Description

Technical Field

[0001] The present invention relates to the technical field of deodorization, and particularly to a biological deodorization device for sewage treatment. Background Art

[0002] Sewage treatment plants are widely used in the treatment of industrial wastewater and domestic sewage. A large amount of intermediate gases are generated in the biological reaction and sludge treatment units, including methane, hydrogen sulfide, and some volatile organic pollutants, which seriously threaten the health and safety of human life. Therefore, it is crucial to stably and efficiently remove the harmful gases generated by sewage treatment plants. The existing deodorization processes for sewage treatment plants include technical means such as activated carbon adsorption, cooling, and washing absorption. Although the generation of harmful gases is curbed to a certain extent, the cost is high and secondary pollution is easily generated.

[0003] The microbial method has the characteristics of good decontamination effect and low cost, and is widely used in the process of pollutant degradation. Applying it to the removal of harmful gases has broad application prospects. The prior art (patent number: 201810943886.1) discloses a biological deodorization filler and device, which has greatly promoted the progress of this type of technology. This technology includes a placement block. An annular chamber is provided inside the placement block. An opening is provided on one inner wall of the annular chamber. A metal filter screen is fixedly installed in the opening. A filtering mechanism is provided in the annular chamber. A air supply mechanism is provided in the placement block. The air supply mechanism is arranged close to the center of the placement block. The air supply mechanism is communicated with the annular chamber. The upper end of the placement block is fixedly connected with an air outlet mechanism. The air outlet mechanism is communicated with the air supply mechanism. Although the above patent realizes the biological deodorization function, the microorganisms lack a suitable growth environment, which easily causes the microorganisms to lose the purification effect due to the lack of water and nutrient supply, with a short action time, high cost, and poor effect. Therefore, activating the activity of deodorizing microorganisms and prolonging their action time are the bottlenecks faced by this type of technology at present.

[0004] Combined with the actual needs, the present invention develops a biological deodorization device for sewage treatment. A water storage and spraying mechanism is provided in the device, which provides a suitable growth environment for the growth and reproduction of deodorizing microorganisms, greatly activates the activity effect of deodorizing microorganisms and prolongs their action time. The present invention is of great significance for curbing the emission of harmful gases from sewage treatment plants. Summary of the Invention

[0031] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0032] Embodiment:

[0033] As Figure 1-2 shown, a biological deodorization device for sewage treatment includes: a water storage mechanism 1, a spraying mechanism 2, a biological deodorization mechanism 3, and a control device; the biological deodorization mechanism 3 is fixedly installed at the upper end of the water storage mechanism 1 through a mounting frame 102; the water in the water storage mechanism 1 is sprayed into the biological deodorization mechanism 3 through the spraying mechanism 2; the control device controls the operation of the entire biological deodorization device for sewage treatment except itself.

[0034] Specifically, the water storage mechanism 1 is provided with a water storage tank 101 and a water pipe 106; the water storage tank 101 is fixedly installed on the mounting frame 102; the water storage tank 101 is provided with a water flow controller mounting bracket 108; the water storage tank 101 is provided with a water inlet 103 and a drain outlet 104, and the water inlet and drain in the water storage tank 101 are controlled by a water flow control device 11 fixedly installed on the water flow controller mounting bracket 108; a return port 105 is provided at the upper end of the water storage tank 101, and a water pump 107 is fixedly installed inside. One end of the water pipe 106 is fixedly connected to the outlet of the water pump 107, and the other end of the water pipe 106 is rotatably connected to the spraying mechanism 2.

[0035] Specifically, the water flow control device 11 is provided with a sliding gear set 1107, a first transmission wheel set 1105, and a trapezoidal slider 1103; the sliding gear set 1107 slides up and down and is rotatably installed on the water flow controller mounting bracket 108, and is driven by a second motor 1108 fixedly installed on the water flow controller mounting bracket 108; one end of the trapezoidal slider 1103 is rotatably installed on the sliding gear set 1107, and the other end slides up and down on the vertical plate of the water flow controller mounting bracket 108 and is driven by a first motor 1101 fixedly installed on the water flow controller mounting bracket 108; two first transmission wheel sets 1105 are symmetrically rotatably installed on the water flow controller mounting bracket 108, and one end of each is intermittently rotatably connected to the sliding gear set 1107, and the other end of each is rotatably connected to an outlet valve and an inlet valve respectively.

