Automatic dosing device by the conductivity controller as a control instrument dosing system is a circulating water cooling tower dosing is highly targeted automatic dosing system. Fully automatic dosing device to ensure that the circulating water is relatively large dissolved mineral content but does not cause corrosion and scaling, a relatively large extent to save water and chemicals used.
The coagulation process in the water treatment process requires that the amount of drug dosage as much as possible just right, too much or too little on the coagulation effect is unfavorable. Another point to be emphasized, the operating costs of sludge treatment is mainly concentrated in the drug consumption (accounting for more than 90% of the cost). Coagulant automatic dosing device to achieve dynamic and accurate tracking of pharmaceutical dosage needs and automatic adjustment to achieve better coagulation effect and economic treatment, especially important in the coagulation process.
Full-automatic dosing device can automatically according to the technical requirements of water treatment automatic accurate, quantitative dosage of water treatment chemicals, such as: circulating water treatment of scale inhibitors, corrosion inhibitors, disinfection and sterilization agents, water purification treatment of coagulants, coagulants, sewage treatment of nutrients, flocculants, dewatering agents in sludge treatment and so on. Fully automatic dosing device is suitable for various scales of water treatment devices, such as water from hundreds of tons per hour to tens of thousands of tons of circulating water system.
Circulating water dosing is used to treat circulating water treatment system. The fully automatic dosing device has a large filtration area, small size, and is easy to backwash without resistance. It can be widely used in central air-conditioning, heating and water cooling systems as filtration, dosing, removal of scale from pipelines and equipment in the circulating system, regulation of circulating water quality, rust scale and mud scale, and is a practical multi-purpose equipment.
The main items of circulating water treatment: corrosion inhibition and antioxidant to increase the life of system-related equipment and pipelines; scale inhibition, scale prevention, scale removal; adjusting the water quality, so that the circulating water is in a benign state of circulation.
Automatic dosing device of the necessity of circulating water system for about several, central air conditioning, hot water heating and circulating cooling water system, natural water is easy to form scale of harmful calcium, magnesium and silicon dioxide and other substances, due to the innate and acquired control of improper treatment of these ions in the circulating water system after the heat decomposition from the water to form a solid adhering to the pipeline and the heated surface, which not only blocks the pipeline, leading to poor water circulation, but also greatly reduce the water circulation. Resulting in poor water circulation, but also greatly affect the heat transfer of the heated surface of the decline in the circulating water system was impeded, the heavier caused by the system pipeline obstruction, the lighter the decline in work efficiency, so the adjustment of the circulating water, governance, treatment is a very important part.
Two, automatic dosing device working mode:
Start dosing need to start the dosing device within the self-contained liquid lifting pump, with a hose to the liquid from the liquid barrel into the storage tank, lifting the pump has a self-absorption ability, work before the pump body does not need to be filled with liquid. After the storage tank is filled with liquid, the dosage can be adjusted, and after the dosage is adjusted, the dosage can be put into operation.
Acid and alkali (PH) adjustment is to stabilize the PH value of the process media in the required range to meet the needs of the process, in the electroplating process in the plating solution PH control, metallurgical flotation process of slurry PH control, chemical processes in the process media mother liquor PH control. In the water treatment process, the PH value of the treated water will greatly affect the use of a variety of chemicals, different types of wastewater in the completion of a variety of treatment may not be allowed to discharge the PH range.
Full-automatic dosing device using PH controller control of acid and alkali (PH) automatic adjustment system provides a better automatic control program of acid and alkali.
Automatic dosing device is used to dosage chemicals into the water and gas circulation system to improve water quality, prevent scaling, slow down corrosion and remove contamination of the steam quality, thus ensuring the safe operation of the equipment in the water and steam system of the power plant. Categorized by the water and gas cycle process, mainly used in pre-water, water, water, water, circulating water, condensate, ash water and wastewater treatment.
