FIG. 2 is a block diagram of an ash removal system;

the ash removal system mainly comprises a DCS collecting and distributing system formed by ZY100-Q20 and ZY200-Q through a field bus. ZY100-Q20 is installed on site, the pulse valve is controlled in a blowing mode according to a cured program, and ZY200-Q controls ZY100-Q20 of each bin through a field bus.

The ash removal system has the following functional characteristics in detail:

intelligent: the results are shown in the parameterization of ZY100-Q20 and ZY 200-Q. By changing the value of the ZY200-Q bin quantity parameter, the blowing of 1-30 bins can be controlled; by changing the value of the number parameter of the ZY100-Q20 pulse valve; the blowing of 1-20 pulse valves per bin can be changed; the arbitrary sequential blowing of the bin can be controlled by changing the value of the ZY200-Q blowing sequence parameter; by changing the value of the ZY200-Q injection control mode parameter, ZY100-Q20 can be injected sequentially, and bin differential pressure or mixed injection can be realized; the dust removing system collects the air bag pressure before and after injection and the differential pressure of each bin, and can accurately determine whether the pulse valve of the bin is good or bad or has leakage; that bin differential pressure is too high, multiple blows may be made to determine the blowing effect or to replace the bag. All the characteristics can obviously improve the blowing effect; the labor intensity can be saved by the aid of the functions, and faults are processed in a sprouting state; the parameter values are only changed in all the functional software, the number of ZY100-Q20 is not changed in hardware or only increased through a network, and the cost and construction are low and simple; the comprehensive result achieves the purposes of saving operation cost, energy conservation and emission reduction.

Digitization: the ash removal system is characterized in that ZY100-Q20 are connected together through a field bus, and the field bus is digital transmission through ZY200-Q centralized control, so that the anti-interference performance and reliability are improved, the installation and later maintenance cost is reduced, and the purposes of energy conservation and emission reduction are achieved.

And (3) modularization: the ash removal system mainly comprises ZY100-Q20, all the ZY100-Q20 installed in the warehouse are the same, and ZY200-Q is also in a modularized design, and a power panel, a communication panel, a main board and an outward expansion function board are all used by personnel without training and after sales due to the modularized design, so that the later operation and maintenance cost is saved, and the purposes of energy conservation and emission reduction are achieved.

Standardization: the characteristics of nonstandard products of the bag-type dust remover determine the diversity of mechanical and electrical designs; different manufacturers use different PLC models, different programming modes, different hardware designs and the like, so that the cost is increased for installation and later operation and maintenance; the ash removal system is suitable for ash removal control of all bag-type dust collectors, and only the number and parameter settings of the different bag-type dust collectors ZY100-Q20 are different, so that unified standardization of hardware and software is achieved, the cost of early installation and later maintenance is facilitated, and the purposes of energy conservation and emission reduction are achieved.

The Internet of things: the existing internet of things devices basically consist of singlechips with different digits, such as wifi functions, 4G functions and the like; the ZY200-Q network controller of the ash removal system is composed of a 32-bit ARM single-chip microcomputer which is popular at present, has the advantages of congenital cost and convenience for constructing the function of the Internet of things, is beneficial to the cost of early installation and later maintenance, and achieves the purposes of energy conservation and emission reduction.

The ash removal system is an improvement innovation by forming a DCS distributed control system by ZY200-Q and ZY100-Q20 by a field network; meanwhile, the 2 great current difficulties of the current bag-type dust remover are solved: a. the quality and leakage of the pulse valve, b, the period and the quantity of cloth bag replacement cannot be found. These 2 problems plague the cost of operation and maintenance and the labor intensity of personnel in the later stage of bag dust removal for a long time. The ash removal system can accurately and timely find the quality of the pulse valve, increases the cloth bag replacement period, reduces the number of cloth bags to be replaced, saves the later operation cost, and achieves the purposes of energy conservation and emission reduction.

In summary, the ash removal system achieves the purposes of energy conservation and emission reduction by means of intellectualization, digitalization, modularization, standardization, internet of things, improvement and innovation and the like, and solves the defects of the current PLC control mode.

