Description

Technical Field

[0001] The present invention relates to the technical field of water circulation systems, and in particular to a demisting type water collection system. Background Art

[0002] For existing demisters, in order to keep the demister blades clean, it is necessary to set up flushing water pipes and nozzles to flush the demister blades. Process water is used as the flushing water, and the sewage after flushing falls downward by gravity into the lower component, and finally falls into the slurry pool, which will increase the slurry liquid level.

[0003] For the demister, in order to avoid blockage of the blades caused by slurry retention, the higher the flushing frequency, the better. However, for the slurry pool, there are strict requirements for the slurry liquid level, so it cannot be flushed frequently. It can be seen that the requirements of the two are opposite and contradictory.

[0004] However, the existing water collectors have many problems: 1. The water collector requires a separate support beam, which increases the construction cost and difficulty on site. 2. The water collection area is small and cannot cover the area of the main beam and the sealing plate. 3. The collection capacity is low, the collection water pipe is narrow and has many bends, and it is easy to be blocked. The collected sewage cannot be discharged out of the tower in time. 4. The structure is complex, not easy to replace, and the connection parts are easy to break and fall off. 5. There is interference between the upper left corner and the upper right corner of the side plate of the tubular demister and the overall sealing plate of the demister, and secondary processing is required during installation. 6. The water collector has a single function and does not have the effects of condensation demisting and uniform distribution of flue gas. 7. There is no expandability, and it is impossible to add flushing water pipe supports, nor to increase the number of water collection layers and the demisting effect.

[0005] Therefore, it is very necessary to design a demisting type water collection system. Summary of the Invention

[0006] The purpose of the present invention is to provide a demisting type water collection system to solve the problems raised in the above background art.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-4 , the present invention provides a technical solution: a demisting type water collection system, including a demister installation frame 1, a plate demister 2, a first circulation pump 7 and a second circulation pump 8. The plate demister 2 is hung in the demister installation frame 1 and has a herringbone structure. A short hanging beam 3 is fixedly installed at the bottom of the demister installation frame 1. An end water collection assembly 5 is hung at both ends of the short hanging beam 3, and a middle water collection assembly 4 is hung at the middle short hanging beam 3. A confluence assembly 6 is fixedly installed between every two short hanging beams 3. The inner end of the end water collection assembly 5 communicates with the confluence assembly 6, and both ends of the middle water collection assembly 4 communicate with the confluence assembly 6. The confluence assembly 6 is connected to the inlet of the first circulation pump 7 through a pipeline. The outlet of the first circulation pump 7 is connected to the inlet of a water collection tank 10 through a pipeline. The outlet of the water collection tank 10 is connected to the second circulation pump 8 through a pipeline. The second circulation pump 8 is connected to a spray assembly at the top of the demister installation frame 1 through a pipeline, and the spray assembly is located above the plate demister 2.

[0031] The demister installation frame 1 is the main load-bearing structure for flue gas desulfurization and demisting. The plate demister 2 is the main functional component. Through the herringbone structure setting, the contact area is increased. The middle water collection assembly 4 and the end water collection assembly 5 are hung by the short hanging beam 3. The confluence assembly 6 integrates the water flows collected by the middle water collection assembly 4 and the end water collection assembly 5 to facilitate the extraction by the first circulation pump 7. The water collection tank 10 stores the collected water flow, and the second circulation pump 8 guides the water flow in the water collection tank 10 to the spray assembly of the demister installation frame 1 to realize the flushing of the plate demister 2.

[0032] Specifically, the middle water collection assembly 4 includes a first middle hanging plate 401 in one piece and two first end hanging plates 402. A first upper layer water collection pipe 404 and a first lower layer water collection pipe 405 are fixedly installed between the two first end hanging plates 402. The first middle hanging plate 401 is located in the middle of the first upper layer water collection pipe 404 and the first lower layer water collection pipe 405 and is inclined towards both ends based on the position of the first middle hanging plate 401.

