一种锂电池回转窑的气体安全检测***、方法及介质A gas safety detection system, method and medium for a lithium battery rotary kiln 技术领域technical field
本申请属于锂电池回转窑领域，尤其涉及一种锂电池回转窑的气体安全检测***、方法及介质。The application belongs to the field of lithium battery rotary kilns, and in particular relates to a gas safety detection system, method and medium of a lithium battery rotary kiln.
背景技术Background technique
回转窑在建材、冶金、化工、环保等许多生产行业中，广泛地使用回转圆筒设备对固体物料进行机械、物理或化学处理，这类设备被称为回转窑。回转窑的应用起源于水泥生产，1824年英国水泥工J阿斯普发明了间歇操作的土立窑；1883年德国狄茨世发明了连续操作的多层立窑；1885英国人兰萨姆(ERansome)发明了回转窑，在英、美取得专利后将它投入生产，很快获得可观的经济效益。回转窑的发明，使得水泥工业迅速发展，同时也促进了人们对回转窑应用的研究，很快回转窑被广泛应用到许多工业领域，并在这些生产中越来越重要，成为相应企业生产的核心设备。Rotary kiln In many production industries such as building materials, metallurgy, chemical industry, environmental protection, etc., rotary cylinder equipment is widely used for mechanical, physical or chemical treatment of solid materials. This type of equipment is called rotary kiln. The application of the rotary kiln originated from cement production. In 1824, the British cement worker J Asp invented the earth shaft kiln with intermittent operation; Eransome) invented the rotary kiln, and put it into production after obtaining patents in Britain and the United States, and soon gained considerable economic benefits. The invention of the rotary kiln led to the rapid development of the cement industry, and at the same time promoted people's research on the application of the rotary kiln. Soon the rotary kiln was widely used in many industrial fields, and became more and more important in these productions, becoming the core of the production of corresponding enterprises. equipment.
锂电池在制备过程中，需要使用回转窑对锂电池的正负电极材料进行煅烧，以及用于废旧锂电池回收煅烧。回转窑在煅烧过程中伴随着的是废气的产生以及窑内高温造成的窑内压强突变，因此一般情况下，回转窑产生的废气都需要及时排出去，以避免炸窑引发安全事故。为了解决这个问题最常用和最直接的方法就是通过检测回转窑内的压强，从而控制回转窑的排气量。但通过控制排气量的方式控制窑内压强会有以下缺陷：During the preparation process of lithium batteries, it is necessary to use a rotary kiln to calcinate the positive and negative electrode materials of lithium batteries, as well as to recycle and calcinate waste lithium batteries. The calcination process of the rotary kiln is accompanied by the generation of exhaust gas and the sudden change of pressure in the kiln caused by the high temperature in the kiln. Therefore, in general, the exhaust gas generated by the rotary kiln needs to be discharged in time to avoid safety accidents caused by frying the kiln. The most common and direct way to solve this problem is to control the exhaust volume of the rotary kiln by detecting the pressure in the rotary kiln. However, controlling the pressure in the kiln by controlling the exhaust volume will have the following defects:
1)、压强对窑内的温度有直接的影响，如果压强改变会是的窑内的正常工作状态下的临界温度发生改变，从而影响窑内的正常工作；1) The pressure has a direct impact on the temperature in the kiln. If the pressure changes, the critical temperature in the normal working state of the kiln will change, thereby affecting the normal operation of the kiln;
2)、如果出现压强的骤变，强行通过泄压的方式降压，会使得排气口的安全隐患提升，极有可能出现排气口崩坏的现象，甚至是炸窑。2) If there is a sudden change in pressure, forcibly reducing the pressure through pressure relief will increase the safety hazard of the exhaust port, and it is very likely that the exhaust port will collapse, or even fry the kiln.

