Description

Technical Field

[0001] The invention belongs to the field of waste liquid treatment, and in particular relates to a waste liquid treatment spraying system and a waste liquid treatment spraying method. Background Art

[0002] As the country's environmental protection standards become increasingly stringent, the demand for wastewater treatment has also risen sharply. This growth in demand stems from the increased awareness of water resource protection and the urgent need to maintain ecological balance. Wastewater treatment is no longer a matter of random discharge, but needs to be directed to specialized treatment facilities for careful and scientific treatment. The treatment process is diverse, covering a variety of methods such as physical, chemical and biological, among which precipitation, filtration and chemical reaction are several common technical means.

[0003] Specifically, the nature of wastewater determines the treatment method that is suitable for it. For example, wastewater containing suspended matter may be more suitable for removing impurities through sedimentation or filtration; while wastewater containing soluble pollutants may require chemical reactions to achieve purification. For wastewater that must be treated by chemical means, it is usually sent to a specially designed reactor. 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 gases, and the accumulation of these gases will lead to an increase in the pressure inside the reactor. For many standard-design reactors, their built-in spray systems do not take into account the need for stable operation under high-pressure environments. Therefore, under high-pressure conditions, the spray system is prone to failures, such as leakage, blockage, or performance degradation, which not only affects the efficiency of wastewater treatment, but also may cause the risk of secondary pollution to the surrounding environment. Summary of the invention

[0005] The object of the present invention is to provide a waste liquid treatment spray system and a waste liquid treatment spray method, in which liquid for treating waste liquid can be added and the generated high pressure will not damage the equipment.

[0006] The technical solution is as follows:

[0007] A waste liquid treatment spray system comprises a reactor, a sealing component, a liquid inlet pipe and a spray component; the reactor is provided with a spray port, the sealing component is installed on the spray port, the liquid inlet pipe passes through the sealing component, the sealing component divides the liquid inlet pipe into two sections, one section is located outside the reactor as the first section, and the other section is located inside the reactor as the second section, and the spray component is installed on the port of the second section; a plurality of spray positions are arranged in the spray component, a first liquid port is opened inside the spray position, a spray block is slidably installed on the spray position, a second liquid port is also opened on the spray block, and liquid is sprayed outward through the first liquid port and the second liquid port; when the air pressure in the reactor increases, the air pressure acts on the spray block, causing the spray block to slide toward the first liquid port and block the first liquid port.

[0008] In one of the embodiments, a flow channel is formed in the spray assembly, the first liquid port is communicated with the flow channel, the second liquid port is offset from the first liquid port in the sliding direction of the spray block, and the first liquid port and the second liquid port are blocked after the spray block slides toward the first liquid port.

[0009] In one embodiment, the spray assembly further includes an outer shell, an inner sleeve, an end cover and a sealing ring; the outer shell is provided with an installation space with an opening at one end and a third liquid port at the other end, and the third liquid port is communicated 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 presses the inner sleeve until the inner sleeve presses the sealing ring at the bottom of the outer shell; the inner sleeve opens the spray position, the first liquid port is opened at the bottom of the spray 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 of the embodiments, the end cover is provided with a plurality of avoidance holes corresponding to the spraying position, and is provided with a positioning column protruding toward the inner sleeve, and the inner sleeve is provided with a groove matching the positioning column; the positioning column cooperates with the groove to limit the spraying position to correspond to the avoidance hole, and the inner diameter of the avoidance hole is smaller than the outer diameter of the spray block to limit the spray block within the spraying position.

[0011] In one embodiment, the end of the spray block facing the bottom of the spray position is the inner end, and the end facing away from the spray position is the outer end; the second liquid port expands from the outer end to the inner end, and an annular recessed position is opened at the outer end along the second liquid port, so that the recessed position is affected by air pressure, and the second liquid port is pressed and closed on one side of the outer end.

[0012] In one embodiment, the sealing assembly includes a base, a rubber pad and a sealing ring; the base has 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 the inner side abuts against the liquid inlet pipe, and the outer side abuts against the wall of the through hole, 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 conical annular groove is provided on one side of the sealing ring facing the spray port, and the opening size of the conical annular groove is larger than the bottom size. Under the action of air pressure, the two side walls of the conical annular groove are forced to expand outward, thereby increasing the extrusion pressure between the sealing ring and the through hole, and between the sealing ring and the liquid inlet pipe.

[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 toward the side wall of the reactor; a rotation drive assembly is installed at the upper end of the sealing assembly, and the second section of the liquid inlet pipe passes through the rotation drive assembly, and the rotation drive assembly drives the liquid inlet pipe to rotate, thereby driving the spray assembly to rotate.

