Technical Field

The embodiment of the application relates to the technical field of activated coke desulfurization and denitrification and dry quenching, in particular to a monitoring system and a monitoring method for activated coke desulfurization and denitrification and dry quenching.

Background

Sintering/pelletizing flue gas and dry quenching flue gas are one of the main pollution sources of iron and steel enterprises. Under the new era background that the environmental protection situation is increasingly severe and the environmental protection requirements are gradually increased, especially along with the implementation of the ultra-low emission modification of the steel industry and the promotion of the ultra-low emission evaluation monitoring work of the steel industry, stricter requirements are provided for the sintering/pelletizing flue gas pollutant emission and the upgrading and modification of pollution treatment facilities.

The desulfurization and denitrification technology of the active coke is a dry flue gas treatment technology which utilizes the adsorption function of the active coke, simultaneously removes sulfur oxides, nitrogen oxides and smoke dust in the flue gas and recovers sulfur resources. The active coke desulfurization and denitrification technology can remove sulfur dioxide and nitrogen oxides, has a removing effect on smoke dust, mercury, dioxin, heavy metals, volatile organic compounds and other trace elements in flue gas, and has the advantages of simple process, low cost, resource utilization and the like. After the activated coke desulfurization and denitrification technology was developed in the 60 th of the 20 th century, the industrial popularization and application began in the 80 th. At present, the technology is applied to treating various industrial waste gases such as coal-fired boiler flue gas, sintering/pelletizing flue gas, waste incineration flue gas and the like, and relates to a plurality of key industries such as chemical industry, electric power, metallurgy and the like.

The dry quenching technology is that red coke is loaded from the top of a dry quenching furnace, low-temperature inert gas is blown into a red coke layer of a cooling section of the dry quenching furnace by a circulating fan to absorb the sensible heat of the red coke, the cooled coke is discharged from the bottom of the dry quenching furnace, high-temperature inert gas discharged from an annular flue of the dry quenching furnace flows through a dry quenching process boiler to carry out heat exchange, the boiler generates steam which can be used for power generation, the cooled inert gas is blown into the dry quenching furnace again by the circulating fan, and the inert gas is recycled in a closed system. The dry quenching process is superior to wet quenching in energy saving, environment protection, coke quality improvement and other aspects.

However, for the activated coke desulfurization and denitrification and dry quenching device built by enterprises, the degree of understanding of an operator on a new device is low, the operation proficiency is low, warning information is not paid attention to and other reasons, and the conditions that the device is on fire, the failure analysis is difficult and the like often occur. And the active coke desulfurization and denitrification and dry quenching device needs personnel to carry out field equipment management, information communication and fault analysis, but the field communication and analysis can not be carried out due to some special reasons such as epidemic situation isolation, so that the equipment can not run safely.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic diagram of a monitoring system for desulfurization, denitrification and dry quenching of active coke according to an embodiment of the present application. As shown in fig. 1, the system includes:

an acquisition module 110, configured to acquire operation data in the activated coke desulfurization and denitrification process and the coke dry quenching process, where the operation data is derived from pre-selected parameters, and the parameters include: technical parameters and process parameters.

The technical parameters refer to relative data measured by equipment under specified detection conditions, generally performance test reports made for design or production, and the process parameters refer to a series of basic data or indexes of a process for completing a certain work, namely, the basic data or indexes constitute the content of process operation or design.

Important technical parameters and process parameters are selected in advance as the basis for evaluating the process and the production condition, for example, data of production process sensors, data of a control system, data of environmental working conditions, data of equipment operation and the like can be selected. In the examples of the present application, the process parameters select some important parameters of desulfurization and denitrification of activated coke: flue gas temperature, flue gas flow, flue gas pressure and SO in flue gas₂Concentration of (3), NO in flue gas_xConcentration of (1), O in flue gas₂Concentration of (2), ammonia slip amount, etc., and the techniqueThe parameters can be selected as follows: the pressure of the fan centrifugal ventilator refers to boosting, the rotating speed of a fan rotor, the material level of the adsorption tower and the like, and the actual data of the parameters at the current moment of the active coke desulfurization and denitrification/dry quenching process are collected to form the operation data of the active coke desulfurization and denitrification and dry quenching process.

