Description

TECHNICAL FIELD

[0001] The present application belongs to the field of waste liquid treatment, and particularly relates to a waste liquid treatment spraying system and a waste liquid treatment spraying method. BACKGROUND

[0002] With the increasing strictness of the national environmental protection standards, the demand for wastewater treatment has also risen sharply. This growth in demand stems from the increasing awareness of water resource protection and the urgent need to maintain ecological balance. Wastewater treatment is no longer a matter of casual discharge, but needs to be directed to specialized treatment facilities for careful and scientific treatment. The treatment process is diversified, covering physical, chemical and biological methods, among which sedimentation, filtration and chemical reaction are several common technical means.

[0003] Specifically, the nature of the wastewater determines the applicable treatment method. For example, wastewater containing suspended solids may be more suitable for removing impurities through sedimentation or filtration; while wastewater containing dissolved pollutants may need to be purified by chemical reaction. For wastewater that must be treated by chemical means, it is usually sent to a specially designed reaction kettle. In this closed environment, specific chemical reagents are added to the sewage to promote the decomposition or transformation of pollutants, thereby achieving the purpose of purifying water quality.

[0004] However, some chemical reactions release gas, and the accumulation of these gases can increase the internal pressure of the reaction kettle. For many standard designed reaction kettles, the built-in spraying system does not take into account the stable operation requirements under high pressure conditions. Therefore, under high pressure conditions, the spraying system is prone to failure, such as leakage, blockage or performance degradation, which not only affects the efficiency of wastewater treatment, but also may cause secondary pollution to the surrounding environment. SUMMARY

[0005] The purpose of the present application is to provide a waste liquid treatment spraying system and a waste liquid treatment spraying method, which can add liquid for treating waste liquid, and the generated high pressure will not damage the equipment.

[0006] The technical scheme is as follows:

[0007] The waste liquid treatment spraying system comprises a reaction kettle, a sealing assembly, a liquid inlet pipe and a spraying assembly. The reaction kettle is provided with a spraying port, the sealing assembly is installed on the spraying port, the liquid inlet pipe penetrates through the sealing assembly, the sealing assembly divides the liquid inlet pipe into two sections, one section is located outside the reaction kettle and is a first section, and the other section is located inside the reaction kettle and is a second section, and the spraying assembly is installed on the port of the second section. A plurality of spraying positions are arranged in the spraying assembly, a first liquid port is arranged on the inner side of the spraying position, a spraying block is slidably arranged in the spraying position, a second liquid port is arranged on the spraying block, and liquid is sprayed out through the first liquid port and the second liquid port. When the gas pressure of the reaction kettle increases, the gas pressure acts on the spraying block, so that the spraying block slides towards the first liquid port and blocks the first liquid port.

[0008] In one embodiment, a flow channel is formed in the spraying assembly, the first liquid port communicates with the flow channel, the second liquid port is located in the first liquid port in the sliding direction of the spraying block, and the first liquid port and the second liquid port are blocked after the spraying block slides towards the first liquid port.

[0009] In one embodiment, the spraying assembly further comprises a shell, an inner sleeve, an end cover and a sealing ring. One end of the shell is provided with an installation space with an opening, and the other end is provided with a third liquid port. The third liquid port communicates with the installation space. The sealing ring and the inner sleeve are installed in the installation space. The end cover is installed at the opening of the installation space and holds the inner sleeve, so that the inner sleeve holds the sealing ring at the bottom of the shell. The inner sleeve forms the spraying position, the first liquid port is arranged at the bottom of the spraying position, and the space formed by the bottom of the installation space, the sealing ring and the wall of the inner sleeve is the flow channel.

[0010] In one embodiment, a plurality of avoiding holes corresponding to the spraying position are arranged on the end cover, and a positioning column protruding towards the inner sleeve is arranged on the end cover. A groove matched with the positioning column is arranged on the inner sleeve. The positioning column and the groove are matched to limit the spraying position corresponding to the avoiding hole. The inner diameter of the avoiding hole is smaller than the outer diameter of the spraying block to limit the spraying block in the spraying position.

