Description

Technical Field

[0001] This utility model relates to the field of gas treatment equipment technology, and in particular to a novel and practical three-dimensional spray adsorption device. Background Technology

[0002] Currently, using spray towers to treat toxic and harmful gases is a mature technology in industrial environmental governance. Its core principle lies in atomizing water or specific chemical absorbents through nozzles, allowing them to fully contact the polluted gases flowing in counter-current or cross-current directions within the tower. During this process, soluble or reactive pollutants in the gas (such as acidic gases and dust particles) are captured, absorbed, or chemically reacted by the droplets, thereby achieving the purification goal.

[0003] However, this technology has revealed a significant drawback in actual operation: during the recycling process, the spray liquid continuously accumulates pollutants and potentially introduced solid particles, which can easily lead to blockages in the delivery pipelines and nozzles. In particular, precision components such as filter components and nozzles are prone to blockages. Once blocked, not only will the uniformity of spraying and purification efficiency be greatly reduced, but abnormal system pressure will also be caused, threatening equipment safety. Currently, the main way to deal with blockages is to disassemble, manually clean, or replace the filter components and pipelines after shutdown. This process is time-consuming and labor-intensive, resulting in long downtime of the entire purification system and seriously affecting the continuity of production.

[0004] Therefore, while ensuring the purification effect, how to effectively solve the persistent problem of easy clogging of the spray system and minimize downtime caused by maintenance work has become a key technical issue that urgently needs to be optimized and improved in this field. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a new practical three-dimensional spray adsorption device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides a novel and practical three-dimensional spray adsorption device, comprising: A container with an internal chamber for handling gases; A spray assembly, disposed within the chamber, is used to spray purifying liquid into the gas within the chamber; A liquid system for providing purification liquid to the spray assembly, the liquid system including a delivery pipeline and a filter assembly, the delivery pipeline for guiding the purification liquid to flow sequentially through the filter assembly and the spray assembly along a first flow direction; A backwashing system includes a backwashing pipeline and a flow direction switching structure. The flow direction switching structure is used to selectively connect the filter assembly to either the delivery pipeline or the backwashing pipeline. When switched to the backwashing pipeline, the purified liquid flows through the filter assembly in a second flow direction opposite to the first flow direction to backwash the filter assembly and discharge the rinsed impurities through a drain passage.

[0007] As a preferred embodiment of the present invention, the conveying pipeline includes a first connecting pipe, a second connecting pipe, a third connecting pipe and a spray main pipe connected in sequence. The spray main pipe is connected to the spray assembly at its end away from the third connecting pipe, and the filter assembly is disposed between the second connecting pipe and the third connecting pipe.

[0008] As a preferred embodiment of this utility model, the backwashing pipeline includes a fourth connecting pipe and a fifth connecting pipe, and the flow direction switching structure includes a first regulating valve, a second regulating valve, and a third regulating valve. The first regulating valve has three connecting ends. The second connecting pipe and the first connecting pipe are connected to two of the connecting ends of the first regulating valve. One end of the fourth connecting pipe is connected to the third connecting end of the first regulating valve, and the other end of the fourth connecting pipe is connected to the third connecting pipe. The second connecting pipe and the fifth connecting pipe are connected through the third regulating valve to form a sewage discharge passage.

[0009] As a preferred embodiment of this utility model, the first regulating valve is a three-way ball valve, which switches between the delivery pipeline and the backwashing pipeline by rotating the valve core.

[0010] As a preferred technical solution of this utility model, the device further includes a control unit for controlling the flow direction switching structure. The control unit controls the flow direction switching structure to switch from the delivery pipeline to the backwash pipeline based on the pressure difference signal between the upstream and downstream of the filter component, and controls it to switch back to the delivery pipeline after a preset backwash time.

[0011] As a preferred embodiment of this utility model, the main spray pipe passes through a wall groove formed on the surface of the container and extends into the container.