And the intelligent data acquisition gateway 120 is connected with the acquisition module through an industrial Ethernet, and is used for reading the operating data through the industrial Ethernet and transmitting the read data to the cloud platform through a mobile communication network.

The gateway works in an application layer and is mainly used for connecting two different networks, and meanwhile, the gateway can also communicate with hosts of different networks at the same time. Since hosts of different networks of the internet are not able to communicate directly, gateways must be established to communicate with each other. In short, a gateway is a network that manages IP addresses between different network segments to other networks. The intelligent data acquisition gateway connects the field device with the cloud platform to forward data between the field network and the outside of the cloud, for example: the external network comprising the field devices and forming the network A and the cloud platform is B, the IP address range of the network A is 192.168.1.1-192.168.1.254, the subnet mask is 255.255.255.0, the IP address range of the network B is 192.168.2.1-192.168.2.254, and the subnet mask is 255.255.255.0. The TCP/IP protocol also determines A, B that the hosts in the two networks are in different networks according to the subnet mask (255.255.255.0), if a host in network a, such as a PLC (Programmable Logic Controller), wants to communicate with a host in network B, such as a cloud platform, it needs to allocate an address in IP of network a and IP of network B in advance as a gateway 1 (such as an intelligent data acquisition gateway) and a gateway 2 (a gateway preset by an external network), the host in network a forwards the packet to its gateway, i.e., gateway 1, and then gateway 1 forwards the packet to gateway of network B, i.e., gateway 2, and gateway 2 forwards the packet to a host in network B.

Moreover, the intelligent data acquisition gateway selected by the application also has the functions of data acquisition, data storage, protocol conversion, data forwarding, edge calculation and the like, so that the operation data domain acquired by the field device is read.

Aiming at the problems that the current industrial communication protocol standards are not uniform and incompatible, and a large number of 'dumb devices' which do not open protocols exist, the intelligent data acquisition gateway can comprise a protocol gateway port and an acquisition gateway port, wherein the protocol gateway port is a part which provides a serial port/a network port to acquire intelligent device data, supports the acquisition of data in a bus communication protocol mode, and can convert various different acquisition protocols into standard network protocols and send the standard network protocols to a control center. The collection gateway port is a part for providing an IO interface to collect dummy equipment data, supporting data acquisition in a signal conversion mode, uniformly packaging various types of IO data, packaging into a standard network protocol and sending the standard network protocol to a monitoring center.

For the problem of tolerance of industrial communication protocols, the intelligent data acquisition gateway supports various protocols, supports main stream protocols such as ModbusTCP, OPCUA and MQTT which are uplink to the industrial gateway, and for the uplink communication protocols: the system can analyze a standard ModbusTCP acquisition protocol, a plurality of MQTT acquisition protocols of different manufacturers and different gateway models based on an MQTT communication mechanism, and a client acquisition protocol based on OPCUA. And protocol analysis of descending mainstream protocols ModbusRTU, PPI, MPI, DF1, SNP, ProfiNet, EtherCAT, CCLink and the like is supported.

This application with intelligent data acquisition gateway access on-the-spot industrial switch, through industrial ethernet, realize carrying out real-time communication with SOx/NOx control PLC. The intelligent data acquisition gateway performs protocol access, protocol analysis, protocol package and the like, reads the operation data, and transmits the read operation data to the cloud platform through a mobile communication network such as a 4G network.

In an embodiment of the present application, the activated coke desulfurization and denitrification process and the coke dry quenching process are controlled by a programmable logic controller, and the system further includes:

and the defining module is used for defining the function focus related to the parameters in the programmable logic controller as a function block focus so as to store the running data in a first data block DataBlock.

