Description

Technical Field

[0001] This utility model relates to the technical field of high-efficiency descaling equipment for steam production, and particularly to high-efficiency descaling equipment for steam production. Background Technology

[0002] In the field of steam production, during the long-term operation of equipment such as boilers and heat exchangers, components such as calcium and magnesium ions in the water will gradually precipitate due to heating, forming scale on the inner wall of the equipment. The thermal conductivity of scale is much lower than that of metal, which will significantly reduce the heat exchange efficiency of the equipment, leading to increased energy consumption. At the same time, it may cause local overheating of the equipment, affecting operational safety and service life.

[0003] Existing high-efficiency descaling equipment for steam production cannot effectively remove scale from the boiler inner wall by combining acid washing with high-pressure water jet. In actual use, when relying solely on acid washing, it is difficult to completely remove hard and tightly attached scale by chemical dissolution alone, and scale layers are easily left behind. When relying solely on high-pressure water jet, the impact force on hard scale that has not been softened is limited, especially in areas with thick scale, where it is easy to not be cleaned thoroughly, resulting in repeated scale accumulation and long-term impact on boiler thermal efficiency. Therefore, we propose a high-efficiency descaling equipment for steam production. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency descaling device for steam production, in order to solve the problem mentioned in the background art that it is impossible to effectively remove scale from the inner wall of boilers by combining acid washing and high-pressure water jet. In actual use, when relying solely on acid washing, it is difficult to completely remove hard and tightly attached scale by chemical dissolution alone, and scale layers are easy to remain. When relying solely on high-pressure water jet, the impact force on hard scale that has not been softened is limited, especially in areas with thick scale, where it is easy to not be cleaned thoroughly, resulting in repeated accumulation of scale and long-term impact on boiler thermal efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency descaling device for steam production, including a support platform, a boiler mounted on top of the support platform, a drain pipe fixedly connected to the lower right side of the boiler, a descaling assembly mounted behind the boiler, the descaling assembly including a trolley and a water pump, a support plate fixedly mounted on top of the trolley, an installation groove on top of the support plate, a spray plate and an angled nozzle connected to the water pump via an output pipe, a diversion pipe connected to the water pump via an input pipe, and an acid tank and a clean water tank connected to the diversion pipe via a control valve pipe.

[0006] As a preferred embodiment, the trolley is positioned behind the boiler, the water pump is fixedly installed on the back of the support plate, one end of the output pipe is fixedly connected to the output end of the water pump, the other end of the output pipe is fixedly connected to the top of the spray plate, and the spray plate is fixedly installed on the inner wall of the mounting groove.

[0007] As a preferred embodiment, multiple sets of angled nozzles are provided, and the multiple sets of angled nozzles are circumferentially distributed and fixedly connected to the bottom of the spray plate. All sets of angled nozzles are aligned with the inner wall of the boiler. One end of the input pipe is fixedly connected to the input end of the water pump, and the other end of the input pipe is fixedly connected to the inside of the diversion pipe.

[0008] As a preferred embodiment, the control valve pipe is provided in two sets. One end of each set of control valve pipes is fixedly connected to the inside of the diversion pipe. The other end of one set of control valve pipes is fixedly connected to the inside of the acid tank, and the other end of the other set of control valve pipes is fixedly connected to the inside of the clean water tank. Both the acid tank and the clean water tank are fixedly installed on the top rear of the trolley.

[0009] As a preferred embodiment, the boiler is provided with a scraping assembly on its exterior. The scraping assembly includes a disc, a slide, and a connecting arm.

Then, through the sliding of the sliding block and the circular groove, the scraper plate can move in a circular motion on the inner wall of the boiler, performing a comprehensive scraping operation on the inner wall of the boiler. For the small amount of stubborn or loose scale that still adheres to the inner wall of the boiler after acid washing and high-pressure water jet cleaning, it can be completely removed by scraping, avoiding the re-deposition of residual scale or affecting the subsequent steam production efficiency.

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] Please see the appendix Figure 1 and appendix Figure 3 - Appendix Figure 5 The high-efficiency descaling equipment for steam production includes a support platform 1, a boiler 2 mounted on top of the support platform 1, a drain pipe 3 fixedly connected to the lower right side of the boiler 2, and a descaling component 4 mounted behind the boiler 2. The descaling component 4 includes a trolley 401 and a water pump 404. A support plate 402 is fixedly mounted on top of the trolley 401, and an installation groove 403 is opened on the top of the support plate 402. The water pump 404 is connected to a spray plate 406 and an angled spray head 407 through an output pipe 405. The water pump 404 is connected to a diversion pipe 409 through an input pipe 408. The diversion pipe 409 is connected to an acid tank 411 and a clean water tank 412 through a control valve pipe 410.

[0024] Boiler 2 is the core equipment for steam production. Multiple sets of angled nozzles 407 are aimed at the inner wall of boiler 2, spraying cleaning fluid and low-concentration acid solution onto the inner wall of boiler 2 at a certain angle to achieve all-round coverage.