[0033] The first upper layer water collection pipe 404 and the first lower layer water collection pipe 405 are fixedly installed through the first middle hanging plate 401 and the two second end hanging plates 501. Moreover, the first upper layer water collection pipe 404 and the first lower layer water collection pipe 405 are inclined towards both ends, so that the water flow can be better led out.

[0034] Specifically, the end water collecting assembly 5 includes two second end hanging plates 501, between which a second upper water collecting pipe 503 and a second lower water collecting pipe 504 are fixedly installed, and both the second upper water collecting pipe 503 and the second lower water collecting pipe 504 are inclined toward the inner end.

[0035] The upper water collecting pipe and the second lower water collecting pipe 504 are fixedly installed by two pieces of second end hanging plates 501, and the collected flushing water is better guided to the merging component 6 by the inward tilting setting.

[0036] Specifically, the first upper water collecting pipe 404 and the first lower water collecting pipe 405 are arranged in an alternating staggered manner, and the second upper water collecting pipe 503 and the second lower water collecting pipe 504 are arranged in an alternating staggered manner.

[0037] By staggering the arrangement of the first upper water collecting pipe 404 and the first lower water collecting pipe 405 and staggering the arrangement of the second upper water collecting pipe 503 and the second lower water collecting pipe 504, the flushing water flow can be better collected.

[0038] Specifically, the first upper water collecting pipe 404, the first lower water collecting pipe 405, the second upper water collecting pipe 503, and the second lower water collecting pipe 504 have the same structure. The first upper water collecting pipe 404 is a four-sevenths to three-fifths arc-shaped open pipe, and the open source is fixedly installed with an anti-overflow extension piece 406, and the inclination angle of the anti-overflow extension piece 406 is 30° to 40°.

[0039] By setting the opening angles of the first upper water collecting pipe 404, the first lower water collecting pipe 405, the second upper water collecting pipe 503 and the second lower water collecting pipe 504 and providing the anti-overflow extension piece 406, the extended water collecting area is increased. At the same time, the angle of the anti-overflow extension piece 406 is set so that the collected and dripping water can be better collected and discharged.

[0040] Specifically, the inclination angle of the first upper water collecting pipe 404 and the first lower water collecting pipe 405 is between 7° and 10°.

[0041] By setting the inclination angle of the first upper water collecting pipe 404 and the first lower water collecting pipe 405, the speed of water flow can be better guaranteed, while avoiding too large an angle to cause collection problems.

[0042] Specifically, the inclination angle between the second upper water collecting pipe 503 and the second lower water collecting pipe 504 is between 10° and 15°.

[0043] By setting the inclination angles of the second upper collecting water pipe 503 and the second lower collecting water pipe 504, it is possible to better ensure the water flow rate and at the same time avoid too large an angle, which may cause problems in collection.

[0044] Specifically, a first auxiliary hanging plate 403 is provided between the first middle hanging plate 401 and the first end hanging plate 402.

[0045] Through the first auxiliary hanging plate 403, the installation of the first upper collecting water pipe 404 and the first lower collecting water pipe 405 becomes more stable.

[0046] Specifically, a second auxiliary hanging plate 502 is provided between the second end hanging plates 501.

[0047] Through the second auxiliary hanging plate 502, the installation of the second upper collecting water pipe 503 and the second lower collecting water pipe 504 becomes more stable.

[0048] Working principle: During use, the second circulation pump 8 guides the water flow to the spraying component above the demister installation frame 1. The sheet demister 2 is flushed through the spraying component. After the flushing water flow passes through the sheet demister 2, it enters the middle water collecting component 4 and the end water collecting component 5 downward. After the middle water collecting component 4 and the end water collecting component 5 guide the water flow to the confluence component 6 and integrate it, the first circulation pump 7 pumps the water flow out from the confluence component 6 and guides it to the water collecting tank 10. At the same time, a filter 9 is provided between the first circulation pump 7 and the water collecting tank 10 to prevent water flow impurities from affecting the recycling.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
