Description

Technical Field

[0001] The invention discloses the technical field of waste gas treatment, and in particular relates to a waste gas treatment device for water reducing agent production. Background Art

[0002] Water reducer is an admixture widely used in the construction process of concrete buildings. It reduces the amount of water used during mixing while ensuring that the fluidity index of the cement slurry remains unchanged. However, in the process of preparing water reducer, highly volatile waste gas will be generated. After these waste gases are released into the air, they will have an impact on the environment and human environment. Therefore, these waste gases need to be treated. The existing method is to treat these waste gases through a spray tower. However, during the treatment process, particulate impurities will be generated when the waste gas comes into contact with the treatment liquid and accumulate in the spray tower.

The liquid spraying device 19 is used to spray the processing liquid uniformly in a downward circumferential direction in the processing shell 11, so that the processing liquid is in uniform contact with the exhaust gas. A fixing frame 110 is fixed on the lower side of the processing shell 11, and a filter cloth 111 is installed on the upper part of the fixing frame 110. The filter cloth 111 is used to filter particulate impurities in the processing liquid in the processing shell 11.

The upper end of the connecting pipe 16 is fixedly connected to the fixing frame 110 and is connected to the liquid storage cavity. The fixing frame 110 is provided with a filtering anti-blocking mechanism located in the filter cloth 111. The filtering anti-blocking mechanism is used to prevent the filter cloth 111 from being blocked.

[0031] Please refer to Figure 2-Figure 5, read this paragraph, the filtering anti-blocking mechanism includes a first motor 21, the first motor 21 is installed on the mounting frame at the lower side of the processing shell 11, the output shaft of the first motor 21 is fixedly connected to a rotating shaft 22 rotatably connected to the slag discharge pipe 13 and the fixed frame 110, the middle part of the rotating shaft 22 is fixedly connected to a rotating ring 23 located in the fixed frame 110, the rotating ring 23 is fixedly connected to a circumferentially distributed extrusion block 24, the extrusion block 24 is set as a right-angled triangle block, and the hypotenuse of the extrusion block 24 is located in the rotation direction of the rotating ring 23, the fixed frame 110 is fixedly connected to a circumferentially distributed support rod 25, the support rod 25 is slidably connected to a sliding rod 26, the sliding rod 26 is fixedly connected to a pressure piece 27, the pressure piece 27 is connected to the adjacent support rod 25 with a spring, the pressure piece 27 is composed of a circular plate and a straight rod, the extrusion block 24 is fixedly connected to the circumferentially distributed support rod 25, The inclined surface at its inclined edge squeezes the straight rod on the pressure-bearing piece 27 it passes through, so that the pressure-bearing piece 27 drives the adjacent sliding rod 26 to move. The fixed frame 110 is fixedly connected with a circumferentially distributed support rod 28. The support rod 28 is slidingly connected with a sliding shell 29. The sliding shell 29 is slidingly connected to the adjacent sliding rod 26, and a spring is connected between the two. The spring between the sliding shell 29 and the adjacent sliding rod 26 is initially in a compressed state. The elastic coefficient of the spring between the pressure-bearing piece 27 and the adjacent support rod 1 25 is greater than the elastic coefficient of the spring between the sliding shell 29 and the adjacent sliding rod 26. The swivel 1 23, the extrusion block 1 24, the support rod 1 25, the sliding rod 26, the pressure-bearing piece 27, the support rod 28 and the sliding shell 29 are all located in the liquid storage chamber. The support rod 1 25 is provided with an anti-blocking cleaning component for backwashing the filter cloth 111.

[0032] Please refer to Figure 4 and Figure 5 The second extrusion block 31 is fixed to the upper end of the adjacent sliding shell 29 and the adjacent support rod 25, and the second extrusion block 31 is connected to the adjacent sliding shell 29 by a tension spring.

