Abstract
The invention discloses a kind of incinerator coke-removing agent and preparation method thereof, coke-removing agent is made up of the raw material of following parts by weight：30~45 parts of sodium nitrate, 20~30 parts of sodium carbonate, colemanite 12~15,7~12 parts of sodium chloride, 6~10 parts of corundum, 5~8 parts of copper powder, its preparation method comprises the following steps：Copper powder is added in 10 times of copper powder parts by weight dust technologies, sodium nitrate, sodium carbonate, colemanite are added in solution again, solution is heated to 50~60 DEG C, and stirred with stirring rod, solution, which is placed into drying baker, carries out volatilization rewinding, the mixture separated out is collected, mixture adds sodium chloride, corundum, then pulverizes, mixes.Coke-removing agent of the present invention can be simultaneously sprinkled into by the blast orifice and garbage inlet of incinerator, as wind and rubbish are covered at all cokings in burner hearth, and coke-removing agent reacts with coking at high temperature, makes the fluffy softening of dust deposition, it is easy to which come off removing.
Description
Technical field
Technical field is devoked the present invention relates to incinerator, a kind of incinerator coke-removing agent and its system is particularly belonged to
Preparation Method.
Background technology
At present, applied to boiler ash cleaning agent or coke-removing agent it is general mitigated by following four method dust deposition to by
The influence in hot face：1st, ash fusion point temperature is improved using additive；2nd, molten ash is catalyzed with chemical glomerocryst agent, is allowed to from glassy
Melt phase change is into crystalloid；3rd, organize various ash contents to be combined with each other, suppress coking；4th, zone of fracture is formed in slag, and makes dust stratification
Coking nature fragmentation comes off.At present, common ash cleaning agent or coke-removing agent mainly have two major classes：Oxidized form and salt form.The former master
It is nitrate to want composition, and the latter then mainly contains NaCl, Na2CO3Deng alkali metal salt etc..In addition borax, zinc oxide etc. also frequently as
The additive of coke-removing agent.
Waste incineration utilizes and obtains more and more widely paying attention to, but the quality of rubbish is severe, and calorific value is low, and water content is high,
And rubbish inside complicated component, burn produce chemical substance it is also more, it is easier in incinerator produce fouling and slagging show
As.So needing to use suitable coke-removing agent to devoke for incinerator.
The content of the invention
It is an object of the invention to provide a kind of incinerator coke-removing agent and preparation method thereof, prevent and reduce rubbish and burn
The generation of the fouling and slagging in stove is burnt, so as to improve the service life and service efficiency of incinerator.
The technical solution adopted by the present invention is as follows：
A kind of incinerator coke-removing agent, is made up of the raw material of following parts by weight：
Preferably, it is made up of the raw material of following parts by weight：
A kind of preparation method of incinerator coke-removing agent, comprises the following steps：
(1) sodium nitrate, sodium carbonate, colemanite, sodium chloride, corundum, copper powder are weighed according to parts by weight；
(2) copper powder is added in 10 times of copper powder parts by weight dust technologies, reacted 20 minutes；
(3) sodium nitrate, sodium carbonate, colemanite are added in the solution of step (2), solution is heated to 50~60
DEG C, and stirred with stirring rod；
(4) solution for obtaining step (3), which is placed into drying baker, carries out volatilization rewinding, collects the mixture separated out；
(5) mixture for collecting step (4) adds sodium chloride, corundum, then pulverizes, mixes, and crosses 60 eye mesh screens and collects
Mixed-powder, is finally placed on 150~180 DEG C of forced air dryings in baking oven by mixed-powder.
A kind of incinerator coke-removing agent of the present invention, is made up of the raw material of following parts by weight：
30~45 parts of sodium nitrate；20~30 parts of sodium carbonate；
Colemanite 12~15；7~12 parts of sodium chloride；
6~10 parts of corundum；5~8 parts of copper powder, its action principle is as follows：
Sodium nitrate is the main component of oxidized form ash cleaning agent, and incinerator dust stratification belongs to the strong high temperature sintering of caking property
Ash, and oxidized form ash cleaning agent has better effects for removing this type dust stratification.Therefore, it is clear using sodium nitrate as incinerator
The main component of grey agent.
Sodium carbonate enables to dystectic silica and alumino-silicate to melt, and reaction product easily departs from coking body
And come off, and drain with flue gas.
Colemanite decomposes generation boric acid, boric acid and sulfuric acid reactant salt in coking at high temperature, makes the reduction of coking viscosity, easily
In coming off.
With sulfate purification reaction occurs for sodium chloride, generates sodium sulphate, reduces slagging scorification viscosity, is easily peeled off.
Corundum dilatancy is high, and corundum expansion makes slagging scorification be cracked under high temperature.
Copper and dilute nitric acid reaction, reduce slag viscosity.
Compared with the prior art, beneficial effects of the present invention are as follows：
The coke-removing agent of the present invention can be simultaneously sprinkled into by the blast orifice and garbage inlet of incinerator, with wind and rubbish
Cover at all cokings in burner hearth, coke-removing agent reacts with coking at high temperature, makes the fluffy softening of dust deposition, it is easy to come off
Remove.
