Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to dry desulfurization equipment. Background Art

[0002] The iron-making process involves extracting iron from iron ore through a series of smelting processes. When natural gas is used as fuel, it is necessary to purify the natural gas to prevent corrosion of the iron-making pipeline. By adopting a series of processes and technical means, impurities and pollutants in natural gas can be removed to ensure that it meets specific purity and quality standards. In order to facilitate the purification of natural gas and reduce pollution, a dry desulfurization equipment was born.

[0003] In the common natural gas purification process, the natural gas needs to be sent to a dry desulfurization device, and then the natural gas is desulfurized by the desulfurization plates inside the desulfurization device. However, when used for a long time, the desulfurization plates will cause wear when desulfurizing the natural gas, which may cause a decrease in the desulfurization rate. The desulfurization plates need to be replaced by stopping the purification device, which is time-consuming and labor-intensive, and to a certain extent, reduces work efficiency. Therefore, the utility model provides a dry desulfurization device to solve the problems raised in the above background technology. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dry desulfurization device, comprising a main body, a replacement mechanism is arranged inside the main body, and blocking mechanisms are arranged on both sides of the interior of the replacement mechanism. The main body comprises a cylinder, and the replacement mechanism comprises a shell, two desulfurization plates and two slide grooves, and pull plates are slidably arranged on both sides of the interior of the shell, and baffle rods are fixedly arranged at the rear ends of the upper ends of the two pull plates, and a plurality of first baffles are fixedly arranged at the upper ends of the two pull plates.

[0006] A support frame is fixedly provided on one side of the two pull plates close to each other, a plurality of clamping blocks are fixedly provided inside the two support frames near the lower end, blocking rods are fixedly provided on both sides of the upper ends of the two pull plates near the rear ends, the two blocking mechanisms include a plurality of second baffles and two limit blocks, and two second springs are fixedly connected between the two limit blocks and the two slide grooves;

[0007] Through the above technical solution, when the desulfurization plate needs to be replaced, a single pull plate is moved, and then the pull plate drives the desulfurization plate inside the support frame to move, and due to the movement of the pull plate, the baffle rod on the pull plate does not support the second baffle plate, and then the second baffle plate moves to form a seal with the first baffle plate, so that the natural gas continues to be desulfurized through another desulfurization plate, and the desulfurization plate can be replaced.

[0008] Furthermore, the two desulfurization plates are fixedly arranged inside the two support frames respectively, and the two support frames are slidably arranged on both sides of the inside of the shell;

[0009] Through the above technical solution, when the device is used, the common solid absorbents of the desulfurization plate include iron oxide and calcium oxide. During the dry desulfurization process, hydrogen sulfide will chemically react with the solid absorbent to generate sulfide, thereby removing the hydrogen sulfide.

[0010] Furthermore, a connecting block is fixedly provided on one side of the front ends of the two support frames close to each other, and a first spring is fixedly connected between the two connecting blocks;

[0011] Through the above technical solution, when the device is used, the pulling plate can be reset by the first spring, so that the desulfurization plate can be installed conveniently.

[0012] Furthermore, the two slide grooves are respectively opened on both sides of the rear end of the housing, and the two limit blocks are respectively slidably arranged inside the two slide grooves;

[0013] Through the above technical solution, when the device is used, the limit block can be conveniently controlled to move horizontally through the slide groove to prevent deviation.

[0014] Further, four connecting rods are fixedly arranged at the front and rear ends of the plurality of second baffles, and the two limit blocks are fixedly arranged at the upper ends of two of the four connecting rods;

[0015] Through the above technical solution, when the device is used, the position of the second baffle plate can be limited by the limit block, so that the first baffle plate and the second baffle plate can be closed to replace the desulfurization plate.

[0016] Furthermore, a sealing cover is fixedly provided at the upper end of the cylinder, and a feed pipe is fixedly provided inside the sealing cover close to the upper end;

[0017] Through the above technical solution, when the device is used, the sealing cover can be used to conveniently protect the device.

[0018] Furthermore, a discharge pipe is fixedly arranged at the lower end of the inner front end of the cylinder, and the shell is fixedly arranged inside the cylinder;

[0019] Through the above technical solution, when the device is used, the desulfurized natural gas can be conveniently supplied to the iron and steel plant through the discharge pipe.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model proposes a dry desulfurization equipment. When the desulfurization plate needs to be replaced, a single pull plate is moved, and then the pull plate drives the desulfurization plate inside the support frame to move. Moreover, due to the movement of the pull plate, the baffle rod on the pull plate does not support the second baffle plate. Then the second baffle plate moves to form a seal with the first baffle plate, so that the natural gas can continue to be desulfurized through another desulfurization plate, preventing the normal use of the natural gas purification process from being affected. At the same time, it is convenient to replace the desulfurization plate, saving time and effort, and improving work efficiency.

