Description

Technical Field

[0001] The invention relates to the technical field of biological trickling filtration, and in particular to a gas-liquid coordinated treatment biological trickling filtration device for a chicken house. Background Art

[0002] The existing chicken house contains a large amount of dust, as well as gases containing ammonia and hydrogen sulfide. The air containing chicken feed powder, ammonia and hydrogen sulfide in the chicken house is blown out by a blast structure and sent to the water storage area under the trickling filter through a connecting pipe to aerate the water layer. Then, the denitrifying bacteria treatment device is used to treat the nitrogen compounds in the water. A porous filler with denitrification and desulfurization bacteria is installed in the biological trickling filter area in the tower to degrade pollutants in the gas. A spray head is installed in the spray area on the tower to spray water from the water storage area under the tower to the biological trickling filter area in the tower to further promote gas-liquid contact and dissolution of pollutants. The exhaust hole on the top of the tower is used to discharge the treated gas. The following problems usually exist when treating dust and gases containing ammonia and hydrogen sulfide: First, during the aeration of the water layer, the gas will enter the water storage area under the tower in the form of bubbles. Therefore, these bubbles will carry some dust and reach the biological trickling filter area in the tower as the bubbles rise, so it is very easy to block the porous filler in the biological trickling filter area in the tower. Secondly, if the air flow rate increases, the time it takes for the air flow to pass through the porous filler in the biological trickling filter area in the tower will be shorter, which will undoubtedly reduce the degradation effect of denitrification and desulfurization bacteria on pollutants in the gas. Therefore, the pollutants in the gas are not fully degraded and are discharged from the device, resulting in the problem of reduced degradation efficiency.

[0003] Therefore, we designed a biotrickling filter device for gas-liquid coordinated treatment in chicken houses. Summary of the invention

[0019] Reference Figure 1-Figure 14 A gas-liquid coordinated treatment bio-trickling filter device for chicken houses comprises a fixed bracket 3, and an outer tower tank 1 and an inner tower tank 2 arranged on the fixed bracket 3, the outer tower tank 1 is coaxially sleeved on the outer side wall of the inner tower tank 2, and an inner cavity 11 is formed between the outer tower tank 1 and the inner tower tank 2, referring to Figure 2 and Figure 3 State, the setting of the inner cavity 11 effectively avoids directly pumping water from the inner cavity 11, but sets a buffer zone, namely the inner cavity 11, to ensure that the precipitated impurities in the water storage area under the tower will not be directly pumped out, but will serve as a temporary storage area for precipitation, preventing impurities in the water body from reaching the top of the porous filling disk 20 along with the flow of the water body, and then blocking the porous filling disk 20, so that the airflow cannot flow normally.

[0020] The tank 2 in the tower is equipped with a water storage area under the tower for aerating the water layer. A liquid exchange pipe 4 for replacing the water body inside the tower is opened at the bottom of the tank 2 in the tower, which is convenient for replacing the water body in the water storage area under the tower, so that the aeration progress of the water layer can run normally. At the same time, a denitrifying bacteria treatment device is provided in the water storage area under the tower, which is used to treat nitrogen compounds in the water.

[0021] An arc-shaped pipe 15 for introducing gas is provided in the water storage area under the tower. A plurality of air holes are opened on the arc-shaped pipe 15, and an exhaust valve 16 is provided in the air holes. Air containing chicken feed powder, ammonia and hydrogen sulfide is blown into the water storage area under the tower through the exhaust valve 16 in the arc-shaped pipe 15 by a blower, thereby aerating the water layer. At the same time, the setting of the exhaust valve 16 also prevents the water in the water storage area under the tower from entering the arc-shaped pipe 15.

