Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7, the inner wall of the horizontal cylindrical shell 20 is provided with a thermal insulation layer 14, and the inside of the horizontal cylindrical shell 20 is divided into six equal axial cavities by partitions: the first cavity 1, the second cavity 2. The third chamber 3, the fourth chamber 4, the fifth chamber 5 and the sixth chamber 6, all of the axial chambers are filled with heat storage bodies, and the two ends of the axial chambers are provided with perforated baffles 13 is used to fix the regenerator. The regenerator is divided into: ceramic ball 21 and ceramic honeycomb body 18 according to different flue gas qualities. The perforated baffle 13 is fixed with the horizontal cylindrical shell 20 by bolts, which is easy to disassemble . One end of the horizontal cylin...

Abstract

The invention discloses a horizontal heat accumulating type efficient heat exchanger. The inner wall of a horizontal cylindrical housing (20) is provided with a heat insulation layer (14); the inside of the horizontal cylindrical housing (20) is separated by a separating plate to form six identical axial cavities, namely a first cavity (1), a second cavity (2), a third cavity (3), a fourth cavity (4), a fifth cavity (5) and a sixth cavity (6); each of the axial cavities is filled with a heat accumulating body; a rotating shaft (11) is provided with two rotors (12), which are correspondingly connected with the two ends of the axial cavities respectively; each rotor (12) is provided with three air jackets (19), which are separately arranged in the circumferential direction; and the rotors divide a passage into two parts. According to the horizontal heat accumulating type efficient heat exchanger disclosed by the invention, a heat accumulating chamber with large weight is fixed, the afterheat of smoke is extremely recovered, and the heat efficiency of a system is obviously improved.

Description

technical field [0001] The invention relates to a regenerative heat exchange device, which uses the heat of high-temperature flue gas in various industrial kiln flues to preheat combustion-supporting air. A cylinder filled with regenerators and two sets of air jacket devices driven by servo motors at both ends realize a regenerative heat exchanger that continuously provides hot air to the burner and discharges cooling flue gas. Background technique [0002] The tension and shortage of energy in our country is a foregone conclusion, which has seriously affected the economic development. At present, the energy utilization rate of industrial furnaces in my country is generally low. Now there are some forging heating furnaces. Due to the characteristics of the process operation, the exhaust gas temperature of most forging heating furnaces is higher than 1000 ° C, because there is no high-efficiency waste heat recovery device suitable for long-term use. , The heat loss of the exh...
