Description

Technical Field

[0001] The utility model belongs to the technical field of gas purification, and in particular relates to a hydrogen sulfide gas purification device. Background Art

[0002] Carbon capture, utilization, and storage (CCUS) is a technology that permanently reduces CO2 emissions by separating it from industrial processes, energy use, or the atmosphere and using or storing it. CCUS is considered an effective way to reduce greenhouse gas emissions and is crucial for addressing climate change.

[0003] With the growing awareness of energy conservation, emission reduction, and green production, carbon capture technology has been widely applied in various industrial production processes, including but not limited to cement and steel production, petrochemicals, waste incineration, and power generation. These industries generate large amounts of carbon dioxide during their production processes, and carbon capture technology can effectively reduce their carbon emissions.

[0004] Among them, when steel slag powder is subjected to carbon dioxide mineralization treatment, since the steel slag contains sulfides, hydrogen sulfide gas will be produced during the reaction with carbon dioxide. Hydrogen sulfide gas is a colorless, toxic acidic gas with a strong pungent odor. Therefore, in order to ensure the safety of workshop workers, a gas purification device must be installed at the pipeline or pump where hydrogen sulfide gas may overflow. However, the efficiency and effect of existing gas purification devices on hydrogen sulfide gas treatment still need to be further improved, and it is not convenient to replace consumables, making it inconvenient to use overall. At the same time, some gas purification equipment may still experience hydrogen sulfide leakage and accidental discharge, which requires further optimization and improvement.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a hydrogen sulfide gas purification device.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, a hydrogen sulfide gas purification device in one embodiment of the present invention includes a purification box 1 and an air inlet pipe 2.

[0035] Among them, the purification box 1 is placed at a pipeline or pump where hydrogen sulfide gas may overflow. A filter chamber 101, a flow chamber 102 and a purification chamber 103 are provided in the purification box 1. The filter chamber 101 is used to install a filter net 1012 to filter the gas, the flow chamber 102 is used for gas flow, and the purification chamber 103 is used to accommodate the purification liquid 1031.

[0036] In addition, two pairs of guide rails 1011 are installed on the inner wall of the filter cavity 101, and the guide rails 1011 are used to support the filter screen 1012. The two pairs of guide rails 1011 are provided with a filter screen 1012, which can filter the gas transported by the intake pipe 2 to remove impurities in the gas.

[0037] Preferably, in a pair of filter screens 1012 , the mesh density of the lower filter screen 1012 is greater than the mesh density of the upper filter screen 1012 , thereby ensuring the filtering effect of the filter screen 1012 on gas.

[0038] Specifically, a first through slot 1013 is provided on the side wall of the filter cavity 101, and the filter cavity 101 is connected to the flow cavity 102 through the first through slot 1013. The gas filtered by the filter screen 1012 can enter the flow cavity 102 through the first through slot 1013.

[0039] In addition, the purification box 1 is hinged with a first cover door 1014, which corresponds to the filter chamber 101. By opening the first cover door 1014, the filter screen 1012 can be cleaned or replaced, which is convenient for the staff to operate.

[0040] like Figures 1 to 7 As shown, a first straight tube 1021 is installed in the flow chamber 102, and a plurality of evenly distributed first spray heads 1022 are connected to the first straight tube 1021. Clean water 105 in the first straight tube 1021 can be sprayed out by the plurality of first spray heads 1022. Since hydrogen sulfide gas is soluble in water, the clean water 105 can absorb the hydrogen sulfide gas in the flowing gas in the flow chamber 102, thereby achieving the effect of initially removing the hydrogen sulfide gas.

[0041] A first baffle 1023 is connected to the sidewall of the flow chamber 102. The first baffle 1023 corresponds to the first through slot 1013 and is located above the first through slot 1013. The first baffle 1023 acts as a barrier, preventing the clean water 105 sprayed by the first spray head 1022 from passing through the first through slot 1013 and entering the filter chamber 101.

[0042] In addition, a drain groove 1024 is provided on the bottom wall of the flow chamber 102, and the flow chamber 102 is connected to the storage chamber 104 through the drain groove 1024. The clean water 105 sprayed by the first spray head 1022 will flow back into the storage chamber 104 through the drain groove 1024, so that the clean water 105 can be recycled.

[0043] like Figures 1 to 7As shown, a purification liquid 1031 is provided in the purification chamber 103. The purification liquid 1031 can be an alcohol or a petroleum solvent. Therefore, when the gas passes through the purification liquid 1031, the purification liquid 1031 can absorb the hydrogen sulfide gas in the gas to achieve the effect of purifying the gas again, making it difficult for the hydrogen sulfide gas to escape and leak and pollute the environment.

[0044] The inner wall of the purification chamber 103 is provided with a second through-groove 1032, which connects the flow chamber 102 to the purification chamber 103. A first gas collection hood 1033 is located outside the second through-groove 1032. A gas pipe 1034 is connected to the first gas collection hood 1033, one end of which is located within the purification liquid 1031. Gas flowing within the flow chamber 102 enters the first gas collection hood 1033 through the second through-groove 1032 and is then transported to the purification liquid 1031 via the gas pipe 1034. The purification liquid 1031 is then used to further purify the hydrogen sulfide in the gas. The provision of the gas pipe 1034 prevents backflow of the purification liquid 1031, ensuring normal gas flow.

