Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass steel equipment, in particular to a glass steel desulfurization equipment. BACKGROUND

[0002] The equipment for desulfurization treatment of industrial waste gas is mostly tower type equipment, namely desulfurization tower.

[0003] Glass steel (FRP) is also called GFRP, namely fiber reinforced plastic, which generally refers to unsaturated polyester, epoxy resin and phenolic resin matrix reinforced by glass fiber or its products as reinforcing material. The reinforced plastic using glass fiber as reinforcing material is called glass fiber reinforced plastic, or glass steel, which is different from tempered glass. Due to the difference of the used resin varieties, there are polyester glass steel, epoxy glass steel and phenolic glass steel. It is light and hard, does not conduct electricity, has stable performance, high mechanical strength, less recycling and corrosion resistance. Therefore, with the development of glass steel technology, the desulfurization tower is gradually made of glass steel. Compared with the granite desulfurization tower, the glass steel desulfurization tower has low cost, easy processing, rust resistance and light weight, so it becomes the development trend of desulfurization tower in the future.

[0004] The present desulfurization equipment generally uses the structure of the desulfurization tower with the inner water mist multi-layer nozzle made of glass steel. The nozzle is generally made of stainless steel SUS316L to solve the high temperature liquid corrosion of SO2, and is arranged in a multi-layer annular layout in the desulfurization tower. With the entering of flue gas, the nozzle sprays mist desulfurization liquid to fully mix with the flue gas, thereby playing a desulfurization role. This desulfurization process has the problems of complicated maintenance, serious nozzle blockage due to the structure of desulfurization agent, and the need for regular cleaning. In addition, the service life of the nozzle due to corrosion is at most 2 months, and the boiler must be replaced. The stable operation life of the boiler is not more than 2 months, so the boiler needs to be stopped for maintenance. During the maintenance, the manhole is opened, and the person enters the inside of the reaction tower to check and replace the nozzle one by one, which is time-consuming and laborious. SUMMARY

[0012] The gas input by the air inlet channel needs to pass through the air hole, the third water curtain, the second water curtain, the first water curtain, the water flow hole and the demister before being output by the air outlet.

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, a detailed description is provided below in conjunction with the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] Example 1:

[0036] like Figure 1 As shown in the figure, this embodiment discloses a fiberglass desulfurization device, which includes a fiberglass-supported cylindrical tower body 1. The tower body 1 mainly serves as a load-bearing support and forms a closed space inside for industrial exhaust gas desulfurization and purification treatment.

[0037] An air inlet channel 2 is provided on one side of the tower body 1 near the lower end. The air inlet channel 2 is used to connect to external industrial exhaust gas and input the exhaust gas to be treated into the tower body 1.

[0038] It should be noted that the connection between the air inlet channel 2 and the tower body 1 is a downward path. That is, when the exhaust gas is about to enter the interior of the tower body 1 in the air inlet channel 2, it needs to move downward first. This structure can play a certain dust removal effect. Some of the particulate matter mixed in the exhaust gas will sink here and fall directly to the bottom of the inner side of the tower body 1.

[0039] The inner side of the tower body 1, above the air inlet channel 2, is provided with a desulfurization platform 3, a water hopper 6, and a demister 7, which are used for desulfurization and dehumidification of the exhaust gas.

[0040] The tower body 1 is provided with an air outlet 11 above the demister 7, the output end of the air outlet 11 is communicated with the external negative pressure pipeline, so that the inside of the tower body 1 constitutes a negative pressure state, combined with Figure 2 As shown, the three chambers separated by the desulfurization platform 3 and the water flow bucket 6 are taken as an example, due to the negative pressure of the output end of the air outlet 11, the pressure in the A area is greater than that in the B area, and the pressure in the B area is greater than that in the C area, therefore, the tail gas can naturally move upwards to the output end from bottom to top.

[0041] The bottom of the tower body 1 is provided with a drain 12 for draining the accumulated water on the inside bottom of the tower body 1.