[0025] The trolley 401 is positioned behind the boiler 2. The water pump 404 is fixedly installed on the back of the support plate 402. One end of the output pipe 405 is fixedly connected to the output end of the water pump 404, and the other end is fixedly connected to the top of the spray plate 406. The spray plate 406 is fixedly installed on the inner wall of the mounting groove 403. Multiple sets of angled nozzles 407 are provided, arranged circumferentially and fixedly connected to the bottom of the spray plate 406. All sets of angled nozzles 407 are aligned with the inner wall of the boiler 2. One end of the input pipe 408... One end is fixedly connected to the input end of the water pump 404, and the other end of the input pipe 408 is fixedly connected to the inside of the diversion pipe 409. There are two sets of control valve pipes 410. One end of each set of control valve pipes 410 is fixedly connected to the inside of the diversion pipe 409. The other end of one set of control valve pipes 410 is fixedly connected to the inside of the acid tank 411, and the other end of the other set of control valve pipes 410 is fixedly connected to the inside of the clean water tank 412. The acid tank 411 and the clean water tank 412 are both fixedly installed on the top rear of the trolley 401.

[0026] Both the top of the acid tank 411 and the clean water tank 412 are fixedly equipped with inlet pipes. The drain pipe 3 is located on the lower right side of the boiler 2 and is used to discharge the sewage, sediment and waste generated during the descaling process in the boiler 2. The mounting groove 403 can ensure the accurate positioning of the spray plate 406 so that the angled nozzle 407 is aligned with the inner wall of the boiler 2. The diversion pipe 409 serves as a pipeline branch node and is connected to the acid tank 411 and the clean water tank 412 respectively through two sets of control valve pipes 410, which can realize the switching of different cleaning solutions.

[0027] Specifically, through the descaling component 4, after the operator starts the water pump 404, the flow path between the acid tank 411 and the clean water tank 412 can be quickly switched through the diversion pipe 409 and two sets of control valve pipes 410, realizing an integrated process of acid washing pretreatment and clean water rinsing. This process can soften stubborn scale and prevent residual acid from corroding the equipment. The combination of acid washing and high-pressure water jet is gentler than simple mechanical scraping and can avoid damaging the inner wall of the boiler 2. The multiple sets of angled nozzles 407 distributed around the bottom of the spray plate 406 ensure that acid and clean water are sprayed onto the inner wall of the boiler 2 at multiple angles, eliminating cleaning dead corners and improving descaling efficiency.

[0028] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 6 and appendix Figure 7 The boiler 2 is equipped with a scraping assembly 5 on its exterior. The scraping assembly 5 includes a disc 501, a slide 503, and a connecting arm 506. The disc 501 is fixedly installed on the outer wall of the boiler 2. A circular groove 502 is opened on the top of the disc 501. The slide 503 is slidably connected to the inside of the circular groove 502. A connecting plate 504 is fixedly connected to the top of the slide 503. A rotating hole 505 is opened on the top of the connecting plate 504. A scraper 507 is fixedly connected to one side of the bottom of the connecting arm 506. A rotating rod 508 is fixedly connected to the other side of the bottom of the connecting arm 506. The rotating rod 508 is rotatably connected to the inside of the rotating hole 505.

[0029] The length of the scraper 507 is matched with the depth of the boiler 2. Under the action of the rotating rod 508, the operator can move the scraper 507 into the interior of the boiler 2. At this time, the outer wall of the scraper 507 can fit against the inner wall of the boiler 2.

[0030] Specifically, through the scraping component 5, after the descaling work is completed, the operator can manually rotate the connecting arm 506. Under the action of the rotating rod 508, the position of the scraper 507 is adjusted. Then, through the sliding of the slide block 503 and the circular groove 502, the scraper 507 can perform a circular motion on the inner wall of the boiler 2, and perform a comprehensive scraping operation on the inner wall of the boiler 2. For the small amount of stubborn or loose scale that still adheres to the inner wall of the boiler 2 after acid washing and high-pressure water jet cleaning, it can be completely removed by scraping, so as to avoid the residual scale from being deposited again or affecting the subsequent steam production efficiency.

[0031] Working principle of this utility model: This utility model is a high-efficiency descaling device for steam production. First, the operator moves the trolley 401 to the rear of the boiler 2, ensuring that the spray plate 406 is aligned with the inlet of the boiler 2. Then, a low-concentration acid solution and clean water are injected through the inlet pipes at the top of the acid tank 411 and the clean water tank 412, respectively. Next, the operator starts the water pump 404 and opens the control valve pipe 410 connected to the acid tank 411. The acid solution enters the water pump 404 through the diversion pipe 409 and the input pipe 408, and is then transported to the spray plate 406 through the output pipe 405. Multiple sets of angled nozzles 407 spray the acid solution onto the inner wall of the boiler 2 at multiple angles, softening the hard scale. The acid washing continues for five to ten minutes to separate the scale from the metal wall. Afterward, the operator closes the control valve pipe 410 connected to the acid tank 411 and opens the control valve pipe 406 connected to the water tank 412. The control valve pipe 410 of the clean water tank 412 delivers clean water to the angled nozzle 407 via the same path. High-pressure water is used to flush the inner wall of the boiler 2, removing the softened scale. The flushing wastewater is discharged through the drain pipe 3. Then, the staff moves the trolley 401 to the side and manually lifts the scraping component 5 upwards. Then, the staff manually rotates the connecting arm 506 and adjusts the angle of the scraper 507 through the rotating rod 508. The sliding seat 503 is then placed inside the circular groove 502, and the scraper 507 is sent into the interior of the boiler 2, so that its outer wall fits against the inner wall. Then, the staff can manually push the connecting arm 506, and the sliding seat 503 will slide in the circular groove 502, causing the scraper 507 to make a circular motion, scraping off the remaining stubborn scale. The scraped debris is discharged from the drain pipe 3 with the water flow.

[0032] 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.
