Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9, the whole is a vertical arrangement, the cross section of the cylinder 17 is an annular hollow 22, the supporting plate 8 is fixed on the lower end of the cylinder 17 with bolts, the supporting plate 8 has a groove 28, and is connected with the middle hollow 31 of the cylinder 17 There are air holes 27 on the corresponding part. During the working state, the cavity is vacated in the middle, and the convective air from bottom to top can cool the balance of the lower part and the transmission device naturally; A uniform plate 21 with thirteen channels, among the thirteen channels, 4 flue gas channels, 3 air channels, 6 transition areas, and are symmetrically arranged, and the thirteen channels are filled with heat storage bodies , the regenerator adop...

Abstract

The invention discloses a continuous heat accumulating type heat exchanger. A groove (28) and an air hole (27) are arranged on a supporting plate (8), a plurality of channels are arranged in an annular hollow device (22), and heat accumulators are filled in the plurality of channels. A ceramic covering plate (16) with holes is arranged at the upper portion of a cylinder body (17) which is installed on a power transmission device (19). A high-temperature air cap (1) is in butt-joint with the ceramic covering plate (16) with holes, a sealing device is arranged between the high-temperature air cap (1) and the ceramic covering plate (16) with holes, a low-temperature air cap (18) is in butt-joint with the supporting plate (8), and a sealing structure is arranged between the low-temperature air cap (18) and the supporting plate (8). Smoke flows in from an inlet (10), flows through the heat accumulators, and then is exhausted out from an outlet (12), and air flows in from an inlet (13), flows through the heat accumulators, and then is exhausted out from an outlet (11). The high-temperature air cap (1) and the low-temperature air cap (18) are static. A motor and a transmission device drive the cylinder body (17) to rotate at the constant speed, and insulation layers (20) are arranged both inside and outside the motor, the transmission device and the cylinder body (17). The continuous heat accumulating type heat exchanger is small in fluctuation of furnace temperature, furnace pressure and preheated air temperature.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a regenerative heat exchanger, which utilizes the heat of high-temperature flue gas in flues of various industrial furnaces to preheat combustion-supporting air. Background technique [0002] Energy is an important factor restricting the development of my country's national economy. The national "Eleventh Five-Year Plan" clearly puts forward the slogan of energy conservation and emission reduction, and the energy consumption and emission reduction indicators have become binding indicators with legal effect. The "Twelfth Five-Year Plan" has strengthened the requirements for energy conservation and emission reduction, and accelerated the construction of a resource-saving and environment-friendly society. The energy consumption of industrial furnaces accounts for 60% of the total energy consumption of the industry. Compared with developed countries, the average thermal efficiency of industrial fu...
