Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment and recovery devices, and more specifically to an environmentally friendly boiler combustion waste gas treatment and recovery device. Background Art

[0002] Boiler combustion waste gas refers to the gas emissions generated during the combustion of fuel in the boiler. These waste gases usually contain other dust particles such as carbon dioxide, nitrogen oxides, carbon monoxide, sulfides, etc. Among them, carbon dioxide, nitrogen oxides and carbon monoxide contained in the waste gas are harmful gases. If they are directly discharged into the outside air, they are easy to pollute the environment. Therefore, the waste gas needs to be treated and recycled.

[0003] When the existing environmentally friendly boiler combustion waste gas treatment and recovery device is in use, the waste gas is usually transported to a recovery tank through a connecting pipe, separated and filtered through multiple activated carbon filters in the recovery tank or sprayed with an alkaline solution, and finally discharged to the outside through a discharge port, thereby reducing the emission of harmful substances in the boiler combustion waste gas.

[0004] In actual use of the prior art, since the adsorption and spraying of alkaline solution through the activated carbon filter cannot ensure that all exhaust gas is in contact with the alkaline solution, or the solution at the front end of the activated carbon filter is quickly saturated and the rear end cannot be fully utilized, a small amount of harmful gas is discharged into the outside when it is discharged, causing environmental pollution.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an environmentally friendly boiler combustion waste gas treatment and recovery device. Summary of the invention

[0006] The purpose of the present invention is to provide an environmentally friendly boiler combustion waste gas treatment and recovery device to solve the above-mentioned problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] An environmentally friendly boiler combustion waste gas treatment and recovery device comprises a recovery tank, a waste gas treatment component and a cleaning component, wherein the inner cavity top wall of the recovery tank is fixedly connected with a motor, and the output shaft end of the motor is fixedly connected with a rotating rod through a coupling; the waste gas treatment component comprises a filter plate fixedly mounted on one end of the rotating rod, a filter screen is arranged in the inner cavity of the recovery tank and below the filter plate, the lower surface of the filter screen and the inner cavity of the recovery tank are fixedly mounted with the waste gas treatment plate, the waste gas treatment plate and the filter plate are provided with corresponding waste gas treatment channels inside, and the lower surface of the filter screen is fixedly connected with a plurality of elastic ropes matching the waste gas treatment channels; the cleaning component comprises a cleaning ball fixedly mounted on one end of the elastic rope, the inner cavity of the cleaning ball is provided with a piston cylinder fixedly connected, one end of the piston cylinder is penetrated and connected with an air bag, the inner cavity of the piston cylinder is slidably connected with a magnet 1, a telescopic rod is fixedly connected between the magnet 1 and the inner wall of the air bag, and a cleaning brush is fixedly connected with the outer surface of the air bag;

[0009] As a further improvement of the present invention, the inner wall of the recovery tank is fixedly connected with an annular water pipe, the outer surface of the annular water pipe is obliquely connected with multiple spray guns, the outer surface of the annular water pipe is provided with a water inlet pipe, the water inlet pipe is inserted into the outer surface of the recovery tank, the annular water pipe surrounds the inner wall of the recovery tank to ensure that the alkaline solution can be evenly distributed inside the recovery tank, and is connected to an external alkaline solution storage tank through the water inlet pipe to receive the alkaline solution, so that it passes through the water inlet pipe, and the alkaline solution can be pumped into the annular water pipe and then evenly sprayed into the recovery tank through the spray gun.

[0010] As a further improvement of the present invention, the outer surface of the telescopic rod is sleeved with a spring, one end of the spring is connected to the bottom wall of the inner cavity of the airbag, and the other end is connected to the lower surface of magnet one. The telescopic rod and the spring act together on the inside of the cleaning ball, and the cleaning function of the cleaning ball is realized by the up and down movement of magnet one. At the same time, the spring provides the necessary restoring force to ensure that the cleaning ball can smoothly return to its original position after completing the cleaning action.

[0011] As a further improvement of the present invention, the exhaust gas treatment channel on the inner wall of the filter plate is fixedly connected with magnet two which repel each other with magnet one. The repulsive force between magnet two and magnet one pushes the air bag in the cleaning ball to expand, so that the cleaning brush contacts the inner wall of the exhaust gas treatment channel for cleaning.