[0016] A waste liquid treatment spraying method, using the waste liquid treatment spraying system, comprises the following steps:

[0017] Adding the waste liquid to be treated into the reactor;

[0018] Liquid for treating waste liquid is added through the liquid inlet pipe and sprayed into the reactor through the spray assembly;

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

Specifically, the liquid for treating the waste liquid first passes through the liquid inlet pipe, then enters and then enters the spray position through the first liquid port. Due to the obstruction of the spray block, it passes through the second liquid port and finally sprays into the reactor. After the waste liquid reacts in the reactor, the gas generated fills the entire reactor, causing the air pressure in the reactor to be greater than the atmospheric pressure. Due to the pressure difference, the spray block is affected by the air pressure and moves to the inside of the spray position, causing the spray block to be in close contact with the first liquid port, thereby blocking the first liquid port. The high-pressure air pressure in the reactor will not be transmitted to the outside through the spray assembly, so other equipment is protected from high-pressure damage, or high-pressure resistant equipment does not need to be selected, thereby saving costs.

DETAILED DESCRIPTION

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

[0036] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish the names and does not represent a specific quantity or order. Unless otherwise specified or defined, the term "and / or" used in this article includes any and all combinations of one or more related listed items. It should be noted that "fixed to" or "connected to" in this article can be directly fixed or connected to an element, or it can be indirectly fixed or connected to an element.

[0037] like Figures 1 to 5As shown, the waste liquid treatment spray system comprises a reactor 10, a sealing assembly 30, a liquid inlet pipe 20 and a spray assembly 40; the reactor 10 is provided with a spray port 11, the sealing assembly 30 is installed on the spray port 11, the liquid inlet pipe 20 passes through the sealing assembly 30, and the sealing assembly 30 divides the liquid inlet pipe 20 into two sections, one section is located outside the reactor 10 as a first section 21, and the other section is located inside the reactor 10 as a second section 22, and the spray assembly 40 is installed at the end of the second section 22. The spray assembly 40 is provided with a plurality of spray positions 421, the inner side of the spray position 421 is provided with a first liquid port 422, the spray position 421 is slidably mounted with a spray block 46, the spray block 46 is further provided with a second liquid port 461, and the liquid is sprayed outward through the first liquid port 422 and the second liquid port 461; when the air pressure of the reactor 10 increases, the air pressure acts on the spray block 46, causing the spray block 46 to slide toward the first liquid port 422 and block the first liquid port 422.

[0038] When waste liquid needs to be treated, the waste liquid is put into the reactor 10, and then the liquid for treating the waste liquid, such as a reaction reagent, is introduced through the liquid inlet pipe 20; the liquid for treating the waste liquid is finally sprayed into the reactor 10 through the liquid inlet pipe 20 and the spray assembly 40, and can be closed after reaching a predetermined amount. Specifically, the liquid for treating the waste liquid first passes through the liquid inlet pipe 20, then enters the spray position 421 through the first liquid port 422, and due to the obstruction of the spray block 46, it passes through the second liquid port 461 and is finally sprayed into the reactor 10. After the waste liquid reacts in the reactor 10, the generated gas fills the entire reactor 10, causing the gas pressure in the reactor 10 to be greater than the atmospheric pressure. Due to the pressure difference, the spray block 46 is affected by the gas pressure and moves to the inside of the spray position 421, causing the spray block 46 to be in close contact with the first liquid port 422, thereby blocking the first liquid port 422. The high-pressure gas pressure in the reactor 10 will not be transmitted to the outside through the spray assembly 40, so other equipment is protected from being damaged by high pressure, or there is no need to select high-pressure resistant equipment, thereby saving costs. The sealing assembly 30 is installed at the spray port 11 of the reactor 10, and then cooperates with the liquid inlet pipe 20, so the high-pressure gas in the reactor 10 cannot overflow through the spray port 11.

[0039] It should be noted that the high pressure described in this scheme is not an absolute high pressure, but is relative to the atmospheric pressure. The air pressure higher than the atmospheric pressure is called high pressure in this scheme.