[0033] When it is necessary to treat the waste gas generated during the production of water reducer (hereinafter referred to as waste gas), the operator first connects the air inlet pipe 12 with the pipeline for transporting the waste gas, and starts the circulation pump 15 and the liquid spraying device 19. The circulation pump 15 works to transport the treatment liquid in the liquid storage chamber through the connecting pipe 16, the connecting pipe 2 17 and the connecting pipe 3 18 to the liquid spraying device 19. The liquid spraying device 19 works to spray the treatment liquid therein downward evenly.

[0034] After the air intake pipe 12 is connected to the pipe for transporting exhaust gas, the exhaust gas enters the air intake pipe 12 and floats out evenly from one end of the air intake pipe 12 located in the bracket 1, and floats upward until the exhaust gas floating upward comes into contact with the treatment liquid. The treatment liquid purifies the exhaust gas and reacts with harmful substances in the exhaust gas to produce particulate impurities, which will fall with the unused treatment liquid.

[0035] During the above-mentioned process of treating exhaust gas, as the treatment liquid in the liquid storage chamber decreases, the newly fallen treatment liquid will enter the liquid storage chamber through the filter cloth 111. During this process, the filter cloth 111 filters the particulate impurities in the treatment liquid to prevent the particulate impurities in the treatment liquid from clogging in the connecting pipe or the circulation pump 15, thereby affecting the circulation of the treatment liquid.

[0036] When the operator starts the circulation pump 15 and the liquid spraying device 19, the operator starts the first motor 21 synchronously. The output shaft of the first motor 21 drives the rotating ring 1 23 to rotate through the rotating shaft 1 22. The rotating ring 1 23 drives the circumferentially distributed extrusion blocks 1 24 to rotate to squeeze the circumferentially distributed pressure-bearing parts 27. Taking the pressure-bearing part 27 located directly above the connecting pipe 1 16 as an example, after the pressure-bearing part 27 is squeezed by the extrusion block 1 24, the pressure-bearing part 27 drives the adjacent sliding rod 26 to move to the right. The pressure-bearing part 27 moves to the right to compress the adjacent spring. The sliding rod 26 drives the adjacent limiting plate 32 to move to the right. The limiting plate 32 drives the adjacent sliding shell 29 to move to the right through the adjacent extrusion block 2 31. Until the extrusion block 2 31 contacts the adjacent extrusion block 33, under the extrusion action of the extrusion block 33, the extrusion block 2 31 moves downward and stretches the adjacent tension spring, until the extrusion block 2 31 moves downward to release the limit fit with the adjacent limit plate 32, under the action of the spring between the sliding shell 29 and the adjacent sliding rod 26, the sliding shell 29 quickly moves to the left to reset and push the treatment liquid in the liquid storage chamber, so that the treatment liquid in the liquid storage chamber impacts the filter cloth 111, causing the filter cloth 111 to vibrate, thereby shaking off the particulate impurities adsorbed on the outside of the filter cloth 111, preventing the particulate impurities from continuing to adhere to the outside of the filter cloth 111, affecting the treatment liquid from entering the liquid storage chamber, and further affecting the circulation of the treatment liquid.

[0037] In the process of the slide rod 26 driving the adjacent limit plate 32 to move to the right, under the action of the tension spring between the extrusion block 2 31 and the adjacent sliding shell 29, the extrusion block 2 31 moves upward and resets. At this time, the extrusion block 2 31 slides at the L-shaped plate on the adjacent limit plate 32 after being reset.

