DETAILED DESCRIPTION

[0046] The following will be combined with 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 of 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.

[0047] Example 1

[0048] like Figure 1~Figure 3 As shown, this embodiment proposes a ship heavy oil combustion flue gas pretreatment device, comprising:

[0049] The preliminary treatment unit 1 is used to absorb impurities and moisture in the flue gas;

[0050] Secondary treatment element 2, the flue gas passes through the primary treatment element 1 and the secondary treatment element 2 in sequence;

[0051] Secondary processing part 2 includes:

[0052] The processing box 3 is connected to the preliminary processing part 1, and the processing box 3 has a chute 4 and an exhaust port 23;

[0053] The absorber 5 is slidably arranged in the slide groove 4. After sliding, the absorber 5 is used to absorb and process the flue gas.

[0054] In this embodiment, in order to solve the problem of slow overall treatment efficiency of the flue gas pretreatment equipment using fixed installation in the related technology, this scheme is provided with a double filtration method. First, a primary filtration is performed through the preliminary treatment component 1 to filter out most of the water vapor generated in the flue gas. The preliminary treatment component is used to be placed after the desulfurization device process and before the decarbonization device. Then the flue gas is further treated by the secondary treatment component 2. It is worth noting that the absorption component 5 in the secondary filter component in this scheme is installed in a sliding manner. When the flue gas is large and the smoke concentration and pressure in the overall treatment box 3 are large, the absorption component 5 can gradually slide with the continuous input of the flue gas, and then the flue gas is absorbed for a long time. The absorption component 5 can be a decarbonizable absorption component according to specific needs. For example, in this way, the harmless treatment efficiency of the flue gas of this scheme is greatly improved, and it has extremely high practical value.

[0055] Further, the processing box 3 comprises:

[0056] The main body 6 has a communication port, and the exhaust port 23 is located on the main body 6;

[0057] The air intake box 8 is arranged on the main body 6 and is connected with the main body 6 through a connecting port. The air intake box 8 has an air intake pipe 31 , and the preliminary treatment unit 1 is connected with the air intake box 8 through the air intake pipe 31 .

[0058] In this embodiment, in order to ensure that the concentration of incoming smoke reaches the absorption threshold of the absorber 5 and avoid it being discharged without being absorbed and processed due to a low concentration, the processing box 3 of this scheme first accumulates it in the air intake box 8 and then discharges it into the main body 6 for processing the smoke, wherein the air intake box 8 and the main body 6 are connected through a connecting port.

[0059] Furthermore, the main body 6 has a drain port 35, and the secondary treatment part 2 further includes:

[0060] The vent pipe 10 is rotatably arranged on the air inlet box 8 and passes through the communication port. The vent pipe 10 has an air inlet hole 11 and an air outlet hole 12. The air inlet hole 11 is located in the air inlet box 8, and the air outlet hole 12 is located in the main body 6. After the vent pipe 10 rotates, smoke enters from the air inlet hole 11 and is discharged from the air outlet hole 12. The absorber 5 is located between the air outlet hole 12 and the exhaust port 23.

[0061] The spraying member 32 is arranged at the top of the main body 6, and has a liquid inlet 33 and a plurality of spraying ports 34. The spraying liquid sprayed from the spraying ports 34 flows relative to the flue gas.

[0062] In this embodiment, in order to further ensure that the smoke can be introduced from the air inlet box 8 into the main body 6, a vent pipe 10 is rotatably installed on the air inlet box 8. The vent pipe 10 has an air inlet hole 11 at a position corresponding to the air inlet box 8, and an air outlet hole 12 at a position corresponding to the main body 6. When the smoke accumulates to a certain concentration in the air inlet box 8, the vent pipe 10 is rotated so as to correspond to the smoke inlet hole 11, and then introduced into the main body 6. The spraying member 32 sprays seawater to the absorbing member 5, wherein the absorbing member may include a sliding frame, which slides along the main body 5, and a plurality of layers of PTFE membranes are arranged in the sliding frame. The seawater is sprayed from above the PTFE membrane and passes through the PTFE membrane. The smoke rises from below the PTFE membrane and passes through the PTFE membrane. The smoke and the seawater form convection, and the smoke is decarbonized by the joint action of the seawater and the PTFE membrane. The seawater treated with the smoke is discharged through the drain 35. In this way, the effect of the overall smoke concentration accumulation is greatly improved, the smoke entering the treatment is ensured to be at a higher concentration, the absorption efficiency of the absorbing member 5 is ensured, and it has extremely high practical value.

