Description

Technical Field

[0001] The utility model relates to the technical field of aerators for sewage and wastewater treatment, in particular to a novel aerator. Background Art

[0002] Aeration technology operates on a very simple principle, requiring minimal environmental or technical expertise. Its ease of use makes it widely adopted, and it is widely used in the pretreatment and biochemical treatment stages of wastewater treatment. Furthermore, aeration systems release only oxygen into the water, preventing secondary pollution and making it an environmentally friendly process.

[0003] Due to the high energy consumption of air aeration, which generally accounts for 45%-75% of the total energy consumption of sewage treatment plants, the method of blower microporous aeration is now mostly used, that is, air is pressed into the air pipeline through a blower and sent to the aerator, and dispersed into the water in the form of microbubbles. The microbubbles rise from the bottom to the top, prompting oxygen to fully dissolve in the water, which can increase the dissolved oxygen content in the water.

[0004] Existing aerators are mainly divided into two types: tube aerators and disc aerators. Their materials are mainly rubber, silicone, corundum and titanium alloy. Both can play the role of oxygenating aeration, but their oxygen transfer efficiency is only 5%-10%. They have problems such as large pore size, large bubbles, low transmission efficiency, short life and easy clogging. Utility Model Content

DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The following will further describe the technical solution of the present invention in conjunction with the drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods.

In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", etc. indicating an orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0029] In one embodiment, a novel aerator includes: a vent member, a mounting member, and a polyethylene microporous aeration membrane, wherein the vent member is provided with a ventilation channel, and a vent hole is provided on the side wall of the ventilation channel, the mounting member is connected to the vent member, and the polyethylene microporous aeration membrane is arranged on the mounting member, and an aeration cavity is formed between the polyethylene microporous aeration membrane and the mounting member, and the aeration cavity is connected to the ventilation channel through the vent hole.

[0030] In this embodiment, a vent is connected to a mounting member, a polyethylene microporous aeration membrane is disposed on the mounting member, and an aeration chamber is formed between the polyethylene microporous aeration membrane and the mounting member. The ventilation channel on the vent is connected to the aeration chamber through the vent. When pressurized aeration is performed, air can flow into the aeration chamber through the ventilation channel and vent of the vent, and finally pass through the polyethylene microporous aeration membrane for outward aeration. Because the polyethylene microporous aeration membrane has high membrane porosity, large specific surface area, low aeration resistance, near-zero pore deformation, acid, alkali resistance, and high salt resistance, the airflow through the polyethylene microporous aeration membrane can achieve micro-nano bubble aeration, thereby improving the oxygen transmission efficiency. At the same time, during pressurized aeration, it is not easily deformed or clogged, and has a long service life.

[0031] In one embodiment, the polyethylene microporous aeration membrane is provided with a filling slot, which is filled with a composite piezoelectric catalytic material layer. Specifically, a plurality of filling slots are provided, each of which is evenly distributed on the polyethylene microporous aeration membrane. Each filling slot contains a composite piezoelectric catalytic material layer, which is a copper oxide / zinc oxide composite piezoelectric catalytic material layer. This composite piezoelectric catalytic material carried on the polyethylene microporous aeration membrane not only provides aeration and oxygenation, but also oxidizes and decomposes organic pollutants in water.

[0032] In this embodiment, when the airflow passes through the polyethylene microporous aeration membrane, the pressure causes a piezoelectric catalytic effect to be generated in the polyethylene microporous aeration membrane. The polyethylene microporous aeration membrane is in an unbalanced heterogeneous charge state and can release active oxygen into the water body. The bubbles have a large number of highly active free radicals, which can undergo redox reactions when in contact with organic pollutants, thereby oxidizing and decomposing organic pollutants in the water body, and removing organic matter in the water body, thereby reducing the chemical oxygen demand, biochemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus of the water body. It can replace traditional advanced oxidation processes such as Fenton, that is, it can degrade organic pollutants in the water body through the active oxygen generated by aeration with a new aerator, reducing reagent consumption, sludge production and tank area, and reducing operating costs.

[0033] In one embodiment, Figure 1 and Figure 2As shown, the ventilator is a connecting pipe 120, and the ventilation channel is opened inside the connecting pipe 120. The mounting member includes: a first mounting plate 221 and a second mounting plate 222. The first mounting plate 221 is arranged on the first end of the connecting pipe 120, and the second mounting plate 222 is connected to the second end of the connecting pipe 120. The polyethylene microporous aeration membrane 300 is surrounded and covered on the first mounting plate 221 and the second mounting plate 222. The polyethylene microporous aeration membrane 300, the first mounting plate 221 and the second mounting plate 222 are spaced apart to form the aeration chamber 310. Specifically, the first mounting plate 221 and the second mounting plate 222 are spaced apart, the first end of the connecting tube 120 is connected to the first mounting plate 221, and at least part of the connecting tube 120 passes through the first mounting plate 221, the second end of the connecting tube 120 is connected to the second mounting plate 222, the polyethylene microporous aeration membrane 300 is wound to form a cylindrical structure to cover the connecting tube 120, and the two ends are respectively connected to the first mounting plate 221 and the second mounting plate 222 to form a new aerator 10 with a tubular structure. In this way, when pressurized aeration is performed, air can move into the aeration chamber 310 through the ventilation channel and the ventilation holes 121 of the connecting tube 120, and finally pass through the polyethylene microporous aeration membrane 300 to be aerated outward, and aeration and oxygen supply can be performed outward in the form of a tubular aerator. It is worth noting that, according to the needs of water aeration treatment, two or more new aerators with tubular structures can be arranged and combined in different ways. For example, two or more new aerators with tubular structures can be combined together through a three-way connector or a five-way connector. For another example, multiple new aerators with tubular structures can be evenly distributed on the connecting pipe rack and arranged to form an aeration assembly with a planar structure or a multi-layer three-dimensional structure, so as to better aerate the water body.