[0012] As a further improvement of the present invention, an air inlet is fixedly connected to the bottom of the exhaust gas treatment channel. The air inlet is trumpet-shaped and is larger at the top and smaller at the bottom. The trumpet-shaped air inlet helps the exhaust gas to enter the exhaust gas treatment channel smoothly, and can prevent the exhaust gas from re-entering the channel being cleaned when the cleaning ball falls, and can also prevent the cleaning ball from accidentally falling out of the exhaust gas treatment channel during the falling process.

[0013] As a further improvement of the present invention, a magnetic shielding layer is fixedly connected to the upper end of the filter screen, and the magnetic shielding layer is provided with a hole for the magnetic field of magnet two to pass through the exhaust gas treatment channel and repel magnet one, thereby ensuring that the cleaning balls in each exhaust gas treatment channel work independently and are not affected by the magnets in other channels.

[0014] As a further improvement of the present invention, the piston cylinder and the airbag are filled with gas, and the airbag is expanded by the repulsive force of magnet 1, thereby pushing the cleaning brush to contact the inner wall of the exhaust gas treatment channel for cleaning.

[0015] As a further improvement of the present invention, the bottom annular array of the recovery tank has multiple support rods, the side of the recovery tank is provided with a connecting pipe, the bottom of the recovery tank is provided with a discharge pipe, the outer surface of the discharge pipe is movably connected with a sealing cover, and the top of the recovery tank is provided with an exhaust pipe to allow the waste gas to enter the recovery tank through the connecting pipe. The discharge pipe is convenient for regularly discharging the waste gas in the recovery tank and the sulfite solution and dust garbage produced by the alkaline solution, and the discharge port discharges the purified waste gas into the outside air.

[0016] As a further improvement of the present invention, the diameter of the cleaning ball is smaller than the diameter of the exhaust gas treatment channel, ensuring that it can move freely in the exhaust gas treatment channel without affecting the normal flow of the exhaust gas.

[0017] As a further improvement of the present invention, the elastic rope is made of waterproof material to ensure that the elastic rope can still maintain good elasticity and durability in a humid environment.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) This solution drives the filter plate to rotate through the cooperation of the motor and the rotating rod, which helps to disperse the alkaline solution sprayed by the spray gun and allow it to enter the exhaust gas treatment channel to form a water film. The exhaust gas floats upward through the exhaust gas treatment channel and contacts the alkaline solution, which can increase the weight of the dust in the exhaust gas and cause it to settle. At the same time, the cleaning ball swings around due to the elastic rope and the force of the exhaust gas floating upward, and collides with the inner wall of the exhaust gas treatment channel, which helps to disperse the exhaust gas and clean the inner wall of the exhaust gas treatment channel, thereby effectively neutralizing harmful components such as acidic gases and ensuring that the discharged gas is cleaner.

[0020] (2) When the spray gun continuously sprays the alkaline solution, the water film with dust adhering to the inner wall of the exhaust gas treatment channel will be washed off and fall into the recovery tank through the air inlet. The dust in the water film will eventually settle to the bottom of the recovery tank. The alkaline solution sprayed by the spray gun can effectively neutralize the acidic gas in the exhaust gas and reduce the emission of harmful substances. The dust will settle at the bottom of the recovery tank more due to the absorption of water, reducing the suspended particulate matter in the air. At the same time, the movement of the cleaning ball helps to better disperse the exhaust gas, increase the contact opportunity between the exhaust gas and the alkaline solution, and improve the purification efficiency.

[0021] (3) The alkaline solution that floats above the filter plate through the exhaust gas treatment channel and is sprayed out by the spray gun and dispersed by the filter plate can perform secondary treatment on the harmful gases contained in the exhaust gas, thereby avoiding the situation where the traditional exhaust gas treatment and recovery device cannot completely treat the harmful gases in the exhaust gas, resulting in a small amount of harmful gases being discharged into the outside world in the later stage and causing environmental pollution, thereby improving the separation efficiency of harmful gases, reducing the total amount of harmful substances discharged into the atmosphere, and reducing the impact on the environment.