本申请所提供的锂电池回转窑的气体安全检测***，是基于锂电池回转窑正常工作状态下，或者说标准工作状态下内外温差和压强差的比值为依据进行检测的，而传统的气体安全检测***往往只关注窑内压强和温度，忽略了环境温度和环境压强，然而，真正导致安全隐患的是压强差的原理，例如在生活中大家都有这样的经历，一些密封包装的食品，到了高原或海拔较高的地方就会出现炸开的现象，显而易见的，包装袋内的压强是没有变化的，发生变化的是压强差，因此本申请基于该原理实现对回转窑内的安全气体检测，可消除因自身压强关注过高引发的安全事故，采用相对压强的概念，结合窑内温度，使得 回转窑始终保存在正常工作温度前提下控制窑内压强，从而提高了回转窑气体安全检测的可靠性。The gas safety detection system of the lithium battery rotary kiln provided in this application is based on the ratio of the internal and external temperature difference and pressure difference under the normal working state of the lithium battery rotary kiln, or the standard working state. The detection system often only pays attention to the pressure and temperature inside the kiln, ignoring the ambient temperature and ambient pressure. However, the principle of pressure difference is what really causes safety hazards. For example, everyone has such an experience in life. Explosion will occur in plateaus or places with high altitudes. Obviously, the pressure in the packaging bag does not change, but the pressure difference that changes. Therefore, this application is based on this principle to realize the safety gas detection in the rotary kiln. , which can eliminate safety accidents caused by too much attention to its own pressure. The concept of relative pressure is adopted, combined with the temperature inside the kiln, so that the rotary kiln is always kept at the normal working temperature to control the pressure inside the kiln, thereby improving the gas safety detection of the rotary kiln. reliability.
进一步的，所述K的取值为回转窑正常工作状态下，温差ΔT和压强差ΔP的比值。这里的工作状态是指，环境温度为正常温度，环境压强为正常压强，窑内温度和压强也在工作所需的正常范围或正常标准之内。Further, the value of K is the ratio of the temperature difference ΔT to the pressure difference ΔP under the normal working condition of the rotary kiln. The working state here means that the ambient temperature is normal temperature, the ambient pressure is normal pressure, and the temperature and pressure in the kiln are also within the normal range or normal standard required for work.
进一步的，所述回转窑内的温度和压强调节过程中采用分阶段的方式调节，且采用压强优先的原则，逐步调节以使窑内压强调节到正常水平。Further, the temperature and pressure adjustment process in the rotary kiln is adjusted in stages, and the principle of pressure priority is adopted to gradually adjust the pressure in the kiln to a normal level.
进一步的，所述分阶段的方式调节具体过程为：Further, the step-by-step adjustment specific process is as follows:
基于第一压强模块检测到的窑内实时压强和回转窑正常状态下的标准压强，计算出压强增量；Calculate the pressure increment based on the real-time pressure in the kiln detected by the first pressure module and the standard pressure in the normal state of the rotary kiln;
将压强增量分为N次调节，直至压强增量为0，调节过程中，基于压强调节优于温度调节的原则，每调节一次窑内压强，就对应调节一次窑内温度，以满足K维持不变或在一定范围内波动。The pressure increment is divided into N times of adjustment until the pressure increment is 0. During the adjustment process, based on the principle that pressure adjustment is better than temperature adjustment, every time the pressure in the kiln is adjusted, the temperature in the kiln is adjusted correspondingly to meet K maintenance. remain unchanged or fluctuate within a certain range.
