Embodiment 1

[0041] Apply the medicament of 10% concentration, and described medicament composition ratio is:

[0042] Polymaleic anhydride 30%;

[0043] Polyepoxysuccinic anhydride 30%;

[0044] Organic ammonia 20%;

[0045] Benzene compound 10%;

[0046] Water 10%.

[0047] Carry out 5 experiments, measure SiO in furnace water, superheated steam, saturated steam 2 The content and pH value are respectively:

[0048]

Embodiment 2

[0050] Apply the medicament of 15% concentration, and described medicament composition ratio is:

[0051] Polymaleic anhydride 10%;

[0052] Polyepoxysuccinic anhydride 10%;

[0053] Organic ammonia 30%;

[0054] Benzene compound 30%;

[0055] Water 20%.

[0056] Carry out 5 experiments, measure SiO in furnace water, superheated steam, saturated steam 2 The content and pH value are respectively:

[0057]

[0058] It can be seen that the data measured in the two examples have played the role of increasing the pH value of condensed water, reducing air bubble entrainment, enhancing steam quality and reducing boiler blowdown rate.

Abstract

The invention discloses a non-phosphorus sodium-free boiler water treatment agent which consists of polymaleic anhydride, poly-epoxy succinic anhydride, organic aminos, a benzo compound and water. The non-phosphorus sodium-free boiler water treatment agent is a multifunctional non-phosphorus sodium-free boiler treatment agent consisting of full organic polymers, efficient dispersing agents, aids and the like. Through reaction described in the specification, hard scale in boiler water can be chelated and dispersed, scaling can be prevented, potential corrosion caused by deposition of iron, copper and the like in a main boiler tube can be prevented, moreover, the pH value of the boiler water is stabilized, corrosion of pipelines and valves can be reduced, sodium phosphate can be substantially replaced, mingling can be avoided, and steam quality can be improved. The critical salt content of a boiler can be increased, concentration of the boiler water can be facilitated, and the energy can be saved.

Description

technical field [0001] The invention relates to a boiler water treatment agent, in particular to a boiler water treatment agent. Background technique [0002] Furnace water refers to the water flowing in the boiler body system, which is usually purified water, but the water still contains dissolved oxygen, chloride ion, calcium ion, magnesium ion, silica, conductivity and alkalinity and other soluble solidification things. The furnace water is continuously evaporated and concentrated, and part of it is brought out with the steam and deposited in the equipment such as steam turbine and air compressor, causing salt accumulation in the equipment; part of it stays in the furnace and forms scale after chemical reaction. Under normal circumstances, it is necessary to add medicaments and solve the problem through fixed and continuous rows. [0003] General boiler water agents (high pressure and below boilers) mainly include phosphate and coordination PH-phosphate. Phosphate and ...
