Control Development of Steam Collection System in High Temperature Kitchen of a Ship Based on PLC

In a ship's kitchen, the traditional natural ventilation method is used to directly discharge the waste steam of the steaming rice box, which has the disadvantages of low working efficiency, poor environmental friendliness, large hidden safety risks, and waste of fresh water resources. To this end, by analyzing the working principle of the improved steam collection and processing device, using PLC as the lower computer as the core of the steam collection and processing device control system, and using the touch screen as the upper computer as the man-machine interface, we improved three steaming boxes in a ship's kitchen. The design of the steam collection and processing control system. Finally, through simulation and real ship testing, the results show that the system can effectively collect and process the steam generated by the steamed rice box, which is more efficient, environmentally friendly, safer and safer than traditional natural ventilation. A lot of freshwater resources have practical engineering significance.
