Description

Technical Field

[0001] The present invention relates to the technical field of sludge drying, and particularly to a sludge drying control system. Background Art

[0002] Sludge drying refers to the process of removing most of the water content from sludge through percolation or evaporation. This process is usually carried out in self-evaporation facilities such as sludge drying fields (beds). The main purpose of sludge drying is to reduce the volume and weight of sludge for subsequent treatment and disposal. According to the search results, there are various sludge drying technologies, including natural drying, thermal drying, high-dry dehydration, etc.

[0003] During the process of drying sludge, motor failures may occur due to operational errors or improper maintenance. Since there are a large number of motors, it is necessary for the staff to check each one individually, making the maintenance of drying equipment complex. At the same time, simple control also increases the failure rate of the equipment. Therefore, a sludge drying control system is needed. Summary of the Invention

[0004] The object of the present invention is to provide a sludge drying control system to solve the problems proposed in the above-mentioned background technology. Due to the large number of motors, it is necessary for the staff to perform maintenance one by one, making the maintenance of the drying equipment complicated. At the same time, simple control also increases the failure rate of the equipment. To achieve the above object, the present invention provides the following technical solutions: A sludge drying control system includes a sludge drying treatment PLC control system, an evaporation drying module, a control panel module, an electric control cabinet module, a monitoring module, an indicator light module, and a display instrument module. The sludge drying treatment PLC control system mainly controls the start, stop, speed regulation, and interlock protection of the sludge drying equipment through a preset program. For example, according to the sludge moisture content or temperature parameters feedback by the sensor, it automatically adjusts the hot air circulation rate or the heating medium temperature to ensure the continuous and stable drying process. The main function of the evaporation drying module is to fix the organic matter in the sludge through high temperature or long-term evaporation during the drying process, reduce the microbial activity, avoid the generation of odor and secondary pollution due to corruption, and reduce the mobility of heavy metals through solid phase stabilization, reducing the environmental risk during combustion or landfill. The control panel module is mainly connected to the sludge drying treatment PLC control system through signals, and then the sludge drying steps are operated through the control panel. The electric control cabinet module uses the electric control cabinet in the sludge drying treatment PLC control system as the core control unit, and through the integration of automatic control, parameter monitoring, and equipment protection functions, it ensures the efficient and stable operation of the system. The monitoring module mainly sets thresholds such as temperature overrun and motor overload, triggers audible and visual alarms or remote notifications, and shortens the fault response time to within 30 minutes. The indicator light module mainly helps the staff to check whether the sludge drying treatment PLC control system is working properly during the operation process. The display instrument module mainly helps the staff to check whether there are errors during the sludge drying operation and helps the staff to better dry the sludge.

[0005] Further preferably, the sludge drying treatment PLC control system includes a dry tail gas treatment module. The dry tail gas treatment module converts the water vapor in the tail gas into liquid water through a condenser, recovers the water for sludge conditioning or equipment cooling, realizes the recycling of water resources, and filters the impurities in the tail gas through an activated carbon filter screen.

By installing the control component, during the sludge drying process, the monitoring module inside the PLC control box can monitor each motor in real time, and set values for each motor by using the alarm. When the monitoring module detects that the value of a certain motor exceeds the predetermined value, the alarm will be used to give a prompt, and at the same time, the faulty motor will be displayed through the display instrument screen, so that the staff can quickly understand the location of the fault, which is convenient for quick maintenance. At the same time, the control module can be used to precisely control the equipment, reduce the failure rate of the equipment, ensure the long-term operation of the equipment, ensure the safety and controllability of the whole process of sludge drying, and improve the practicability of the device.
