Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a catalytic oxidation reactor for wastewater treatment. Background Technology

[0002] Catalytic oxidation reactors are an advanced oxidation technology for treating recalcitrant organic wastewater. Their core principle is to activate the oxidant with a catalyst, generating highly oxidizing hydroxyl radicals that completely decompose pollutants into carbon dioxide and water. The system mainly consists of the reactor body, catalyst, and oxidant dosing and control system. Depending on the technical approach, catalytic oxidation reactors are mainly classified into several types, such as Fenton-like, photocatalytic, and wet catalytic oxidation reactors, each suitable for wastewater of different concentrations and characteristics. However, catalytic oxidation reactors still have the following drawbacks in practical use: In the production process, the catalytic oxidation reactor requires a catalytic structure to catalytically oxidize the mixture of wastewater and air. During the catalytic process, air is directly delivered into the reactor through the air inlet pipe, which results in incomplete catalysis of the wastewater during production. In the catalytic process, a light source is needed to irradiate the catalytic oxidation reactor. However, in production, the light source often only irradiates one side of the catalytic structure, leaving the other side unactivated and wasting the catalytic area. Furthermore, a longer catalytic time is required for complete catalysis, resulting in low efficiency of the catalytic process. Utility Model Content

[0003] The purpose of this invention is to provide a catalytic oxidation reactor for wastewater treatment. By setting up a fixed chamber, an exhaust plate, a conveying frame, and a fixed frame, it solves the problems of uneven oxygen supply during catalysis, which affects the stability of catalysis, and insufficient activation of the catalyst in the catalytic structure.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a catalytic oxidation reactor for wastewater treatment, comprising a fixed chamber, an exhaust plate, a conveying frame, and a fixed frame. An exhaust plate is fixed to the bottom of the fixed chamber, and a support frame is fixed to the inner wall of the fixed chamber above the exhaust plate. A conveying frame is supported at the top of the support frame. A corrugated plate, made of titanium catalyst material, is fixed to the middle of the inner wall of the conveying frame. Gas delivery holes are evenly spaced through the folded lines at the top and bottom of the corrugated plate. Several light-emitting lamps are evenly spaced on the inner wall of the conveying frame below the corrugated plate. A limiting frame is installed at the top of the conveying frame, and a fixing frame is fixed at the upper edge of the outer side of the limiting frame. The fixing frame is set at the top of the fixing chamber, which serves as the main container. An exhaust plate is installed at the bottom of the chamber for air input, and the conveying frame is supported by a support frame above. The conveying frame is equipped with a corrugated plate made of titanium catalyst material inside. Gas outlet holes are opened on the surface of the corrugated plate to facilitate the passage of gas and liquid. A light source is arranged below to provide light to activate the catalyst. The top of the conveying frame is positioned by the limiting frame and is fixed to the top of the fixing chamber by the fixing frame to form a complete reaction structure.

[0005] Furthermore, an output pipe is fixedly connected to the upper part of one side of the fixed chamber, a water supply pipe is fixedly connected to one side of the fixed chamber between the support frame and the exhaust plate, an installation frame is fixedly fixed to the upper part of the outer side of the fixed chamber, an output pipe is connected to the upper part of the fixed chamber for discharging treated wastewater, a water supply pipe is provided on the side wall for water inlet, and the top installation frame is used to fix the upper components, thereby realizing the functions of wastewater input, output and structural installation.

[0006] Furthermore, the exhaust plate is hollow inside and has exhaust holes arranged in a rectangular array on the top. An air inlet pipe is fixedly connected to one side of the exhaust plate and passes through and is fixed to one side of the fixed chamber. The exhaust plate is designed as a hollow structure with exhaust holes evenly opened on the top to disperse the air. The side is connected to the air inlet pipe that passes through to the outside of the fixed chamber, which is used to evenly introduce oxidizing air into the wastewater.

[0007] Furthermore, a drain outlet is provided on the upper part of one side of the conveying frame, and the drain outlet corresponds to the position of the output pipe. The upper part of the inner wall of the conveying frame is symmetrically fixed with hanging ears. The drain outlet on the upper part of the conveying frame corresponds to the output pipe to ensure that the wastewater is discharged smoothly. The hanging ears are symmetrically provided on the inner wall to facilitate the operation of the hoisting equipment and to facilitate the overall extraction during maintenance.