[0042] Specifically, combined with Figure 3 The water flow bucket 6 is provided with a water flow pipeline 61 and a water flow hole 62 on the upper and lower sides respectively, the water flow pipeline 61 is communicated with the external pipeline, and can deliver liquid medicine to the water flow bucket 6, the liquid medicine falls uniformly through the water flow hole 62 to form a ring-shaped closed water curtain, which is the first water curtain w1. The water flow bucket 6 is a tapered bucket structure with a wide top and a narrow bottom, and is provided with a vertical extension section at the bottom, and the water flow hole 62 is located inside the extension section.

[0043] In the specific implementation process, the output end of the water flow pipeline 61 is uniformly distributed on the top of the water flow bucket 6, the liquid medicine can uniformly cover the inside of the water flow bucket 6 and flow downward along the inside to pass through the water flow hole 62 to form the first water curtain w1.

[0044] As Figure 2 and Figure 3 The top of the desulfurization platform 3 is provided with a water tank 33 with a drain structure, specifically, the desulfurization platform 3 includes a main body 31 connected with the inside wall of the tower body 1, the water tank 33 is arranged on the top surface of the main body 31, and the bottom of the water tank 33 is a inclined surface structure, and the low-lying area is provided with a drain structure.

[0045] Further, the drain structure is a drain hole 34 longitudinally penetrating the main body 31, so that the accumulated water in the water tank 33 can be discharged downward.

[0046] The top center of the water tank 33 is provided with a splashback table 5, which corresponds to the falling position of the liquid medicine on the water flow bucket 6 and can guide the liquid medicine to uniformly splash upward, and after upward, it forms another ring-shaped closed water curtain, which is the second water curtain w2. Specifically, the splashback table 5 is a circular ring structure, and the top is provided with a guide groove 51 with a ring-shaped slot structure, the first water curtain w1 falls to the inside end of the guide groove 51, and flows outward along the guide groove 51 and then upward, and after extending outward, it falls, and in this process, the second water curtain w2 is formed.

[0047] The anti-splashing table 5 plays a role in receiving the water of the first water curtain w1 and splashing it outward to form the second water curtain w2.

[0048] In combination Figure 2 , Figure 3 and Figure 5 , the desulfurization platform 3 is provided with a plurality of air holes 32 below the coverage area of the second water curtain w2, the air holes 32 longitudinally penetrate the desulfurization platform 3, so that the exhaust gas below can pass through the desulfurization platform 3 upward through the air holes 32, and the uniformly distributed air holes 32 can also uniformly divide the airflow into a plurality of small airflows, on the one hand, so that the airflow flows upward uniformly, increasing the flow operation area; on the other hand, the airflow velocity is slowed down, which can be matched with the water curtain in the subsequent process, so that the gas passes through the water curtain softly, increases the gas-liquid contact area and time, and improves the desulfurization efficiency.

[0049] Further, the desulfurization platform 3 is provided with an overflow pipeline 41 at the bottom, the output end of the overflow pipeline 41 extends to above each air hole 32, and each end is connected with an overflow cover 4, the overflow cover 4 in the embodiment is mushroom-shaped, and in other embodiments, umbrella-shaped structures can also be used, which plays a role in guiding the water flow. The overflow pipeline 41 is in communication with the external pipeline, which can transport the liquid medicament to the overflow cover 4, the liquid medicament can flow down along the top profile of the overflow cover 4, forming another annular closed water curtain, which is the third water curtain w3, each third water curtain w3 covers an air hole 32, as shown in Figure 3 .

[0050] Further in combination with Figure 3 and Figure 4 , the solid arrows in the figure represent the gas flow path, and the hollow arrows represent the liquid medicament flow path. In the specific implementation process, the gas input by the air inlet channel 2 needs to be output by the air outlet 11 after passing through the air holes 32, the third water curtain w3, the second water curtain w2, the first water curtain w1, the water flow hole 62 and the demister 7. In this process, the first water curtain w1, the second water curtain w2 and the third water curtain w3 respectively serve as a blocking body, which forms three interception surfaces on the gas flow path, and the gas needs to penetrate the interception surfaces in sequence. Since the gas flow rate is weakened, it cannot easily break through the interception surface. Before penetrating the interception surface, the gas has contacted the inner side of the water curtain, so a large-scale reduction reaction will occur here to eliminate the sulfides in the exhaust gas. When the gas accumulates to a certain extent at the front side of the interception surface, it will flow through the interception surface and enter the front end of the next interception surface, and the above process is repeated, thereby greatly improving the desulfurization efficiency. The structure and layout of the multiple water curtains can also effectively reduce the gas overflow. Of course, compared with the traditional atomizing nozzle method, the gas-liquid contact structure of the water curtain can eliminate the hidden danger of high failure rate of the atomizing nozzle.