ZY100-X20 is shown in FIG. 6 below

The ash discharging system has the following functional characteristics:

The ash discharging systems of different ash hoppers can be controlled by changing the number parameter values of the ZY200-X ash hoppers; the ash discharging system with single ash discharging hopper or double ash discharging hopper can be controlled by changing the parameter value of the ash discharging hopper; ZY200-X also provides 4 modes of operation: a. the time control mode, the ash bucket sequence timing ash discharging b, the material level control mode, the ash discharging c according to the ash bucket up-down material level switch control, the field manual mode, the field device manual control through an operation box (the field device interlocking and interlocking are controlled by a program, so that the ash discharging system field low-voltage cabinet circuit is simple), the maintenance mode, the field device manual control through the operation box, and compared with the field manual control, the field device manual control method has no interlocking and interlocking functions. All the functional software only changes the parameter value, the hardware is not changed, and the cost and the construction are low and simple; the level and the number of personnel required by the later maintenance can be reduced; the comprehensive result achieves the purposes of saving operation cost, energy conservation and emission reduction.

Digitization: the dust discharging system is a DCS collecting and distributing system formed by connecting ZY 200-X100-X20 together through a field bus, wherein the field bus is digital transmission, so that the anti-interference performance and reliability are improved, the installation and later maintenance cost is reduced, and the purposes of energy conservation and emission reduction are achieved.

And (3) modularization: the ash discharging system mainly comprises ZY100-X20, and ZY100-X20 installed in the ash discharging site low-voltage cabinet is the same as ZY100-Q20 in some cases, except for different curing procedures;

the ZY200-X is also in a modularized design, and a power panel, a communication panel, a main board and an external expansion function board can be exchanged as the ZY200-Q, but the curing programs are different; the modularized design enables maintenance personnel to avoid training and after sales, saves the operation and maintenance cost in the later period, and achieves the purposes of energy conservation and emission reduction.

Standardization: as with the ash removal system, the ash removal system is suitable for ash removal control of all bag-type dust collectors, and only different bag-type dust collectors ZY100-X have different parameter settings or different control modes are selected, so that unified standardization of hardware and software is achieved, the cost of early installation and later maintenance is saved, and the purposes of energy conservation and emission reduction are achieved.

The Internet of things: the same as the ash removal system.

Improvement innovation: the interlocking function of the field device of the ash discharging system is solidified in the program, so that the principle wiring of the low-voltage cabinet is very simple; the ash discharging system low-voltage cabinet is placed on site, so that maintenance is facilitated, and installation cost is saved; each path of current switch is added to a driving loop of the field device, so that the field device is not damaged; the purposes of energy conservation and emission reduction are achieved.

FIG. 5 is a composition diagram of a fan system;

FIG. 6 is a block diagram of a blower system;

the fan system directly comprises a DCS upper computer and a fan field acquisition cabinet, and forms a DCS distributed system through a field bus. The fan system is dominant in the ZY1000 large-scale control system, and the main interface of the man-machine interface of the DCS upper computer is mainly the fan system; the other subsystems are connected to the DCS upper computer through the field bus, the DCS upper computer can control the other subsystems according to the running state of the fan, and the running of the fan system can be regulated according to the read data of each subsystem.

The fan system features are detailed as follows:

intelligent: the fan system also changes the configuration of different dust remover fan systems through parameter setting; the human-computer interfaces of the DCS upper computer are made into unified interfaces, and the physical quantity of the system is selected to be available and not and the range, alarm value and the like are set through parameters; thus, the personnel level and the number required by the early training and construction and the later maintenance can be reduced; the comprehensive result achieves the purposes of saving operation cost, energy conservation and emission reduction.

Digitization: the fan system also comprises a DCS distributed system formed by field buses, so that the anti-interference performance and reliability are improved, the installation and later maintenance cost is reduced, and the purposes of energy conservation and emission reduction are achieved.

And (3) modularization: the fan system field acquisition cabinet ZY100-FC consists of field acquisition modules with different types and network functions; the on-site acquisition module has the characteristics of complete models, multiple functions, convenience in combination, high cost performance and the like; the ZY100-FC is to combine all the acquisition modules together through a bus to acquire or output and control all the physical quantities of the fan system; the modularized combination design enables maintenance personnel to be free of training and after sales, saves the operation and maintenance cost in the later period, and achieves the purposes of energy conservation and emission reduction.

Standardization: because of the specificity of the fan system, the fan system is suitable for the fan control of most bag-type dust collectors, only parameters of different bag-type dust collectors are set differently in software, and an acquisition module with different quantity is added according to a field fan in hardware (because of a bus forming mode, the acquisition module is simple, only a power supply and a network cable are needed to be added), so that unified standardization of the hardware and the software is basically achieved, the cost of early installation and later maintenance is saved, and the purposes of energy conservation and emission reduction are achieved.

The Internet of things: the DCS upper computer set software selected by the fan system has the function of internet of things and only needs to select whether the DCS upper computer set software exists or not; the cost of installation and later maintenance is greatly saved, and the purposes of energy conservation and emission reduction are achieved.

