Smarter! Airiot accelerates the upgrading of energy conservation and emission reduction in the coal industry

“ Double carbon policy ” Next , All industries are practicing energy conservation and emission reduction , Rely on digitalization 、 Intelligent means to carry out energy conservation and emission reduction . The coal industry is a major energy consumer , Coal washing is one of the important links of energy conservation and emission reduction in the coal industry , Strengthen the clean and efficient utilization of coal , It is particularly important to do a good job in coal washing at the source of clean coal . As a matter of fact , Most coal preparation plants are intelligent 、 The level of automation construction and informatization is low , Still in the exploratory stage , There is still a long way to go before the realization of comprehensive digital management .

Coal washing refers to the separation of raw coal into clean coal through coal washing 、 Medium coal and gangue , Improve the utilization efficiency of coal . The technological process is generally prepared before selection 、 The raw coal is sorted after crushing and screening 、 The product is composed of graded dehydration and slime treatment . The dense medium coal preparation process also includes medium recovery 、 Purification operation .

In the coal preparation production system , The intelligent application of washing machines and equipment is the core to speed up the technological transformation of coal preparation plant . For dense medium density of coal preparation plant 、 jigging separation 、 Flotation and dosing 、 Coarse slime separation 、 Concentration system and dosing 、 Settlement treatment 、 Loading coal blending system 、 Drying system 、 A series of complex process equipment such as filter press cluster are in the majority , The problem of fewer post personnel , How to establish and improve strict and accurate requirements for equipment maintenance and single operation through digital technology , It has become an urgent problem to be solved in the current coal preparation plant .

In order to realize the functional interconnection between the production and operation of the coal preparation plant and the equipment management , Information sharing , Real time monitoring of process equipment status, etc ,AIRIOT The platform adopts low code construction technology to establish process centralized control system and automatic dosing system for the coal preparation plant , The process remote monitoring is realized 、 Data collection 、 Equipment management monitoring 、 Production visualization 、 Mobile management and other functions , Comprehensively improve the information intelligence level of the coal preparation plant , The efficiency of production scheduling collaboration is improved , Reduce equipment failure rate and production and maintenance costs , The operation efficiency of the coal preparation plant has been significantly improved .

One 、 Unified technology architecture Intelligent centralized control system

Design based on microservice architecture ,AIRIOT The platform develops an intelligent centralized control system with unified technical architecture , It realizes the real-time monitoring between operating systems 、 Control automation 、 Management informatization 、 Business flow automation 、 The goal of intelligent decision-making , The data fusion, sharing and unified coordinated management and control of the coal preparation plant are realized .

In the centralized control system of the coal preparation plant ,AIRIOT The visual configuration engine plays a decision-making role , More than 100 sets of equipment are in “ Spontaneous ” Running at high speed , From raw coal screening to flotation dosing 、 From coal slime floating to product loading, etc , The production process of each link is in the visual monitoring center LED You can see everything on the screen . Realize the whole process and dynamic coal quality control , The qualified rate of clean coal reaches the highest peak .

 

AIRIOT Automatic dosing system

Coal preparation plants usually add flocculants in the process of slime water concentration and clarification to accelerate the settling speed of slime , Improve the thickening and clarification effect of coal slime , Thus reducing the washing concentration . Join in PAC（ Polyaluminium chloride ） And PAM（ polyacrylamide ） Prepare as an aqueous solution , To improve the solid-liquid separation efficiency of the concentration tank , To reduce the overflow concentration of the concentration tank .

Due to the , The medicament is added at one time , And the water quality will be affected no matter the dosage, dosing time interval and water consumption ：

1. The medicament is not accurate 、 uniform 、 Add in time , The concentration of the prepared aqueous solution is unstable .
2. because PAC And PAM It is a solid powder , Slow dissolution in water , If the mixing speed is slow and the force is small after entering the water , The two drugs cannot be fully dispersed , So that part of the medicament can not be effectively dissolved .

The addition of medicament will also have a certain impact on the use effect of flocculant , How to realize the concentration proportioning of automatic dosing proportioning device ,AIRIOT The built automatic dosing system provides a perfect solution for enterprises .

AIRIOT The data acquisition and control engine monitors the inlet and outlet water quality parameters , The enterprise can match the dosage through system parameters ,AIRIOT The automatic dosing system can also intelligently calculate the dosing proportion according to the water quality parameters , Distribute to the platform , The enterprise can match the dosage according to the parameters issued by the system , Achieve precise dosing .

Equipment status monitoring

Coal preparation plant mechanization 、 The degree of automation is constantly improving , The equipment has become the production and operation of coal preparation plant 、 Create benefits 、 Important assets to improve market competitiveness , This undoubtedly brings new challenges to the equipment management of coal preparation plant . Coal preparation plant equipment is the material and technical basis of production activities , Its performance is directly related to the separation effect 、 The size of the production capacity 、 Technical level of bump 、 The amount of energy consumption and the economic benefits of the coal preparation plant . Therefore, it is more and more important to properly manage the coal preparation equipment .

To ensure the normal operation of coal preparation equipment , Maximize the production efficiency of electromechanical equipment , To standardize the management of electromechanical equipment ,AIRIOT The built equipment state system realizes the production process equipment 、 Auxiliary equipment 、 Electrical equipment 、 Equipment for experimental research 、 Management equipment and other real-time monitoring functions , Manage and monitor the best condition of the whole life process of the equipment , And make decisions and suggestions on maintenance strategies according to the health characteristics of the equipment , So as to realize the healthy and intelligent management of all station equipment in coal preparation plant .