In the embodiment of the application, a Programmable Logic Controller (PLC) is adopted to control the desulfurization and denitrification process and the dry quenching process of the active coke. The overall program of the PLC is composed of individual program blocks, but FC (Function) written by users is a logic block without memory. They do not have data storage, i.e. memory for storing module parameter values. Therefore, when the function is called, all interfaces must be switched on. A function FC contains a program that is executed when the function is called by another logic block. These functions may be used for the following purposes, for example: mathematical functions, such as returning a result based on an input value. Process functions such as a single controller operating in a binary logic associative manner. The same function may also be called multiple times at different locations within a program.

Although functional blocks may also work with temporary variables. But the temporary variable is not saved in the data block but is only available for use during the cycle time of one cycle.

In the PLC, a Data Block (DB) refers to a location for storing variable data operated by a user program, and there is no program in the data block, and the maximum size of one DB varies depending on a CPU. The data block DB may be shared, and each OB (Organization block), FC (Function), and the like reads and writes data. A data block (or memory) differs from a logic block in that it contains not instructions, but rather user data. Contained in the data block are variables for user program processing, the structure of the global data block can be defined as required,

since FC cannot store data in operation, the application considers that function focus related to preselected parameters can be defined as function block focus, and since the function block has its own storage area, data of these parameters in the function block in the active coke desulfurization and denitrification process will be stored in the corresponding background data block and will not be removed.

The function block FB (or function block) is a logic block, but it can keep the input variable, the output variable, the channel variable and the static variable in the background data block. These variables are available even after the module processing process is complete. They are therefore also referred to as "memorised" modules. Background data blocks (also called fixed data blocks) generally refer to the parts of data blocks belonging to function blocks, and the access rights of the background data blocks are in principle only open to the function blocks to which they belong. The maximum size of the background data block is related to the CPU model and will vary accordingly. The variables listed in the function block determine the structure of the background data block.

Function blocks may be used to perform tasks that cannot be performed by function, for example, when a timer and counter are required in a module, when a piece of information must always be saved in a program, when an operation mode is preselected by a button. Other logic blocks execute function blocks when they call them. Function blocks may also be called multiple times at different locations within a program. Thus, programming of complex functions that are often repeated can be simplified. The invocation of a function block is referred to as an instance. Each instance of a functional block is associated with a memory area containing data required for processing the functional block. The memory area can be used for data blocks automatically generated by software, and one memory area can also be used as multiple backgrounds for multiple instances in one data block.

The FC related to the selected parameter is defined as the FB, and the FB can automatically store the data in the background data block to which the FB belongs when being executed, so that the data of the parameter in execution can be stored in the PLC without additional collection.

In an embodiment of the present application, the defining module is further configured to define, at the programmable logic controller, a data processing foucault, where the data processing foucault is used to process the operating data into evaluation data;

because the collected operation data are disordered and rough data, subsequent cloud platform display is not utilized, measures such as fold line change statistics, synchronization comparison and the like are further adopted to form evaluation data from the operation data, and the current overall condition of the active coke desulfurization and denitrification/dry quenching technological process can be directly and specifically displayed through the evaluation data.

Further, the processing process of the running data is that a FB for data processing is defined in the PLC through a definition module, in other words, in the original PLC running program, the processing process of the collected parameters is added, the running data is processed and stored in the PLC after being collected, the data processing is completed by the functions of the PLC, all other operations except the displayed data are performed in other operation blocks of the PLC, and for example, the processing process of the parameters, such as sorting, arithmetic operation, classification and synthesis, is defined as Fouction block and added in the original PLC program. Since the assessment data subsequently needs to be read out, this incremental processing procedure is also in FB form,

and, carrying on the data processing in PLC can also reduce the mobile network like 4G network data traffic, so that the actual situation that the cloud platform can be reflected on the scene fast, only store the data used for cloud platform display finally in the data block DB, because the PLC on the scene is the redundant system, the systematic margin of oneself is greater, and the cloud platform server needs many kinds of calculation load relatively great, reduce the operation of the data as far as possible, in order to lighten the load of the platform, in the case that the 4G network is stable, the display of the cloud platform is almost the same with the on-the-spot display like this. The stored assessment data can be directly used for visual display by the cloud platform.

