System for automatically adding and dispensing circulating water scale inhibitor

Abstract

The invention discloses a system for automatically adding and dispensing a circulating water scale inhibitor. The system comprises a scale inhibitor storage system, a scale inhibitor dosing system anda scale inhibitor dosing system, wherein the scale inhibitor storage system comprises a high-level storage tank, a medicine unloading pump and a pipeline, the scale inhibitor dispensing system comprises a scale inhibitor medicine dissolving box, a water inlet electric valve, a medicine inlet pipeline and a medicine inlet electric valve, and the scale inhibitor adding system comprises a metering pump and a valve pipeline. The system is simple in structure, convenient use, controllable and automatic scale inhibitor dispensing and adding are realized; various uncertainty and negligence of manualdispensing are eliminated, the supply quality of the scale inhibitor can be effectively supervised, the stable supply quality is ensured, absufficiency is effectively prevented, stable and controllable scale inhibitor adding is achieved, the circulating water quality can be stabilized, normal operation of a unit heat exchange system is ensured, and the system has very high practical value and popularization value.

Description

technical field [0001] The invention relates to the technical field of scale inhibitors for circulating water, in particular to a system for automatic dosing and dispensing of scale inhibitors for circulating water. Background technique [0002] The dissolving tank is used to dilute the antiscalant stock solution and store the diluted antiscalant at the same time. It is connected to the metering pump fed to the designated tower pool through the outlet pipe at the bottom of the tank. It consists of dilution water pipes and valves, the body of the dissolving tank, outlet pipes and valves, sewage pipes and valves. The metering pump will quantitatively deliver the diluted antiscalant to the designated tower pool. It consists of metering pumps, import and export pipes and valves. The electrical part of the electrical control system is manually controlled on the spot. Manually pass the ladder to lift the 25kg barreled antiscalant stock solution provided by the supplier to the to...

AI Technical Summary

Problems solved by technology

The antiscalant needs 10-15 barrels of 25kg barrels of stock solution each time, which is labor-intensive and has potential safety hazards

The 25kg barreled antiscalant provided by the supplier has a blind spot in the inspection when it enters the factory, and it cannot be 100% guaranteed that each barrel of medicine meets the standards

The proportion of medicines is not precise enough to ensure that the concentration of each dispensing is consistent. Usually, the personnel are lazy and the amount of antiscalant stock solution is not enough or the liquid level of the medicine box is high for dispensing.

There is negligence in manual dispensing, which leads to the phenomenon that the dissolving tank is evacuated and the metering pump is idling

There is a situation where only water is added but no medicine is added, and the circulating water will cause scaling of the condenser under the condition of a high concentration ratio

For related technical problems, no effective solutions have been proposed
