Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a spraying system for treating industrial waste gas. Background Art

[0002] The spray system for industrial waste gas treatment sprays spray liquid through an atomizing nozzle to react with the rising gas for purification. In order to achieve a better atomization effect, a spiral nozzle is often used. The bottom of the spiral nozzle is a spiral flow channel with a radius that continuously decreases from top to bottom. The spiral nozzle is often installed by spiral installation and needs to be tightened or disassembled with a wrench.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention is provided with a connecting assembly. When installing the nozzle assembly, it is only necessary to drive the U-shaped frame downward by sliding the slip ring on the outer side of the installation tube, so that the end of the U-shaped frame pushes the block close to the installation tube through the guide slope, so that the outermost side of the plurality of blocks is smaller than the inner diameter of the fixed tube, and then the installation tube is inserted into the fixed tube and the slip ring is loosened. When the plurality of blocks move to one side of the slot, the elastic force of the first spring causes the plurality of blocks to slide into the slot, thereby completing the installation of the nozzle assembly; when disassembling the nozzle assembly, the slip ring is pulled down so that the end of the U-shaped frame pushes the block out of the slot through the guide slope, and then the installation tube moves downward to be disengaged, thereby completing the disassembly of the nozzle assembly. No tools are required, the operation is simple, the efficiency is high, and the nozzle assembly is convenient for maintenance and replacement.

[0018] (2) The present invention is provided with a fixed block and a movable block. When not in use or the water pressure is low, the third spring causes the inner wall of the conical tube to collide with the outer wall of the fixed block and the movable block, so that the conical tube is in a closed state, thereby preventing particles from entering the nozzle assembly or the spray pipe and causing blockage, thereby increasing the service life.

[0019] (3) As mentioned above, when the water pressure is large enough, the spray liquid pushes the slide tube and the conical tube to move downward, thereby making the conical tube and the fixed sealing block and the movable block, so that the spray liquid flows downward from the gap between the conical tube and the fixed sealing block and the movable block, and is atomized and sprayed out through the spiral flow channel at the bottom. In this way, the moving distance of the slide tube can be controlled according to the size of the water pressure, thereby adjusting the size of the gap between the conical tube and the fixed sealing block and the movable block, thereby realizing the adjustment of the flow rate of the spray liquid.

[0020] (4) The present invention is provided with a slide plate, a first connecting rod, a second connecting rod, a third connecting rod, a first guide groove and a second guide groove. When the fixed block and the movable block move into the range of the slide cylinder, the flow rate of the spray liquid is limited by the size of the passable area of ​​the spray liquid between the outermost sides of the fixed block and the movable block and the inner wall of the slide cylinder. When the water pressure continues to increase, the slide cylinder continues to move downward so that the top of the first slide groove drives one end of the first connecting rod to slide downward, so that the other end of the first connecting rod slides in the second slide groove and drives one end of the second connecting rod to move, thereby driving the slide plate and one end of the third connecting rod to rise through the other end, and then driving the movable block to rotate upward, so that the passable area of ​​the spray liquid is increased, thereby continuing to increase the spray flow rate, thereby increasing the flow adjustment range and increasing practicality.

[0021] (5) The present invention is provided with a filter assembly, which drives the eccentric rod to make a circular motion through the rotation of the turntable, thereby driving the filter frame to make a fan-shaped reciprocating motion through the slide groove, thereby realizing the vibration of the plate filter, so that the waste residue particles gradually roll along the surface of the plate filter into the arc frame, avoiding the accumulation of waste residue particles on the plate filter and causing blockage, thereby reducing the cleaning frequency and improving the exhaust gas treatment efficiency.

[0022] (6) The present invention is provided with a spiral conveying rod. After the waste slag particles roll to the arc frame, the spiral conveying rod is rotated to gradually transfer the waste slag to the collection box, and finally fall into the collection box for collection and unified treatment, thereby further reducing the frequency of shutdown for cleaning and improving the waste gas treatment efficiency. In addition, the truncated cone-shaped through holes in the guide frame can reduce the amount of spray liquid entering the collection box. At the same time, when the filter frame reciprocates in a fan-shaped manner, the arc frame is driven to reciprocate in the bottom box through the connecting plate, thereby realizing the vibration of the arc filter, thereby avoiding the stuck particles and throwing out the spray liquid on the waste slag for filtration, thereby reducing the waste of spray liquid.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 11 As shown, the present invention provides the following technical solutions:

[0037] A spray system for industrial waste gas treatment, comprising a bottom box 1 and a tank body 2 fixed above the bottom box 1, wherein the top of the bottom box 1 is communicated with the bottom of the tank body 2, a filter assembly is arranged in the bottom box 1 below the tank body 2, a spray pipe 4 is fixedly installed in the tank body 2, a plurality of branch pipes 8 are fixedly installed on both sides of the spray pipe 4, a plurality of fixed cylinders 22 are fixedly installed at the bottom of the plurality of branch pipes 8, a plurality of fixed cylinders 22 are provided in each of the plurality of fixed cylinders 22, a plurality of nozzle assemblies are installed in each of the plurality of slots 24, the nozzle assembly comprises a mounting cylinder 26, and a connection assembly is arranged outside the mounting cylinder 26;

[0038] The connecting assembly includes a slip ring 29 slidably sleeved on the outside of the mounting tube 26 and a plurality of blocks 23 arranged in a circumferential array, and the plurality of blocks 23 are all slidably matched with the slots 24, a first spring 27 is provided between the plurality of blocks 23 and the mounting tube 26, a guide slope 28 is provided in the middle of the plurality of blocks 23, a plurality of inverted U-shaped frames 25 are fixedly installed on the top of the slip ring 29, one end of the plurality of U-shaped frames 25 is in sliding contact with the plurality of guide slopes 28 corresponding one by one, and a second spring 30 is fixedly connected between the other end of the plurality of U-shaped frames 25 and the mounting tube 26.

[0039] Based on the above disclosed structure, when installing and removing the nozzle assembly:

[0040] When installing the nozzle assembly, first slide the slip ring 29 downward on the outside of the installation cylinder 26, so that the slip ring 29 drives the multiple U-shaped frames 25 to move downward, and the ends of the multiple U-shaped frames 25 push the corresponding guide slopes 28 respectively. At the same time, the other ends of the multiple U-shaped frames 25 and the installation cylinder 26 compress the second spring 30. The guide slope 28 makes the multiple blocks 23 slide toward the middle of the installation cylinder 26 until the outermost side of the multiple blocks 23 is smaller than the inner diameter of the fixed cylinder 22. At the same time, the blocks 23 and the installation cylinder 26 compress the first spring 27, and then the installation cylinder 26 is inserted into the fixed cylinder 22. In the fixed cylinder 22, after the multiple blocks 23 are inserted into the fixed cylinder 22, the sliding ring 29 is loosened, and the elastic force of the second spring 30 causes the U-shaped frame 25 and the sliding ring 29 to move upward and reset. Under the elastic force of the multiple first springs 27, the multiple blocks 23 are pressed against the inner wall of the fixed cylinder 22, and the installation cylinder 26 is continuously inserted into the fixed cylinder 22 until the multiple blocks 23 move to one side of the slot 24. At this time, the elastic force of the first spring 27 causes the block 23 to slide into the slot 24, thereby limiting the up and down movement of the installation cylinder 26, thereby completing the installation of the nozzle assembly, and the operation is simple;

[0041] When disassembling the nozzle assembly, the slip ring 29 is directly pulled down to move the multiple U-shaped frames 25 downward, and the bottoms of the multiple blocking blocks 23 are in conflict with the slots 24 and cannot move downward, so that the ends of the multiple U-shaped frames 25 respectively push the corresponding guide slopes 28 to move the multiple blocking blocks 23 toward the middle of the installation tube 26 until the multiple blocking blocks 23 are all out of the slots 24. At this time, continuing to pull down the slip ring 29 will cause the multiple U-shaped frames 25 to push the installation tube 26 downward through the multiple blocking blocks 23, so that the installation tube 26 slides out of the fixed tube 22, thereby completing the disassembly of the nozzle assembly; in summary, the installation and disassembly of the nozzle assembly do not require the aid of tools, the operation is simple, the efficiency is high, and it is convenient for maintenance and replacement.

[0042] In addition, regarding the treatment process of industrial waste gas, it is also preferred to provide an exhaust pipe 3 penetrating and fixed on the top of the tank body 2 and an air intake pipe 7 penetrating and fixed on one side of the tank body 2, a demisting filler 17 and a washing filler 16 are fixedly installed in the tank body 2, and the demisting filler 17 and the washing filler 16 are respectively located on the upper and lower sides of the spray pipe 4, the air intake pipe 7 is located below the washing filler 16, and a liquid pump 10 and a liquid infusion pipe are connected in sequence between the bottom of the bottom box 1 and the spray pipe 4;

[0043] The nozzle assembly further comprises a slide cylinder 31 disposed in the mounting cylinder 26 and a conical cylinder 32 fixed to the bottom of the slide cylinder 31 . A spiral flow channel with a radius that continuously decreases from top to bottom is fixed to the bottom of the conical cylinder 32 .