[0036] As a specific implementation manner of this embodiment, as Figure 4 and 7As shown in FIG. -9, the sliding gear set 1107 is fixedly connected to the output end of the second motor 1108; the output end of the first motor 1101 is fixedly connected with a centrifugal wheel 1102, and a centrifugal small cylinder is provided on the centrifugal wheel 1102. The centrifugal small cylinder is slidably installed on one end of the trapezoidal slider 1103 away from the sliding gear set 1107; both of the first transmission wheel sets 1105 are provided with gears, and the gears are intermittently engaged with the sliding gear set 1107. The other ends of both of the first transmission wheel sets 1105 are provided with transmission wheels, and the transmission wheels are respectively connected to the water outlet valve and the water inlet valve through belts 1106 for transmission.

[0037] Specifically, a braking strip 1104 is further provided on the water flow control device 11; the two braking strips 1104 are respectively slidably installed on the water flow controller mounting bracket 108 corresponding to the two first transmission wheel sets 1105, and one end is intermittently connected to the first transmission wheel set 1105 in a matching manner, and the other end is intermittently connected to the trapezoidal slider 1103 in a matching manner; as a specific implementation manner of this embodiment, a rotating shaft is provided on the first transmission wheel set 1105, and one end of the braking strip 1104 is intermittently connected to the rotating shaft on the first transmission wheel set 1105. Both of the two braking strips 1104 are elastically connected to the water flow controller mounting bracket 108 through tension springs 1109 for braking the first transmission wheel set 1105 under the reset action of the tension spring (1109).

[0038] The water in the water storage tank 101 enters the water pipe through the water pump 107, and the water falls into the deodorization tank 313 through the spraying mechanism 2; the used water then flows back from the deodorization tank 313 to the water storage tank 101, realizing the reuse of water.

[0039] When the water in the water storage tank 101 is used too many times, the first motor 1101 works. The first motor 1101 drives the centrifugal wheel 1102 to rotate, and the centrifugal wheel 1102 drives the trapezoidal slider 1103 to move downward. The lower inclined surface of the trapezoidal slider 1103 presses the lower braking strip 1104, so that the braking strip 1104 is disengaged from the rotating shaft on the first transmission wheel set 1105. The trapezoidal slider 1103 simultaneously drives the sliding gear set 1107 to move downward. When it moves to the lower end of the sliding gear set 1107 and meshes with the gear on the lower first transmission wheel set 1105, the first motor 1101 stops working; then the second motor 1108 starts to work. The second motor 1108 drives the sliding gear set 1107 to rotate, and the sliding gear set 1107 drives the lower first transmission wheel set 1105 to rotate. The first transmission wheel set 1105 drives the water outlet valve to rotate through the belt 1106 to open the water outlet valve, discharge the water in the water storage tank 101, and then the second motor 1108 works to close the water outlet valve;

[0040] When the water storage tank 101 needs to be filled with water, the first motor 1101 operates. The first motor 1101 drives the centrifugal wheel 1102 to rotate, thereby causing the centrifugal wheel 1102 to drive the trapezoidal slider 1103 to move upward. The upper inclined surface of the trapezoidal slider 1103 presses against the upper braking strip 1104, so that the braking strip 1104 is disengaged from the rotating shaft on the first transmission wheel set 1105. At the same time, the trapezoidal slider 1103 drives the sliding gear set 1107 to move upward. When the upper end of the sliding gear set 1107 meshes with the gear on the upper first transmission wheel set 1105, the first motor 1101 stops operating. When the upper gear in the sliding gear set meshes with the upper transmission gear set, the first motor stops working. Then the second motor 1108 starts to operate. The second motor 1108 drives the sliding gear set 1107 to rotate, the sliding gear set 1107 drives the upper first transmission wheel set 1105 to rotate, and the first transmission wheel set 1105 drives the water inlet valve to rotate through the belt 1106, opening the water inlet valve to allow clean water to enter the water storage tank. Then the second motor 1108 operates to close the water inlet valve;

[0041] When there is no need for water inlet and outlet, the sliding gear set 1107 is in the middle position. Under the action of the tension spring 1109, the braking strip 1104 contacts the rotating shaft on the first transmission wheel set 1105, thereby preventing the water inlet valve and the water outlet valve from rotating.

[0042] Specifically, a water guide plate 201 and a connecting block 204 are provided on the spraying mechanism 2; a deodorizing box 313 is provided on the biological deodorizing mechanism 3. The water guide plate 201 is rotatably installed at the upper end inside the deodorizing box 313 and is driven by a third motor 203 fixedly installed on the deodorizing box 313; one end of the connecting block 204 is fixedly connected to the water guide plate 201, and the other end is rotatably connected to a spray head 205; the water inlet at the upper end of the water guide plate 201 is rotatably connected to the water pipe 106, and the water outlet at the lower end extends into the water inlet of the spray head 205.

