[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses an environmentally friendly pipeline spray deodorizing device.

[0030] Reference Figure 1 The environmentally friendly pipeline spray deodorizing device comprises a purification pipeline 1, a spray mechanism 2, a detection mechanism 4, and a control cabinet 5, wherein the control cabinet 5 is integrated with an alarm; the purification pipeline 1 comprises a pipeline 11 and a fan 12, the pipeline 11 comprises a main deodorizing section 13, a secondary deodorizing section 14, a tail gas section 15 and a bypass pipeline 16, wherein one end of the main deodorizing section 13 is an air inlet end, the other end of the main deodorizing section 13 is connected to the secondary deodorizing section 14, the other end of the secondary deodorizing section 14 is connected to the tail gas section 15, the two ends of the secondary deodorizing section 14 are also connected to the two ends of the bypass pipeline 16, the other end of the tail gas section 15 is an air outlet end, and the air outlet end is connected to a chimney; the fan 12 is installed at the connection between the secondary deodorizing section 14 and the tail gas section 15, and the fan 12 and the spray mechanism 2 are electrically connected to the control cabinet 5 respectively.

[0031] Fillers are placed in both the primary deodorization section 13 and the secondary deodorization section 14. The fillers may be a mixture of ceramsite and carbon, and the diameter of the fillers may be 70-80% of the diameter of the pipe 11, which is more conducive to the full reaction of the fillers with the odor.

[0032] Reference Figure 1 and Figure 2The spray mechanism 2 includes a first spray unit 21, a second spray unit 22 and a deodorant liquid storage tank 23. The position of the first spray unit 21 corresponds to the main deodorization section 13, and the position of the second spray unit 22 corresponds to the secondary deodorization section 14. The first spray unit 21 and the second spray unit 22 include a plurality of spray heads and a liquid supply pipe. The first valve 18, the second valve 19 and the one-way valve 17 are installed in the pipeline 11. The one-way valve 17 is installed at one end of the main deodorization section 13 connected to the secondary deodorization section 14, and the one-way valve 17 is installed at one end of the bypass pipeline 16 connected to the secondary deodorization section 14 and close to the main deodorization section 13. The one-way valve 17 located in the bypass pipeline 16 is used to allow the gas to flow from the bypass pipeline 16 to the secondary deodorization section 14. The first valve 18 is installed at the place where the secondary deodorization section 14 is connected to the tail gas section 15, and the second valve 19 is installed at the place where the bypass pipeline 16 is connected to the secondary deodorization section 14.

[0033] Reference Figure 2 The detection mechanism 4 includes a first gas detector 41, a second gas detector 42, a third gas detector 43 and a wind speed detector. The first gas detector 41 is installed at the air inlet end of the pipeline 11, the second gas detector 42 is installed at the connecting point of the main deodorization section 13 and the secondary deodorization section 14, the third gas detector 43 is installed on the side of the fan 12, and the wind speed detector is installed on the other side of the fan 12. The second gas detector 42 and the third gas detector 43 are respectively integrated with gas alarms, which are located outside the pipeline 11 and can be sound alarms.

[0034] The first spray unit 21, the second spray unit 22, the wind speed detector, the first gas detector 41, the second gas detector 42 and the third gas detector 43 are electrically connected to the control cabinet 5 respectively. The control cabinet 5 is configured as follows:

[0035] If the gas parameter (such as ammonia concentration) fed back by the first gas detector 41 reaches G1, the first spray unit 21 is operated and the fan 12 is operated at the first wind speed; wherein G1 and the first wind speed are preset values, and the first wind speed is less than the initial wind speed of the fan 12;

[0036] If the gas parameter fed back by the second gas detector 42 or the third gas detector 43 is greater than G2, the fan 12 is operated at the second wind speed; wherein G2 and the second wind speed are preset values, and the second wind speed is greater than the first wind speed, the second wind speed is the initial wind speed, and G2 is less than G1;

[0037] If the gas alarm on the second gas detector 42 or the third gas detector 43 sounds an alarm, the fan 12 is operated at the first wind speed, and the second spray unit 22 is commanded to operate.

[0038] Among them, the first wind speed can be called low wind speed, and the low wind speed can be within 0.05mm / s. Let the gas flow at a low wind speed so that the odor can react better with the filler; the initial wind speed can be 0.08m / s-0.12m / s. Let the gas flow at the initial wind speed so that the second gas detector 42 and the third gas detector 43 can detect gas parameters more accurately.

[0039] The first valve 18 and the second valve 19 are respectively connected to the control cabinet 5, and the control cabinet 5 is configured as follows:

[0040] If an alarm signal output by the gas alarm on the second gas detector 42 is received, the first valve 18 and the second valve 19 are closed;

[0041] If an alarm signal output by the gas alarm on the third gas detector 43 is received, the first valve 18 is closed and the second valve 19 is opened;

[0042] If no alarm signal is received, the first valve 18 is commanded to open, the second valve 19 is commanded to close, and the second spray unit 22 is commanded to stop spraying.