[0011] In one embodiment, one end of the spraying block towards the bottom of the spraying position is an inner end, and the other end away from the spraying position is an outer end. The second liquid port expands from the outer end to the inner end. An annular recess is arranged on the outer end along the second liquid port, so that the recess is pressed to close the side of the second liquid port at the outer end.

[0012] In one of the embodiments, the sealing assembly comprises a base, a rubber pad and a sealing ring; the base is provided with a through hole, the base is installed on the spray port and the through hole is opposite to the spray port, and the liquid inlet pipe passes through the through hole; the sealing ring is installed in the through hole and abuts against the liquid inlet pipe on the inner side and abuts against the wall of the through hole on the outer side, and the rubber pad is sleeved on the liquid inlet pipe and installed on the upper side of the through hole.

[0013] In one of the embodiments, a tapered ring groove is formed on the side of the sealing ring facing the spray port, the opening size of the tapered ring groove is larger than the bottom size, under the action of air pressure, the two side walls of the tapered ring groove are forced to expand outward, so that the extrusion force between the sealing ring and the through hole and between the sealing ring and the liquid inlet pipe is increased.

[0014] In one of the embodiments, the second section of the liquid inlet pipe is provided with a corner, so that the second liquid port of the spray assembly is inclined to the side wall of the reaction kettle; a rotating driving assembly is installed on the upper end of the sealing assembly, the second section of the liquid inlet pipe passes through the rotating driving assembly, the rotating driving assembly drives the liquid inlet pipe to rotate, and in turn drives the spray assembly to rotate.

[0015] In one of the embodiments, a first bearing is further installed in the through hole, the first bearing is sleeved on the liquid inlet pipe and located between the rubber pad and the sealing ring; the rotating driving assembly comprises a driving motor, a transmission group and a transmission wheel, the transmission wheel is sleeved on the first section of the liquid inlet pipe, the driving motor drives the transmission wheel to rotate through the transmission group, and in turn drives the liquid inlet pipe to rotate.

[0016] The waste liquid treatment spray method uses the waste liquid treatment spray system, and comprises the following steps:

[0017] The waste liquid to be treated is added into the reaction kettle;

[0018] The liquid for treating the waste liquid is added through the liquid inlet pipe and sprayed into the reaction kettle through the spray assembly;

[0019] The addition of the liquid for treating the waste liquid is stopped, the reaction of the waste liquid generates gas, and the gas pushes the spray block to move to block the first liquid port.

[0020] The technical solution provided by the application has the following advantages and effects:

[0021] When waste liquid needs to be treated, it is loaded into the reactor, and then a liquid for treating the waste liquid, such as a reaction reagent, is introduced through the inlet pipe. The liquid for treating the waste liquid is then sprayed into the reactor through the inlet pipe and the spray assembly, and can be shut off after a predetermined volume is reached. Specifically, the liquid for treating the waste liquid first passes through the inlet pipe, then through the first liquid port to the spray position. Due to the obstruction of the spray block, it then passes through the second liquid port and is finally sprayed into the reactor. After the waste liquid reacts in the reactor, the generated gas fills the entire reactor, causing the gas pressure inside the reactor to be greater than atmospheric pressure. Due to the pressure difference, the spray block is moved inward by the gas pressure, causing the spray block to come into close contact with the first liquid port, thereby sealing the first liquid port. The high-pressure gas inside the reactor will not be conducted outward through the spray assembly, thus protecting other equipment from high-pressure damage or eliminating the need to select high-pressure resistant equipment, thereby saving costs. The sealing assembly is installed at the spray port of the reactor and works in conjunction with the inlet pipe, so the high-pressure gas inside the reactor cannot escape outward through the spray port.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present application, specific embodiments of the present application will be described in more detail below with reference to the accompanying drawings.

