Description

Technical Field

[0001] The invention belongs to the field of wastewater treatment, and in particular relates to acidic wastewater treatment equipment based on disinfectant production. Background Art

[0002] The acidic wastewater (pH < 6) generated during the disinfectant production process is a high-concentration, difficult-to-degrade industrial wastewater. It usually contains high-concentration inorganic acids (such as hydrochloric acid and sulfuric acid), organic acids, residual disinfectants (such as hypochlorous acid and peracetic acid) and by-products (such as halogenated organic matter). It is highly corrosive, high in salt content and biologically toxic, and requires targeted treatment.

[0003] Currently, acidic wastewater treatment primarily involves a multi-step, process-based approach using various devices, including neutralization, sedimentation, and filtration. When neutralizing wastewater, limestone powder (CaCO3) is typically used to neutralize acidic ions.

[0004] The existing neutralization process is to first pass acidic wastewater into the box, then add limestone powder into the box, and then stir to mix the wastewater and limestone powder evenly, so that CaCO3 reacts with acidic ions to form CaSO4, which will settle to the bottom of the box, thereby removing the acidic ions in the wastewater.

[0005] Since limestone powder is easy to aggregate and clump, after adding limestone powder to wastewater at one time or continuously, the agglomerated limestone powder will be suspended in the wastewater. The limestone powder on the outside will react with the acidic ions first. Since the limestone powder and the acidic ions react to generate CaSO4 precipitate, the unreacted CaCO3 inside the agglomerate will be wrapped by the generated CaSO4 and then precipitate, resulting in increased limestone powder consumption and waste of limestone powder. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention blows the neutralizer from bottom to top into the premixing chamber through a blowing pipe, and at the same time sprays the wastewater from top to bottom into the premixing chamber through a feeding mechanism, so that the wastewater and the neutralizer are fully in contact. At the same time, the neutralizer and the wastewater collide, which can break up the agglomerated neutralizer. Under the impact of the subsequent water flow, the generated CaSO4 will fall quickly, and the subsequent neutralizer will not be wrapped by the CaSO4, thereby avoiding the waste of the neutralizer. At the same time, the present invention fully mixes the wastewater and the neutralizer in the premixing stage. Compared with the prior art in which the two materials are added successively and the neutralizer is slowly infiltrated into the wastewater, the present invention has higher reaction efficiency and better neutralization effect.

[0019] 2. The present invention provides a rotating tube and a spreading hood, and a gas gathering hood is provided inside the spreading hood. The rotating spreading hood can form a water curtain of wastewater under the action of centrifugal force, and a gap is left between the spreading hood and the gas gathering hood, through which wastewater is discharged. This can reduce the amount of water discharged while making the water curtain formed by the wastewater thinner. After meeting the neutralizer, the mixing ratio of the wastewater and the neutralizer can be made more appropriate, thereby improving the neutralization effect and avoiding wasting the neutralizer. At the same time, the gas discharged from the blowing pipe and the gas generated by the reaction enter the exhaust pipe from the gas gathering hood and are discharged, thereby avoiding the gas destroying the water curtain and subsequently reducing the mixing effect of the neutralizer and wastewater.

[0020] 3. The present invention provides an air chute assembly and introduces air into the lower feed pipe through a second blower, thereby filling the gaps between the material particles with air and forming a fluidized state. The fluidized neutralizer naturally flows downward in the inclined lower feed pipe. After flowing into the blowing pipe, the neutralizer is blown out from the top by the larger airflow in the blowing pipe, thereby avoiding the situation where the amount of material fed per unit time is small due to the poor fluidity of the limestone powder.

[0021] 4. The present invention provides a spraying mechanism. When the airflow blows out of the spray funnel, the airflow drives the spray funnel to rotate. Under the action of centrifugal force, the neutralizer is scattered over a larger area and dispersed more widely, thereby reducing the agglomeration of the neutralizer. At the same time, after the airflow blows onto the blocking ball, the airflow flows along the surface of the blocking ball and is eventually discharged from the gas collecting hood and exhaust pipe above the blocking ball. Under the action of centrifugal force, the neutralizer is thrown onto the side wall of the premixing chamber by the spray funnel, thereby preventing the airflow from affecting the mixing of wastewater and neutralizer. After the first blower stops working, the blocking ball will fall onto the spray funnel, blocking the blowing pipe, thereby preventing the residual wastewater in the feeding pipe from falling into the blowing pipe and then damaging the first blower.

