Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a desulfurization tower used for non-ferrous metal smelting. Background Art

[0002] A desulfurization tower is a tower-type equipment used to desulfurize industrial waste gas. Non-ferrous metal smelting is an industrial process that involves the extraction and preparation of metals from non-ferrous metal ores, waste or other raw materials. During the smelting process, sulfur-containing gases need to be desulfurized through a desulfurization tower.

[0003] After searching, the patent number is CN218981083U, and the name is a utility model of a high-efficiency desulfurization tower, which includes a desulfurization tower, a backwash layer group, a spray layer group, a catalyst packing layer and a reflux port. Through research and analysis, it is found that although the contact area between gas and liquid is increased and the catalyst reaction time is increased, the following defects still exist to a certain extent.

[0004] For example, the above-mentioned desulfurization tower process design uses a built-in spray head in the desulfurization tower for desulfurization. This process is prone to clogging in actual applications, resulting in poor desulfurization effect. Spray heads with fine pipe diameters often become clogged, causing environmental data to exceed standards and unable to produce normally for a long time, causing great economic losses to the company. In order to solve the above technical problems, we have designed a desulfurization tower that can be used for non-ferrous metal smelting. Utility Model Content

[0005] The utility model aims to provide a desulfurization tower for non-ferrous metal smelting, which has the advantages of large water volume to avoid blockage, reduce desulfurization cost, improve desulfurization efficiency, low operating cost and failure rate, and solves the problems of easy blockage, high desulfurization cost, poor desulfurization effect, high operating cost and failure rate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a desulfurization tower for non-ferrous metal smelting, comprising a first tower body, the top of the first tower body is fixedly connected with a first connecting pipe, the right side of the first connecting pipe is fixedly connected with a second tower body, the top of the second tower body is fixedly connected with a second connecting pipe, the right side of the second connecting pipe is fixedly connected with a third tower body, the top of the third tower body is fixedly connected with a chimney, the surfaces of the first tower body, the second tower body and the third tower body are all fixedly connected with a liquid inlet pipe and a water outlet pipe, the first tower body comprises a tower body, the inner cavity of the tower body is fixedly connected with a support plate, the top of the support plate is fixedly connected with a funnel plate, the top of the funnel plate is fixedly connected with an umbrella plate, the bottoms of the first tower body, the second tower body and the third tower body are fixedly connected with a desulfurization tower liquid pool, and the inner cavity of the liquid inlet pipe is penetrated and inserted with a delivery pipe.

[0007] Preferably, an air inlet pipe is fixedly connected to the bottom of the left side of the first tower body, and the structures of the first tower body, the second tower body and the third tower body are the same.

[0008] Preferably, maintenance racks are provided on the outer sides of the first tower body, the second tower body and the third tower body, and an inspection rack is fixedly connected to the right side of the top of the maintenance rack.

[0009] Preferably, a first climbing ladder is fixedly connected to the left side of the front side of the maintenance rack, and a second climbing ladder is fixedly connected between the top of the maintenance rack and the inspection rack.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. Lime slurry flows into the first tower body from the delivery pipe, and splashes to the pipe wall after passing through the umbrella-shaped plate to form a water curtain. The sulfur-containing gas passes through the water curtain and fully contacts with the desulfurization liquid. After the water curtain falls to the bottom, it is gathered to the center through a set of funnel plates and then falls to the next umbrella-shaped plate through repeated cycles and so on. It contacts with the sulfur-containing gas many times, and the water and gas contact is more complete, which improves the desulfurization effect. Multiple delivery pipes are installed in each tower body to increase the liquid intake. A larger amount of water can avoid blockage.

[0012] 2. The desulfurized gas in the first tower body enters the second tower body through the first connecting pipe for re-desulfurization, and enters the third tower body through the second connecting pipe for tertiary desulfurization. This makes the desulfurization more thorough. The use of lime slurry can reduce the desulfurization cost. The clean water can be recycled after the liquid is precipitated, meeting the requirements of long-term production process and reducing operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the chimney 10, desulfurization can be facilitated The gas after the desulfurization is discharged from the third tower body 3. The first tower body 1 includes a tower body 15. The inner cavity of the tower body 15 is fixedly connected with a support plate 16. The top of the support plate 16 is fixedly connected with a funnel plate 13. The top of the funnel plate 13 is fixedly connected with an umbrella-shaped plate 14. The support plate 16 has a supporting and positioning function, and can conveniently fix the funnel plate 13 and the umbrella-shaped plate 14. The bottoms of the first tower body 1, the second tower body 2 and the third tower body 3 are fixedly connected with a desulfurization tower liquid pool 19. The inner cavity of the liquid inlet pipe 12 is penetrated and plugged with a delivery pipe 18;

[0021] See also Figure 1 The bottom of the left side of the first tower body 1 is fixedly connected with an air intake pipe 6, and the structures of the first tower body 1, the second tower body 2 and the third tower body 3 are the same;

[0022] See also Figure 1 A maintenance frame 7 is provided on the outside of the first tower body 1, the second tower body 2 and the third tower body 3, and an inspection frame 11 is fixedly connected to the right side of the top of the maintenance frame 7. By providing the maintenance frame 7 and the inspection frame 11, it is convenient for personnel to inspect and maintain the entire desulfurization tower;

[0023] See also Figure 1 A first climbing ladder 4 is fixedly connected to the left side of the front side of the maintenance frame 7, and a second climbing ladder 17 is fixedly connected between the top of the maintenance frame 7 and the inspection frame 11.

[0024] When in use, the sulfur-containing gas enters the first tower body 1 through the air inlet pipe 6 and flows from bottom to top in the first tower body 1. At this time, the lime slurry flows into the first tower body 1 from the delivery pipe 18. The water flows through the umbrella plate 14 and splashes to the pipe wall to form a water curtain. The sulfur-containing gas passes through the water curtain and fully contacts with the desulfurization liquid to achieve the desulfurization effect. After the water curtain falls to the bottom, it is gathered to the center position by a set of funnel plates 13 and then falls to the next umbrella plate 14 through repeated cycles. In this way, the water and gas contact more fully and the desulfurization effect is improved. Since each tower body 15 is installed There are multiple conveying pipes 18, which can increase the liquid intake, and a larger water volume can avoid blockage. The desulfurized gas in the first tower body 1 enters the second tower body 2 through the first connecting pipe 8 for re-desulfurization, and finally enters the third tower body 3 through the second connecting pipe 9 for three desulfurization. In this way, the separation is more thorough, and the use of lime slurry can reduce the desulfurization cost. At the same time, the sulfur-containing and white lime liquid removed can be recycled after precipitation through the desulfurization tower liquid pool 19. The lime slag is separated into solid and liquid after passing through the plate and frame filter press, which meets the requirements of long-term production process and reduces operating costs.
