Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen sulfide, in particular to a purifier for hydrogen sulfide gas. Background Art

[0002] Hydrogen sulfide is an inorganic compound with the chemical formula H2S and a molecular weight of 34.076. It is a flammable acidic gas under standard conditions. It is colorless and has the smell of rotten eggs at low concentrations. It has the smell of sulfur at extremely low concentrations and is highly toxic. Its aqueous solution is hydrosulfuric acid, which is weaker in acidity, weaker than carbonic acid, but stronger than boric acid. It is soluble in water and easily soluble in alcohols, petroleum solvents and crude oil.

[0003] After searching, it is proposed in a hydrogen sulfide gas detection alarm system with patent publication number CN218546699U that "the utility model relates to the field of hydrogen sulfide detection technology. The hydrogen sulfide gas detection alarm system is equipped with two hydrogen sulfide detectors. The first hydrogen sulfide detector is mainly used to detect hydrogen sulfide in the sampled gas, and then the sampled gas will be purified through the water tank and the air filter box so that the discharged gas will not pollute the atmosphere. The second hydrogen sulfide detector detects the exhaust gas. Once the exhaust gas hydrogen sulfide exceeds the standard, an alarm will be sounded to notify the staff to replace the filter liquid and filter element in the water tank to prevent air pollution."

[0004] However, the above scheme still has certain shortcomings in actual use. In this scheme, only a water tank and an air filter box are used to purify the hydrogen sulfide gas, and each substance in the hydrogen sulfide gas is not purified, resulting in a significant reduction in the purification effect of the hydrogen sulfide gas.

[0026] By setting up a storage box 304, an electrocatalytic regenerator 306 and a gas-liquid separation layer 7, the absorption liquid in the storage box 304 is used to react with the hydrogen sulfide gas, thereby absorbing the hydrogen sulfide and stabilizing it into a mixed liquid, and then the extraction pump 305 is used to pump the mixed liquid into the electrocatalytic regenerator 306 for electrocatalytic regeneration reaction, so that the hydrogen sulfide in the mixed liquid is oxidized into sulfate, and finally the gas-liquid separation layer 7 can separate the mixed liquid into gas and liquid, so that the separated electrocatalyzed mixed liquid falls into the storage box 304 again, thereby realizing recycling and repeated utilization, so that the hydrogen sulfide gas undergoes multi-stage purification.

[0027] The reaction principle of the absorption liquid in the storage box 304, the electrocatalytic regenerator 306 and the gas-liquid separation layer 7 has been described in detail in a hydrogen sulfide gas purification system of patent publication number CN218741204U, and will not be further elaborated here.

[0028] A mounting recess 502 is provided at the bottom of the dust reduction chamber 5, and a waste residue box 504 is movably connected to the mounting recess 502 through a rotating pin 503. A water tank 505 is fixedly installed at the top of the purification box 1, and a copper sulfate solution is injected into the water tank 505. A shunt pipe 506 is fixedly installed at the bottom of the water tank 505 through a water pump. The water outlet end of the shunt pipe 506 is located inside the purification box 1 and is fixedly installed with an atomizing nozzle 507.

[0029] The reaction principle of copper sulfate solution has been described in detail in a hydrogen sulfide absorption device with patent publication number CN202321099028.6, and will not be further elaborated here.

[0030] By setting up a waste residue box 504, a water storage tank 505 and an atomizing nozzle 507, the copper sulfate solution in the water storage tank 505 can be sprayed in the dust reduction chamber 5 in the form of mist using the atomizing nozzle 507, so that the copper sulfate solution will form copper sulfide that is insoluble in general strong acids when reacting with the hydrogen sulfide gas that has been initially purified, and finally fall into the waste residue box 504 and wait for recovery by the staff, so that the hydrogen sulfide gas is subjected to secondary purification, thereby further improving the practicality of the purifier.

[0031] Specifically, an exhaust fan 601 is fixedly installed inside the front plate 6 , and a dustproof net 602 is arranged on the outer side of the exhaust fan 601 .

[0032] In this embodiment, the gas after the purification operation is finally discharged from the purification box 1 under the drive of the outlet fan 601, and the outlet fan 601 can be dust-proofed by using the dust-proof net 602.

[0033] Specifically, the bottom end of the connecting pipe 303 extends below the liquid level of the storage box 304 , and the bottom of the inner wall of the separation chamber 4 is connected to the storage box 304 .

