Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental protection purification equipment technology, and relates to a waste gas purification device, and more particularly to an automatic flushing purification device. Background Technology
[0002] With the technological upgrades in the waste treatment industry, the importance of deodorization and purification systems is becoming increasingly prominent. For example, the deodorization devices disclosed in patents ZL202021337446.0 and ZL201920475230.1 both consist of a large, cylindrical, enclosed tower shell. The internal space of the tower shell is divided into multiple filtration layers vertically, including a packing deodorization layer, a filter cotton deodorization layer, a spray layer, and a demisting layer. Waste gas enters the tower shell from near the bottom and passes through each filtration layer sequentially from bottom to top, thus being purified before being discharged. These filtration layers primarily utilize the principles of physical adsorption, material adsorption, and chemical reactions to adsorb or neutralize toxic substances in the odorous gas, thereby achieving the purpose of waste gas purification and deodorization.
[0003] The aforementioned patent documents contain some defects, such as:
[0004] 1. Each filter layer contains only one type of filter material. Taking the packed deodorization layer as an example, activated carbon is typically used as the packing material. The area covered by the activated carbon layer is roughly the same as the radial dimension of the entire tower shell. When exhaust gas passes through, the activated carbon in the center ensures full contact with the exhaust gas flow, while the activated carbon on the periphery has poor contact because the airflow concentrates in the central area. This results in uneven adsorption of the activated carbon layer, excessive consumption of the activated carbon in the central area, directly leading to a reduction in the overall lifespan of the activated carbon layer. Long-term use will result in substandard exhaust gas purification. In particular, the overall height of the activated carbon layer only accounts for 1 / 10 of the total tower height. The activated carbon layer itself is relatively thin, allowing the exhaust gas flow to easily pass through. The exhaust gas flow passes through the activated carbon layer quickly, resulting in a less than ideal adsorption reaction and poor purification efficiency.
[0005] 2. The filter layers inside the tower are arranged vertically at intervals, which makes the tower taller and occupies a lot of vertical space in the installation site. At the very top of the tower, a demister must be integrated. The demister usually uses demister packing, such as Pall rings and multi-faceted hollow spheres. These demister packings need to be cleaned or replaced regularly after use to avoid the formation of biofilm that clogs the demister. This makes it very difficult to clean and replace the demister, which is located at a high position. Similarly, the demister also suffers from the above-mentioned problem of uneven demister removal, which is difficult to deal with. Utility Model Content
[0006] To address the shortcomings of existing technologies, this invention provides an automatic flushing and purification device. It solves the technical problem of poor purification effect in existing waste gas purification equipment.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An automatic flushing and purification device includes a tower shell with a chamber. The chamber is provided with at least two deodorizing inner liner arranged horizontally and connected in sequence. Each deodorizing inner liner is equipped with a demister at its outlet. The demister includes a demisting packing and a high-pressure spray assembly. The high-pressure spray assembly is arranged towards the demisting packing and a pressure detection element is provided at the demisting packing.
[0009] The tower shell of this purification equipment is equipped with multiple independent deodorizing inner tanks, which are connected to each other in sequence. Each deodorizing inner tank can perform the same and independent deodorization and purification operation. This is equivalent to allowing the odor to repeatedly pass through the deodorizing inner tank, and improving the adsorption efficiency step by step without increasing the total amount of consumables, thereby greatly improving the purification effect.
[0010] This purification equipment is equipped with an independent demister at the outlet of each deodorizing inner tank. The demister can remove the water vapor and aerosols carried in the odor, performing secondary purification of the odor and improving the purification effect. At the same time, the design of multiple demisters and multiple deodorizing inner tanks can better remove harmful substances in the odor, gradually reducing the concentration of harmful substances and improving the purification effect. Moreover, when the deodorizing inner tank is sprayed for deodorization, the demister can eliminate the water vapor and other mist coming out of the inner tank, keeping the next deodorizing inner tank dry, thereby improving the subsequent purification effect.
[0011] This demister includes demister packing and a high-pressure spray assembly. The demister packing can adsorb water vapor and aerosols carried by the passing odor, while the high-pressure spray assembly can perform timely high-pressure spray cleaning on the demister packing to remove biofilm and some hardened impurities attached to the packing, thereby ensuring continuous and efficient operation and improving the purification effect.