The intelligent data acquisition gateway is further used for reading the evaluation data in the programmable logic controller through an industrial Ethernet and transmitting the read data to the cloud platform through a mobile communication network.

After the PLC is adopted to generate the evaluation data for display, the intelligent data acquisition gateway reads the data from the PLC and sends the data of the readings to the cloud platform.

And the cloud platform 130 is connected with the intelligent data acquisition gateway through a mobile communication network, and is used for receiving the data sent by the intelligent data acquisition gateway and performing visual display according to the received data.

The cloud platform has a powerful remote visualization function and is rich in data interface forms, the cloud platform has two serial port communication modes, namely a CAN bus and an RS-485 bus, which are most commonly used, and also comprises other serial port communication modes, such as RS-232, RS-422, a USB interface, an Ethernet interface and a GPRS module interface, and the cloud platform also has picture elements with real texture, such as a column diagram, a broken line diagram, a 3D remote picture schematic diagram, a field flow schematic diagram and the like.

And after receiving the data transmitted by the intelligent data acquisition gateway, the cloud platform stores the data in a real-time historical database of the server side and displays the data to reflect the actual situation of the site. The visual display mode for the cloud platform can be as follows: the cloud platform pre-builds a visual on-site flow chart of the on-site production process and displays specific data below, such as when the fan inlet pressure of the analytical tower is too low in the assessment data. The relevant functions of the fan in the site map, namely the fan and the air supply channel are changed into preset colors like red to remind a user, and meanwhile, the site map displays xxx fan inlet pressure alarm, and the numerical value is xxxx.

In another visual display mode, the cloud platform can establish a 3D remote view of the whole active coke desulfurization and denitrification and dry quenching system, a fan pipeline, a transportation system and the like are displayed in a 3D model mode, and when a user clicks a model of equipment related to a certain process, evaluation data corresponding to the equipment is displayed in a report form, an object statistic mode and the like.

The cloud platform can also assign an ID to the field device, and when the received data contains an abnormal condition and the time and date of the abnormal condition, the ID, time and date of the fault device are also shown together, such as time xxx, Idxxxx, date xxx, IDxxx, event: and xxxx blower inlet pressure alarm, and the abnormal value is xxxx.

When a plurality of active coke desulfurization and denitrification and dry quenching systems distributed at different places exist, the cloud platform can record the position information of each system in advance, further, the position information of each device in the system can be recorded, GIS maps of a plurality of systems are established, when a certain parameter in the evaluation data is detected to be abnormal, the system and the device with the fault are displayed on the GIS maps, and managers can know the position information of the system and the device with the fault to maintain in time. The cloud platform sets up each managers' authority in advance, and the managers who possess corresponding authority can access the data of corresponding equipment and system, avoids data leakage or managers maloperation scheduling problem, based on the management authority, when data is unusual, with fault department equipment and system notice possess the managers who corresponds the authority, realize the corresponding warning of information. And based on the authority management of the cloud platform, hierarchical layering is realized, and managers respectively play their roles.

The cloud platform can realize functions of platform integrated report analysis, fault management, trend curve, equipment management and control and the like based on the received data, and process data is collected, processed and displayed in an all-around and multi-angle mode, so that remote real-time collection monitoring, statistical analysis, data and process flow optimization and the like of process information are realized.

In an alternative embodiment of the present application, the cloud platform employs HTML5 front-edge technology framework.

Further, the cloud Platform adopts a Platform as a Service Platform-as-a-Service mode.

