Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and particularly relates to a deodorizing and dust removing tower and an operating method thereof. Background Art

[0002] Deodorizing and dust removal tower is an environmental protection equipment that integrates deodorizing and dust removal functions. It is widely used in industrial waste gas treatment, sewage treatment, garbage treatment and other fields. The following is a detailed introduction to deodorizing and dust removal towers: 1. Definition and function: Deodorizing and dust removal towers effectively remove particulate matter, harmful gases and odors in waste gas through physical, chemical or biological methods to achieve waste gas purification. Its main functions include dust removal, deodorization, desulfurization, denitrification, removal of volatile organic compounds (VOCs), etc. 2. Working principle The working principle of deodorizing and dust removal towers depends on the specific type There are some differences, but generally include the following steps: Waste gas collection: introduce the waste gas to be treated into the deodorization and dust removal tower through a pipe; Pretreatment: Some systems may include pretreatment units, such as cooling, dust removal, etc., to reduce the burden on subsequent treatment units; Deodorization and dust removal: In the tower, the waste gas comes into contact with the spray liquid (such as clean water, chemical solution, etc.) or the filler layer (such as biological filler) to remove pollutants in the waste gas through adsorption, absorption, chemical reaction or biodegradation; Purified gas emission: The treated purified gas is discharged through the top of the tower to meet the emission standards.

[0003] At present, the existing deodorizing and dust removing tower allows the waste gas to enter the deodorizing and dust removing tower through a collection system under the power generated by a fan. The water tank at the bottom of the tower is equipped with liquid medicine (mixed according to the on-site waste gas conditions). The liquid medicine is lifted from the bottom of the tower to the spraying area by a water pump. Under the action of the liquid medicine and the water curtain, the liquid medicine fully contacts and reacts with the waste gas, and the large particles and impurities in the waste gas are washed in the circulating water. While the waste gas is adsorbed and decomposed, most of the dust is removed. Although this method can remove most of the dust in the waste gas, the treatment efficiency is low. At the same time, a small part of the dust in the waste gas that has not been removed will be discharged into the environment along with the treated waste gas, causing pollution to the environment. Based on this, a deodorizing and dust removing tower and an operating method thereof are proposed. Summary of the invention

[0027] The beneficial effects of the present invention are:

[0028] 1. The present invention uses a deflection mechanism and a cleaning mechanism in coordination. The deflection mechanism lengthens the flow distance of water mist and gas, and the water mist and gas fit in the deflection ring of the deflection mechanism, so that the particulate matter in the gas is absorbed by the water mist. The operation of the cleaning mechanism further slows down the flow speed of the water mist and gas in the deflection mechanism, so that the particulate matter in the gas is further absorbed by the water mist. At the same time, the cleaning mechanism can clean up the water droplets adhering to the inner wall of the deflection mechanism, which on the one hand increases the amount of water mist adsorbed in the deflection mechanism, and on the other hand reduces the flow speed of water mist and gas, thereby increasing the absorption amount and absorption efficiency of the particulate matter in the gas, thereby improving the treatment efficiency of the particulate matter in the gas.

[0029] 2. The present invention, through the arrangement of the defogger mechanism, on the one hand greatly increases the contact area and time of the exhaust gas in the tower body with the water mist and the liquid medicine, and the water vapor condenses on the petals of the defogger ball to absorb the particulate matter in the exhaust gas, and the droplets are separated and fall along the defogger ball after condensing to a certain extent, and on the other hand, when the magnetic plate of the defogger mechanism is intermittently aligned with the magnetic sheet, the defogger mechanism and the deflector mechanism will vibrate at the same time, and the droplets gathered on the defogger mechanism and the droplets gathered on the deflector mechanism will be shaken off, thereby further improving the treatment efficiency and treatment quality of the exhaust gas, and due to the vibration of the defogger mechanism and the deflector mechanism, the small droplets containing the particulate matter can be gathered to form large droplets under the action of vibration, thereby increasing the sedimentation rate, thereby improving the quality and efficiency of the separation treatment of the particulate matter in the exhaust gas.

