Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, specifically relating to an acid receiving tray for acid zones. Background Technology

[0002] In chemical production, acid mist is generated when acid is used. To deal with acid mist, the industry generally adopts the method of connecting acid mist pipelines to the acid mist pipeline outlet of the acid tank, thereby guiding and treating the acid mist.

[0003] However, this existing technology has obvious drawbacks: during the production process, when acid mist flows through the suction pipe wall, acid condensate will form on the pipe wall due to factors such as temperature changes. Since there is no special collection structure for the docking plate, this condensate will flow directly down the pipe wall onto the operating platform below. Acid is highly corrosive, and over time, this will continuously corrode the platform, leading to structural damage and a shortened service life. More seriously, the dripping acid may come into contact with operators, causing chemical burns and other injuries, posing a significant safety hazard. At the same time, the failure to recover this acid-containing condensate also results in a waste of resources. Utility Model Content

[0004] The purpose of this invention is to provide an acid receiving plate for the acid zone, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an acid receiving tray for acid zones, comprising:

[0006] The suction duct has an annular sealing cylinder connected to its top and a connecting pipe inside the annular sealing cylinder. A sealing groove is provided between the annular sealing cylinder and the connecting pipe. Water can be injected into the sealing groove to form a water seal layer, thereby sealing the area where the connecting pipe and the acid mist duct are connected.

[0007] The acid receiving tray is fitted onto the suction duct, and the acid receiving tray and the suction duct are fitted together by PP hot-melt welding. The acid receiving tray is tilted to one side and has a drain port at the tilted end. The drain port extends into the acid tank. The acid mist condensate that falls into the acid receiving tray and the clean water in the sealed tank can be diagonally drained into the acid tank through the drain port for recycling.

[0008] Preferably, the bottom side of the annular sealing cylinder is provided with a drainage groove and the drainage groove is provided with internal threads. A threaded plug is sealed in the drainage groove and the surface of the threaded plug is provided with external threads.

[0009] Preferably, the plug is threadedly connected to the internal thread groove in the drain groove via an external thread, and a sealing gasket is provided at the threaded connection between the plug and the drain groove.

[0010] Preferably, the top of the sealing groove is provided with a sealing cover and the middle of the sealing cover body is reserved with a through hole for the acid mist pipe to pass through.

[0011] Preferably, the annular sealing cylinder, connecting pipe, plug, and sealing cap are all made of polytetrafluoroethylene.

[0012] Preferably, the acid receiving tray is welded from PPH sheet material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The sealing groove between the annular sealing cylinder and the connecting pipe forms a water seal layer by injecting clean water. It can block the acid mist leakage path by relying on the sealing property of water, effectively preventing acid mist from spreading to the workshop environment and ensuring that the workshop air quality meets environmental protection requirements. At the same time, the annular sealing cylinder, connecting pipe, plug, and sealing cover are all made of polytetrafluoroethylene, which has strong acid corrosion resistance and can maintain the stability of the sealing structure for a long time, avoiding the sealing failure problem caused by corrosion of traditional metal parts.

[0015] (2) The acid receiving tray is made of PPH plate and has good overall sealing. The inclined design, combined with the drainage port, can fully collect acid mist condensate and acidic wastewater discharged when cleaning the sealing tank. The acid receiving tray can prevent acid from dripping onto the operating platform, reduce the corrosion of the platform, and eliminate the risk of acid contact with operators, thus improving the safety of workshop operation.

[0016] (3) The acidic condensate collected by the acid receiving pan and the acidic wastewater discharged from the sealing tank can be discharged into the acid tank through the drain port for recycling, realizing the recycling of acid resources, reducing resource waste, and reducing the impact of acidic wastewater discharge on the environment, thus taking into account both economic and environmental benefits.

[0017] (4) The drainage groove at the bottom of the sealing groove is connected to the plug by a thread. The sealing gasket ensures a seal. The wastewater can be discharged easily by unscrewing the plug. The operation is simple and reduces the difficulty of equipment maintenance. Attached Figure Description

[0022] 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.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] This utility model provides, for example Figure 1-3 An acid-receiving tray shown includes:

[0025] The suction duct 1 has an annular sealing cylinder 2 connected to its top to form a sealed space. The annular sealing cylinder 2 has a connecting pipe 3 for connecting to the acid mist duct 6. An annular sealing groove 4 is provided between the annular sealing cylinder 2 and the connecting pipe 3. The sealing groove 4 is 29cm wide and 10cm deep. The sealing groove 4 can form a water seal layer around the connecting pipe 3 by injecting clean water, so as to block the path of acid mist leakage from the connection gap between the connecting pipe 3 and the acid mist duct 6, and realize the dynamic sealing of the connection area.

[0026] The acid receiving tray 5 is fitted onto the suction pipe 1 and formed a leak-proof connection by PP hot-melt welding. The acid receiving tray 5 is tilted to one side (tilt angle of 15°) to guide the fluid flow in a directional manner by gravity. The tilted end is provided with a drainage port 7 for centralized drainage. The drainage port 7 extends into the acid tank for collection, so that the acid mist condensate falling into the acid receiving tray 5 and the water discharged from the sealed tank 4 can be guided in a directional manner through the drainage port 7 to the acid tank for recycling.

