Description

Technical Field

[0001] The utility model relates to the technical field of purification and separation, in particular to a high-efficiency sulfur capture device. Background Art

[0002] Sulfur has low melting and boiling points and low hardness. At room temperature, sulfur exists in the form of rhombic sulfur (orthorhombic sulfur), with a rhombic appearance, a melting point of 112.8℃, and a density of 2.07 g / cm3. When it exceeds 95.6℃, it gradually transforms into another allotrope, which is needle-shaped and called monoclinic sulfur, with a density of 1.96 g / cm3 and a melting point of 119.O℃. When it is lower than 95.6℃, it slowly turns into orthorhombic sulfur. When liquid sulfur is just dissolved, it is a pale yellow flowing liquid. When it continues to be heated, it becomes brown and viscous. When it is heated again, the brown liquid flows again. When it boils at 444.6℃, it becomes a vapor composed of S2. When it is cooled, the gaseous sulfur condenses into sulfur powder (S8, commonly known as sulfur flowers), which can be used to purify sulfur. The capture of sulfur is often used in hydrogen sulfide synthesis gas or other smelting flue gas. In order to obtain clean gas, it is necessary to separate the sulfur element. For example, in the hydrogen sulfide synthesis process, elemental sulfur is reacted with hydrogen to produce hydrogen sulfide. The synthetic gas will be mixed with elemental sulfur. In this process, a sulfur capture device is an essential equipment.

[0003] In actual production, a bag filter + wire mesh demister structure is often used to capture and separate sulfur. The sulfur-containing gas is distributed to the filter bag through the air flow distribution arrangement, so that the gas is evenly distributed to the filter bag, and the sulfur dust is blocked on one side of the filter bag. The purified gas is discharged through the air outlet; when the dust on the surface of the filter bag continues to increase and the resistance reaches the set value, it is necessary to stop the machine to clean the intercepted powder. The intercepted powder is not easy to clean, which seriously affects the work efficiency. In addition, the discharge of sulfur after cleaning also causes secondary environmental pollution. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a high-efficiency sulfur capture device that can intercept sulfur in synthetic gas with high working efficiency. The intercepted sulfur can be discharged in a centralized manner without causing secondary pollution.

[0005] The high-efficiency sulfur capture device according to the embodiment of the utility model comprises:

[0006] Two sulfur-capturing cylinders, each of which is provided with a sulfur-capturing chamber, a side wall of the sulfur-capturing chamber being provided with a treatment gas inlet and a treatment gas outlet, and a bottom wall of the sulfur-capturing chamber being provided with a liquid drain pipe;

[0007] A process gas delivery device, comprising a process gas delivery pipe and a control valve, wherein the control valve is used to control the process gas delivery pipe to selectively connect to the process gas inlet of one of the two sulfur capture cylinders;

[0008] A heat exchange structure, comprising a heat exchange portion extending into the sulfur capture chamber, wherein the heat exchange portion is at least partially located between the process gas inlet and the process gas outlet, and the heat exchange portion is provided with a medium channel that is not interconnected with the sulfur capture chamber;

[0009] The medium conveying structure is used to input medium into the medium channel and output the medium in the medium channel, and the medium is a cooling medium or a heating medium.

[0010] The high-efficiency sulfur capture device according to the embodiment of the utility model has at least the following beneficial effects:

[0011] When in use, the control valve controls the treated gas delivery pipe to connect to the treated gas inlet on one of the sulfur-catching cylinders, and delivers the treated gas to the sulfur-catching chamber of the sulfur-catching cylinder. At the same time, the cooling medium is input into the medium channel of the heat exchange part through the medium delivery structure. The treated gas contacts the heat exchange part during the process of flowing from the treated gas inlet to the treated gas outlet, thereby exchanging heat with the cooling medium in the medium channel, so that the gaseous sulfur in the treated gas is condensed and sublimated into sulfur powder, so as to capture and separate the sulfur element in the treated gas and purify the gas. After working for a period of time, when excessive sulfur powder is adsorbed on the heat exchange part and the resistance is too large, the control valve controls the treated gas delivery pipe to connect to the treated gas inlet on another sulfur-catching cylinder, and the other sulfur-catching cylinder performs sulfur capture and purification work on the treated gas, while the original sulfur-catching cylinder performs sulfur element cleaning work. The process of cleaning sulfur element is: the heating medium is delivered to the medium channel of the heat exchange part through the medium delivery device to melt the sulfur powder adsorbed outside the heat exchange part, and the melted sulfur element is discharged through the drainage pipe at the bottom. By adopting the above-mentioned structural arrangement, the two sulfur-capturing cylinders can perform the purification work of the treated gas alternately. When one of the sulfur-capturing cylinders is purifying the treated gas by introducing a cooling medium into the medium channel of the heat exchange part, the other sulfur-capturing cylinder is cleaning the sulfur powder adsorbed on the heat exchange part by introducing a heating medium into the medium channel of the heat exchange part. The sulfur element can be cleaned conveniently without stopping the machine for cleaning, and the work efficiency is high. The intercepted sulfur element can be discharged collectively through the drain pipe and returned to the synthesis process of the synthetic gas for use without causing secondary pollution.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figure 1 and Figure 2As shown, a high-efficiency sulfur capture device of an embodiment of the utility model comprises: two sulfur capture cylinders 100, a process gas delivery device 200, a heat exchange structure 300, and a medium delivery structure. It should be noted that the process gas in this embodiment is hydrogen sulfide synthesis gas or other smelting flue gas mixed with sulfur. In order to obtain clean gas, the sulfur in the gas needs to be captured and separated.

[0034] In this embodiment, the sulfur capture cylinder 100 is vertically distributed, and a sulfur capture chamber 101 is provided in the sulfur capture cylinder 100. The side wall of the sulfur capture chamber 101 is provided with a processing gas inlet 102 and a processing gas outlet 103, and the bottom wall of the sulfur capture chamber 101 is provided with a drain pipe 104.

[0035] The process gas delivery device 200 includes a process gas delivery pipe 210 and a control valve 220. The control valve 220 is used to control the process gas delivery pipe 210 to selectively connect to the process gas inlet 102 of one of the two sulfur capture cylinders 100, that is, the control valve 220 is used to control the process gas delivery pipe 210 to connect to the process gas inlet 102 on one of the sulfur capture cylinders 100 or to control the process gas delivery pipe 210 to connect to the process gas inlet 102 on the other sulfur capture cylinder 100, so that the two sulfur capture cylinders 100 are arranged in parallel, and the process gas delivery pipe 210 is used to deliver the process gas. It is conceivable that the control valve 220 can be a three-way valve, the inlet of the three-way valve is connected to the process gas delivery pipe 210, the first outlet of the three-way valve is connected to the process gas inlet 102 of one of the sulfur capture cylinders 100 through a pipeline, and the second outlet of the three-way valve is connected to the process gas inlet 102 of the other sulfur capture cylinder 100 through a pipeline.

[0036] The heat exchange structure 300 includes a heat exchange portion extending into the sulfur capture chamber 101, and the heat exchange portion is at least partially located between the treatment gas inlet 102 and the treatment gas outlet 103, that is, the flow path of the treatment gas passes through the heat exchange portion, and the heat exchange portion is provided with a medium channel which is not interconnected with the sulfur capture chamber 101. Obviously, the medium channel is also at least partially located between the treatment gas inlet 102 and the treatment gas outlet 103.

[0037] The medium conveying structure is used to input medium into the medium channel and output medium in the medium channel. The medium is a cooling medium or a heating medium. It is conceivable that the cooling medium can be condensed water and the heating medium can be low-pressure steam.

[0038] Specifically, when in use, the control valve 220 controls the process gas delivery pipe 210 to connect to the process gas inlet 102 on one of the sulfur-catching cylinders 100, and delivers the process gas to the sulfur-catching chamber 101 of the sulfur-catching cylinder 100. At the same time, the cooling medium is input into the medium channel of the heat exchange part through the medium delivery structure. The process gas contacts the heat exchange part during the process of flowing from the process gas inlet 102 to the process gas outlet 103, thereby exchanging heat with the cooling medium in the medium channel, so that the gaseous sulfur in the process gas is condensed and sublimated into sulfur powder, so as to capture and separate the sulfur element in the process gas and purify the gas. Working After a period of time, when excessive sulfur powder is adsorbed on the heat exchange part and the resistance is too large, the control valve 220 controls the treated gas delivery pipe 210 to connect to the treated gas inlet 102 on another sulfur capture cylinder 100, and the other sulfur capture cylinder 100 performs sulfur capture and purification work on the treated gas, while the original sulfur capture cylinder 100 performs sulfur element cleaning work. The process of cleaning sulfur element is: heating medium is transported into the medium channel of the heat exchange part through the medium conveying device to melt the sulfur powder adsorbed outside the heat exchange part, and the melted sulfur element is discharged through the drain pipe 104 at the bottom. The high-efficiency sulfur capture device with the above-mentioned structure can make the two sulfur capture cylinders 100 perform the purification work of the treated gas alternately. When one of the sulfur capture cylinders 100 captures sulfur and purifies the treated gas by passing a cooling medium into the medium channel of the heat exchange part, the other sulfur capture cylinder 100 cleans the sulfur powder adsorbed on the heat exchange part by passing a heating medium into the medium channel of the heat exchange part. The sulfur element is easy to clean and there is no need to stop the machine for cleaning. The work efficiency is high. The intercepted sulfur element can be discharged collectively through the drain pipe 104 and returned to the synthesis process of the synthetic gas for use without causing secondary pollution.

