Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization and denitration equipment, and in particular to integrated desulfurization and denitration treatment equipment for treating incineration waste gas. Background Art

[0002] In people's daily life, it is inevitable to generate a lot of garbage. If these garbage are not effectively processed, it will greatly affect people's living environment and even threaten people's health.

[0003] Waste incineration power generation is an advanced waste treatment method that effectively converts chemical energy in municipal waste into electrical energy by subjecting municipal waste to thermal treatment at high temperatures. This process not only reduces the volume and weight of waste, but also generates usable energy, which is of great significance for municipal waste management and energy recovery. The waste is first sent to the incinerator, where it is fully oxidized and burned in a high-temperature environment, which greatly reduces the volume of domestic waste and produces a small amount of stable residue. At the same time, the heat can be used to generate electricity. A large amount of waste gas will be generated during the incineration process of waste, which contains a large amount of pollutants, mainly smoke, nitrogen oxides and sulfur dioxide. As the country pays more and more attention to air pollution control, the waste gas generated by incineration of waste needs to be treated with desulfurization and denitrification equipment before being discharged.

[0004] There are two types of waste gas desulfurization and denitrification processes: dry and wet. Dry desulfurization and denitrification processes are commonly used. The dry desulfurization and denitrification process is simple, has no sewage and waste acid treatment problems, and has low energy consumption.

[0005] The existing desulfurization and denitrification equipment has gradually exposed its shortcomings during use, mainly in the following aspects:

[0006] First, the exhaust gas is not fully mixed with ammonia and the catalyst during the dry denitrification process, resulting in a slow denitrification speed, poor denitrification effect, and serious catalyst waste, which increases the cost of exhaust gas treatment. Specifically, dry denitrification refers to mixing the exhaust gas after desulfurization and dust removal with ammonia under the catalysis of the catalyst. The nitrogen oxides in the exhaust gas react with ammonia to generate nitrogen and water. During the denitrification process, the atomized catalyst and ammonia are respectively sprayed into the exhaust gas after desulfurization and dust removal. After the catalyst and ammonia are sprayed out, they flow along the flow direction of the exhaust gas. During the flow, the catalyst and ammonia cannot be fully mixed with the exhaust gas. Therefore, the denitrification speed of the exhaust gas is slow and the denitrification effect is poor. In addition, during the denitrification process, the sprayed catalyst catalyzes the reaction of ammonia and nitrogen oxides, and is finally discharged to the outside of the equipment with the treated gas. Therefore, a large amount of catalyst will be wasted in the process of exhaust gas denitrification, which increases the cost of exhaust gas treatment.

[0007] Second, the waste gas treatment equipment has a single function, and the dust removal equipment needs to be shut down and cleaned regularly, which affects the treatment of waste gas. Specifically, during the waste gas treatment process, it is necessary to successively pass through desulfurization equipment, dust removal equipment and denitrification equipment for desulfurization, dust removal and denitrification respectively. The same equipment can only perform a single treatment process on waste gas. Therefore, the equipment has a single function, and the dust removal equipment needs to be regularly cleaned from the smoke adsorbed on the filter component during use. The cleaning requires shutdown operation, which affects the treatment of waste gas.

[0008] Third, when adding desulfurizer to the exhaust gas during dry desulfurization, the distribution is uneven, and the content of desulfurizer in the exhaust gas is uneven, resulting in poor desulfurization effect on the exhaust gas. Specifically, during the desulfurization process, the desulfurizer powder needs to be sprayed into the flowing exhaust gas at high pressure. The powder will move to one side of the exhaust gas under the action of inertia, and the spray range of the powder cannot completely cover the passing exhaust gas. The above two situations together lead to uneven distribution of the desulfurizer in the exhaust gas, which in turn leads to poor desulfurization effect on the exhaust gas.

[0009] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0010] In view of the defects in the prior art, the technical problem to be solved by the present invention is to provide an integrated desulfurization and denitrification treatment device for incineration waste gas treatment, in which ammonia and a catalyst can be fully mixed with the waste gas during the denitrification process of the waste gas, thereby improving the denitrification speed and denitrification effect of the waste gas, and can also greatly reduce the waste of the catalyst and reduce the treatment cost of the waste gas;

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. When desulfurizing the incineration waste gas, the servo motor drives the driven shaft to rotate, and then drives the rotating circular plate and the stirring blades to rotate. Under the extraction of the air pump, the waste gas enters the desulfurization tank through the air inlet pipe and flows upward. The waste gas enters the mixing tube through the circular groove and the storage hole in turn. During the rotation of the rotating circular plate, the desulfurizer between the upper supporting circular plate and the lower supporting circular plate enters the storage hole. When the storage hole containing the desulfurizer rotates to the top of the circular groove, the waste gas can blow the desulfurizer into the mixing tube during the process of passing through the storage hole. Under the blowing of the waste gas, the desulfurizer is dispersed and mixed with the waste gas. After the desulfurizer and the waste gas are discharged from the mixing tube, the stirring blades can stir and mix the waste gas and the desulfurizer discharged from multiple mixing tubes. During the rotation of the rotating circular plate, the desulfurizer can be evenly added to the waste gas, and under the stirring of the stirring blades, the desulfurizer in the waste gas is evenly distributed, thereby improving the desulfurization effect of the waste gas.