[0022] 5. The present invention provides a backflow prevention mechanism. When ventilation is conducted in the blowpipe, the airflow lifts the block and the sliding cylinder, causing a gap to appear between the block and the spherical head. The airflow flows out from the gap. After the first blower stops working, the sliding cylinder falls under the action of gravity, and the conical surface becomes tangent to the spherical head again, preventing the neutralizer from falling under the wind collecting hood, thereby protecting the first blower.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0033] like Figure 1-Figure 7 As shown, an acidic wastewater treatment device based on disinfectant production provided by the present invention includes a neutralization box 1, a spherical premixing chamber 10 and a reaction chamber 14 connected to the premixing chamber 10 are provided inside the neutralization box 1, and the reaction chamber 14 is located below the premixing chamber 10. A discharge pipe 15 connected to the reaction chamber 14 is installed on the side of the neutralization box 1, and a feeding mechanism 2 is installed on the top of the neutralization box 1. One end of the feeding mechanism 2 extends to the inner top of the premixing chamber 10, and the feeding mechanism 2 is used to spray wastewater into the premixing chamber 10;

[0034] The interior of the premixing chamber 10 is fixedly connected to a blowing pipe 4 through a first fixing frame 11. One end of the blowing pipe 4 extending out of the neutralization box 1 is fixedly connected to a first blower 3. The first blower 3 is fixedly installed on the neutralization box 1. A storage chamber 12 is also provided inside the neutralization box 1. The bottom of the storage chamber 12 is connected to a discharge pipe 13. One end of the discharge pipe 13 is connected to the blowing pipe 4. The discharge pipe 13 is arranged obliquely downward. A feeding port 5 connected to the storage chamber 12 is provided on the neutralization box 1. The storage chamber 12 contains a neutralizer (limestone powder).

[0035] Specifically, the neutralizer (limestone powder) is added to the storage chamber 12 through the feeding port 5, and the first blower 3 is started first. The first blower 3 extracts air and sends it into the premixing chamber 10 through the blowing pipe 4. Under negative pressure, the neutralizer in the storage chamber 12 is drawn into the blowing pipe 4, and driven by the air flow, the neutralizer is sprayed into the premixing chamber 10. After the neutralizer is sprayed into the premixing chamber 10, wastewater is sprayed into the premixing chamber 10 from the feeding mechanism 2 to form a water curtain. The wastewater will flow down the side wall of the premixing chamber 10, and the neutralizer will be evenly sprayed on the side wall of the premixing chamber 10. The wastewater and the neutralizer will come into contact with each other. , and then the neutralizer is dissolved in the wastewater, and then flows into the reaction chamber 14 together for full reaction, so that the wastewater and the neutralizer are fully mixed, and the neutralizer collides with the water curtain, which can break up the agglomerated neutralizer, and under the impact of the subsequent water flow, the generated CaSO4 will quickly fall into the reaction chamber 14, and the subsequent neutralizer will not be wrapped by CaSO4, avoiding the waste of the neutralizer. At the same time, compared with the prior art in which the two materials are added successively and the neutralizer is slowly infiltrated into the wastewater, the present invention fully mixes the wastewater and the neutralizer in the premixing stage, so that the reaction efficiency is higher and the neutralization effect is better.

[0036] Since the wastewater and the neutralizer are evenly mixed in the premixing stage, if the subsequent structure is reasonably designed, the device can be used to continuously treat the wastewater, and the subsequent wastewater transportation stage can be used for full reaction without affecting the subsequent treatment process.

[0037] The present invention provides an acidic wastewater treatment equipment based on disinfectant production. In this embodiment, the feeding mechanism 2 includes a feeding pipe 21 fixedly mounted on the neutralization box 1, one end of the feeding pipe 21 is connected to a rotary joint 23, one end of the rotary joint 23 is connected to a rotating tube 24, the rotating tube 24 is rotatably mounted on the neutralization box 1, and one end of the rotating tube 24 extending into the premixing chamber 10 is connected to a spreading cover 26, and a plurality of evenly distributed first material guide oblique strips 29 are fixedly connected to the inner side wall of the spreading cover 26, and the first material guide oblique strips 29 are inclined relative to the vertical plane;

[0038] The feeding mechanism 2 further includes a driving mechanism, which is used to drive the rotating tube 24 to rotate.