采用压强增量分段条件，可避免压强突变引起温度的变化，或者说是为了避免压强突变后，窑内温度不匹配的温度，基于常识可以知道，当压强增高后，密封容器内所能承载的临界温度也会升高，例如高压锅原理，因此如果压强陡然降低，势必导致窑内温度超出临界温度从而引发安全隐患，因此必须采用一段压强一段温度的调节，才能保证窑内安全。而压强有线原则是因此压强降低后，临界温度会降低，这就会使得过高的温度会随着回转窑的排气口以高温废气的方式排除热量，因此必须是压强优先，如果是温度优先，当温度调节到位后，由于压强还未降下，而回转窑是持续加温的维持某一状态，因此压强未降下的时候，窑内温度仍会持续增加，所以必须优先调节压强。The segmental condition of pressure increment can avoid the temperature change caused by sudden pressure change, or in other words, to avoid the temperature mismatch in the kiln after a sudden pressure change. Based on common sense, it can be known that when the pressure increases, the capacity of the sealed container The critical temperature of the kiln will also rise, such as the principle of a pressure cooker. Therefore, if the pressure suddenly drops, the temperature in the kiln will inevitably exceed the critical temperature and cause safety hazards. Therefore, it is necessary to adjust a section of pressure and a section of temperature to ensure the safety of the kiln. The principle of pressure cable is that after the pressure is reduced, the critical temperature will decrease, which will make the excessively high temperature discharge heat with the exhaust port of the rotary kiln in the form of high-temperature exhaust gas, so the pressure must be given priority, if it is temperature priority , when the temperature is adjusted in place, because the pressure has not dropped, and the rotary kiln is continuously heated to maintain a certain state, so when the pressure has not dropped, the temperature in the kiln will continue to increase, so the pressure must be adjusted first.
进一步的，所述窑内压强调节过程中基于压强增量按等差数列的方式由小到大依次调节。Further, in the process of adjusting the pressure in the kiln, the pressure increment is adjusted sequentially from small to large in the manner of an arithmetic sequence.
进一步的，所述服务器采用RISC架构服务器，服务器的类型包括本地服务器、远程服务器和云端服务器三种选择。Further, the server adopts a RISC architecture server, and the types of the server include three options: a local server, a remote server and a cloud server.

实施例一Embodiment one

其中ΔT表示温差，ΔP表示压强差；用于实现对回转窑升温或降温的回转窑加热***18，以及用于控制回转窑排气口开度的阀门模块19；控制模块17，基于关系模型和窑内外实时温度和压强控制回转窑加热***18和阀门模块19以实现回转窑内的温度和压强调节，保持K维持不变或在一定范围内波动的前提下使窑内压强调节到正常水平。 The first aspect of the embodiment of the present application provides a gas safety detection system for a lithium battery rotary kiln, as shown in Figure 1, the system includes: a first temperature module 11 placed in the kiln for detecting the temperature in the kiln And the second temperature module 12 placed outside the kiln is used to detect the temperature outside the kiln; the first pressure module 13 placed in the kiln is used to detect the pressure in the kiln, and the second pressure module 14 placed outside the kiln is used to For detecting the pressure outside the kiln; the calculation module 15 responds to the first temperature module 11, the second temperature module 12, the first pressure module 13 and the second pressure module 14 to calculate the temperature difference and the pressure difference between the inside and outside of the kiln; the server 16 stores The relationship model between temperature difference and pressure difference is

Among them, ΔT represents the temperature difference, and ΔP represents the pressure difference; the rotary kiln heating system 18 for heating or cooling the rotary kiln, and the valve module 19 for controlling the opening of the rotary kiln exhaust port; the control module 17, based on the relational model and The real-time temperature and pressure inside and outside the kiln control the rotary kiln heating system 18 and the valve module 19 to realize the temperature and pressure adjustment in the rotary kiln, and adjust the pressure in the kiln to a normal level under the premise of keeping K constant or fluctuating within a certain range.
值得说明的是，本实施例所提供的锂电池回转窑的气体安全检测***是基于回转窑***的基础上进行的气体安全检测，也就是需要以包括回转窑在内的回转窑加热***18和阀门模块19等必要硬件结构所组成的设备。It is worth noting that the gas safety detection system of the lithium battery rotary kiln provided in this embodiment is based on the gas safety detection of the rotary kiln system, that is, the rotary kiln heating system 18 including the rotary kiln and the The equipment formed by necessary hardware structures such as valve module 19.
