Description
Technical field
The utility model relates to a kind of New Regenerative burner that is used for the industrial furnace heating, particularly relate to a kind of line pulse winding-up decontamination apparatus that has, use the New Regenerative burner that carries out online scrubbing of sphere and honeycombed heat storage at industrial heating furnace.
Background technology
Nineteen eighty-two, the Hot Work and the company of Centrica (British Gas) of Britain cooperated, and studying successfully is the regenerative combustion system of heat storage with the ceramic bead, is called for short the RCB system, successfully is used on the glass-melting furnace of 1370 ℃ of operating temperatures.Because the specific area of ceramic bead is bigger tens times than checker brick, the volume of regenerator greatly reduces, and the commutation cycle shortens greatly simultaneously.
Phase at the end of the eighties in last century, the good first-class people of Japan scholar Tanaka passes through the further research of New Regenerative combustion technology and perfect, adopt honeycomb ceramic heat accumulator and in conjunction with low oxygen combustion, the big difficult problem of nitrogen oxide when having solved high-temperature air burning (NOx) discharge capacity, propose the notion of high-temperature and low-oxygen combustion, new height is arrived in this skill upgrading.The New Regenerative combustion technology gets most of the attention with the advantage of its obvious energy-saving effect and favorable environment protection, applies rapidly on multiple industrial furnace in industrially developed country such as Europe, North America, Japan.China actively develops the research and development to regenerative combustion technology since the mid-90 in last century, and steel industry takes the lead in applying, and adopts heating furnace, heat-treatment furnace and the ladle baking facility of regenerative combustion technology to reach hundreds of seats at present.
Though Regenerative Combustion Technology has multiple advantages such as energy-saving and environmental protection, homogeneous heating and low combustion noise, but in actual application, still there are many problems to study and to solve, wherein more serious problem is that stopping up appears in ceramic bead or honeycomb type heat storage in use for some time, has a strong impact on heat recovery efficiency and industrial furnace heating efficiency and ordinary production.Usually the way that solves this class problem all is to wait Awaiting Overhaul even temporary cessation of production to change heat storage, safeguards to actual production and brings white elephant, causes heavy economic losses.
Iron oxide dust in the furnace gas, and cracking takes place and analyses carbon in the coal gas that contains hydrocarbon when high temperature, containing the many coal gas fuel of tar etc. all is to cause heat storage that the main cause of stopping up takes place, particularly the iron oxide dust in the furnace gas by with the contacting and high temperature solid state reaction of refractory material, form low melting point, reduce the material softer melting temperatur, therefore in use cause low melting point to adhere on the heat storage, increased gas-flow resistance, reduced heat storage efficiency, the adhesive capacity of low melting point has been strengthened the capturing ability of heat storage to dust simultaneously, further worsened the heat storage serviceability, even cause large tracts of land to stop up, can't normally use.
This shows that above-mentioned existing heat-accumulating burner obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that heat-accumulating burner exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing heat-accumulating burner exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of New Regenerative burner of new structure with line pulse winding-up decontamination apparatus, can improve general existing heat-accumulating burner, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
