Description

Technical Field

[0001] The utility model belongs to the field of ethanol preparation, and particularly relates to a gas filtration device for synthesizing ethanol from syngas. Background Art

[0002] In the production process of synthesizing ethanol from syngas, the purity of the gas plays a crucial role in the quality of the final product. However, there are some obvious deficiencies in the traditional gas filtration device in practical applications.

[0003] The traditional filtration device has poor effect in gas dispersion. The syngas tends to accumulate in the pipeline, resulting in uneven distribution when entering the filtration device, affecting the filtration efficiency and effect. There are also limitations in improving the filtration effect. Usually, only a single filtration method is adopted, which is difficult to fully remove the impurity particles in the gas and cannot meet the requirements of high-purity gas for synthesizing ethanol from syngas. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: a gas filtration device for synthesizing ethanol from syngas, including a filtration barrel, a filtration component, and a dispersion component.

[0005] An air outlet pipe is fixedly connected to the top of the filtration barrel, and a dispersion component is fixedly connected to the bottom. A filtration component is installed inside the filtration barrel.

[0006] The dispersion component includes a gas collecting pipe, a plurality of dispersion pipes, and a fixing plate. A plurality of round holes are correspondingly formed in the top wall of the gas collecting pipe and the fixing plate. The corresponding round holes in the gas collecting pipe and the fixing plate are connected by dispersion pipes. The dispersion pipes are used for dispersing gas. The round holes are annularly arranged along the central axis of the fixing plate. The outer wall of the fixing plate is fixedly connected to the bottom of the filtration barrel.

[0007] The filtration component includes a liquid collecting plate, two filter plates, and a ring shell. The two filter plates are respectively installed on the fixing blocks on the inner wall of the filtration barrel. The two filter plates are located above the fixing plate and are arranged at intervals. A plurality of through holes are provided on the two filter plates, and the through holes of the two filter plates are staggered. The liquid collecting plate is fixedly connected to the inner wall of the filtration barrel and is located above the filter plates. The liquid collecting plate is used for converging liquid. A diversion shell is correspondingly arranged on the filtration barrel for the liquid collecting plate. The outer wall of the ring shell is fixedly connected to the inner wall of the filtration barrel and is located above the liquid collecting plate. A plurality of nozzles are fixedly connected to the inner wall of the ring shell, and the nozzles are annularly arranged along the central axis of the ring shell. A liquid guide shell is arranged on the filtration barrel, and the inner end of the liquid guide shell is communicated with the outer wall of the ring shell.

[0008] A plurality of supporting feet are arranged at the bottom of the filtration barrel, and the supporting feet are annularly arranged along the central axis of the bottom of the filtration barrel.

[0009] An airtight door is arranged on the barrel body of the filtration barrel.

[0010] The collecting pipe is disc-shaped.

[0011] An auxiliary fixing block is arranged on the airtight door. The auxiliary fixing block is arranged corresponding to the fixing block and is used for supporting the filter plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By setting the dispersion component, the gas in the synthetic ethanol gas pipeline enters the collecting pipe through the air inlet pipe, and then passes through the dispersion pipe through the round holes on the fixing plate and is dispersed and transported to the filtering barrel, avoiding gas aggregation and improving the uniformity and efficiency of gas filtration;

[0014] 2. By setting the filtering component and arranging two filter plates with staggered through holes, the particles in the gas can be initially filtered, and combined with the silicone oil sprayed by the nozzle to adsorb the particles in the gas, further improving the filtering effect and ensuring the purity of the gas during the synthesis of ethanol from syngas;

[0015] 3. The silicone oil sprayed by the filtering component of the present utility model will be guided along the liquid collecting plate and flow out of the outside through the diversion shell, facilitating the centralized treatment of the used silicone oil, thereby reducing the use cost;

[0016] 4. By setting the airtight door, when the filtering efficiency of the filter plate becomes poor or needs to be replaced, the filter plate can be slid out along the fixing block through the airtight door on the filtering barrel for replacement, which is convenient to operate and improves the maintenance efficiency of the equipment.