[0030] 3. The present invention sets a rotating spray mechanism, and the spiral nozzle in the spray mechanism can fully atomize the mixed liquid into tiny droplets, forming a large contact area, fully contacting with the exhaust gas molecules, absorbing and decomposing organic and inorganic waste gases such as hydrogen sulfide and ammonia in the exhaust gas, so that the exhaust gas can be purified through adsorption and decomposition. In addition, due to the rotation of the spray mechanism, the contact area between the water mist and the exhaust gas can be expanded, and a certain stirring function can be generated, which further promotes the decomposition of pollutants in the exhaust gas and the adsorption of particulate matter in the exhaust gas by the water mist.

[0031] 4. The present invention uses a defogger mechanism and a scraper and suction mechanism in coordination, so that when the defogger mechanism vibrates, the scraper and suction mechanism can intermittently blow air toward the filter, so that when the scraper and suction mechanism scrapes away the particulate matter adhered to the water inlet side of the filter, the particulate matter adhered to the outer surface of the filter is separated from the filter by the action of the airflow and the scraping of the cleaning sleeve, and the impurities cleaned from the filter are prevented from accumulating around the cleaning sleeve, causing the cleaning sleeve to curl and be unable to fit the filter, thereby ensuring the cleaning function of the cleaning sleeve, thereby avoiding clogging of the filter, and preventing the clogging of the filter from causing the water pump to draw less water, resulting in insufficient pressure of the sprayed water mist, affecting the atomization quality of the water mist, thereby ensuring the treatment efficiency and quality of the water mist for exhaust gas.

The three support frames 9 and three grilles 10 are arranged in three groups, and each group has a support frame 9 and a grille 10, and the grille 10 is fixedly connected to the top of the support frame 9. The three groups of support frames 9 and grilles 10 can divide the exhaust gas into blocks when treating the exhaust gas, slow down the flow rate of the exhaust gas, so that the mixed liquid sprayed by the spray mechanism 12 can better contact with the exhaust gas, and at the same time, the outer surfaces of the support frames 9 and grilles 10 located below the spray mechanism 12 will also adhere to a certain amount of mixed liquid water mist, so that the exhaust gas can react with the mixed liquid water mist attached to the outer surfaces of the support frames 9 and grilles 10 when passing through the support frames 9 and grilles 10, further improving the treatment quality and The treatment efficiency also includes: a spray mechanism 12, the spray mechanism 12 is installed in the tower body 1, and is used to spray the mixed liquid into the exhaust gas.

By adopting the first spiral nozzle 1204 and the second spiral nozzle 1206, the mixed liquid can be fully atomized into tiny droplets. The droplets adhere to the filler to form a large contact area, which is fully in contact with the waste gas molecules, and absorbs and decomposes organic waste gases and inorganic waste gases such as hydrogen sulfide and ammonia in the waste gas, so that the waste gas can be purified through adsorption and decomposition.

[0047] When in use, close the drain valve at the bottom of the tower body 1, add water and liquid medicine into the water tank 5 through the water adding pipe and the medicine adding pipe of the water tank 5, mix to form a mixed liquid, then start the fan, the water pump 6 and the motor 1201, the fan transports the exhaust gas to the tower body 1 through the air inlet 2, the water pump 6 extracts the mixed liquid in the water tank 5 through the water pumping pipe 7, and injects the mixed liquid into the first spray ring 1203 and the second spray ring 1205 through the water injection pipe 8, spray water mist to the exhaust gas through the first spiral nozzle 1204 and the second spiral nozzle 1206, at the same time, the motor 1201 The rotation will drive the first spray ring 1203 and the second spray ring 1205 to rotate through the rotating shaft 1202, so that the first spiral nozzle 1204 and the second spiral nozzle 1206 rotate while spraying water mist, which can expand the contact area between the water mist and the exhaust gas, fully contact with the exhaust gas molecules, absorb and decompose organic and inorganic waste gases such as hydrogen sulfide and ammonia in the exhaust gas, so that the exhaust gas can be purified through adsorption and decomposition, and a certain stirring function is produced, which further promotes the decomposition of pollutants in the exhaust gas and the adsorption of particulate matter in the exhaust gas by water mist.

