Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to an integrated membrane module. Background Technology

[0002] Membrane modules are commonly used in wastewater treatment. Existing membrane modules generally include a membrane curtain and an aeration device, but these are separate structures requiring separate installation, resulting in significant manpower waste. During operation, contaminants accumulate on the surface of the membrane fibers, affecting the filtration efficiency. To reduce surface fouling, aeration scrubbing is the most widely used method to mitigate membrane fouling. It relies on the impact of airflow to remove contaminants from the membrane fiber surface, thus cleaning it. Aeration scrubbing is primarily achieved through aeration devices. Traditional aeration devices include an aeration fan and aeration pipes with aeration holes. Airflow impacts the membrane fibers through these holes, but this aeration method typically involves relatively low airflow and limited impact force, resulting in incomplete cleaning of the contaminants on the membrane fiber surface. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an integrated membrane module. The technical solution adopted is: an integrated membrane module, characterized in that it includes: a membrane curtain, wherein water collection chambers are provided at both the upper and lower ends of the membrane curtain, and water production channels communicating with the upper and lower water collection chambers are provided on the left and right sides, and membrane fibers are provided between the upper and lower water collection chambers, and a slot is provided at the bottom of the lower water collection chamber; a large bubble pulse aeration device, wherein the top of the large bubble pulse aeration device has a buckle that matches the slot at the bottom of the lower water collection chamber, and the membrane curtain and the pulse aeration device are detachably connected through the slot and the buckle.

[0004] A further technical feature of this utility model is:

[0005] The large bubble pulse aeration device includes: a shell, comprising a front side plate, a rear side plate, a left side plate, a right side plate, and a top plate, the bottom of which is open, and a buckle matching the bottom groove of the lower water collection chamber is provided on the top plate of the shell; an air inlet groove slidably connected to the shell, the air inlet groove being a rectangular groove with an open bottom, one end of which is provided with an air inlet pipe, and an air outlet hole on the side of the air inlet groove; an air collection chamber fixed to the top plate of the shell and extending into the internal cavity of the shell, the top surface of which is provided with an air inlet notch; an air distribution channel placed on the top plate of the shell, the air distribution channel and the air collection chamber being correspondingly arranged, and there is a gap between the bottom of the air distribution channel and the bottom of the air collection chamber; and a disperser placed on the outer side of the top plate of the shell and communicating with the air distribution channel.

[0006] The gap between the bottom of the gas distribution channel and the bottom of the gas collection chamber is 5mm-10mm.

[0007] The air intake slot is provided with a slide rail, and the left and right side plates of the housing are provided with openings that match the air intake slot. The openings are also provided with slide grooves that match the slide rails.

[0008] The shell, air inlet slot, air collection chamber, air distribution channel, and diffuser are an integral structure.

[0009] The air outlets on the side of the air inlet slot are on the same horizontal plane.

[0010] Overflow holes are provided below the front and rear side plates of the housing.

[0011] The beneficial effects of this utility model are as follows: Since the membrane curtain and pulse aeration device of this integrated membrane module are detachably connected via slots and buckles, installation is convenient and separate construction is no longer required, saving a significant amount of manpower. Furthermore, the aeration device employs a large-bubble pulse aeration device. An air inlet is provided at the top of the gas collection chamber, which is closed on all sides and at the bottom. Gas enters the top of the gas collection chamber through the air inlet and gradually accumulates and compresses. The increasing gas volume causes the gas-liquid interface to gradually move downwards until the gas enters the gas distribution channel. Upon entering the gas distribution channel, a siphon effect is formed, allowing the gas to quickly reach the disperser and form large bubbles that flush the membrane fibers in the membrane curtain from both sides of the lower water collection chamber. The siphon effect also causes liquid to rush into the gas collection chamber rapidly. This repeated process forms pulse-like large bubbles that scrub the membrane fibers. The bursting of these large bubbles causes localized turbulence in the fluid, creating shear force and disturbance on the membrane fiber surface. The larger the bubble volume, the greater the impact force, thus achieving a better purging effect on the membrane fibers. Moreover, the structure of the gas collection chamber ensures that the gas pressure reaching the gas distribution channel is essentially the same, preventing uneven gas distribution.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Reference Figures 1 to 4 In this embodiment, an integrated membrane module is characterized by comprising: a membrane curtain 1, wherein water collection chambers 11 are provided at both the upper and lower ends of the membrane curtain, and water production channels 12 communicating with the upper and lower water collection chambers 11 are provided on the left and right sides, and membrane fibers 13 are provided between the upper and lower water collection chambers, and a slot 14 is provided at the bottom of the lower water collection chamber; and a large bubble pulse aeration device 2, wherein the top of the large bubble pulse aeration device is provided with a buckle 214 that matches the slot at the bottom of the lower water collection chamber, and the membrane curtain 1 and the pulse aeration device 2 are detachably connected through the slot 14 and the buckle 214.

