What are the application areas of the boiler dosing device?

The boiler dosing device can be used for the dosing of sewage and waste water treatment in ecological environment protection, the dosing in the furnace of power plants, the dosing of sewage treatment, etc., and the scope is very wide. The following specifically introduces the "application scope and process principle of the boiler dosing device" .

1. The scope of application of the boiler dosing device

1. Sewage and wastewater treatment in ecological environment protection are mainly used for sewage and wastewater treatment in large cities, factories and mines, large and medium-sized hotels, restaurants.

2. Dosing in the furnace of the power plant: adding ammonia to the water supply and drainage, adding hydrazine, adding polyphosphate to the furnace water, centralizing control of adding polyphosphate to the furnace water, and adding ammonia to the condensed water.

3. The heating furnace introduces organic chemical liquid, which is mainly used in places where heating furnaces are applied such as thermal power stations, chemical plants, metallurgical industries, ships, and heating.

4. Sewage treatment and dosing: adding coagulant, coagulant, organic silicon defoamer, etc. to wastewater.

5. It is used for the preparation of drinking water supply and drainage treatment and dosing. The key application sites are large city water companies, well-known enterprises' standby water plants, printing and dyeing, steel, paper industry and other fields.

6. Additional medicine for power plant furnace: source water plus coagulant, source water plus coagulant, cooling circulating water plus thickener (desulfurizer), cooling circulating water plus reverse osmosis scale inhibitor, cooling circulating water plus pesticide Bactericide, adding ammonia between the starting boiler room, adding polyphosphate between the starting boiler room, coating the aluminum sulfate surface of the condenser, etc.

2. Process principle of boiler dosing device

1. The hardness of calcium and magnesium in boiler feed water will chemically react or concentrate and crystallize in high temperature environment, forming insoluble scale, which is firmly attached to the heating surface of the boiler. This kind of scale is a poor conductor of heat, which will hinder heat conduction. In severe cases, a boiler tube burst accident may occur; in addition, it will aggravate the chemical corrosion of the metal under the scale, and the harm is quite serious.

2. Although the boiler condensate and feed water have been strictly softened and desalinated, there is still a small amount of calcium and magnesium entering the boiler water. If this part is not treated, scaling will also threaten the operation of the boiler. At present, adding phosphate to the boiler water is a suitable treatment method. The product (basic calcium phosphate) is a soft slag, which is easy to be discharged with the boiler blowdown, and will not adhere to the boiler and become scale.
