow is mainly subject to the temperature of each of effect. Each of parameter keeps stable during system performance, which benefits the utilization of advance control unit featuring (PLC and man-machine interface control) and leaves the lower cost of control equipment, makes the production of Chinese drug by automatic control great convenience.

4. Advanced and reasonable structure. We used optimum design scheme. Advanced distribution device is responsible for liquid distribution during feeding and flow inside the pipe to make the material able to enter heating tube evenly. Simultaneously, the heating tube, made by qualified and imported inner-wall mirror tube, can reduce the flow resistance to the material inside the tube, increase the flow speed, and prevent crystallization and deposition. To lift concentration efficiency, the advanced mist collector can eliminate mist. The separation efficiency can be of 96-99%, with low resistance.
