Product Description
Patent for utility model: ZL 2015 2 0057883.X
Enterprise standard number: Q/320706JBC 11-2016.
I,Use:
The hardness of calcium and magnesium compounds in boiler feed water will react chemically or concentrate and crystallize at high temperature to form insoluble scale, which will firmly adhere to the heating surface of boiler. This kind of scale is a bad conductor of heat, which will hinder heat conduction, and in serious cases, boiler tube explosion may occur; In addition, it will aggravate the chemical corrosion of metals under the scale, the harm is quite serious.
Although the condensed water and feed water of the boiler have been softened and desalted strictly, a small amount of calcium and magnesium ions still enter the boiler water. If this part is not treated, scaling will also pose a threat to the safe operation of the boiler.
At present, adding phosphate to boiler water is the most suitable treatment method, and the product (basic calcium phosphate) is a kind of soft water slag, which is easy to be discharged with boiler blowdown and will not adhere to the boiler to become scale.
The dosing device mainly includes four parts: liquid medicine dissolving system, metering dosing system, safety system and control system. Solid phosphate is added into the medicine dissolving box, and then desalted water or condensed water is added in proportion for slow mixing and dissolution, and then added into the boiler drum by the metering pump dosing system.
The dosing control adopts manual mode, and it can also be automatically dosed by follow-up control according to the signal output by the upper system.
II,Classification and structure of dosing device:
The dosing device includes: initial water dosing device, dosing device, boiler water carbonation device, condensate water chlorination device, etc.
Generally divided into: a box of one pump, a box of two pumps, two boxes of three pumps, two boxes of one four pumps.
Composition structure of dosing device: solution tank, liquid level meter, metering tank, agitator, dosing metering pump, safety valve, pressure gauge, control cabinet, valves and pipelines are arranged in a centralized way, and the materials of each component are mainly divided into stainless steel and carbon steel rubber lining.
III,Features of dosing device:
1.The solution tank, metering pump and system pipeline of dosing device are all designed as required, with long service life.
2.It has various control modes such as manual, automatic and manual (automatic) to meet the market requirements to the maximum extent.
3.Regular dispensing and stirring can be realized according to user's requirements.
IV,Instructions for ordering dosing device
1.What kind of chemical solution is provided, and determine the material of dosing device.
2.selected pressure and flow of dosing pump
3.The solution box is generally 1m.
4.Configured as several compartments and pumps.
5.Specifically equipped with: (1) mixer (2) solution tank (3) level gauge (4) safety valve (5) pipeline bracket (6) metering pump
(7) solution tank outlet valve (8) solution tank drain valve (9) water inlet pipeline valve (10) filter (11) dosing pipeline (12) pressure gauge (13)Pump outlet pipeline valve (14) Electric control cabinet (15) Pump inlet and outlet pipeline valves.
V,serviceable range
Boiler water treatment of drum boiler with high pressure and higher parameters.