After the double deflection setting, the flow speed of the water mist and the exhaust gas in the deflection mechanism 11 is slowed down, so that the water mist can better separate the particulate matter in the exhaust gas from the exhaust gas, and the droplets formed by the separated particulate matter will adhere to the outer surface of the bottom deflector ring 1105 and the top deflector ring 1102, and settle downward along the outer surface of the bottom deflector ring 1105 and the top deflector ring 1102, slowing down the flow speed of the water mist and the exhaust gas, improving the separation efficiency of the particulate matter in the exhaust gas, and improving the absorption amount and absorption efficiency of the particulate matter in the exhaust gas by the water mist.

When the magnetic plate 1409 When the magnetic plate 1409 is separated from the alignment state with the top magnetic plate 1107 and the bottom magnetic plate 1108, the magnetic plate 1409 will impact the top baffle ring 1102 and the bottom baffle ring 1105 under the action of the reset spring 14010, so that the top baffle ring 1102 and the bottom baffle ring 1105 as well as the top demister ball 1406 and the bottom demister ball 1405 vibrate, which greatly increases the contact area and time of the exhaust gas in the tower body 1 with the water mist and the liquid medicine, and the water vapor condenses on the ball petals of the demister ball to absorb the particulate matter in the exhaust gas, and the droplets condense to a certain extent and flow along the demister ball. Separation and falling, on the other hand, when the magnetic plate 1409 of the defogger mechanism 14 is intermittently aligned with the magnetic sheet, the defogger mechanism 14 and the deflector mechanism 11 will vibrate at the same time, and the droplets accumulated on the defogger mechanism 14 and the droplets accumulated on the deflector mechanism 11 will be shaken off, thereby further improving the treatment efficiency and quality of the exhaust gas. In addition, due to the vibration of the defogger mechanism 14 and the deflector mechanism 11, the small droplets containing particulate matter can be aggregated to form large droplets under the action of vibration, thereby increasing the sedimentation rate, thereby improving the quality and efficiency of the separation treatment of particulate matter in the exhaust gas.

[0054] like Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the deodorizing and dust removing tower also includes: a scraping and suction mechanism 15, which is installed in the tower body 1, and a filter screen 16 is installed in the water tank 5. The scraping and suction mechanism 15 includes a swivel 1501 fixedly connected to the tower body 1, and a connecting hose 1502 is fixedly connected to the side wall of the swivel 1501. A one-way valve is installed in the connecting hose 1502, so that the gas in the swivel 1501 can only flow to the gas bin 1505 through the connecting hose 1502, and a cleaning plate 1504 is fixedly connected to the bottom of the connecting hose 1502. The cleaning plate 1504 is connected to the rotating shaft 1202 through threads, and the threaded connection part of the rotating shaft 1202 and the cleaning plate 1504 is set in the form of a reciprocating screw, and an air bin 1505 is opened in the cleaning plate 1504. A cleaning sleeve 1506 is fixedly connected to the end of the cleaning plate 1504 close to the filter screen 16. The sleeve 1506 is composed of multiple bristles. The cleaning sleeve 1506 is attached to the water inlet side of the filter 16. The swivel 1501 is sealed and rotatably connected to the rotating shaft 1202. The rotating shaft 1202 is located above the bottom of the swivel 1501 and is set to a hollow form. The side wall of the rotating shaft 1202 located in the swivel 1501 is provided with a through hole 1503. The bottom of the fixed frame 1301 is provided with multiple air inlet holes 17. The swivel 1501 is connected with the interior of the rotating shaft 1202 through the through hole 1503, the rotating shaft 1202 is connected with the interior of the fixed frame 1301, the connecting hose 1502 is connected with the interior of the air warehouse 1505, and the multiple air inlet holes 17 are connected with the interior of the fixed frame 1301. One-way valves are installed in the multiple air inlet holes 17, so that when the piston cylinder 1407 is evacuated, the fixed frame 1301 can only extract the air flow in the tower body 1 through the multiple air inlet holes 17.