[0035] 2. During the rotation of the rotating circular plate, the reciprocating telescopic cylinder can drive the lifting ring and the scattering plate to lift and lower vertically. The scattering plate can move the desulfurizer between the upper supporting circular plate and the lower supporting circular plate to prevent the desulfurizer from accumulating and ensure that the desulfurizer powder enters the storage hole;

[0036] 3. After desulfurization, the exhaust gas enters the denitrification box through the external exhaust pipe. When the exhaust gas passes through the dust filter cartridge, the smoke in it can be filtered. The filtered exhaust gas can be directly denitrified. When the outer wall of the dust filter cartridge absorbs more smoke, the control motor drives the control gear to rotate, and then drives the driven gear ring, the driven ring and the cleaning brush to rotate. The cleaning brush can clean the smoke adsorbed on the outer wall of the dust filter cartridge. The cleaned smoke falls into the dust collecting hopper for collection. The equipment integrates dust removal and denitrification functions, realizing the diversification of equipment functions. At the same time, it also realizes the function of automatically cleaning the smoke adsorbed on the outer wall of the dust filter cartridge without stopping the machine, which improves the practicality of the equipment.

[0037] 4. When denitrifying the exhaust gas after dust removal, the water pump draws the catalyst in the fixed cylinder into the liquid inlet cylinder. The catalyst in the liquid inlet cylinder flows upward and enters the liquid distribution box through the rotating tube and the liquid pipe in turn, and is finally discharged from the drainage hole. At the same time, the internal drive motor drives the internal drive gear and the internal driven gear to rotate, and then drives the rotating tube, the liquid pipe, the liquid distribution box and the support tube to rotate, so that the catalyst can be evenly applied to the surface of the liquid absorbent cotton. The external drive motor drives the external drive gear and the external driven gear to rotate, and then drives the rotating tube, the air inlet cylinder, the sealing tube and the air distribution tube to rotate, and the dust is removed through the dust filter cartridge. When the exhaust gas after dust removal passes through the air distribution pipe, ammonia from the external ammonia source enters the transition tube through the ventilation pipe, and enters the air intake tube through the rotating pipe, and is finally discharged from the exhaust hole to the air distribution pipe to mix with the exhaust gas. Through the set air distribution pipes, the ammonia discharged from the exhaust hole can be fully mixed with the exhaust gas when the exhaust gas after dust removal passes through the air distribution pipe. During the rotation of the air intake tube, the mixed gas can be sprayed to different areas of the liquid absorbent cotton. The mixed gas can be fully contacted with the catalyst when passing through the liquid absorbent cotton, thereby realizing the function of fully mixing and contacting the exhaust gas with the ammonia and the catalyst, and improving the denitration speed and denitration effect of the exhaust gas.

[0038] 5. Under the extraction of the water pump, the catalyst in the fixed cylinder can be continuously applied to the absorbent cotton. As the amount of catalyst in the absorbent cotton increases, the catalyst in the absorbent cotton flows downward until the catalyst detaches from the bottom of the absorbent cotton and drips into the fixed cylinder. Therefore, the catalyst in the fixed cylinder can circulate through the absorbent cotton and catalyze the reaction of the mixed gas passing through the absorbent cotton. The mixed gas takes away very little catalyst when passing through the absorbent cotton, thereby greatly reducing the consumption of the catalyst and reducing the cost of gas treatment.

[0054] The denitration mechanism 7 includes a horizontally fixed support cylinder 26, both ends of the support cylinder 26 are sealed, a fixed cylinder 27 with both ends sealed is coaxially fixed on the top of the support cylinder 26, a closed tube 28 is coaxially arranged in the fixed cylinder 27, the top and bottom of the closed tube 28 pass through the fixed cylinder 27 respectively, and are flush with the top and bottom of the fixed cylinder 27, a rotating tube 40 is coaxially arranged on the top of the support cylinder 26, the upper port of the rotating tube 40 is sealed, and a liquid inlet cylinder 41 with an open top is coaxially fixed to the inner top of the support cylinder 26, the lower port of the rotating tube 40 passes through the support cylinder 26 and extends into the liquid inlet cylinder 41, and is rotatably sealed with the liquid inlet cylinder 41. The inner bottom of the liquid inlet cylinder 41 is coaxially fixed with a support rod 46, the top of the support rod 46 passes through the rotating tube 40 upward, and is coaxially fixed with an inner exhaust pipe 34 with a sealing bottom. The support rod 46 is rotatably sealed and connected with the rotating tube 40. The outer wall of the inner exhaust pipe 34 is fixedly sleeved with a coaxially arranged fixed circular plate 32. The outer wall of the inner exhaust pipe 34 is located below the fixed circular plate 32 and is uniformly distributed along the circumferential direction with a plurality of exhaust grooves 33 that are penetrated. The top of the fixed cylinder 27 is penetrated with an annular groove 29. The inner wall of the annular groove 29 and the bottom of the fixed circular plate 32 are coaxially fixed with an inner support ring 35. The circumferential walls of the two inner support rings 35 are paved with the same liquid absorbent cotton 30.

[0055] A rotatable support tube 36 is coaxially arranged between the two inner support rings 35. The outer diameter of the support tube 36 is the same as that of the inner support rings 35, and the top and bottom of the support tube 36 are in frictional contact with the two inner support rings 35. A plurality of vertically arranged liquid distribution boxes 38 are evenly distributed in the circumferential direction in the support tube 36. One end of the liquid distribution box 38 is open and fixed to the inner wall of the support tube 36. A plurality of drainage holes 39 are evenly distributed on the inner wall of the support tube 36 at a position inside the liquid distribution box 38. The inner wall of the support tube 36 is located between two adjacent liquid distribution boxes 38. A plurality of ventilation grooves 37 are evenly distributed along the axial direction, and a plurality of liquid pipes 45 connected to the inner cavity of the liquid distribution box 38 are evenly distributed vertically at one end thereof. One end of the liquid pipe 45 is fixedly connected to the outer wall of the rotating tube 40 and is connected to the inner cavity of the rotating tube 40. A water pump 48 is fixedly provided on the inner top of the support cylinder 26. The water inlet and the drain port of the water pump 48 are both fixedly connected to connecting pipes 47 that are connected. One of the connecting pipes 47 is connected to the inner cavity of the liquid inlet cylinder 41, and the other connecting pipe 47 passes through the support cylinder 26 and is connected to the inner cavity of the fixed cylinder 27.

[0056] The top of the support cylinder 26 is also provided with a dust removal component 5 for removing dust from the exhaust gas after desulfurization, and the bottom of the sealing plate 9 is provided with an air distribution component 8 connected to the external ammonia source.

[0057] The exhaust gas after desulfurization by the desulfurization mechanism 15 enters the denitrification box 4, and the smoke in the exhaust gas can be filtered by the dust removal component 5. The exhaust gas after dust removal can be fully mixed with the ammonia gas sprayed by the air distribution component 8 when passing through the air distribution component 8. The water pump 48 extracts the catalyst in the fixed cylinder 27 into the liquid inlet cylinder 41. The catalyst in the liquid inlet cylinder 41 flows upward and enters the liquid distribution box 38 through the rotating tube 40 and the liquid passing pipe 45 in turn, and is finally discharged from the drainage hole 39. At the same time, the rotating tube 40 drives the liquid passing pipe 45, the liquid distribution box 38 and the support tube 36 to rotate, so that the catalyst can be evenly applied to the surface of the absorbent cotton 30. The mixed gas of the exhaust gas after dust removal and ammonia gas is When passing through the absorbent cotton 30, the gas can fully contact with the catalyst. The treated gas enters the support tube 36 through the ventilation groove 37, and enters the internal exhaust pipe 34 through the exhaust groove 33, and is finally discharged to the outside by the gas distribution component 8. As the amount of catalyst coating increases, the catalyst in the absorbent cotton 30 flows downward until the catalyst detaches from the bottom of the absorbent cotton 30 and drips into the fixed cylinder 27.

[0078] The denitration box 4 is dragged through a number of support blocks 2 and fixedly connected to the support base 1 .

[0079] The working principle of this device is:

[0080] When the incineration waste gas is desulfurized, the servo motor 11 drives the driven shaft 12 to rotate, and then drives the rotating circular plate 23 and the stirring blade 14 to rotate. Under the extraction of the air pump 21, the waste gas enters the desulfurization tank 13 through the air inlet pipe 22 and flows upward. The waste gas enters the mixing tube 18 through the circular groove 72 and the storage hole 24 in turn. During the rotation of the rotating circular plate 23, the desulfurizer between the upper supporting circular plate 16 and the lower supporting circular plate 20 enters the storage hole 24. When the storage hole 24 containing the desulfurizer rotates to the circular groove 72, the desulfurizer between the upper supporting circular plate 16 and the lower supporting circular plate 20 enters the storage hole 24. When the exhaust gas passes through the storage hole 24, the desulfurizer can be blown into the mixing tube 18. Under the blowing of the exhaust gas, the desulfurizer is dispersed and mixed with the exhaust gas. After the desulfurizer and the exhaust gas are discharged from the mixing tube 18, the stirring blade 14 can stir and mix the exhaust gas and the desulfurizer discharged from the multiple mixing tubes 18. The desulfurizer can be evenly added to the exhaust gas during the rotation of the rotating circular plate 23. Under the stirring of the stirring blade 14, the desulfurizer in the exhaust gas is evenly distributed, thereby improving the desulfurization effect of the exhaust gas.

[0081] During the rotation of the rotating circular plate 23, the reciprocating telescopic cylinder 69 can drive the lifting ring 74 and the scattering plate 73 to vertically reciprocate and lift, and the scattering plate 73 can move the desulfurizer between the upper supporting circular plate 16 and the lower supporting circular plate 20 to prevent the desulfurizer from accumulating and ensure that the desulfurizer powder enters the storage hole 24;

[0082] The exhaust gas after desulfurization enters the denitrification box 4 through the external exhaust pipe 10. When the exhaust gas passes through the dust filter cartridge 31, the smoke therein can be filtered. The filtered exhaust gas can be directly subjected to denitrification treatment. When the outer wall of the dust filter cartridge 31 adsorbs more smoke, the control motor 68 drives the control gear 67 to rotate, thereby driving the driven gear ring 65, the driven ring 64 and the cleaning brush 63 to rotate. The cleaning brush 63 can clean the smoke adsorbed on the outer wall of the dust filter cartridge 31. The cleaned smoke falls into the dust collecting hopper 3 for collection. The equipment integrates dust removal function and denitrification function, realizes the diversification of equipment functions, and also realizes the function of automatically cleaning the smoke adsorbed on the outer wall of the dust filter cartridge 31 without stopping the machine, thereby improving the practicality of the equipment.

[0083] When denitrifying the exhaust gas after dust removal, the water pump 48 draws the catalyst in the fixed cylinder 27 into the liquid inlet cylinder 41. The catalyst in the liquid inlet cylinder 41 flows upward and enters the liquid distribution box 38 through the rotating tube 40 and the liquid passing tube 45 in turn, and is finally discharged from the drainage hole 39. At the same time, the internal drive motor 42 drives the internal drive gear 43 and the internal driven gear 44 to rotate, and then drives the rotating tube 40, the liquid passing tube 45, the liquid distribution box 38 and the support tube 36 to rotate, so that the catalyst can be evenly applied to the surface of the liquid absorbent cotton 30. The external drive motor 56 drives the external drive gear 58 and the external driven gear 52 to rotate, and then drives the rotating tube 57, the air inlet cylinder 49, the sealing tube 60 and the air distribution tube 62 to rotate. When the exhaust gas after dust removal by the dust removal filter 31 passes through the air distribution pipe 62, the ammonia from the external ammonia source enters the transition tube 55 through the ventilation pipe 53, and enters the air intake tube 49 through the rotating tube 57, and is finally discharged from the exhaust hole 61 to the air distribution pipe 62 to mix with the exhaust gas. Through the set several air distribution pipes 62, when the exhaust gas after dust removal passes through the air distribution pipe 62, the ammonia discharged from the exhaust hole 61 can be fully mixed with the exhaust gas. During the rotation of the air intake tube 49, the mixed gas can be sprayed to different areas of the liquid absorbent cotton 30. The mixed gas can be fully contacted with the catalyst when passing through the liquid absorbent cotton 30, thereby realizing the function of fully mixing and contacting the exhaust gas with the ammonia and the catalyst, and improving the denitration speed and denitration effect of the exhaust gas.

[0084] Under the extraction of the water pump 48, the catalyst in the fixed cylinder 27 can be continuously applied to the liquid absorbent cotton 30. As the amount of catalyst in the liquid absorbent cotton 30 increases, the catalyst in the liquid absorbent cotton 30 flows downward until the catalyst detaches from the bottom of the liquid absorbent cotton 30 and drips into the fixed cylinder 27. Therefore, the catalyst in the fixed cylinder 27 can circulate through the liquid absorbent cotton 30 and catalyze the reaction of the mixed gas passing through the liquid absorbent cotton 30. The mixed gas takes away very little catalyst when passing through the liquid absorbent cotton 30, thereby greatly reducing the consumption of the catalyst and reducing the cost of gas treatment.

[0085] The processed gas enters the support pipe 36 through the ventilation groove 37 and enters the inner exhaust pipe 34 through the exhaust groove 33. The gas in the inner exhaust pipe 34 flows upward and is discharged to the outside through the limiting pipe 54 for subsequent processing.