[0022] Reference Figure 2 and Figure 3In this state, a plurality of liquid inlet holes 9 are provided on the liquid suction frame 7, and the liquid inlet holes 9 are immersed in the water storage area under the tower. Therefore, under the action of an external water pump, the water in the water storage area under the tower can be pumped into the liquid suction frame 7. A connecting hole 10 connecting the inner cavity 11 and the liquid suction frame 7 is provided on the inner tank 2 of the tower, and the water enters the inner cavity 11 along the connecting hole 10. A liquid suction pipe 19 is provided on the outer tank 1 of the tower, and the liquid suction pipe 19 is connected to the liquid spray frame 8 through a rubber hose. A liquid suction rack 7 and a liquid spray rack 8 are respectively provided at the bottom and top of the inner wall of the tank 2 in the tower. The liquid spray rack 8 is provided with a plurality of first spray ports, wherein an external water pump is arranged in the liquid suction pipe 19 to drive the water body to rise slowly, so as to prevent impurities in the water body from being lifted along with the faster water flow. Then the water body will reach the liquid spray rack 8 along the rubber hose (the rubber hose in the figure is not marked), and then this part of the water body will be sprayed out from the first spray port on the liquid spray rack 8 and sprinkled onto the porous filling disk 20, so as to further promote gas-liquid contact and the dissolution of pollutants.

[0023] The inner tank 2 of the tower is also provided with a plurality of porous filling disks 20 for degrading gaseous pollutants. The porous filling disks 20 are porous fillings for denitrification and desulfurization bacteria. The gas passing through the water storage area under the tower will reach the bottom of the porous filling disks 20, and then pass through the plurality of porous filling disks 20 from the bottom of the porous filling disks 20 and reach the top, which is used to degrade pollutants in the gas. The porous filling disk 20 is coaxially inserted with a rotating rod 12 extending into the water storage area under the tower, a rotating disk 13 is fixed to the side wall of the rotating rod 12, and a fan blade 14 is provided on the rotating disk 13 for driving the rotating rod 12 to rotate, and the rotating fan blade 14 is fixed to the outer wall of the rotating disk 13, so the airflow flowing from bottom to top will drive the fan blade 14 on the rotating disk 13 to rotate. Since the rotating rod 12 includes a fixed rod 121 and a rotating rod 122, the rotating rod 122 rotates coaxially at the bottom of the fixed rod 121, and a lifting chamber is provided in the rotating rod 12, and the lifting chambers are both opened at the opposite ends of the rotating rod 122 and the fixed rod 121. This arrangement can ensure that the rotation of the rotating rod 122 will not drive the rotation of the fixed rod 121, and the fixed rod 121 is connected to the porous filling disk 20, and the outer wall of the rotating rod 122 is fixed to the rotating disk 13, so the rotation of the fan blade 14 will also drive the rotating rod 122 to rotate, and the greater the airflow speed, the faster the rotation speed of the rotating rod 122.

[0024] Reference Fig.14State, a spiral body 41 extending into the lifting chamber is arranged below the fixed disk 37, and the spiral body 41 rotates upward. The rotating disk 13 is connected with the lifting chamber through a connecting pipe 42, and a plurality of second spraying ports are opened on the rotating disk 13. The spiral body 41 is fixed to the inner wall of the rotating rod 122. Therefore, when the rotating rod 122 rotates, the water body in the water storage area under the tower will be lifted. Since the connecting pipe 42 is arranged at the bottom of the fixed disk 37, the water body will enter the rotating disk 13 along the connecting pipe 42, and be sprayed out along the second spraying port, and the gas-liquid will contact and the pollutants will be dissolved again, so as to realize the secondary treatment of the gas. The setting of the liquid spraying frame 8 is for the tertiary treatment of the gas. Therefore, the device can realize the tertiary treatment of the supplied gas.

[0025] Reference Fig.14 In this state, a lifting chamber is coaxially provided with a lifting rod 23, and a pressing plate 30 is fixed at the bottom of the lifting rod 23, and a fixed plate 37 is fixed to the inner wall of the lifting chamber below the pressing plate 30. The pressing plate 30 and the fixed plate 37 are connected by a tension spring 38. Therefore, the pressing plate 30 has a tendency to be pressed downward under the action of the tension spring 38. However, since there are multiple telescopic components sliding on the inner wall of the lifting chamber between the pressing plate 30 and the fixed plate 37, the telescopic components include multiple telescopic plates 36 arranged in a circle, which will limit the descent of the pressing plate 30.

[0026] Since a counterweight is provided on the telescopic plates 36 , when the rotating rod 122 rotates, the plurality of telescopic plates 36 will perform centrifugal motion in the transverse cavity 35 , that is, slide in the transverse cavity 35 .