Improvement innovation: a. the traditional PLC centralized control is changed into a DCS centralized and distributed control mode b consisting of configuration software with higher cost performance and an acquisition module, and a high unified standardization c of software and hardware and a fan acquisition cabinet are put on site; the method saves cost for purchasing and constructing the early-stage equipment and maintaining the later-stage equipment, and achieves the purposes of energy conservation and emission reduction.

In summary, the fan system achieves the purposes of energy conservation and emission reduction by means of intellectualization, digitalization, modularization, standardization, internet of things, improvement and innovation and the like, and solves the defects of the current PLC control mode.

FIG. 7 is a block diagram of a side leakage system, which is a DCS distributed control system formed by ZY200-C and ZY100-CC by buses, for measuring dust concentration of each bin and visually detecting whether each bin has cloth bag breakage.

The leak detection system has the following functional characteristics in detail:

intelligent: the number, measuring range, alarm value and the like of the dust concentration meter are set by parameters.

Digitization: the leak detection system is a DCS distributed system formed by field buses.

And (3) modularization: the ZY100-CC is formed by a field acquisition module through a bus, and is the same as a fan system; ZY200-C hardware is the same as ZY200-X and ZY200-QG, and can be interchanged, except that the cure software is different.

Standardization: the leakage detection system is suitable for all bag-type dust collectors.

The Internet of things: the same as the ash removal system.

Improvement innovation: conventional PLC centralized control has not previously had this approach.

In conclusion, the leakage detection system achieves the purposes of energy conservation and emission reduction by means of intellectualization, digitalization, modularization, standardization, internet of things, improvement and innovation and the like, and solves the defects of the current PLC control mode.

The process system mainly transmits network signals to the process system according to the installation position of the bag-type dust collector and the process characteristics of upstream and downstream dust removing points (the process needs to be coordinated and standardized, whether the upstream actively transmits the network signals or the process system is provided with an acquisition module to transmit the network signals), and the process system changes the network signals into uniform format parameters to the upper computer of the fan DCS through the ZY200-G network manager so as to adjust the running state of the fan; and a start-stop subsystem is selected to achieve the purposes of energy conservation and emission reduction. The system is developed mainly aiming at the condition that dust removing points are discontinuous, and the energy saving and emission reduction effects are very obvious; for example, the raw material ore tank dust removing point, the front and rear dust removing points of the blast furnace and the like are required to be started to remove dust best only when the dust is generated, and the high-pressure fan is operated in a power-reducing mode (for frequency conversion) when the dust is not generated, or other subsystems are not operated or are operated in an energy-saving mode, so that the purposes of energy saving and emission reduction are achieved.

The ash removal system is mainly installed and works on site, and is very simple; the dust remover body and the control room only need a power line and a 485 net line. If the pressure difference of the bin is needed, 2 pressure guide pipes are arranged below the clean pressure room and the pattern plate. Compared with the traditional PLC mode, the method has the advantages of installation, design advancement and cost.

On-site operation level: the HQDC100-PS of each bin forms an ash removing system; HQDC100-PS are mutually independent and can work in three working states of manual operation, automatic operation and on-line operation. The dust remover is in an on-line state normally, and the upper computer performs dust removal on the whole dust remover by controlling the HQDC100-PS of each bin through the on-site central control according to the process and parameter setting: the upper computer can work in an automatic state when in fault, and the on-site central control (but HQDC100-PS, PLC or other devices) controls the HQDC100-PS of each bin according to the process and parameter setting to clean the whole dust remover; when the network fails, the system works in a manual state, like a machine side box, and the pulse valve is manually controlled to work in each bin through the HQDC100-PS, and the system is mainly used for overhauling and debugging. The process parameters of HQDC100-PS can be set in all three states.

An ash discharging system is formed by the combination of one or more (related to the number c) HQDC100-DO and HQDC 100-DI; the HQDC100-DO can work in three working states of manual operation, automatic operation and on-line operation. The normal on-line state is realized, and the upper computer is used for carrying out dust discharging control by controlling the start and stop of a vibrator, a dust discharging valve, a scraper, a bucket lifter and the like of each dust bucket through the on-site central control according to the process and the input state of the HQDC 100-DI; the upper computer can work in an automatic state when in fault, and at the moment, the on-site central control (but HQDC100-PS, PLC or other devices) controls the start and stop of a vibrator, an ash discharge valve, a scraper, a bucket lifter and the like of each ash bucket according to the process and the input state of the HQDC100-DI to perform ash discharge control; when the network fails, the machine works in a manual state, like a machine side box, and the vibrator, the ash discharging valve, the scraper, the bucket lifter and the like of each ash bucket are manually operated through HQDC100-DO, and the machine side box is mainly used for overhauling and debugging.