[0043] If the gas alarm on the second gas detector 42 sounds an alarm, it means that the odor removal work has not been completed after the spraying of the main deodorization section 13, and an alarm is needed to remind the control cabinet 5 to command the secondary deodorization section 14 to start working. If the gas alarm on the third gas detector 43 still sounds an alarm, the control cabinet 5 needs to command the second valve 19 to open and the first valve 18 to close, so that the odor circulates in the secondary deodorization section 14 and the bypass pipe 16 until the deodorization work is completed, and then the first valve 18 is closed and the second valve 19 is opened to allow the deodorized gas to flow out through the tail gas section 15.

[0044] Reference Figure 3 and Figure 4 The main deodorization section 13 includes a pipe 11 body and a disassembly assembly 3. The main deodorization section 13 and the secondary deodorization section 14 have the same structure. A notch is provided in the pipe wall of the pipe 11 body where the spray port is located, and the disassembly assembly 3 can be detachably connected to the pipe 11 body and fits the notch.

[0045] The disassembly and assembly component 3 includes a tube wall plate 31 detachably connected by bolts. The installation of the tube wall plate 31 facilitates the replacement of fillers. The tube wall plate 31 is arc-shaped and a rubber pad is fixed on the edge. By squeezing the rubber pad, the gap between the pipeline 11 and the tube wall plate 31 can be reduced to reduce air leakage. Baffles 32 are vertically connected to the inner sides of both ends of the tube wall plate 31. One baffle 32 is detachable and can be fixed by a slot or by bolts and nuts. An outlet pipe 35 for draining water is installed on the baffle 32. The outlet pipe 35 can be a corrugated pipe. The corrugated pipe extends through a through hole opened on the pipe body. A liquid level gauge is installed on the side wall of the other baffle 32 facing the tube wall plate 31. The liquid level gauge is electrically connected to the control cabinet.

[0046] The upper halves of the two baffles 32 are hollowed out, and the lower halves are sealed. The baffles 32 can reduce the spillage of fillers due to shaking during disassembly. The hollowing out of the upper half of the baffles 32 allows gas to circulate, and the sealing of the lower half can effectively slow down the flow of the sprayed liquid along the pipeline 11; the above-mentioned liquid level meter is electrically connected to the control cabinet 5, and the liquid level meter can measure the water level information on the tube wall plate 31 and feed it back to the control cabinet 5. After the control cabinet 5 receives the feedback signal of the liquid level meter, if the real-time liquid level is greater than the preset upper limit of the liquid level, the control alarm will sound an alarm to remind that the tube wall plate 31 should be removed, the liquid on the tube wall plate 31 should be poured out, or the spraying speed should be reduced.

[0047] The water outlet pipe 35 penetrates through a matching through hole on the pipe body 11 and extends outward to allow the spray liquid to flow out of the pipe body 11; the water outlet pipe 35 adopts a bellows structure so as to avoid obstacles when disassembling and moving structures such as the pipe wall plate 31.

[0048] Reference Figure 3 and Figure 4 A lifting platform 33 is provided below the pipeline 11, and a screw slide 34 is installed on the top of the lifting platform 33. The sliding direction of the screw slide 34 is parallel to the flow direction of the gas in the upper pipeline 11. Both ends of the tube wall plate 31 are hinged on the slide block, and a lifting unit (not shown in the figure) is installed on the slide block at one end. The lifting unit can be an electric cylinder;

[0049] When the tube wall plate 31 needs to be removed, the lifting platform 33 can be lowered after the bolts are unscrewed, thereby driving the tube wall plate 31 to move downward, and then the tube wall plate 31 is moved to the bottom of the pipe 11 through the screw slide 34. The lifting platform 33 and the screw slide 34 can reduce the shaking and tilting during disassembly, and reduce the spillage of fillers and liquids. When the tube wall plate 31 is moved to the bottom of the pipe 11, one end of the tube wall plate 31 can be pushed up by the lifting unit, thereby tilting the tube wall plate 31 and pouring out the accumulated spray liquid through the outlet pipe, thereby removing the accumulated spray liquid.

[0050] Reference Figure 2 and Figure 4The air inlet end of the pipe 11 is provided with a filter assembly 6, which includes a filter sheet 61, a dust box 62, and a dust brush 63. The filter sheet 61 is installed in the pipe 11 with the same central axis and fits the inner wall of the pipe 11. The filter sheet 61 can be connected by bolts; the dust brush 63 passes through the pipe wall, and the bristles of the dust brush 63 fit the filter sheet 61. A cylinder 64 is installed at the bottom of the pipe 11, and the telescopic rod end of the cylinder 64 is connected to the brush handle of the dust brush 63. The dust box 62 is connected to the lower end of the pipe 11, and the pipe 11 is connected to the dust box 62 at the position corresponding to the position of the dust brush 63. When odor flows into the pipe 11, the filter sheet 61 can isolate some particles and dust from flowing into the pipe 11, so as to reduce the blockage of the microporous structure in the filler and reduce the interference with the absorption of odor, and the dust brush 63 can timely remove the dust adsorbed on the filter sheet 61, so as to reduce the blockage of the air inlet end of the air duct caused by dust accumulation.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