[0012] This demister is equipped with a pressure detection device. By detecting the pressure difference on both sides of the demister packing, the permeability of the packing is determined. If the pressure difference is large, the permeability is considered poor. In this case, the high-pressure spray assembly will spray and clean the demister packing to remove biofilm and impurities. This ensures that the demister returns to its optimal working state and further improves the purification efficiency and effect of the purifier.
[0013] Each deodorizing inner liner is equipped with a demister, and each demister has an air pressure detection device. This allows the demister to be checked for blockage by monitoring the pressure difference between the devices. The device can then selectively clean the demisting filler in each demister. This design is highly intelligent, provides precise self-cleaning, and is very effective.
[0014] In the aforementioned automatic flushing and purification device, the bottom and top of the deodorizing inner liner are respectively provided with an air inlet and an exhaust outlet, the top of the deodorizing inner liner is fixed to the top plate of the tower shell, and the demister is exposed on the outside of the top plate of the tower shell and is connected to the exhaust outlet.
[0015] The deodorizing inner liner is designed with bottom air intake and top exhaust. This allows the odor to pass through from bottom to top and come into even contact with the adsorption material in the deodorizing inner liner. Furthermore, large particles carried in the odor are less likely to pass through from bottom to top due to their own gravity, thus further improving the purification efficiency.
[0016] The deodorizing inner liner is fixed to the top plate of the tower shell, while the demister is installed on the top plate and exposed. The internal space of the tower shell is only used to accommodate the deodorizing inner liner, which significantly reduces the height and saves materials, making it easier for users to install and use. Secondly, the direct exposure of the demister allows for convenient maintenance and timely replacement of its internal demisting packing, ensuring the demister's operational status and guaranteeing the stability and purification effect of the purification equipment.
[0017] In the aforementioned automatic flushing and purification device, the vertical projected area of the demister is less than half the vertical projected area of the deodorizing inner liner.
[0018] This demister is much smaller than the deodorizing inner liner and even smaller than the tower shell. This type of demister is directly exposed to the outside space, taking up less space and saving top space.
[0019] In the aforementioned automatic flushing and purification device, the demister includes a mounting housing with openings at both the top and bottom. The bottom opening of the mounting housing is connected to the exhaust port on the deodorizing inner liner, and the top opening of the mounting housing is connected to the air inlet on the next sequential deodorizing inner liner via a channel.
[0020] The deodorizing inner liner of this application is arranged in sequence, and each demister is connected to the exhaust port on the inner liner. The top opening of the demister on the previous inner liner is connected to the channel, which is connected to the air inlet on the next inner liner. Thus, one inner liner with one demister forms a purification unit. Multiple purification units can repeatedly purify the odor, gradually reducing the content of harmful substances in the odor, thereby improving the purification effect.
[0021] In the aforementioned automatic flushing and purification device, the channel includes channel section one and channel section two. Channel section one is located between the bottom plate of the tower shell and the bottom of the deodorizing inner liner. Channel section two is located between two adjacent deodorizing inner liners. Channel section two is connected to the air inlet of the deodorizing inner liner. Channel section one and channel section two are interconnected. The outlet of the previous demister is connected to channel section two through a pipe.
[0022] In the aforementioned automatic flushing and purification equipment, both the demisting filler and the high-pressure spray assembly are disposed inside the mounting housing, with the high-pressure spray assembly positioned above the demisting filler.
[0023] The high-pressure spray assembly is positioned above the demister packing. The sprayed water, along with the washed biofilm and impurities, can be directly discharged downwards from the bottom opening of the mounting housing, avoiding secondary clogging and maintaining the permeability of the compact demister, thereby improving the purification effect.
[0024] In the aforementioned automatic rinsing and purification equipment, the high-pressure spray assembly includes a spray pipe and several high-pressure swirl nozzles. The spray pipe is arranged above the demisting filler along the length of the mounting housing, and the several high-pressure swirl nozzles are arranged at intervals along the spray pipe.
[0025] The spray pipe is horizontally installed above the demisting packing material. Multiple high-pressure swirl nozzles are arranged at intervals to fully cover the entire demisting packing material. The high-pressure water flow can thoroughly rinse the demisting packing material, improving the cleaning effect.