HTML5 is the result of W3C (World Wide Web Consortium) collaborating with the whatwg (Web Hypertext Application Technology work group), and in 2006 both parties decide to collaborate to create a new version of HTML, HTML 5. HTML5 now has for previous web languages: the new features should be based on HTML, CSS, DOM, and JavaScript; reducing the need for external plug-ins (such as Flash); more excellent error handling; more markup in place of scripts; HTML5 should be independent of device, etc. features.

Platform-as-a-Service is a kind of cloud Service, which can be divided into three major categories, IaaS (Infrastructure-as-a-Service Infrastructure Service), PaaS (Platform-as-a-Service) Platform Service, SaaS (Software-as-a-Service) Software Service, PaaS provides a Software deployment Platform (runtime), abstracts hardware and operating system details, and can be seamlessly extended (scaling). Developers only need to pay attention to own business logic and do not need to pay attention to the bottom layer.

Cloud computing (cloud computing) is one type of distributed computing, and means that a huge data computing processing program is decomposed into countless small programs through a network "cloud", and then the small programs are processed and analyzed through a system consisting of a plurality of servers to obtain results and are returned to a user. Cloud computing is simply understood as simple distributed computing, solves task distribution, and merges computing results. Thus, cloud computing is also known as grid computing. By the technology, tens of thousands of data can be processed in a short time (several seconds), so that strong network service is achieved. Cloud computing has the advantages of high flexibility, expandability, high ratio and the like.

The cloud platform server sorts, optimizes, counts and analyzes the evaluation data and then issues the data in an HTML5 mode for equipment access, and the HTML5 mode can be compatible with various kinds of equipment, so that managers can monitor the data in real time in a convenient mode.

The method adopts a PaaS mode, and the time required for coding new applications can be greatly reduced through pre-coding application program components (such as workflow, directory service, security function, search and the like) arranged in a platform through a PaaS development tool, so that the coding time is reduced. The platform, namely the service component, can expand the capability of a development team without increasing staff with necessary skills and improving the development capability without increasing staff. Some PaaS service providers offer development options for a variety of platforms (e.g., computers, mobile devices, and browsers) that enable faster and easier development of cross-platform applications and more easily for a variety of platforms, including mobile platforms. The pay-as-you-go mode used by the PaaS service can be used without a whole set of purchased advanced development software, commercial intelligence and analysis tools, so that the cost is reduced, and the PaaS service is more economical and practical. The PaaS model enables a development team to collaborate in a development project even if members of the development team are far away from each other by accessing a development environment through the Internet, and supports a development team with a dispersed geographical position. The PaaS provides all functions required for supporting the complete life cycle (generation, test, deployment, management and update) of the Web application program in the same integrated environment, and can effectively manage the life cycle of the application program.

In an optional embodiment of the present application, the intelligent data collection gateway further includes:

P2P (english full peer-to-peer) is a new computing model that emphasizes logical peering between nodes. The P2P network is also commonly referred to as a peer-to-peer network, where each participating node contributes a portion of the computing power, storage power, and network connectivity. These capabilities are directly accessible as shared resources by other peer nodes over the network. And no intermediate entity is needed in the access process, so each node is a user of the resource and the service and a provider of the whole resource and service. Each network node is interconnected in a flat topology. Nodes without special positions in the whole network can respond to any peer node by each node to provide resources.

According to the method, the intelligent data acquisition gateway and the cloud platform are used as two equal nodes to form a P2P Network, and VPN (Virtual Private Network) is adopted for communication between the networks and is a communication method commonly used for connecting Private networks of medium-sized and large-sized enterprises or groups. The virtual private network provides confidentiality by preventing interception and sniffing through a cryptographic Tunneling Protocol, also allows sender identity verification to prevent identity forgery, and provides message integrity by preventing information from being modified.

The right is released by adopting the P2P structure, the defects that the load of a central node is large in the weight collection formula, and the whole system cannot normally operate due to faults are overcome, the response speed between the nodes can be accelerated, and the freedom between the nodes is ensured. And the use of a VPN can satisfy the customer's absolute security requirements for data.