[0039] Specifically, the wastewater flows into the rotating tube 24 from the feeding pipe 21 and is sprayed out from the spreading cover 26. At the same time, the driving mechanism drives the rotating tube 24 and the spreading cover 26 to rotate, and the outer wastewater flows out along the inclined water channel between the first guide strips 29 and is thrown onto the side wall of the premixing chamber 10 by centrifugal force, thereby dispersing the wastewater. At the same time, due to the cohesive force between the liquid molecules, the wastewater on the outside will pull the wastewater in the center to move outward, so that the wastewater is sprayed out in the form of a water curtain, and then the neutralizer sprayed from the blowing pipe 4 meets the wastewater and merges.

[0040] The present invention provides an acidic wastewater treatment equipment based on disinfectant production. Since the reaction between limestone powder and ions in the wastewater will generate gas, and the gas ejected from the blowing pipe 4 also needs to be discharged, in order not to affect the formation of the water curtain, in this embodiment, the feeding mechanism 2 also includes an exhaust pipe 22, and the exhaust pipe 22 is fixedly installed inside the feeding pipe 21. The top end of the exhaust pipe 22 extends out of the feeding pipe 21, and the bottom end of the exhaust pipe 22 extends to the inside of the sprinkling hood 26 and is fixedly connected to the gas gathering hood 28. The gas gathering hood 28 is provided with a plurality of air inlets connected to the exhaust pipe 22.

[0041] Specifically, the shape of the gas gathering hood 28 is similar to that of the spreading hood 26. A gap is left between the spreading hood 26 and the gas gathering hood 28, and the wastewater is discharged from the gap, which reduces the drainage volume and makes the water curtain thinner. After meeting the neutralizer, the mixing ratio of the wastewater and the neutralizer can be made more appropriate, thereby improving the neutralization effect without wasting the neutralizer. At the same time, the gas discharged from the blowing pipe 4 and the gas generated by the reaction enter the exhaust pipe 22 from the gas gathering hood 28 and are discharged, thereby avoiding the gas destroying the water curtain, which in turn leads to a reduction in the mixing effect of the neutralizer and wastewater.

[0042] The present invention provides an acidic wastewater treatment device based on disinfectant production. In this embodiment, the driving mechanism includes a first motor 27 fixedly mounted on the neutralization box 1 , and a first transmission pair 25 is connected between the first motor 27 and the rotating tube 24 .

[0043] The present invention provides an acidic wastewater treatment equipment based on disinfectant production. Due to the poor fluidity of limestone powder, the amount of limestone powder extracted by the negative pressure in the blowing pipe 4 is less than the amount of air generating the negative pressure, so the amount of wastewater introduced each time needs to be controlled within a range compatible with the amount of neutralizer. Therefore, the feeding efficiency is reduced and the neutralization time is prolonged. To solve this problem, in this embodiment, an air chute assembly 8 is also installed in the neutralization box 1, and the air chute assembly 8 includes an installation cavity 84 opened in the neutralization box 1, and a second blower 81 is fixedly installed inside the installation cavity 84, and one end of the second blower 81 is connected to a blowing air duct 82, and one end of the blowing air duct 82 is connected to the interior of the discharge pipe 13, and a plurality of air inlet holes 83 connected to the installation cavity 84 are opened on the side of the neutralization box 1.

[0044] Specifically, one end of the blowing duct 82 is directed toward the premixing chamber 10, and the second blower 81 is started. The second blower 81 draws in external air and passes it into the discharge pipe 13 through the blowing duct 82, so that the material particles are filled with air, forming a fluidized state (similar to liquid fluidity). The fluidized neutralizer flows naturally downward in the inclined discharge pipe 13 by gravity. After the neutralizer flows into the blowing pipe 4, it is blown out from the top by the larger airflow in the blowing pipe 4. This structure can greatly improve the feeding efficiency.