[0051] Further, asFigure 4 As shown, the main body 31 is located at the intersection of the water tank 33 and the air hole 32 is provided with a boss 37, the boss 37 is used to prevent the accumulated water in the water tank 33 into the air hole 32.

[0052] Embodiment 2:

[0053] On the basis of embodiment 1, in order to improve the third water curtain w3, so that the third water curtain w3 has a larger coverage area, such as Figure 6 As shown, the outer side end of the overflow cover 4 is provided with an upwardly curved turned edge 42, and the inner angle between the turned edge 42 and the horizontal plane is an acute angle.

[0054] The structure design of the turned edge 42 makes the water flow from the top of the overflow cover 4 to the outer side end of the overflow cover 4, which will convert part of the gravitational potential energy into kinetic energy, helping to increase its own flow rate upward, and then fall into the water tank 33 through a higher parabolic profile, which can greatly improve the coverage area of the third water curtain w3, making the first water curtain desulfurization more efficient.

[0055] Embodiment 3:

[0056] On the basis of embodiment 1, such as Figure 7 As shown, the water flow 6 and the demister 7 are also provided with an atomizing spray frame 8, and a plurality of atomizing nozzles are uniformly distributed on the atomizing spray frame 8, which is in communication with the external pipeline and can spray liquid medicine downward. By setting the atomizing spray at the rear end of the water flow 6, it is helpful to ensure that the gas is fully detached, and it can also further prevent the gas from escaping through the water curtain. Since the front end has been subjected to desulfurization treatment by multiple water curtains, the working load of the atomizing spray frame 8 is greatly reduced, which makes the nozzle failure not as high frequency as the traditional single atomizing spray method.

[0057] Embodiment 4:

[0058] On the basis of embodiment 1, combined with Figure 8 As shown, the desulfurization platform 3 and the tower body 1 are provided with a floating mechanism, which is used to adapt to the water flow intensity of the first water curtain w1, and can match the height according to different intensity changes, so as to ensure the stability of the splash effect of the splash table 5, that is, to ensure the structural stability of the second water curtain w2.

[0059] Specifically, the floating mechanism includes a movable slot 13 on the inner side wall of the tower body 1, a vertical guide rod 14 is arranged in the movable slot 13, and a plurality of sliding blocks 38 adapted to the guide rod 14 are arranged at the outer side ends of the desulfurization platform 3. The sliding blocks 38 are sleeved on the guide rod 14 and can slide up and down along the guide rod 14. The guide rod 14 is threadedly connected with an adjusting nut 16 below the sliding blocks 38. A spring 15 is arranged between the adjusting nut 16 and the sliding blocks 38. By rotating the adjusting nut 16, the tension of the spring 15 can be adjusted to control the sensitivity. The spring 15 provides elastic support for the desulfurization platform 3. When the impact force of the first water curtain w1 is disturbed, the spring 15 can be correspondingly contracted or extended and then kept stable by using the elastic force characteristics of the spring 15, so that a tension self-adjusting system is formed between the desulfurization platform 3 and the first water curtain w1, which helps to ensure the structural stability of the second water curtain w2. In order to prevent gas from escaping from the gap structure between the desulfurization platform 3 and the inner side wall of the tower body 1, a baffle 35 is arranged at the outer peripheral position of the bottom of the desulfurization platform 3. A sealing ring 36 is arranged between the baffle 35 and the inner side wall of the tower body 1, which can further play a sealing effect. In the specific implementation process, the sealing ring 36 can be coated with lubricating material, so that it will not excessively affect the up-and-down movement of the desulfurization platform 3.

[0060] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for part of the technical features. The modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