[0012] As a preferred embodiment of this utility model, the spray assembly includes: A multi-port fitting has one main port and multiple secondary ports, wherein the main port is connected to a delivery pipeline; A spray branch pipe, one end of which is connected to the secondary interface, and the spray branch pipe forms multiple connecting tail pipes on the side of the gas inflow direction, and the connecting tail pipes are arranged at intervals along the length direction of the spray branch pipe. The nozzle is connected to the connecting tailpipe.

[0013] As a preferred embodiment of this utility model, the spray branch pipe is threadedly connected to the secondary interface, and the nozzle is threadedly connected to the connecting tail pipe.

[0014] As a preferred embodiment of this utility model, the spray assembly further includes a sealing ring with a locking protrusion, and the secondary interface has a locking groove on its end face. The locking groove engages with the locking protrusion, and the spray branch pipe is tightened to press the sealing ring against the end face of the secondary interface.

[0015] As a preferred embodiment of this invention, the filtering component includes: The filter element has a circumferential positioning plate on its outer side; The first flange is located at the end of the third connecting pipe away from the main sprinkler pipe; The second flange is located at one end of the second connecting pipe near the third connecting pipe. The inner sides of the first and second flanges are provided with positioning grooves that match the positioning plate, and the surfaces of the first and second flanges are provided with positioning holes. Bolts and their matching nuts, the bolts being adapted to locating holes.

[0016] The beneficial effects of this invention are as follows: By setting up a backwashing system including a backwashing pipeline and a flow direction switching structure, this invention achieves online cleaning of the filter components and rapid switching of operating modes. Under normal filtration conditions, the flow direction switching structure guides the purified liquid to flow through the filter components in the first direction before spraying. When cleaning is required, switching this structure causes the purified liquid to flow through the filter components in the opposite direction, achieving reverse rinsing and discharging impurities through the drain passage. Cleaning can be completed without disassembling parts, effectively solving the problems of frequent downtime and cumbersome maintenance caused by blockages, and significantly improving the continuous operating efficiency and ease of operation of the equipment.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figure 1As shown, a novel and practical three-dimensional spray adsorption device includes: a container 1, which has a chamber for treating gas inside; a spray assembly disposed in the chamber for spraying purification liquid into the gas in the chamber; a liquid path system for supplying purification liquid to the spray assembly, the liquid path system including a delivery pipeline and a filter assembly, the delivery pipeline for guiding the purification liquid to flow sequentially through the filter assembly and the spray assembly along a first flow direction; and a backwashing system including a backwashing pipeline and a flow direction switching structure, the flow direction switching structure for selectively connecting the filter assembly to the delivery pipeline or the backwashing pipeline, when switching to the backwashing pipeline, the purification liquid flows through the filter assembly along a second flow direction opposite to the first flow direction to backwash the filter assembly, and the impurities after backwashing are discharged through a drain passage. The above technical solution solves the problem of long system downtime and heavy maintenance caused by the need to completely disassemble filter components from the pipeline for cleaning due to impurities clogging them. Specifically, its working principle is as follows: the flow direction switching structure changes the direction of the liquid flowing through the filter component, realizing rapid switching of the filtration mode. In use, the operation steps are as follows: during normal purification, the flow direction switching structure causes the purified liquid to flow forward along the first flow direction through the filter component and then spray it; when cleaning the filter component is required, the gas purification process can be briefly stopped or switched to a standby purification unit. Then, the flow direction switching structure is operated to connect it to the backwash pipeline, causing the purified liquid to backwash the filter component along the second flow direction, i.e., in reverse, carrying impurities out through the drain passage. This achieves rapid online cleaning of the filter component, greatly shortening the downtime required for system maintenance, simplifying maintenance operations, and ensuring the overall operating efficiency of the device.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, the delivery pipeline includes a first connecting pipe 21, a second connecting pipe 9, a third connecting pipe 8 and a spray main pipe 3 connected in sequence. The spray main pipe 3 is connected to the spray assembly at its end away from the third connecting pipe 8, and the filter assembly is disposed between the second connecting pipe 9 and the third connecting pipe 8. The above technical solution can solve the problems that unclear pipeline connections and unreasonable filter component installation positions may affect the filtration effect and system pressure. Specifically, its working principle is as follows: First, determine the specific path of the purified liquid from the water source through each level of connecting pipes to the spray assembly, and then place the filter assembly in the pressurized pipeline section. In use, the operating steps are as follows: The water pump sequentially passes the purified liquid through the first connecting pipe 21, the second connecting pipe 9, and after filtration by the filter assembly, it is then delivered to the spray assembly through the third connecting pipe 8 and the main spray pipe 3. This forms a clear, efficient, low-resistance flow path, ensuring spray pressure and facilitating the maintenance of the filter assembly.