[0055] When the rotating shaft 1202 rotates, the cleaning plate 1504 will move up and down under the action of the part of the rotating shaft 1202 set as a reciprocating screw, thereby driving the cleaning sleeve 1506 to clean up the impurities attached to the water inlet side of the filter 16. At the same time, when the magnetic plate 1409 rotates to face the top magnetic sheet 1107 and the bottom magnetic sheet 1108, the piston plate 1408 will move along the inner surface of the piston cylinder 1407 toward the fixed frame 1301, squeezing the gas in the piston cylinder 1407 into the fixed frame through the through hole 14011 1301, and then the gas in the fixing frame 1301 will be discharged into the rotating ring 1501 through the hollow rotating shaft 1202 through the through hole 1503, and then discharged into the gas chamber 1505 through the connecting hose 1502, and finally blown to the filter 16, so that when the cleaning sleeve 1506 scrapes the impurities on the water inlet side of the filter 16, the gas will blow the impurities on the filter 16 cleaned by the cleaning sleeve 1506 away from the filter 16, so as to prevent the impurities cleaned from the filter 16 from accumulating around the cleaning sleeve 1506, causing the cleaning sleeve 1506 to curl. The filter screen 16 cannot be attached, which ensures the cleaning function of the cleaning sleeve 1506, and the airflow can promote the uniformity of the mixed liquid when blowing towards the filter screen 16, thereby further improving the quality and efficiency of exhaust gas treatment. When the magnetic plate 1409 rotates away from the position of the top magnetic plate 1107 and the bottom magnetic plate 1108, the piston plate 1408 will move away from the fixing frame 1301 under the action of the return spring 14010, and the piston cylinder 1407 will extract the liquid in the fixing frame 1301 through the through hole 14011. Gas, at this time, the fixed frame 1301 will draw the gas in the tower body 1 into the fixed frame 1301 through multiple air inlet holes 17, and repeat this process, intermittently blowing air to the filter 16, so that the particulate impurities attached to the outer surface of the filter 16 are separated from the filter 16 by the scraping of the air flow and the cleaning sleeve 1506, thereby avoiding the blockage of the filter 16, preventing the blockage of the filter 16 from causing the water pump 6 to draw less water, resulting in insufficient pressure of the sprayed water mist, affecting the atomization quality of the water mist, thereby ensuring the treatment efficiency and quality of the water mist for the exhaust gas.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, a method for operating a deodorizing and dust removing tower comprises the following steps:

[0057] Step 1: add water to the water tank 5 through the water adding pipe, close the drain valve of the tower body 1, and add the corresponding biological deodorant or plant deodorant or chemical agent into the water tank 5 through the dosing pipe to mix and form a mixed liquid, close the drain valve at the bottom of the tower body 1, add water and liquid medicine into the water tank 5 through the water adding pipe and the dosing pipe of the water tank 5, and mix to form a mixed liquid;

[0058] Step 2: The air inlet 2 is connected to the fan for conveying the exhaust gas;

[0059] Step 3: Start the fan to transport the exhaust gas into the tower body 1 through the air inlet 2;

[0060] Step 4: Start the water pump 6 while starting the fan, so that the water pump 6 extracts the mixed liquid in the water tank 5 through the water pumping pipe 7, and injects the mixed liquid into the first spray ring 1203 and the second spray ring 1205 through the water injection pipe 8, and sprays water mist to the exhaust gas through the first spiral nozzle 1204 and the second spiral nozzle 1206, so as to deodorize and remove dust from the exhaust gas entering the tower body 1;

[0061] The water pump 6 extracts the mixed liquid in the water tank 5 through the water pumping pipe 7, and injects the mixed liquid into the first spray ring 1203 and the second spray ring 1205 through the water injection pipe 8, and sprays water mist to the exhaust gas through the first spiral nozzle 1204 and the second spiral nozzle 1206;