[0027] Since the telescopic plate 36 telescopes and slides on the inner wall of the lifting chamber through the transverse chamber 35, the telescopic assembly slides in the transverse chamber 35 from top to bottom through the first compression spring 31, the second compression spring 32, the third compression spring 33 and the fourth compression spring 34 in sequence, and the elastic coefficients of the first compression spring 31, the second compression spring 32, the third compression spring 33 and the fourth compression spring 34 increase in sequence. This arrangement ensures that as the rotation speed of the rotating rod 122 increases, the centrifugal force on the telescopic plate 36 becomes greater, and the corresponding force of squeezing the first compression spring 31, the second compression spring 32, the third compression spring 33 and the fourth compression spring 34 becomes greater, and the telescopic plate 36 will first squeeze the first compression spring 31 to retract into the transverse chamber 35, and release the limit on the pressing plate 30, so the pressing plate 30 will pass over the telescopic plate 36 connected to the first compression spring 31, and press against the upper surface of the telescopic plate 36 connected to the second compression spring 32; As the wind speed increases and the rotation speed of the rotating rod 122 increases, the centrifugal force on the telescopic plate 36 will increase. The telescopic plate 36 connected to the first compression spring 31, the second compression spring 32, the third compression spring 33 and the fourth compression spring 34 will be retracted into the transverse cavity 35 in sequence, so that the pressing plate 30 will be lowered in a step-by-step manner with the lifting rod 23, which is convenient for the subsequent adjustment of the porous filling plate 20.

[0028] The telescopic plate 36 is provided with a chamfer on the side facing the fixed plate 37, and a toggle plate 39 is fixed on the outer wall of the lifting rod 23, and the toggle plate 39 is lifted on the rotating rod 12 through the side sliding hole 40. It should be noted that the biological trickling filter area is located in the tank 2 in the tower. This arrangement is to solve the problem of sudden excessive airflow, which leads to a shorter time for the airflow to pass through the porous filler in the biological trickling filter area in the tower, which will undoubtedly reduce the efficiency of denitrification and desulfurization bacteria in degrading pollutants in the gas, that is, to ensure that the device encounters an emergency situation of sudden increase in airflow during use, thereby adding protective measures to ensure that the porous filling plate 20 can still process the gas passing through, and the problem of reduced efficiency of denitrification and desulfurization bacteria in degrading pollutants in the gas will not occur.

[0029] Reference Figure 4-Figure 9 In this state, a tray rack 18 is fixed to the inner wall of the tank 2 in the tower, and a plurality of porous filling trays 20 are stacked and placed on the tray rack 18, and a spiral block 24 is provided in the lifting chamber, and the lifting rod 23 is lifted and slid through the lifting plate 22, and the spiral block 24 is fixed to the outer wall of the lifting rod 23, and the pressing plate 30 is stepped down with the lifting rod 23, and the spiral block 24 is also stepped down with it. At the same time, since the toggle plate 39 is lifted on the rotating rod 12 through the side sliding hole 40, when the pressing plate 30 is lowered, the toggle plate 39 will be lifted by the external pushing electric push rod, so that the pressing plate 30 drives the lifting to the top telescopic plate 36 and resets. At this time, the external pushing electric push rod is powered off, and the external pushing electric push rod will not affect the descent of the pressing plate 30 during the descent of the pressing plate 30, wherein the external pushing electric push rod is a prior art and will not be elaborated on here.

[0030] The porous filling disk 20 is provided with a protruding block 26 extending into the lifting chamber, and the spiral block 24 is against the protruding block 26, the protruding block 26 extends into the lifting chamber through the side hole 25, and the side wall of the protruding block 26 is provided with an arc frame 27 sliding on the inner wall of the lifting chamber, the arc frame 27 is provided with an arc groove 28 on the side of the side wall of the lifting chamber, and a fixing plate 29 extending into the arc groove 28 is fixed to the inner wall of the lifting chamber, a return spring is provided in the arc groove 28, and one end of the return spring is against the fixed plate 29, during the resetting process of the spiral block 24, the porous filling disk 20 will return to its initial position under the action of the return spring, wherein during the step-by-step descent of the spiral block 24, it will continuously touch the protruding block 26 extending into the lifting chamber on the porous filling disk 20 and push the porous filling disk 20 to rotate.

