Embodiment Construction

[0031] The present invention will be further described below in conjunction with the drawings.

[0032] See figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 with Picture 9 , The overall arrangement is vertical, the cross section of the cylinder body 17 is an annular hollow 22, the pallet 8 is fixedly installed on the lower end of the cylinder body 17 with bolts, the pallet 8 is provided with a groove 28, and is hollow 31 between the cylinder body 17 The corresponding part is provided with an air hole 27. When the cavity is in the working state, the convective air flowing from the bottom to the top can naturally cool the lower balance and the transmission device; the annular hollow 22 is provided with a plurality of axially dividing the annular hollow 22 Thirteen channels are evenly inserted into the board 21. Among the 13 channels, 4 are flue gas channels, 3 are air channels, 6 are transition areas, and are arranged symmetrically. The 13...

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 our national economy. The national "Eleventh Five-Year Plan" clearly puts forward the slogan of energy conservation and emission reduction, and energy consumption and emission reduction indicators have become legally binding and binding indicators. 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 industrial energy consumption. Compared with developed countries, the average thermal efficiency of industrial furnaces in my country ...
