Control system for soft sludge body granulation and drying equipment

Abstract

The invention discloses a control system for soft sludge body granulation and drying equipment, which comprises a granulating machine, a drying machine, a cabin, a ventilator and a conveyor, and is characterized by further comprising a PLC (Programmable Logic Controller), a safety control assembly, a human-computer interface touch screen, a remote control terminal and UV photolysis, wherein the PLC is electrically connected with temperature sensors, gas concentration sensors, a humidity sensor, a pressure sensor and a level indicator in the components, the safety control assembly and the UV photolysis, the PLC is electrically connected with the human-computer interface touch screen through the RS485, and the PLC is electrically connected with the remote control terminal through the Ethernet. The control system realizes real-time monitoring for the gas through fixedly installing the gas concentration sensors at the upper and lower end parts of the granulating machine. Meanwhile, a gas alarm value is set on the touch screen, and a real-time monitored gas value is compared with the initially set gas alarm value through the PLC system so as to realize the alarm work for the gas.

Description

Technical field [0001] The invention relates to the technical field of granulation and drying equipment, in particular to a control system for sludge soft granulation and drying equipment. Background technique [0002] With the continuous improvement of the level of urbanization in my country, the construction of sewage treatment facilities has been rapidly developed. There are more than 2500 urban sewage treatment plants in my country, and the urban sewage treatment capacity has reached 122 million tons per day. The environment has improved and made a huge contribution. However, the construction and operation of sewage treatment plants have accompanied a large amount of surplus sludge. With a moisture content of 80%, the total annual sludge water production in the country will soon exceed 30 million tons, and the sludge treatment situation is very severe. [0003] In order to reduce the amount of sludge, sludge drying equipment is used to dry the sludge to achieve the purpose of r...

AI Technical Summary

Problems solved by technology

In the actual use process, due to the different understanding of the performance of the drying equipment by the workers and the level of the workers' operation level, the normal operation of the equipment will be affected. At the same time, a large number of manual interventions will increase the operating costs of the enterprise.