[0019] The large bubble pulse aeration device includes: a housing 21, which includes a front side plate, a rear side plate, a left side plate, a right side plate, and a top plate. The bottom of the housing 21 is open. A buckle 214 that matches the bottom slot 14 of the lower water collection chamber is provided on the top plate of the housing; an air inlet slot 22 that is slidably connected to the housing 21, which is a rectangular slot with an open bottom. An air inlet pipe 23 is provided at one end of the air inlet slot, and an air outlet 24 is provided on the side of the air inlet slot; an air collection chamber 25 that is fixed to the top plate of the housing and extends into the internal cavity of the housing, with an air inlet notch 26 on the top surface of the air collection chamber 25; an air distribution channel 27 that is placed on the top plate of the housing, which is correspondingly arranged with the air collection chamber 25, and there is a gap between the bottom of the air distribution channel 27 and the bottom of the air collection chamber 25; and a disperser 28 that is placed on the outer side of the top plate of the housing and communicates with the air distribution channel 27. In this embodiment, the gap between the bottom of the air distribution channel 27 and the bottom of the air collection chamber 25 is 5mm-10mm; a slide rail 29 is provided on the air inlet slot 22, and openings 211 matching the air inlet slot are provided on the left and right side plates of the housing, and a sliding groove 212 matching the slide rail is also provided at the opening; the air outlets 24 on the side of the air inlet slot 22 are on the same horizontal plane. Overflow holes 213 are provided below the front and rear side plates of the housing.

[0020] Because the membrane curtain 1 and pulse aeration device 2 of the integrated membrane module are detachably connected via slot 14 and buckle 214, installation is convenient and separate construction is no longer required, saving a lot of manpower. In addition, the aeration device adopts a large bubble pulse aeration device. The upper end of the gas collection chamber 25 is provided with an air inlet 26, and the sides and bottom are closed. The gas enters the top of the gas collection chamber from the air inlet 26 and gradually gathers and compresses. The increasing amount of gas causes the gas-liquid interface to gradually move downward until the gas enters the gas distribution channel 27. After the gas enters the gas distribution channel 27, a siphon effect is formed, which makes the gas quickly reach the top of the gas collection chamber. The liquid reaches the disperser 28, forming large bubbles that flow upwards from both sides of the lower water collection chamber 11 to wash the membrane fibers 13 in the membrane curtain 1. The siphon phenomenon also causes the liquid to rush into the gas collection chamber 25. This process is repeated to form pulsed large bubbles that scrub the membrane fibers. The bursting of these large bubbles will cause local turbulence in the fluid, forming shear force and disturbance force on the surface of the membrane fibers. The larger the volume of the bubble, the greater the impact force, which can achieve a better purging effect on the membrane fibers. Moreover, the structure of the gas collection chamber ensures that the gas pressure reaching the gas distribution channel is basically the same, and there will be no uneven gas distribution.

[0021] In addition, a slide rail 29 is provided on the air inlet groove 22, and openings 211 matching the air inlet groove 22 are provided on the left and right side plates of the housing 21. A sliding groove 212 matching the slide rail 29 is also provided at the opening 211. This structure facilitates installation. The lower end of the air inlet groove 22 is open, which overcomes the problem of mud accumulation and blockage in the perforated pipe. The air outlets 24 on the side of the air inlet groove 22 are on the same horizontal plane. Gas enters from the air inlet pipe 23 and gathers and compresses at the top of the air inlet groove 22. When the gas-liquid interface reaches the position of the air outlet 24, the gas pressure at the air outlet 24 is basically the same, realizing the uniform distribution of gas by the air inlet groove 22. Overflow holes 213 are provided below the front and rear side plates of the housing 21. When the gas distribution channel 27 is blocked, the gas fills the internal cavity of the housing 21 and reaches the overflow hole 213, where it is uniformly aerated.

[0022] In practical applications, the shell 1, air inlet groove 22, air collection chamber 25, air distribution channel 27, and disperser 28 can also be integral structures, integrally molded with materials such as ABS and polyvinyl chloride, which have the advantages of easy molding, high strength, and corrosion resistance, making them more suitable for wastewater treatment.

However, it is understood that, under the inventive concept of this utility model, those skilled in the art can make various changes and improvements to the above structure, including combinations of the technical features disclosed or claimed herein, as well as other combinations that explicitly include these features.