[0026] In the aforementioned automatic flushing and purification device, a drawer-type stuffing box is connected to the mounting housing. The bottom and top plates of the stuffing box are both perforated plates with a hole diameter of 8mm-12mm. The stuffing box is slidably connected to the mounting housing via a slide rail. The demisting filler is filled inside the stuffing box.
[0027] The demisting packing material of this application is filled in a pull-out packing box. The demisting packing material can be quickly removed and replaced by pulling it out. Replacement can be carried out quickly without stopping the machine, thus ensuring the purification effect.
[0028] Multiple demisting fillers on the multiple demisters can be replaced by pulling them out. This way, the equipment does not need to be stopped when replacing the fillers one by one, and the equipment as a whole can always maintain a good purification state.
[0029] In the aforementioned automatic flushing and purification equipment, the air pressure detection element is a differential pressure transmitter. The differential pressure transmitter has two detection probes, one of which is located in the demister on the side where the high-pressure spray assembly is located, and the other detection probe extends to both sides of the demister packing and is set near the deodorizing inner liner.
[0030] The air pressure detection device in this application is a differential pressure transmitter. One detection probe of the differential pressure transmitter extends into the demisting packing, which can measure the air pressure inside the demisting packing in real time and compare it with the air pressure at the outlet. This provides high lateral accuracy and is more intuitive.
[0031] In the aforementioned automatic flushing and purification equipment, the main body of the differential pressure transmitter is fixed on the outer surface of the mounting housing, and both of the aforementioned detection probes extend to the inner side of the mounting housing.
[0032] The differential pressure transmitter of this application is installed on the outside of the demister, with only the detection probe inserted into the inside of the demister. This can prevent the differential pressure transmitter from being corroded by the water mist inside the demister, effectively improving its service life. Moreover, the exposed differential pressure transmitter is easy to maintain and replace.
[0033] In the aforementioned automatic rinsing and purification equipment, the spray water pressure of the high-pressure spray assembly is 2-4 bar.
[0034] The spray water pressure is 2-4 bar, which is sufficient to effectively rinse the biofilm and improve cleaning efficiency and effect.
[0035] In the aforementioned automatic flushing and purification equipment, the demisting packing material is a Pall ring or a multi-faceted hollow sphere.
[0036] The beneficial effects of this utility model are:
[0037] 1. This equipment divides the deodorizing packing into two or more independent deodorizing inner tanks. Each deodorizing inner tank is equipped with a demister and a pressure detection device to form multiple purification units. Each purification unit can purify independently and be automatically flushed. By connecting multiple purification units in series, multi-stage deodorization can be achieved, gradually reducing the content of harmful substances in the odor and improving the purification effect.
[0038] 2. Each deodorizing inner tank is equipped with a demister, and each demister has an air pressure detection device. This allows the demister to be checked for blockage by measuring the pressure difference of each device, and the demisting filler in each demister can be cleaned selectively. This design ensures precise and effective self-cleaning.
[0039] 3. The deodorizing inner liner is fixed to the top plate of the tower shell, while the demister is installed on the top plate and exposed. This design effectively reduces the height of the tower shell, minimizes space occupation, and facilitates user installation and use. Attached Figure Description

[0044] like Figure 1 The illustrated automatic flushing and purification device includes a square-shaped tower shell 1 with six sides, which is low in height and reduces installation difficulty. The tower shell 1 has a chamber 11, within which two deodorizing inner liner 2 are arranged horizontally at intervals. Each deodorizing inner liner 2 contains a portion of deodorizing packing material. Unlike conventional devices that concentrate all packing material in a large chamber, this device divides the deodorizing packing material into two or more independent deodorizing inner liner 2, which are then connected in series. Odorous gas enters and passes through each liner sequentially, achieving multi-stage deodorization and improving purification efficiency. A gap is left between adjacent deodorizing inner liner 2, forming a channel segment 13. The bottom of the outer shell of the deodorizing inner liner 2 has a grille, forming an air inlet 21. The grille supports the deodorizing packing material and provides good passage. A gap exists between the bottom of the deodorizing inner liner 2 and the bottom plate of the tower shell 1, forming a channel segment 12 communicating with the air inlet 21. Channel segment 12 and channel segment 13 are connected by sheet metal to form a complete channel. The top of the deodorizing inner liner 2 coincides with the top plate of the tower shell 1. An exhaust port 22 is opened on the top of the deodorizing inner liner 2, i.e., the top plate of the tower shell 1. A demister 3 is installed at the exhaust port 22. The demister 3 is connected to the aforementioned channel section 13 via a pipe 14. This connects two adjacent deodorizing inner liners 2. The structure of the deodorizing inner liner 2 with air intake at the bottom and exhaust at the top ensures that odorous gas passing from bottom to top can fully and evenly contact the adsorption material. Large particles carried in the odorous gas are less likely to pass through from bottom to top due to their own gravity, further improving purification efficiency. It should also be noted that the inlet of channel section 13 of the first deodorizing inner liner 2 does not have a demister 3 connected, thus serving as the odor inlet. Each deodorizing inner tank 2 is equipped with an independent demister 3 at its outlet. The demister 3 can remove the water vapor and aerosols carried in the odor, playing a secondary purification role and improving the purification effect. This design of multiple demisters 3 combined with multiple deodorizing inner tanks 2 can better remove most of the water vapor and aerosols contained in the odor, achieving gradual purification and improving the purification effect.