[0038] As the sliding shell 29 moves rapidly to the left, the slide bar 26 continues to move to the right. At this time, the volume of the left cavity in the sliding shell 29 increases, but under the pushing action of the sliding shell 29, only a small part of the treatment liquid enters the cavity on the left side of the sliding shell 29. Until the sliding shell 29 is reset, the slide bar 26 is still moving to the right. At this time, the treatment liquid in the liquid storage chamber begins to quickly enter the cavity on the left side of the sliding shell 29. Until the extrusion block 24 rotates to no longer contact the adjacent pressure piece 27, under the action of the spring between the pressure piece 27 and the adjacent support rod 25, the pressure piece 27 drives the slide bar 26 to move rapidly to the left and reset, and quickly pushes the treatment liquid in the adjacent sliding shell 29. At this time, since the elastic coefficient of the spring between the pressure piece 27 and the adjacent support rod 25 is greater than that of the sliding shell Due to the elastic coefficient of the spring between 29 and the adjacent sliding rod 26, the speed at which the sliding rod 26 moves to the left and resets is greater than the speed at which the sliding shell 29 moves to the left and resets. At the same time, under the action of the sliding shell 29 guiding the treatment liquid inside it, the treatment liquid will concentrate to form a water column and quickly spray out from the left side of the adjacent sliding shell 29, impacting the filter cloth 111, causing the filter cloth 111 to vibrate further (at this time, the vibration amplitude of the filter cloth 111 is greater than the vibration amplitude when the sliding shell 29 is reset), thereby shaking off the particulate impurities adsorbed on the outside of the filter cloth 111. At the same time, the water column quickly sprayed out from the left side of the adjacent sliding shell 29 will also backwash the filter cloth 111, thereby flushing down the particulate impurities adsorbed on the outside of the filter cloth 111, further enhancing the cleaning effect of the particulate impurities adsorbed on the outside of the filter cloth 111.

[0039] When the second extrusion block 24 in the clockwise direction squeezes the adjacent pressure piece 27, the above process is repeated.

[0040] After the waste gas (hereinafter referred to as waste gas) generated when the water reducing agent is produced is treated, the operator disconnects the air intake pipe 12 from the waste gas transport pipe and shuts down the circulation pump 15, the liquid spraying device 19 and the first motor 21.

[0041] Example 2: Please refer to Figure 6 and Figure 7 , reading this paragraph, it also includes a slag discharge mechanism, which is used to discharge particulate impurities in the processing shell 11. The slag discharge mechanism is arranged on the slag discharge pipe 13. The slag discharge mechanism includes a floating block 41, which is slidably connected to the upper part of the rotating shaft 22. A connecting rod 42 is fixed to the lower side of the floating block 41. The connecting rod 42 is slidably connected to the fixing frame 110. A slide 43 is fixed to the lower end of the connecting rod 42. The slide 43 is sealed and slidably connected to the slag discharge pipe 13. A tension spring is connected between the slide 43 and the slag discharge pipe 13.

[0042] Please refer to Figure 6 and Figure 7 , read this paragraph, the air inlet pipe 12 is provided with a slag stabilizing assembly for stabilizing the position of the floating block 41, the slag stabilizing assembly includes a fixed block 51, the fixed block 51 is fixed to the upper side of the floating block 41, the fixed block 51 is slidably connected to the rotating shaft 22, the air inlet pipe 12 is located at the lower side of the processing shell 11 and is fixed with a connecting shell 52, the connecting shell 52 is rotatably connected to the rotating shaft 22, and a limiting block 53 is slidably connected in the connecting shell 52, a spring is connected between the limiting block 53 and the connecting shell 52, the floating block 41, the connecting rod 42, the slide 43 and the fixed block The sum of the gravity of 51 is less than the elastic force of the spring between the limit block 53 and the connecting shell 52, but the elastic coefficient of the tension spring between the slide 143 and the slag discharge pipe 13 is greater than the elastic coefficient of the spring between the limit block 53 and the connecting shell 52. A limit groove is provided on the front side of the fixed block 51. When the rear part of the limit block 53 is inserted into the limit groove on the fixed block 51, the fixed block 51 is limited by the limit block 53. The upper and lower sides of the rear part of the limit block 53 are both set as inclined surfaces, and the upper inclined surface is a friction surface, which is used to slow down the downward movement of the fixed block 51.

[0043] Please refer to Figure 6 and Figure 8 , read this paragraph, the bracket 1 is provided with a slag discharge auxiliary component for assisting the slag discharge pipe 13 to discharge particulate impurities in the processing shell 11, and the slag discharge auxiliary component includes an electric push rod 61, the electric push rod 61 is installed on the left side of the bracket 1, and a connecting tube 62 is embedded in the left side of the lower part of the processing shell 11. The telescopic end of the electric push rod 61 is slidably connected to the connecting tube 62, and the telescopic end of the electric push rod 61 is fixedly connected to a slide plate 2 63 located in the connecting tube 62, and the slide plate 2 63 is sealed and slidably connected to the connecting tube 62.