[0008] Furthermore, each of the four corners of the fixed frame is vertically connected with a fastening bolt. The fastening bolt is threadedly connected to the four corners of the mounting frame. The four corners of the fixed frame are equipped with fastening bolts that are threadedly connected to the mounting frame at the top of the fixed compartment, so as to achieve detachable fixing and facilitate subsequent maintenance or replacement of internal components.

[0009] Furthermore, a glass plate is fixed to the upper part of the fixed frame, and an installation block is embedded in one side of the glass plate. The installation block is fixed to the inner wall of the limiting frame, and an exhaust pipe is vertically fixed inside the installation block. The glass plate installed inside the fixed frame not only transmits natural light and other light sources to assist the catalytic reaction, but also fixes the exhaust pipe through the embedded installation block to discharge the gas generated during the reaction and maintain the normal operation of the system.

[0010] This utility model has the following beneficial effects: This invention solves the problem of uneven oxygen supply in catalytic oxidation reactors, which affects catalytic stability, by setting up a fixed chamber and an exhaust plate. Wastewater to be treated is transported to the fixed chamber through a water supply pipe, while air for oxidation is simultaneously transported to the exhaust plate through an air inlet pipe. The air is then delivered to the wastewater in the fixed chamber through an exhaust hole at the top of the exhaust plate. The wastewater and air bubbles rise together and pass through a corrugated plate. As the wastewater passes through the corrugated plate, it is exposed to light, and the corrugated shape increases the contact area with the wastewater. The passing air also provides oxygen, thus catalytically oxidizing the wastewater and purifying it. This results in a more uniform oxygen supply in the catalytic oxidation reactor, ensuring catalytic stability.

[0011] This invention solves the problem of insufficient catalyst activation in the catalytic structure of a catalytic oxidation reactor by setting up a fixed chamber, a conveying frame, and a fixing frame. When wastewater and air are mixed, the mixture is conveyed upwards. When the air and water come into contact with the corrugated plate, the light source emits light, and at the same time, natural light shines through the glass plate onto the top of the corrugated plate. This ensures that both the top and bottom of the corrugated plate are activated by light, which in turn activates the oxygen in the passing air and treats the organic pollutants in the wastewater. This results in more complete catalyst activation in the catalytic structure of the catalytic oxidation reactor, increasing catalytic efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-4This utility model is a catalytic oxidation reactor for wastewater treatment, including a fixed chamber 1, an exhaust plate 2, a conveying frame 3, and a fixed frame 4. The exhaust plate 2 is fixed to the bottom of the fixed chamber 1. The fixed chamber 1 contains water requiring catalytic oxidation. Air for catalytic oxidation is conveyed into the fixed chamber 1 through the exhaust plate 2. A support frame 101 is fixed to the inner wall of the fixed chamber 1 above the exhaust plate 2. The exhaust plate 2 supports the conveying frame 3 through the support frame 101. The top of the support frame 101 supports the conveying frame 3, which conveys the rising wastewater requiring catalytic oxidation. The wastewater is oxidized as it passes through the conveying frame 3. A corrugated plate 302, made of titanium catalyst material, is fixed to the middle of the inner wall of the conveying frame 3. After the corrugated plate 302 is exposed to light, it is oxidized by the passing air. The wastewater undergoes catalytic oxidation. Air inlets 303 are evenly spaced and perforated along the folded lines at the top and bottom of the corrugated plate 302. During operation, the corrugated plate 302 transports catalytically treated air and water through the air inlets 303. Several light lamps 305 are evenly spaced and fixed to the inner wall of the conveying frame 3 below the corrugated plate 302. The light lamps 305 illuminate the bottom of the corrugated plate 302, catalytically activating the bottom of the corrugated plate 302. The oxygen in the air reacts with the water to generate hydroxyl ions, which treat the wastewater. A limiting frame 401 is abutted against the top of the conveying frame 3, limiting the position of the conveying frame 3 within the fixed chamber 1. A fixing frame 4 is fixed to the upper edge of the outer side of the limiting frame 401, serving as a fixed installation for the limiting frame 401 within the fixed chamber 1. The fixing frame 4 is located at the top of the fixed chamber 1.

[0017] Specifically, an output pipe 103 is fixedly connected to the upper part of one side of the fixed chamber 1. The end of the output pipe 103 away from the fixed chamber 1 is connected to the wastewater discharge equipment. A water supply pipe 104 is fixedly connected to one side of the fixed chamber 1 between the support frame 101 and the exhaust plate 2. An installation frame 102 is fixedly fixed to the upper part of the outer side of the fixed chamber 1. The fixed chamber 1 outputs the treated wastewater through the output pipe 103. The end of the water supply pipe 104 away from the fixed chamber 1 is connected to the wastewater input pipeline. The installation frame 102 provides installation for the fixed frame 4 on the top of the fixed chamber 1.