[0036] Unless specifically stated or otherwise defined, the terms "first", "second" and the like used herein are merely used to distinguish one element from another, and do not necessarily indicate the quantity or order of the elements. Unless specifically stated or otherwise defined, the term "and / or" used herein includes any and all combinations of one or more of the associated listed items. It should be noted that "fixed to", "connected to" herein can be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0037] As Figures 1 to 5As shown, the waste liquid treatment spraying system comprises a reaction kettle 10, a sealing assembly 30, a liquid inlet pipe 20 and a spraying assembly 40; the reaction kettle 10 is provided with a spraying port 11, the sealing assembly 30 is installed on the spraying port 11, the liquid inlet pipe 20 penetrates through the sealing assembly 30, the sealing assembly 30 divides the liquid inlet pipe 20 into two sections, one section outside the reaction kettle 10 is a first section 21, and the other section inside the reaction kettle 10 is a second section 22, and the spraying assembly 40 is installed on the port of the second section 22; a plurality of spraying positions 421 are arranged in the spraying assembly 40, a first liquid port 422 is arranged on the inner side of the spraying position 421, and a spraying block 46 is slidingly installed on the spraying position 421, and a second liquid port 461 is further arranged on the spraying block 46, and liquid is sprayed out through the first liquid port 422 and the second liquid port 461; when the gas pressure of the reaction kettle 10 increases, the gas pressure acts on the spraying block 46, so that the spraying block 46 slides towards the first liquid port 422 and blocks the first liquid port 422.

[0038] When waste liquid needs to be treated, the waste liquid is filled into the reaction kettle 10, and then the liquid for treating waste liquid, such as a reaction reagent, is introduced into the reaction kettle 10 through the liquid inlet pipe 20; the liquid for treating waste liquid is finally sprayed into the reaction kettle 10 through the liquid inlet pipe 20 and the spraying assembly 40, and can be closed after reaching a predetermined amount. Specifically, the liquid for treating waste liquid first passes through the liquid inlet pipe 20, then enters the spraying position 421 through the first liquid port 422, and then finally sprays into the reaction kettle 10 through the second liquid port 461 due to the blockage of the spraying block 46. After the waste liquid reacts in the reaction kettle 10, the generated gas fills the entire reaction kettle 10, so that the gas pressure in the reaction kettle 10 is greater than the atmospheric pressure, and due to the pressure difference, the spraying block 46 is moved by the gas pressure to the inside of the spraying position 421, so that the spraying block 46 is in close contact with the first liquid port 422, thereby blocking the first liquid port 422, and the high-pressure gas in the reaction kettle 10 cannot be conducted outward through the spraying assembly 40, so that other equipment is protected from high pressure damage, or high-pressure-resistant equipment does not need to be selected, thereby saving costs. The sealing assembly 30 is installed on the spraying port 11 of the reaction kettle 10, and then cooperates with the liquid inlet pipe 20, so that the high-pressure gas in the reaction kettle 10 cannot overflow outward through the spraying port 11.

[0039] It should be noted that the high pressure described in the present scheme is not an absolute high pressure, but a gas pressure higher than the atmospheric pressure, which is referred to as high pressure in the present scheme.

[0040] See Figure 9 and Figure 10As shown, the spray assembly 40 is formed with a flow channel 45, the first liquid port 422 communicates with the flow channel 45, and the second liquid port 461 is staggered with the first liquid port 422 in the sliding direction of the spray block 46. The first liquid port 422 is blocked by the second liquid port 461 after the spray block 46 slides to the first liquid port 422. The liquid for treating waste liquid first enters the flow channel 45 through the liquid inlet pipe 20, and then flows from the first liquid port 422 to the spray site 421 through the flow channel 45. Since the second liquid port 461 is staggered with the first liquid port 422 in the sliding direction of the spray block 46, the spray block 46 is in contact with the first liquid port 422 under the action of the gas pressure in the reaction kettle 10, and the first liquid port 422 and the second liquid port 461 are blocked, so the liquid for treating waste liquid cannot pass through the first liquid port 422 and the second liquid port 461, that is, it cannot be sprayed from the spray assembly 40; at the same time, the gas in the reaction kettle 10 cannot enter the flow channel 45 through the second liquid port 461 and the first liquid port 422, so that the gas in the reaction kettle 10 will not impact other components in the spray assembly 40, as well as the liquid inlet pipe 20 and other accessories connected to the liquid inlet pipe 20, so it is more conducive to maintain the entire spray system.

