Problems solved by technology

[0003] In the prior art, in order to ensure that phosphate can be added continuously, generally a boiler is equipped with a phosphate dosing box, and every time the phosphate in the phosphate dosing box is used up, the dosing must be suspended until it is added again. Dosing can only be continued after phosphate, not only the dosing process is troublesome, the operation is inconvenient, but also the dosing efficiency is not high, which greatly increases the cost of boiler calcium scale treatment

Abstract

The invention discloses a phosphate dosing device for a boiler. The dosing device comprises a dosing tank and at least two dispensing tanks, wherein a plurality of dosing pipes are connected with thedosing tank; a dosing pump and a dosing flowmeter are arranged on each dosing pipe; a spare pipe is further connected with a position between each dosing pipe and the dosing tank; a spare pump is arranged on the spare pipe; the at least two dispensing tanks are respectively used for containing phosphate and pure water; the dispensing tanks are all communicated with the dosing tank through dispensing pipes; a dispensing pump and a dispensing flowmeter are arranged on each dispensing pipe; and a stirring mechanism and a heating device, which are used for improving the dispensing efficiency, arefurther arranged in the dosing tank. The dosing device is convenient and practical, and high in dosing efficiency, can realize dosing while dispensing, ensures that dosing can be conducted at any time, greatly simplifies the dosing operation, and reduces the cost for treating calcium scale on the boiler.

Description

Technical field [0001] The invention relates to a dosing device, in particular to a boiler phosphate dosing device, and also relates to a dosing method of the above-mentioned boiler phosphate dosing device. Background technique [0002] At present, in order to prevent the generation of calcium scale and alkaline corrosion in the boiler, phosphate is added to the boiler feed water so that the Ca entering the furnace with the boiler feed water 2+ No scale will be formed, but slag will be generated and removed by boiler blowdown. [0003] In the prior art, in order to ensure that phosphate can be continuously added, a boiler is generally equipped with a phosphate dosing tank, and the dosing is suspended every time the phosphate in the phosphate dosing tank is used up. Dosing can be continued after phosphate. Not only the dosing process is troublesome and the operation is inconvenient, but the dosing efficiency is not high, which greatly increases the boiler calcium scale treatment cos...
