Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0040] like figure 1 As shown, the present invention is a high-density clarifier on-line monitoring device. Various detection devices of the device are arranged in each reaction zone of the clarifier and key parts of the clean water zone to realize on-line detection and monitoring of the operating parameters of the clarifier; The operating parameters are compared with the empirical data to guide the operation, adjust and control, and improve the effluent quality of the coagulation and clarification system; the device includes a coagulation zone 1, a flocculation zone 2, a high-density clarification tank separated by concrete from the inlet to the outlet. Push flow area 3, concentration and separation area 4 and clear water area 5; wherein clear water area 5 is located in the upper part of concentration and separation area 4, and the bottom of coagulation area...

The invention discloses an online monitoring device and method for a high-density clarification tank. The device comprises a flow meter and a turbidity meter which are arranged at an inlet of the clarification tank, a sludge concentration meter which is arranged in a flocculation area, a high-definition camera and a pH meter which are arranged in a plug flow area, a high-definition camera which is arranged in a clear water area, a sludge level meter and a sludge concentration meter which are arranged in a concentration and separation area, and a turbidity meter which is arranged at an outlet of the clarification tank. On-line data and information are accessed to a pretreatment on-line monitoring system to guide and adjust the dosage of coagulant, coagulant aid and lime in the clarification tank and the sludge discharge period, so that the effluent turbidity of the clarification tank is stabilized in a standard range. After the device is applied, the problems that the effluent quality cannot reach the standard and fluctuates due to hysteresis, blindness and randomness of operation control of the clarification equipment can be solved, normal operation of subsequent equipment is ensured, the operation economy and stability of the equipment can be greatly improved, and the device has good economic and environmental protection benefits.
Description
technical field [0001] The invention relates to coagulation and clarification equipment for water treatment in thermal power plants, in particular to an on-line monitoring device and method for a high-density clarifier. Background technique [0002] Coagulation and clarification treatment is the first treatment process of the power plant boiler make-up water treatment system. and other substances. At present, coagulation and clarification equipment generally has problems of poor operation effect, poor effluent quality or up to standard but still affecting the normal operation of subsequent equipment, and there is no effective monitoring method. [0003] Most of the domestic thermal power plants are equipped with high-density clarifiers, and most of the clarifiers are currently not operating well. The main reason is that the power plant does not have scientific equipment process parameter detection and monitoring methods, and cannot obtain real-time parameters of the coagul...