[0039] It is conceivable that the pressure difference between the treated gas inlet 102 and the treated gas outlet 103 can be monitored to monitor whether there is excessive resistance in the sulfur capture cylinder 100, so that cleaning work can be carried out in time.

[0040] It can be understood that the medium conveying structure includes a medium input pipe 110 and a medium output pipe 120, the heat exchange part is provided with a heat exchange pipe 310, the medium channel is formed in the heat exchange pipe 310, one end of the heat exchange pipe 310 is connected to the medium input pipe 110, and the other end is connected to the medium output pipe 120. Obviously, the heat exchange pipe 310 is a tubular structure with a simple structure and convenient processing. It should be noted that the heat exchange pipe 310 is made of a heat-conducting material. Further, in order to effectively increase the heat exchange area, a plurality of heat exchange pipes 310 are provided, and any heat exchange pipe 310 is connected to the medium input pipe 110 at one end and the medium output pipe 120 at the other end.

[0041] It can be understood that the processing gas inlet 102 is located at the lower side of the heat exchange part, and the processing gas outlet 103 is located at the peripheral side of the heat exchange part, so that the processing gas can fully contact with the heat exchange part for heat exchange, thereby improving the purification effect. Further, in order to make the processing gas more fully contact with the heat exchange part for heat exchange, the processing gas inlet 102 and the processing gas outlet 103 are respectively located on opposite sides of the center line of the heat exchange part.

[0042] It can be understood that the sulfur capture cylinder 100 is provided with a first heat exchange chamber 105 and a second heat exchange chamber 106 which are not connected to the sulfur capture chamber 101 on the upper side of the sulfur capture chamber 101, the medium input pipe 110 is provided on the side wall of the first heat exchange chamber 105, and the medium output pipe 120 is provided on the side wall of the second heat exchange chamber 106, and any heat exchange tube 310 is connected to the first heat exchange chamber 105 at one end and connected to the second heat exchange chamber 106 at the other end, and the first heat exchange chamber 105 and the second heat exchange chamber 106 are connected through the heat exchange tube 310. Obviously, since there are multiple heat exchange tubes 310, the medium input pipe 110 and the medium output pipe 120 can only be connected to multiple heat exchange tubes 310. There are two forms. One is that the medium input pipe 110 and the medium output pipe 120 are arranged one by one with the heat exchange pipe 310, which will cause numerous pipes, which is very troublesome to arrange and inconvenient to maintain. The other form is the form adopted in this embodiment. By setting the first heat exchange chamber 105 and the second heat exchange chamber 106, each heat exchange pipe 310 is connected to the first heat exchange chamber 105 at one end and the second heat exchange chamber 106 at the other end, so that only one medium input pipe 110 is connected to the first heat exchange chamber 105 and one medium output pipe 120 is connected to the second heat exchange chamber 106, without setting too many pipes, the structure is simple and easy to maintain. In some embodiments, the first heat exchange chamber 105 and the second heat exchange chamber 106 are arranged horizontally opposite to each other.