[0040] See Fig. 9 and Fig.10As shown, a flow channel 45 is formed in the spray assembly 40, the first liquid port 422 is communicated with the flow channel 45, the second liquid port 461 is offset from the first liquid port 422 in the sliding direction of the spray block 46, and the first liquid port 422 and the second liquid port 461 are blocked after the spray block 46 slides toward 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 position 421 through the flow channel 45. Since the second liquid port 461 is misaligned with the first liquid port 422 in the sliding direction of the spray block 46, when the spray block 46 slides to fit on the first liquid port 422 under the action of the air pressure of the reactor 10, the first liquid port 422 and the second liquid port 461 are blocked, so the liquid for treating the waste liquid cannot pass through the first liquid port 422 and the second liquid port 461, that is, it cannot be sprayed out from the spray assembly 40; at the same time, the gas in the reactor 10 cannot enter the flow channel 45 through the second liquid port 461 and the first liquid port 422, so the gas in the reactor 10 will not cause impact on 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 the maintenance of the entire spray system.

[0041] See Fig.10 As shown, a protrusion is provided at one end of the first liquid inlet 422 toward the spray position 421. When the spray block 46 slides and contacts the protrusion, a small contact area is formed, that is, the force area is small. Therefore, under the same force condition of the spray block 46, the contact between the spray block 46 and the protrusion has a greater pressure, so the sealing effect between the spray block 46 and the protrusion is better. The surface of the protrusion here is in an arc shape. In other embodiments, a plane structure, a conical structure, or a hemispherical ring structure can be used. The essence is to ensure that there is a protrusion, and the contact area between the protrusion and the spray block 46 is much smaller than the area of ​​the spray block 46 facing the reactor 10.

[0042] See Figures 7 to 9As shown, the spray assembly 40 also includes an outer shell 41, an inner sleeve 42, an end cover 43 and a sealing ring 44; the outer shell 41 is provided with an installation space with an opening at one end, and a third liquid port 411 is provided at the other end, and the third liquid port 411 is communicated with the installation space; the sealing ring 44 and the inner sleeve 42 are installed in the installation space, and the end cover 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 outer shell 41; the inner sleeve 42 is provided with the spray position 421, and the first liquid port 422 is provided at the bottom of the spray position 421, and the space formed by the bottom of the installation space and the sealing ring 44 and the wall of the inner sleeve 42 is the flow channel 45. The liquid inlet pipe 20 is connected to the third liquid port 411, and the liquid for treating the waste liquid enters the flow channel 45 through the third liquid port 411. At this time, the flow channel 45 is in the space formed by the outer shell 41, the inner sleeve 42 and the sealing ring 44. Moreover, since the sealing ring 44 is in close contact with the outer shell 41 and the inner sleeve 42, the flow channel 45 forms a closed space, and the liquid can only enter and exit through the first liquid port 422 or the third liquid port 411, so the airtightness of the spray assembly 40 is guaranteed. Since a plurality of spray positions 421 are provided on the inner sleeve 42, a plurality of first liquid ports 422 exist on the inner sleeve 42, and each first liquid port 422 is connected to the flow channel 45. The flow channel 45 formed by this solution can be connected to a plurality of first liquid ports 422, so there is no need to open a separate channel corresponding to the plurality of first liquid ports 422, thereby reducing the difficulty of design and saving production costs.

[0043] See Figure 7 and Fig. 9 As shown, a mounting platform is provided outside the housing 41, wherein the third liquid port 411 is opened in the middle of the mounting platform, and the liquid inlet pipe 20 and the mounting platform are matched by threads to complete the connection between the liquid inlet pipe 20 and the spray assembly 40. In this embodiment, the liquid inlet pipe 20 is directly used for liquid inlet, and in other embodiments, another flexible pipe can be used to pass through the liquid inlet pipe 20 and then match with the third liquid port 411.

[0044] See Figure 7 and Fig. 9 As shown, when the inner sleeve 42 and the sealing ring 44 are installed in the installation space of the outer shell 41, one end of the inner sleeve 42 protrudes from the installation space. When the end cover 43 is installed, the end cover 43 is pressed on the inner sleeve 42 through the close fit between the end cover 43 and the outer shell 41, thereby applying a pressure to the inner sleeve 42, so that the inner sleeve 42 and the sealing ring 44 are squeezed, thereby ensuring the airtightness of the flow channel 45.

[0045] When the sealing ring 44 is installed, it is placed along the edge of the installation space of the housing 41, 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 specifically rectangular in this embodiment.