[0022] (4) When the filter plate rotates, magnet 2 generates a repulsive force with magnet 1 in a certain exhaust gas treatment channel. This repulsive force pushes the gas in the cleaning ball into the airbag, causing the airbag to expand, so that the cleaning brush on the surface of the airbag contacts the inner wall of the exhaust gas treatment channel and starts self-cleaning. At the same time, the cleaning ball falls and blocks the air inlet to prevent the exhaust gas from entering the channel being cleaned again.

[0023] (5) When magnet two moves away from magnet one, the repulsive force weakens, and magnet one rises again under the action of the spring and the telescopic rod. The cleaning ball returns to its original position due to the elasticity of the elastic rope. When the filter plate is driven by the motor and the rotating rod to rotate continuously, a similar cleaning process can be performed on other exhaust gas treatment channels. At the same time, the magnetic shielding layer below prevents the magnets between different exhaust gas treatment channels from interfering with each other, ensuring that the cleaning process of each exhaust gas treatment channel is carried out independently, so that the water film and residue in the exhaust gas treatment channel can be cleaned to ensure its ventilation effect.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1-6 An environmentally friendly boiler combustion waste gas treatment and recovery device includes a recovery tank 1, a waste gas treatment component 6 and a cleaning component 7. The top wall of the inner cavity of the recovery tank 1 is fixedly connected to a motor 4, and the output shaft end of the motor 4 is fixedly connected to a rotating rod 5 through a coupling.

[0038] Specifically, the exhaust gas treatment component 6 includes a filter plate 601 fixedly mounted on one end of the rotating rod 5. The rotating filter plate 601 helps to break up the sprayed alkaline solution into fine droplets. These droplets enter the exhaust gas treatment channel 604 together with the exhaust gas. In the exhaust gas treatment channel 604, the droplets come into contact with the exhaust gas, and some of the droplets adhere to the inner wall of the channel to form a thin water film. The presence of the water film enables the pollutants in the exhaust gas (such as particulate matter, harmful gases, etc.) to come into contact with the alkaline solution, undergo a chemical reaction, and thus be absorbed or neutralized.

[0039] A filter screen 602 is arranged under the inner cavity of the recovery tank 1 and the filter plate 601, and an exhaust gas treatment plate 603 is fixedly installed on the lower surface of the filter screen 602 and the inner cavity of the recovery tank 1. Corresponding exhaust gas treatment channels 604 are opened inside the exhaust gas treatment plate 603 and the filter plate 601, and a plurality of elastic ropes 605 matching the exhaust gas treatment channels 604 are fixedly connected to the lower surface of the filter screen 602. The cleaning component 7 includes a cleaning ball 701 fixedly installed at one end of the elastic rope 605. The cleaning ball 701 will generate resistance to the exhaust gas as the exhaust gas moves upward, causing the exhaust gas to disperse and continue to float upward and contact the water film. When the cleaning ball 701 falls, the cleaning brush 706 will scrape off the residue on the inner wall, and at the same time, the cleaning ball 701 blocks the air inlet 606 to ensure that the exhaust gas treatment channel 604 being cleaned is not polluted by new exhaust gas.

[0040] An annular water pipe 2 is fixedly connected to the inner wall of the recovery tank 1, and a plurality of spray guns 3 are obliquely connected to the outer surface of the annular water pipe 2. A water inlet pipe 8 is arranged on the outer surface of the annular water pipe 2, and the water inlet pipe 8 is inserted into the outer surface of the recovery tank 1. The alkaline solution sprayed by the spray gun 3 can effectively neutralize the acid gas in the exhaust gas and reduce the emission of harmful substances. The dust becomes heavier due to the absorption of moisture and is more likely to settle, thereby reducing the suspended particulate matter in the air. An air inlet 606 is fixedly connected to the bottom of the exhaust gas treatment channel 604. The air inlet 606 is trumpet-shaped and is larger at the top and smaller at the bottom.