[0041] See Figure 10 As shown, the first liquid port 422 is provided with a protrusion at one end facing the spray site 421. When the spray block 46 slides to contact the protrusion, a small area of contact is formed, that is, the force area is small. Therefore, under the same force of the spray block 46, the contact between the spray block 46 and the boss has a larger pressure, so the sealing effect of the spray block 46 and the boss is better. The surface of the boss is in the form of a circular arc. In other embodiments, a planar structure or a conical structure can be used, or a hemispherical ring structure can be used. The essence is to ensure that there is a protruding part, and the contact area of the protruding part with the spray block 46 is much smaller than the area of the side of the spray block 46 facing the reaction kettle 10.

[0042] See Figures 7 to 9As shown, the spray assembly 40 further includes a housing 41, an inner sleeve 42, an end cap 43, and a sealing ring 44; one end of the housing 41 is provided with an installation space with an opening, and the other end is provided with a third liquid port 411, which communicates with the installation space; the sealing ring 44 and the inner sleeve 42 are installed in the installation space, and the end cap 43 is installed at the opening of the installation space and presses the inner sleeve 42 until the inner sleeve 42 presses the sealing ring 44 at the bottom of the housing 41; the inner sleeve 42 opens the spray position 421, and the first liquid port 422 is opened at the bottom of the spray position 421; the space formed by the bottom of the installation space, the sealing ring 44, and the wall of the inner sleeve 42 is the flow channel 45. The inlet pipe 20 is connected to the third liquid port 411. The waste liquid enters the flow channel 45 through the third liquid port 411. The flow channel 45 is the space formed by the outer shell 41, the inner component 42, and the sealing ring 44. Since the sealing ring 44 is in close contact with the outer shell 41 and the inner component 42, the flow channel 45 forms a closed space. The liquid can only enter or exit through the first liquid port 422 or the third liquid port 411, thus ensuring the airtightness of the spray assembly 40. Since the inner component 42 is provided with multiple spray positions 421, there are multiple first liquid ports 422 on the inner component 42. Each first liquid port 422 is connected to the flow channel 45. The flow channel 45 formed by this solution can communicate with multiple first liquid ports 422, so it is not necessary to open separate channels to correspond one-to-one with multiple first liquid ports 422, thereby reducing the design difficulty and saving production costs.

[0043] See Figure 7 and Figure 9 As shown, a mounting platform is provided on the outside of the outer casing 41, with the third liquid port 411 located in the middle of the mounting platform. The liquid inlet pipe 20 is threaded into the mounting platform to connect the liquid inlet pipe 20 to the spray assembly 40. In this embodiment, the liquid inlet pipe 20 is directly used for liquid inlet. In other embodiments, another flexible pipe can pass through the liquid inlet pipe 20 and then connect with the third liquid port 411.

[0044] See Figure 7 and Figure 9 As shown, when the inner component 42 and the sealing ring 44 are installed in the installation space of the outer shell 41, one end of the inner component 42 protrudes from the installation space. When the end cap 43 is installed, the end cap 43 is pressed against the inner component 42 by the tight fit between the end cap 43 and the outer shell 41, thus giving the inner component 42 a pressure, which causes the inner component 42 and the sealing ring 44 to be squeezed together, ensuring the airtightness of the flow channel 45.

[0045] The sealing ring 44 is placed along the edge of the mounting space of the outer shell 41 during installation, so as to ensure that the space of the flow channel 45 is large enough. In addition, the cross section of the sealing ring 44 can be circular, rectangular or trapezoidal, and is rectangular in the embodiment.

