Description

Technical Field

[0001] The utility model relates to the technical field of organic chemical experiments, in particular to an organic gas desulfurization device for experiments. Background Art

[0002] In organic chemistry experiments, many reactions generate sulfur-containing organic gases (such as hydrogen sulfide and mercaptans). These gases not only have a pungent odor but are also harmful to the health of experimenters, can corrode laboratory equipment, and pollute the environment. Existing methods for removing sulfur from organic gases primarily include liquid absorption (such as alkaline solution absorption and oxidative absorption) and solid adsorption (such as activated carbon adsorption and molecular sieve adsorption). Simple devices commonly used in laboratories often employ single-stage treatment, such as directly passing the gas through an absorption bottle or column filled with alkaline solution or activated carbon. However, these devices have significant drawbacks. For example, single-stage treatment (especially relying solely on alkaline solution) has low removal efficiency for certain poorly soluble organic sulfur compounds (such as mercaptans), making it difficult to meet strict emission or recovery requirements. Furthermore, when activated carbon is used as the adsorbent, saturation requires disassembly and replacement of the device, which is cumbersome and time-consuming.

[0003] Therefore, it is necessary to provide a new experimental organic gas desulfurization device to solve the above technical problems. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] See also Figures 1 to 5 The embodiment of the present invention provides an experimental organic gas desulfurization device, which includes a treatment bottle 1, an ammonia storage tank 4 and a filter box 5.

[0025] In the embodiments of the present invention, please refer to Figures 1 to 5 An alkaline solution 9 is stored in the treatment bottle 1, and an L-shaped air inlet pipe 11 is fixedly installed on the treatment bottle 1, the bottom pipe opening of the air inlet pipe 11 is close to the inner bottom wall of the treatment bottle 1, and a control A valve 111 is fixedly installed on the pipe opening of the air inlet pipe 11 located outside the treatment bottle 1, and a bottle cap 2 with a threaded fixed connection is installed on the bottle mouth of the treatment bottle 1, and a plurality of atomizing nozzles 3 are fixedly installed on the inner top wall of the bottle cap 2;

[0026] The experimental organic gas desulfurization device also includes an ammonia water storage tank 4, which is equipped with a liquid guide tube 41, and the liquid guide tube 41 is connected to the liquid inlet tube 31 on the bottle cap 2, and the liquid inlet tube 31 is connected to the liquid inlet of each atomizing nozzle 3, and a control C valve 411 is fixedly installed on the liquid guide tube 41, and a drainage pump is installed in the ammonia water storage tank 4, and the output end of the drainage pump is connected to the liquid inlet of the liquid guide tube 41.

[0027] It should be noted that: the sulfur-containing gas generated during the experiment is connected to the air inlet pipe 11 through a conduit, and then the control valve A 111 is opened, so that the sulfur-containing gas is discharged into the treatment bottle 1 and reacts with the alkaline solution 9 to achieve desulfurization treatment. The gas then floats up and is discharged into the filter box 5 through the exhaust pipe 21. While the gas floats up, the drainage pump is turned on and the control valve C 411 is controlled to drive the atomizing nozzle 3 to spray the floating gas, so that the gas fully reacts with the ammonia water, thereby further desulfurizing the gas.

[0028] Furthermore, a drain pipe 12 is installed on the bottle body of the treatment bottle 1 near the bottom, and a control B valve 121 is installed on the drain pipe 12. In this application, the treatment bottle 1 is made of transparent material, so when the liquid in the treatment bottle 1 rises to a predetermined height, the control B valve 121 is opened to discharge the alkaline solution 9 in the treatment bottle 1 (a container is used to receive the discharged liquid), wherein the alkaline solution 9 in this application can be sodium hydroxide.

