Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a filtration mechanism for a waste gas spray tower liquid collection tank. Background Technology
[0002] In the environmental protection field of industrial waste gas treatment and dust control, spray towers have become a commonly used piece of equipment for many enterprises due to their advantages such as simple structure, high treatment efficiency, and wide applicability. Whether it is the purification of acid and alkali waste gas in chemical enterprises or the desulfurization and dust removal in coal-fired power plants, spray towers can be seen operating busily.
[0003] The water mist sprayed in the spray tower encapsulates dust and other impurities in the exhaust gas and causes them to fall. The filtered water can be reused. Existing filtration methods mainly involve increasing the volume of the sedimentation tank so that the liquid that has adsorbed dust and other impurities can enter and settle for a longer period of time. The water pump then extracts the clear liquid from the top layer for reuse. This not only results in a large area to be cleaned in the sedimentation tank, increasing the difficulty of cleaning, but also leads to insufficient sedimentation and can easily cause blockages inside the pump. Utility Model Content
[0004] This utility model addresses the deficiencies in the prior art by providing a filtration mechanism for the liquid collection tank of a waste gas spray tower.
[0005] This utility model is achieved through the following technical solution:
[0006] A filtration mechanism for a waste gas spray tower's liquid collection tank includes a return water tank, a cover plate, a connecting plate, a water pump, a sedimentation mechanism, a guide block, a slot, a filter pad, a pressure strip, and a drain pipe. The cover plate is installed on the top of the return water tank, the connecting plate is fixedly mounted on the top of the cover plate, the water pump is installed on the upper surface of the cover plate, the sedimentation mechanism is located inside one end of the return water tank, the guide block is fixedly mounted on the inner side of the bottom of the return water tank, the slot is fixedly mounted inside the return water tank, the filter pad is engaged inside the slot, and the pressure strip is installed on... At the top of the slot, the drain pipe is located at the bottom of the return water tank. The sedimentation mechanism includes a sedimentation tank, a sealing plate, a water collection ring, a drain pipe, an inlet pipe, a fixed mounting plate, a connecting rod, and a buffer plate. The sealing plate is located at the bottom of the sedimentation tank. The water collection ring is fixedly located on the outer side of the top of the sedimentation tank. The drain pipe is fixedly located outside the water collection ring. The fixed mounting plate is connected to the top of the cover plate. The inlet pipe is fixed to one end of the fixed mounting plate. The connecting rod is fixedly located at the bottom of the inlet pipe. The buffer plate is fixed to the bottom of the connecting rod.
[0007] In a preferred embodiment of the present invention, the water inlet pipe is disposed in the middle of the sedimentation tank, and the buffer plate at the bottom of the water inlet pipe is disposed on the inner side of the bottom of the sedimentation tank.
[0008] After the water that has absorbed dust and other impurities enters the sedimentation tank through the inlet pipe, it is buffered by the buffer plate. The buffer plate reduces the flow rate and reduces the impact on the bottom sediment, thereby reducing the impurity content in the water.
[0009] In a preferred embodiment of this utility model, an overflow groove is provided on the top of the sedimentation tank, and the end of the drain pipe is 2-6 cm away from the bottom of the water collection ring;
[0010] After settling, the water slowly overflows from the overflow outlet into the water collection ring. The bottom of the water collection ring and the end of the drain pipe have a certain height difference, which facilitates secondary sedimentation.
[0011] In a preferred embodiment of this utility model, the flow guide block is sleeved on the outside of the sedimentation tank, and its top is inclined toward the filter pad;
[0012] The guide block reduces the space in the return water tank, allowing the filtered water level to rise faster. After being filtered by the filter pad, the water is then sucked into the water pump for reuse.
[0013] In a preferred embodiment of the present invention, the water pump suction end penetrates the connecting plate and extends to the bottom inner side of the return water tank, the filter pad is disposed between the sedimentation tank and the water pump suction end, and the drain pipe is located between the filter pad and the sedimentation mechanism.
[0014] The filter pad filters the settled water again, reducing the suspended solids content in the water entering the pump. The drain pipe facilitates the effective removal of impurities intercepted by the filter pad.
[0015] In a preferred embodiment of the present invention, a conical sediment collection cover is provided at the bottom of the sedimentation tank, and the bottom end of the sediment collection cover extends through and to the outer side of the bottom of the return water tank.