[0027] The bottom side of the annular sealing cylinder 2 is provided with a drainage groove 8 for discharging water from the sealing groove 4. The drainage groove 8 is provided with internal threads to achieve a detachable sealing connection. The drainage groove 8 is sealed with a plug 9 for controlling the opening and closing of the drainage channel. The surface of the plug 9 is provided with external threads 10 that match the internal threads of the drainage groove 8.

[0028] The plug 9 forms a threaded seal connection with the internal thread groove in the drainage groove 8 through the external thread 10. The threaded connection between the plug 9 and the drainage groove 8 is provided with a sealing gasket 11 to enhance the sealing performance and prevent water in the sealing groove 4 from leaking through the thread gap.

[0029] The top of the sealing groove 4 is provided with a sealing cover 12 for sealing the groove opening. The sealing cover 12 has a through hole 13 in the middle for the acid mist pipe 6 to pass through. The through hole 13 is fitted with the acid mist pipe 6 with a clearance to ensure the pipe's passability while reducing the entry of debris into the sealing groove 4.

[0030] The annular sealing cylinder 2, connecting pipe 3, plug 9, sealing gasket 11, and sealing cap 12 are all made of polytetrafluoroethylene to resist acidic media corrosion and maintain long-term structural stability.

[0031] The acid receiving tray 5 is made of PPH sheet metal and is welded to form an integral structure with a width of 50cm, a length of 55cm and a height of 10cm, to ensure its corrosion resistance and structural sealing in acidic environments.

[0032] The acid zone is connected to the acid tray. The inner wall of the annular sealing cylinder 2 and the outer wall of the connecting pipe 3 are concentrically nested. The annular space reserved between them forms the sealing groove 4. During installation, one end of the acid mist pipe 6 is first passed through the through hole 13 in the middle of the sealing cover 12 and inserted into the sealing groove 4. At this time, the acid mist pipe 6 is fitted on the outside of the connecting pipe 3, so that the acid mist pipe 6 and the connecting pipe 3 are in a docking state. Then, 8cm deep clean water is injected into the sealing groove 4 (the water level is 2cm lower than the opening of the sealing groove 4). The water will fill the sealing groove 4 evenly, forming a continuous water seal layer around the connecting pipe 3. The fluidity of the water fills any small gaps that may exist between the acid mist pipe 6 and the connecting pipe 3, completely blocking the channel for acid mist to leak out from the connection between the connecting pipe 3 and the acid mist pipe 6. The sealing cover 12 is covered on the top of the annular sealing cylinder 2. The through hole 13 in the middle provides space for the acid mist pipe 6 to pass through, and forms a complete cover on the top of the water seal layer to seal the opening of the sealing groove 4, preventing debris and dust in the workshop from falling into the sealing groove 4 and contaminating the clean water, thus affecting the water seal effect.

[0033] The suction duct 1 draws acid mist from the acid mist duct 6 using a fan. As the acid mist flows through the suction duct 1, the outer wall of the acid mist duct 6 continuously exchanges heat with the workshop air, causing the temperature of the acid mist duct 6 to drop below the condensation temperature of the water vapor in the acid mist. This causes the water vapor in the acid mist to condense into liquid water droplets on the surface of the acid mist duct 6. These droplets gradually converge into a stream and slide down the inner wall of the acid mist duct 6. The acid receiving tray 5 is connected to the outer wall of the annular sealing cylinder 2 using a PP hot-melt welding process. The sliding water droplets can all fall into the acid receiving tray 5 along the outer wall of the annular sealing cylinder 2. The bottom surface of the acid receiving tray 5 is inclined at an angle of 15°, and a drain port 7 is provided at the lower end, allowing the condensate to flow down the drain port under gravity. The inclined surface of the acid pan 5 flows naturally towards the inlet 7, preventing water accumulation in the pan. The water then flows through the inlet 7 into the acid tank on one side for recycling. Meanwhile, the clean water in the sealing tank 4 will gradually become acidified after long-term contact with the acid mist. When it needs to be replaced periodically, the plug 9 at the bottom of the annular sealing cylinder 2 can be unscrewed. The external thread 10 of the plug 9 tightly engages with the internal thread of the drainage tank 8. The acid-resistant sealing gasket 11 sandwiched in the middle can prevent leakage. After unscrewing the plug 9, the acidic wastewater will flow into the acid pan 5 along the drainage tank 8 and flow naturally towards the inlet 7. The water then flows through the inlet 7 into the acid tank on one side for recycling. It can be transported back to the production equipment as raw material to participate in the production process, forming a closed-loop resource recycling cycle.

[0034] To maintain the water seal effect, the sealing cover 12 needs to be removed periodically to observe the water level in the sealing groove 4. When the water level drops due to evaporation, clean water should be added through the top through hole 13 until the water seal layer is restored to a state that can completely cover the gap. The acidic wastewater in the sealing groove 4 needs to be discharged according to a fixed cycle. After all the wastewater is discharged, the plug 9 should be closed and clean water should be re-injected to ensure the long-term stable operation of the equipment. After the acid receiving pan 5 has been used for a period of time, acid crystals may adhere to the inner wall. A special acid-resistant scraper should be used to remove the crystals, and then the inner wall of the acid receiving pan 5 should be rinsed with clean water to ensure that the drainage channel is unobstructed.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
