Description

Technical Field

[0001] This utility model belongs to the technical field of formaldehyde removal equipment, and in particular relates to the reaction chamber of a photocatalytic formaldehyde removal device. Background Technology

[0002] A photocatalytic formaldehyde removal device is a device that uses ultraviolet light to excite photocatalytic materials, such as titanium dioxide, to catalyze the degradation of harmful gases such as formaldehyde and benzene in the air.

[0003] In existing technologies, photocatalytic reaction chambers mostly adopt a simple cylindrical structure. The high-speed airflow delivered by the fan usually passes directly through the reaction chamber, resulting in a short residence time and incomplete reaction, leading to low purification efficiency. Although some models of equipment have attempted to incorporate airflow guiding structures, these are often complex, costly, and difficult to guarantee uniform ultraviolet light irradiation and sufficient airflow contact.

[0004] Therefore, there is an urgent need for a photocatalytic reaction chamber with a reasonable structure, low cost, and high reaction efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reaction chamber for a photocatalytic formaldehyde removal device. By optimizing the overall structure and key component design of the device, it can reduce airflow velocity, extend the residence time of air in the cylindrical reaction chamber, and improve photocatalytic reaction efficiency and light energy utilization.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a mounting shell and a cylindrical reaction chamber placed inside it. A cylindrical cover is installed on the top of the cylindrical reaction chamber, and a medium input pipe is installed through the cylindrical cover. A connecting seat is installed at the bottom of the mounting shell for snapping and fixing the ultraviolet lamp light source assembly. Round tubes and square tubes are fixed on both sides of the cylindrical reaction chamber and are connected to the internal chamber. An isolation component is provided inside the cylindrical reaction chamber. The connecting seat, the cylindrical reaction chamber, and the isolation component are all made of transparent plastic material.

[0007] Furthermore, the circular tube is located below the waistline of the cylindrical reaction chamber and serves as an input port, while the axis of the square tube is flush with the waistline of the cylindrical reaction chamber and serves as an output port.

[0008] Furthermore, the round tube is connected to the output end of the fan, and the square tube is connected to the air outlet of the formaldehyde removal device. The purpose of the round tube being positioned low and equipped with an isolation device is to prevent high-speed airflow from entering the cylindrical reaction chamber and flowing directly out of the square tube, thus reducing the reaction time.

[0009] Furthermore, the isolation component includes a partition, and a support ring is fixedly provided on the top and bottom of the outer side of the partition. The support ring is coaxial with the cylindrical reaction chamber, and the outer surface of the support ring is in contact with the inner side of the cylindrical reaction chamber.

[0010] Furthermore, the partition divides the cylindrical reaction chamber into two equal-volume chambers, and the two chambers are respectively connected to the round tube and the square tube. The top of the partition and the bottom of the cylindrical cover have a gap of no more than 1 / 4 of the height of the cylindrical reaction chamber for airflow transfer.

[0011] Furthermore, a fine-mesh screen made of rigid plastic filaments is bonded between the upper and lower support rings, and the fine-mesh screens are provided on both sides of the partition and respectively cover the ports of the round tube and the square tube.

[0012] Furthermore, the mounting housing has an opening for inserting the round tube and the square tube.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the reaction chamber is divided into a dual-chamber structure by an isolation component, which forces the airflow to flow along the path of bottom inlet and top outlet, reduces the air velocity, prolongs the residence time of air in the cylindrical reaction chamber, and improves the efficiency of photocatalytic reaction. 2. In this utility model, the fine mesh screen covering the ends of the round and square tubes can disperse the high-speed airflow into a uniform low-speed airflow, which is evenly distributed, avoids the generation of turbulence, and increases the contact area between the airflow and the photocatalyst. 3. In this utility model, all key components are made of transparent plastic, which reduces the obstruction of ultraviolet light transmission by the internal structure, facilitates ultraviolet irradiation of photocatalyst materials, and improves light energy utilization.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Combination Figures 1 to 4 The reaction chamber of a photocatalytic formaldehyde removal device shown includes a housing 1 and a cylindrical reaction chamber 2 placed inside it. A cover 3 is installed on the top of the cylindrical reaction chamber 2, and a medium input pipe 4 is installed through the cover 3. A connecting seat 5 is installed at the bottom of the housing 1 for locking and fixing the ultraviolet lamp light source assembly. Round tubes 21 and square tubes 22 are fixed on both sides of the cylindrical reaction chamber 2 and are connected to the internal chamber. An isolation piece 6 is provided inside the cylindrical reaction chamber 2. The connecting seat 5, the cylindrical reaction chamber 2, and the isolation piece 6 are all made of transparent plastic.

[0018] Among them, the circular tube 21 is located below the waistline of the cylindrical reaction chamber 2 and serves as the input port, while the square tube 22 has its axis aligned with the waistline of the cylindrical reaction chamber 2 and serves as the output port.

[0019] The round tube 21 is connected to the output end of the fan, and the square tube 22 is connected to the air outlet of the formaldehyde removal device. The purpose of the round tube 21 being positioned low and having an isolation component 6 is to prevent high-speed airflow from entering the cylindrical reaction chamber 2 and flowing directly out of the square tube 22, thus reducing the reaction time.

[0020] The isolation component 6 includes a partition 61. A support ring 62 is fixedly provided on the top and bottom of the outer side of the partition 61. The support ring 62 is coaxial with the cylindrical reaction chamber 2, and the outer surface of the support ring 62 is in contact with the inner side of the cylindrical reaction chamber 2.

[0021] The partition 61 divides the cylindrical reaction chamber 2 into two equal compartments, and the two compartments are connected to the round tube 21 and the square tube 22 respectively. The top of the partition 61 and the bottom of the cover 3 have a gap of no more than 1 / 4 of the height of the cylindrical reaction chamber 2 for airflow transfer.

[0022] A fine-mesh screen made of rigid plastic filaments is bonded between the upper and lower support rings 62. Fine-mesh screens are provided on both sides of the partition 61 and cover the ends of the round tube 21 and the square tube 22 respectively.

[0023] The mounting housing 1 has an opening for inserting the round tube 21 and the square tube 22.

[0024] Working principle: During use, after the device is started, the ultraviolet lamp light source component is fixed by the connecting seat 5 and emits ultraviolet light. Since the connecting seat 5, the cylindrical reaction chamber 2 and the isolation component 6 are all made of transparent material, the ultraviolet light can fully irradiate the photocatalyst material in the cylindrical reaction chamber 2 and activate it. The fan forces formaldehyde-containing air from the circular tube 21 into the left chamber of the cylindrical reaction chamber 2. After being dispersed by a fine-mesh screen, the airflow forms a uniform airflow that diffuses in the chamber on the side of the circular tube 21. Due to the obstruction of the partition 61, the airflow cannot directly enter the chamber on the side of the square tube 22. Instead, it slowly flows into the chamber on the side of the square tube 22 through the gap at the top of the partition 61. By using a detour airflow path and screen diversion, the contact time and contact opportunities between the air and the photocatalytic material are increased, and the formaldehyde gas is decomposed. After being dispersed again by the fine-mesh screen, the treated air flows into the air outlet of the formaldehyde removal device from the square tube 22, completing the formaldehyde removal cycle.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
