Problems solved by technology
Therefore, the system consumes a lot of electric power, does not save energy, and there is a phenomenon that the actual opening of the flue gas damper baffle does not coincide with the PLC control system of the damper actuator, resulting in excessive exhaust or failure to discharge the flue gas in time
Excessive discharge of flue gas will increase the negative pressure of the furnace, reduce the heat storage capacity, and increase energy consumption; on the contrary, the flue gas cannot be discharged in time, resulting in a decrease in the negative pressure of the furnace, a decrease in the oxygen content of the furnace, a decrease in combustion efficiency, and easy formation of Harmful gas, and it is easy to trigger the furnace flame alarm, causing system failure

The invention discloses an intelligent frequency conversion marine incinerator control system. The intelligent frequency conversion marine incinerator control system comprises a marine incinerator body. The marine incinerator body is provided with an electric cabinet and a mechanical pressure type combustor. The mechanical pressure type combustor is connected with a diesel oil cabinet. The intelligent frequency conversion marine incinerator control system further comprises a sludge oil cabinet connected with the marine incinerator body. The electric cabinet is provided with a PLC control system used for controlling the device. The frequency conversion technology is utilized, frequency conversion control is conducted over a high-temperature flue gas draught fan in a marine incinerator system, the motor speed of the flue gas draught fan is automatically adjusted according to the operating condition requirements of the system in combination with the monitored hearth temperature, the monitored flue gas temperature and the monitored hearth negative pressure, and therefore the draught fan is adjusted according to the requirements of the draught fan exhaust amount needed for a set program; and the electric power consumption of the draught fan can be greatly reduced, and the purpose of energy saving during system operation is achieved. Meanwhile, in the system, a flue gas air door in a traditional marine incinerator system is omitted, the occupied space requirements of the flue gas air door installed in a cabin are lowered, and flue gas pipelines are simplified.
Description
technical field [0001] The present invention relates to an intelligent frequency conversion marine incinerator control system, in particular to a marine incinerator control system that can be used to incinerate solid and liquid ship waste such as food, domestic waste, and sewage oil, and belongs to ship building technology, incineration technology and Automatic control technology field. Background technique [0002] According to the applicant's knowledge, due to the current situation of high mobility, long cycle and short docking time of ships, a large amount of ship waste is difficult to deal with. If these wastes are not handled properly and thrown into the sea, it will not only pollute the sea water quality, but also destroy the habitat of animals and plants in the sea, seriously affecting the ecological balance of the sea. In addition, if it is placed and waited for disposal at the port, it will occupy the space in the cabin, and food wastes are not easy to store, which...