[0045] The present invention provides an acidic wastewater treatment equipment based on disinfectant production. In order to make the neutralizer more evenly distributed after being sprayed from the blowing pipe 4 and improve the mixing effect, in this embodiment, the blowing pipe 4 is located at one end of the premixing chamber 10 and is equipped with a spraying mechanism 7. The spraying mechanism 7 includes a spraying funnel 73 rotatably mounted at the end of the blowing pipe 4. The spraying funnel 73 is funnel-shaped. The inner side wall of the spraying funnel 73 is fixedly connected to a plurality of inclined second guide strips 72. The inner side wall of the blowing pipe 4 is fixed with a plurality of inclined second guide strips 72. It is connected to a second fixed frame 75, on which a connecting rod 74 is slidably mounted. The top of the connecting rod 74 is fixedly connected to a blocking ball 71. Initially, the blocking ball 71 and the spray funnel 73 are tangent, and several of the second material guide bevels 72 are all below the blocking ball 71. The blocking ball 71 can seal the spray funnel 73 to prevent waste water from splashing into the inside of the blowing tube 4. The bottom end of the connecting rod 74 is fixedly connected to a stop head 76, which is used to prevent the connecting rod 74 from falling off from the second fixed frame 75.

[0046] Specifically, the second material guiding strips 72 are inclined relative to the vertical plane, thereby forming a plurality of inclined air ducts. When the airflow passes through the inclined air ducts, it can exert a lateral force on the air ducts, thereby causing the airflow to drive the spray funnel 73 to rotate. Under the action of centrifugal force, the neutralizer is sprayed over a larger area and dispersed more widely, ultimately causing the wastewater and neutralizer to meet on the side wall of the premixing chamber 10 and flow together into the reaction chamber 14.

[0047] The bottom end of the stopper 76 is set to be conical. When the airflow carries the neutralizer upward, the conical stopper 76 can separate the airflow and the neutralizer in the middle, so that the neutralizer is dispersed outwards, so that it can be subsequently diffused outwards from the spray funnel 73, thereby increasing the diffusion range of the neutralizer.

[0048] At the same time, after the airflow hits the blocking ball 71, the blocking ball 71 can float, thereby forming a gap between the blocking ball 71 and the spray funnel 73. The airflow and neutralizer are sprayed out from the gap. According to the Coanda effect, the airflow flows along the surface of the blocking ball 71 and is eventually discharged from the air collection hood 28 and exhaust pipe 22 above the blocking ball 71. Under the action of centrifugal force, the neutralizer is thrown by the spray funnel 73 to the side wall of the premixing chamber 10. At this time, the neutralizer and the airflow are separated, preventing the airflow from affecting the mixing of the wastewater and the neutralizer.

[0049] After the first blower 3 stops working, the blocking ball 71 will fall onto the spray funnel 73, blocking the blowing pipe 4, preventing the residual waste water in the feeding pipe 21 from falling into the blowing pipe 4 and then damaging the first blower 3.

[0050] The present invention provides an acid wastewater treatment equipment based on disinfectant production. After the first blower 3 stops working, a large amount of neutralizer still exists in the blowing pipe 4, which will fall into the inside of the blowing pipe 4 and may be sucked back into the first blower 3, causing damage to the first blower 3. Therefore, in this embodiment, the inside of the blowing pipe 4 is also equipped with an anti-backflow mechanism 6, and the anti-backflow mechanism 6 includes a wind collecting cover 68 fixedly installed inside the blowing pipe 4, and the top of the wind collecting cover 68 is connected to A connecting tube 67 is provided with a spherical head 63 at the top thereof, and a plurality of air outlet holes 65 are provided on the spherical head 63. A sliding cylinder 66 is slidably mounted on the connecting tube 67. The outer diameter of the sliding cylinder 66 is the same as the inner diameter of the blowing tube 4. A block 62 is fixedly connected to the inner side surface of the sliding cylinder 66. A conical surface 64 is provided inside the block 62. Initially, the conical surface 64 is tangent to the spherical head 63, and the plurality of air outlet holes 65 are all located below the block 62.