[0043] It can be understood that the sulfur capture cylinder 100 includes a cylinder 130 with an opening at the upper end and an upper head 140 covered on the upper end of the cylinder 130, and the heat exchange structure 300 also includes a mounting portion 320 for fixing the heat exchange tube 310, and multiple heat exchange tubes 310 are fixed on the lower side of the mounting portion 320, and the mounting portion 320 is detachably arranged between the cylinder 130 and the upper head 140 to facilitate the disassembly and maintenance of the heat exchange structure 300; wherein the sulfur capture chamber 101 is formed between the mounting portion 320 and the cylinder 130, and the mounting portion 320 seals the opening at the upper end of the cylinder 130 to form the sulfur capture chamber 101 between the cylinder 130, the treated gas inlet 102 and the treated gas outlet 103 are both arranged on the cylinder 130, and the first heat exchange chamber 105 and the second heat exchange chamber 106 are It is formed between the upper head 140 and the mounting portion 320, the medium input pipe 110 and the medium output pipe 120 are both arranged on the upper head 140, and both ends of the heat exchange tube 310 are fixed on the mounting portion 320; in some embodiments, a vertically distributed partition 142 is arranged between the upper head 140 and the mounting portion 320, and the partition 142 divides the space between the upper head 140 and the mounting portion 320 into two transversely opposite cavities, one of which is the first heat exchange cavity 105 and the other is the second heat exchange cavity 106. Specifically, the partition 142 is fixed to the inner wall of the upper head 140, and the upper end surface of the mounting portion 320 is provided with an embedded groove, and a gasket is arranged in the embedded groove. The bottom end of the partition 142 is embedded in the embedded groove and abuts against the gasket to separate the first heat exchange cavity 105 and the second heat exchange cavity 106. It can be imagined that the heat exchange tube 310 can be set as a U-shaped tube or a coil.

[0044] It can be understood that the bottom end of the upper head 140 is provided with a first connecting flange 141, the top end of the cylinder 130 is provided with a second connecting flange 131 and connected to the first connecting flange 141 through fasteners to achieve a detachable connection between the upper head 140 and the cylinder 130, the mounting portion 320 is set as a plate-like structure, the mounting portion 320 is horizontally distributed and clamped between the first connecting flange 141 and the second connecting flange 131, and the mounting portion 320 is clamped and fixed by the first connecting flange 141 and the second connecting flange 131, so as to achieve the installation and fixation of the heat exchange structure 300. When the heat exchange structure 300 needs to be disassembled, it is only necessary to remove the fasteners between the first connecting flange 141 and the second connecting flange 131, and then remove the upper head 140, so that the heat exchange structure 300 can be taken out, and the operation is very convenient. Obviously, a sealing structure is provided between the mounting portion 320 and the first connecting flange 141 and between the mounting portion 320 and the second connecting flange 131.

[0045] In one specific embodiment, the heat exchange structure 300 is set as a U-tube heat exchanger, which includes a tube sheet, a plurality of U-tubes and a plurality of baffles. The tube sheet is also provided with a plurality of tie rods for fixing the baffles, and a plurality of U-tubes are arranged in layers, wherein the tube sheet is the mounting portion 320 in the above embodiment, and the U-tube is the heat exchange tube 310 in the above embodiment. The U-tube heat exchanger occupies a relatively small space, has a compact structure, and has a high heat exchange efficiency, which can reach more than 90%, can effectively reduce energy consumption, and improve production efficiency. In addition, the U-tube heat exchanger is easy to maintain, has a simple structure, is easy to clean and replace, and has a low maintenance cost.

[0046] It is understandable that a valve is provided on the drain pipe 104, and the valve is used to control the on and off of the drain pipe 104. A steam jacket 150 is provided on the outer side of the bottom of the sulfur capture cylinder 100 to form a steam layer on the periphery of the sulfur capture chamber 101. The steam jacket 150 is provided with a steam inlet pipe 151 and a steam condensate outlet pipe 152. The steam inlet pipe 151 is used to supply steam to the steam layer so that the device maintains the processing temperature. It is understandable that the setting of the drain pipe 104 will have a certain influence on the sealing effect in the sulfur capture chamber 101. In order to improve the sealing effect, when cleaning the sulfur powder, the valve can be opened first to discharge a part of the melted sulfur through the drain pipe 104, and then the valve is closed to allow a part of the sulfur to be trapped in the sulfur capture chamber 101. By passing steam through the steam jacket 150 for heating, the sulfur retained at the bottom of the sulfur capture chamber 101 can always remain in a liquid state, thereby achieving a liquid sealing effect and preventing the treated gas from leaking from the drain pipe 104 during subsequent purification of the treated gas. Obviously, the liquid level of the retained liquid sulfur needs to be lower than the height of the treated gas inlet 102.

[0047] It is understandable that a temperature detection port is also provided on the side wall of the sulfur capture chamber 101 to facilitate monitoring of the processing temperature in the sulfur capture chamber 101 .

[0048] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