[0041] Furthermore, the starter motor 4 drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the filter plate 601 to rotate, so that the filter plate 601 rotates to break up the sprayed alkaline solution into fine droplets, and enter the exhaust gas treatment channel 604 through the filter plate 601 and the exhaust gas treatment plate 603, forming a water film on its inner wall. The exhaust gas floats upward through multiple exhaust gas treatment channels 604 and contacts with the dripping alkaline solution. During the contact process, the dust in the exhaust gas becomes heavier due to the absorption of water and gradually settles to the bottom of the recovery tank 1. At the same time, the cleaning ball 701 will generate resistance to the exhaust gas as the exhaust gas moves upward, prompting the exhaust gas to disperse and continue to float upward and contact with the water film, so that the dust in the exhaust gas can be separated more effectively, and the exhaust gas and alkali are increased. The cleaning ball 701 swings around due to the elastic rope 605 and the upward force of the exhaust gas, and collides with the exhaust gas treatment channel 604, which helps to further disperse the exhaust gas and increase the contact area between the exhaust gas and the alkaline solution, which helps to distribute the dust in the exhaust gas more evenly. When the spray gun 3 continues to spray the alkaline solution, the water film with dust adhering to the inner wall of the exhaust gas treatment channel 604 will be washed down and fall into the recovery tank 1 through the air inlet 606, so that the dust in the water film will eventually settle to the bottom of the recovery tank 1, so that the alkaline solution sprayed by the spray gun 3 can effectively neutralize the acidic gas in the exhaust gas, reduce the emission of harmful substances, and the dust is heavier and settles at the bottom of the recovery tank 1 due to the absorption of moisture, reducing the suspended particulate matter in the air.

[0042] Embodiment 2:

[0043] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, and the top wall of the inner cavity of the recovery tank 1 is fixedly connected with a motor 4, and the output shaft end of the motor 4 is fixedly connected with a rotating rod 5 through a coupling.

[0044] Specifically, the cleaning member 7 includes a cleaning ball 701 fixedly mounted at one end of the elastic rope 605, the inner cavity of the cleaning ball 701 is provided with a piston cylinder 702 fixedly connected, one end of the piston cylinder 702 is penetrated and connected with an air bag 703, the inner cavity of the piston cylinder 702 is slidably connected with a magnet 704, a telescopic rod 705 is fixedly connected between the magnet 704 and the inner wall of the air bag 703, a cleaning brush 706 is fixedly connected to the outer surface of the air bag 703, a spring 707 is sleeved on the outer surface of the telescopic rod 705, one end of the spring 707 is connected to the bottom wall of the inner cavity of the air bag 703, and the other end is connected to the lower surface of the magnet 704 Next, the exhaust gas treatment channel 604 on the inner wall of the filter plate 601 is fixedly connected with a magnet 2 9 which repels each other with the magnet 1 704. Since the magnet 1 704 and the magnet 2 9 have the same magnetic poles facing each other, one of the properties of magnets is that the same magnetic poles (i.e. the same polarity) will repel each other, while the opposite magnetic poles (i.e. different polarities) will attract each other. Therefore, when the edges or ends of the magnet 1 704 and the magnet 2 9 correspond to each other, the same magnetic poles will generate a repulsive force and push them to move downward. The piston cylinder 702 and the airbag 703 are filled with gas, and the diameter of the cleaning ball 701 is smaller than the diameter of the exhaust gas treatment channel 604.

[0045] A magnetic shielding layer 607 is fixedly connected to the upper end of the filter screen 602, and the magnetic shielding layer 607 is provided with a hole for the magnetic field of magnet 2 9 to pass through the exhaust gas treatment channel 604 and repel magnet 1 704. The magnetic shielding layer 607 is a material or structure used to block or weaken the transmission of the magnetic field. Its materials include soft magnetic materials such as iron, nickel alloys, etc. These materials can absorb or guide magnetic field lines, thereby reducing the penetration of the magnetic field. The magnetic shielding layer 607 ensures that repulsive force is generated only when the filter plate 601 rotates and magnet 2 9 is aligned with the edge or completely aligned with magnet 1 704, thereby triggering the action of the cleaning ball 701, thereby preventing the magnetic field of magnet 2 9 from affecting the cleaning balls 701 in other exhaust gas treatment channels 604 that do not correspond to it, ensuring that the cleaning process of each exhaust gas treatment channel 604 is carried out independently to avoid mutual interference.