And (3) field central control stage: the device can be HQDC100-PS, PLC or other devices, can work in three working states of manual operation, automatic operation and on-line operation, is normally in an on-line state, and is controlled and data acquired by a main central control on site according to the process and set parameters; when the upper computer fails, the upper computer works in an automatic state, and at the moment, the on-site central control performs control and data acquisition; when in debugging or overhauling, the device can work in a manual state, and at the moment, the on-site pulse valve, the ash discharging valve, the vibrator and other executive devices are manually controlled through the on-site central control. The HQDC100-PS parameters may also be set in the field central control.

Main central control room: the human-computer interface is programmed by various configuration software; under normal condition, the automatic control is carried out by the main central control, and the device has the function of setting the HQDC100-PS parameter, the function of being offline with a lower computer, the function of manually operating each actuating mechanism (such as a pulse valve, an ash discharge valve and the like) on site, the data alarm function and the historical data storage and inquiry function. The coming of the full coverage of the 5G wireless network can display important parameters on the mobile phone according to the requirements of users, so that the production situation can be conveniently known anytime and anywhere, deviation correction is timely carried out, and the production effect is improved.

Ash removal system of large-scale dust remover: a ZY1000-DCS pulse control system is adopted to mainly control the work of an off-line valve and a pulse valve, and ash removal operation is carried out according to set parameters and process requirements.

Ash discharging system of large dust remover: a ZY1000-DCS pulse control system is adopted to mainly control a star discharger, a vibrator, a scraper, a bucket elevator and the like, and ash discharging operation is carried out according to set parameters and process requirements.

Large-scale dust remover fan system: a DCS pulse control system is adopted to mainly control the start and stop of a high-voltage motor control cabinet and collect various process physical quantities of a high-voltage motor and a fan.

Three systems of large-scale dust remover: the ZY1000-DCS pulse control system is adopted, the same configuration upper computer is unified, the control is unified on a human-computer interface, and the ZY1000-DCS pulse control system is independent and does not affect each other.

Design of a large pulse control system in DCS: by analyzing the characteristics of the dust remover process, the control system is integrated and standardized and then integrated into two or three specifications, the system and wiring design are not needed, and all dust removers are universal. The control system solves the problem that the existing PLC centralized control system needs to be customized according to the requirements in each project, namely, a large number of system and wiring designs are needed to be made, and the control systems of different dust collectors in the same project are not compatible.

Manufacturing a large pulse control system in ZY 1000-DCS: unified manufacturing is carried out, no relation to projects exists, the program is loaded and completed before the equipment leaves the factory, and programming and equipment debugging are avoided during installation and use. The problem that equipment purchased by different projects or different manufacturers cannot be interchanged due to the fact that the existing PLC is a centralized control system, necessary components are purchased every time the projects are assembled, and special assembly, massive programming and debugging work are performed is solved.

The large pulse control system in the ZY1000-DCS has strong universality: the operation interfaces of the same series of products are identical, and the operation and maintenance can be called' one-way all. The existing PLC adopts a centralized control system, and the control system and the interface of each device are different, so that the difficulty in user training, use and maintenance is high.

Purchase cost of large pulse control system in ZY 1000-DCS: standard products, more functions and more cost saving. The existing PLC is a centralized control system, and the real price is difficult to estimate due to the existence of a matrix circuit and the goods imitation. The problem that the purchasing cost of the product is high is solved, and meanwhile, the cost of spare parts of the product is easier to control in the production process.

Installation cost of the ZY1000-DCS medium and large pulse control system: the box controllers are connected by buses, the pulse valve controllers are taken as an example, the controllers only need to be arranged beside the dust remover air bags, the control cable of each valve is less than 3 meters long, the length of each valve control cable is far less than the length of each valve control cable which is controlled by the PLC in a centralized manner (calculated by taking the distance from the dust remover to the electric control room as 100 meters, if a centralized operation station is arranged on a plurality of dust removers, the cables are longer), and the construction cost of a large number of cables, materials and cable trench bridges is saved. The existing PLC adopts a centralized control system, all control cables are required to be connected to the top of the dust remover by a PLC cabinet of an electric control room, a plurality of cables are required to be consumed, auxiliary facilities such as a cable trench and a bridge are preset, and the cost is not reflected in quotations of equipment under a plurality of conditions and is borne by a general package party or a business owner in factory design construction. The total cost is high, the construction period is long, the construction amount is large, and uncontrollable factors are many.
