Abstract
A liquid coke-removing agent for the boiler using coal as fuel is proportionally prepared from triethanolamine, sodium laurylphenyl sulfonate, polyoxyethene, polyoxyviny ether, T:Cl3, cerium nitrate, nickel sulfate and water.
Description
Technical field:
The present invention relates to a kind of technology, be used for the decoking agent of coal firing boiler specifically with the chemical solution cleans boiler inner wall.
Background technology:
The burner hearth coking has very big influence to safety, economical operation and the reliability of boiler.Present domestic boiler clinker removal method, the main use removed ashes and deashing powder; These methods generally are difficult to remove fully to coking in the stove, and the decoking rate is low.
Summary of the invention
The purpose of this invention is to provide the effective liquid decoking agent of a kind of decoking.
Decoking agent of the present invention, be to be made by the raw material of following weight percentage: trolamine, Sodium dodecylbenzene sulfonate, three kinds of compositions of polyoxyethylene account for 8-16% altogether, preferred 10-13%, wherein trolamine: Sodium dodecylbenzene sulfonate: polyoxyethylene=1: 1: 1; Soxylat A 25-7 accounts for 5-20%, preferred 10-15%; Titanous chloride, cerous nitrate, three kinds of compositions of single nickel salt account for 7-14% altogether, preferred 10-12%, wherein titanous chloride: cerous nitrate: single nickel salt=1: 1: 1; Water accounts for 50-80%, preferred 60-70%.
Decoking agent of the present invention is in coal-powder boiler test time more than 2 years of 75t/h, in use, decoking agent is used the coal-powder boiler injection system, decoking agent is sprayed into the combustion zone, make decoking agent be full of whole furnace cavity, fully contact with the black dirt and the close-burning thing of all sites in the burner hearth, remove the black dirt and the close-burning thing of every nook and cranny.The black dirt of burner hearth and boiler bottom and close-burning thing are removed, and decoking is remarkable, have loseed the close-burning thing during range estimation.Facts have proved that liquid decoking agent of the present invention not only can be removed old close-burning thing and black dirt, can also prevent the new close-burning thing and the formation of black dirt, and boiler is played maintenance action, has improved the thermo-efficiency of boiler greatly.Liquid decoking agent of the present invention belongs to neutral, and is nontoxic, non-volatile, do not explode, do not pollute, do not corrode boiler, is convenient to safe handling.
Embodiment
The following examples can make those skilled in the art more fully understand the present invention, but do not limit the present invention in any way.
The proportioning of decoking agent of the present invention when mixing use with water and coal is:
Decoking agent: water: coal=1: 1500-2500: 15000-25000
Following examples are standard with the double centner decoking agent all:
Embodiment 1
Get 2.667 kilograms of trolamines, 2.667 kilograms of Sodium dodecylbenzene sulfonatees, 2.666 kilograms of polyoxyethylene, 20 kilograms of Soxylat A 25-7s, 4.667 kilograms of titanous chlorides, 4.667 kilograms of single nickel salts, 4.666 kilograms of cerous nitrates, 58 kilograms in water is mixed and made into decoking agent.
After then 1 kilogram of decoking agent being diluted with 1.5 tons of water, spray into the combustion zone, be used for 15 tons of fire coals with injection system.
Embodiment 2:
Get 5.333 kilograms of trolamines, 5.333 kilograms of Sodium dodecylbenzene sulfonatees, 5.334 kilograms of polyoxyethylene, 5 kilograms of Soxylat A 25-7s, 2.333 kilograms of titanous chlorides, 2.333 kilograms of single nickel salts, 2.334 kilograms of cerous nitrates, 72 kilograms in water is mixed and made into decoking agent.
After then 1 kilogram of decoking agent being released with 2.5 tons of water alkene, spray into the combustion zone, be used for 25 tons of fire coals with injection system.
Embodiment 3:
Get 4 kilograms of trolamines, 4 kilograms of polyoxyethylene, 4 kilograms of Sodium dodecylbenzene sulfonatees, Soxylat A 25-7 are 13 kilograms, 3.667 kilograms of titanous chlorides, 3.667 kilograms of single nickel salts, 3.666 kilograms of cerous nitrates, 64 kilograms in water is mixed and made into decoking agent.
After then 1 kilogram of decoking agent being diluted with 2 tons of water, spray into the combustion zone, be used for 20 tons of fire coals with injection system.
Decoking agent of the present invention is mainly used in black dirt and the close-burning thing that produces when removing the coal-powder boiler fire coal, improves the thermo-efficiency of boiler, during use, does not stop boiler and normally moves, and ensures safety in production.