[0043] Specifically, a water wheel is further provided on the spraying mechanism 2. The water wheel is fixedly installed on the spray head 205 to disperse the water flow flowing in from the water guide plate 201.

[0044] As a specific implementation manner of this embodiment, as Figure 10-11 shown, the lower end of the connecting block 204 is inclined. The spray head 205 is rotatably installed on the inclined part at the lower end of the connecting block 204. The inclined placement of the spray head 205 can make the water flow spray more evenly in the deodorizing box 313. A plurality of round holes are opened on the side and bottom of the spray head 205, which can enable the water flow dispersed by the water wheel to flow out in all directions, making the water flow spray more evenly.

[0045] As a specific implementation manner of this embodiment, as Figure 10-12As shown, a large gear and a small gear are provided on the gear set 202. The large gear is fixedly installed on the water guide plate 201, the small gear is rotatably installed on the water guide plate 201, and the large gear and the small gear mesh with each other; the small gear is fixedly connected to the output end of the motor three 203.

[0046] The spraying mechanism 2 allows water to flow into the water guide plate 201 through the water pump 107 on the water storage tank 101. The water in the water guide plate 201 then enters the nozzle 205. A water wheel (not shown in the figure) is fixedly installed inside the nozzle 205. The impact of the water causes the water wheel to rotate, thereby driving the nozzle 205 to rotate within the connecting block 204. The motor three 203 drives the gear set 202 to rotate, the gear set 202 drives the water guide plate 201 to rotate, the water guide plate 201 drives the connecting block 204 to rotate, and the connecting block 204 drives the nozzle 205 to rotate around the center of the water guide plate 201. Through the rotation of the nozzle 205 around its own axis and around the center of the water guide plate 201, the water is fully sprayed inside the deodorization box 33, not only absorbing the soluble part, impurity particles and floating substances in the odor, but also providing a survival environment for the microorganisms on the biological deodorization mechanism 3.

[0047] Specifically, a shifting plate 309 and a driving device are also provided on the biological deodorization mechanism 3; the shifting plate 309 is rotatably installed at the bottom of the deodorization box 313, and the bottom of the shifting plate 309 passes through the deodorization box 313 and is cooperatively connected with the reflux port 105; the first deodorization plate group 301 and the second deodorization plate group 310 are symmetrically and rotatably installed on the shifting plate 309 and are driven by a driving device fixedly installed on the shifting plate 309; both the first deodorization plate group 301 and the second deodorization plate group 310 are composed of two deodorization plates, and the two deodorization plates are correspondingly rotatably installed on the shifting plate 309; air inlets and air outlets are provided on the deodorization box 313 corresponding to the first deodorization plate group 301 and the second deodorization plate group 310, and the air inlets are fixedly connected to the outlets of the suction fans fixedly installed on the mounting frame 102.

[0048] Specifically, a transmission gear set 304 and a driving gear set 307 are provided on the driving device; a first bracket 305 and a second bracket 308 are provided on the shifting disk 309; the transmission gear set 304 is rotatably installed on the first bracket 305, and a first rack 302 and a second rack 303 are slidably installed on the first bracket 305 in a staggered and parallel manner, and one ends of the first rack 302 and the second rack 303 are respectively rotatably and slidably connected to one deodorizing plate in the first deodorizing plate group 301 and the second deodorizing plate group 310, and the other ends are cooperatively connected to the transmission gear set 304; the driving gear set 307 is rotatably installed on the second bracket 308 and is driven by a fifth motor 314 fixedly installed on the second bracket 308; a first rack 302 and a second rack 303 are slidably installed on the second bracket 308 in a staggered and parallel manner, and one ends of the first rack 302 and the second rack 303 are respectively rotatably and slidably connected to the other deodorizing plate in the first deodorizing plate group 301 and the second deodorizing plate group 310, and the other ends are cooperatively connected to the driving gear set 307; the driving gear set 307 is in transmission connection with the transmission gear set 304 through a belt.

[0049] Specifically, a fourth motor 311 and a second gear set 312 are further provided on the biological deodorization mechanism 3; the second gear set 312 is fixedly connected to the displacement disk 309 and is driven by the fourth motor 311 fixedly installed on the deodorization box 313.