[0046] See Figures 7 to 10 As shown, the end cover 43 is provided with a plurality of avoidance holes 431 corresponding to the spray position 421, and a positioning column 432 protruding toward the inner sleeve 42 is provided, and the inner sleeve 42 is provided with a groove 423 matching the positioning column 432; the positioning column 432 cooperates with the groove 423 to limit the spray position 421 to correspond to the avoidance hole 431, and the inner diameter of the avoidance hole 431 is smaller than the outer diameter of the spray block 46 to limit the spray block 46 in the spray position 421. The avoidance hole 431 can not hinder the discharge of liquid from the first liquid port 422, and can also allow the gas in the reactor 10 to act on the spray block 46. The inner diameter of the avoidance hole 431 is smaller than the outer diameter of the spray block 46, so the spray block 46 is blocked when encountering the side edge of the avoidance hole 431 during the outward sliding action, which plays a limiting role. In addition, since the spray position 421 on the inner set 42 corresponds to a spray block 46, it is also necessary to ensure that each spray position 421 corresponds to at least one avoidance hole 431, so a positioning column 432 is provided on the end cover 43, and a groove 423 is provided on the inner set 42. Through the limiting effect of the positioning column 432 and the groove 423, it is ensured that each spray position 421 corresponds to at least one avoidance hole 431. There are two positioning columns 432 in this solution, and two corresponding grooves 423 are also provided. In other embodiments, one positioning column 432 can be used, but when one positioning column 432 is used, it cannot be set 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 disposed on the inner sleeve 42, and the groove 423 is disposed on the end cover 43; or the inner sleeve 42 can be provided with both the positioning column 432 and the groove 423, and the end cover 43 is correspondingly provided with the groove 423 and the positioning column 432.

[0048] See Figure 7 and Fig. 9 As shown, by providing an internal thread on the end cap 43 and an external thread on the outer side of the shell 41, the end cap 43 and the shell 41 are matched by threads, so the pressing force of the inner sleeve 42 can be determined by the degree of screwing. In other embodiments, the end cap 43 and the shell 41 can be connected by a buckle.

[0049] See Fig.10 and Fig.11As shown, the end of the spray block 46 facing the bottom of the spray position 421 is the inner end 462, and the end facing away from the spray position 421 is the outer end 463; the second liquid port 461 expands from the outer end 463 to the inner end 462, and the outer end 463 opens a ring-shaped recessed position 464 along the second liquid port 461, so that the recessed position 464 is pressurized and closed on one side of the second liquid port 461 located at the outer end 463 by air pressure. Through the position of the recessed position 464, when high pressure is generated in the reactor 10, the second liquid port 461 can be closed to prevent high-pressure gas from passing through the first liquid port 422, so as to play a second layer of protection. The side of the recessed position is used for force. Due to the inclined setting, the outer circle of force when under pressure is directed to the second liquid port 461, so as to play a role in closing the second liquid port 461. The second liquid port 461 is expanded at the inner end 462, which can ensure that when the liquid is discharged, multiple liquids are gathered and the pressurization effect can also be achieved. At this time, although the inner end 462 of the second liquid port 461 is enlarged, it is also misaligned with the first liquid port 422 .

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

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

[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 thus help improve the overall stability of the system.

[0053] See Figure 3 and Figure 6As shown, the sealing assembly 30 includes 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 the inner side abuts against the liquid inlet pipe 20, and the outer side abuts against the wall of the through hole 311, and the rubber pad 32 is sleeved on the liquid inlet pipe 20 and 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, and 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 reactor 10 is blocked when encountering the sealing ring 33, so it cannot leak out through the spray port 11. Moreover, the installation of the rubber pad 32 ensures that external dust and objects cannot easily enter the through hole 311 , thereby preventing the sealing ring 33 from leaking due to dust and effectively slowing down the aging of the sealing ring 33 .

[0054] In addition, see Figure 6 As shown, the through hole 311 in the base 31 is also provided with a protruding blocking platform 312, and the sealing ring 33 is installed below the blocking platform 312. Therefore, when the sealing ring 33 is affected by air pressure, if it moves, it will also be blocked by the blocking platform 312 and finally stuck in a fixed position.

[0055] In this embodiment, the blocking platform 312 is arranged around the inner wall of the through hole 311, which can ensure that the pressure at each point is balanced when contacting the sealing ring 33, so the sealing ring 33 is less likely to deform, avoiding deformation that causes a gap at the contact position with the through hole 311 and thus air leakage. In other embodiments, multiple blocking platforms 312 can also be used, which are arranged at intervals on the inner wall of the through hole 311, which can also achieve a better blocking effect.