在另一方面的，本实施例中的压强模块(第一压强模块13和第二压强模块14)其本质是压力传感器，压力传感器是使用最为广泛的一种传感器。传统的压力传感器以机械结构型的器件为主，以弹性元件的形变指示压力，但这种结构尺寸大、质量重，不能提供电学输出。随着半导体技术的发展，半导体压力传感器也应运而生。其特点是体积小、质量轻、准确度高、温度特性好。特别是随着MEMS技术的发展，半导体传感器向着微型化发展，而且其功耗小、可靠性高。因此，本实施例中优选采用都是以半导体技术为主的半导体压力传感器作为压强模块。On the other hand, the pressure modules (the first pressure module 13 and the second pressure module 14 ) in this embodiment are essentially pressure sensors, and pressure sensors are the most widely used sensors. Traditional pressure sensors are mainly based on mechanical structural devices, and the deformation of elastic elements is used to indicate pressure, but this structure is large in size and heavy in weight, and cannot provide electrical output. With the development of semiconductor technology, semiconductor pressure sensors have emerged as the times require. It is characterized by small size, light weight, high accuracy and good temperature characteristics. Especially with the development of MEMS technology, semiconductor sensors are developing toward miniaturization, and their power consumption is small and their reliability is high. Therefore, in this embodiment, it is preferable to use semiconductor pressure sensors based on semiconductor technology as the pressure module.
优选地的，在本实施例中控制模块17基于其本质是一个控制器(英文名称：controller)是指按照预定顺序改变主电路或控制电路的接线和改变电路中电阻值来控制电动机的启动、调速、制动和反向的主令装置。由程序计数器、指令寄存器、指令译码器、时序产生器和操作控制器组成，它是发布命令的“决策机构”，即完成协调和指挥整个计算机***的操作。控制器所执行的计算机程序是按照图2所示的锂电池回转窑的气体安全检测方法的流程示意图所执行。控制器分组合逻辑控制器和微程序控制器，两种控制器各有长处和短处。组合逻辑控制器设计麻烦，结构复杂，一旦设计完成，就不能再修改或扩充，但它的速度快。微程序控制器设计方便，结构简单，修改或扩充都方便，修改一条机器指令的功能，只需重编所对应的微程序；要增加一条机器指令，只需在控制存 储器中增加一段微程序，但是，它是通过执行一段微程。具体对比如下：组合逻辑控制器又称硬布线控制器，由逻辑电路构成，完全靠硬件来实现指令的功能。由于本申请所提供的关系模型属于一类固定模型，对于某一应用场合下，其K为固定，因此本实施例中优选采用组合逻辑控制器。Preferably, in this embodiment, the control module 17 is a controller (English name: controller) based on its essence, which refers to changing the wiring of the main circuit or the control circuit and changing the resistance value in the circuit to control the start of the motor, The master device for speed regulation, braking and reverse. Composed of program counters, instruction registers, instruction decoders, timing generators, and operation controllers, it is the "decision-making body" that issues commands, that is, completes the coordination and command of the entire computer system. The computer program executed by the controller is executed according to the flow diagram of the gas safety detection method for the lithium battery rotary kiln shown in FIG. 2 . Controllers are divided into combination logic controllers and microprogram controllers, both of which have their strengths and weaknesses. Combination logic controllers are cumbersome to design and have a complex structure. Once the design is completed, it cannot be modified or expanded, but its speed is fast. The microprogram controller is easy to design, simple in structure, and convenient to modify or expand. To modify the function of a machine instruction, you only need to reprogram the corresponding microprogram; to add a machine instruction, you only need to add a section of microprogram in the control memory. However, it does so by executing a shred. The specific comparison is as follows: Combination logic controller, also known as hard-wired controller, is composed of logic circuits and completely relies on hardware to realize the function of instructions. Since the relational model provided in this application belongs to a type of fixed model, for a certain application occasion, its K is fixed, so a combinational logic controller is preferably used in this embodiment.