[0045] Furthermore, a second straight pipe 1035 is connected to the gas pipe 1034, to which are connected several evenly distributed second injection nozzles 1036. Gas in the gas pipe 1034 enters the second straight pipe 1035 and is then discharged through the several second injection nozzles 1036, allowing the gas to fully contact the purification liquid 1031, ensuring that the purification liquid 1031 can fully absorb and remove the hydrogen sulfide in the gas.

[0046] Specifically, a grid 1037 is positioned above the purified liquid 1031, and a second baffle 1038 is mounted on the grid 1037. The second baffle 1038 is used to block activated carbon balls 1039. A plurality of activated carbon balls 1039 are mounted on the grid 1037, and are located on the side of the second baffle 1038 away from the gas pipe 1034. The activated carbon balls 1039 filter the gas purified by the purified liquid 1031, not only removing hydrogen sulfide gas but also absorbing tiny droplets of the purified liquid 1031 contained in the gas, thereby eliminating hydrogen sulfide gas and tiny droplets of the purified liquid 1031 from the exhaust gas, thereby minimizing environmental pollution.

[0047] like Figures 1 to 7 As shown, the purification box 1 is further provided with a storage chamber 104, in which clean water 105 and a submersible pump 3 are placed. The output end of the submersible pump 3 is connected to the first straight pipe 1021. When the submersible pump 3 is running, the submersible pump 3 can absorb the clean water 105 and transport the clean water 105 to the first straight pipe 1021.

[0048] The top wall of the purification box 1 is provided with an air outlet 106, and the purification chamber 103 is connected to the outside world through the air outlet 106. The purified gas is finally discharged from the purification box 1 through the air outlet 106, so that the discharged gas does not contain hydrogen sulfide gas, thereby reducing the probability of hydrogen sulfide gas polluting the environment.

[0049] In addition, a second cover door 107 is hingedly connected to the side wall of the purification box 1. The second cover door 107 corresponds to the activated carbon balls 1039, making it easy to replace and replenish the activated carbon balls 1039.

[0050] Specifically, a pair of replenishing pipes and a pair of observation plates are provided on the side wall of the purification box 1 , and the pair of replenishing pipes and the observation plates correspond to the purification chamber 103 and the storage chamber 104 respectively, and are used to replace the purification liquid 1031 and the clean water 105 .

[0051] like Figures 1 to 7 As shown, the air inlet pipe 2 is connected to the purification box 1 and communicates with the filter chamber 101. An exhaust fan is installed on the air inlet pipe 2, and one end of the air inlet pipe 2 is connected to a second gas collection hood 201. The second gas collection hood 201 is set at the pipeline where hydrogen sulfide gas may overflow. The exhaust fan can extract the gas near the pipeline. If hydrogen sulfide gas overflows, it will be directly sucked up by the exhaust fan.

[0052] Among them, one end of the air intake pipe 2 located in the filter cavity 101 is connected to the air expansion cover 202, so that the gas transported by the air intake pipe 2 can fully contact the filter 1012, making it difficult for the gas to accumulate and pass through the filter 1012, thereby improving the utilization rate of the filter 1012.

[0053] Preferably, the purification box 1 is equipped with a control box, which is electrically connected to the submersible pump 3 for controlling the operation of the submersible pump 3 .

[0054] In practice, the second gas collection hood 201 is positioned near a pipe where hydrogen sulfide gas may overflow. The exhaust fan on the intake pipe 2 is operated to extract gas from the pipe or near the pump. Any hydrogen sulfide gas that overflows is directly sucked in by the exhaust fan. The gas passes through the second gas collection hood 201 and the intake pipe 2 into the filter chamber 101 and is then discharged through the expansion hood 202.

[0055] The gas entering the filter chamber 101 is first filtered through a pair of filters 1012 to remove impurities. The filtered gas then flows through the first through-slot 1013 into the flow chamber 102. The submersible pump 3 is then operated to draw clean water 105 from the storage chamber 104. This water 105 is then transported to the first straight pipe 1021 and ejected through a plurality of first injection nozzles 1022. Since hydrogen sulfide is soluble in water, the clean water 105 absorbs the hydrogen sulfide in the flowing gas within the flow chamber 102, achieving a preliminary removal of the gas.

[0056] The gas in the flow chamber 102 can enter the first gas collecting hood 1033 through the second through groove 1032, and then be transported to the second straight pipe 1035 through the gas pipe 1034, and discharged through several second injection heads 1036, so that the gas is fully in contact with the purification liquid 1031. The purification liquid 1031 can be used to purify the hydrogen sulfide gas in the gas again.

[0057] The gas purified by the purification liquid 1031 is adsorbed by the activated carbon balls 1039 and then discharged from the purification box 1 through the gas outlet 106, so that the gas discharged from the purification box 1 does not contain hydrogen sulfide gas, thereby reducing the pollution caused by hydrogen sulfide gas to the environment.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