[0044] Based on this, the spray liquid is added and stored in the bottom box 1. After the nozzle assembly is installed, the liquid pump 10 is started to input the spray liquid into the spray pipe 4 through the liquid infusion pipe, and then it is divided into multiple branch pipes 8, and then it passes through the fixed cylinder 22, the installation cylinder 26, the sliding cylinder 31 and the conical cylinder 32 in sequence, and finally it is continuously sprayed in the form of mist along the spiral flow channel, and evenly sprayed onto the washing filler 16. The industrial waste gas enters the tank body 2 through the air inlet pipe 7, and gradually rises along the tank body 2 into the washing filler 16. The rising waste gas in 6 fully reacts and adsorbs with the descending spray liquid, and the purified waste gas continues to rise and passes through the demisting filler 17 for drying, and is finally discharged from the tank body 2 through the exhaust pipe 3. At the same time, the spray liquid adsorbs the waste residue particles carried in the waste gas and the waste residue particles generated by the reaction, and gradually passes through the washing filler 16 and falls onto the filter component. The filter component filters the waste residue particles, and the spray liquid passes through the filter component into the bottom box 1, thereby realizing the circulation of the spray liquid and preventing the waste residue particles from clogging the liquid pump 10.

[0045] As mentioned above, regarding the spraying of the spray liquid, it is preferred to have the following structure:

[0046] A groove 35 is provided on the inner side of the mounting tube 26, a fixing frame 34 is fixedly installed in the mounting tube 26, a fixing rod 45 is fixedly installed at the bottom of the fixing frame 34, a fixed block 33 is fixedly installed at the bottom of the fixing rod 45, two through grooves are symmetrically provided on both sides of the fixed block 33, movable blocks 43 are rotatably connected in the two through grooves, the outer walls of the fixed block 33 and the two movable block 43 are slidably matched with the inner wall of the conical tube 32, a protrusion 38 is provided on the outer side of the sliding tube 31, the protrusion 38 is slidably connected in the groove 35, and a third spring 36 is fixedly connected between the bottom of the protrusion 38 and the groove 35.

[0047] As can be seen from the above, at the beginning, the third spring 36 pushes the protrusion 38 so that the slide 31 drives the conical cylinder 32 upward to press against the outer walls of the fixed block 33 and the movable block 43. After the spray liquid enters the slide 31 and the conical cylinder 32, the water pressure is low and the conical cylinder 32 cannot be pushed to drive the slide 31 and the protrusion 38 to compress the third spring 36, so that the bottom of the conical cylinder 32 is in a closed state, so as to avoid particles from entering the nozzle assembly when not in use or when the water pressure is low, causing blockage, thereby increasing the service life;

[0048] When the water pressure is large enough, the spray liquid pushes the conical cylinder 32 downward, so that the conical cylinder 32 and the slide cylinder 31 drive the protrusion 38 downward, so that the protrusion compresses the third spring 36, so that the conical cylinder 32 is separated from the outer walls of the fixed block 33 and the movable block 43, so that the spray liquid is sprayed out, and has a large water pressure to form a better atomization effect, so that it can better cover the range inside the tank body 2 and achieve a better exhaust gas treatment effect.

[0049] In addition, regarding the flow control of the spray liquid, it is preferably provided with the following structure:

[0050] A sliding plate 44 is provided on the outer sliding sleeve of the fixed rod 45, and a third connecting rod 42 is rotatably connected between the two ends of the sliding plate 44 and the two movable blocking blocks 43;

[0051] A first guide groove 37 is fixedly installed on the inner side of the slide 31, a second guide groove 39 is fixedly installed on the bottom of the fixed frame 34, a second connecting rod 41 is rotatably connected to the slide plate 44, and a first connecting rod 40 is rotatably connected to one end of the second connecting rod 41, and both ends of the first connecting rod 40 are slidably fitted in the first guide groove 37 and the second guide groove 39 respectively.

[0052] As can be seen from the above, when the fixed block 33 and the movable block 43 are located inside the conical cylinder 32, the flow rate of the spray liquid is controlled by the gap size between the conical cylinder 32 and the outer walls of the fixed block 33 and the movable block 43. The water pressure of the spray liquid is mainly used to overcome the elastic force of the third spring 36. The greater the water pressure of the spray liquid, the greater the compression length of the third spring 36, which makes the downward movement distance of the conical cylinder 32 and the sliding cylinder 31 longer, thereby making the gap between the conical cylinder 32 and the outer walls of the fixed block 33 and the movable block 43 larger, and then making the flow rate of the spray liquid larger. In this way, the flow rate of the spray liquid can be adjusted according to the size of the water pressure to increase practicality. In this process, when the water pressure gradually increases, one end of the first connecting rod 40 in the first guide groove 37 moves from the bottom of the first guide groove 37 to the top of the first guide groove 37, and the slide plate 44 is always located at the bottom of the fixed rod 45 under the action of the water pressure, so that the movable block 43 and the fixed block 33 are relatively fixed through the third connecting rod 42;