[0046] See Figures 7 to 10 As shown in the figure, the end cover 43 is provided with a plurality of avoiding holes 431 corresponding to the spraying positions 421, and is provided with a positioning column 432 protruding towards the inner sleeve 42. The inner sleeve 42 is provided with a groove 423 matched with the positioning column 432. The positioning column 432 cooperates with the groove 423 to limit the spraying positions 421 corresponding to the avoiding holes 431. The inner diameter of the avoiding hole 431 is smaller than the outer diameter of the spraying block 46, so as to limit the spraying block 46 in the spraying position 421. The avoiding hole 431 can not hinder the liquid outlet of the first liquid port 422, and can also allow the gas in the reaction kettle 10 to act on the spraying block 46. The inner diameter of the avoiding hole 431 is smaller than the outer diameter of the spraying block 46, so that the spraying block 46 is blocked when it encounters the side edge of the avoiding hole 431 during outward sliding, thereby playing a limiting role. In addition, since the spraying position 421 on the inner sleeve 42 corresponds to a spraying block 46, it is also necessary to ensure that each spraying position 421 corresponds to at least one avoiding hole 431. Therefore, the end cover 43 is provided with a positioning column 432, and the inner sleeve 42 is provided with a groove 423. Through the limiting action of the positioning column 432 and the groove 423, it is ensured that each spraying position 421 corresponds to at least one avoiding hole 431. The positioning column 432 of the scheme is provided with two, and the corresponding groove 423 is also provided with two. In other embodiments, one positioning column 432 can be used, but the positioning column 432 cannot be arranged on the axis of the end cover 43. Three or other numbers of positioning columns 432 can also be used.

[0047] In other embodiments, the positioning column 432 is arranged on the inner sleeve 42, and the groove 423 is arranged on the end cover 43. Alternatively, the inner sleeve 42 can be provided with both the positioning column 432 and the groove 423, and the end cover 43 is provided with the groove 423 and the positioning column 432 correspondingly.

[0048] See Figure 7 and Figure 9 As shown in the figure, the end cover 43 is provided with an inner thread, and the outer shell 41 is provided with an outer thread. The end cover 43 and the outer shell 41 are connected through thread cooperation, so that the compression force of the inner sleeve 42 can be determined by the degree of screwing. In other embodiments, the end cover 43 and the outer shell 41 can be connected through buckling.

[0049] See Figure 10 and Figure 11As shown, the spray block 46 has an inner end 462 at one end of the bottom of the spray site 421 and an outer end 463 at the other end of the spray site 421; the second liquid port 461 expands from the outer end 463 to the inner end 462, and the outer end 463 is provided with an annular recess 464 along the second liquid port 461, so that the recess 464 is pressed to close the side of the second liquid port 461 at the outer end 463. The position of the recess 464 can close the second liquid port 461 when high pressure is generated in the reactor 10, so as to prevent high-pressure gas from passing through the first liquid port 422, thereby providing a second layer of protection. The side of the recess is used for stress, and since the inclination is arranged, the stress on the outer side is directed to the second liquid port 461 when pressed, thereby closing the second liquid port 461. The second liquid port 461 expands at the inner end 462, which can ensure the collection of liquid and also provide a pressurizing effect. The inner end 462 of the second liquid port 461 is expanded, but the position of the first liquid port 422 is also staggered.

[0050] See Figure 10 and Figure 11 As shown, the side wall of the spray block 46 is provided with a sealing protrusion 465, which is fitted with the side wall of the spray site 421, so that the spray site 421 is blocked into two areas, i.e. the liquid for treating waste liquid can only flow out through the second liquid port 461, and gas cannot pass through the matching position between the spray block 46 and the spray site 421. The cross section of the sealing protrusion 465 is semicircular. In this embodiment, two sealing protrusions 465 are arranged in parallel, and the arrangement of two sealing protrusions 465 can further ensure the sealing between the sealing block and the spray site 421. In other embodiments, a plurality of sealing protrusions 465 can also be arranged

[0051] The spray block 421 is made of rubber material and has elasticity as a whole, so that a gap can be avoided between the spray block 421 and the spray site 421 when sliding. The material of the silicone rubber deforms more when contacting the first liquid port 422, which is more conducive to fitting on the first liquid port 422 and achieving better sealing effect. Of course, in other embodiments, other materials such as silicone rubber or a layer of flexible material can be added to the surface of the hard plastic.

[0052] In some embodiments, the spray block 421 has high requirements for corrosion resistance, and can be made of tetrafluoroethylene material, which can greatly improve the corrosion resistance and is conducive to improving the stability of the whole system.