[0024] like Figure 1 and Figure 4As shown, in this embodiment, the backwashing pipeline includes a fourth connecting pipe 22 and a fifth connecting pipe 23. The flow direction switching structure includes a first regulating valve 24, a second regulating valve 25, and a third regulating valve 26. The first regulating valve 24 has three connecting ends. The second connecting pipe 9 and the first connecting pipe 21 are connected to two of the connecting ends of the first regulating valve 24. One end of the fourth connecting pipe 22 is connected to the third connecting end of the first regulating valve 24, and the other end of the fourth connecting pipe 22 is connected to the third connecting pipe 8. The second connecting pipe 9 and the fifth connecting pipe 23 are connected through the third regulating valve 26 to form a sewage discharge passage. The above technical solution enables backwashing. Specifically, its working principle is to reconstruct the flow path using combinations of opening and closing multiple valves. During operation, the steps are as follows: Under normal conditions, the first regulating valve 24 connects the first connecting pipe 21 and the second connecting pipe 9; the second regulating valve 25 is open; and the third regulating valve 26 is closed. During backwashing, the first regulating valve 24 switches to connect the first connecting pipe 21 and the fourth connecting pipe 22, while simultaneously closing the second regulating valve 25 and opening the third regulating valve 26. The purified liquid then flows backward from the first connecting pipe 21 through the fourth connecting pipe 22 into the third connecting pipe 8. After backwashing the filter assembly, the waste liquid is discharged through the second connecting pipe 9 and the fifth connecting pipe 23. This is a reliable, low-cost flow path switching solution with high flexibility.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, the first regulating valve 24 is a three-way ball valve, which switches between the delivery pipeline and the backwash pipeline by rotating the valve core; The above technical solution enables rapid and synchronous switching of flow paths. Specifically, its working principle is as follows: by rotating the valve core of the three-way ball valve, the connection relationship of its internal flow channels is directly changed. In use, the operation steps are: rotating the valve core 90 degrees allows for rapid switching between the normal operating flow path and the backwashing flow path. The system operates smoothly and has high reliability.

[0026] Furthermore, in this embodiment, the device also includes a control unit for controlling the flow direction switching structure. The control unit controls the flow direction switching structure to switch from the delivery pipeline to the backwash pipeline based on the pressure difference signal between the upstream and downstream of the filter component, and controls it to switch back to the delivery pipeline after a preset backwash time. The above technical solution solves the problems of needing to manually check at regular intervals or rely on experience to determine when to clean, as well as the low efficiency and untimely nature of manual operation. Specifically, its working principle is as follows: sensors monitor the pressure difference upstream and downstream of the filter component. When the pressure difference exceeds a set value, it indicates severe blockage, and the control unit automatically triggers the backwashing program. In use, the operation steps are as follows: the system operates fully automatically, the control unit controls the flow direction switching structure according to preset logic, and automatically restores the purification state after backwashing is completed. This achieves real-time monitoring of the filtration status and automation of the entire cleaning process, improves the intelligence level of the equipment, ensures optimal cleaning timing, and further reduces labor costs.

[0027] like Figure 1 As shown, in this embodiment, the spray pipe 3 passes through the wall groove 2 opened on the surface of the container 1 and extends into the container 1; The above technical solution solves the problems of consuming limited internal space of container 1 due to the built-in installation of equipment such as water pumps, potentially obstructing airflow, affecting purification efficiency, and facilitating maintenance. Specifically, its working principle is as follows: through the wall groove 2 structure, the driving equipment of the spray main pipe 3, such as the water pump and its main auxiliary components, is placed outside the container 1, so that the pipeline connection and layout are all completed externally. During use, the operating steps are as follows: during installation, the spray main pipe 3, which is already connected to the external water pump, is directly inserted into the container 1 through the wall groove 2 and connected and fixed to the internal spray assembly. This maximizes the effective space inside container 1, provides an unobstructed flow channel for toxic and harmful gases, improves gas-liquid contact efficiency, and greatly facilitates the installation, inspection, and maintenance of external equipment.

