DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-2 In the first embodiment, an industrial waste gas preheating and recovery device includes:

[0022] The recovery tank 10 has an air inlet pipe 11 on the lower end wall and an air outlet pipe 12 on the upper end wall;

[0023] A positioning column 21 is located at the inner center of the recovery tank 10;

[0024] A plurality of partitions 20 are respectively fixedly connected to the periphery of the positioning column 21 and are fixedly connected to the recovery tank 10; the partitions 20, the positioning column 21 and the inner wall of the recovery tank 10 form a recovery chamber 22;

[0025] The baffle plate 30 is rotatably disposed on the upper end of the positioning column 21, and the baffle plate 30 has an exhaust hole 31 at a position corresponding to one of the recovery chambers 22;

[0026] A plurality of heat exchange tubes 50 are respectively disposed in a plurality of recovery chambers 22 , and both ends of the heat exchange tubes 50 respectively penetrate the side walls of the recovery tank 10 .

[0027] This embodiment is implemented as follows:

[0028] When the present application is in use, the heat absorbing medium is poured into one end of the heat exchange tube 50 and poured out from the other end. At the same time, the baffle 30 will rotate. When the exhaust hole 31 on the baffle 30 corresponds to the recovery chamber 22, the industrial waste gas will flow out from the recovery chamber 22 through the exhaust hole 31, while the industrial waste gas in other recovery chambers 22 that do not correspond to the exhaust hole 31 will not flow out. This allows the industrial waste gas to stay in the recovery chamber 22, allowing the medium in the heat exchange tube 50 to absorb heat from the industrial waste gas for a longer time, thereby allowing the heat energy of the industrial waste gas to be absorbed more completely.

[0029] The advantage of the present application over the prior art is that the present application absorbs heat from industrial waste gas more completely.

[0030] See also Figure 1 , 2 , a cover body 40 is fixedly sleeved on the outer wall of the recovery tank 10 at a position corresponding to each recovery chamber 22, the cover body 40 and the outer wall of the recovery tank 10 form a liquid outlet chamber 41, a liquid inlet chamber 43 and a vacuum chamber 45, the vacuum chamber 45 is located between the liquid outlet chamber 41 and the liquid inlet chamber 43, a liquid outlet pipe 42 is provided at a position corresponding to the liquid outlet chamber 41 on the cover body 40, and a liquid inlet pipe 44 is provided at a position corresponding to the liquid inlet chamber 43, one end of the heat exchange tube 50 extends into the liquid outlet chamber 41, and the other end extends into the liquid inlet chamber 43;

[0031] The cover body and the recovery tank form a liquid outlet chamber and a liquid inlet chamber, which enables the medium in the liquid outlet chamber and the liquid inlet chamber to absorb the heat energy of the outer wall of the recovery tank, and has a certain preheating and heat preservation effect.

[0032] See also Figure 2 , the liquid inlet chamber 43 is located above the liquid outlet chamber 41;

[0033] The position where the industrial exhaust gas has the highest thermal energy is close to one end of the air inlet pipe 11 , so the medium in the heat exchange tube 50 flows from top to bottom, so that the industrial exhaust gas with a relatively low temperature at the upper end can preheat the medium in the heat exchange tube 50 .

[0034] See also Figure 1 , 2 A positioning ring 32 is fixedly connected to the upper surface of the baffle 30, a gear ring 33 is fixedly sleeved on the outer circumferential wall of the positioning ring 32, a driving cover 36 is provided on the side wall of the recovery tank 10, a servo motor 34 is fixedly connected to the driving cover 36, and an output end of the servo motor is fixedly connected to a gear 34 meshing with the gear ring 33;

[0035] The servo motor 35 can drive the gear 34 to rotate, the gear 34 drives the gear ring 33 to rotate, the gear ring 33 drives the positioning ring 32 to rotate, and the positioning ring 32 can drive the baffle 30 to rotate.

[0036] The outer circumferential wall of the baffle 30 in the present application is in sliding contact with the inner wall of the recovery tank 10, and the rotating shaft of the baffle 30 is rotatably connected to the positioning column 21 through a bearing.
