Description

The processing method that the burnt slurry of water uses on glass melter

Technical field

The present invention relates to Industrial Stoves fuel and use processing method, specifically relate to the processing method that the water coke slurry fuel uses on glass melter.

Background technology

At present, in the glass manufacturing, generally adopt the calorific value height, the heavy oil that ash is few, coal tar or Sweet natural gas etc. act as a fuel and make glassy product, wherein using maximum is heavy oil, but because fuel sources such as heavy oil, coal tar or Sweet natural gas are in short supply, price is higher again, has a strong impact on glass and makes economic benefit of enterprises.The burnt slurry of water is a kind ofly to have certain fineness, can flow and the stable slurry shape fuel of combustion heat value necessarily through what Physical Processing was made with the byproduct refinery coke with golf calorific value and low ash after the petroleum refining and water and minor amounts of additives, and its price is lower again.Owing to contain the moisture content of larger proportion in the burnt slurry of water, when combustion gasification, need the absorption portion heat, thereby combustion heat value, combustionvelocity and the complete combustibility of the burnt slurry of water are compared low with heavy oil, coal tar or Sweet natural gas etc., it is mainly used at present to the not high station boiler of demanded fuel, ceramic hot-blast furnace, heater for rolling steel etc., because glass melter is higher to specification of quality such as temperature of combustion, ash, therefore, the burnt slurry of water replaces heavy oil, coal tar or Sweet natural gas etc. also not to appear in the newspapers for fuel uses on glass melter always at present.

Summary of the invention

The present invention seeks to have proposed the burnt slurry of a kind of water and on glass melter, use, can not only guarantee the glassy product specification of quality, can reduce the processing method of glassy product manufacturing cost again greatly for fuel.

At first, replace heavy oil to carry out technology and economic feasibility analysis to the burnt slurry of water:

One, water Jiao slurry replacement heavy oil uses on glass melter and carries out technical Analysis, and the burnt slurry of water uses on glass melter, reaches or the approaching same glassy product quality of heavy oil of using, and its technical requirements is:

1, the burnt slurry of water temperature of combustion on glass melter will reach or near flame temperature 1650-1730 ℃ of heavy oil combustion, be analyzed as follows, the heavy oil calorific value is 9500Kcal/kg, the refinery coke calorific value is 8500Kcal/kg, the burnt slurry of the water calorific value that contains 45% refinery coke is 3500Kcal/kg, and promptly the burnt slurry of water that contains 45% refinery coke with 2.71kg can produce the calorific value of suitable 1kg heavy oil; The burnt slurry of the water calorific value that contains 60% refinery coke is 4860Kcal/kg, and promptly the burnt slurry of water that contains 60% refinery coke with 1.96kg can produce the calorific value of suitable 1kg heavy oil; The burnt slurry of the water calorific value that contains 75% refinery coke is 6220Kcal/kg, and promptly the burnt slurry of water that contains 75% refinery coke with 1.53kg can produce the calorific value of suitable 1kg heavy oil.The burnt slurry of the water of calorific values such as burning and heavy oil can reach the flame temperature 1650-1730 of heavy oil in glass melter ℃.

2, refinery coke is the byproduct after the petroleum refining, and contained ash is identical with heavy oil, and therefore, the ash of the burnt slurry of water can not impact glass quality.

3, the burning-point of the burnt slurry of water is 700-800 ℃, and the glasses melting furnace flame space temperature can reach 1650-1730 ℃, and combustion air can reach 800-1520 ℃ through the regenerator preheating, and the burnt slurry of water can be lighted rapidly in the glasses melting furnace flame space and fully burning through atomizing and being injected to.

Two, the burnt slurry of water replaces the comparative analysis of heavy oil use cost as follows: be example to use on 400 tons of/day float glass smelting kiln production lines, see the following form:

Project	The burnt slurry of 45% concentration water	The burnt slurry of 60% concentration water	The burnt slurry of 75% concentration water	Heavy oil

Deng calorific value consumption (kg)	2.71	1.96	1.53	1	Calorific value (Kcal/kg)	3500	4860	6220	9500
Deng calorific value consumption (kg)	2.71	1.96	1.53	1	Annual consumption (ten thousand tons)	7.046	5.096	3.978	2.6
Unit price (unit/ton)	550	700	850	2860	Annual consumption (ten thousand tons)	7.046	5.096	3.978	2.6
Unit price (unit/ton)	550	700	850	2860	Total price (ten thousand yuan)	3875.3	3567.2	3381.3	7436
Save cost (ten thousand yuan)	3560.7	3868.8	4054.7	0	Total price (ten thousand yuan)	3875.3	3567.2	3381.3	7436

By last table analysis, the burnt slurry of water replaces heavy oil to use on glass melter, and its technical and economy all is feasible, and particularly the fuel economy cost is considerable.

The processing method step that the burnt slurry of water of the present invention uses on glass melter is:

Adopting refinery coke content is 45-75%, all the other are the burnt slurry of water of moisture content and additive, after earlier the burnt slurry of water being pressurizeed by mechanical pressurizing device, deliver in the burnt slurry of the water spray gun, and to make the burnt slurry of water be 0.2-1.2MPa in the burnt slurry of water spray gun internal pressure, simultaneously, open air source, air is delivered in the burnt slurry of the water spray gun, and to regulate the pressure of air in the burnt slurry of water spray gun be 0.3-1.5MPa, the burnt slurry of water is fully atomized and be injected in the glasses melting furnace flame space, start gas blower input combustion air, combustion air is sent in the glass melter through the glass melter drum after regenerator is preheated to 800-1520 ℃, and the burnt slurry of water after the atomizing is lighted and fully burning by heating rapidly.

Described mechanical pressurizing device preferably adopts mono-pump, and removes by filter impurity through mechanical stirrer stirring and strainer again, in order to avoid stop up the burnt slurry of water spray gun, the burnt slurry of water is inputed in the burnt slurry of the water spray gun.

The burnt slurry of the water of the described 45-75% of containing refinery coke can be bought on market, and the burnt slurry of water as Guangdong Zhong Shan days second Development Co., Ltds, Datong District's water coal (Jiao) slurry company limited and ceremonial dress for royalty day water coal (Jiao) slurry company limiteds etc. produce also can prepare voluntarily.

If increase the oxygen content in the described air source, its oxygen level is 21%-60%, more helps improving the temperature of combustion of the burnt slurry of water.

The burnt slurry of water of the present invention uses the glass of making on glass melter, product percent of pass all reaches more than 85% after testing, and is identical with the glassy product qualification rate of producing with heavy oil.

The processing method that the burnt slurry of the water that the present invention proposes replaces heavy oil, coal tar or natural gas etc. to use on glass melter; owing to adopt rational water burnt slurry pressure and air atomizing pressure; make the fully atomizing of the burnt slurry of water; and high temperature is combustion-supporting, and the burnt slurry of water sufficient combustion not only can make the glass melter temperature reach 1650-1730 ℃ equally; glassy product conforms to quality requirements; can reduce the glass production manufacturing cost greatly again, save petroleum resources, and help environment protection.
