主要系统设备介绍:
1. 制冷机选用日立RCUP30AU四台 2. 地源热泵控制系统通过
PLC
与制冷机一起完成水冷却. 3. 恒压给水系统IOP选用idec的pro-face产品,PLC选用MITSUBISHI的Q系列产品,变频器一期工程选用MITSUBISHI的FR-740 18.5KW产品,二期工程选用OMRON的3G3RV 18.5KW产品. 4. 过滤系统选用上海山姆环保设备有限公司产品. 5. 水槽的阀门选用CKD耐腐蚀阀门. 该项目已经投入使用2年,运行稳定,对电池的品质提升和环保效益明显.一种为采用西门子系统的控制方案，另一种是采用台达系统的控制方案。可以根据客户的要求来灵适搭配。
如变频器可使用国产化的产品。
一，传统控制方案
原来的使用方式是：用了2只温度传感器，配用2只温度
显示仪表
，顶部为100℃可调，中部为83℃可调。
83℃ 时为取酒温度，控制蒸汽的大小（温度和压力）和原料的进入全靠人工操作，缺点是：温度掌握不准确，原料泵控制又时大时小。所生产了的酒精不全格。
二，新的控制方案
新的控制方案采用了柔性控制算法，原料泵控制为可调泵的转速。全程操作为自动。只需人员监督设备即可。
考虑到蒸馏塔内压力和酒精供给量的不断变化，如采用传统的PID算法控制存在有：积分时间不断在变化的问题。所以我们采用了以温度给定值为控制参数，积分时间由系统自适应的控制方式。可以根据蒸馏塔内的环境变化动态地调节积分时间。
三，控制数学模型如下：
1，当 △T1<-e , 且dTi/dT>0 ,蒸气量减小；
2，当 △T1>-e , 且dTi/dT<0 ,蒸气量增大；
3，其它情况时，蒸气供给量不变。
△T1=T给定-Ti ； e 为控制死区（约为0.25℃~1℃）
四，过程描述：
当蒸气供给蒸馏塔加热时，随着温度的逐渐上升，达到“T给定+e”时，立刻关小蒸气阀门，减小蒸气量。直到温度再次回到：T给定+e点时，保持阀门开度。系统进入亚稳固态。
经过一段温度滞后时间后，当到达“T给定-e”时，立刻增加蒸气阀门开度。蒸馏塔温度又开回升……经过几个温度回滞的周期后，蒸馏塔的温度就会进入T给定温度的稳定状态。
五，系统构成：
人机界面（HMI）选用MT510，或KTP-178。所有控制操作可以在触模屏上完成，可编程控制器（
PLC
）采用台达ES系列，或者西门子S7200。可以方便的实现PID算法。
变频器选用台达的M系列变频器，或西门子MicroMaster440高效节能变频器。自带有RS485通迅口，可方便与PLC通讯。
温度采集可采用高精度热电偶+数显仪表（自带PLC接口）或PLC专用热电偶模块。
控制蒸汽选用智能型电动蒸汽阀。蒸汽阀两端的压差比较大，不允许调节阀有频繁动作，所以通过柔性控制方案电动调节阀门，可以很好控制蒸汽流量达到设定的控制温度。实现对蒸汽压力及温度实现高精度控制。PLC
，型号有6ES7 216-2AD23-0XB0 和 6ES7 216-2AD22-0XB0，并配有输入/输出模块EM223 和 EM 221数字量输入模块，并连接有西门子的SIMATIC HMI OP3型可编程操作面板作为人机控制接口。该机可加工成型0.2-2.3mm直径，长度在2.5-50mm的铜钉，设计生产能力为150至700ppm，目前运行速度约在600ppm。电气硬件组成方面包括：西门子S7-200的226系列PLC， SIMATIC HMI OP3型可编程操作面板，按钮开关操控面板，Altivar11型变频器，PEAsetting of industrial Ethernet card cp443-1 double click the line where cp443-1 is located, click the "general" button, change the name to PLC in the "name" column, click the "properties" button in the "interface" column, and enter the Mac and IP addresses. The transmission rate of industrial Ethernet is 100Mbps. 2.6. Structured programming the program in Siemens PLC is divided into operating system (i.e. step 7) and system user program. The operating system is used to handle the tasks of PLC startup, refreshing the image area of input and output process, calling user programs, dealing with interrupts and errors, managing storage area and communication. The user program is generated by the user to realize the automatic tasks required by the user. STEP7 places the program written by the user and the data required by the program in the block. The function block and function are equivalent to the program written by the user. The system function block and system function are the standard subroutines provided by the system to the user. These blocks are collectively referred to as logic blocks. Siemens PLC executes the user program in a circular way. Ob1 is an organization block for circular processing, which is equivalent to the main program of the user program. It can call other logic blocks or be interrupted by the interrupt program. After the startup is completed, call ob1 repeatedly, and other logic blocks can be called in ob1. The user program of PLC consists of several instructions, which are arranged in sequence in the memory. When there are no jump and block call instructions, the CPU starts from the first instruction and executes the user program one by one until the end of the user program. 2.7. The classic program design of rotary kiln preheater pusher program is the classic program of rotary kiln. There are 12 pushers in the preheater. They are responsible for pushing the materials in the preheater into the rotary kiln body. The 12 pushers form a circular structure and work according to the principle of opposite side pushing, which can prevent the phenomenon of excessive material on one side and empty material on the other side, That is, 1# after the work is finished, the push rod opposite to 1# starts to work after a period of delay.