[0034] In this embodiment, hydrogen sulfide gas is introduced into the storage box 304 below the liquid level through the connecting pipe 303, and the mixed liquid after separation and electrocatalysis falls into the storage box 304 again to achieve recycling and reuse.

[0035] Specifically, a baffle 501 is fixedly installed on the inner wall of the dust reduction chamber 5 , and the electrocatalytic regenerator 306 is located in a cavity formed between the baffle 501 and the dust reduction chamber 5 .

[0036] In this embodiment, the baffle 501 can be used to protect the electrocatalytic regenerator 306 , thereby preventing the copper sulfate solution from contacting the electrocatalytic regenerator 306 and causing damage to the electrocatalytic regenerator 306 .

[0037] When in use, the hydrogen sulfide gas is first introduced into the adsorption chamber 3 through the air inlet pipe 2, and the hydrogen sulfide gas is forced to pass through multiple adsorption nets 302, so that the adsorption nets 302 filter and adsorb impurities in the hydrogen sulfide gas, and then the hydrogen sulfide gas is introduced into the storage box 304 below the liquid level through the connecting pipe 303, and the storage box 304 is injected with an absorption liquid containing sodium hydroxide, sodium chloride and oxygen-rich ion water, which will react with the hydrogen sulfide gas, and then the extraction pump 305 is started, so that the extraction pump 305 draws the mixed liquid formed by the reaction of the absorption liquid and hydrogen sulfide in the storage box 304 into the electrocatalytic regenerator 306, so that the electrocatalytic regenerator 306 performs an electrocatalytic regeneration reaction on the mixed liquid, and promotes the hydrogen sulfide in the mixed liquid to oxidize into sulfate, and then these substances enter the gas-liquid separation layer 7 for gas-liquid separation, and the purified gas will enter the dust reduction chamber 5, and the mixed liquid after separation of electrocatalysis will fall into the storage box 304 again to achieve recycling and reuse;

[0038] Then, the water tank 505 is opened, and the water tank 505 is prompted to inject the copper sulfate solution into the interior of the atomizing nozzle 507 through the shunt pipe 506 through the water pump arranged at the bottom thereof. Then, the atomizing nozzle 507 can spray the copper sulfate solution in the water tank 505 into the dust reduction chamber 5 in the form of mist, so that the copper sulfate solution will form copper sulfide which is insoluble in general strong acid when reacting with the preliminarily purified hydrogen sulfide gas, and finally fall into the waste residue box 504 and wait for the staff to recycle it;

[0039] When the waste box 504 needs to be disassembled, the rotating pin 503 needs to be rotated in advance so that the rotating pin 503 and the waste box 504 are released from the overlapping state, so that the splicing state between the waste box 504 and the installation recess 502 is released. Then the staff can remove the waste box 504 from the opening of the installation recess 502 and recycle the waste inside the waste box 504.

[0040] The gas after the above purification operation is finally discharged from the purification box 1 under the drive of the outlet fan 601.

[0041] In summary, the hydrogen sulfide gas purifier is provided with a storage box 304, an electrocatalytic regenerator 306 and a gas-liquid separation layer 7, and uses the absorption liquid in the storage box 304 to react with the hydrogen sulfide gas, thereby absorbing hydrogen sulfide and stabilizing it into a mixed liquid, and then cooperates with the extraction pump 305 to pump the mixed liquid into the electrocatalytic regenerator 306 for electrocatalytic regeneration reaction, so that the hydrogen sulfide in the mixed liquid is oxidized into sulfate, and finally the gas-liquid separation layer 7 can perform gas-liquid separation on the mixed liquid, so that the separated electrocatalytic mixed liquid falls into the storage box 304 again, thereby Realize recycling and reuse, so that the hydrogen sulfide gas undergoes multi-stage purification; by setting up a waste slag box 504, a water tank 505 and an atomizing nozzle 507, the copper sulfate solution in the water tank 505 can be sprayed in the dust reduction chamber 5 in the form of mist using the atomizing nozzle 507, so that the copper sulfate solution will form copper sulfide that is insoluble in general strong acid when reacting with the hydrogen sulfide gas after preliminary purification, and finally fall into the waste slag box 504 and wait for the staff to recycle it, so that the hydrogen sulfide gas is purified at the second level, thereby further improving the practicality of the purifier.