[0044] During the process of treating the waste gas, as the amount of treated waste gas increases, more and more particulate impurities accumulate on the lower side of the treatment shell 11, and the liquid level of the treatment liquid in the lower part of the treatment shell 11 is also gradually rising. At this time, as the liquid level of the treatment liquid in the treatment shell 11 rises, the float 41 moves upward under the buoyancy of the treatment liquid, and the float 41 drives the slide 43 to move upward through the connecting rod 42. The upward movement of the slide 43 pushes the particulate impurities on its upper side to move together and stretch the adjacent tension spring.

[0045] As the floating block 41 moves upward, the floating block 41 drives the fixed block 51 to move upward until the fixed block 51 moves to contact the limit block 53. Under the squeezing action of the upper side of the fixed block 51, the limit block 53 moves forward and compresses the adjacent spring until the upper edge of the rear side of the limit block 53 is lower than the upper edge of the upper limit groove of the fixed block 51. At this time, under the action of the spring between the connecting shell 52 and the limit block 53, the limit block 53 moves backward and resets, and squeezes the limit groove of the fixed block 51 through the inclined surface of its rear upper side, and at the same time cooperates with the buoyancy of the lower processing liquid in the processing shell 11 to make The fixed block 51 moves upward, and the fixed block 51 drives the slide plate 43 to move upward through the connecting rod 142 until the upper edge of the inclined surface on the rear side of the limit block 53 contacts the upper edge of the upper limit groove of the fixed block 51, and the limit block 53 no longer moves backward to reset. At the same time, the slide plate 43 moves to separate from the slag discharge pipe 13, so the particulate impurities in the processing shell 11 will follow the processing liquid into the slag discharge pipe 13 and be discharged from the slag discharge pipe 13, thereby preventing excessive accumulation of particulate impurities in the processing shell 11, causing the filter cloth 111 to be wrapped by the particulate impurities, causing the speed of the processing liquid entering the liquid storage chamber to slow down.

[0046] When the slide plate 43 moves to separate from the slag discharge pipe 13, the operator disconnects the air intake pipe 12 from the transport waste gas pipeline and shuts down the circulation pump 15, the liquid spraying device 19 and the first motor 21.

[0047] When discharging the particulate impurities accumulated in the processing shell 11, as the particulate impurities in the processing shell 11 decrease, the height of the processing liquid in the processing shell 11 continues to decrease. At this time, under the action of the tension spring between the slide plate 43 and the slag discharge pipe 13, the fixed block 51 moves downward and squeezes the inclined surface on the upper rear side of the limit block 53 through its upper limit groove, causing the limit block 53 to move forward and compress the adjacent spring. However, since the inclined surface on the upper rear side of the limit block 53 is a friction surface, the limit block 53 will not move forward quickly and move out of the limit groove on the fixed block 51. Therefore, the slag discharge pipe 13 has sufficient time to discharge the particulate impurities accumulated in the processing shell 11. Until the limit block 53 moves out of the limit groove on the fixed block 51, under the action of the tension spring between the slide plate 43 and the slag discharge pipe 13, the fixed block 51, the floating block 41, the connecting rod 142 and the slide plate 43 begin to move downward quickly to reset.

[0048] During the resetting process, when the slide plate 43 enters the slag discharge pipe 13, the slag discharge pipe 13 no longer discharges particulate impurities and processing liquid outward. At the same time, during the resetting process, when the fixed block 51 no longer squeezes the limit block 53, the limit block 53 moves backward and resets under the action of the spring between the limit block 53 and the connecting shell 52.

[0049] After the slide 43 enters the slag discharge pipe 13, the operator reconnects the air inlet pipe 12 with the transport waste gas pipeline, and starts the circulation pump 15, the liquid spraying device 19 and the first motor 21, thereby repeating the above process to treat the waste gas.

