DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In this embodiment, a waste gas treatment device for recycling waste heat of high-temperature waste gas includes a mounting plate 1, two support plates 2 are fixedly mounted on the bottom of the mounting plate 1, a heating furnace 3 is movably mounted inside the mounting plate 1, an air intake pipe 4 is fixedly mounted on the left side of the heating furnace 3, a filtering mechanism 5 is arranged on the top of the heating furnace 3, a connecting pipe 6 is movably mounted on the output end of the filtering mechanism 5, and a recovery mechanism 7 is arranged on the output end of the connecting pipe 6;

[0021] The filtering mechanism 5 includes a fixed plate 501, two fixed plates 501 are fixedly installed on the top of the heating furnace 3, a filter box 502 is fixedly installed on the top of the two fixed plates 501, a flange connecting pipe 503 is fixedly installed on the bottom of the filter box 502, and a limiting slide plate 504 is fixedly installed on the left and right walls of the filter box 502. A mounting ring plate 505 is arranged inside the limiting slide plate 504, and a filter mesh plate 506 is movably installed inside the mounting ring plate 505. A sealing ring 507 is movably installed on the front of the filter box 502, and a cover plate 508 is threadedly connected to the front of the filter box 502.

[0022] The recovery mechanism 7 includes a recovery box 701, and the recovery box 701 is movably installed at the output end of the connecting pipe 6. A heating chamber 702 is arranged inside the recovery box 701, and a heat conduction water tank 703 is arranged inside the heating chamber 702. A water inlet pipe 704 is fixedly installed on the right side of the heat conduction water tank 703, a water pumping pipe 705 is fixedly installed on the right side of the heat conduction water tank 703, and a solenoid valve water outlet pipe 706 is fixedly installed at the bottom of the recovery box 701.

[0023] In the case implementation, the setting of the mounting plate 1 can install and fix the heating furnace 3 and the recovery box 701, and the supporting plate 2 can support the equipment. The setting of the heating furnace 3 can heat the exhaust gas to increase its temperature. The setting of the air intake pipe 4 can directly transmit the exhaust gas to the inside of the heating furnace 3. At the same time, the setting of the connecting pipe 6 can transport the filtered hot gas to the inside of the heating chamber 702.

[0024] When implementing, follow these steps:

[0025] 1) The exhaust gas is first transported to the interior of the heating furnace 3 for heating. After the heated exhaust gas undergoes a heating reaction, it is transported to the interior of the filter box 502 through the flange connection pipe 503. At the same time, after being filtered through the filter screen 506, harmful impurities in the exhaust gas are filtered out;

[0026] 2) Then, the tower-shaped design of the filter box 502 is used to gather the filtered hot air, accelerating the hot air to enter the interior of the connecting pipe 6 for the next delivery. When the filter device needs to be replaced, it is only necessary to twist the bolts, remove the cover plate, and pull the mounting ring plate 505 to pull out the filter screen plate 506 for further replacement;

[0027] 3) The hot air is then transported to the inside of the recovery box 701 through the connecting pipe 6, and enters the inside of the heating chamber 702. The water conduction water tank 703 can be filled with water through the water inlet pipe 704. The water conduction water tank 703 conducts the heat of the hot air inside the heating chamber 702 to heat the water;

[0028] 4) Finally, by connecting the pumping equipment, the hot water inside the heat transfer water tank 703 can be pumped out using the pumping pipe 705. At the same time, when the equipment is not running, the hot air will condense into water inside the heating chamber 702, and the condensed water can be discharged through the solenoid valve outlet pipe 706.

[0029] In summary, the exhaust gas treatment device for recycling waste heat from high-temperature exhaust gas has a better filtering effect by setting up the filtering mechanism 5, and can effectively filter out harmful impurities in the exhaust gas. At the same time, by changing the shape, the air rising circulation path can be strengthened to form an air gathering effect and accelerate the air flow. At the same time, the setting of the recovery mechanism 7 can utilize the heat in the exhaust gas to heat the cold water, and at the same time, it can prevent the water after the hot air condenses inside the equipment from being discharged, further improving the function of the equipment. Compared with this technical solution, the function is further improved and the use effect is enhanced.