[0045] like Figure 1The installation method of the demister 3 is as follows: A square exhaust port 22 is provided on the top of the deodorizing inner liner 2 (i.e., the top plate of the tower shell 1). The demister 3 includes a mounting housing 33. The bottom opening of the mounting housing 33 fits into the square exhaust port 22, and the two are joined to form a seal. The joining can be done by welding. The length of the demister 3 is only 1 / 3 of the length of the deodorizing inner liner 2, and the demister 3 is exposed on the outside of the top plate of the tower shell 1. The size of the demister 3 is much smaller than that of the deodorizing inner liner 2, and even smaller than that of the tower shell 1. This direct exposure of the demister 3 reduces the height of the tower shell 1, lowers the headroom, facilitates installation, and saves production costs. Furthermore, the direct exposure of the demister 3 allows users to easily maintain it and replace the internal demister packing 31 in a timely manner, thereby ensuring the working condition of the demister 3 and ensuring the stability and purification effect of the purification equipment.
[0046] like Figure 2 and Figure 3 The specific structure of the demister 3 shown is as follows: A horizontal slide rail is provided on the mounting housing 33, and a stuffing box 34 is slidably connected to the horizontal slide rail. The stuffing box 34 is opened and closed by horizontal pulling. The top and bottom of the stuffing box 34 are assembled from perforated plates with a hole diameter of 8-12mm. The top plate is a detachable connection structure, directly covering the box body and being limited by its outer edge contacting the mounting housing 33. The stuffing box 34 is filled with Pall rings or multi-faceted hollow spheres as demister packing 31, which can purify water vapor and aerosols of the passing odorous gas to ensure the overall purification effect. The height of the demister packing 31 is preferably ≤50cm, and the particle size of the packing is 2-3cm. The mounting housing 33 has slide rails 35 on both sides of the installation position of the stuffing box 34. The stuffing box 34 slides with the slide rails 35, and its pull-out stroke is ≥80cm. When the stuffing is severely scaled, the stuffing box 34 can be pulled out through the drawer structure for manual cleaning or replacement of the stuffing. The demisting stuffing layer can be quickly cleaned or replaced manually without stopping the system.
[0047] like Figure 1 , Figure 2 and Figure 3The demister 3 shown also includes a high-pressure spray assembly 32 positioned above the packing box 34. The high-pressure spray assembly 32 performs timely high-pressure spray cleaning of the demister packing 31, eliminating biofilm and hardened impurities adhering to the packing, thus ensuring overall purification efficiency. The sprayed water, along with the washed-off biofilm and impurities, flows directly downwards from the bottom opening of the mounting housing 33 into the deodorizing inner tank 2, and further falls to the bottom of the tower for discharge, resulting in good waste removal and preventing secondary blockage, thereby improving purification efficiency. The high-pressure spray assembly 32 is preferably a high-pressure swirl nozzle 322. A spray pipe 321 is horizontally installed above the packing box 34, with multiple high-pressure swirl nozzles 322 evenly distributed on the spray pipe 321. The number of high-pressure swirl nozzles 322 can be adjusted according to the packing length. The spray direction of the high-pressure swirl nozzles 322 is towards the demister packing 31. The spray pipe 321 is connected to a flushing water system (not shown in the figure). The flushing water system includes a water pump, water pipes, and an electromagnetic control valve. Tap water is used for flushing and is delivered to the spray pipe 321 through the water pipes. The electromagnetic control valve controls the flow rate and pressure of the flushing water. High-pressure water flow ensures thorough flushing of the demisting packing 31, improving the cleaning effect. The flushing water pressure is 2-4 bar, which can be adjusted by a pressure valve. This ensures that biofilm and impurities are effectively flushed away. This requirement guarantees the flushing effect and avoids incomplete flushing due to insufficient pressure.