[0016] The beneficial effects of this utility model are:
[0017] The improved internal sedimentation mechanism of the waste gas spray tower's liquid collection tank allows sufficient sedimentation time for the returned water containing impurities, ensuring effective removal of suspended solids. The overflowing returned liquid is then filtered again through the filter pad, ensuring filtration efficiency and maintaining the water level after filtration. This facilitates pump extraction for reuse, reduces the risk of pump blockage, and makes sediment easier to clean. Attached Figure Description

[0023] like Figure 1-3 The waste gas spray tower liquid collection tank filtration mechanism shown includes a return water tank 1, a cover plate 2, a connecting plate 3, a water pump 4, a sedimentation mechanism 5, a guide block 6, a slot 7, a filter pad 8, a pressure strip 9, and a drain pipe 10. The cover plate 2 is installed on the top of the return water tank 1, the connecting plate 3 is fixedly installed on the top of the cover plate 2, the water pump 4 is installed on the upper surface of the cover plate 2, the sedimentation mechanism 5 is located inside one end of the return water tank 1, the guide block 6 is fixedly installed on the inner side of the bottom of the return water tank 1, the slot 7 is fixedly installed inside the return water tank 1, the filter pad 8 is snapped into the inner side of the slot 7, the pressure strip 9 is installed on the top of the slot 7, and the drain pipe 10... 0 is located at the bottom of the return water tank 1. The sedimentation mechanism 5 includes a sedimentation tank 51, a sealing plate 52, a water collecting ring 53, a drain pipe 54, an inlet pipe 55, a fixed mounting plate 56, a connecting rod 57, and a buffer plate 58. The sealing plate 52 is located at the bottom of the sedimentation tank 51. The water collecting ring 53 is fixedly located on the outer side of the top of the sedimentation tank 51. The drain pipe 54 is fixedly located outside the water collecting ring 53. The fixed mounting plate 56 is connected to the top of the cover plate 2. The inlet pipe 55 is fixed to one end of the fixed mounting plate 56. The connecting rod 57 is fixedly located at the bottom of the inlet pipe 55. The buffer plate 58 is fixed to the bottom of the connecting rod 57.
[0024] Specifically, the inlet pipe 55 is located in the middle of the sedimentation tank 51, the buffer plate 58 at the bottom of the inlet pipe 55 is located on the inner side of the bottom of the sedimentation tank 51, the top of the sedimentation tank 51 is provided with an overflow groove, the end of the drain pipe 54 is 2-6 cm away from the bottom of the water collection ring 53, the guide block 6 is sleeved on the outside of the sedimentation tank 51, and its top is inclined towards the filter pad 8. The suction end of the water pump 4 passes through the connecting plate 3 and extends to the inner side of the bottom of the return water tank 1. The filter pad 8 is located between the sedimentation tank 51 and the suction end of the water pump 4. The drain pipe 10 is located between the filter pad 8 and the sedimentation mechanism 5. The bottom of the sedimentation tank 51 is provided with a conical sediment collection cover, and the bottom end of the sediment collection cover passes through and extends to the outer side of the bottom of the return water tank 1.
[0025] In this embodiment, the spray device atomizes the inhaled water. The water mist adsorbs and encapsulates dust and other impurities in the exhaust gas, and then enters the sedimentation tank 51 through the water inlet pipe 55. The water is buffered by the buffer plate 58 fixed at the bottom of the water inlet pipe 55 by the connecting rod 57, which slows down the water flow. Due to gravity, the impurities will settle in the sedimentation tank 51 into the sediment collection hood at the bottom. The settled water flows out from the overflow groove at the top of the sedimentation tank 51 into the water collection ring 53. The bottom of the water collection ring 53 and the end of the drain pipe 54 have a certain height difference, so that some floating objects cannot be discharged from the drain pipe 54. The returned water flows into the return water tank 1 through the drain pipe 54. Through the guidance of the guide block 6 and the volume compression, the water level in the return water tank 1 will be relatively high, so that it can be better filtered by the filter pad 8. The water filtered by the filter pad 8 is sucked into the water pump 4 for reuse.
[0026] Furthermore, the cover plate 2 is installed on the top of the return water tank 1 by screws. The fixing plate 56, which is fixed to the outside of the water inlet pipe 55, is connected to the top of one end of the cover plate 2. The water pump 4 is installed to the cover plate 2 through the connecting plate 3. When disassembling, first disassemble the water pump 4 and its connecting plate 3, and then separate the fixing plate 56 from the cover plate 2. The cover plate 2 can then be pulled out, which makes it easy to disassemble the pressure strip 9 and maintain or replace the filter pad 8. When cleaning, simply remove the bottom sealing plate 52 of the sedimentation tank 51. The impurities in the sediment collection hood at the bottom of the sedimentation tank 51 can be quickly cleaned. The drain pipe 10 is set between the sedimentation mechanism 5 and the filter pad 8. The impurities blocked by the filter pad 8 can be discharged from the return water tank 1 through the drain pipe 10. Cleaning is simple and maintenance is convenient. It also effectively reduces the cleaning area, reduces the workload, and ensures the filtration and reuse effect of water.
