Embodiment Construction
[0010] Attached below Figure 1-Figure 3 The present invention is described in detail:
[0011] The present invention provides an energy-saving hot blast stove through improvement. The structure of the hot blast stove is divided into two parts, one part is the flue gas channel part (indicated by a thick long arrow line in the figure); the other part is the hot blast channel part (Fig. Indicated by thin dotted arrows). The two parts are completely separated, and the heat is conducted to the hot air through the metal cylinder heated by the flue gas and the heat conduction plate, and the flue gas does not pollute the hot air, forming their own channels. As shown in the figure, the composition of the hot blast stove includes air door, furnace door, air inlet pipe, jet plate, chimney, outer cylinder, shell, heat insulation layer, inner spiral heat conduction plate, outer spiral heat conduction plate, external heating Cylinder, inner heating cylinder, top plate, channel bottom pla...

The invention provides an energy-saving hot blast heater, which is characterized in that an air door is located at the bottommost part of a furnace body; a furnace door is located above the air door; a combustion chamber is composed of the furnace door and a space which is formed by a smoke barrel, an outer heating barrel and an inner heating barrel; an air inlet pipe is internally provided with a jet flow plate and the smoke barrel is located at the center of the furnace body and above the combustion chamber; a heat-isolating layer is arranged between an outer barrel and a shell; an inner spiral heat guide plate is arranged below the inner heating barrel and the smoke barrel; an outer spiral heat guide plate is arranged below the outer heating barrel and the outer barrel; a high-temperature region is formed between the inner heating barrel and the smoke barrel; the inner heating barrel is located between the smoke barrel and the outer heating barrel; a heat guide sheet is located above the smoke barrel and a low-temperature region is formed between the outer barrel and the outer heating barrel; a channel lateral plate is located between a top plate and a channel bottom plate; a temperature controller is arranged on the shell and is used for easily detecting, operating and controlling a small fan; the small fan is arranged outside the furnace body and below the combustion chamber; and a large fan is arranged at the outer edge of the air inlet pipe. The defects that the traditional hot blast heater is poor in heating effect and heat transmission effect are overcome through improvement; and the invention provides the energy-saving hot blast heater through the improvement so that the contact area with the air can be enlarged and the aim of good heat transmission effect is realized.
Description
technical field [0001] The invention relates to an energy-saving hot blast stove. Background technique [0002] Hot blast stoves are widely used in many fields. Traditional hot blast stoves generally include a furnace, a furnace body and a furnace seat. The furnace body is surrounded by air interlayers, and air inlets and air outlets are provided in the air interlayers. However, the traditional hot blast stoves After heating the air, the hot smoke from the hot blast stove is directly discharged into the atmosphere through the chimney. The exhausted smoke takes away a lot of heat, the heating effect is poor, the heat transfer effect is poor, and a lot of energy is wasted. In addition, this traditional The hot blast stove achieves the purpose of heating the cold air by conducting heat conduction to the cold air in the air interlayer through the high temperature generated by the combustion of fuel in the furnace. However, due to the low heat exchange efficiency of this traditio...
