Description

Technical Field

[0001] This utility model relates to the field of central air conditioning technology, and more specifically, to a zoned purification integrated air valve device for central air conditioning ducts. Background Technology

[0002] With increasingly stringent requirements for indoor air quality, central air conditioning systems generally need to integrate air purification functions. In large buildings, the types of pollutants generated in different functional areas (such as office areas, restaurants, and conference rooms) often differ, with varying proportions of dust, odors, and volatile organic compounds, thus leading to diverse demands for purification technologies.

[0003] Currently, the common practice is to independently install various purification devices in the central air conditioning ducts, such as electrostatic precipitators, activated carbon filter boxes, and ultraviolet disinfection lamps. These devices are usually connected in series or simply in parallel in the ducts, which has the following obvious drawbacks: First, the system is lengthy and occupies a lot of installation space, making it particularly impractical for retrofit projects; second, regardless of the actual pollutant conditions, air often needs to flow through all purification units, resulting in high overall system air resistance and high fan energy consumption; third, different purification modules usually operate in fixed modes and cannot intelligently switch and target purification based on the type of pollutants monitored in real time (such as excessive concentrations of particulate matter or gaseous pollutants), resulting in energy waste and ineffective wear and tear on filter media; in addition, the maintenance of existing purification equipment, such as cleaning dust collection plates or replacing filter media, usually requires specialized tools and involves complex disassembly steps, making maintenance inconvenient and costly.

[0004] Therefore, there is an urgent need in this field for an integrated duct purification device that can be deeply coupled with the function of the air valve, can intelligently select the purification path according to the type of pollutant, and is compact and easy to maintain. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a zoned purification integrated air valve device for central air conditioning ducts.

[0006] To achieve the above objectives, this utility model provides a zoned purification integrated air valve device for central air conditioning ducts, including an air inlet pipe. Its innovation lies in the fact that it also includes a purification device, which includes a purification mechanism and a disassembly mechanism.

[0007] The purification unit is connected to the air inlet duct via an air valve;

[0008] The purification facilities include:

[0009] A connecting pipe, one end of which is connected to an air valve;

[0010] A flow divider shroud is connected to the other end of the connecting pipe, and a flow divider cavity is formed inside it;

[0011] Two purification pipes are arranged side by side, namely the first pipe and the second pipe. The inlet ends of the first pipe and the second pipe are respectively connected to the two outlets of the diversion hood.

[0012] Two valves are installed at the two outlets of the diversion hood to control the airflow into the corresponding purification pipes;

[0013] An electrostatic dust removal module is installed inside the first duct;

[0014] An activated carbon adsorption module is installed inside the second pipe;

[0015] A gas collection hood is detachably connected to the outlet ends of the first and second pipes via a connecting plate; the connecting plate is provided with through holes or locking holes that cooperate with the disassembly mechanism.

[0016] One air outlet duct is connected to the air collection hood;

[0017] The disassembly mechanism is located on the connecting plate and is used to enable the quick assembly and disassembly of the gas collection hood.

[0018] Furthermore, the aforementioned air valve is a circular louvered butterfly valve.

[0019] Furthermore, the aforementioned disassembly mechanism includes a fixed plate, a spring, a disc, a locking rod, a pull rod, and a connecting block;

[0020] The fixing plate is fixedly installed on the connecting plate. One end of the spring is connected to the fixing plate, and the other end is connected to the disc. The clamping rod is fixed to one side of the disc and passes through the through hole on the connecting plate. The pull rod is fixed to the other side of the disc. The connecting block is fixed to the gas collection hood and is provided with a clamping hole.

[0021] When the gas collection hood is engaged with the connecting plate, the locking rod is engaged into the locking hole of the connecting block under the action of the spring.

[0022] Furthermore, the first and second pipes mentioned above have rectangular cross-sectional shapes and are arranged horizontally side by side.

[0023] The technical effects and advantages of this utility model are as follows:

[0024] 1. Achieves precise purification and energy saving based on pollutant type: By setting up two independent purification pipelines and configuring corresponding control valves, the system can intelligently select to activate either electrostatic dust removal or activated carbon adsorption based on the real-time concentration of particulate matter or gaseous pollutants in the air. This selective operation mode avoids unnecessary wind resistance and energy consumption caused by air flowing through all purification units, achieving on-demand purification and significantly reducing system operating costs.

[0025] 2. Extremely convenient maintenance: A spring-loaded latch mechanism between the connecting plate and the gas collection hood allows for quick and easy unlocking and removal of the hood without any tools, directly exposing the purification module for cleaning or replacement. This design greatly simplifies the maintenance process and reduces maintenance time and labor costs. Attached Figure Description

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1 to 5 This utility model provides a zoned purification integrated air valve device for central air conditioning ducts.

[0033] like Figure 1 and Figure 2 As shown, the device includes an air inlet pipe 1 and a purification device connected to the air inlet pipe 1 via an air valve 201. The purification device includes a purification mechanism and a disassembly mechanism. The air valve 201 is preferably a circular louvered butterfly valve, which has good sealing performance and can effectively prevent air leakage. The outlet of the air valve 201 is connected to one end of the connecting pipe 202.