[0029] In the embodiments of the present invention, please refer to Figures 1 to 5 The air inlet of the filter box 5 is connected to the exhaust pipe 21 on the bottle cap 2 through the air guide pipe 51, and a number of evenly distributed exhaust holes 5a are provided at the tail of the filter box 5, and a number of equidistantly distributed and vertically arranged insertion grooves 5b are provided on the filter box 5, and an activated carbon block 6 is inserted in each insertion groove 5b, and the activated carbon block 6 is inserted into the insertion groove 5b and slides in contact with the inner groove wall of the insertion groove 5b, and a stepped cover plate 8 for sealing the top insertion groove 5b is installed on the filter box 5. The notch at the top of the insertion groove 5b is a stepped notch, and the stepped cover plate 8 matches the stepped notch. A rotatably connected mouth-shaped rod 81 is installed on both sides of the stepped cover plate 8, and a plurality of evenly distributed hooks 52 are fixedly installed on both side walls of the filter box 5, and the hooks 52 correspond one-to-one to the insertion grooves 5b;

[0030] A plurality of springs 71 are fixedly mounted on the bottom of each insertion slot 5 b , and an abutting plate 7 is fixedly mounted on the top of the spring 71 .

[0031] It should be noted that when installing the activated carbon block 6, the activated carbon block 6 is inserted down along the insertion groove 5b until the activated carbon block 6 abuts against the abutting plate 7, and then the stepped cover plate 8 is closed and pressed down, so that the activated carbon block 6 pushes down the abutting plate 7 and compresses the spring 71, and then the mouth-shaped rod 81 is rotated so that the mouth-shaped rod 81 is buckled on the hook 52 to complete the installation of the activated carbon block 6;

[0032] When the sprayed gas enters the filter box 5, it is filtered by the multi-layer activated carbon block 6 to further purify the gas and reduce the emission of harmful substances in the gas.

[0033] It should also be noted that: when replacing the activated carbon block 6, the mouth-shaped rod 81 is rotated outward so that the mouth-shaped rod 81 is unscrewed from the hook 52 and the stepped cover 8 is removed. At this time, the elastic force of the spring 71 drives the abutment plate 7 to push the activated carbon block 6 upward, so that the activated carbon block 6 can slide out of the slot of the insertion slot 5b for a while, so that the staff can quickly take out the activated carbon block 6.

[0034] In the present application, an alkaline solution 9 is stored in the treatment bottle 1, and the bottom nozzle of the air inlet pipe 11 is close to the inner bottom wall, so that the sulfur-containing gas directly passes into the alkaline solution 9 to achieve primary wet desulfurization, and the atomizing nozzle 3 on the inner top wall of the bottle cap 2 supplies ammonia water through the ammonia water storage tank 4 to spray the floating gas to achieve secondary wet desulfurization. The multiple activated carbon blocks 6 in the filter box 5 form multi-stage dry filtration to further adsorb residual sulfur. The three-stage synergistic effect greatly improves the desulfurization efficiency.

[0035] In this embodiment, the frequency of replacing the activated carbon block 6 near the tail of the filter box 5 can be reduced.

[0036] It is worth noting that: the treatment bottle 1, bottle cap 2, drain pipe 12, stepped cover 8, mouth-shaped rod 81 and hook 52 are all made of polypropylene (PP). PP has excellent alkali resistance and its transparent material makes it easy to observe the internal state; the air inlet pipe 11, liquid guide pipe 41 and liquid inlet pipe 31 are all made of polytetrafluoroethylene (PTFE). PTFE has strong acid and alkali corrosion resistance and is suitable for transporting ammonia and alkaline solutions; the atomizing nozzle 3 is made of PTFE, which is resistant to blockage and corrosion, ensuring uniform spraying; the filter box 5, insertion groove 5b, and abutment plate 7 are all made of 316L stainless steel. 316L has better corrosion resistance than ordinary stainless steel in alkaline environment and high strength, and the spring 71 is made of 316L stainless steel, which is resistant to alkali corrosion and has stable elasticity.

[0037] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