[0046] Furthermore, when the filter plate 601 rotates, it drives the magnet 2 9 to correspond to the magnet 1 704 in a waste gas treatment channel 604, and a repulsive force is generated. The magnet 1 704 in the cleaning ball 701 is acted upon by the repulsive force, pushing the gas in the piston cylinder 702 into the airbag 703. The airbag 703 expands and brings the cleaning brush 706 into contact with the waste gas treatment channel 604. When the cleaning ball 701 falls, the cleaning brush 706 continues to scrape off the residue on the inner wall of the waste gas treatment channel 604. The cleaning ball 701 continues to fall. It falls to block the air inlet 606, preventing the exhaust gas from re-entering the exhaust gas treatment channel 604 being cleaned. When the filter plate 601 drives magnet 2 9 away from the exhaust gas treatment channel 604, the repulsive force on magnet 1 704 is weakened. When magnet 1 704 moves, it drives the telescopic rod 705 and the spring 707 to be compressed, and uses the force of the telescopic rod 705 and the spring 707 to drive magnet 1 704 to start moving upward. The cleaning ball 701 then moves upward through the elastic rope 605 and returns to its initial position.

[0047] The working principle of the present invention is as follows: when in use, the exhaust gas generated by the combustion of the boiler is connected through the connecting pipe 10, so that the exhaust gas enters the recovery tank 1 through the connecting pipe 10, and the water inlet pipe 8 is connected to the alkaline solution storage tank, so that the alkaline solution can enter the annular water pipe 2 through the water inlet pipe 8, and the annular water pipe 2 evenly transports the alkaline solution to the spray gun 3, and sprays it into the recovery tank 1 through the spray gun 3, and at the same time, the motor 4 is started to drive the rotating rod 5 to rotate, and when the rotating rod 5 rotates, it will drive the filter plate 601 to rotate, so that the filter plate 601 rotates to break up the sprayed alkaline solution into fine droplets, which enter the exhaust gas treatment channel 604 through the filter plate 601 and the exhaust gas treatment plate 603, forming a water film on its inner wall. The exhaust gas floats upward through multiple exhaust gas treatment channels 604 and contacts with the dripping alkaline solution. During the contact process, the dust in the exhaust gas becomes heavier due to the absorption of moisture and gradually settles to the bottom of the recovery tank 1. At the same time, the cleaning ball 701 will generate resistance to the exhaust gas as it moves upward, causing the exhaust gas to disperse and continue to float upward and contact with the water film.

[0048] Subsequently, the cleaning ball 701 swings around due to the elastic rope 605 and the upward force of the exhaust gas, and collides with the exhaust gas treatment channel 604. When the spray gun 3 continues to spray the alkaline solution, the water film with dust adhering to the inner wall of the exhaust gas treatment channel 604 will be washed down, and fall into the recovery tank 1 through the air inlet 606, so that the dust in the water film will eventually settle to the bottom of the recovery tank 1. Further, when the separated exhaust gas floats to the top of the filter plate 601 through the exhaust gas treatment channel 604, the alkaline solution broken up by the filter plate 601 is in more full contact with the exhaust gas, thereby realizing secondary treatment of the exhaust gas and improving the filtration efficiency of harmful gases. The treated exhaust gas is then discharged into the external environment through the exhaust port, thereby improving the exhaust gas purification efficiency and reducing environmental pollution.

[0049] When the filter plate 601 rotates, it drives the magnet 29 to correspond to the magnet 1 704 in a waste gas treatment channel 604, and a repulsive force is generated. The magnet 1 704 in the cleaning ball 701 is acted upon by the repulsive force, pushing the gas in the piston cylinder 702 into the airbag 703. The airbag 703 expands and brings the cleaning brush 706 into contact with the waste gas treatment channel 604. When the cleaning ball 701 falls, the cleaning brush 706 continues to scrape off the residue on the inner wall of the waste gas treatment channel 604. The cleaning ball 701 continues to fall until it blocks the air inlet 606, preventing the waste gas from entering the waste gas treatment channel 604 being cleaned again. When plate 601 drives magnet 2 9 away from this exhaust gas treatment channel 604, the repulsive force on magnet 1 704 is weakened. When magnet 1 704 moves, it will drive the telescopic rod 705 and spring 707 to be compressed, and use the force of telescopic rod 705 and spring 707 to drive magnet 1 704 to start moving upward, and the cleaning ball 701 moves upward through the elastic rope 605. When the filter plate 601 continues to rotate, other exhaust gas treatment channels 604 can be continuously self-cleaned, and the magnetic shielding layer 607 on the filter net 602 can be used to prevent the cleaning work of other cleaning balls 701 that do not correspond to magnet 2 9 from being affected.

[0050] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