[0062] The waste gas after being sprayed by the first spiral nozzle 1204 and the second spiral nozzle 1206 will flow upward, first enter the bottom baffle ring 1105, and then flow out from the bottom baffle ring 1105 into the top baffle ring 1102. After the double baffle setting, the flow speed of the water mist and the waste gas in the baffle mechanism 11 is slowed down, so that the water mist can better separate the particulate matter in the waste gas from the waste gas, and the droplets formed by the separated particulate matter will adhere to the outer surfaces of the bottom baffle ring 1105 and the top baffle ring 1102, and settle downward along the outer surfaces of the bottom baffle ring 1105 and the top baffle ring 1102;

[0063] Step 5: When the water pump 6 is working, the motor 1201 is started, so that the first spray ring 1203 and the second spray ring 1205 rotate to spray water mist, and the cleaning mechanism 13 cleans the baffle mechanism 11, and the scraping mechanism 15 cleans the filter 16;

[0064] The motor 1201 drives the first spray ring 1203 and the second spray ring 1205 to rotate through the rotating shaft 1202, so that the first spiral nozzle 1204 and the second spiral nozzle 1206 rotate while spraying water mist, which can expand the contact area between the water mist and the exhaust gas, fully contact with the exhaust gas molecules, absorb and decompose organic and inorganic exhaust gases such as hydrogen sulfide and ammonia in the exhaust gas, so that the exhaust gas can be purified through adsorption and decomposition, and a certain stirring function is generated, which further promotes the decomposition of pollutants in the exhaust gas and the adsorption of particulate matter in the exhaust gas by water mist;

[0065] When the rotating shaft 1202 rotates, it will drive the fixed frame 1301 to rotate, and then drive the top cleaning spiral plate 1302 and the bottom cleaning spiral plate 1303 to rotate along the outer surface of the top baffle ring 1102 and the bottom baffle ring 1105, further slowing down the flow speed of water mist and gas in the top baffle ring 1102 and the bottom baffle ring 1105, so that the particulate matter in the gas is further absorbed by the water mist. At the same time, the top cleaning spiral plate 1302 and the bottom cleaning spiral plate 1303 can clean up the water droplets adhering to the outer surface of the top baffle ring 1102 and the bottom baffle ring 1105, on the one hand, increasing the amount of water mist adsorbed in the top baffle ring 1102 and the bottom baffle ring 1105, on the other hand, reducing the flow speed of water mist and gas, increasing the absorption amount and absorption efficiency of particulate matter in the gas, thereby improving the processing efficiency of particulate matter in the gas, and the cleaned droplets will fall to the bottom of the tower body 1, mix with the mixed liquid in the water tank 5, and filter the impurities in the mixed liquid under the action of the filter screen 16;