[0053] When the fixed block 33 and the movable block 43 are located on the inner side of the slide cylinder 26, the flow rate of the spray liquid is controlled by the passable area between the slide cylinder 31 and the fixed block 33 and the movable block 43. The upper and lower diameters of the inner walls of the slide cylinder 26 are consistent. The water pressure continues to increase, causing the conical cylinder 32 and the slide cylinder 31 to continue to move downward, so that the top of the first guide groove 37 drives the end of the first connecting rod 40 to move downward, and the other end of the first connecting rod 40 slides in the second guide groove 39 and drives the end of the second connecting rod 41 to slide outward along the second guide groove 39, so that the other end of the second connecting rod 41 drives the slide plate 44 to move upward along the fixed rod 45, and then drives the movable block 43 to rotate in the through groove through the third connecting rod 42, so that the outermost side of the movable block 43 gradually approaches the middle, thereby increasing the passable area between the slide cylinder 31 and the fixed block 33 and the movable block 43, thereby further increasing the flow rate of the spray liquid, thereby increasing the flow control range of the spray liquid and increasing practicality.

[0054] In addition, regarding the filter assembly, it is preferably provided with the following structure:

[0055] The filter assembly includes a filter frame 15 rotatably connected to the bottom box 1 at one end and a plate filter 14 fixed in the filter frame 15. An arc frame 9 is rotatably connected in the bottom box 1, and a plurality of arc filters 11 are fixedly mounted on the arc frame 9. A connecting plate 13 is rotatably connected between one end of the arc frame 9 and the other end of the filter frame 15. The top of the arc frame 9 contacts the inner top surface of the bottom box 1.

[0056] A slide groove 19 is provided on one side of the filter frame 15 , and a turntable 20 is rotatably provided on one side of the bottom box 1 . An eccentric rod 21 is fixedly installed at an eccentric position of the turntable 20 , and the eccentric rod 21 is slidably fitted in the slide groove 19 .

[0057] As can be seen from the above, the drive turntable 20 rotates, driving the eccentric rod 21 to make a circular motion around the axis of the turntable 20, and the eccentric rod 21 drives the filter frame 15 to reciprocate up and down in the bottom box 1 through the slide slot 19, so that the filter frame 15 drives the plate filter 14 to make a fan-shaped reciprocating motion to achieve the vibration of the plate filter 14, and the spray liquid and the adsorbed waste particles fall from the bottom of the washing filler 16 to the plate filter 14, so that the spray liquid passes through the plate filter 14 and falls into the bottom box 1 to realize the spray liquid circulation, and the waste particles are separated in the plate filter 14. At the same time, when the filter frame 15 reciprocates in a fan shape, the end of the filter frame 15 drives the arc frame 9 to reciprocate in the bottom box 1 through the connecting plate 13, thereby driving the arc filter 11 to reciprocate, so that the spray liquid on the waste residue particles is thrown out by centrifugal action and falls into the bottom box 1 through the arc filter 11, reducing the waste of spray liquid.

[0058] In addition, a collecting box 6 is fixedly installed on one side of the bottom box 1, and a spiral conveying rod 12 is rotatably provided in the bottom box 1. The spiral conveying rod 12 is located in the arc frame 9, and one end of the spiral conveying rod 12 extends into the collecting box 6. A collecting box 5 is slidably connected to the collecting box 6 below the end of the spiral conveying rod 12; a guide frame 18 is fixedly installed in the collecting box 6, and the guide frame 18 is sleeved on the outer side of the spiral conveying rod 12. A truncated cone-shaped through hole is provided on the inner side of the guide frame 18, and the outer side of the spiral blade at the end of the spiral conveying rod 12 conflicts with the inner wall of the truncated cone-shaped through hole. Based on this, the spiral conveying rod 12 is driven to rotate so that the blades of the spiral conveying rod 12 gradually convey the waste particles in the arc frame 9 toward the collection box 6. The rotation of the above-mentioned arc frame 9 can prevent the waste particles from being stuck on the arc filter 11. When the waste particles are conveyed to the guide frame 18, the truncated cone-shaped through holes in the guide frame 18 have a movable slope, so that the residual spray liquid can flow back to the arc frame 9 along the slope of the truncated cone-shaped through holes to reduce the spray liquid from entering the collection box 6 and reducing the waste of spray liquid. The waste particles are finally conveyed to the outside of the guide frame 18 by the bolt conveying rod 12 and fall into the collection box 5 below for collection, which can further reduce the cleaning frequency and improve the exhaust gas treatment efficiency.

[0059] In addition, the spiral conveying rod 12 and the shaft of the turntable 20 can be connected by a belt drive, so that they can be driven by a driving motor, thereby reducing the manufacturing cost of the equipment.
