Description
Technical field
The utility model belongs to the glass industry technical field, is specifically related in a kind of float glass process industry with full-oxygen combustion melting furnaces glass batch smoke pre-heating equipment
Background technology
World today's energy has become the bottleneck of restriction various countries' Economic development, and the industry of some high energy consumptions, high pollution more and more is difficult to adapt to energy shortage and requirement on environmental protection.Float glass industry is the industry of a high energy consumption, the height of energy consumption directly affects the benefit of enterprise now, advocating glass melter energy-saving energetically is the responsibility of glass production enterprise, for setting up the glass industry of energy conservation type, the friendly type recycling economy of environmental protection, developed countries such as America and Europe begin to carry out full-oxygen combustion, and the oxygen of this purity 〉=85% participates in incendiary full-oxygen combustion system.Because the change of firing system causes the change of glass melter structure, the full-oxygen combustion kiln has been cancelled regenerator, port, has been changed ignition system, and input cost is low, and daily amount of oxygen is few, and energy-saving effect is obvious.Can increase output in the intermediary and later stages that the float glass process kiln puts into operation, need not to pay hot repair expenses such as regenerator again, it is fairly obvious that glass melting is stablized its economic benefit more.
Owing to no longer adopt the recoverable regenerator of waste gas heat, directly the spent air temperture of Pai Chuing is up to 1200 ℃, and the heat energy, the raising thermo-efficiency that how to reclaim in the waste gas are the research topics that domestic and international oxy-fuel combustion glass melting furnace technical field is made earnest efforts always.Present stage, people to the approach of flue gas waste heat recovery mainly contain cogeneration, utilizing waste heat for refrigeration, waste heat boiler and waste heat preheating glass batch etc. several by way of.Utilize waste heat boiler to produce steam or cogeneration and can both consume part heat in the flue gas, but the mode of waste heat boiler, cogeneration all has bigger energy waste, heat recovery rate is lower.Utilize waste gas residual heat preheating glass batch can effectively reduce power loss, and founding of glass batch change multistage heating into, improved melting furnaces productivity, can also improve the working conditions of melting furnaces, working life is prolonged.The preheating of whirlwind tube powder, pellet preheating and drum-type preheating are generally adopted in existing glass batch preheating.The preheating of whirlwind tube powder exists outlet temperature limited by flue-gas temperature, interchanger serious wear, the serious problem of exhaust gas dust; , be unfavorable for promoting though but the pellet preheating has avoided smoke contamination facility investment expense big; The drum-type powder has adopted intermediate medium for overcoming flue gas band dirt problem, and twice heat exchange makes equipment increase and time-consuming.
Summary of the invention
The utility model purpose is in order to overcome the defective of above-mentioned prior art, a kind of utilization rate of waste heat that improves flue gas to be provided, energy-saving and cost-reducing full-oxygen combustion melting furnaces glass batch smoke pre-heating equipment.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of full-oxygen combustion melting furnaces glass batch smoke pre-heating equipment connects the glass melter exhaust gases passes, comprises preheater, induced draft fan and exhaust gases passes; It is characterized in that also being provided with mixing section, the glass melter exhaust gases passes communicates with mixing section, and the top of mixing section or outer side edges link to each other with gas blower, and mixing section top connects the preheater bottom by exhaust gases passes, described preheater is vertical structure, and upper side is provided with the capture flue gas system.
Mixing section is the metal mixed chamber, and it includes 5～20 centimetres of aluminum silicate fibers, and skin is the aluminium skin.
Described preheater internal interval is equipped with funnel type and/or roof type baffle plate.The admixtion that enters interchanger forms the annulation bed of material under baffle effect, with the direct contact heat-exchanging of flue gas, improved heat utilization ratio and heat exchange efficiency.
Capture flue gas system described in the utility model is a cyclone.
On the funnel type of preheater inside or roof type baffle plate, be provided with fin, can promote thermal exchange.
The utility model compared to existing technology, beneficial effect mainly shows and is to utilize mixing section that the high-temperature flue gas dilution is fully utilized, adopt shaft preheater, the direct contact heat-exchanging of admixtion and flue gas, the preheating temperature of glass batch and easy to control the quality improves melting rate, save energy, saved cost of investment and running cost, be easy to promote the use of.