可选的，在一些实施例中，K的取值为回转窑正常工作状态下，温差ΔT和压强差ΔP的比值。正常工作状态是指通常情况下，环节温度、压强处于当下应用环境的正常水平，回转窑内的温度和压强符合工作指标的正常水准。换言之，在不同的应用场景或应用环境中，这个正常工作状态所表示的数值不是某一固定的数据，而是表示一个状态数据。Optionally, in some embodiments, the value of K is the ratio of the temperature difference ΔT to the pressure difference ΔP under the normal working state of the rotary kiln. The normal working state means that under normal circumstances, the temperature and pressure of the link are at the normal level of the current application environment, and the temperature and pressure in the rotary kiln meet the normal level of the working index. In other words, in different application scenarios or application environments, the value represented by the normal working state is not a certain fixed data, but represents a state data.
可选的，在一些实施例中，回转窑内的温度和压强调节过程中采用分阶段的方式调节，且采用压强优先的原则，逐步调节以使窑内压强调节到正常水平。Optionally, in some embodiments, the temperature and pressure in the rotary kiln are adjusted in stages during the adjustment process, and the principle of pressure priority is adopted to gradually adjust the pressure in the kiln to a normal level.
更为具体的，分阶段的方式调节具体过程为：基于第一压强模块13检测到的窑内实时压强和回转窑正常状态下的标准压强，计算出压强增量；将压强增量分为N次调节，直至压强增量为0，调节过程中，基于压强调节优于温度调节的原则，每调节一次窑内压强，就对应调节一次窑内温度，以满足K维持不变或在一定范围内波动。More specifically, the specific process of adjusting in stages is: based on the real-time pressure in the kiln detected by the first pressure module 13 and the standard pressure in the normal state of the rotary kiln, the pressure increment is calculated; the pressure increment is divided into N During the adjustment process, based on the principle that pressure adjustment is better than temperature adjustment, every time the pressure in the kiln is adjusted, the temperature in the kiln should be adjusted correspondingly, so that K remains unchanged or within a certain range fluctuation.
可选的，在一些实施例中，窑内压强调节过程中基于压强增量按等差数列的方式由小到大依次调节。在一个实例化演示中，当压强增量为900Pa时，可以依次按100Pa、300Pa、500Pa的方式依次调节，也就是上述的N值取3，第一次降低100Pa，第二次降低300Pa，第三次降低500Pa，经过3次调节后压强增量900Pa归于0。在实际调节过程中，N可以尽量取值大一些，以使得每次调节量的梯度更细，从而达到更高的安全指标。Optionally, in some embodiments, the pressure in the kiln is adjusted sequentially from small to large in an arithmetic progression based on the pressure increment during the adjustment process. In an example demonstration, when the pressure increment is 900Pa, it can be adjusted sequentially in the order of 100Pa, 300Pa, and 500Pa, that is, the above-mentioned N value is set to 3, the first time is reduced by 100Pa, the second time is reduced by 300Pa, and the second time is reduced by 300Pa. After three reductions of 500Pa, the pressure increment of 900Pa returns to 0 after three adjustments. In the actual adjustment process, N can be set as large as possible, so that the gradient of each adjustment amount is finer, so as to achieve a higher safety index.