[0053] See Figure 3 and Figure 6As shown, the sealing assembly 30 comprises a base 31, a rubber pad 32 and a sealing ring 33; the base 31 is provided with a through hole 311, the base 31 is installed on the spray port 11 and the through hole 311 is opposite to the spray port 11, and the liquid inlet pipe 20 passes through the through hole 311; the sealing ring 33 is installed in the through hole 311 and abuts against the liquid inlet pipe 20 on the inner side and abuts against the wall of the through hole 311 on the outer side, the rubber pad 32 is sleeved on the liquid inlet pipe 20 and is installed on the upper side of the through hole 311. The sealing ring 33 is attached to the side wall of the liquid inlet pipe 20, the other end is attached to the inner wall of the through hole 311, and the base 31 is fixedly connected to the spray port 11, so that the high-pressure gas in the reaction kettle 10 is blocked when encountering the sealing ring 33, and cannot leak out through the spray port 11. Moreover, the installation of the rubber pad 32 ensures that external dust objects cannot easily enter the through hole 311, avoiding the problem of leakage of the sealing ring 33 due to dust, and effectively slowing down the aging of the sealing ring 33.

[0054] In addition, as shown in Figure 6 As shown, the through hole 311 in the base 31 is further provided with a protruding blocking table 312, and the sealing ring 33 is installed below the blocking table 312, so that when the sealing ring 33 is affected by the gas pressure and moves, it will be blocked by the blocking table 312 and finally be stuck in a fixed position.

[0055] In this embodiment, the blocking table 312 is arranged around the inner wall of the through hole 311, which can ensure that each point in contact with the sealing ring 33 is balanced, so that the sealing ring 33 is less likely to deform, avoiding the occurrence of gaps between the contact position of the sealing ring 33 and the through hole 311, thereby preventing gas leakage. In other embodiments, multiple blocking tables 312 can be arranged at intervals on the inner wall of the through hole 311, which can also have a good blocking effect.

[0056] As shown in Figure 6 As shown, the sealing ring 33 is provided with a tapered ring groove 331 on the side facing the spray port 11, and the opening size of the tapered ring groove 331 is larger than the bottom size. Under the action of gas pressure, the two side walls of the tapered ring groove 331 are forced to expand outward, increasing the extrusion force between the sealing ring 33 and the through hole 311 and between the sealing ring 33 and the liquid inlet pipe 20. This arrangement forms two inclined walls on both sides of the tapered ring groove 331. When the gas pressure acts on the inclined walls, the two inclined walls move outward, i.e. move to the side of the liquid inlet pipe 20 and to the inner wall of the through hole 311 of the base 31, and are extruded, so that the extrusion force increases with the increase of the gas pressure during sealing, the sealing effect is better, and the problem of easy failure of the sealing ring 33 due to excessive pressure is cleverly overcome.

[0057] In this embodiment, the conical ring groove 331 structure is adopted, and in other embodiments, other opening modes such as rectangular and elliptical can also be adopted.

[0058] In this embodiment, as shown in Figure 6 A rubber pad 35 is arranged between the base 31 and the spray port 11 to avoid gas leakage caused by the gap between the base 31 and the spray port 11 when they are matched.

[0059] As shown in Figures 3 to 6 The second section 22 of the liquid inlet pipe 20 is provided with a corner 23, so that the second liquid port 461 of the spray assembly 40 is inclined towards the side wall of the reactor 10; the upper end of the sealing assembly 30 is provided with a rotating drive assembly 50, the second section 22 of the liquid inlet pipe 20 passes through the rotating drive assembly 50, and the rotating drive assembly 50 drives the liquid inlet pipe 20 to rotate, thereby driving the spray assembly 40 to rotate.

[0060] Since the second end of the liquid inlet pipe 20 is provided with the corner 23, the position directly facing the spray assembly 40 is not towards the bottom of the reactor 10, but is located on the side wall of the reactor 10, so when the liquid pressure entering the liquid inlet pipe 20 is low, the initial speed of the liquid finally coming out of the second liquid port 461 is low, that is, after coming out of the second liquid port 461, the liquid begins to fall downwards under the influence of gravity, such as liquid for treating waste liquid. If the liquid pressure entering the liquid inlet pipe 20 is high, the initial speed of the liquid finally coming out of the second liquid port 461 is high, and in addition, the second liquid port 461 expands from the outer end 463 to the inner end 462, which plays a role of pressure increase, so the liquid can be directly sprayed onto the side wall of the reactor 10, at this time, the effect of washing the reactor 10 can be achieved.

