DETAILED DESCRIPTION

[0023] 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.

[0024] The utility model provides a technical solution, please refer to Figure 1 and Figure 2 An environmental protection device for purifying waste gas comprises: a purification kettle 1, the interior of which can store water to recover heat from waste gas, an air inlet pipe 12 connected to the top of the purification kettle 1, a water inlet pipe 11 connected to the right side of the top of the purification kettle 1, and a drain pipe 13 connected to the bottom right side of the purification kettle 1, and the air inlet pipe 12 conveniently connects the waste gas to the second high-temperature bellows 45.

[0025] The bottom of the air inlet pipe 12 is connected to the top of the second high-temperature bellows 45, and the air inlet pipe 12 and the second high-temperature bellows 45 are connected by a flange. The flange increases the connection stability between the air inlet pipe 12 and the second high-temperature bellows 45. The water inlet pipe 11 and the drain pipe 13 facilitate the input of water into the purification kettle 1 to recover heat. The bottom of the purification kettle 1 is connected to a purification chamber 2, which can purify the exhaust gas, and the bottom of the purification chamber 2 is connected to a wastewater pipe 21.

[0026] Butterfly valves are installed on the outside of the wastewater pipe 21 and the drain pipe 13. The wastewater pipe 21 is convenient for discharging the wastewater at the bottom of the purification chamber 2. A filter element 3 is embedded on the right side of the purification chamber 2, and the filter element 3 can discharge the purified waste gas. A circulation mechanism 4 is installed inside the purification kettle 1, and the circulation mechanism 4 can allow the waste gas to flow.

[0027] See also Figure 3 The circulation mechanism 4 includes a float plate 41, which can be driven by boiling water through buoyancy. Slots 42 are evenly spaced on the top of the float plate 41 to facilitate steam discharge. Threaded rods 43 are embedded in the interior of the float plate 41 to facilitate the circulation of exhaust gas. At the same time, the spiral threaded rods 43 can increase the contact time between the exhaust gas and the water source, thereby improving the efficiency of recovering heat energy.

[0028] The top of the threaded rod 43 is connected to a second high-temperature bellows 45. The cooperation between the second high-temperature bellows 45 and the first high-temperature bellows 44 can make the threaded rod 43 driven by the floating plate 41 to shake. The first high-temperature bellows 44 and the second high-temperature bellows 45 can be stretched and retracted elastically. The bottom of the threaded rod 43 is connected to the first high-temperature bellows 44. The end of the first high-temperature bellows 44 away from the threaded rod 43 is connected to an exhaust gas nozzle 441. The exhaust gas nozzle 441 can atomize and discharge the exhaust gas. The first high-temperature bellows 44 and the second high-temperature bellows 45 are respectively inserted into the outside of the purification kettle 1. Pull ropes 46 are connected to both sides of the bottom of the floating plate 41, and the pull ropes 46 can drive the filter plate 61 to shake.

[0029] See also Figure 4 A spray mechanism 5 is installed on the inner top of the purification chamber 2. The spray mechanism 5 includes a water pump 51. The water pump 51 can pump in an external spray water source. The water pump 51 is installed on the left side of the purification chamber 2. The water outlet of the water pump 51 is connected to a water collecting pipe 52 through a short pipe. The water collecting pipe 52 can collect and store the pumped water source. The water collecting pipe 52 is installed on the inner top of the purification chamber 2. The bottom of the water collecting pipe 52 is evenly connected to spray nozzles 53. The spray nozzles 53 can atomize and discharge the pumped water source. The cooperation of the water pump 51, the water collecting pipe 52 and the spray nozzles 53 can atomize the external water source and discharge it into the purification chamber 2 to spray and purify the exhaust gas. The interior of the purification chamber 2 is slidably connected with a filtering mechanism 6.

[0030] The filtering mechanism 6 includes two filter plates 61, which can filter impurities in waste water. The two filter plates 61 are respectively connected to two different pull ropes 46, and the two filter plates 61 are connected by an elastic rubber belt. The setting of the two filter plates 61 can prevent the uncertain movement amplitude of the floating plate from driving the two filter plates 61 to conflict with the inner wall of the purification chamber 2. The two filter plates 61 are respectively slidably connected to the inside of the purification chamber 2, and square plates 62 are evenly connected to the bottom of the filter plates 61. The bottom of the square plates 62 is fixedly connected to a spring 63. The spring 63 cooperates with the square plates 62 to enable the filter plates 61 to return to their original position after movement. The spring 63 is connected to the inner wall of the purification chamber 2, and the top of the filter plate 61 is connected to the bottom of the pull rope 46. The front of the purification kettle 1 and the purification chamber 2 are provided with openable hatches for cleaning and maintaining the interior of the purification kettle 1 or the purification chamber 2.

[0031] In this scheme, the water source is first discharged into the interior of the purification kettle 1 through the water inlet pipe 11, and the butterfly valve outside the drain pipe 13 is closed, the exhaust gas pipeline is connected with the air inlet pipe 12, so that the exhaust gas enters the interior of the second high-temperature bellows 45, and then is discharged into the interior of the purification chamber 2 through the threaded rod 43, the first high-temperature bellows 44 and the exhaust gas nozzle 441, the spray water source is connected with the water pump 51, the water source is pumped out and discharged into the interior of the water collecting pipe 52, and then atomized and discharged through the spray nozzle 53, the exhaust gas is purified, and the treated exhaust gas is discharged through the filter element 3, completing the treatment of the exhaust gas, opening the valve outside the waste water pipe 21, and the waste water at the bottom of the purification chamber 2 can be collected. At the same time, after the use of the device is completed, the purification kettle 1 and the purification chamber 2 can be opened for maintenance and cleaning;

[0032] When the exhaust gas passes through the threaded rod 43, the water source on the inner wall of the purification kettle 1 will be heated by heat transfer for heat recovery. After the water source is heated and boiled, a large number of bubbles will be generated. The bubbles will cause the liquid level of the water source inside the purification kettle 1 to change continuously, and then cause the floating plate 41 to reciprocate up and down, thereby driving the threaded rod 43 to shake, and the carbon deposits and impurities inside it will be cleaned by the shaking threaded rod 43, and discharged into the interior of the purification chamber 2 through the exhaust gas nozzle 441. At the same time, when the floating plate 41 shakes, it will drive the filter plate 61 to shake through the pull rope 46, thereby preventing the particles in the wastewater from clogging the filter plate 61, thereby affecting the speed of wastewater recovery;

[0033] When the waste gas is processed, the heat inside the waste gas is automatically recovered. At the same time, the boiling water generated by the recovered heat is used to drive the float plate 41 to move, and the carbon deposits and impurities inside the threaded rod 43 are shaken off to avoid the accumulation of carbon deposits inside the threaded rod 43 and thus affecting the flow rate of the waste gas in the threaded rod 43. At the same time, the filter plate 61 is driven to shake to avoid the filter plate 61 being blocked by particles in the waste water, thereby increasing the smoothness of the overall use of the device and automatically recovering the energy in the waste gas, saving energy loss and being green and environmentally friendly.