[0028] like Figure 1 As shown, in this embodiment, the spray assembly includes: a multi-port fitting 4, which has a main interface and multiple secondary interfaces, the main interface being connected to the delivery pipeline; a spray branch pipe 5, one end of which is connected to the secondary interface, the spray branch pipe 5 forming multiple connecting tail pipes 6 on the side of the gas direction, the connecting tail pipes 6 being arranged at intervals along the length of the spray branch pipe 5; and a nozzle 7 connected to the connecting tail pipes 6. The above technical solution solves the problems of limited coverage and poor spray uniformity of a single spray pipe. Specifically, its working principle is as follows: the purified liquid is distributed to each spray branch pipe 5 through the multi-port fitting 4, and then evenly sprayed out from the nozzle 7 through the connecting tail pipe 6. In use, the operating steps are as follows: according to the required gas volume, install different numbers of spray branch pipes 5 onto the secondary interfaces of the multi-port fitting 4. This forms an expandable three-dimensional spray network, greatly improving the contact area and uniformity between the purified liquid and harmful gases, and enhancing purification efficiency.

[0029] like Figure 2 As shown, in this embodiment, the spray branch pipe 5 is threadedly connected to the secondary interface, and the nozzle 7 is threadedly connected to the connecting tail pipe 6. The above technical solution solves the problems of complex component connections and inconvenience in replacing nozzles or cleaning branch pipes. Specifically, its working principle is to use the engagement of threads to achieve component fastening and sealing. During use, the operation steps are: simply rotate the spray branch pipe or nozzle to complete installation or disassembly. This achieves rapid assembly and disassembly, greatly facilitating the daily maintenance, cleaning, and component replacement of the spray system.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the spray assembly also includes a sealing ring 19 with a locking protrusion 20. The secondary interface has a locking groove 18 on its end face. The locking groove 18 engages with the locking protrusion 20. By tightening the spray branch pipe 5, it is pressed against the sealing ring 19 at the end face of the secondary interface. The above technical solution can solve the problem of easy loosening and leakage under vibration environment when relying solely on threaded seals. Specifically, its working principle is as follows: During installation, the engaging protrusion 20 of the sealing ring 19 is first pre-fixed with the engaging groove 18. When the spray branch pipe 5 is tightened, the sealing ring 19 is squeezed to achieve end face sealing. This forms a dual guarantee of threaded fastening and end face sealing, significantly improving the sealing reliability and durability of the connection.

[0031] like Figure 4 and Figure 5 As shown, in this embodiment, the filter assembly includes: a filter element 16 with a circumferential positioning plate 17 on its outer side; a first flange 10 located at the end of the third connecting pipe 8 away from the main spray pipe 3; a second flange 11 located at the end of the second connecting pipe 9 near the third connecting pipe 8; positioning grooves 15 that match the positioning plate 17 are provided on the inner sides of the first flange 10 and the second flange 11; positioning holes 12 are provided on the surfaces of the first flange 10 and the second flange 11; bolts 13 and their matching nuts 14, with the bolts 13 matching the positioning holes 12. The above technical solution solves the problems of inaccurate installation and positioning, poor sealing, and cumbersome replacement of filter element 16. Specifically, its working principle is as follows: the filter element 16 is precisely positioned and clamped using flange docking and positioning groove 15. In use, the operating steps are as follows: when replacing filter element 16, simply loosen bolt 13, separate the first flange 10 and the second flange 11, remove the old filter element 16, insert the new filter element 16, ensure its positioning plate 17 is engaged in the positioning groove 15, and then retighten the flange. This achieves rapid and accurate positioning and replacement of filter element 16.