[0050] When discharging the particulate impurities accumulated in the processing shell 11, the operator turns on the electric push rod 61, and the telescopic end of the electric push rod 61 drives the slide plate 2 63 to move back and forth left and right in the connecting tube 62 to extract and discharge the processing liquid. When discharging the processing liquid into the processing shell 11, the discharged processing liquid impacts the particulate impurities accumulated at the bottom of the processing shell 11, thereby accelerating the speed of discharging the particulate impurities accumulated in the processing shell 11.

[0051] Example 3: Based on Example 2, please refer to Figure 9 , read this paragraph, it also includes a dosing mechanism, the dosing mechanism is arranged on the processing shell 11, the dosing mechanism is used to replenish the consumed processing liquid, the dosing mechanism includes a reflux tank 71, the reflux tank 71 is fixedly connected to the rear part of the left side of the processing shell 11, the left side of the processing shell 11 is fixedly connected with a dosing tank 72 and a mixing tank 73, the reflux tank 71 and the dosing tank 72 are both connected to the mixing tank 73, the connecting pipe 2 17 is connected to the reflux tank 71, the connecting pipe 3 18 is connected to the mixing tank 73, the dosing tank 72 is connected to the dosing pipe, and a dosing mixing component for mixing the processing liquid in the mixing tank 73 is provided on the processing shell 11.

[0052] Please refer to Figure 10 , read this paragraph, the dosing mixing assembly includes a second motor 81, the second motor 81 is installed on the left side of the processing shell 11, and a rotating shaft 82 is rotatably connected to the output shaft of the second motor 81 through a gear set in the mixing tank 73. The upper part of the rotating shaft 82 is provided with evenly distributed flow holes, and the diameter of the flow holes on the side close to the axis of the rotating shaft 82 is smaller than the diameter on the other side. The part of the rotating shaft 82 located in the mixing tank 73 is fixed with a stirring fan 83, and the internal thread of the rotating shaft 82 is connected to a reciprocating screw 84 that is slidably connected to the mixing tank 73. The diameter of the upper end of the reciprocating screw 84 is consistent with the inner diameter of the rotating shaft 82.

[0053] Before the circulation pump 15 works, when the operator connects the air intake pipe 12 with the pipe for transporting waste gas, the operator simultaneously connects the drug delivery pipe with the dosing tank 72. Then, during the operation of the circulation pump 15, the circulation pump 15 transports the treatment liquid into the reflux tank 71 through the connecting pipe 2 17, and then the treatment liquid in the reflux tank 71 enters the mixing tank 73. During this process, the treatment liquid that enters the dosing tank 72 through the drug delivery pipe enters the mixing tank 73, thereby replenishing the treatment liquid to prevent the harmful substances in the waste gas from not being treated cleanly due to insufficient treatment liquid sprayed by the spray device 19.

[0054] When the operator starts the circulation pump 15, the operator starts the second motor 81 synchronously. The output shaft of the second motor 81 drives the second shaft 82 to rotate through the gear set. The second shaft 82 drives the stirring fan 83 to rotate and stir the treatment liquid in the mixing tank 73, so that the refluxed and re-added treatment liquid are evenly mixed. At the same time, during the rotation of the second shaft 82, the second shaft 82 rotates the reciprocating screw 84 to move back and forth up and down. When the reciprocating screw 84 moves downward, the volume of the upper cavity in the second shaft 82 increases, and the treatment liquid passes through the flow above the second shaft 82. The reciprocating screw 84 enters into it, and when the reciprocating screw 84 moves upward, the reciprocating screw 84 squeezes the treatment liquid in the rotating shaft 82. At this time, since the diameter of the inner side of the flow hole on the rotating shaft 82 is smaller than the diameter of the outer side, although the reciprocating screw 84 moves back and forth at the same speed, the speed of the treatment liquid passing through the flow hole when it moves downward is lower than the speed when it moves upward. Therefore, the treatment liquid is ejected from the flow hole on the upper part of the rotating shaft 82 in a jet manner, thereby further accelerating the mixing speed of the reflux and re-added treatment liquid in the mixing tank 73.