[0056] See Figure 6 As shown, the sealing ring 33 is provided with a conical annular groove 331 on one side facing the spray port 11, and the opening size of the conical annular groove 331 is larger than the bottom size. Under the action of air pressure, the two side walls of the conical annular groove 331 are forced to expand outward, so that the extrusion force between the sealing ring 33 and the through hole 311, and the sealing ring 33 and the liquid inlet pipe 20 is increased. This arrangement forms two inclined wall portions on both sides of the conical annular groove 331. When air pressure is applied to the inclined wall portions, the two inclined wall portions move outward, that is, move toward the side of the liquid inlet pipe 20 and the side of the inner wall of the through hole 311 of the base 31, and are pressed therewith. Therefore, when the air pressure is increased during sealing, the extrusion force increases, and the sealing effect is better, thereby cleverly overcoming the problem that the sealing ring 33 is easily invalid due to excessive pressure.

[0057] In this embodiment, a conical annular groove 331 structure is adopted. In other embodiments, other opening forms, such as rectangular or elliptical, may also be adopted.

[0058] In this embodiment, see Figure 6 As shown, a rubber pad 35 is provided between the base 31 and the spray port 11 to prevent air leakage from the gap generated when the base 31 and the spray port 11 are matched.

[0059] See Figures 3 to 6 As shown, 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 toward the side wall of the reactor 10; the upper end of the sealing assembly 30 is installed with a rotating drive assembly 50, and 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 a corner 23, the position facing the spray assembly 40 during spraying is not toward the bottom of the reactor 10, but located at the side wall of the reactor 10. Therefore, when the pressure of the liquid entering the liquid inlet pipe 20 is relatively low, the initial velocity of the liquid finally coming out of the second liquid port 461 is relatively low, that is, after coming out of the second liquid port 461, it begins to fall downward under the influence of gravity, such as liquid for treating waste liquid. If the pressure of the liquid entering from the liquid inlet pipe 20 is relatively high, the initial velocity of the liquid finally coming out of the second liquid port 461 is relatively high, and the second liquid port 461 expands from the outer end 463 to the inner end 462, which plays a role of boosting, so it can be directly sprayed onto the side wall of the reactor 10, and the effect of flushing the reactor 10 can be achieved at this time.

[0061] See Figure 4 and Figure 5 As shown, the liquid inlet pipe 20 is driven to rotate by the transmission drive assembly, so the spray assembly 40 can also rotate. Therefore, under the action of high-pressure liquid and the drive of the transmission drive assembly, the liquid sprayed by the spray assembly 40 can surround the side wall of the reactor 10 for flushing. At this time, the liquid can be clean water, cleaning liquid, etc.

[0062] Specifically 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. At this angle, the liquid can be guaranteed to have a downward angle and an initial velocity in the horizontal direction, so that the 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, and the angle between the bent part and the horizontal plane is 60 degrees.

[0063] See Figure 7As shown, in this embodiment, the liquid inlet pipe 20 is a whole and then bent. In other embodiments, the liquid inlet pipe 20 can be multi-sectioned, such as a straight pipe plus a curved pipe portion to form a liquid inlet pipe 20.

[0064] See Figure 6 As shown, specifically, a first bearing 34 is installed in the through hole 311. 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 platform 312 and is stuck in this position. Since the liquid inlet pipe 20 needs to rotate, the first bearing 34 can play a role in limiting and facilitating rotation. Figure 6 As shown, the rubber pad 32 has a protruding structure, which is stuck in the through hole 311 and close to the upper surface of the first bearing 34. This setting can give the first bearing 34 an upper limit and 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 rotation drive assembly 50 includes a driving motor 51, a transmission group 52 and a transmission wheel 53, wherein the transmission wheel 53 is sleeved on the first section 21 of the liquid inlet pipe 20, and the driving 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 group structure, which drives the gear group to rotate through the output shaft of the driving motor 51, and then drives the transmission wheel 53 to rotate, 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 located on the outside, and the protective shell is installed with second bearings 54 on both upper and lower sides of the protective shell that cooperates with the liquid inlet pipe 20. Through the action of the second bearing 54, it is ensured that the rotation position of the gear group and the transmission wheel 53 is not easy to change, thereby ensuring the stability of the transmission. In addition, the protective shell is fixedly connected to the sealing assembly 30 to complete the installation and fixation.

[0067] A waste liquid treatment spraying method, using the waste liquid treatment spraying system, comprises the following steps:

[0068] Adding the waste liquid to be treated into the reactor 10;

[0069] Liquid for treating waste liquid is added through the liquid inlet pipe 20 and sprayed into the reactor 10 through the spray assembly 40;

[0070] When the addition of the liquid for treating the waste liquid is stopped, the waste liquid reacts to generate gas, and pushes the spray block 46 to move and block the first liquid port 422 .

[0071] The above embodiments are not exhaustive enumerations of the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