[0022] 2. The utility model proposes a dry desulfurization equipment. When using this device, the desulfurization plate can be easily installed and disassembled through the block inside the support frame, thereby improving work efficiency. At the same time, through the second spring, when the support plate is moved, the first baffle plate and the second baffle plate can be conveniently moved to form a closure, so that the desulfurization plate can be replaced.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example:

[0033] Reference Figure 1-6 , the utility model provides an embodiment: a dry desulfurization device, including a main body 1, a replacement mechanism 2 is arranged inside the main body 1, and blocking mechanisms 3 are arranged on both sides of the interior of the replacement mechanism 2, the main body 1 includes a cylinder 101, a sealing cover 102 is fixedly arranged on the upper end of the cylinder 101, a feed pipe 103 is fixedly arranged on the interior of the sealing cover 102 near the upper end, a discharge pipe 104 is fixedly arranged on the front end of the cylinder 101 near the lower end, a shell 201 is fixedly arranged inside the cylinder 101, the replacement mechanism 2 includes a shell 201, two desulfurization plates 206 and two slide grooves 204, a pull plate 202 is slidably arranged on both sides of the interior of the shell 201, the two desulfurization plates 206 are respectively fixedly arranged inside two support frames 205, and the two support frames 205 are slidably arranged on both sides of the interior of the shell 201;

[0034] Common solid absorbents for the desulfurization plate 206 include iron oxide and calcium oxide. During the dry desulfurization process, hydrogen sulfide will chemically react with the solid absorbent to generate sulfide, thereby removing the hydrogen sulfide. The common dry desulfurization reaction formula can be expressed as: Fe2O3+3H2S->2FeS+3H2O. When using this device, natural gas enters the interior of the cylinder 101 through the feed pipe 103, and then passes through the desulfurization plate 206 for desulfurization.

[0035] The upper ends of the two pull plates 202 are fixedly provided with a stopper 209 near the rear end, the inner parts of the two pull plates 202 are fixedly provided with a plurality of first stoppers 203 near the upper ends, the two pull plates 202 are fixedly provided with a support frame 205 on the side close to each other, the inner parts of the two support frames 205 are fixedly provided with a plurality of clamping blocks 210 near the lower ends, the upper ends of the two pull plates 202 are fixedly provided with a stopper 209 on both sides near the rear ends, the two blocking mechanisms 3 include a plurality of second stoppers 302 and two limit blocks 303, two second springs 304 are fixedly connected between the two limit blocks 303 and the two slide grooves 204, the front ends of the two support frames 205 are fixedly provided with a connecting block 207 on the side close to each other, the two connecting blocks 207 are fixedly connected with a first spring 208, the two slide grooves 204 are respectively opened on both sides of the inner part of the shell 201 near the rear end, the two limit blocks 303 are respectively slidably arranged in the two slide grooves 204, and the front and rear ends of the plurality of second stoppers 302 are fixedly provided with four connecting rods 301;

[0036] The limit block 303 is used to limit the moving position of the second baffle 302, so that the first baffle 203 and the second baffle 302 can form a closed position to replace the desulfurization plate 206. At the same time, the pull plate 202 can be reset by the first spring 208 to facilitate the installation of the desulfurization plate 206. When the desulfurization plate 206 needs to be replaced, the single pull plate 202 is moved, and then the pull plate 202 drives the desulfurization plate 206 inside the support frame 205 to move. In addition, due to the movement of the pull plate 202, the baffle rod 209 on the pull plate 202 does not support the second baffle 302. Then the second baffle 302 moves to form a seal with the first baffle 203, so that the natural gas continues to be desulfurized through another desulfurization plate 206, and the desulfurization plate 206 can be replaced.

[0037] Working principle: When using this device, first, natural gas enters the interior of the cylinder 101 through the feed pipe 103, and then desulfurizes through the desulfurization plate 206. When the desulfurization speed decreases, first move the single pull plate 202, and then the pull plate 202 drives the desulfurization plate 206 inside the support frame 205 to move, and because the pull plate 202 moves, the baffle 209 on the pull plate 202 does not support the second baffle 302, and then the second baffle 302 moves through the second spring 304, thereby forming a seal with the first baffle 203, allowing the natural gas to continue to be desulfurized through another desulfurization plate 206. Finally, the desulfurization plate 206 is taken out for replacement, and then reset by the first spring 208.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
