Description

Technical Field

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

[0002] Hydrogen sulfide (H2S) is a colorless, highly toxic acidic gas. It is an inorganic compound with no noticeable odor at high concentrations, a strong smell of rotten eggs at low concentrations, and a sulfur smell at very low concentrations. It is a byproduct of many industrial processes, such as natural gas refining, oil refining, wastewater treatment, and papermaking. It is also produced in nature through the decomposition of organic matter and the metabolic activities of certain microorganisms. The density of hydrogen sulfide is slightly greater than that of air, and it can accumulate in low-lying areas, forming potential danger areas. It is toxic to the human body at low concentrations, and inhaling high concentrations of hydrogen sulfide can quickly kill people. It inhibits cellular oxidative phosphorylation, hinders cellular respiration, and causes cell death. Hydrogen sulfide is irritating to the eyes, respiratory system, and nervous system. Exposure to low concentrations may cause eye irritation, headaches, coughing, and difficulty breathing.

[0003] Traditionally, the removal of hydrogen sulfide from gas by spray purification often uses a single nozzle for spraying, which sometimes makes it difficult to purify the gas completely, thus affecting the purification and removal effect of hydrogen sulfide. Therefore, a device for removing hydrogen sulfide from gas is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a device for removing hydrogen sulfide from gas to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for removing hydrogen sulfide from gas, comprising a purification tank, a support frame is fixedly arranged on the surface of the purification tank, a connecting pipe is fixedly arranged inside the upper surface of the purification tank, a connecting pipe is rotatably connected to the bottom end of the connecting pipe, a spray pipe is connected to the bottom end of the connecting pipe, a plurality of liquid spray heads are connected to the lower surface of the spray pipe, a connecting rod is fixedly connected to the lower surface of the spray pipe, a stirring blade is fixedly arranged at the bottom end of the connecting rod, a limiting ring block is fixedly arranged inside the purification tank, and a liquid spray head is connected to the bottom end of the connecting rod. The limiting ring block is divided into a spray chamber and an aeration chamber at the upper and lower parts of the dividing line, the stirring blade is located in the aeration chamber, one side of the purification tank is connected with an air inlet pipe, one end of the air inlet pipe is connected with a jet head, a first gear is fixedly provided on the outside of the connecting pipe, and a second gear is rotatably connected inside the purification tank, the first gear and the second gear are meshed with each other, and a driving motor is provided at the rotating part of the second gear on the upper surface of the purification tank, the top end of the connecting pipe is connected with a circulation pipe, one end of the circulation pipe is connected to the lower surface of the purification tank, and a circulation filter pump is provided on the circulation pipe.

[0006] By setting the above structure, when the gas enters the purification tank from the air inlet pipe, it will first enter the aeration chamber. Since the purification agent is placed in the aeration chamber and the hydrogen sulfide in the gas is easily soluble in water, the gas ejected from the jet head will be aerated and purified to a certain extent in the aeration chamber, and when the gas passes through the limiting ring block and enters the spray chamber, the circulating filter pump can circulate the agent in the aeration chamber to the spray head on the spray pipe and spray the hydrogen sulfide. During this period, the spray pipe and the spray head are driven to rotate through a series of transmissions under the operation of the drive motor, so that the spray pipe and the spray head can increase the fullness of the spray in the spray chamber by rotation, and the spray pipe will drive the stirring blades to synchronously stir and rotate in the aeration chamber through the connecting rod, so that the aerated gas in the aeration chamber can be mixed more fully, which helps to increase the quality of aeration purification, and then the effect of removing hydrogen sulfide from the gas is enhanced through the double purification of hydrogen sulfide up and down, thereby helping to ensure the high-quality gas hydrogen sulfide removal effect.

[0007] As a preferred implementation, the upper and lower surfaces of the limiting ring block are both bucket-shaped.

[0008] As a preferred implementation, the jet head is located in the aeration chamber.

[0009] As a preferred implementation, the drive motor is fixedly mounted on the purification tank.

[0010] As a preferred embodiment, the upper surface of the purification tank is connected to an air outlet pipe.

[0011] As a preferred embodiment, the lower surface of the purification tank is connected to a liquid outlet, and a valve is provided on the liquid outlet.

[0012] By setting the upper and lower surfaces of the limiting ring block to be bucket-shaped, on the one hand, the restriction and guidance of the bucket shape below the limiting ring block can prevent the purification agent from splashing chaotically in the purification tank when the stirring blade is stirring and rotating, thereby ensuring the stability of the machine body operation, and the gas can also enter the spray chamber for spraying through the guidance of the limiting ring block. On the other hand, the setting of the bucket shape above the limiting ring block can facilitate the liquid sprayed from the spray head to flow back into the aeration chamber, thereby contributing to the recycling effect of the purification agent liquid in the aeration chamber.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides an aeration chamber. When gas enters the purification tank from the air inlet pipe, it first enters the aeration chamber. Since purification agents are placed in the aeration chamber and hydrogen sulfide in the gas is easily soluble in water, the gas ejected from the jet head is aerated and purified to a certain extent in the aeration chamber. When the gas enters the spray chamber through the limiting ring block, the agent in the aeration chamber can be circulated and transported to the spray head on the spray pipe under the operation of the circulating filter pump, and the hydrogen sulfide is sprayed. During this period, the spray pipe and the spray head are driven to rotate through a series of transmissions under the operation of the driving motor, so that the spray pipe and the spray head can increase the fullness of the spray in the spray chamber by rotation, and the spray pipe can drive the stirring blades to synchronously stir and rotate in the aeration chamber through the connecting rod, so that the gas aerated in the aeration chamber can be mixed more fully, which is helpful to increase the quality of aeration purification, and then the effect of removing hydrogen sulfide in the gas is enhanced through the double purification of hydrogen sulfide up and down, thereby helping to ensure the high-quality gas hydrogen sulfide removal effect.

[0015] The utility model sets the upper and lower surfaces of the limiting ring block to be bucket-shaped. On the one hand, the limiting and guiding of the bucket shape below the limiting ring block can prevent the purification agent from splashing chaotically in the purification tank when the stirring blade is stirring and rotating, thereby ensuring the stability of the machine body operation, and the gas can also enter the spray chamber for spraying through the guidance of the limiting ring block. On the other hand, the setting of the bucket shape above the limiting ring block can facilitate the liquid sprayed from the liquid spray head to flow back into the aeration chamber, thereby contributing to the recycling effect of the purification agent liquid in the aeration chamber.