[0034] like Figure 2 and Figure 3 As shown, the other end of the connecting pipe 202 is connected to the flow divider shroud 203. A flow divider cavity is formed inside the flow divider shroud 203. The left side wall of the flow divider shroud 203 (with...) Figure 1(From a viewing angle) Two parallel outlets are provided. Two purification pipes, namely the first pipe 204 and the second pipe 205, are arranged horizontally side-by-side. The inlet ends of the first pipe 204 and the second pipe 205 are respectively connected to the two outlets of the diversion hood 203 via flanges or sealing rings, forming two independent purification channels. A valve 208 is installed at each of the two outlets of the diversion hood 203 (e.g., ...). Figure 3 (As shown). Valve 208 can be an electric butterfly valve or a pneumatic valve, which is controlled by an external control system and used to precisely open and close the corresponding purification channel.

[0035] like Figure 3 and Figure 4 As shown, an electrostatic dust removal module 209 is fixedly installed inside the first pipe 204 along the airflow direction for efficiently removing suspended particulate matter in the air, such as PM2.5 and dust. An activated carbon adsorption module 210 is filled or fixedly installed inside the second pipe 205 for adsorbing gaseous pollutants in the air, such as odors and volatile organic compounds like formaldehyde. The outlet ends of the first pipe 204 and the second pipe 205 are welded or fixedly connected to a connecting plate 213. A through-hole is opened in the central area of ​​the connecting plate 213 to collect purified air from both pipes; corresponding through-holes are opened around its edges according to the layout of the disassembly mechanism.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the fume hood 214 is a box-shaped structure with an open end on its right side. The exhaust pipe 215 is welded or flanged to the left side of the fume hood 214. The fume hood 214 is connected to the connecting plate 213 through its open end. To enable quick disassembly of the fume hood 214, a disassembly mechanism is provided on the connecting plate 213.

[0037] The specific structure of the disassembly mechanism is as follows: Figure 5 As shown, it includes a fixing plate 301, a spring 302, a disc 303, a locking rod 304, a pull rod 305, and a connecting block 306. The fixing plate 301 is fixedly installed on the outer surface of the connecting plate 213. One end of the spring 302 is connected to the fixing plate 301, and the other end is connected to the disc 303. The locking rod 304 is fixed to the side of the disc 303 facing the center of the connecting plate 213 and passes through a pre-set through hole on the connecting plate 213. The pull rod 305 is fixed to the side of the disc 303 facing away from the locking rod 304. The connecting block 306 is fixedly installed at the corresponding position on the edge of the opening end of the gas collecting hood 214, and the connecting block 306 has a locking hole that matches the locking rod 304.

[0038] When the gas collection hood 214 needs to be installed, it is aligned with the connecting plate 213 and pushed forward. At this time, the connecting block 306 on the gas collection hood 214 contacts and pushes the end of the locking rod 304, forcing the locking rod 304 and the disc 303 to compress the spring 302 outward. When the gas collection hood 214 is fully in place and the locking hole on the connecting block 306 is aligned with the locking rod 304, the restoring force of the spring 302 pushes the disc 303 and the locking rod 304 to reset, so that the end of the locking rod 304 is locked into the locking hole of the connecting block 306, thereby firmly locking the gas collection hood 214 onto the connecting plate 213.

[0039] When the gas collecting hood 214 is fully in place and the locking hole on the connecting block 306 aligns with the locking rod 304, the restoring force of the spring 302 pushes the disc 303 and the locking rod 304 back to their original positions, causing the end of the locking rod 304 to engage in the locking hole of the connecting block 306, thereby firmly locking the gas collecting hood 214 onto the connecting plate 213. Figure 5 The state shown.

[0040] Working principle:

[0041] This device is installed in the return or supply air duct of a central air conditioning system. Its operation is as follows:

[0042] 1. Path Selection and Purification: When the indoor air quality sensor detects that the particulate matter concentration exceeds the standard, the control system issues a command to close valve 208 at the inlet of the second pipe 205 and simultaneously open valve 208 at the inlet of the first pipe 204. The airflow to be treated enters from the air inlet duct 1, and after the total air volume is regulated by the air valve 201, it enters the diversion hood 203 through the connecting pipe 202. Since the second pipe 205 is closed, all the airflow enters the first pipe 204 through the open valve 208. As the airflow passes through the first pipe 204, the particulate matter in it is efficiently captured by the electrostatic dust removal module 209, completing the dust removal and purification.

[0043] 2. Collection and delivery: The clean air after electrostatic dust removal flows out from the outlet of the first pipe 204, enters the air collection chamber formed by the air collection hood 214 through the through hole in the center of the connecting plate 213, and is finally delivered to the air conditioning air supply duct through the air outlet pipe 215 and distributed to the required areas.

[0044] 3. Another purification mode: When an odor or excessive concentration of volatile organic compounds is detected, the control logic is reversed. The control system closes valve 208 of the first pipe 204 and opens valve 208 of the second pipe 205. The airflow then enters the second pipe 205, flows through the activated carbon adsorption module 210, where gaseous pollutants are adsorbed by the activated carbon. The purified air then flows into the gas collection hood 214 and the air outlet duct 215.

[0045] 4. Maintenance Operation: When it is necessary to clean the electrostatic precipitator module 209 or replace the activated carbon adsorption module 210, the maintenance personnel only need to pull all four levers 305 outwards simultaneously (e.g., Figure 5 (Unlocking direction). Pull rod 305 moves disc 303, compressing spring 302 and causing latch 304 to fully disengage from the locking hole of connecting block 306. At this point, the gas collection hood 214 is unlocked and can be easily removed backward, fully exposing the outlet ends of the first pipe 204 and the second pipe 205, as well as the internal purification module, making maintenance extremely convenient. After maintenance, pushing the gas collection hood 214 back to its original position will automatically lock it in place.

[0046] In summary, this embodiment achieves dual-path selective purification and quick disassembly and maintenance functions through an integrated structure.