[0050] As a specific implementation manner of this embodiment, as Figure 13-16 shown, a plurality of round rods 306 are symmetrically and fixedly installed on the shifting disk 309, and the deodorizing plates on the first deodorizing plate group 301 and the second deodorizing plate group 310 are rotatably installed on the shifting disk 309 through the round rods 306; a gear is provided at the upper end of the transmission gear set 304, and the gear meshes with the first rack 302 and the second rack 303; a gear is provided at the upper end of the driving gear set 307, and the gear meshes with the first rack 302 and the second rack 303; two meshing gears are provided at the lower end of the driving gear set 307, the left gear at the lower end is fixedly connected to the output end of the fifth motor 314, and a transmission wheel is synchronously rotatably connected to the right gear; a transmission wheel is provided at the lower end of the transmission gear set 304, and the transmission wheel provided at the lower end of the driving gear set 307 is in belt transmission connection with the transmission wheel; a large gear and a small gear are provided on the second gear set 312, the large gear is fixedly connected to the shifting disk 309, the small gear is fixedly connected to the output end of the fourth motor 311, and the large gear and the small gear mesh with each other.

[0051] As a specific implementation manner of this embodiment, the first deodorizing plate group 301 and the second deodorizing plate group 310 are made of water-permeable and air-permeable materials, and there is a deodorizing biological filler layer inside the deodorizing plates; the deodorizing biological filler layer is a combined filler of volcanic rock, bamboo charcoal and bark, which can provide organic matter as a nutrient source for microorganisms by itself; the microorganisms on the filler layer form a microbial film in the filler layer, and degrade the malodorous substances through the metabolic activities of the microorganisms; the spraying mechanism removes part of the aerosol and dust by spraying water, increases the humidity of the odor gas, and provides the water required by the microorganisms to meet the growth needs of the microorganisms.

[0052] Under the action of the induced draft fan, the odor gas enters the biological deodorization mechanism 3 from the air inlet, passes through the first deodorizing plate group 301 and the second deodorizing plate group 310 for deodorization, and then exits from the induced draft fan.

[0053] The motor five 314 drives the driving gear group 307, the driving gear group 307 drives the rack one 302 and the rack two 303 to slide towards each other. At the same time, the driving gear group 307 drives the transmission gear group 304 to rotate, and then drives the rack one 302 and the rack two 303 meshing with the transmission gear group 304 to slide towards each other. In this embodiment, chutes are provided on both the first deodorizing plate group 301 and the second deodorizing plate group 310, and sliders are slidably installed on the chutes. One end of the rack one 302 and the rack two 303 is rotatably connected to the slider. One end of the rack one 302 and the rack two 303 pulls the slider, so that the slider moves in the chutes of the first deodorizing plate group 301 and the second deodorizing plate group 310, and the slider drives the first deodorizing plate group 301 and the second deodorizing plate group 310 to rotate inwards around the round rod 306 on the displacement disk 309, so that the first deodorizing plate group 301 forms a "<" shape and the second deodorizing plate group 310 forms a ">" shape.

[0054] Then, the motor four 311 fixed outside the lower end of the deodorizing box 313 drives the gear group two 312 to rotate, so as to drive the displacement disk 309 to rotate, and interchange the positions of the first deodorizing plate group 301 and the second biological deodorizing plate 310 group. After the position is interchanged, the motor five inside the deodorizing box 313 is started, so that the first deodorizing plate group 301 and the second deodorizing plate group 310 are restored to the open shape.

[0055] Since the first deodorizing plate group 301 comes into contact with the odor gas first compared with the second deodorizing plate group 310, and the odor gas treated by the second deodorizing plate group 310 is filtered by the first deodorizing plate group 301, the utilization rate of the first deodorizing plate group 301 is higher than that of the second deodorizing plate group 310, and more pollutants accumulate in the odor plates. When too many pollutants accumulate, the microorganisms on the first deodorizing plate group 301 cannot degrade all the pollutants in time. Therefore, after using for a period of time, the ventilation can be closed, and then the first deodorizing plate group 301 and the second deodorizing plate group 310 can be interchanged and then ventilated, so that the pollutants on the second deodorizing plate group 310 increase, and the biological deodorizing plates are fully utilized.

[0056] The control device controls the operation of the entire biological deodorization device for sewage treatment except itself.

[0057] Working principle:

[0058] First step, start motor 1101 and motor 1108 to send clean water into water storage tank 101.

[0059] Second step, start water pump 107 to send water into spraying mechanism 2, and then start the suction fan.

[0060] Third step, start motor 203 to evenly spray the water in spraying mechanism 2 into deodorization tank 313.

[0061] Fourth step, after filtering for a period of time, start motor 311 to interchange the positions of the first deodorization plate group 301 and the second biological deodorization plate group 310.
