Description
Technical Field
[0001] The utility model relates to the technical field of catalytic mechanisms, in particular to a catalytic mechanism with a waste heat recovery function. Background Art
[0002] A catalytic combustion device refers to a device or equipment that burns under the action of a catalyst. The working principle of the catalytic combustion device is: with the help of a catalyst, the organic waste gas is flamelessly burned at a relatively low ignition temperature, and the organic waste gas is decomposed into non-toxic carbon dioxide and water vapor. For example, the exhaust gas catalytic heat storage combustion device with improved combustion efficiency, which is published as "CN216716251U", has a first catalytic mechanism, a second catalytic mechanism and a third catalytic mechanism that cooperate with each other, which can improve the catalytic efficiency of the present application while making the exhaust gas catalyzed more fully. The first protective cover can cover the catalytic chamber to avoid the overflow of uncatalyzed exhaust gas in the catalytic chamber as much as possible. However, the exhaust gas catalytic heat storage combustion device still has the following disadvantages during actual use;
[0003] When the above mechanism is in use, the exhaust gas will generate a large amount of heat energy after the catalytic reaction, and the heat energy is directly discharged from the outlet along with the gas and cannot be effectively recovered, resulting in heat waste. At the same time, after the device has been used for a long time, a large number of combustion residual impurities are attached to its inner wall, making it difficult for the later staff to clean them up. In the long run, it is easy to corrode the inner wall of the device, thereby affecting the service life of the device. Moreover, after the filter net has been used for a long time, its filter holes will be blocked by impurities in the exhaust gas, thereby affecting the subsequent filtering effect of the exhaust gas.

[0033] like Figure 1-Figure 4As shown, water is added to the U-shaped tube 5, and the exhaust gas enters the catalyst chamber 1 through the air inlet 2, and then the impurities in the exhaust gas are filtered through the filter 4 to prevent them from polluting the inside of the catalyst chamber 1. Then the exhaust gas is catalytically burned by the catalyst 7, and the heat generated by the combustion is absorbed by the U-shaped tube 5 and heats the water inside. Then the solenoid valve 8 is started, so that the heated water enters the liquid storage box 6 to realize the function of waste heat recovery. After that, the burned exhaust gas is discharged from the exhaust port 3. At this time, the water pump is started, and the water inside the liquid storage box 6 is transported to the turntable 14 through the hose 9, and the water is sprayed onto the inner wall of the catalyst chamber 1 through the nozzle. At the same time, the rotating rod 10 drives the transmission rod 15 to rotate synchronously using the pulley assembly.
