设备简介/Equipment introduction:

    PAM自动加药系统是一种具有投药、搅拌、液体输送、自动控制于一体的成套设备,它被广泛应用于电厂的原水、锅炉给水、油田地面集输脱水处理系统,石油化工各种加药系统和废水处理系统。如投加混凝剂、磷酸盐、氨液、石灰水、缓蚀剂、阻垢剂、杀菌灭藻剂等。

 

    The PAM automatic dosing system is a complete set of equipment with dosing, mixing, liquid delivery, automatic control which is widely used in the raw water of the power plant, the water supply of the boiler, the oil ground gathering and dewatering process system, various dosing system of petroleum chemical and wastewater treatment system, such as dosing the coagulant, phosphate, ammonia, lime water, corrosion inhibitor, scale inhibitor, bactericide and algaecide and so on.

工作原理/Principle:

    本装置是粉状高分子凝絮剂的自动连续配置投加系统。干粉絮凝剂从螺旋推进器内进入预混器与清水进行预混,被湿润的物料进入配制槽进行稀释,按要求浓度进行配制;配制溶液从配制槽经熟化槽再进入储存槽,当储存槽液位处于高位时,配制过程自动停止,当溶液下降到中液位时,重新自动启动配料过程。配制槽和熟化槽均设置多桨叶搅拌器,充分保证絮凝剂的稀释和熟化。当系统产生报警时,证明系统内可能要检查修理某部位。若为液态絮凝剂则由螺杆泵直接投加到配制槽中。配制过程中,絮凝剂量为恒定,水量按比例投加或(水量为恒定,絮凝剂按比例投加)。从而保证在整个工作过程中,配制溶液浓度不变。配制溶液由储存槽进入加药泵、由加药泵打入流量计进行在线稀释后,进入管道混合器,实现絮凝效果。加药装置还可根据用户不同工艺流程的要求,进行有针对性的设计、配置必要的部件,实现自动远程控制等功能。

 

    The device is a continuous dosing system that can automatically configure the powder polymer flocculation agent. Dry powder flocculants go into the pre-mixer through the screw propeller to pre-mix with water, wetted material goes into a mixing tank for dilution to the required solution concentration; the prepared solution goes into the storage tank through the mixing tank and the curing tank, when the storage tank liquid level is at high level, the preparation process automatically stops, when the solution liquid level decreases to the middle level, the preparation process restarts. Mixers are equipped inside the mixing tank and the curing tank to ensure a full dilution and curing of the flocculant. When the system generates alarm, it proves a need to check and repair some part inside the system. The liquid flocculant is directly added into the mixing tank by the screw pump .In the process of preparation, the amount of flocculant is constant while water is added according to the proportion or (the water amount is constant, flocculating agent is added according to the proportion). In order to ensure the  solution concentration unchanged during the whole process, the prepared solution goes into the dosing pump trough the storage tank, then pumped into the flow meter by the dosing pump for inline dilution, and then into a pipeline mixer to realize the flocculation effect. Dosing device can be designed according to user's different processes requirements and configure necessary components to realize automatic remote control function etc.