[0066] At the same time, the rotation of the fixing frame 1301 will drive the top demister ball 1406 and the bottom demister ball 1405 to revolve along with the fixing frame 1301, and at the same time, the worm 1403 will drive the gear 1402 to revolve. At this time, due to the setting of the gear ring 1401, the gear 1402 will rotate while revolving, thereby driving the worm 1403 to rotate while revolving. The worm 1403 will drive the top demister ball 1406 and the bottom demister ball 1405 to rotate while revolving through the worm gear 1404, which can stir the water mist and the exhaust gas, greatly The contact area and time of the exhaust gas in the tower body 1 with the water mist and the liquid medicine are increased, and the water vapor condenses on the ball petals of the demisting ball. After the droplets condense to a certain extent, they separate and fall along the demisting ball. It has the characteristics of small pressure drop, large specific surface area and high demisting efficiency. During the revolution of the top demisting ball 1406 and the bottom demisting ball 1405, the magnetic plate 1409 will intermittently align with the top magnetic sheet 1107 and the bottom magnetic sheet 1108. When the magnetic plate 1409 is aligned with the top magnetic sheet 1107 and the bottom magnetic sheet 1108, the reset spring 14010 will be stretched. When the magnetic plate 1409 is aligned with the top magnetic sheet 1107 and the bottom magnetic sheet 1108, the reset spring 14010 will be stretched. When the magnetic plate 1409 is separated from the alignment state with the top magnetic plate 1107 and the bottom magnetic plate 1108, the magnetic plate 1409 will hit the top baffle ring 1102 and the bottom baffle ring 1105 under the action of the reset spring 14010, so that the top baffle ring 1102 and the bottom baffle ring 1105 and the top demister ball 1406 and the bottom demister ball 1405 vibrate, which greatly increases the contact area and time of the exhaust gas in the tower body 1 with the water mist and the liquid medicine, and the water vapor condenses on the ball petals of the demister ball to absorb the particulate matter in the exhaust gas. After the droplets condense to a certain extent, they will move along the demister ball. The balls separate and fall. On the other hand, when the magnetic plate 1409 of the defogger 14 is intermittently aligned with the magnetic sheet, the defogger 14 and the baffle 11 will vibrate at the same time, and the droplets gathered on the defogger 14 and the baffle 11 will be shaken off, further improving the treatment efficiency and quality of the exhaust gas. In addition, due to the vibration of the defogger 14 and the baffle 11, the small droplets containing particulate matter can be aggregated to form large droplets under the action of vibration, thereby increasing the sedimentation rate, thereby improving the quality and efficiency of the separation treatment of particulate matter in the exhaust gas.

[0067] In this process, when the rotating shaft 1202 rotates, the cleaning plate 1504 will move up and down under the action of the part of the rotating shaft 1202 set as a reciprocating screw, thereby driving the cleaning sleeve 1506 to clean up the impurities attached to the water inlet side of the filter screen 16. At the same time, when the magnetic plate 1409 rotates to face the top magnetic sheet 1107 and the bottom magnetic sheet 1108, the piston plate 1408 will move along the inner surface of the piston cylinder 1407 toward the fixing frame 1301, squeezing the gas in the piston cylinder 1407 through the through hole 14011. The gas in the fixing frame 1301 is then discharged into the rotating ring 1501 through the hollow rotating shaft 1202 and the through hole 1503, and then discharged into the gas chamber 1505 through the connecting hose 1502, and finally blown to the filter screen 16, so that when the cleaning sleeve 1506 scrapes the impurities on the water inlet side of the filter screen 16, the gas blows the impurities on the filter screen 16 cleaned by the cleaning sleeve 1506 away from the filter screen 16, so as to prevent the impurities cleaned from the filter screen 16 from accumulating around the cleaning sleeve 1506, causing the cleaning sleeve 1506 to 06 curled and unable to fit the filter 16, ensuring the cleaning function of the cleaning sleeve 1506, and the airflow can promote the uniformity of the mixed liquid when blowing to the filter 16, thereby further improving the quality and efficiency of exhaust gas treatment, and when the magnetic plate 1409 rotates away from the position of the top magnetic sheet 1107 and the bottom magnetic sheet 1108, the piston plate 1408 will move away from the fixing frame 1301 under the action of the return spring 14010, and the piston cylinder 1407 will extract the fixing frame 1301 through the through hole 14011 At this time, the fixed frame 1301 will extract the gas in the tower body 1 through the multiple air inlet holes 17 and enter the fixed frame 1301, and so on, intermittently blowing air to the filter 16, so that the particulate impurities attached to the outer surface of the filter 16 are separated from the filter 16 under the action of the air flow and the scraping of the cleaning sleeve 1506, thereby avoiding the clogging of the filter 16, preventing the clogging of the filter 16 from causing the water pump 6 to extract less water, resulting in insufficient pressure of the sprayed water mist, affecting the atomization quality of the water mist, thereby ensuring the treatment efficiency and treatment quality of the water mist for the exhaust gas;

[0068] The treated waste gas is discharged to the outside through the air outlet 3;

[0069] Step 6: After the exhaust gas treatment is completed, turn off the fan, water pump 6 and motor 1201, and clean the tower body 1.

[0070] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