[0061] As shown in Figure 4 and Figure 5 The liquid inlet pipe 20 is driven to rotate by the transmission drive assembly, so the spray assembly 40 can also rotate finally, and under the action of liquid with high pressure, the spray assembly 40 can be driven by the transmission drive assembly to make the liquid sprayed by the spray assembly 40 wash around the side wall of the reactor 10, at this time, the liquid can be clean water, cleaning liquid, etc.

[0062] In this embodiment, the bending angle of the liquid inlet pipe 20 is 135 degrees, at this time, when the reactor 10 is placed horizontally, the angle between the bent part and the horizontal plane is 45 degrees, which can ensure that the liquid has a downward angle and also has an initial speed on the horizontal plane, so that liquid with a certain pressure can be sprayed onto the side wall of the reactor 10. In other embodiments, the bending angle of the liquid inlet pipe 20 can be 120 degrees, at this time, the angle between the bent part and the horizontal plane is 60 degrees.

[0063] As shown in Figure 7As shown, in particular in this embodiment, the liquid inlet pipe 20 is a whole, and then is bent. In other embodiments, the liquid inlet pipe 20 can be in multiple sections, such as a straight pipe plus a bent pipe section to form a liquid inlet pipe 20.

[0064] See Figure 6 As shown, in particular, the through hole 311 is further provided with a first bearing 34, the first bearing 34 is sleeved on the liquid inlet pipe 20, and is located between the rubber pad 32 and the sealing ring 33. The first bearing 34 of the through hole 311 is installed above the blocking table 312, and is clamped in this position. Since the liquid inlet pipe 20 needs to be rotated, through the bearing of the first bearing 34, the function of limiting and facilitating rotation can be achieved. See Figure 6 As shown, the rubber pad 32 has a protruding structure which is clamped in the through hole 311 and is close to the upper surface of the first bearing 34. This arrangement can provide an upper limit for the first bearing 34, and can also prevent dust from entering the first bearing 34, thereby ensuring the rotation effect of the first bearing 34.

[0065] See Figure 3 And Figure 6 As shown, the rotating drive assembly 50 includes a drive motor 51, a transmission group 52 and a transmission wheel 53, the transmission wheel 53 is sleeved on the first section 21 of the liquid inlet pipe 20, the drive motor 51 drives the transmission wheel 53 to rotate through the transmission group 52, thereby driving the liquid inlet pipe 20 to rotate. At this time, the transmission group 52 is a gear set structure, which drives the transmission wheel 53 to rotate through the output shaft of the drive motor 51, and finally drives the liquid inlet pipe 20 to rotate.

[0066] See Figure 3 And Figure 6 As shown, the transmission group 52 includes a protective shell on the outer side, and the protective shell is provided with a second bearing 54 on both upper and lower sides matched with the liquid inlet pipe 20. Through the action of the second bearing 54, the rotating position of the gear set and the transmission wheel 53 is not easy to change, thereby ensuring the stability of the transmission. In addition, the protective shell and the sealing assembly 30 are fixedly connected to complete the installation and fixation.

[0067] The waste liquid treatment spraying method using the waste liquid treatment spraying system includes the following steps:

[0068] The reaction kettle 10 is added with the waste liquid to be treated;

[0069] The liquid for treating waste liquid is added through the liquid inlet pipe 20, and is sprayed into the reaction kettle 10 through the spraying assembly 40;

[0070] The addition of the liquid for treating waste liquid is stopped, the waste liquid reaction produces gas, and the spraying block 46 is pushed to move to block the first liquid port 422.

[0071] The above embodiments are also not exhaustive enumeration based on the present application, in addition to which, there can be a plurality of other embodiments not listed. Any substitution and improvement made without violating the concept of the present application is within the scope of protection of the present application.