[0031] A plurality of vertical holes 17 are circumferentially formed on the porous filling disk 20 , and a plurality of inclined holes 21 are spirally formed on the porous filling disk 20 . The inclined holes 21 are connected to the tops of the vertical holes 17 .

[0032] Reference Figure 10-13 State, that is, a schematic diagram of the state in which multiple porous filling disks 20 rotate.

[0033] The initial state is Fig.10 At this time, a plurality of porous filling trays 20 are stacked on the tray rack 18, and the bottom porous filling tray 20 is fixed on the tray rack 18. At the same time, an air inlet hole is opened at the bottom of the tray rack 18, and the air inlet hole is connected to the inclined hole 21 of the bottom porous filling tray 20. Fig.10 The airflow is as shown in the figure; When the spiral block 24 starts to descend in a step-by-step manner, and continuously touches and pushes against the multiple porous filling disks 20, rotating from top to bottom, a Figure 11-13 The three states are states in which the airflow increases successively. As can be seen from the figure, the route of the airflow passing through multiple porous filling disks 20 becomes longer, which can effectively avoid the problem of faster airflow velocity. Then the time for the airflow to pass through the porous filler in the biological trickling filter area in the tower is shorter, that is, the problem of reduced efficiency in treating pollutants in the gas is avoided. The problem of reduced degradation efficiency caused by increased airflow velocity is addressed by increasing the length of the airflow channel.

[0034] The top cover of the tank 2 in the tower is provided with a tower tank cover 5, and a tower top exhaust pipe 6 is installed on the tower tank cover 5, so that the filtered gas will be discharged from the tower top exhaust pipe 6, completing the air purification and filtration of the chicken house.

[0035] The working principle of the present invention is as follows: The inner tank 2 of the tower is equipped with a water storage area under the tower for aerating the water layer. A liquid exchange pipe 4 for replacing the water body inside the tower is opened at the bottom of the inner tank 2, so that the water body in the water storage area under the tower can be replaced, so that the progress of aeration of the water layer can be run normally. At the same time, a denitrifying bacteria treatment device is provided in the water storage area under the tower. The device is used to treat nitrogen compounds in the water. Air containing chicken feed powder, ammonia and hydrogen sulfide is blown into the water storage area under the tower from the exhaust valve 16 in the arc tube 15 through a blower, thereby aerating the water layer. Then an external water pump is arranged in the liquid extraction pipe 19, and the water will reach the liquid spraying frame 8 along the rubber hose, and this part of the water will be sprayed out from the first spraying port on the liquid spraying frame 8, and sprinkled on the porous filling disk 20, further promoting the gas-liquid contact and the dissolution of pollutants. When the rotating rod 122 rotates, it will drive the water in the water storage area under the tower to rise. Since the connecting pipe 42 is arranged at the bottom of the fixed disk 37, the water will enter the rotating disk 13 along the connecting pipe 42 and be sprayed out through the second spraying port, which will once again promote the gas-liquid contact and the dissolution of pollutants, and realize the secondary treatment of the gas. The setting of the liquid spraying frame 8 is for the tertiary treatment of the gas, so the device can realize the tertiary treatment of the input gas.

[0036] Finally, the spiral block 24 begins to descend in a step-by-step manner, and continuously touches and pushes against the multiple porous filling disks 20, which rotate in sequence from top to bottom, forming a Figure 11-13 The three states are states in which the airflow increases successively. As can be seen from the figure, the route of the airflow passing through multiple porous filling disks 20 becomes longer, which can effectively avoid the problem of faster airflow velocity. Then the time for the airflow to pass through the porous filler in the biological trickling filter area in the tower is shorter, that is, the problem of reduced efficiency in treating pollutants in the gas is avoided. The problem of reduced degradation efficiency caused by increased airflow velocity is addressed by increasing the length of the airflow channel.

[0037] The filtered gas will be discharged from the exhaust pipe 6 at the top of the tower, completing the air purification and filtration of the chicken house.