[0063] Furthermore, the secondary processing part 2 also includes:

[0064] A plurality of first guide plates 13 are obliquely disposed in the vent pipe 10 and arranged at intervals along the vent pipe 10;

[0065] There are a plurality of second guide plates 14 which are obliquely disposed in the ventilation pipe 10 and arranged at intervals along the ventilation pipe 10 . The first guide plates 13 and the second guide plates 14 form a gas gathering channel 15 , which is used to gather smoke.

[0066] In this embodiment, in order to ensure that the smoke passes through the air outlet 12 from the air inlet 11 at a slower speed, even if the smoke is further accumulated, the present solution is provided with an inclined first guide plate 13 and a second guide plate 14 in the ventilation pipe 10, and the gas gathering channel 15 formed by the inclined arrangement of the two guide plates further gathers the smoke, so that the concentration of the smoke is further improved, which has extremely high practical value.

[0067] Furthermore, the secondary processing part 2 also includes:

[0068] There are two air collecting plates 16, which are hingedly arranged on the vent pipe 10 and located at the air outlet 12. When the air collecting plates 16 rotate, the air outlet 12 is opened or closed;

[0069] There are a plurality of first elastic members 17 , one end of which is disposed on the air collecting plate 16 , and the other end of which is disposed on the vent pipe 10 . The first elastic member 17 is used to provide the air collecting plate 16 with a force to close the air outlet 12 .

[0070] In this embodiment, in order to ensure that the smoke entering the main body 6 reaches a certain volume and concentration, an air gathering plate 16 for blocking the smoke is provided at the air outlet 12 in this scheme. When the smoke enters the ventilation pipe 10 and reaches the elastic limit of the first elastic member 17, the air gathering plate 16 opens to introduce the smoke. In this way, the volume and concentration of the smoke in this scheme are at a constant value during treatment, thereby ensuring the overall treatment effect.

[0071] Furthermore, the secondary processing part 2 also includes:

[0072] The air blocking block 19 is arranged on the main body 6. The air blocking block 19 and the main body 6 form an air guiding groove 18. Both sides of the air guiding groove 18 have openings communicating with the interior of the main body 6. The vent pipe 10 passes through the air blocking block 19 and communicates with the air guiding groove 18.

[0073] There are several air guide modules 20, which are arranged on the main body 6 and located on both sides of the air blocking block 19. After the air guide modules 20 are working, a high flow rate area 21 is formed at the air guide modules 20, and the high flow rate area 21 is used to attract smoke.

[0074] In this embodiment, in order to ensure that the smoke is absorbed and processed by the absorbent 5 in the main body 6, an air blocking block 19 for blocking the flow of gas is provided on the main body 6. Through the air guide groove 18 formed between the air blocking block 19 and the main body 6, the smoke enters the air guide groove 18 after being discharged from the air outlet 12, and then the smoke is dispersedly discharged into the main body 6 through the opening of the air guide groove 18, and further blown to the absorbent 5 under the suction of the high flow rate area 21 formed by the wind guide module 20. In this way, the flow direction of the smoke in this scheme can only be from bottom to top to the absorbent 5, ensuring that its flow path passes through the absorbent 5, that is, ensuring the overall absorption effect, so that the overall absorption rate is further improved, and it has a high practical value.

[0075] Furthermore, the secondary processing part 2 also includes:

[0076] The limit block 22 is arranged in the slide groove 4 in an adjustable position, and is used to limit the sliding of the absorber 5.

[0077] Furthermore, the secondary processing part 2 also includes:

[0078] The blocking plate 24 is slidably disposed in the slide groove 4, and the absorber 5 is used to drive the blocking plate 24 to slide. After the blocking plate 24 slides, it is used to open or close the exhaust port 23;

[0079] There are a plurality of second elastic members 25 , one end of which is disposed on the blocking plate 24 and the other end is disposed on the main body 6 . The second elastic member 25 is used to provide a force for the blocking plate 24 to close the exhaust port 23 .

[0080] In this embodiment, in order to ensure that the smoke in the main body 6 is fully absorbed by the absorber 5 before being discharged, this solution provides a blocking plate 24 at the exhaust port 23 for exhausting the gas. When the volume of the smoke in the main body 6 reaches a certain volume, as the absorber 5 slides, the absorber 5 and the blocking plate 24 drive the blocking plate 24 to move, thereby opening the exhaust port 23 to complete the exhaust operation. In this way, it is ensured that the smoke in the main body 6 is absorbed by the absorber 5 at least once, thereby ensuring the overall absorption effect, so that the overall smoke treatment effect is further improved, and it has extremely high practical value.

[0081] Further, the preliminary processing part 1 includes:
