Description

Technical Field

[0001] The present application relates to the field of gas treatment, and in particular to a deodorization system for harmful gases in a sewage treatment plant. Background Art

[0002] Sewage treatment equipment is an industrial equipment that can effectively treat domestic sewage, industrial wastewater, etc. in urban areas, avoiding the direct inflow of sewage and pollutants into water areas, and is of great significance for improving the ecological environment, enhancing the urban grade, and promoting economic development.

[0003] In the existing sewage treatment, basically the sewage is first introduced into a sewage tank. In order to reduce the dispersion of sewage odor, some sewage tanks are equipped with a lid above the sewage tank, and then operation reserved holes are opened on the lid, and then the required reactants are poured into the sewage tank to treat the sewage. The odor generated by the sewage will be sucked into a professional deodorization device by a deodorization fan for deodorization treatment, and then discharged.

[0004] When the existing sewage odor treatment device treats the odor generated by sewage, when the odor content of the sewage is relatively high, due to the continuous flow of odor, the odor treatment device may discharge the odor before it has time to treat it or before it is completely treated. Summary of the Utility Model

[0005] The purpose of the present application is to: To solve the problem that when the odor content of sewage is relatively high, due to the continuous flow of odor, the odor treatment device may discharge the odor before it has time to treat it or before it is completely treated as mentioned in the above background art, the present application provides a deodorization system for harmful gases in a sewage treatment plant.

[0006] The present application specifically adopts the following technical solutions to achieve the above purpose:

[0007] A deodorization system for harmful gases in a sewage treatment plant includes a biochemical tank. A deodorization device is arranged on one side of the biochemical tank. A first deodorization fan is installed on the deodorization device. A first connecting pipe is fixedly connected between the first deodorization fan and the biochemical tank. A new deodorization mechanism is arranged on one side of the biochemical tank. A waste incineration building is arranged on one side of the new deodorization mechanism. A tank cover sealing mechanism is arranged on the biochemical tank.

[0008] By adopting the above technical solutions, the new deodorization mechanism discharges the odor towards the waste incineration building. When the waste incineration building is incinerating waste, the odor entering the waste incineration building is incinerated. When the waste incineration building is not working, the first deodorization fan can be directly opened to allow the odor to enter the deodorization device for traditional deodorization. Thus, the switching between the original deodorization device and the new deodorization mechanism can be realized, the treatment of the generated odor volume is satisfied, and the harmless and resource-based treatment of the odor is realized.

[0009] Further, the new deodorization mechanism includes a second connecting pipe fixedly connected to the first connecting pipe. One end of the second connecting pipe away from the first connecting pipe is fixedly connected to a second deodorization fan. An electric control butterfly valve I is fixed between the second connecting pipe and the second deodorization fan. One side of the second deodorization fan is fixedly connected to a third connecting pipe.

[0010] By adopting the above technical solution, when the electric control butterfly valve I is opened, the odor in the biochemical tank can be sucked by the second deodorization fan, so that the odor in the biochemical tank can conveniently enter the second connecting pipe and the third connecting pipe.

[0011] Further, a primary air tuyere pipe is fixed on the waste incineration building, and a secondary air tuyere pipe is fixed on the waste incineration building.

[0012] By adopting the above technical solution, the third connecting pipe is connected to the primary air tuyere pipe, so that the odor can enter the waste incineration building. When there is no odor in the third connecting pipe, air can enter through the secondary air tuyere pipe, so that it can be conveniently switched back and forth according to the actual situation.

[0013] Further, an electric control butterfly valve II is fixed between the third connecting pipe and the primary air tuyere pipe.

[0014] By adopting the above technical solution, when the waste incineration building uses the secondary air tuyere pipe to intake air for combustion, the electric control butterfly valve II is closed, so as to reduce the gas from the waste incineration building combustion from entering the third connecting pipe.

[0015] Further, an electric control three-way butterfly valve is fixed between the first connecting pipe, the second connecting pipe and the biochemical tank.

[0016] By adopting the above technical solution, the electric control three-way butterfly valve is used to change the connection between the biochemical tank and the first connecting pipe and the second connecting pipe, so that the odor in the biochemical tank can be conveniently switched between the first connecting pipe and the second connecting pipe.

[0017] Further, the connections of the first connecting pipe, the second connecting pipe and the third connecting pipe are all connected by flanges, and the first connecting pipe, the second connecting pipe and the third connecting pipe are all integrally formed pipes.

[0018] By adopting the above technical solution, the first connecting pipe, the second connecting pipe and the third connecting pipe are hermetically connected by flanges and integrally formed, so as to reduce the possibility of odor overflow during transportation and reduce the possibility of air leakage.

[0019] Further, the pool cover sealing mechanism includes a sealing cover arranged on the biochemical tank. A sealing frame is fixed on the biochemical tank, and a water filling groove is opened on the sealing frame.

[0020] By adopting the above technical solution, the sealing cover is placed on the sealing frame, and then water is poured into the water filling tank on the sealing frame. The edge of the sealing cover is submerged by water, and the water blocks the air, so as to reduce the possibility that when the sealing cover is placed on the biochemical tank, odor escapes from the gap between the sealing cover and the biochemical tank.

[0021] Further, an airbag is fixed on the inner wall of the water filling tank. The airbag is annular along the inner wall of the water filling tank. An air pump is fixed on one side of the sealing frame, and the air pump is communicated with the airbag.

[0022] By adopting the above technical solution, the airbag is inflated by the air pump, and the airbag abuts against the sealing cover, so as to further seal the sealing cover.

[0023] In summary, the present application includes at least one of the following beneficial effects;

[0024] 1. In the present application, when the waste incineration building is working, the biochemical tank is connected to the second connecting pipe by using the electric control three-way butterfly valve, and the connection between the biochemical tank and the first connecting pipe is closed. Then, the first electric control butterfly valve and the second electric control butterfly valve are opened, and the deodorizing fan II is made to work. The deodorizing fan extracts the odor in the biochemical tank through the second connecting pipe, and then sends the odor to the primary air tuyere pipe through the third connecting pipe. Then, the odor enters the working waste incineration building, and the odor is incinerated and treated. When the waste incineration building is not working, the biochemical tank is connected to the first connecting pipe by using the electric control three-way butterfly valve, so that the odor enters the deodorizing device for treatment. Or when the odor in the biochemical tank cannot support the work of the waste incineration building, air is introduced into the waste incineration building through the secondary air tuyere pipe, and the second electric control butterfly valve is closed to close the connection between the primary air tuyere pipe and the third connecting pipe, reducing the incinerated gas from entering the third connecting pipe, achieving the purpose of meeting the treatment of the generated odor volume and improving the effect of harmless and resourceful treatment of the odor.

[0031] The following further elaborates on this application Figures 1-3 in conjunction with the accompanying drawings

[0032] The embodiment of this application discloses a harmful gas deodorization system for a sewage treatment plant

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , a harmful gas deodorization system for a sewage treatment plant includes a biochemical tank 1. A deodorizing device 4 is arranged on one side of the biochemical tank 1. A first deodorizing fan 2 is installed on the deodorizing device 4. A first connecting pipe 3 is fixedly connected between the first deodorizing fan 2 and the biochemical tank 1. A new deodorizing mechanism 5 is arranged on one side of the biochemical tank 1. A waste incineration building 7 is arranged on one side of the new deodorizing mechanism 5. A tank cover sealing mechanism 6 is arranged on the biochemical tank 1

[0034] When the sewage treatment plant treats sewage, first the sewage is drained into the biochemical tank 1, then the tank cover sealing mechanism 6 is opened, a reactant is poured into the sewage, and then the tank cover sealing mechanism 6 seals the biochemical tank 1. When the first deodorizing fan 2 is not turned on, the odor enters the new deodorizing mechanism 5 through the first connecting pipe 3, and the new deodorizing mechanism 5 discharges the odor to the waste incineration building 7. When the waste incineration building 7 is incinerating waste, the odor entering the waste incineration building 7 is incinerated. When the waste incineration building 7 is not working, the first deodorizing fan 2 can be directly turned on to allow the odor to enter the deodorizing device 4 for traditional deodorization. By using the new deodorizing mechanism 5 to send the odor generated by the biochemical tank 1 to the waste incineration building 7, and the waste incineration building 7 incinerates the odor, the switching between the original deodorizing device 4 and the new deodorizing mechanism 5 can be realized, meeting the treatment of the generated odor volume, and realizing the harmless and resourceful treatment of the odor

[0035] Referring to Figure 1 , Figure 2 and Figure 3, the new deodorization mechanism 5 includes a second connecting pipe 51 fixedly connected to the first connecting pipe 3. One end of the second connecting pipe 51 far from the first connecting pipe 3 is fixedly connected to a second deodorization fan 53. An electric control butterfly valve 52 is fixed between the second connecting pipe 51 and the second deodorization fan 53. One side of the second deodorization fan 53 is fixedly connected to a third connecting pipe 54.

[0036] In addition, a primary air tuyere pipe 56 is fixed on the waste incineration building 7, and a secondary air tuyere pipe 57 is fixed on the waste incineration building 7.

[0037] Moreover, an electric control butterfly valve 58 is fixed between the third connecting pipe 54 and the primary air tuyere pipe 56.

[0038] And, an electric control three-way butterfly valve 59 is fixed between the first connecting pipe 3, the second connecting pipe 51 and the biochemical pool 1.

[0039] When the waste incineration building 7 is working, the electric control three-way butterfly valve 59 is used to connect the biochemical pool 1 with the second connecting pipe 51, and the connection between the biochemical pool 1 and the first connecting pipe 3 is closed. Then the electric control butterfly valve 52 and the electric control butterfly valve 58 are opened to make the second deodorization fan 53 work. The deodorization fan extracts the odor in the biochemical pool 1 through the second connecting pipe 51, and then sends the odor to the primary air tuyere pipe 56 through the third connecting pipe 54. Then the odor enters the working waste incineration building 7 and is incinerated. When the waste incineration building 7 is not working, the electric control three-way butterfly valve 59 is used to connect the biochemical pool 1 with the first connecting pipe 3 to let the odor enter the deodorization device 4 for treatment. Or when the odor in the biochemical pool 1 cannot support the work of the waste incineration building 7, the secondary air tuyere pipe 57 is used to supply air to the waste incineration building 7, and the electric control butterfly valve 58 is closed to close the connection between the primary air tuyere pipe 56 and the third connecting pipe 54, reducing the entry of incinerated gas into the third connecting pipe 54. By using the cooperation of the electric control three-way butterfly valve 59, the electric control butterfly valve 52, and the electric control butterfly valve 58, the odor in the biochemical pool 1 can be switched between the deodorization device 4 and the waste incineration building 7, thus meeting the treatment of the generated odor volume and improving the effect of odor harmless and resource treatment.

[0040] Refer to Figure 1 and Figure 2 , the connections of the first connecting pipe 3, the second connecting pipe 51, and the third connecting pipe 54 are all connected by flanges. The first connecting pipe 3, the second connecting pipe 51, and the third connecting pipe 54 are all integrally formed pipes. When transporting odor using the first connecting pipe 3, the second connecting pipe 51, and the third connecting pipe 54, the connections of the first connecting pipe 3, the second connecting pipe 51, and the third connecting pipe 54 are all sealed and connected using connecting flanges, and the first connecting pipe 3, the second connecting pipe 51, and the third connecting pipe 54 are integrally formed without gaps on the pipes. By making the first connecting pipe 3, the second connecting pipe 51, and the third connecting pipe 54 be sealed and connected by flanges and integrally formed, the possibility of odor overflow during transportation can be reduced, and the possibility of air leakage can be reduced.

[0041] Refer to Figure 2 and Figure 3 Figure 3 , the pool cover sealing mechanism 6 includes a sealing cover 61 arranged on the biochemical pool 1. There is a sealing frame 62 on the fixed rod of the biochemical pool 1, and a water filling groove 63 is opened on the sealing frame 62.

[0042] In addition, an airbag 64 is fixed on the inner wall of the water filling groove 63. The airbag 64 is annular along the inner wall of the water filling groove 63. An air inflation pump 65 is fixed on one side of the sealing frame 62, and the air inflation pump 65 is communicated with the airbag 64.

[0043] When adjusting the high and low concentrations of the sewage in the biochemical pool 1, remove the sealing cover 61 from the sealing frame 62, and then adjust through the hole on the biochemical pool 1. After the adjustment is completed, cover the sealing cover 61 on the sealing frame 62, and then fill the water filling groove 63 on the sealing frame 62 with water. Use the water to cover the edge of the sealing cover 61 to block the air. Then use the air inflation pump 65 to inflate the airbag 64 to make the airbag 64 abut against the sealing cover 61 to further seal the sealing cover 61. By placing the sealing cover 61 into the sealing frame 62, then using the water to cover the edge of the sealing cover 61, and at the same time using the airbag 64 to squeeze the sealing cover 61, it is possible to reduce the possibility that when the sealing cover 61 covers the biochemical pool 1, odor escapes from the gap between the sealing cover 61 and the biochemical pool 1.

[0044] Working principle: When the sewage treatment station treats sewage, first discharge the sewage to the biochemical pool 1. When adjusting the high and low concentrations of the sewage in the biochemical pool 1, remove the sealing cover 61 from the sealing frame 62, and then adjust through the hole on the biochemical pool 1. After the adjustment is completed, cover the sealing cover 61 on the sealing frame 62, and then fill the water filling groove 63 on the sealing frame 62 with water. Use the water to cover the edge of the sealing cover 61 to block the air. Then use the air inflation pump 65 to inflate the airbag 64 to make the airbag 64 abut against the sealing cover 61 to further seal the sealing cover 61. When the waste incineration building 7 is working, use the electric control three-way butterfly valve 59 to connect the biochemical pool 1 with the connecting pipe two 51, close the connection between the biochemical pool 1 and the connecting pipe one 3, and then open the electric control butterfly valve one 52 and the electric control butterfly valve two 58 to make the deodorizing fan two 53 work. The deodorizing fan extracts the odor in the biochemical pool 1 through the connecting pipe two 51, and then sends the odor to the primary air tuyere pipe 56 through the connecting pipe three 54. Then the odor enters the working waste incineration building 7 and is incinerated. When the waste incineration building 7 is not working, use the electric control three-way butterfly valve 59 to connect the biochemical pool 1 with the connecting pipe one 3 to allow the odor to enter the deodorizing device 4 for treatment.
