Abstract
The invention relates to a glass processing auxiliary process, in particular to a process using petroleum coke for modified synthesis of carbon powder as float glass furnace fuel. The process includes: enabling petroleum coke powder to enter a power flow generator from a powder storage bin prior to being mixed with delivered gas, delivering power flow to a delivery pipe network, enabling powder in the delivery pipe network to enter a burner through a distributor and a flow regulator, and arranging a control valve between the burner and a furnace hearth. The modified synthesized carbon powder is mainly made of the petroleum coke and achieves modification after fine grinding and a certain process treatment. The carbon powder has the advantages of good flowability, stable performance, low moisture, high expansibility, easiness to light, high burnout ratio, no sparks and the like and is suitable for burning of industrial fuel oil furnaces such as float glass furnaces, horse shoe flame furnaces and industrial furnaces.
Description
Technical field
The present invention relates to the attached technology of a kind of glass processing, specifically relate to a kind of with the technology of the synthetic carbon dust of refinery coke modification as float glass smelting kiln fuel.
Background technology
The main fuel that glass industry uses is heavy oil, oil fuel, Sweet natural gas etc., because in recent years, petroleum resources were gradually nervous, and international oil price is constantly high, and domestic heavy oil substantial appreciation of prices causes the glass industry fuel price constantly to rise.In nearly two years, the heavy oil price has been turned over some, causes the enterprise production cost constantly to raise, and has a strong impact on the business activities of enterprise.Actively seek substitute energy, to reduce fuel cost imperative.
Summary of the invention
In order to solve the technical problem that exists in the prior art; The object of the present invention is to provide and a kind ofly compare with using heavy oil; The glassy product of producing is identical in quality, and the fuel economy cost synthesizes the technology of carbon dust as float glass smelting kiln fuel with the refinery coke modification 20% or more.
The technical scheme that the present invention adopts is following:
With the technology of the synthetic carbon dust of refinery coke modification as float glass smelting kiln fuel; It is characterized in that; After the refinery coke powder enters into powder stream maker and delivering gas mixes by powder-storage bin; Powder stream is sent to transmission pipeline network, and powder gets into burner through divider, regulator in the transmission pipeline network, is provided with by-pass valve control between burner and the melting furnaces burner hearth.
The synthetic carbon dust of modification as main raw, after fine grinding and certain process processing, reaches the modification purpose by refinery coke.It has good fluidity, stable performance, and moisture is low, and very big swelling property is prone to light and the burnout rate height, does not produce characteristics such as Mars, is suitable for float glass furnace, the burning of fuel oil Industrial Stoves such as horseshoe flame furnace and worker's kiln.
Prove through industrial application, the synthetic carbon dust of modification can replace fully that glass industry uses traditional fuel---heavy oil, oil fuel, Sweet natural gas etc. have remarkable economic efficiency and social benefit.The successful development of the synthetic carbon dust of modification has been developed a kind of brand-new fuel for glass industry, is the revolution of glass furnace fuel technology, has development prospect difficult to the appraisal.
In sum; This project is to be the novel energy-conserving fuel of main material production with the refinery coke; Ability deep development utilization " three wastes " goods and materials refinery coke; Improve added value, meet " National Development and Reform Commission is about printing and distributing the notice of Eleventh Five-Year Plan comprehensive utilization of resources instruction " and " Eleventh Five-Year Plan ten big emphasis energy conservation project implementation guidelines " and close the policy spirit that substitutes petroleum engineering about saving.Refinery coke excludes the national energy sequence as the petrochemical industry end prod, and using refinery coke to be used for the energy is to disregard energy consumption, and production of units total value GDP energy consumption descends 100%.Popularize the synthetic carbon dust of modification in an all-round way and replace heavy oil to be applied to glass production, can significantly reduce glass and make fuel cost, promote enterprise competitiveness.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a process flow diagram of the present invention.
Embodiment
See also Fig. 1; After the synthetic carbon dust of modification enters into the stokehold powder-storage bin, generate the homogeneous powder stream of certain gas-solid ratio, in burner, spray after entering into the divider current-sharing through e Foerderanlage and pipeline through powder stream maker; Continuous burning in burner hearth is to satisfy the process of glass requirement.
This system is by powder-storage bin (storage tank in the diagram), weighing device, powder maker, powder stream transferpump, powder stream under meter, maker gear, computer control system, atomising burner, compositions such as powder fluidic distributor.
Powder-storage bin is made up of powder storehouse body, dust-precipitator, strainer, powder inlet pipe road, fluidizer, weighing device, charge level controller etc.The synthetic carbon dust storage capacity design of modification is greater than 100 tons, and the warehouse entry powder can be designed to pipeline conveying or two kinds of modes of tank car conveying according to owner's field condition.
Powder stream generation system is made up of powder flow-generator, weighing device, fluidizer, pressure control device, powder stream handling machinery, safety-valve, computer control system etc.After powder entered into powder stream maker and delivering gas mixes by a certain percentage by powder-storage bin, the flow control value that provides according to computingmachine was sent to pipe network with powder stream.Each port will must carry out the powder flow set by needs according to process value, to satisfy the processing requirement of different ports.
The stokehold firing system flows transmission pipeline network, powder fluidic distributor, connection flexible pipe, burner, by-pass valve control etc. by powder and forms.
The present invention arranges as the firing system of the technology of float glass smelting kiln fuel with the synthetic carbon dust of refinery coke modification:
1) the synthetic carbon dust firing system of modification is taked only arrangement, and system is made up of burner three parts under system master equipment, transmission pipeline network, the stove.
2) main control equipment is installed and is adopted steelwork, can shorten fabrication cycle greatly like this.Main control equipment is arranged in the melting furnaces factory building outside, and particular location should be confirmed according to owner's field condition.
3) system's major equipment comprises: equipment and annexes such as storage powder jar, powder stream maker, powder stream handling machinery, gas-holder, by-pass valve control, pipeline and electrical instrument; Can fully satisfy the fuel of float glass process kiln thermal technology needs and carry control, the control of powder stream flow and flow velocity can reach the fuel engineering requirement.
4) transmission pipeline network is the connecting pipeline between burner under master control equipment and the stove, is responsible for the conveying of qualified powder stream.Every port is furnished with one road transport pipe, and each pipeline is arranged in parallel on the carriage.
