Stainless steel automatic dosing device, stainless steel automatic dosing device, including automatic or manual, large volume measuring box or small volume measuring box, single box or double box, single pump, two pumps or three pumps and different materials constitute a series of products. In the environmental engineering, water treatment and production process systems in the fields of electricity, chemicals, petroleum, food, beverage, pharmaceutical and other fields, it is often necessary to continuously add a certain dosage of the agent in the process in order to meet the production requirements. The best way to prescribe this is mostly through automatic metering devices. Combined automatic metering device is a combination of liquid metering tank, dosing pump, automatic control system, connecting piping and other complete sets of equipment.

Application and principle

The addition of 1 to 5% ammonia solution (about 1 to 2 μg / L) to the feed water (or condensate) system by adding water to the feed water (or condensate) system. ) And free carbonic acid, to improve the PH value of water to the specified range (8.5 to 9.3) to reduce the low pH value of carbonic acid and oxygen caused by corrosion. (20 to 50 μg / L) of the compound (0.1 to 0.3%) is chemically deoxygenated and the reduction of the furnace water is maintained to prevent oxygen corrosion and the furnace Deposition of metal oxides.

The circulating cooling water is added to the water quality stabilizer or the measurement of sulfuric acid, adding acid to the replenishment water of the circulating water system to reduce the alkalinity, converting the carbonate hardness in the supplementary water into non-carbonate hardness, controlling the circulating water after the concentrated carbon Acid salt hardness below the limit, in order to achieve the purpose of anti-scaling. Plus stabilizer to improve the limit of circulating water limit carbonate to prevent calcium carbonate scaling, and to avoid the simple addition of acid to sulfate to produce calcium sulfate scale. Some stabilizers and both corrosion inhibition.

Boiler water plus phosphate (low-parameter boiler to eliminate residual hardness in feed water, high-parameter boiler to adjust the furnace water PH) measurement.

In the pretreatment system, the fungicides, coagulants, reducing agents and pH adjusting agents are added to eliminate the microorganisms, organic matter, suspended solids and colloids in the raw water, oxidants in the water, excessive acidity and alkalinity in the water, To ensure the need for deep processing of make-up water.

Chemical cleaning process to the cleaning solution, passivation solution by adding cleaning agents, corrosion inhibitors, solvent and passivation agent of the liquid metering.

Water treatment and wastewater treatment Dosing and ion exchange process.

Dosing device use

, The dosing system is a complete set of equipment with dosing, stirring, liquid conveying and automatic control. It is widely used in the raw water of the power plant, the boiler feed water, the oil field ground collecting and disinfecting system, the petrochemical dosing system And wastewater treatment systems. Such as dosing coagulant, phosphate, ammonia, lime water, corrosion inhibitor, scale inhibitor, sterilization algae, etc.

Automatic dosing device Scope: water treatment in the addition of coagulants, filter aid, disinfectant, acid and alkali.
Cooling water, circulating water plus a scale inhibitor.
Chemical, printing and dyeing, adding acid, alkali solution and other solutions.

Dosing device selection Note:

(Name, concentration, temperature, density, density, density, density, density, density, density, density, and density) of the dosing device (stainless steel, carbon steel, nonmetallic material), metering pump model (diaphragm pump, plunger pump) or to our company , Viscosity, corrosion, etc.).

The user chooses the dosing device, first according to the system needs to add the amount of solution to determine the selected specifications (including metering pump parameters, the tank volume and other conditions), and then according to the situation, to determine the dosing method (generally use " "The way).

Dosing system main features:

① centralized design, covers an area of ​​small, simple structure, stable performance; ② accurate measurement, easy adjustment, good economy, easy to install and maintain;

③ pump for the inhalation installation, not easy to plug, trouble-free running a long time, low operating costs; ④ excellent corrosion resistance, long service life.

⑤ solution box material: PE, glass steel, carbon steel lined rubber, 304 stainless steel, 316 stainless steel; ⑥ blender material; 304 stainless steel, 316 stainless steel;

⑦ metering pump overcurrent part of the material: PP, PVC, PVDE, SS316;
