Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to a hydrogen peroxide catalytic remover. Background Art

[0002] Hydrogen peroxide is mainly used as a semiconductor silicon wafer cleaning agent, etchant and photoresist remover due to its strong oxidizing property. It can also be used to prepare advanced insulating layers. For example, hydrogen peroxide and acid are added to ultrapure water to etch metals, and the discharged water is slightly polluted. The current method of eliminating hydrogen peroxide is to add enzyme reagents to the front collection tank to remove hydrogen peroxide from the incoming water. Enzymes, as initiators, will not be consumed by themselves. Enzymes are organic substances. Large amounts of addition will produce bacteria and affect the long-term stable operation of reverse osmosis membranes. Small amounts of addition will not completely eliminate hydrogen peroxide. Hydrogen peroxide is an oxidant and will affect the safe operation of organic reverse osmosis. Therefore, a hydrogen peroxide catalytic remover is developed to fix the catalyst in the remover so that the catalyst does not need to be added to the water every moment, and liquid water can pass freely, which can make the catalytic removal of hydrogen peroxide more convenient. Utility Model Content

Through the utility model, the catalyst is fixed in the remover, so that the catalyst does not need to be added to the water every moment, and liquid water can pass freely, making the catalytic removal of hydrogen peroxide more convenient.

[0004] The technical solution provided by the utility model is as follows:

[0005] A hydrogen peroxide catalytic remover, comprising:

[0006] A cylinder, wherein a partition is arranged in the middle of the cylinder, the partition is fixedly connected to the inner wall of the cylinder through a fixing member, and a gap is arranged between the outer periphery of the partition and the inner wall of the cylinder;

[0007] A tubular lower filter screen is fixedly disposed between the partition plate and the bottom wall of the cylinder, wherein the bottom wall is provided with a water inlet, and the water inlet is connected to the space in the lower filter screen;

[0008] And a tubular upper filter screen is fixedly arranged between the partition plate and the top wall of the cylinder, the top wall is provided with a water outlet, the water outlet is connected to the space in the upper filter screen, and the catalyst can be filled in the upper filter screen.

[0009] Based on the above technical solution, the catalyst can be fixed through the upper filter, and the upper filter allows wastewater to pass through. The wastewater flows through the catalyst, and the hydrogen peroxide therein is catalytically decomposed. When the wastewater flows through, the catalyst will not be carried away by the wastewater and will be fixed in the upper filter.

[0010] Specifically, the partition includes:

[0011] Circular plate part;

[0012] and an annular plate portion arranged around the circumference of the circular plate portion, wherein the circular plate portion is located in the middle of the annular plate portion, and a plurality of fixing members are arranged around the circumference of the annular plate portion.

[0013] Based on the above technical solution, the circular plate portion can provide support for the lower filter screen and the upper filter screen. The annular plate portion can prevent liquid leakage at the ends of the lower filter screen and the upper filter screen, and is convenient for setting the fixing parts.

[0014] Specifically, the upper end surface of the upper filter is fixedly connected to the top wall of the cylinder, and the lower end surface of the upper filter is crimped and fixed to the edge of the upper end surface of the circular plate portion.

[0015] Furthermore, the outer periphery of the lower end of the upper filter screen is in contact with the inner wall of the upper portion of the annular plate portion.

[0016] Based on the above technical solution, liquid leakage at the upper end and the lower end of the upper filter can be better avoided.

[0017] Specifically, the lower end surface of the lower filter is fixedly connected to the bottom wall of the cylinder, and the upper end surface of the lower filter is crimped and fixed to the edge of the lower end surface of the circular plate portion.

[0018] Furthermore, based on the above technical solution, the outer periphery of the upper end of the lower filter screen fits with the inner wall of the lower part of the annular plate portion, which can better avoid leakage from the upper and lower ends of the lower filter screen.

[0019] Furthermore, the cylinder body includes an upper cylinder portion and a lower cylinder portion, the upper cylinder portion and the lower cylinder portion are detachably connected, and the partition is fixedly connected to the inner wall of the lower cylinder portion via a fixing member.

[0020] Based on the above technical solution, the upper cylinder part and the lower cylinder part are separated, and the upper filter screen and the partition plate can be conveniently separated, thereby facilitating the filling or replacement of the catalyst.

[0021] Preferably, the upper cylinder portion and the lower cylinder portion are cylinders with equal inner diameters, and the upper cylinder portion and the lower cylinder portion are threadedly connected.

[0022] Based on the above technical solution, the upper cylinder part and the lower cylinder part can be conveniently installed together, and can also be conveniently disassembled.

[0023] Beneficial effects of the utility model:

[0024] The utility model limits and fixes the catalyst, which is equivalent to less catalyst loss and no need to continuously add it to the incoming water. At the same time, since the catalyst does not lose, the organic matter in the incoming water is almost not increased, and the incoming water has no carbon source or little carbon source, so less bacteria are produced, and the corresponding non-oxygen bactericide addition is also less; adopting this technology can greatly reduce the amount of catalyst replenishment.