[0048] Furthermore, the demister 3 is connected to a pressure detection element 4. The permeability of the demister packing 31 is determined by detecting the pressure difference across it. If the pressure difference is large, the permeability is considered poor, triggering an alarm and opening the solenoid valve controlled by the main unit to spray and clean the demister packing 31, removing biofilm and impurities. This ensures the demister 3 is always in optimal working condition. Each demister 3 is equipped with a pressure detection element 4, allowing the pressure difference feedback from each element to determine the blockage status of each demister 3. Figure 1If the left-side air pressure sensor 4 alarms while the right-side air pressure sensor is functioning normally, then the left-side demister 3 needs self-cleaning. Conversely, if the left-side air pressure sensor 4 does not alarm while the right-side air pressure sensor 4 alarms, then the right-side demister 3 needs self-cleaning. If the right-side demister alarms after self-cleaning, then the left-side demister also needs self-cleaning. This selective cleaning of the demister packing 31 on each demister 3 ensures precise and effective self-cleaning. As a preferred option, the pressure detection component 4 is preferably a differential pressure transmitter (this is an outsourced component and a mature existing technology, so it will not be elaborated on here). The differential pressure transmitter has two detection probes 41. One detection probe 41 is located inside the demister 3 on the side where the high-pressure spray assembly 32 is located, and the other detection probe 41 is inserted into the demister packing 31 and set near the deodorizing inner liner 2. It is used to monitor the operating resistance of the demister device in real time. When the resistance exceeds the set threshold of 200±50Pa, the electromagnetic control valve is triggered to start the self-flushing device. This design can accurately measure the air pressure passing through the demister packing 31 in real time and compare it with the air pressure at the outlet. This lateral accuracy is high and more intuitive. The main body of the differential pressure transmitter is fixed on the outer surface of the mounting housing 33, and both detection probes 41 are inserted laterally into the inner side of the mounting housing 33. The differential pressure transmitter of this application is installed on the outside of the demister 3, with only the detection probe 41 inserted into the inside of the demister 3. This can prevent the differential pressure transmitter from being corroded by the water mist inside the demister 3, effectively improving its service life. Moreover, the exposed differential pressure transmitter is easy to maintain and replace.
[0049] Operating mode: When the operating resistance of demister 3 rises to the set value, the self-flushing device is activated, and the water pump in the flushing water system starts, delivering water from the water tank at the bottom of the purification device to the spray pipe 321. The water then flushes the packing material in the packing box 34 through the high-pressure cyclone nozzle 322. Biofilm, impurities, etc., are flushed to the bottom of the tower and discharged through the drainage system (not shown in the figure), restoring the resistance of demister 3 to the normal range. When the packing material is severely scaled, the packing box 34 can be pulled out through the drawer-type structure for manual flushing or replacement of the packing material.
[0050] like Figure 1The specific structure of the deodorizing inner liner 2 shown is as follows: The deodorizing inner liner 2 of this application includes an open outer shell. A grid for support is installed and fixed at the air inlet 21 at the bottom of the outer shell. Filler is filled above the grid, preferably a composite activated carbon layer. The filling height of the composite activated carbon layer reaches half of the outer shell. A spray system 5 is arranged above the activated carbon layer. The spray system 5 includes a water supply pipe and spray nozzles. The spray system 5 can be connected to chemical neutralization reaction consumables or to flushing water to neutralize or adsorb harmful components in the odor. The top plate of the outer shell is the top plate of the tower shell 1. A small exhaust port 22 is opened at the top of the outer shell and is adapted to connect with the demister 3. After the odor enters the entire equipment, it passes through the first composite activated carbon layer, the first spray system, the first demister, the second activated carbon layer, the second spray system, and the second demister in sequence. The odor undergoes step-by-step reaction and adsorption, resulting in a high purification rate and good purification effect.