[0034] In one embodiment, a first connection hole is formed on the first mounting plate 221. The first mounting plate 221 is sleeved on the first end of the connecting tube 120 through the first connection hole. The first end of the connecting tube 120 is connected to the side wall of the first connection hole. An air inlet is formed on the first end of the connecting tube 120, and the air inlet is connected to the ventilation channel. Specifically, by forming the first connection hole on the first mounting plate 221, the first end of the connecting tube 120 can be inserted into the first connection hole, and the first end of the connecting tube 120 protrudes to the outside of the first connection hole. The air inlet formed on the first end of the connecting tube 120 is used to connect to an external blower device, thereby pressurizing air into the ventilation channel.

Specifically, the second connection hole on the second mounting plate 222 is aligned with the threaded hole on the second end of the connecting tube 120. The first end of the screw 400 passes through the second connection hole and is then threaded into the threaded hole. The second end of the screw 400 abuts against the outer edge of the second connection hole, allowing the second mounting plate 222 to be connected to the connecting tube 120 in a threaded manner.

[0036] In one embodiment, Figure 2 As shown, a first sealing gasket 510 is provided on the first mounting plate 221, and the outer edge of the first sealing gasket 510 abuts against the polyethylene microporous aeration membrane 300. Specifically, the first sealing gasket 510 is located within the aeration chamber 310 and is provided on the first mounting plate 221. The outer edge of the first sealing gasket 510 abuts against the polyethylene microporous aeration membrane 300, thereby enhancing the airtightness of the connection between the polyethylene microporous aeration membrane 300 and the first mounting plate 221, allowing air to better pass through the polyethylene microporous aeration membrane 300 for outward aeration.

[0037] In one embodiment, Figure 2 As shown, a second sealing gasket 520 is provided on the second mounting plate 222, and the outer edge of the second sealing gasket 520 abuts against the polyethylene microporous aeration membrane 300. Specifically, the second sealing gasket 520 is located within the aeration chamber 310 and is provided on the second mounting plate 222. The outer edge of the second sealing gasket 520 abuts against the polyethylene microporous aeration membrane 300, thereby enhancing the airtightness of the connection between the polyethylene microporous aeration membrane 300 and the second mounting plate 222, allowing air to better pass through the polyethylene microporous aeration membrane 300 for outward aeration.

[0038] In one embodiment, the aeration chamber 310 has a circular cross-section. Specifically, the aeration chamber 310 is a cylindrical cavity, which can increase the area of the sidewall of the aeration chamber 310, allowing air to better pass through the polyethylene microporous aeration membrane 300 for outward aeration, better achieving micro-nano bubble aeration and improving oxygen transmission efficiency.

[0039] In one embodiment, Figure 3 and Figure 4As shown, the ventilation member is a ventilation tube 110, the ventilation channel 100 is opened inside the ventilation tube 110, a vent 111 is opened on the first end of the ventilation tube 110, and the vent 111 is communicated with the ventilation channel 100, the mounting member is a mounting plate 210, the mounting plate 210 is opened with a mounting hole, the second end of the ventilation tube 110 is inserted into the mounting hole, and the second end of the ventilation tube 110 is connected to the side wall of the mounting hole, the polyethylene microporous aeration membrane 300 is coated on the mounting plate 210, and the polyethylene microporous aeration membrane 300 and the mounting plate 210 are spaced apart to form the aeration chamber.

In this way, when pressurized aeration is performed, air can move into the aeration chamber through the ventilation channel 100 and the vent hole 121 of the vent tube 110, and finally pass through the polyethylene microporous aeration membrane 300 to be aerated outward, and aeration and oxygen supply can be performed outward in the form of a disc aerator. It is worth noting that, according to the needs of water aeration treatment, multiple new disc-type aerators can be arranged and combined in different ways. For example, multiple new disc-type aerators can be evenly distributed on the connecting pipe rack and arranged to form a plane structure or a multi-layer three-dimensional aeration assembly, so as to better aerate the water body.

The ventilation channel on the vent member is connected to the aeration chamber through the vent hole, and air can be transported into the aeration chamber through the vent member.

Furthermore, by providing a copper oxide and zinc oxide composite piezoelectric catalytic material layer on the polyethylene microporous aeration membrane, when the airflow passes through the polyethylene microporous aeration membrane, the pressure causes the polyethylene microporous aeration membrane to produce a piezoelectric catalytic effect, which can release active oxygen into the water body, oxidizing and decomposing organic pollutants in the water body, and effectively degrading organic matter in the water body.