[0025] As Figure 1 - Figure 6 shown, a gas filtration device for synthesizing ethanol from syngas includes a filter barrel 1, a filter component 4, and a dispersion component 5. The filter barrel 1 is a cylindrical barrel. An air outlet pipe 2 is fixedly connected to the top of the filter barrel, and a dispersion component 5 is fixedly connected to the bottom. The filter component 4 is installed inside the filter barrel 1. A sealed door 3 is provided on the barrel body of the filter barrel 1, and a plurality of support feet 6 are provided at the bottom of the filter barrel 1, and the support feet 6 are annularly arranged along the central axis of the bottom of the filter barrel 1.

[0026] The dispersion component 5 includes a gas collecting pipe 54, a plurality of dispersion pipes 53, and a fixing plate 51. The outer wall of the fixing plate 51 is fixedly connected to the bottom of the filter barrel to form the bottom of the filter barrel. The gas collecting pipe 54 is disc-shaped, and a plurality of round holes are correspondingly opened on the top wall of the gas collecting pipe 54 and the fixing plate 51. The correspondingly opened round holes on the gas collecting pipe 54 and the fixing plate 51 are connected into one body through the dispersion pipes 53, so that the gas collecting pipe 54 is communicated with the fixing plate 51 through the dispersion pipes 53. The dispersion pipes are used to disperse gas into the filter barrel, and the round holes 52 are annularly arranged along the central axis of the fixing plate 51.

[0027] The filtering component 4 includes a liquid collecting plate 42, two filter plates 44, and an annular shell 41. The two filter plates 44 are respectively installed on the fixing blocks on the inner wall of the filtering barrel. The fixing blocks are semi-circular table surfaces facing the airtight door 3, and the filter plates are placed thereon. The airtight door 3 can also be provided with fixing blocks to assist in supporting the filter plate 44. The two filter plates 44 are located above the fixing plate 51 and are spaced apart. A number of through holes are provided on the two filter plates 44. The through holes on the two filter plates are staggered and of different sizes. The liquid collecting plate 42 is fixedly connected to the inner wall of the filtering barrel 1 and is located above the filter plate 44. The liquid collecting plate 42 is used to converge silicone oil. The liquid collecting plate is any one of the conventional liquid collecting plate structures, including components such as a riser cap, which will not be described in detail in this embodiment. A diversion shell 47 is provided on the filtering barrel 1 corresponding to the liquid collecting plate 42. The outer wall of the annular shell 41 is fixedly connected to the inner wall of the filtering barrel 1 and is located above the liquid collecting plate 42, in the upper part of the filtering barrel 1.

[0028] Working principle:

[0029] During use, the synthetic ethanol gas pipeline is connected to the dispersion component 5 at the bottom of the filtering barrel 1. When the synthetic ethanol gas enters the dispersion component 5 through an external pipeline, the gas will first enter the gas collecting pipe 54 through the air inlet pipe 55. Since a dispersion pipe 53 is provided on the gas collecting pipe 54, the gas can pass through the dispersion pipe 53 and pass through the round holes 52 on the fixing plate 51 and enter the filtering barrel 1, so as to disperse and transport the aggregated gas to the filtering barrel 1. The gas entering the filtering barrel 1 will be filtered by the two filter plates 44 with staggered through holes to initially filter the particles in the gas. Then, the silicone oil conduit is connected to the liquid guiding shell 45, so that the silicone oil can flow into the annular shell 41 through the liquid guiding shell 45 and be sprayed out through the nozzles 46. By combining the gas with the sprayed silicone oil, the particles in the gas are adsorbed, so as to further filter the particles in the gas and enter the next process through the air outlet pipe.

[0030] The sprayed silicone oil will flow along the outer wall of the liquid collecting plate 42 and flow out of the outside through the diversion shell 47, so as to centrally process the used silicone oil.

[0031] When the filtering efficiency of the two filter plates 44 deteriorates or needs to be replaced, only need to stop filtering the gas first, and then slide the filter plate 44 out along the fixing block 43 through the airtight door 3 on the filtering barrel 1, and the filter plate 44 can be replaced.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Structures, devices, and operation methods not specifically described and explained in the present utility model shall be implemented by conventional means in the art unless otherwise specified and limited.
