First mud enter mud and receive storehouse, is sent to diluting modification pond and carries out dilution stirring, then rise to storage basin through spiral flood dragon; Storage basin carries out stirring to mud and prevents it from precipitating, and in diluting modification pond and storage basin, carry out modification by lime, iron trichloride to mud, the mud in storage basin adds to sludge filter press through high pressure screw pump; Sludge filter press dewaters to mud, dry, concentrated, be finally made into dry mud and transport burning;
Concentration Testing, Level Detection is had in diluting modification pond; Concentration Testing information is sent in the main PLC of Central Control Room and contrasts, and determines whether thin up; Add water and to be performed by conduit pipe pneumatically valve, after liquid level reaches predeterminated position, the main PLC of Central Control Room, to pneumavalve signal, stops thin up, opens agitator motor simultaneously;
In storage basin, control liquid level by liquid level detection device, equally Detection Information is delivered in the main PLC of Central Control Room, provides signal by the main PLC of Central Control Room, open and stir; And in this link, detect the chemical property of mud, and carry out modification by iron trichloride and lime; Addition is different as required, detects flow, fed back to by addition in the main PLC of Central Control Room and go by the magnetic flow meter adding pipeline;
After the process of sludge chemical characteristic completes, added to sludge filter press by high-pressure spiral bar pump; The steps such as squeezing water tank adds water to pressure filter, and mud carries out squeezing in sludge filter press, dewater, dry, concentrated, are finally made into dry mud; Sludge filter press has independent PLC control program, carries out communication link, instructed the execution of sludge filter press by Central Control Room by exchange board and the main PLC of Central Control Room.
This sludge treating system comprises control and Non-follow control two schemes automatically; Under automatic control state, position, whole reference mark can perform by crawl, also can link and automatically perform, specifically at Central Control Room industry control hands-operation, industrial computer have technical process picture, watch-dog executing state and all kinds of warning; Under Non-follow control state, each reference mark controls separately, is independent of each other.
The equipment controlled comprises: mud receives storehouse, spiral flood dragon, diluting modification pond sludge stirring device, sewage sludge storage pond whipping appts, diluting modification pond sludge lifting pump, iron trichloride dosing system, sludge filter press, the water pump that washes cloth, all kinds of automatic control pneumavalve and the frequency converter controller that motor is performed; Test set comprises: liquid level sensor, PH sensor, pressure transmitter, concentration detection sensor, magnetic flow meter, hot resistance etc.
The invention has the beneficial effects as follows:
Based on the sludge treating system that PLC controls, compare original old technique and electric control system, have obvious superiority.The automatic business processing treatment stage that new control system can realizing each in technique, and by the reliability of PLC control technology, more thorough to the process of mud, the dry mud environmental pollution of generation is less; In original workshop, level of automation is low, and some equipment needs human assistance to complete.Workshop stench causes certain injury to human body.And this new technology of preparing can realize workshop Unmanned operation, and there is special deodoration system, well improve Working environment and save manpower.No matter this economically or Working environment aspect, is obtained for good evaluation.
Accompanying drawing explanation
Fig. 1 is system schematic of the present invention.