[0051] Specifically, when the blow tube 4 is ventilated, air flows into the sliding cylinder 66 through the air outlet 65. The airflow lifts the block 62 and the sliding cylinder 66, creating a gap between the block 62 and the spherical head 63. Air flows out from the gap. After the first blower 3 stops working, the sliding cylinder 66 falls under the action of gravity, and the conical surface 64 becomes tangent to the spherical head 63 again, preventing the neutralizer from falling under the wind collecting cover 68, thereby protecting the first blower 3. The neutralizer that falls on the sliding cylinder 66 will be blown out during the next ventilation.

[0052] A funnel surface 61 is provided on the top of the blocking block 62 so that the neutralizing agent can be dispersed and dropped, and blown out when ventilation is performed again, thereby preventing the neutralizing agent from remaining on the sliding cylinder 66 .

[0053] The present invention provides an acidic wastewater treatment equipment based on disinfectant production. During the reaction between wastewater and neutralizer in the reaction chamber 14, in order to improve the neutralization effect of the wastewater, in this embodiment, a stirring mechanism 9 is also installed on the neutralization box 1, and the stirring mechanism 9 includes two stirring rods 92 rotatably installed inside the reaction chamber 14. A plurality of stirring plates 93 are fixedly connected to the two stirring rods 92. A second transmission pair 94 is connected between the ends of the two stirring rods 92 extending out of the neutralization box 1. A second motor 91 is fixedly installed on the side of the neutralization box 1, and the output shaft of the second motor 91 is fixedly connected to one end of a stirring rod 92.

[0054] The second motor 91 drives a stirring rod 92 to rotate, and the stirring rod 92 drives another stirring rod 92 to rotate through the second transmission pair 94. The two stirring rods 92 stir the wastewater in the reaction chamber 14 through the stirring plate 93, thereby improving the mixing effect of the wastewater and the neutralizer and improving the neutralization effect of the wastewater.

[0055] Working principle:

[0056] The neutralizer (limestone powder) is added into the storage chamber 12 through the feeding port 5, and the first blower 3 is started first. The first blower 3 extracts air and sends it into the premixing chamber 10 through the blowing pipe 4. The second blower 81 is started, and the second blower 81 pushes air into the down pipe 13 through the blowing air pipe 82, so that the material particles are filled with air to form a fluidized state. The fluidized neutralizer naturally flows downward in the inclined down pipe 13. After the neutralizer flows into the blowing pipe 4, it is blown into the spray funnel 73 by the air in the blowing pipe 4. The airflow blows up the blocking ball 71, and the airflow entrains the neutralizer and discharges it from the air duct. Since the air duct is inclined, the airflow can give the air duct a lateral force when passing through the inclined air duct, so that the airflow drives the spray funnel 73 to rotate. Under the action of centrifugal force, the neutralizer is thrown out and the neutralizer is discharged. It disperses, and after the neutralizer is sprayed into the premixing chamber 10, the wastewater flows from the feeding pipe 21 into the rotating pipe 24 and is sprayed out from the sprinkling cover 26. At the same time, the driving mechanism drives the rotating pipe 24 and the sprinkling cover 26 to rotate, and the outer wastewater flows out along the inclined water channel between the first guide strips 29 and is thrown onto the side wall of the premixing chamber 10 by centrifugal force, so that the wastewater is dispersed and sprayed out in the form of a water curtain. Then the neutralizer and the wastewater meet, the neutralizer dissolves in the wastewater, and then flows into the reaction chamber 14 together for full reaction, so that the wastewater and the neutralizer are fully mixed, and the neutralizer collides with the water curtain, which can break up the agglomerated neutralizer, and under the impact of the subsequent water flow, the generated CaSO4 will quickly fall into the reaction chamber 14, and the subsequent neutralizer will not be wrapped by the CaSO4, thereby avoiding the waste of neutralizer;

[0057] In the reaction chamber 14, the second motor 91 drives a stirring rod 92 to rotate, and the stirring rod 92 drives another stirring rod 92 to rotate through the second transmission pair 94. The two stirring rods 92 stir the wastewater in the reaction chamber 14 through the stirring plate 93, thereby improving the mixing effect of the wastewater and the neutralizer, and improving the neutralization effect of the wastewater.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
