Furnace

Abstract

The invention provides an energy gathering furnace which belongs to the technical field of high-temperature cracking furnaces, and can be used for solving the problems of poor cracking effect of an existing structure, low yield of a furnace, and the like. The energy gathering furnace is characterized in that a positive-pressure vacuum working region is arranged in a high-temperature furnace body, an external spiral flue is arranged between the outer ring wall of the working region and the inner wall of the furnace body, an internal spiral flue is arranged in the inner ring wall of the working region, inclined heat absorbing damping boards are uniformly distributed in the working region from bottom to top, and a plurality of temperature partitioning plates are sequentially transversely arranged in the external spiral flue and the internal spiral flue from bottom to top to divide a plurality of independent heating spaces. According to the energy gathering furnace, the internal spiral flue and the external spiral flue are provided for performing heat exchanging, so that the heat exchanging area is large, the heat is fully and effectively absorbed, the heat absorbing effect of the heat exchanging manner is ten times that of a common heat exchanging manner; meanwhile, the temperature in the working region is kept stable and slightly fluctuates, so as to ensure that the cracking effect of the energy gathering furnace to organic matters is optimal; the energy gathering furnace has the advantages of excellent energy saving and cracking effects, high yield, reliable product quality, and the like.

Description

technical field [0001] The invention belongs to the technical field of high-temperature cracking furnaces, in particular to a concentrated energy furnace. Background technique [0002] Nowadays, the disposal of municipal solid waste or industrial waste is a worldwide problem, and the shortcomings of the existing treatment methods are very obvious, such as the landfill method occupies land and pollutes the environment; the incineration method is difficult to meet the emission standards, and the operating cost is high; other Methods such as composting are difficult to control and cause secondary pollution to the environment, so they cannot achieve excellent treatment effects. [0003] At present, Chinese patent literature discloses a microwave cracking furnace for garbage, the authorized announcement number is CN 102492442A, which includes at least one microwave cracking furnace, a feeding device, and a discharging device installed in combination with upper and lower parts, an...

Problems solved by technology

[0002] Nowadays, the disposal of municipal solid waste or industrial waste is a worldwide problem, and the shortcomings of the existing treatment methods are very obvious, such as the landfill method occupies land and pollutes the environment; the incineration method is difficult to meet the emission standards, and the operating cost is high; other Methods such as composting are difficult to control and cause secondary pollution to the environment, so they cannot achieve excellent treatment effects

[0003] At present, Chinese patent literature discloses a microwave cracking furnace for garbage, the authorized announcement number is CN 102492442A, which includes at least one microwave cracking furnace, a feeding device, and a discharging device installed in combination with upper and lower parts, and the microwave cracking furnace is equipped with a furnace body , the microwave inlet of the microwave oven chamber is set on the side wall of the furnace body, and a spiral stirring retainer is arranged in the furnace. The stirring and retaining device slows down the falling speed of the crushed material, and the microwave energy is input from the outside of the furnace to crack the crushed material in the furnace, achieving the technical effect of high utilization efficiency of cracking energy and thorough cracking. Although the above structure is designed to reduce the falling speed of the crushed material function, but the principle of microwave heating used by it usually cannot reach a high temperature of five or six hundred degrees, the cracking effect of the scrap is poor, and the productivity of the cracking furnace is low
