Technical Field
[0001] The utility model relates to the technical field of MBR membrane cleaning, and more specifically to a continuous membrane component automatic cleaning device. Background Art
[0002] With the acceleration of industrialization and urbanization, wastewater treatment has become an increasingly important environmental issue. Traditional wastewater treatment methods such as activated sludge method and sedimentation tank treatment process have problems such as poor treatment effect, large footprint, and high sludge production. In order to overcome these shortcomings, membrane technologies such as membrane bioreactor (MBR) came into being and became an efficient and resource-saving wastewater treatment method. Membrane treatment system, as a wastewater deep treatment unit, is widely used at the end of the wastewater treatment system. However, as a deep treatment unit, the membrane system is easily blocked by suspended matter or impurities in the wastewater. Regular cleaning is required to restore its treatment capacity, reduce membrane aging and damage, and extend the service life of the membrane.
[0003] Currently, there are two main cleaning modes for membrane components: shift cleaning and in-situ cleaning. Both modes use chemical immersion. The in-situ cleaning is not strong enough and the treatment energy cannot be restored to its original state. The shift cleaning process is cumbersome and also increases the operating cost of the wastewater treatment station.
[0004] Therefore, it is an urgent problem to be solved by technicians in this field to provide a continuous membrane module automatic cleaning equipment with higher cleanliness, high degree of automation, and simple operation. Utility Model Content
[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a continuous membrane component automatic cleaning device with a high degree of automation, simple operation, and the ability to effectively reduce the operating and maintenance costs of a wastewater treatment system.

[0008] Preferably, the interior of the box is divided into a flushing area, a hydrochloric acid cleaning area, a first water cleaning area, a secondary sodium cleaning area, a second water cleaning area and a soaking area in sequence, and the above-mentioned areas are respectively provided with a cleaning liquid inlet on the side wall of the box, and the above-mentioned areas are respectively provided with an emptying port on the bottom of the box, and an ultrasonic cleaning machine is installed at the bottom of the above-mentioned areas.

[0012] It can be seen from the above technical solution that compared with the prior art, the utility model adopts a combination of chemical cleaning and physical cleaning to more efficiently clean the membrane components, thereby restoring the membrane's processing capacity to a greater extent. The membrane component cleaning equipment is highly integrated, highly automated, and easy to operate.

[0018] Embodiment 1
[0019] A continuous membrane module automatic cleaning device, such as Figure 1 to Figure 2 As shown, it includes a box body 1, a cleaning liquid inlet 2, an aeration pipe 3, a fan 4, a control box 5, an emptying port 13, an ultrasonic cleaning machine 14 and a hoisting cleaning mechanism. The aeration pipe 3 is installed in the box body 1, and the aeration pipe 3 is connected to the fan 4 outside the box body 1. The ultrasonic cleaning machine 14 is installed at the bottom of the box body 1, and the hoisting cleaning mechanism is installed above the box body 1. The control box 5 is arranged outside the box body 1, and the control box 5 is connected to the fan 4, the ultrasonic cleaning machine 14 and the hoisting cleaning mechanism circuit. The cleaning liquid inlet 2 is opened on the side wall of the box body 1, and the emptying port 13 is opened at the bottom of the box body 1.
[0020] In order to further optimize the above scheme, the interior of the box body 1 is divided into a flushing area 6, a hydrochloric acid cleaning area 7, a first water cleaning area 8, a secondary sodium cleaning area 9, a second water cleaning area 10 and a soaking area 11 in sequence, and the above-mentioned areas are respectively provided with a cleaning liquid inlet 2 on the side wall of the box body 1, and the above-mentioned areas are respectively provided with an emptying port 13 on the bottom of the box body 1, and an ultrasonic cleaning machine 14 is installed at the bottom of the above-mentioned areas, and each area is provided with an independent cleaning liquid inlet 2 and an emptying port 13 to facilitate the addition and discharge of the cleaning liquid.
[0021] In order to further optimize the above scheme, the hoisting and cleaning mechanism includes an MBR membrane 15, a sliding rod 16 and a hook 17. The sliding rod 16 is installed above the box body 1. The hook 17 is slidably connected to the sliding rod 16. The MBR membrane 15 is hoisted on the hook 17. By sliding the sliding rod 16, the membrane assembly can be easily moved to different cleaning areas.
[0022] In order to further optimize the above solution, the aeration pipe 3 is a "U"-shaped pipe, which can not only increase the flow range of the airflow, but also reduce the resistance of the airflow in the pipe, thereby improving the cleaning efficiency.
[0023] In order to further optimize the above solution, a control valve 12 is provided between the fan 4 and the aeration pipe 3. A control valve 12 is also provided between the fan 4 and the aeration pipe 3, so that the intensity and flow of the airflow can be adjusted according to actual needs.
[0024] In order to further optimize the above scheme, an ultrasonic cleaning machine 14 is installed at the bottom of the box 1. This is a device that uses high-frequency ultrasonic waves to produce cavitation effect in the cleaning liquid. The cavitation effect can produce a strong impact force to quickly peel off the dirt and impurities on the surface of the membrane component to achieve a deep cleaning effect. At the same time, the ultrasonic cleaning machine 14 can also improve the penetration ability of the cleaning liquid, making the cleaning more thorough.
[0025] In order to further optimize the above scheme, the aeration pipe 3 installed in the box 1 is connected to the external fan 4 to form a gas-liquid mixed flow to aerate and clean the membrane assembly. Aeration not only helps to loosen and peel off the dirt on the membrane surface, but also increases the oxygen content in the solution and promotes the oxidation decomposition process of microorganisms.
[0026] Working principle: After the device is started, the blocked membrane assembly is first rinsed with clean water in the rinse area 6 through the hook 17 to wash away large particles of impurities, and then soaked in the hydrochloric acid cleaning area 7 to remove the substances attached to the surface of the membrane fibers through chemical reaction, and then rinsed in the water cleaning area 8 to remove the substances in the chemical reaction, and then oxidized in the secondary sodium cleaning area 9 and rinsed in the water cleaning area 10 in turn, and finally soaked in the soaking area 11; ultrasonic waves are installed at the bottom of each cleaning area for physical cleaning, and the cleaning liquid enters the cleaning area from the cleaning liquid inlet 2, and the waste liquid after cleaning is discharged from the drain port 13.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
