Automatic dosing control equipment

Abstract

The invention provides automatic dosing control equipment which comprises a stand, and an electric cabinet, a dosing and blow-off pipeline, a dosing pump and a dosing barrel are respectively arrangedon the stand; the other end of the dosing and blow-off pipeline is connected with a water return pipe of a main pipeline of a circulating cooling water system; the dosing pump and a pollution discharge electric valve are both electrically connected with the electric cabinet and are controlled by the electric cabinet, and a flow meter, a conductivity probe and a corrosion coupon rack are all in signal connection with the electric cabinet. The operation and maintenance cost can be reduced, meanwhile, it is guaranteed that the circulating cooling water system is free of scaling, corrosion and algae growth, and normal operation of the system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cooling circulating water treatment, in particular to automatic dosing control equipment. Background technique [0002] At present, the domestic circulating water system generally uses manual timing and uniform dosing, and the concentration of the medicine in the water is obtained through analysis to adjust the opening of the dosing device. Due to the large volume of the system, analysis hysteresis and analysis frequency are limited, it is difficult to control the concentration of chemicals within a certain range. In order to prevent scaling in the cooling circulating water, scale inhibitors are added to the water body to inhibit corrosion. Antiscalants and fungicides are very necessary. As part of the chemicals are discharged during the sewage discharge process, the remaining concentration of the chemicals is diluted with new water. At this time, scale inhibitors and fungicides must be added to restore t...

Problems solved by technology

Due to the large volume of the system, analysis hysteresis and analysis frequency are limited, it is difficult to control the concentration of chemicals within a certain range. In order to prevent scaling in the cooling circulating water, scale inhibitors are added to the water body to inhibit corrosion. Antiscalants and fungicides are very necessary. As part of the chemicals are discharged during the sewage discharge process, the remaining concentration of the chemicals is diluted with new water. At this time, scale inhibitors and fungicides must be added to restore the water quality balance. Accumulate the amount of replenishment water to carry out empirical calculations. Sufficient corrosion inhibitors, scale inhibitors and fungicides must be supplemented based on the accumulated flow rate as a reference supplement to realize quantitative dosing, so that the scale inhibitors and fungicides in the water body can be supplemented appropriately. This quantification It is more economical to manage more extensive management due to under-quantity, and the loss outweighs the gains. Excessive chemicals increase operating costs, and at the same time increase the secondary pollution of discharged water bodies and the cost of subsequent water treatment.

In addition, there are uncertain changes in the water quality in the system. The laboratory monitoring not only requires a large central laboratory, but also there is a certain uncertainty in the sampling point of the sampling time, which may lead to the certainty of the water quality detection. The determination process is complicated and may cause waste of chemicals and water resources at any time
