Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency and energy-saving horizontal flow wastewater baffle reactor. Background Technology

[0002] The working principle of a folded plate reactor is to fold a planar reaction tank into multiple layers, optimizing the ratio of surface area to internal space. This allows fluid to flow easily along the fold lines, thereby improving reaction efficiency. Specifically, the folded plate reactor utilizes the tortuous flow and continuous contraction and expansion of water within the folds to accelerate the collision of particles in the water. Under the action of flocculants, larger flocs gradually form and settle.

[0003] Existing baffle reactors mostly use vertical flow paths. Vertical flow causes the flocculants produced by the flocculants to sink to the bottom of the channel, which increases the resistance of the water flow in the channel and increases the energy consumption of the water flow. In addition, the number of contraction and expansion cycles per unit volume is not high, resulting in low mixing efficiency between the flocculants and the water. Therefore, a high-efficiency and energy-saving horizontal flow baffle reactor for sewage is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency and energy-saving horizontal flow wastewater baffle reactor.

[0005] The technical solution of this utility model is: a high-efficiency and energy-saving horizontal flow wastewater baffle reactor, including an inlet chamber, a feeder at the top of the inlet chamber, an inlet pipe fixedly connected to the left side of the inlet chamber, a treatment chamber connected below the inlet chamber, a collection trough at the upper left side of the treatment chamber, multiple vertical baffles fixedly connected inside the treatment chamber, a flow channel formed between the multiple vertical baffles, multiple horizontal baffles inside the flow channel, a horizontal flow channel formed between the multiple horizontal baffles and the vertical baffles, the multiple horizontal flow channels being sequentially connected along the water flow direction, and a drainage trough connected to the right side of the treatment chamber.

[0006] Furthermore, the feeder includes a feeding bin, which is fixedly connected to the top of the water inlet bin via a connecting rod. A vent pipe is fixedly connected to the top of the feeding bin, and an air pump is fixedly connected to the top of the water inlet bin. The air outlet of the air pump is connected to the right end of one end of the vent pipe. A feeding mechanism is rotatably connected inside the feeding bin.

[0007] Explanation: The flocculant is sprayed into the inlet chamber by the airflow of the air pump, which can evenly spray the flocculant into the inlet chamber.

[0008] Furthermore, the feeding mechanism includes a spiral connecting rod, the top of which is rotatably connected to the top of the feeding bin, the bottom of which is rotatably connected to the bottom of the vent pipe, a spiral blade is fixedly connected to the outer wall of the spiral connecting rod located in the feeding bin, and a wind turbine is fixedly connected to the outer wall of the spiral connecting rod located in the vent pipe.

[0009] Explanation: By blowing airflow to drive the impeller, the spiral connecting rod rotates, thereby achieving automatic feeding. The impeller will disperse the falling flocculant. This structure does not require a motor to drive the spiral connecting rod, which can save on the manufacturing cost of the device and reduce the energy consumption of the feeder.

[0010] Furthermore, the water inlet chamber includes a chamber body, inside which a spiral baffle is fixedly connected, and on top of the spiral baffle is a baffle plate fixedly connected.

[0011] Note: The baffle plate can change the flow velocity of the water, which can promote the mixing of water and flocculant.

[0012] Furthermore, a sedimentation tank is provided at the beginning of the horizontal flow channel along the water flow direction. The sedimentation tank is inserted from the outer wall of the treatment chamber inward, and the outer side of the sedimentation tank is fixed to the outer wall of the treatment chamber with screws. The inner end of the sedimentation tank is engaged with the vertical folding plate and the horizontal folding plate.

[0013] Explanation: After the water flows through the sedimentation tank, the flocculated sediment produced by flocculation settles into the sedimentation tank due to gravity. The sedimentation tank is used to collect the flocculated sediment in the wastewater.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a feeder to introduce flocculant into the inlet tank. The flow is agitated by baffles on a spiral baffle, promoting mixing between the flocculant and the water. The mixture of flocculant and wastewater is further agitated by vertical and horizontal baffles, creating channels of varying widths within the flow channel. The flow velocity changes as the water passes through these channels, further promoting mixing. The flow channel exhibits numerous width variations per unit volume, thus increasing the mixing efficiency between the flocculant and the water. Furthermore, the water flow is powered by the gravitational potential energy of the water, resulting in low energy consumption. Attached Figure Description

Detailed Implementation

[0021] Example 1:

[0022] like Figure 1 , Figure 2 As shown, a high-efficiency and energy-saving horizontal flow wastewater baffle reactor includes an inlet chamber 1, a feeder 2 at the top of the inlet chamber 1, an inlet pipe 3 fixedly connected to the left side of the inlet chamber 1, a treatment chamber 4 connected to the bottom of the inlet chamber 1, a collection trough 41 at the upper left side of the treatment chamber 4, multiple vertical baffles 42 fixedly connected inside the treatment chamber 4, a flow channel 43 formed between the multiple vertical baffles 42, multiple horizontal baffles 44 inside the flow channel 43, a horizontal flow channel 45 formed between the multiple horizontal baffles 44 and the vertical baffles 42, the multiple horizontal flow channels 45 being connected sequentially along the water flow direction, and a drainage channel 46 connected to the right side of the treatment chamber 4.

[0023] like Figure 3 As shown, the feeder 2 includes a feeding bin 21, which is fixedly connected to the top of the water inlet 1 via a connecting rod 22. A vent pipe 23 is fixedly connected to the top of the feeding bin 21, and an air pump 24 is fixedly connected to the top of the water inlet 1. The air outlet of the air pump 24 is connected to the right end of one end of the vent pipe 23. A feeding mechanism 25 is rotatably connected inside the feeding bin 21.

[0024] The flocculant is sprayed into the water inlet chamber 1 by the airflow of the air pump 24, which can evenly spray the flocculant into the water inlet chamber 1.

[0025] The feeding mechanism 25 includes a spiral connecting rod 251. The top of the spiral connecting rod 251 is rotatably connected to the top of the feeding bin 21, and the bottom of the spiral connecting rod 251 is rotatably connected to the bottom of the vent pipe 23. A spiral blade 252 is fixedly connected to the outer wall of the spiral connecting rod 251 located in the feeding bin 21, and a wind turbine 253 is fixedly connected to the outer wall of the spiral connecting rod 251 located in the vent pipe 23.

[0026] By blowing air through the impeller 253, the spiral connecting rod 251 is rotated, thereby achieving automatic feeding. The impeller 253 will disperse the falling flocculant. This structure does not require a motor to drive the spiral connecting rod 251, which can save the manufacturing cost of the device and reduce the energy consumption of the feeder 2.

[0027] Example 2:

[0028] The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, the water inlet chamber 1 includes a chamber body 11, a spiral baffle 12 is fixedly connected inside the chamber body 11, and a baffle plate 13 is fixedly connected to the top of the spiral baffle 12.

[0029] Compared with Example 1, in this embodiment, the baffle 13 can change the flow velocity of the water, which can promote the mixing of water and flocculant.

[0030] Example 3:

[0031] The difference between this embodiment and embodiment 2 is that a sedimentation tank 451 is provided at the beginning of the horizontal flow channel 45 along the water flow direction. The sedimentation tank 451 is inserted into the outer wall of the treatment chamber 4, and the outer side of the sedimentation tank 451 is fixed to the outer wall of the treatment chamber 4 with screws. The inner end of the sedimentation tank 451 is engaged with the vertical folding plate 42 and the horizontal folding plate 44.

[0032] The difference between this embodiment and embodiment 2 is that after the water flows through the sedimentation tank 451, the flocculated sediment produced by flocculation sinks into the sedimentation tank 451 due to gravity, and the flocculated sediment in the sewage is collected through the sedimentation tank 451.

[0033] The working method of the above embodiments includes the following steps:

[0034] S1. Wastewater is introduced into the inlet chamber 1 through the inlet pipe 3. Flocculant is added into the inlet chamber 1 through the feeder 2. The mixture of wastewater and flocculant flows through the spiral baffle 12 and is disturbed by the baffle 13, which promotes the mixing of flocculant and water before entering the treatment chamber 4.

[0035] S2. The mixture of wastewater and flocculant flows into the horizontal flow channel 45 through the collection channel 41. The varying width of the channels in the horizontal flow channel 45 creates differences in the flow velocity of the water, thereby promoting the mixing of water and flocculant. The resulting flocculent sediments are collected in the sedimentation tank.

[0036] S3. The airflow generated by the air pump 24 blows the impeller 253, which in turn causes the spiral connecting rod 251 to rotate, driving the spiral blades 252 to rotate and causing the flocculant to be discharged from the feeding bin 21.

[0037] In the above embodiments, the air pump 24 is a commercially available product. As long as it can achieve the function of this utility model, it is acceptable. Those skilled in the art can choose to use it based on common sense, and no special limitations are made here.