可选的，在一些实施例中，服务器16采用RISC架构服务器，服务器16的类型包括本地服务器、远程服务器和云端服务器三种选择。可以根据应用场景的规模合理选择服务器类型，例如在大型工厂区域可采用远程服务器或云端服务器，对于一些小型工厂则选择本地服务器。服务器可以分成两大重要的类 别：IA架构服务器和RISC架构服务器，本申请中以RISC架构服务器为主，采用的CPU是所谓的精简指令集的处理器，精简指令集CPU的主要特点是采用定长指令，使用流水线执行指令，这样一个指令的处理可以分成几个阶段，处理器设置不同的处理单元执行指令的不同阶段，比如指令处理如果分成三个阶段，当第N条指令处在第三个处理阶段时，第N+1条指令将处在第二个处理阶段，第N+2条指令将处在第一个处理阶段。这种指令的流水线处理方式使得CPU有并行处理指令的能力，这使处理器能够在单位时间内处理更多的指令。同时，本申请中的服务器还配置有超大容量的存储空间以存储相应的数据。Optionally, in some embodiments, the server 16 adopts a RISC architecture server, and the types of the server 16 include three options: a local server, a remote server, and a cloud server. The server type can be reasonably selected according to the scale of the application scenario. For example, a remote server or cloud server can be used in a large factory area, and a local server can be selected for some small factories. Servers can be divided into two important categories: IA architecture servers and RISC architecture servers. In this application, RISC architecture servers are mainly used. The CPU used is a so-called RISC processor. For long instructions, use the pipeline to execute instructions. The processing of such an instruction can be divided into several stages. The processor sets different processing units to execute different stages of the instruction. For example, if the instruction processing is divided into three stages, when the Nth instruction is in the third In the first processing stage, the N+1th instruction will be in the second processing stage, and the N+2th instruction will be in the first processing stage. This pipeline processing method of instructions enables the CPU to have the ability to process instructions in parallel, which enables the processor to process more instructions per unit time. At the same time, the server in this application is also configured with a large-capacity storage space to store corresponding data.

S106：重复步骤S101-S105反复执行回转窑内的气体安全检测。S106: Repeat steps S101-S105 to repeatedly perform gas safety detection in the rotary kiln.
本实施例所提供的一种锂电池回转窑的气体安全检测方法采用固化逻辑的方式存储在锂电池回转窑的气体安全检测***的控制模块17中，使得控制模块17可以按上述的锂电池回转窑的气体安全检测方法进行执行，这种固化逻辑可以采用计算机程序或类似于PLC的控制逻辑指令的方式实现。优选的，本实施 例中选择以PLC逻辑语言的方式进行控制，以简化编程和运行难度。使其能更佳容易的应用在工业***中。The gas safety detection method of a lithium battery rotary kiln provided in this embodiment is stored in the control module 17 of the gas safety detection system of the lithium battery rotary kiln in a solidified logic manner, so that the control module 17 can rotate according to the above lithium battery The gas safety detection method of the kiln is implemented, and this solidification logic can be realized by a computer program or a control logic instruction similar to PLC. Preferably, in this embodiment, the PLC logic language is used for control, so as to simplify programming and operation difficulty. Make it easier to apply in industrial systems.
更进一步的，K维持不变或在一定范围内波动包括，基于压强调节优于温度调节的原则，同步调节回转窑内的压强和温度使得K维持不变，或先调节回转窑内的压强再调节回转窑内的温度使得K在一定范围内波动。显而易见的，采用压强增量和温度增量同时调节的方式效果最好，但会是的控制模块的运算复杂度呈几何倍增加。且本实施例中优选采用的是组合逻辑控制器，因此要尽量简化运算，故而采用先调节回转窑内的压强再调节回转窑内的温度这种固定逻辑，以更好的实现机器语言的编译。Further, keeping K constant or fluctuating within a certain range includes, based on the principle that pressure regulation is better than temperature regulation, synchronously adjusting the pressure and temperature in the rotary kiln so that K remains constant, or adjusting the pressure in the rotary kiln first and then Adjust the temperature in the rotary kiln to make K fluctuate within a certain range. Obviously, the method of adjusting the pressure increment and temperature increment at the same time is the best, but it will increase the computational complexity of the control module geometrically. And in this embodiment, the combined logic controller is preferably used, so the calculation should be simplified as much as possible, so the fixed logic of first adjusting the pressure in the rotary kiln and then the temperature in the rotary kiln is used to better realize the compilation of machine language .
更为具体的，本实施例中的压强增量按等差数列依次调节，其具体调节方式可参考上文锂电池回转窑的气体安全检测***中的调节方式。More specifically, the pressure increment in this embodiment is adjusted sequentially according to an arithmetic sequence, and the specific adjustment method can refer to the adjustment method in the gas safety detection system of the lithium battery rotary kiln above.