[0018] Furthermore, the exhaust plate 2 is hollow inside and has exhaust holes 201 arranged in a rectangular array on its top, so that air can enter the wastewater to be treated evenly. An air inlet pipe 202 is fixedly connected to one side of the exhaust plate 2. The air inlet pipe 202 passes through and is fixed to one side of the fixed chamber 1. The exhaust plate 2 delivers the air entering it evenly and rises through the exhaust holes 201. The end of the air inlet pipe 202 away from the exhaust plate 2 is connected to the air delivery equipment, and delivers air to the exhaust plate 2 during operation.

[0019] The operation process of this embodiment is as follows: During the operation of the fixed chamber 1, the wastewater to be treated is transported into the fixed chamber 1 through the water supply pipe 104. At the same time, the air supply pipe 202 transports the air used for oxidation to the exhaust plate 2, and then transports it into the wastewater in the fixed chamber 1 through the exhaust hole 201 at the top of the exhaust plate 2. The wastewater and air bubbles rise together and pass through the corrugated plate 302. When the wastewater passes through the corrugated plate 302, the corrugated plate 302 is exposed to light and becomes corrugated, increasing the contact area with the wastewater. When the air passes through, it provides oxygen elements, catalyzing the oxidation of the wastewater to achieve the effect of purifying the wastewater. The wastewater and the air used for oxidation treatment pass through the air supply hole 303 on the corrugated plate 302 from below to above, and the treated wastewater is output through the output pipe 103. Specific Implementation Example 2

[0020] Please see Figure 1-6 Based on the first specific embodiment, a drain outlet 301 is provided on the upper part of one side of the conveying frame 3. The drain outlet 301 corresponds to the position of the output pipe 103. The upper part of the inner wall of the conveying frame 3 is symmetrically fixed with hanging ears 304. The conveying frame 3 outputs wastewater from the fixed chamber 1 through the drain outlet 301. After the fixed frame 4 is removed from the fixed chamber 1, it can be hung on the hanging ears 304 by the hoisting equipment and pulled upward to pull the conveying frame 3 out of the fixed chamber 1.

[0021] Specifically, each of the four corners of the fixed frame 4 is vertically connected with a fastening bolt 402. The fastening bolt 402 is threaded and connected to the four corners of the mounting frame 102. During the installation of the fixed frame 4, after it is placed on top of the fixed chamber 1, the fastening bolt 402 is inserted into the fixed frame 4, then screwed into the mounting frame 102 and tightened, and the fixed frame 4 is installed on top of the fixed chamber 1.

[0022] Furthermore, a glass plate 403 is fixed to the upper part of the fixed frame 4, and an installation block 404 is embedded and fixed to one side of the glass plate 403. The installation block 404 is fixed to the inner wall of the limiting frame 401. An exhaust pipe 405 is vertically fixed inside the installation block 404. The top of the exhaust pipe 405 is connected to the external exhaust equipment to discharge the gas catalytically oxidized in the fixed chamber 1. The fixed frame 4 transmits external light sources such as natural light through the glass plate 403 and transmits the natural light sources such as natural light to the corrugated plate 302 to produce a catalytic effect. The exhaust pipe 405 fixed to the inner wall of the glass plate 403 and the fixed frame 4 output the air catalytically oxidized in the fixed chamber 1.

[0023] The operation process of this embodiment is as follows: During operation, when sewage and air are mixed, they are conveyed upwards. When air and water come into contact with the corrugated plate 302, the light lamp 305 emits light. At the same time, the glass plate 403 shines on the top of the corrugated plate 302 through the natural light source such as external light, so that the top and bottom of the corrugated plate 302 are activated by light and the oxygen in the passing air is activated, and the organic pollutants in the sewage are treated. When it is necessary to clean the top of the exhaust plate 2 and the conveying frame 3 in the fixed chamber 1, the fastening bolt 402 is turned. After the fastening bolt 402 is unscrewed from the mounting frame 102, the fixed frame 4 is removed. Then, the lifting equipment hook can be hooked with the hanging ear 304 in the conveying frame 3 in the fixed chamber 1, and the conveying frame 3 can be pulled out of the fixed chamber 1.
