Complete equipment matched with ammonia synthesis device

Abstract

The invention relates to the technical field of automatic control, in particular to complete equipment matched with a synthetic ammonia device and a control system, which realize multi-system communication and eliminate the adverse effect that a PLC system of the field complete equipment cannot be remotely monitored. The complete equipment comprises a DCS used for realizing multi-system communication and remotely monitoring and controlling PLC control systems of a plurality of devices on site; a coal grinding PLC control system which is used for controlling the coal mill to grind the raw coal and manufacture coal powder and is connected into the DCS control system; a dust removal PLC control system which is used for controlling the bag-type dust remover to absorb pulverized coal generated during raw coal grinding and is connected into the DCS control system; a gas-making PLC control system which is used for controlling the gasification furnace to extract gas required by synthesis of ammonia from the manufactured pulverized coal, and is connected into the DCS control system; and a gas-making PLC control system which is used for controlling the synthetic tower, so that the synthetic tower prepares synthetic ammonia by using the gas extracted from the gasification furnace and is connected into the DCS control system.

Problems solved by technology

[0002] With the continuous development of electronics, software, and automation technology, and the emergence of new application scenarios in the chemical production process, manufacturers of chemical automatic control systems have further developed products with more complete functions, higher software stability, and better operation on the basis of the original system. A convenient new system with an upward compatibility function. Among them, DCS control system is used to prepare synthetic ammonia, some software defects are exposed, the system stability is reduced, and the failure rate of servers, network equipment, and operating computers is also gradually increasing, which brings serious problems to the production system. Certain potential safety hazards. Affected by the delisting of the Microsoft Windows 7 operating system and the shutdown of the DELL T 00 workstation, the available operating computers are gradually decreasing, and it is difficult to meet the production and use requirements. In addition, the complete sets of equipment supporting the ammonia plant, such as the coal grinding system, The dust removal system, etc. are all controlled by PLC system, the system is scattered, and there is no host computer for real-time monitoring equipment, which also brings many unfavorable factors to safe and stable production. Therefore, a new synthetic ammonia device and control system is needed to solve the above problems.
