Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to a plug-flow electrocatalytic oxidation industrial wastewater treatment device. Background Art

[0002] An electrocatalytic oxidation device is an auxiliary device used in the process of industrial wastewater treatment, which uses electricity as an oxidant and hydrogen peroxide, oxygen or ozone as oxidants for oxidation. The catalytic efficiency is stable, and the utilization rate of the oxidant is over 95%. It has been widely used in the field of wastewater oxidation.

[0003] In the existing electrocatalytic oxidation device during use, due to the fixed position of the electrode plates, the distance between the electrode plates is single, and the wastewater is basically in a static state in the wastewater treatment tank. This will lead to low electrocatalytic oxidation efficiency of the electrode plates on the wastewater. At the same time, as the use time of the electrode plates in the electrocatalytic oxidation device increases, foreign matter and impurities will accumulate on the surface of the electrode plates, making the electrocatalytic oxidation effect of the electrode plates worse, and further affecting the treatment effect of the electrocatalytic oxidation device on the wastewater. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a plug-flow electrocatalytic oxidation industrial wastewater treatment device to solve the problems of uneven and low electrocatalytic oxidation of wastewater by the fixed position of the electrode plates in the prior art.

[0005] To achieve the above utility model purpose, the technical solution of the utility model is:

[0006] A plug-flow electrocatalytic oxidation industrial wastewater treatment device includes a box body. One end of the box body is provided with a water inlet, and the other end is provided with a water outlet. The box body is filled with an oxidant. A plurality of cathode plates are arranged at the top and bottom of the box body. One end of the cathode plate is connected to the inner side wall of the box body, and the other end is suspended. An installation plate is horizontally arranged in the box body. An anode plate is hinged on the installation plate. The anode plate is located between adjacent cathode plates. A variable guide flow plate is hinged between the anode plate and the cathode plate on the same side. A driving component and a moving component are arranged outside the box body. One end of the installation plate passes through the box body and is connected to the moving component. The driving component is adapted to drive the moving component to drive the installation plate to move horizontally. The installation plate divides the inside of the box body into upper and lower groups for electrocatalytic oxidation, which can respectively perform electrocatalytic oxidation treatment on the wastewater flowing through the upper and lower parts, and accelerate the wastewater treatment efficiency. The driving component, the moving component and the installation plate are set to drive the anode plate, and then drive the variable guide flow plate to move synchronously or change the angle between the variable guide flow plate and the cathode plate. This not only disturbs the wastewater, making the wastewater always in a flowing state, but also changes the direction of the wastewater when flowing through each electrode plate, increases the contact with the cathode plate and the anode plate, increases the electrocatalytic effect, and also mixes quickly and evenly with the oxidant, greatly enhancing the oxidation effect.

[0007] Preferably, a number of small holes are formed in the variable guide baffle, and diversion grooves are respectively arranged on both sides facing the cathode plate. After the wastewater flushes onto the variable guide baffle, it is evenly divided through the small holes, so as to fully and quickly contact with the oxidant, improving the catalytic efficiency. The diversion grooves are provided to change the flow direction of part of the wastewater, slowing down the flow rate of the wastewater, thereby increasing the contact time between the wastewater and the oxidant and improving the electrocatalysis effect; at the same time, the diversion grooves can also intercept impurity particles in the wastewater and direct the impurity particles to the bottom of the box body.

[0008] Preferably, the moving assembly includes a gear and a rack that mesh with each other. A guide groove is arranged on the outer side wall of the box body, and the rack is slidably arranged in the guide groove; the rack is parallel to the mounting plate, and one end of the mounting plate passing through the box body is connected to the rack. The guide groove is provided to guide and support the rack, so that the mounting plate moves smoothly.

[0009] Preferably, an arc-shaped guide plate facing the water inlet is arranged at the suspended end of the cathode plate. The arc-shaped guide plate near the water inlet can respectively guide the incoming wastewater to the electrocatalytic oxidation areas at the upper and lower ends, reducing the dead water area of the water flow and accelerating the wastewater treatment efficiency; the remaining arc-shaped guide plates form a meandering flow channel with the electrode plates. When the wastewater flows, it passes through between each corresponding cathode and anode plate in turn, realizing multi-stage treatment and improving the water quality.

[0010] Preferably, the mounting plate is hollow inside, and a number of aerators are formed on the mounting plate. An aeration pump is arranged outside the box body, and an aeration pipe is connected between the air outlet of the aeration pump and the mounting plate. The contact time between the gas and the oxidant is strengthened by the way of pushing the flow, enhancing the wastewater treatment effect.

[0011] Preferably, the cathode plate is arranged vertically.

[0012] Preferably, cleaning mechanisms are arranged at both the top and the bottom of the box body. Each cleaning mechanism includes a first motor, a number of rotating shafts, a number of belt wheels and an endless belt. The rotating shafts are vertically arranged between adjacent cathode plates, and one end of each rotating shaft passes through the outside of the box body and is fixed on the corresponding belt wheel. The endless belt meshes with each belt wheel. The first motor is fixedly connected to one of the rotating shafts, and brush hairs in contact with the surface of the cathode plate are arranged on the circumferences of the rotating shafts. The first motor drives the belt wheels to rotate through the endless belt, and then drives each rotating shaft to rotate synchronously, scraping the dirt on the surface of the cathode plate with the brush hairs, avoiding the situation that dirt is generated on the surface of the cathode plate due to long-term operation, and improving the wastewater treatment efficiency; since the anode plate is in a moving state, there is less dirt on its surface; when the rotating shafts rotate, the wastewater is stirred, so that the wastewater and the oxidant are quickly and evenly mixed, increasing the electrocatalysis effect and greatly enhancing the effect of treating wastewater.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the mounting plate divides the inside of the box into upper and lower groups for electrocatalytic oxidation, which can respectively perform electrocatalytic oxidation treatment on the wastewater flowing through the upper and lower parts, accelerating the wastewater treatment efficiency; the driving assembly, moving assembly and mounting plate are provided to drive the anode plate, thereby driving the variable guide plate to move synchronously or changing the angle between the variable guide plate and the cathode plate. This not only disturbs the wastewater, keeping it in a flowing state all the time, but also changes the direction of the wastewater when it flows through each electrode plate, increasing the contact with the cathode plate and anode plate, enhancing the electrocatalytic effect, and also mixing quickly and evenly with the oxidant, greatly enhancing the oxidation effect.

[0015] 2. The variable guide plate in the present utility model can change the flow direction of part of the wastewater. The small holes on the variable guide plate can shunt the wastewater, accelerating the contact between the wastewater and the oxidant; the flow guide grooves on the variable guide plate can not only change the flow direction of part of the wastewater, slow down the flow speed of the wastewater, extend the contact time between the wastewater and the oxidant, but also intercept the impurity particles in the wastewater and direct the impurity particles to the bottom of the box.

[0016] 3. In the present utility model, the aeration pump, aerator, aeration pipe and rotating shaft are adopted, which can not only supplement air, but also stir the wastewater, generating a low-speed and strong water flow to play a role in pushing the flow, making the wastewater mix better with the oxidant and accelerating the wastewater treatment process.

[0017] 4. The cleaning mechanism is adopted in the present utility model to scrape the dirt on the surface of the cathode plate, avoiding the situation that dirt is generated on the surface of the cathode plate during long-term operation, and improving the electrocatalytic treatment efficiency of the wastewater.
